Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an empty area display device for displaying an empty area in a storage section of an on-vehicle electrical load having a storage section for presetting a plurality of operation control data.

One of the devices currently being researched by the inventors of the present application is an electric seat/mirror device.This device can be used to adjust seat positions and side mirrors to suit each driver in advance, such as when multiple drivers take turns driving. The angles of the mirrors (hereinafter simply referred to as mirrors) are preset in separate memory areas, and when changed by the driver,
If the preset data corresponding to the driver is selected by operating a specified switch, the seat and mirrors are automatically set to the memorized setting position, eliminating the need to manually adjust the seat and mirrors. It's convenient.

By the way, in the above device, if the storage area (hereinafter referred to as empty area) in which no data is stored is displayed, those who do not know the stored contents will
When attempting to perform a new preset operation, it is not possible to determine which storage area is an empty area, resulting in inconveniences such as accidentally erasing data in a storage area that has already been preset. It was recognized that it would be convenient if it were possible to erase unnecessary data such as data that is not used often among the preset data.

This invention has been made based on the background described in section 2, and its purpose is to provide an on-vehicle electrical load with a preset memory section, such as the electric seat mirror and device described above, by operating a predetermined switch. The present invention aims to prevent erroneous operations during preset operations and improve operability by making it possible to erase desired preset data and displaying empty areas in the Mf storage section.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

1 to 4 are diagrams showing the structure of an electric mirror of an embodiment of the electric mirror device according to the present invention.

This electric mirror is an outside mirror M, and inside the mirror body 1 of this outside mirror M, a unit case 2 is fixed to the port 1 via 3, and the mirror body 4 is fixed to the top, bottom, left and right. hx so that it can rotate by a predetermined angle in the direction.

A motor 5 is fixed in the unit case 2 as shown in FIGS. 1 and 2, and a magnetic body 7 with N and S poles on one end of the motor shaft 6 of the motor 5 is fixed. is fixed to a rotatable OL integrally with the shaft, and the other end is fixed to an electromagnetic clutch 8 having a speed reduction mechanism such as a planetary gear type reduction gear.

Then, when the electromagnetic clutch 8 is energized, the motor 5
The rotational output of is appropriately decelerated and linked to a pinion gear (for underground movement) 9, and when A is turned, it is linked to a pinion gear (for left and right rotation) 10.

As particularly shown in FIG. 3, the above-mentioned pinion gear 9 meshes with a fan-shaped joint gear 11. One end of this joint gear 11 is connected to a bracket 12 attached to the back surface of the mirror body 4. The mirror 4 is configured to rotate in the vertical direction with the bottle 13 as the center of rotation.

Further, projections 14 are provided at the upper and lower ends of the joint gear 11.
．． The projections 14 and 15 act to press and turn on the limit switch 16 provided on the unit case 2 when the join 1 to the gear 11 are rotated to their upper and lower end positions.

Historically, there is some elastic meshing play between gears 9 and 11, so if you try to forcefully rotate the mirror body up and down while the motor is fixed, both gears 9 and 11 will
, 11 become disengaged, causing idle rotation.

In addition, as shown in FIG. 4, the pinion gear 10 has a
)ff is meshed with a slide gear 18 that is movable in the rear direction, and one end of this slide gear 18 is connected to the bracket 12 of the mirror main body 4 via a ball joint 19.

The rotation of the seat S is transmitted by a planetary gear reducer to a rack attached to the lower surface of the seat S, and the seat S is moved back and forth and moved up and down.

In addition, in order to detect the moving position of the seat S, similarly to the electric mirror, a magnetic body is attached to the rotating shaft of each motor 62, 63, and a pulse signal is generated by turning on and off by the magnetic force of this magnetic body. Reed switches 64 and 65 are provided for input to the microcomputer 36.

Furthermore, at the end of the movement of the seat S back and forth and up and down, the limit switches 66, 67, 68, and 69 provided in the respective movement directions are turned off, and these limit switches 66.67.68.

Next, FIG. 8 to FIG. 10(B) are flowcharts schematically showing the structure of the system program executed in the micro combi coater 36, and the operation of this embodiment apparatus will be systematically explained in accordance with this flowchart. explain.

The electric seat/mirror device according to this embodiment has a manual mode in which the mirror and seat are set at desired positions by operating a manual switch from the driver's seat, and a manual mode in which the mirror and seat are set to desired positions by operating a manual switch from the driver's seat. Two operation modes can be selectively used, including a preset return mode in which the seat and mirror positions are set to desired positions by one-touch operation of the channel switches 53 to 56 based on the individual data.

Therefore, the operation in manual mode will be explained in detail.

In the following explanation of the operation, for convenience of explanation, the operation of the mirror will be representatively explained for only the right mirror, but it goes without saying that the same explanation can be given for the left mirror as well.

In manual mode operation, although not particularly shown in the flowchart, the microcomputer 36 always outputs the pulse train output from the reed switch 24R via the boat P3, the pulse train output from the reed switch 64 via the boat P31, and the boat P34. The pulse train output from the reed switch 65 is counted, and it is detected whether the motor 5R is rotating in the normal direction or in the reverse direction, depending on the logic state of the boats P5 and P6.

Then, the manual switch 51 is connected via the boat PI7.
The state of the output S1 is taken in, and based on this, it is detected whether the mirror main body 4 is rotating in the vertical direction or the horizontal direction.

Also, depending on the state of boat P17, it is determined that the mirror is rotating in the left and right direction, and boat P5. If the direction of rotation is determined to be rightward or leftward according to the state of P6, the contents of counter As a result, the contents of the counter X always correspond to the current position of the mirror in the left-right direction.

On the other hand, if it is determined that the mirror is rotating in the vertical direction based on the contents of boat PI7, similarly, boat P5. Depending on the contents of P6, the contents of the counter Y indicating the current vertical position of the mirror are incremented by +1 or -1, so that the contents of the vertical counter Y always correspond to the current vertical position of the mirror. Become.

Furthermore, the normal rotation and reverse rotation states of the motors 62 and 63 are detected depending on the logic states of the boats P3F and P40.

And boat p37. P: When it is determined that the seat is raised or lowered based on the logic state of +e, the contents of the counter N indicating the current vertical position of the seat 1- are set to +1 or -.
1, so that the contents of the counter N always correspond to the current position of the sheet in the vertical direction.

Similarly, boat P39. Based on the logic state of P40, the current position of the seat in the front-rear direction is incremented by 1-counter M by +1 or -1, so that the contents of counter M always correspond to the current position of the seat in the front-rear direction. becomes.

Since the microcomputer 36 performs the above operations, in this state, if you operate the manual switch appropriately and rotate the mirror body vertically or horizontally to position it at the desired angle, the counter The contents of counter M and counter Y will correspond to the current position of the mirror at that time, and if the seat is set to the desired position and height, the contents of counter M and counter N will be as follows.
This corresponds to the current position of the sheet at that time.

Next, the mirror coordinate data formed on the X and Y counters and the sheet coordinate data formed on the M and N counters by the above operations are stored in the memory of the designated channel in the microcomputer 36. Steps 1 to 1 will be performed.

However, when presetting the seat and mirror setting positions to this memory, the four chilennels 53 mentioned above have already been set.
~56, and if you try to preset new setting data, there is a risk of accidentally erasing necessary data from the already preset data. In particular, when the driver changes or the preset contents are forgotten, the above-mentioned erroneous operation is likely to occur.

Therefore, in this electric seat mirror device, the preset data in the specified channel can be erased, and the storage area of the erased channel is displayed as an empty area. A device that deletes unnecessary preset data such as data that is not used much among the preset data and displays it to prevent the occurrence of the above-mentioned erroneous operations when an unknown person performs a new preset operation. It is.

Hereinafter, the preset data erasing operation for the designated channel will be explained in accordance with the flowchart of FIG. 8.

First, as shown in FIG. 6, four channel switches 53 to 56, a memory switch 57, an erase switch 83, and the above-mentioned stop switch 44 are arranged at appropriate locations near the driver's seat of the vehicle. Erase switch 83
When is pressed, the execution result of step (1) becomes YES in the flowchart of FIG. After being operated, the ON operation of the channel switches 53 to 56 can be detected only for a certain period of time.

In this state, when any of the channel switches 53 to 56 is turned on, the execution result of step (4) is Y.
ES, and the contents of the channel switch are A~
Step (6) depending on which D channel it is.
→ (9) → (10) → (11) → (12) or step (6) → (7) → (13) → (14) → (15) →
(16) Or step (6) → (7) → (8) → (
126-7) → <18) → (19) → (20) or step (6) → (7) → (8) → (21) → (22) -> (2
3)→(24) is alternatively executed.

As a result, for example, if the operated channel switch is the A channel, the A channel's mirror left and right position register Ax, mirror up and down position register △y, seat front and rear position register Am, sea 1 to upper and lower times register Art
In each case, a zero code (one of the count values of counters X, Y and counters M, N, which cannot be taken within the movement range of the mirror and sheet, is used as the zero code instead of the previously stored preset data). ) will be stored and the preset data will be deleted.

Similarly, when other channel switches are pressed, a zero code is stored in each register corresponding to each channel.

Next, after the positions of the seat and mirrors have been set to positions suitable for the driver by the manual operation, the operation and process of presetting the current positions of the seats and mirrors in the memory of a predetermined channel are shown in FIG. The explanation will be given according to the flowchart.

First, when the memory switch 57 is pressed, the execution result of step (31) becomes YES in the flowchart of FIG.
The contents of × are transferred and stored in the code determination register K.

Next, the process proceeds to step (33), where it is determined whether the data transferred to the code determination register K is zero]-code, and if the result is YES, the memory contents of this A channel are erased. If it is determined that the area is empty, the process proceeds to step (34), where the LED 40 provided above the A channel switch 53 is turned off to indicate that the A channel is a vacant area.

Further, if the above judgment result is No, it is judged that preset data is stored in this A channel, and the above LED 4Q is lit to display that this A channel has been preset.

Following steps (36) → (33) → (34) or (3)
5)→(36)→(37) are executed to determine whether or not the three channels in the square are empty areas, and the LEDs 41, 42 and 43 are turned on and off based on the determination result.

As a result, the LED of the channel that is an empty area among the four channels is turned off, and it can be determined by looking at which channel new data can be preset.

Therefore, next steps (38) → (39) → (40)
→If you turn on the channel switch of the channel on which the empty area is displayed during the waiting time of channel switch operation by processing (38), the current position of the seat and mirror set by the above manual operation will be applied to this channel. will be preset.

That is, when any of the channel switches 53 to 56 is turned on, the execution result of step (38) becomes YES, and the content of the channel switch is changed depending on which channel A to D is selected. Steps (41) → (44) → (45) → (46) → (47) →
(48) Or step (41) → (42) → (49
)→(50)→(51)→(52)→(53) or
Steps (41) → (42) → (43) → (54) → (
55) → (56) → (57) → (58) or step (41) → (42) → (43) → (59) → (60)
→(61)→(62)→(63) are alternatively executed.

As a result, for example, if the operated channel switch is the Δ channel switch 53, the A channel's mirror left/right position register Ax and mirror up/down position register AM
The mirror current position data in the counter
The current position data is transferred and stored in the lower position register An of the sheet and the sheet 30--1 in the counter M and counter N formed by the manual operation, respectively.

Similarly, when other channel switches are pressed, the current position data is transferred and stored in each register corresponding to each channel.

Next, the operations from brisset I to return mode will be explained. Assume now that the A, B, C, and D channels have already stored seat position data and mirror position data unique to each driver. The contents of the mirror position data above are based on the case where the origin (0, O) is the intersection of the end of rightward rotation and the end of downward rotation when the mirror rotates in the left and right direction and in the up and down direction. , is stored as the amount of relative displacement from this origin.

In this state, when the ignition switch 33 is turned on, the flowchart shown in FIGS. 10(A> and 10B) starts.

When a program starts, first step (71)
is executed, it is determined whether the memory state has been properly updated, and step (72) is selectively executed according to the result of the determination, and finally the information in the working area is Each register, memory, etc. is set to a predetermined initial state.

Next, when step (73) is executed, it is determined whether or not a channel switch has been operated, and if any of the channel switches 53 to 56 has been suppressed, step (73) is executed. The result is YES,
Subsequently, origin return processing is performed.

Here, the origin 1u return process is a process of making the contents of the counter X representing the current position of the mirror in the horizontal direction and the counter Y representing the current position of the mirror in the vertical direction coincide with the actual current position of the mirror. This origin return processing is performed for the following purposes.

That is, as mentioned above, in the middle of the rotation transmission system from the motor 5 to the mirror body 4, an idle mechanism consisting of a pinion gear 1o and a slide gear 18 is provided for rotation in the left and right direction, and an idle mechanism for rotation in the vertical direction. Regarding the rotation, an idle mechanism consisting of a pinion gear 9, a joint gear 11, etc. is similarly provided.

The original purpose of these idling mechanisms is different from the original purpose when the motor 5 breaks down and the motor shaft is locked, which causes the mirror body 4 to be fixed at an angle inappropriate for the driver. Even if the motor shaft is fixed, the mirror main body 4 can be manually rotated by an external force using these free rotation mechanisms to set it at the optimum angle.

Therefore, even if the electric mirror device malfunctions, the dangerous situation where the mirror body 4 is fixed at an inappropriate angle and you are forced to continue driving without being able to fully see what is behind you can be prevented. It's about doing.

However, if only the mirror main body 4 is configured to be rotatable by external force regardless of the rotation of the motor shaft, the mirror main body 4 may accidentally come into contact with some object while the vehicle is parked and rotate. Or a child may play a trick and Mira's body 4
In such a case, the current position data stored in the counters X and Y described above will no longer match the actual position of the mirror, and each channel A described above.

It becomes impossible to restore the mirror to the desired angle using the stored data B, C, and D.

Therefore, the function of the return-to-origin process is to match the contents of the counters X and Y with the current position of the mirror body so that the mirror body can be set at a desired angle using the data of each channel.

The actual processing involves detecting the on/off states of limit switches 16R and 23R, which detect the end of the mirror's movement, and moving the mirror angle to a predetermined origin. When the mirror angle reaches the origin position, the contents of the counters X and Y are set to O.
A reset process is performed.

Next, when the above-described return to origin process in the left-right direction and downward direction is completed, the return process to Priscella 1 is subsequently started.

When the preset restoration process is started, in the flowchart of FIG. 10 34-(△), step (75)→( 78) → (7) → (80)
→ (81) → (82) → (83) or step (7
5) → (76) → (84) → (85) → (86) → (8
7) → (88) → (89) or step (75) →
(76) → (77) → (90) → (91) → (92) →
(93) → (94) → (95) or step (75
)→(76)→(77)→(96)→(97)→(98
)→(99)→(100)→(101) is alternatively executed.

Then, the preset data stored in the X register and Y register of the corresponding channel is transferred to the preset register 7x in the horizontal direction and the preset register Zy in the vertical direction of the mirror, and then the preset data stored in the The preset data stored in the M register and N register of the corresponding channel is transferred to the preset register wm and the vertical preset register Wn, respectively.

At this time, by lighting only the LED of the designated channel, it is displayed on which channel the preset operation is currently being performed.

Next, when step (102) is executed, the calculation ZX-X is performed between the mirror left-right preset register ZX and the mirror left-right current position register X, and the calculation result is It is stored in the left-right direction deviation register εX.

Next, when step (103) is executed, it is determined whether the contents of the deviation register ε× are positive or not.

Here, the fact that the value of the deviation register ε× is positive means that the horizontal rotation position indicated by the preset data is
This means that it is on the left side of the rotational position of the mirror main body 4 at the present time. Therefore, the contents of the deviation register εx immediately after the start of the preset return process become positive, and step (104) is subsequently executed, and the mirror main body 4 begins to rotate to the left.

Next, when the counter increment process consisting of steps (105) to (107) is performed, the contents of the current position register X in the left and right direction are incremented in response to the pulse train output from the reed switch 24R. Thereafter, until the contents of the preset register Zx and the contents of the current position register X match, steps (102) → (103) → (10
4) → (105) → (106) → (107) → (102
) is executed repeatedly.

Next, when the horizontal rotation position specified by the preset data matches the current rotation position, step (10
The execution result of step 3) is No, and then step (108
) is executed, the mirror rotation operation in the left-right direction is stopped, and the left-right direction preset return process is thereby completed, and then the vertical direction preset process is started.

When the vertical preset process starts, step (
109) is executed, and the vertical briset of the mirror]-
The calculation Zy-Y is performed between the register Zy and the mirror vertical direction = 37- current position register Y, and the calculation result is stored in the mirror vertical deviation register εy.
stored in

Next, when step (110) is executed, it is determined whether the contents of the vertical deviation register εy are positive.

Here, the fact that the content of the vertical deviation register εy is positive means that the mirror rotational position in the vertical direction indicated by the vertical preceramic data is equal to the actual rotational position dJ of the mirror at that time. It means to be located above. Therefore, immediately after starting the preset return process in the vertical direction, the execution result of step (110) becomes YES, and then step (111) is executed, and the mirror main body 4 starts rotating upward.

Next, when the counter increment process consisting of steps (112) to (114>) is executed, the value of the vertical current position register Y is counted up in response to the pulse train output from the reed switch 24R.

38- After 1 step, steps (109) → (110) → (111) are performed until the vertical rotation position indicated by the preset data and the actual rotation position of the mirror body are equal to each other. )
→(112)→(113)→(114)→(109) are repeatedly executed.

Next, when the vertical rotation position indicated by the preset data matches the current rotation position of the mirror, the execution result of step (110) becomes NO, and step (115) is subsequently executed. , the rotation of the mirror main body in the vertical direction is stopped, thereby completely completing the preset return process in the horizontal and vertical directions of the mirror.

After the mirror preset return process is completed, the seat preset return process is carried out in the same manner, and this process will be described with reference to the flowchart of FIG. 1(B).

When the process of the final step (115) in FIG. A calculation Wllll-M is performed, and the result of the calculation is stored in the sheet longitudinal direction deviation register εm.

Next, when step (117) is executed, it is determined whether the contents of the longitudinal deviation register εm are positive or not.

Here, the fact that the content of the longitudinal direction deviation register εm is positive means that the position of the seat in the longitudinal direction indicated by the preset data in the longitudinal direction of the seat is located in front of the current position.

Therefore, if the content of the deviation register εm is positive, step (119) is executed and the sheet starts moving forward.

Next, the counter increment process consisting of steps (120) to (122) is executed, and the current position register M in the longitudinal direction is
The value of is counted up in response to the pulse train output from the reed switch 65, and thereafter the sheet moves forward, step by step (
116) → (117) → (119) → (120) → (1
21)→(122)→(116) are repeated.

Further, if the content of the longitudinal direction deviation register εm is negative, the seat position indicated by the longitudinal direction preset data is behind the current position, and steps (116)→(117)→ (118) → (123
) is executed, the backward movement of the seat 1- is started, the following steps (125) → (126) → (127) are executed, the countdown process of the current position register M in the front and rear direction is performed, and the seat moves backwards and this process is repeated until the preset position is reached.

If the contents of the front-back deviation register εm become O, it is determined that the sheet coincides with the preset position in the front-back direction, and the process of step (128) is executed to perform the front-back movement. energization of the motor 63 is stopped,
The preset restoration process in the front and back direction of the seat is completed.

Thereafter, similar processing is performed to position the sheet up and down to preset positions 41-.

That is, in step (129>), the calculation Wn -N is performed between the sheet vertical preset register wn and the sheet vertical current position register N, and the calculation result is stored in the sheet vertical deviation register εn. be done.

Then, in step (130) or (131), whether the vertical deviation register εn is positive, square, or O
Steps (130) → (132) → (depending on whether
133) → (134) → (135) or step (
130) → (131) → (136) → (137) → (1
3B)→(139) is executed to move the seat upward and count up the current position register N in the vertical direction, or move the seat downward and count down the current position register N in the vertical direction.

When the value of the vertical deviation register εn becomes O and it is determined that the sheet matches the preset position in the vertical direction, the process of step (140) is executed and the motor 42-62 for vertical movement is executed. energization is stopped, and the pre-seller 1- in the vertical direction of the sheet
The return process ends.

In addition, in the above embodiment, the electric seat 1 to mirror device for a vehicle is shown to be capable of erasing preset data, but the present invention is not limited to this, and can be applied to other vehicle electrical loads, e.g. It is clear that similar effects can be obtained when applied to a presettable near conditioner or a presettable radio or audio tuner.

Further, in the above embodiment, the preset data erasing operation is performed by ONIM operation using a separately provided erasing switch. If two switches for other processing are used as key switches, and the above erase process is performed by turning on these two key switches in sequence, it is possible for a child to accidentally press the erase switch as a mischievous child. It is possible to prevent necessary preset data from being deleted.

Furthermore, in the above embodiment, a reed switch is used as a small rotation detector, but in addition to this, a Hall element or the like that detects the magnetic flux of the magnetic body 7 may be used for detection.
Of course, the present invention is not limited to the reed switch.

As described in detail above, in the vacant area display device of the present invention, desired preset data can be erased by operating a predetermined switch in an on-vehicle electrical load having a preset storage section, and the By configuring the display to display the empty area within the section, it is possible to prevent erroneous operations during preset operations and improve operability.
