4 is a switch that is turned on when the door is unlocked.

The switch 15 is a switch that is linked to the on/off operation of the ignition switch, and when the ignition switch is turned off when the engine is stopped, the switch 15 also changes from the on state to the off state.

A push-button type activation switch 17 is provided near the door handle on the driver's seat side, and when the activation switch 17 is pressed, a transmission request signal is wirelessly transmitted from the on-vehicle device 1 as described later.

In the device of this embodiment, two types of encoded transmission request signals, A and B, are set as the transmission request signal.

Then, as will be described later, a position code A or B transmitted from the portable device in response to each request signal A or B is received by the transmitter/receiver 110, and a position select signal corresponding to this position code A or B is received. A or B is output from the transmission control section 9 to the controller 2 side.

On the other hand, the controller 2 is for adjusting and controlling the positions of electric equipment such as seats and mirrors, and includes a microprocessor (MPLI) 20. ROM21 and RAM22

When the vehicle user turns on the starting switch 17 to get into the vehicle, the output of the starting switch 17 is supplied to the interrupt input of the MPU 4 via the input interrupt circuit 18, thereby causing the third
The flowchart shown begins.

In steps (400) to (416) in FIG. 3, the driver's seat side door is locked and unlocked.

First, by turning on the start switch 17, the request signal A is outputted in step (400).

This is the transmitter/receiver 10. This is a process of transmitting the request signal A via the loop antennas 11 and 12.

On the other hand, the portable device 3 side is always in a reception standby state, and in the first step (500) in FIG. 4, it is determined whether or not the request signal A has been received.

Here, if the portable device 3 of this embodiment corresponds to the request signal A, the request signal △
is transmitted, an affirmative determination is made in step (500) and the process proceeds to the next step (502).

In step (502), unique code data registered in advance in the ROM3B is read out, and the next step (502) is read out.
04), this unique code data is sent to the transceiver 36. It is transmitted via the loop antenna 37.

The ms*m1 side waits to receive data from the portable device 3 side, and if it is determined in step (402) that data has been received, the process advances to step (408).

If it is determined in step (402) that no data has been received, the process advances to step (404) and request signal B output processing is performed.

In the next step (406), it is determined whether or not data is being received on the portable device 3 side, similarly to the step (402). If it is determined in this step (406) that there is reception, the process also proceeds to step (408).

In step (408), the vehicle body-specific code registered in advance in the ROM 5 is read into the MPU 4, and then in step (410) it is determined whether the received portable device-specific code and the vehicle body-specific code match. , if both codes match, the process advances to step (412).

If it is determined in this step (412) that the driver's side door is locked, the process advances to step (416) and 3. The door lock will be unlocked. If the door is unlocked, the process proceeds to step (414) and is locked.

When the door lock is unlocked as described above, the limit switch 14 is turned on. This is how the driver's riding is detected.

Steps <418) to (428) show the processing from detecting riding to outputting the position select signal.

In step (418), it is determined whether the ignition switch is turned on, that is, whether the switch 15 is turned on or not. If an affirmative determination is made, the process proceeds to step (420).

In step (420), movement alarm sound output processing is performed. This is to notify the seated driver of the start of seat operation by emitting a warning sound such as a buzzer or an alarm.

In the next step (422), it is determined whether the position code is A or not. If the determination is affirmative, the process proceeds to step (424), where the transmission control unit 9 transfers the data to the controller side transmission control unit 26. Position select signal A is output.

Further, if a negative determination is made in the step (422), the process proceeds to step (426), and if it is determined here that the position code is B, the process proceeds to step (428), and from the transmission 1i1JI11 section 9 to the hunt roller The side transmission control unit 26 outputs a hebodisimin select signal B.

In this way, when the position select signal A or B is sent from the transmission control section 9'' of the on-vehicle device 1 to the transmission control section 26 of the controller 2, step (60) of FIG.
0), position select data A or B is MPU2
0 and then step (600)
The reception flag F is set at .

When the reception flag F is set in step (600), the seat and mirror adjustment process shown in FIG. 5(B) is started.
A portrait judgment is made in the first step (604), and the process proceeds to step (606).

In step (606), a personal area is designated by the position selection data A or B stored in step (600) (see FIG. 6), and then in step (60
In step 8), the data of the designated personal area is set in each setting register.

Then, in the next step (610), seat and mirror positioning servo processing is performed based on the data of the designated personal area.

That is, the position data of the individual specified from the MPU 20 via the output interface 23 is transmitted to the seat driver 24. The signal is output to the mirror driver 25, and the seat actuator and mirror actuator are driven by these drivers 24 and 25, so that the seat and mirror are automatically adjusted to the position desired by the driver.

In this way, in this embodiment, when the driver turns on the start switch 17 when getting into the car, the door lock is unlocked wirelessly, and the driver's door lock is unlocked wirelessly depending on whether the ignition switch is turned on or not. Detects riding, mobile II
The seat and mirror positions are automatically adjusted based on the driver's unique position code sent from the third side.

Therefore, unlike the conventional example, there is no need to operate a switch for position adjustment every time you get on the vehicle, which is extremely convenient.

Furthermore, an alarm is emitted before the seat is moved, so that the driver can be informed of the seat movement in advance.

Next, a second embodiment of the present invention will be described using FIGS. 7 and 8. .

In this embodiment, a seat switch 45 is provided in the driver's seat, and the switching signal of this seat switch 45 is transmitted to the input interface 1 as shown in FIG.
The switching signal is supplied to the MPU 4 via the switching signal 6, and the MPU 4 detects that the driver is seated, that is, riding the vehicle. Other components are the same as those shown in FIG. 2. Also, as shown in the flowchart of FIG. 8, when the driver sits on the driver's seat, the seat switch 45 is turned on (step 800); As in the first embodiment, a request signal △ or a request signal B is output as a result of the operation, and the mobile side code and the vehicle body side code sent in response to these are compared (steps 802 to 812), and both codes are verified. If they match, a seat movement alarm sound is generated after the ignition switch is turned on (steps 814 and 816), and then a position select signal A or B is output (steps 818 to 816).
824).

Even with such a configuration, effects similar to those of the first embodiment can be obtained.

In the first embodiment, it is determined that the driver is in the vehicle when the unlocked door is detected, and in the second embodiment, the driver is determined to be in the vehicle when the driver is seated and the seat switch 45 is turned on. Although the configuration is such that it is determined that the driver is in the vehicle, the present invention is not limited to this, and for example, it may be determined that the driver is in the vehicle at the time the ignition switch is turned on.

Next, a third embodiment of the present invention will be described.

In this embodiment, current position data (preset information) of seats, mirrors, etc. is wirelessly transmitted from the in-vehicle device 1 to the portable device 3 side in response to the timing when the driver gets out of the vehicle.
On the side, the received preset information is stored, and when riding the vehicle, automatic position adjustment of the seat, mirrors, etc. is performed based on the stored preset information.

Therefore, in this embodiment, as shown in FIG.
A registration RAM 40 for storing the preset information is provided. Note that the hardware configuration of this embodiment is the first one.
2 used in the embodiment except for the registration RAM 40, the explanation thereof will be omitted.

FIG. 9 is a flowchart showing manual position adjustment of the driver's seat processed within the controller 2 of this embodiment.

The process in the figure starts when any of the manual switches 27 for the seat is operated, and first, if the forward switch 27'a is turned on, step (1000) is executed.
The process then proceeds to step (1002), where a set value P1 of a pulse counter that is built into the MPU 20 and counts the number of output pulses from the pulse generator 32 is incremented, and in the next step (1004), the motor for forward and backward movement is driven. to move the seat forward.

Further, if the reverse switch 27b is turned on, steps (1000) → (1006) → (1008) → (1
010), and after the set value P2 is advanced, the seat is moved backward.

Furthermore, if the lift switch 27C is turned on, the seat is raised after the set value P3 has been increased (steps 1014 and 1016).

If the lowering switch 27d is turned on, the seat is lowered after being advanced by the set value P4 (steps 1020 and 1022>).

When seat control is performed in this way, the set value PI-'
-P'4 is stored as preset data in each of the information areas Δ1 to A4 in the RAM 22 as shown in FIG. 12 (step 1100 in FIG. 10).

Next, the process of reading out the preset setting values P1 to P will be explained. When the individual successive switch 30 shown in FIG. 2 is turned on, a process not shown in FIG. Setting values P1 to P4 are read out, and sheet control is performed by servo processing according to the contents of P1 to P4 (steps 1200 to 1216).

Next, the storage process of preset information on the portable device 1 side at the time of getting off the vehicle, which is a feature of this embodiment, will be explained.

When the driver turns off the ignition switch, the 13th
The processes shown in FIGS. 1 and 14 are started, and first, in step (1500) of FIG. 14, a transfer request signal is outputted from the on-vehicle device 1 to the controller 2 to prompt the transfer of the preset information.

When the transfer request signal is received on the controller 2 side, an affirmative determination is made in step (1400) in FIG. 13, and the process proceeds to step (1402).

In step (1402), the preset data P1 to
P, is transferred to the in-vehicle 1ull side.

Then, when the preset data P1 to P4 are received on the in-vehicle device 1 side, steps (1502) to (1502) are received.
04), and the preset data P1 to P4 are wirelessly transmitted as position codes on a predetermined carrier wave.

On the other hand, FIG. 15 shows the processing on the portable device 3 side,
This portable device 3 is always in a reception standby state, and when a signal from the vehicle-mounted device 1 is received, the process proceeds from step (1602) to step (1604).

In step (1604), whether the received content is a transmission request signal or a position code (the preset data P
1 to P4).

If it is determined in step (1604) that the received content is a position code, the process advances to step (1612), and the received position code is stored in the registration RAM 40.
is memorized.

As described above, when the position code at the time of getting off the vehicle is stored in the portable device 3, the seat and mirror positions are automatically adjusted the next time the vehicle gets on the vehicle based on the stored position data.

That is, as explained in the first embodiment, when the start switch 17 is turned on, a transmission request signal is transmitted from the vehicle 811, and this transmission request signal is sent to the portable device 3.
If received, the process proceeds from step (1604) to step (1606) in FIG.

In this step (1606), the unique code for personal identification stored in the ROM 38 is read into the MPU 35 and transmitted as a unique code signal.

Then, in step (1608), the step (1612
), the position data stored in the registration RAM 40 is transmitted to the on-vehicle device 1.

The vehicle-mounted device 1 identifies the individual based on the received unique code, and automatically adjusts the seat and mirrors to the optimum position for the driver based on the received position code.

Since the position code stored in the portable device 3 is rewritten each time the driver gets off the vehicle, the next time the driver gets on the vehicle, the position is automatically adjusted to the position at the time of the previous alighting.

(Effects of the Invention) As explained above, in the position adjustment device for in-vehicle electric equipment according to the present invention, the positions of the seat, mirrors, etc. specific to the driver are automatically set when the driver is detected to be in the vehicle. Therefore, no special switch operation is required,
This makes it possible to provide an extremely convenient device.
