Description

[Detailed explanation of the idea] [Purpose of invention]

(Field of Industrial Application) This invention relates to an electric load control device suitable for driving a driven object, such as an electric seat device or an electric mirror device, to a pre-stored position using an electric load. (Prior Art) Various types of electric load control devices as described above have been proposed in the past, but here,
This will be explained using an electric seat device as an example. In other words, the preset storage means stores the operation data of each part of the seat (for example, reclining, slide, lifter) adjusted by manual operation for each driver from the output of the position detection means in response to the preset storage operation, and There is a configuration in which the operating data stored in the preset storage means is output by a switch operation, and each part of the seat is adjusted for each driver. When you press the button, the buzzer will sound and all the visual indicators corresponding to the addresses of the preset storage means that store the operation data will light up during the storage standby time, and the address switch corresponding to the address you want to store will be turned on. When pressed, a buzzer sounds and the corresponding visual indicator lights up even after the storage standby time has elapsed, informing the driver that the operation data has been stored to the corresponding address.

is stored, the LED corresponding to the corresponding address is stored for a storage standby time (first time: approx.
When the address switch corresponding to the address where the operation data is stored is operated during the storage standby time, the LED corresponding to the address is turned off for a predetermined time (second time).
After being turned off for about 0.5 seconds, the light is turned on continuously to notify the completion of storing new operation data.If no operation data is stored in either or both addresses A and B in the storage standby state, ,
When the LED corresponding to the corresponding address is turned on for a predetermined time (third time: about 0.5 seconds) and the address switch corresponding to the address where no operation data is stored within the storage standby time is operated, It is configured to continuously light the LED corresponding to the corresponding address to notify the storage completion state that storage has been completed.

Note that the power supply circuit 65 is constantly supplied with power from the battery 70 and holds a program built in the microcomputer 61. Next, the function realizing means built into the above-mentioned microcomputer 61 will be specifically explained using the flowchart shown in FIG. In step 101, it is determined whether or not the set switch 53 has been turned on. If it is determined that the set switch 53 has not been turned on (NO), the process moves to step 200, and the seat device 20 is turned on manually or automatically. It becomes possible to adjust each part of the If it is determined in step 101 that the set switch 53 has been turned on (YES), the process proceeds to step 102. Then, in step 102, it is determined whether or not there is an address in the memorized state, and if it is determined that there is an address in the memorized state (YES),
In step 103, an instruction is given to turn on the LED corresponding to the address in the storage state, and an instruction is given to turn on the LED corresponding to the address not in the storage state for 0.5 seconds. Then, in the next step 105, it is determined whether or not the set switch 53 has been turned off. If it is determined that the set switch 53 has not been turned off (NO), the process returns to step 102 and it is determined that the set switch 53 has been turned off. The above state will continue until a decision is made. Furthermore, if it is determined in step 105 that the set switch 53 has been turned off (YES), in the next step 106 a 5-second timer starts counting, and the process moves to the next step 107. Then, in step 107, it is determined whether the 5-second timer has finished counting, and if it is determined that the 5-second timer has finished counting (YES).
In step 108, the light is on.
Instructs to turn off the LED and moves to step 200. If it is determined in step 107 that the count of the 5-second timer has not finished (NO), then in the next step 109 it is determined whether either of the address switches 51, 52 has been turned on or not. If it is determined that neither address switch 51 or 52 is turned on (NO), step 200 is performed.
to move to. If it is determined in step 109 that one of the address switches 51 and 52 has been turned on (YES), then in the next step 110, the address switch determined to have been turned on in step 109 is turned on. It is determined whether or not the corresponding address is in the memorized state, and if it is determined that the corresponding address is in the memorized state (YES), in step 111, the LED corresponding to the address is turned off for 0.5 seconds. Instruct the machine to proceed to step 200. Also, if it is determined in step 110 that the corresponding address is not stored (NO)
In step 112, the LED corresponding to the address is turned on, and the process proceeds to step 200. Next, the operation of the electric seat device having the above configuration will be explained with reference to FIGS. 6 and 7. First, when the ignition switch 71 is turned on, a program built in the microcomputer 61 starts operating. Next, when the set switch 53 is turned on, step 101 shown in FIG. 4 makes a determination of "YES", and the preset storage means in the microcomputer 61 shown in FIG. 3 enters a storage standby state. At this time, address A of the preset storage means,
If no operation data is stored in any of B, step 102 determines "NO" and all
Step 104 turns on LEDs a and b for 0.5 seconds as shown in FIG. 7a. In addition, the addresses A and B of the preset storage means are
If the operational data is stored in any of the addresses, step 102 determines "YES", and at this time, for example, assuming that the operational data is stored in address A and that no operational data is stored in address B. To explain, step 103 turns on LEDa as shown in FIG. 6a, and turns on LEDb for about 0.5 seconds as shown in FIG. 7a. Therefore, by turning on the set switch 53, it is possible to display addresses in which operational data is stored and addresses in which no operation data is stored, and to inform the driver of vacant addresses. Then, when the set switch 53 that was turned on is turned off, step 105 determines "YES", and step 106 activates a 5 second timer to continue the storage standby state for 5 seconds (memory standby state). If either address switch 51 or 52 is turned on while this 5-second timer is operating, step 109 will determine "YES" and at this time, for example, operation data (number of pulse signals) will be stored at address A. Assuming that the address has been stored, when the address switch 51 corresponding to address A is turned on, the operation data of each part of the seat device 20 shown in FIG. 2 is transferred to the position detector 12 shown in FIG. 3.
. . . 15 to address A, and step 111 reads LEDa as shown in FIG. 6b.
turns off for 0.5 seconds and then turns on continuously. Therefore, it becomes possible for the driver to recognize the storage completion state in which re-storing to address A has been completed. In addition, address B that does not store operation data
In this case, when the corresponding address switch 52 is operated, the operation data of each part of the sheet device 20 shown in FIG. 2 is transmitted to the position detectors 12 to 1 shown in FIG.
The output of step 5 is stored at address B, and the step
112 lights up the corresponding LEDb continuously as shown in FIG. 7b. Therefore, it becomes possible for the driver to recognize the storage completion state in which storage to address B has been completed. When the storage of the operation data at the address of the preset storage means is completed, the corresponding LED continues to be lit even after the storage standby time has expired. In addition, in the above embodiment, the case where LEDs a and b are used to display the memory status is explained, but a visual indicator such as a lamp that can be turned on and off may also be used, and is not limited to LEDs. do not have.
