In the device shown in FIG. 1, the controller 4 is supplied with a power source B (DIR) directly from the on-vehicle battery and a power source B (IGS) after the ignition switch 22.

The key is used as a means for identifying the occupant from the viewpoint of storing the seat slide position and other positions for each occupant and automatically moving the seat when riding the vehicle. 31.32. ．． 33 is a key with a hole in it,
The position and number of holes are changed.

A hole is also made in the key cylinder so that when the key is inserted into the key cylinder 25 of the driver's seat side door and the key is turned in the unlocking direction, the axes coincide with each other. The key sensor 24 is 2
A pair of light emitting diodes and phototransistors are arranged on the round axis between the key hole and the key cylinder hole.

In each of the ender mirrors 63, the mirror surface is operated in two modes (indicated by arrows in FIG. 2): horizontal movement and vertical movement, by motors in detection drive units 611, 621, and 631, respectively.

In the device shown in FIG. 3, the calculation circuit 41 has a read-only memory I
JK Operates according to stored programs. The relay control unit 43 includes the door switch 26, key sensor 24, and B(
IGS) The power relay 42 is controlled by each signal of the power supply. Relay control during riding will be explained with reference to the time chart of FIG. 4. When the key is inserted into the door key cylinder and turned to the unlock side to enter the vehicle, the key cinder 24 detects the key hole and generates a signal. At the rising edge of this key sensor signal, a boarding flag in the relay control section 43 is set. Next, when you open the door, the door switch 26
is turned on, and the drive signal of the transistor 48 is set by the rising edge of the door switch signal and the AND of the boarding flag. Transistor 48 is turned on, relay 42 is turned on, and switching contact 42c is connected to terminal 42b. Power is supplied to the calculation circuit 41, and the calculation circuit 41 operates according to the flowchart shown in FIG.

In step 5102, the flag in the relay control unit 43 is read, and in step 5103, boarding is determined, and in step 8104
The calculation circuit 41 controls the following operations during riding. After automatic movement to the storage position, which will be described later, in step 5113, the boarding flag in the relay control unit 43 is reset, and the transistor 4
8 drive signal is reset. The transistor 48 is turned off, the relay 42 is turned off, and the switching contact 42e is connected to the terminal 42a.
Connect with. At this time, if the ignition switch 22 is closed, the calculation circuit 41 continues to operate, but if it is open, the operation is stopped.

Relay control when getting off the vehicle will be explained with reference to the time chart of FIG. When the ignition switch 22 is opened to exit the vehicle, the ignition signal falls. At this falling point, the exit flag in the relay control section 43 is set. Next, when the door is opened, the door switch 26 is turned on, and the AND of the rising signal of the door switch signal and the exit flag causes the transistor 4 to turn on.
Set the No. 8 drive signal. Transistor 48 is turned on, relay 42 is turned on, and switching contact 42c is connected to terminal 42b. Power is supplied to the calculation circuit 41, and the calculation circuit 4
1 operates according to the flowchart shown in Figure 8g6).

Step 5102 reads the flag in the relay control unit 43, Stella 7'S 115 determines whether the vehicle is getting off the vehicle, and Step 81
A calculation circuit 41 controls the operation when a vehicle of 16 or less gets off the vehicle. After rotating the seat to the left and returning it to its original position, proceed to step 5.
At step 121, the exit flag in the relay control unit 43 is reset, and the drive signal for the transistor 48 is reset. Transistor 48 is turned off, relay 42 is turned off, and switching contact 4 is turned off.
2e is connected to terminal 42a. At this time, since the ignition switch 22 is open, the calculation circuit 41 stops operating.

Next, the operation of the batch IJu amount detection section 49 will be explained. This plays an important role in the device shown in FIG. In other words, if the battery capacity is reduced and power is consumed by moving the seat 5 or the like before starting the engine, the battery capacity will further decrease and this may interfere with engine starting.

Therefore, when the battery capacity is reduced, the detecting section 49 detects a decrease in the battery capacity and sends the result to the calculation circuit 41, and when the battery capacity decreases, movement of the seat, etc. is prohibited before starting the engine.

As a specific method for detecting capacity reduction, since a lead-acid battery is used as the battery in this embodiment, a method is used to measure the specific gravity of the electrolyte (for example, Japanese Patent Laid-Open No. 52-8123).
reference). The battery capacity can be detected by measuring the voltage drop when a large amount of power is consumed instantaneously (for example, see Japanese Patent Laid-Open No. 89220/1983).

The detailed operation of the entire system will be explained below with reference to the flowchart of FIG. When power is supplied to the calculation circuit 411C, initialization is first performed in step 5101. Power is supplied to the calculation circuit 41 when the relay 42 is turned on when the door is unlocked and opened when getting into the car, when the relay 42 is turned on when the ignition is turned off and the door is opened when getting off the car, and when the relay 42 is turned on when the door is opened after the ignition is turned off when getting off the car. Since there are three cases in which the switch 22 is closed, the flag is read in step 5102 and used as a basis for determining which of the calculation circuits 41 should be activated, that is, what the calculation circuit 41 should control.

When the Stella fs 103 determines that the boarding flag is set, control at the time of boarding is performed from step 8104. Step 5104 reads the value of the specific gravity sensor of the battery electrolyte and estimates the capacity of the battery (for example, see Japanese Patent Laid-Open No. 52-8123). In step 5105, if the battery capacity is greater than the specified value or there is no problem in starting the engine even if the foot seat 5 and the like are moved and the power is consumed, a series of operations are performed from Stella 7° 5107 for the passenger to board the vehicle. . On the other hand, if the battery capacity is less than the specified value, the process waits until the engine is started in step 5106, and after the engine is started, the seat, equipment, etc. are moved to the target position corresponding to the key signal from step 5111.

Next, the operation when the battery capacity is greater than the specified value will be explained from step 5107. First, in step 5107, a group of relays 44 is set to energize the seat slide motor in order to move the seat 5 rearward in order to facilitate boarding.
control. The motor rotates and the seat 5 moves rearward. A limit switch 505 for detecting the rearmost position of the seat slide is attached to the pace 508 fixed to the vehicle body.

In step 5107, the state of the limit switch 505 is monitored and the operating plate 506 is set to limit 2 or 5.
When it is detected that the switch is closed by pressing 05, the relay group 44 is controlled to stop energizing the slide motor.

Next, in step 8108, the motor for rotating the seat.

A group of relays 44 is controlled so that the K seat is energized to rotate toward the door, that is, to the right. The motor rotates and seats 5
rotates to the right. A limit switch 502 is installed to detect the right rotation limit (full right) of seat rotation. Step 8108 monitors the state of this limit switch 502), and the operating plate 503 is connected to the limit switch 50.
When it is detected that the switch is closed by pressing 2, the group of relays 44 is controlled to stop the energization of the rotary motor.

Seating switch 50 that detects that an occupant is sitting on the seat
4 is the installation. The state of this seat switch 504 is monitored in step 5109), and the operating plate 511 is
When it detects that the switch is closed by pressing 4, it moves to the next step. In step 5ilo, the K relay group 44 is controlled so that the seat rotation motor is energized to rotate the seat 5 to the left. The motor rotates and the seat 5 rotates to the left.

A limit switch 501 that detects whether the seat 5 is facing forward is attached. Stella fS 110 monitors the state of this limit switch 501.
When the actuating plate 503 detects that the switch 501 is closed, a group of relays 4 is configured to stop energizing the rotation motor.
Control 4.

The above is a series of controls to make riding easier.

From the next step, control is performed to automatically move to the stored position. In FIG. 3, numeral 47 is a key signal holding section that sets and holds the signal of the key sensor 24 when the door is unlocked.

The signal is held until the door is unlocked with a different type of key. In step 5111, the key signal of this hold section 47 is read.

In step 5112, the memory position to which each actuator should be moved is read from the memory unit corresponding to key types A, B, and CIC, and compared with the current position of each actuator, and the motor energization direction is determined to control the relay group 44. do. When the stored position and the current position become the same, the relay group 44 is controlled to stop energizing the corresponding motor. When automatic movement to the storage position is completed for all motors, the boarding flag in the relay control unit 43 is reset in step 5113, and then the relay 42 is turned off in step 5114.

By turning off the relay 102, the power to the wide calculation circuit 41 is cut off, and the calculation circuit 41 stops operating. The above is a series of controls when riding the IT.

Next, control when getting off the vehicle will be explained. If it is determined in step 5115 that the exit flag is set, control for exiting the vehicle is performed below. First, in step 8116, the current position of each actuator is stored in the storage unit corresponding to the type of key used.

Next, control is performed to make it easier to get off the vehicle.

This is almost the same control as the control that makes it easier to get on the vehicle.

In step 5117, the last limit switch 50
Retract the seat until 5 is turned on.

In step 5118, the seat is rotated clockwise until the limit switch 502 for clockwise rotation limit (full right) is turned on. In step 5119, the state of the seating switch 504 is monitored, and when it is detected that the switch 504 is turned off, the process moves to the next step.

In step 5120, the front limit switch knob 5
At step 121, the exit flag in the relay control section 43 is reset, and then at step 5122, the relay 42 is turned off. By turning off the relay 42, the power to the calculation circuit 41 is cut off, and the calculation circuit 41 stops operating. The above is a series of controls when getting off the vehicle.

Next, we will explain how to adjust to your optimum position using the manual operation switch. Manual operation is possible only when the ignition switch 22 is closed. When the Stella 7'5123 detects that the switch 22 is closed, the Stella fS124 reads the signals from the manual operation switch group 27.

If it is detected in step 5125 that any one of the switch groups 27 is turned on, the motor corresponding to the switch operation and its energization direction are determined, and in step 8126 the relay group 44 is controlled to energize the motor. In step 5127, the signals of the switch group 27 are read again, and in step 512
Stella 7'5 to see if it is the same as the switch read in step 4.
128 to judge. As long as you are operating the same switch,
Stella 7' 5127 and 5128 are repeated, so the corresponding motor continues to rotate. Step 5 when the switch is opened
At step 129, the relay group 44 is controlled to turn off the image motor. Then, the process returns to step 5L02 and waits for a new manual operation switch to be operated. When none of the switch group 27 is operated, Stella 7°510
2,5103°8115.5123.5124,812
5 and 5102, the calculation circuit 41 waits for switch input.

In the device shown in Figure 1, the battery capacity is checked and if it is below the specified value, the movement of seats, equipment, etc. is stopped until the engine is started and the generator starts generating electricity, and the battery capacity is further reduced. This is to prevent the engine startability from being affected by the operation of automatic restoring devices for passenger seats, equipment, etc., such as the engine not starting.

Effects of the Invention According to the present invention, a decrease in battery capacity is detected by the power supply control unit, and when a decrease in battery capacity is detected, the operation of key switches for seats, mirrors, etc. when turned off is stopped, the engine is started, and the generator is activated. Seats, mirrors, etc. can be set in the specified positions after confirming that power generation has started, and even if the battery capacity is low, there will be no problem with starting the engine, and passenger seats and equipment in the vehicle can be set. etc. can be appropriately controlled.
