Next, the operation of an embodiment of the present invention configured as described above will be explained. First, when the driver operates the transmission switch llb of the key 11 from outside the vehicle toward the receiver 31 on the door, an infrared signal unique to the key is transmitted from the light emitting element 11e. This infrared signal is received by the light receiving element 31B, converted into a digital signal, and outputted to the keyless ECU 12 as a keyless code. Then, in this keyless ECU 12, as shown in the flowchart of FIG. 13, it is determined whether the manually entered keyless code is the keyless code of driver A or the keyless code of driver B (step AI, A2).

If it is determined that the input keyless code is the keyless code of driver A or driver B, a matching signal is output to the door ECU 13. This match signal also includes an identifier indicating which driver's keyless code matches, driver A or driver B.

When the above coincidence signal is output to the door ECU1B, the door E
The CU 13 detects the state of the lock switch 133, and if the door is locked, drives the motor I3 to unlock the driver's side door, and if the door is unlocked, drives the motor m3. Lock the driver's side door. Then, data including an identifier indicating whether the driver's side door was locked or unlocked by keyless entry and an identifier indicating which driver locked or unlocked the door (hereinafter referred to as position number). The frames are multiplexed and transmitted to each ECU 15 to 18 via the serial data line D1.

Then, all doors are unlocked by the door ECU 13. For example, taking as an example a case where door unlocking processing is performed by door E CU 1.3, subsequent processing will be described with reference to the flowchart of FIG. 14.

The flowchart in FIG. 14 shows the overall flow of processing performed by each ECU 13.15-18 after all doors have been unlocked. After the doors are unlocked by the door ECUs 13 and 18 (step Bl), each ECU 13
．． 15 to 18 determine the contents of the data frame and determine whether the door has been unlocked by keyless entry (
Step B2). If it is determined in this determination that the door has been unlocked by keyless entry, a regeneration operation of the boarding/exiting position is performed (step B3), the detailed operation of which will be described later with reference to FIG.

This entry/exit position means the position of the driving equipment suitable for the driver to get on and off.The seat 21 is moved back slightly (for example, about 501I1m) from the driving position suitable for driving, and the steering wheel 22 is placed in the highest position. This means the position tilted up to. In addition, in this regeneration operation of the boarding/exiting position, the positions of other driving equipment are adjusted assuming that the seat is in the driving position.

Next, when the switch IGSWI detects that the ignition key is inserted into the key cylinder (step B4), a drive position regeneration operation is performed, the detailed operation of which will be described later with reference to FIG. Step B5). By regenerating the drive position, the seat 21 is slid slightly forward from the ingress/egress position, and the steering wheel 22 is tilted from the uppermost position to a driving position suitable for driving.

Next, when the ignition key is turned on, the switch I
When detected by GSV2 (step B6), the 17th
A standard setting operation, the detailed operation of which will be described later with reference to the figure, is performed (step B7).

This standard setting operation means that when the driver inserts the ignition key into the key cylinder after getting into the car, the seat 21 is moved to the driving position, but if this driving position does not suit the driver, the driver moves the seat 21 back and forth. This means that when the seat 21 is slid, the positions of other driving equipment are also automatically moved to positions that match the sliding position of the seat 21. Step B above
When adjusting the position of the driving equipment adjusted by the standard setting operation performed in step 7 to another position, operate the manual switch that adjusts the position of each driving equipment to adjust the position of the driving equipment. (Step B
8). When storing the position of the operating equipment adjusted by manual operation, it is performed by memory storage operation, the detailed operation of which will be described later with reference to FIG.
Step B10). That is, after adjusting the position of the driving equipment using the manual switch, it is possible to store the position by operating a predetermined key on the operation unit 19.

Next, the position of the driving equipment stored in step B9 can be reproduced by operating a predetermined key from the operation section 19. Such memory reproducing operation is performed in step BIO, and its detailed operation will be described later with reference to FIG. 21.

Next, for example, when the driver tilts the seat 21 while driving on a highway so as to make it easier to drive at high speed, the position of the driver's eyes changes. Therefore, the positions of the rearview mirror 20 and the outside mirror 14.2B are no longer optimal.

Therefore, in step Bll, the angles of the outside mirror 14, 23 and the rearview mirror 20 are corrected according to the amount of change Δe of the reclining angle e of the seat 21. The mirror correction interlocking operation performed in step B11 will be described later with reference to FIG.

As described above, the position of the driving equipment is adjusted to an appropriate position, and the driver is able to drive in the best driving environment. Then, when the driver finishes driving and turns off the ignition to exit the vehicle (step B12),
In each ECU, the position of the driving equipment is temporarily stored in a temporary memory (step B13). In other words, the driving position is stored in the -time memory. Next, when the driver tries to get out of the car and the ignition key is removed from the key cylinder, this key removal occurs on the host computer.
CU]5 is detected by switch IGSWI (Step B] 4). Then, the host ECU 15 sends a signal to the seat ECUI via the serial data line D1 to move the seat 21 and the steering wheel 22 to positions suitable for getting on and off.
6 and tilt ECUI 7. As a result, an easy access operation, the detailed operation of which will be described later with reference to FIG. 25, is performed, and the seat 21 is slid slightly rearward from the driving position.
The steering wheel 22 is tilted to the highest position (step B15). When the door is locked after the driver exits the vehicle, the locking of the door is detected by the lock switch 133, and in step 813, a memory operation is performed to memorize the driving position stored in the temporary memory of each ECU. (Step B16). This storage operation will be described in detail later with reference to FIG. 25.

By the way, the battery voltage Vt is input to the seat ECU 16, and the battery voltage Vt is input to the seat ECU 16.
If a sudden drop in the battery is detected, it is determined that the battery has been removed, and the sheet data stored in the memory 16e is
6e (step 818.B19). This memory saving operation will be described later with reference to FIG. 27.

The operation of this device from the time when the driver unlocks the door and gets into the vehicle through the series of processes described above until the driver gets out of the vehicle and locks the door has been schematically explained. Each detailed operation will be explained below.

Getting on/off position regeneration operation (step B3)>Each ECU
extracts the position number from the data frame multiplexed from the door ECU 13 via the serial data line D1 and writes the position number in each discrimination memory (step CI).

Then, in each ECU, it is determined whether the position number reproduced last and the position number unlocked by keyless entry this time match (step C2). If it is determined in step C1 that they "match," it is determined whether the position adjustment motor has moved after the last time the position of the driving equipment was reproduced (step C1).
B). If it is determined in step C3 that the vehicle has moved, each ECU performs a regeneration operation of the driving equipment position in the subsequent processing. In other words, door ECU13
The position of the door mirror 14 is reproduced based on the position data stored in the area designated by the position number stored in the discrimination memory 13a of the memory 13e (steps C4 and C5).

Furthermore, the position of the rearview mirror 20 is reproduced based on the position data stored in the area designated by the position number stored in the discrimination memory 15a of the host ECUI 5 (step C6). Furthermore, seat ECUI 6
Hide, tilt, and recline of the seat 21 are reproduced based on the position data stored in the area designated by the position number stored in the discrimination memory 16a (step C7). Then, the slide position of the seat 21 is adjusted by adding, for example, 50 mm to the slide position stored in the memory 16e, and the slide position of the seat 21 is adjusted to that position (step C8). In this way, the sheet 21 is formed as shown in FIG. 5(A).
As shown in the figure, it is slid 50 degrees back from the driving position, making it easier for the driver to get into the vehicle.

By the way, if rNOJ is determined in step C2 above, that is, if a different driver than last time gets on board, such as when driver A got on board last time and driver B gets on this time, the position of each driving equipment is Since it is necessary to make adjustments again, the process proceeds to step C4 and subsequent steps, and the positions of each driving equipment are regenerated.

In addition, if rNOJ is determined in step C3 above, that is, the same driver as last time gets on board, such as driver A got on board last time and driver A gets on board this time, and the position of the driving equipment is not reproduced last time. If the position adjustment motor has not been driven since then, there is no need to regenerate the position of the driving equipment, so proceed with step C4 above.
The playback operations of ~C8 are skipped. For example, sheet 2
When the motor l116 that controls the slide position of the seat ECU 16 is driven to control the hide position based on the position data stored in the memory 16e, since the seat 21 has inertia, the seat ECU 16 is Even after the stop signal is output to the stop signal 16, the seat 21 moves somewhat. In other words, since overshoot occurs, there is a problem that hunting occurs before the position control is finished, but as mentioned above, when the same driver as last time gets on board, the position of the driving equipment is regenerated from the previous time, and then the position If the adjustment motor is not driven, there is no need to regenerate, so hunting during regeneration is prevented by skipping the regeneration processing in steps C4 to C8.

Regeneration operation of the drive position (step B5)> When the switch IGSWI detects that the ignition key is inserted into the key cylinder, the host ECU1
5 instructs the seat ECU 16 and tilt ECU 17 to reproduce the driving position via the serial data line D1. As a result, the control shown in FIG. 16 is performed, and as shown in FIG. 5(B), the seat ECU 16 slides the seat 21 forward by 50+am from the getting-on/off position set in step C8 (step D).
I). Also, under the control of the tilt ECU 17, the memory 1
7. The steering wheel 22 is tilted based on the tilt data stored in the area designated by the position number in e (step D2).

<Standard setting operation (Step B7)> In this standard setting operation, the driver presses the slide switch 16.
If you operate 1 to set the slide position of sheet 21,
A function that automatically adjusts the position of other driving equipment #I (room mirror, etc.) to an appropriate position. The operation will be described below with reference to the flowchart in FIG. 17. After the driver operates the slide switch 161 to adjust the slide position of the seat 21 (step El), the operation section 1
9r 5TANDARD (standard setting) key 19b
, the host ECUI 5 judges the operation (step E2), and judges whether the shift position detected by the inhibitor switch 154 is "rP (parking)" (step E2a), if the shift position is rP.
If the vehicle speed is J, it is determined whether the vehicle speed V detected by the vehicle speed sensor 150 is less than or equal to a predetermined vehicle speed (for example, 3 km/h) (step E2b). In other words, this determination determines whether the vehicle is stopped. If it is determined in step E2b that the vehicle is stopped, the fact that the standard setting has been designated is multiplex transmitted to other ECUs via the serial data line D1. Seat ECU 16 that received this command
reads the slide position of the seat 21 from the memory 16b, estimates the driver's physique (standard sitting height, arm length, etc.) based on a map (not shown), and calculates the driver's shoulder position (x2°y2) as shown in FIG. ) (Step E
3). Next, the front hide amount, rear hide amount, and reclining angle for the slide position are determined with reference to the map in FIG. 32, and the front hide, rear hide, and reclining of the seat are adjusted based on the capacity.
Step E4). Next, the above shoulder position It(x2.y2
) and the reclining angle of the seat 21 determined in step E4 above, the tilt amount of the steering wheel 22 is set. Based on this tilt amount, the tilt ECU 17 controls the tilt of the steering wheel 22 (step E5).
. Next, a map (not shown) is referred to based on the standard sitting height of the driver's physique estimated in step E3, the seat recline amount and the seat rear hide amount determined in step E4, and the driver's eye position y3 is
(Fig. 31) is determined. Further, based on the seat slide position, standard sitting height, and seat recline amount, a not-shown mat is referred to and the eye position x3 is determined (step E6). In this way, the eye position (x3
．． y3) is determined. Next, the horizontal angle eh of the rearview mirror 20 is determined from a map (not shown) based on zl (fixed value) and x3, and the vertical angle ev is determined based on y3. y
4. The determination is made based on x3 with reference to a map (not shown). Then, the position of the rear-view mirror 20 is controlled by the host ECUI 5 so that the horizontal direction angle eh and vertical direction angle ev are the determined horizontal direction angle eh and vertical direction angle ev.
). Also, the horizontal angle Dx of the outside mirrors 14 and 23.

Dx' The vertical angles Dy and Dy' are determined from a map (not shown) based on the eye position (x3, y3) determined by the steering knob E6. And door ECU
The positions of outside mirrors 14 and 23 are controlled under the control of mirrors 13 and 18 (step E8).

In this way, once the seat slide amount is determined, the positions of all other driving equipment are automatically adjusted.
The driver does not have to adjust the position of each driving equipment individually, which simplifies the operation.

Manual Operation (Step B8)> The position of each driving equipment can be adjusted individually by the driver operating a manual switch.

First, manual operation of the outside mirror 14 will be explained. When the driver operates the manual switch 13, the door ECU 1.3 determines the operating direction (left, right) of the manual switch 31, and rotates the motor 12 forward or reverse while the manual switch 131 is operated. is under control. As a result, the outside mirror 14 is controlled to rotate left and right. The horizontal angle of the outside mirror 14 is detected by the Hall element 135, converted into a voltage signal according to the horizontal angle, and sent to the door ECUI 3. This door ECU 13 converts the voltage signal into a digital quantity and stores it in the memory 13b as a horizontal direction angle Dx.

Similarly, when the driver operates the manual switch 132, the direction of operation (up or down) is determined by the door ECUI 3, and while the manual switch 132 is operated, the motor 1 is controlled to rotate forward or reverse, and the outside mirror 14 is rotated. rotated upward or downward. The vertical angle of the outside mirror is determined by the Hall element 13.
4 is detected, converted into a voltage signal according to the vertical angle, and sent to the door ECU 13. This door ECUI
3 converts the voltage signal into a digital quantity and stores it in the memory 13b.
is stored as a vertical angle Dy. In this way,
Operate manual switch 131 or 132,
When the position of the outside mirror 14 is adjusted, its position data (vertical angle Dy and horizontal angle Dx) is stored in the memory 13b.

Next, manual operation of the rearview mirror 20 will be explained. When the driver operates the manual switch 151, the host ECU 15 determines the operating direction (left, right) of the manual switch 151, and
While the motor 1 is being operated, the motor 15 is controlled to rotate forward or reverse. As a result, the rearview mirror 20 is controlled to rotate left and right. The horizontal angle of the rearview mirror 14 is detected by the Hall element 154, converted into a voltage signal according to the horizontal angle, and sent to the host ECU 15. This host ECU 15 converts the voltage signal into a digital quantity and stores it in the memory 15b as a horizontal direction angle eh.

Similarly, when the driver operates the manual switch] 52, the direction of the operation (up or down) is determined by the host ECU 15, and while the manual switch 152 is operated, the motor ta4 is controlled to rotate forward or reverse, and the rearview mirror 20 is moved upward. Or it is rotated downward. The vertical angle of the rearview mirror is detected by the Hall element 153, converted into a voltage signal according to the vertical angle, and sent to the host ECU 15. The host ECUI 5 converts the voltage signal into a digital quantity and stores it in the memory 15b as a vertical angle eh. In this way, when the position of the rearview mirror 20 is adjusted by operating the manual switch 151 or 152, the position data (vertical direction angle Sv and horizontal direction angle eh) is stored in the memory 15b.
is memorized.

Next, manual operation of the seat 21 will be explained.

As described above, the posture of the seat 21 is controlled by four motors.

First, when the slide switch 161 of the seat 21 is operated, the direction of operation (front, rear) is determined by the seat ECU 16, and while the slide switch 161 is operated, the motor I6 is controlled to rotate forward or reverse, and the seat 21 is rotated forward or backward. be slid in the direction. When the motor IB is rotated, a number of pulses corresponding to the rotation angle are sent to the rotation sensor 1.
65 to the seat ECU 16. The seat ECU 16 increments the slide counter C1 by "+1" each time one pulse is input from the rotation sensor 16. Here, the slide counter C1 is reset in response to a signal from the limit switch LSW1, which is opened when the seat 2] is at the frontmost position. In other words, the count value of the slide counter C1 means a value corresponding to the slide position of the sheet 21. In this way, when the motor is rotated, a pulse is manually applied to the seat ECU 16 to update the count value of the slide counter C1, but when the slide switch 161 is returned to the neutral position, the operation is
It is detected by U16 and a stop signal is output to motor 1B. In response to this stop signal, the process shown in FIG. 27 is performed. First, the counting operation of the 100w5ec timer is started (step Fl). Next, the pulses output from the rotation sensor 165 are read into the seat ECU 16,
Slide counter C1 is updated (step F2).

Then, it is determined whether roomsec has been counted by the 100m5ec timer (step F3), and if it has not been counted yet, reading of pulses is continued. When 100g5ec is counted by the 100m5ec timer, reading of pulses from the rotation sensor 165 is prohibited (step F4). Then, considering the count value counted by the slide counter C1 and the rotation direction of the motor 6 before stopping, the slide position W (absolute value) stored in the memory 16b is set to a slide position corresponding to the count value. is added or subtracted. That is, if the rotation of the motor 16 before stopping is in the direction of moving the seat 21 backward, it is added, and if it is in the direction of moving the seat 21 forward, it is subtracted.

Since the seat 21 has been moved by inertia force since the stop signal was output to the motor 1B, the rotation sensor 165 is
The slide counter C1 is updated by pulses output from the slide counter C1. This means that the stop signal is motor 1
When the pulse outputted from the rotation sensor 165 is prohibited from being inputted to the seat ECU 16 immediately after being outputted to the rotation sensor 16, the above-mentioned stop signal is outputted to the slide counter C1, which corresponds to the amount by which the seat 21 has moved due to inertia. This is because there is a problem in that the pulses are not manually applied and the count value of the slide counter C1 does not correspond to the amount of movement of the sheet 21.

The process of the seat ECU 16 in response to the operation of the switches 162 to 164 that are operated when adjusting the front hide, rear hide, and recline of the seat 21 is the same as the process in response to the operation of the slide switch 161 described above, The pulses from counters C2 to C
It is counted by 4. Then, the respective movement amounts of the front hide, rear hide, and reclining angle are calculated from the counted values of the counters C2 to C4, and the same calculation as when calculating the slide position (absolute value) of the seat 21 as described above is performed. The front hide Hf, rear hide Hr, and reclining angle e are stored in the memory 16b as absolute values.

Next, the operation of manually adjusting the tilt angle Te of the steering wheel 22 will be described. First, switch 1
When you operate 71, the operation direction (front, rear) will change to tilt E.
This is determined by the CU 17, and while the switch 161 is operated, the motor 1o is controlled to rotate forward or reverse, and the tilt angle Te of the steering wheel 22 is increased or decreased. and,
The tilt angle detected by the potentiometer 172 is A/D converted in the tilt ECUI 7 and then the memory 17
b.

Memory storage operation (step B9)> This memory storage operation is an operation for storing the position of driving equipment. In other words, r of the operation section 19) IEMORYJ
After operating the key 19a, by operating the "1" key to "3" key 191 to 193 to specify the memory number, the current position of the driving equipment is stored in the area specified by the memory number in the memory of each ECU. The data is stored respectively.

Since the memory numbers range from "1" to "3", each ECU can store three types of position data. The operation will be described in detail below with reference to the flowcharts shown in FIGS. 18 to 20.

First, after operating the rME)IORYJ key on the operation unit 19, a memory number is entered manually, and the host ECU 15 detects the series of operations. As a result, the host ECUI 5 connects to the other ECUI via the serial data line D1.
Frame data having a memory storage command and a memory number as control data is multiplex transmitted to U. The ECU that has received this frame data determines that there has been a memory storage operation (step Gl), and determines the memory number from the control data (step G2). First, host ECU1
5 stores the room mirror data stored in the memory 15b in the area designated by the memory number of the memory 15e (step G3).

The storage operation of the rearview mirror position will be explained below with reference to the flowchart of FIG. 19. First, it is determined whether the position number reproduced last and the memory number to be stored this time match (step H1). If it is determined in step H1 that they match,
After the last memory reproduction, it is determined whether the position adjustment motor has moved (step H2). If it is determined in step H2 that it has moved, then the memory 15b
Processing for storing the position data (horizontal direction angle eh, vertical direction angle eV) of the rearview mirror 20 stored in is performed in steps H3 to H5.

First, it is determined whether the position data is within a storage range (memory limit range) that can be stored in the memory 15c (step H3). If the determination in step H3 is rYESJ, the position data stored in the memory 15b is stored in the area designated by the memory number of the memory 15c. On the other hand, in step H3 above, rN
If OJ is determined, a memory limit position as shown in FIG. 34 is stored.

In this manner, when the position data exceeds the memory limit range, the memory limit position is stored, thereby preventing the storage of position data larger than the memory limit position.

If the vicinity of the manual adjustment limit position is stored in the memory 15c, the rearview mirror 20 may become unlinked during playback, making playback impossible.

However, if the position data exceeds the memory limit range, the memory limit position is stored, so that playback can be ensured.

If the determination in step H1 is "NO", the process moves to step H3, and in step H2, rN
If it is determined to be OJ, the storage operations performed in steps H4 and H5 are skipped. In other words, if the position number played last time and the memory number to be stored this time are the same, and it is determined that the rearview mirror 20 has not been manually moved between the time it was played last time and the time it is stored this time, the position number will be the same again. Since there is no need to store position data, the storage operation is skipped.

Therefore, the state in which the position data used during the previous reproduction is stored in the area designated by the memory number of the memory 15c is maintained. By doing this, even if the position is overrun and stopped due to the inertial force of the rearview mirror 20 during the previous playback,
, the overrun position data is stored in the memory 15b.
Since the position data is not read from the memory 15g and stored in the area specified by the memory number of the memory 15g, accurate position data can be held in the area specified by the memory number of the memory 15c.

Next, the door ECU 13 stores the outside mirror data stored in the memory 13b in the area designated by the memory number of the memory 13c (step G4). Processing similar to that shown in the flowchart in the figure is performed.

This prevents the link between the male screw 31 and the actuator 33 from coming off during regeneration, making regeneration impossible.

Further, the tilt ECU 17 stores the tilt data stored in the memory 17b in the area designated by the memory number of the memory 17c (step G5).

Furthermore, the seat position is stored by the seat ECU 16 (step G6), and its detailed operation will be described below with reference to the flowchart in FIG. 20.

In FIG. 20, it is determined whether the position number reproduced last and the memory number to be stored this time match (step II). If it is determined in step 11 that they match, it is determined whether the position adjustment motor has moved after the last memory replay (
Step I2). Next, the angle (memory limit position) β at which the seat 21 can be tilted is calculated from the slide amount X stored in the memory 16b (β-f (x) 10a) (step I3). According to the above formula, the angle β is set to an angle that does not cause the seat 21 to come into contact with the person sitting in the rear seat. Then, it is determined whether the reclining angle α of the seat 21 stored in the memory 16b is less than or equal to the memory limit position β, and rY
If it is determined to be ESJ, the current position α is stored and r
If NOJ, the memory limit position β is stored (steps 4 to 16). Note that the positional relationship between α and β is shown in FIG.

In this manner, when the position data exceeds the memory limit range, the memory limit position is stored, thereby preventing the storage of position data larger than the memory limit position.

In this way, the memory limit position β of the seat 21 is determined according to the sliding position of the seat 21, so the reclining angle e that does not disturb the people sitting in the rear seat can be reliably determined according to the sliding position of the seat 21. The safety of the device can be sufficiently ensured. Also,
Since the memory limit position β is detected based on the relative position from the limit switch LSW4, there is no need to provide a switch specifically for detecting the position corresponding to the memory limit position, so the device can be simplified.

Memory regeneration operation (step BIO)> This memory regeneration operation is an operation for regenerating the position of the driving equipment stored in the process of step B9 above.For detailed operation, see FIGS. 21 to 23. and explain. When a memory number is designated by operating the "1" key to "3" keys 191 to 193 of the operation unit 19, the host ECUI 5 detects the operation. As a result, the host ECU 15 connects to other ECs via the serial data line D1.
Frame data having a memory reproduction command and a memory number to be reproduced as control data is multiplex transmitted to U. The ECU that has received this frame data determines that a memory regeneration operation has been performed (step J1), and determines the memory number from the control data (step J2). Then, it is determined whether the shift position detected by the inhibitor switch 154 is "rP (parking)" (step N1), and if the shift position is rPJ, the vehicle speed detected by the vehicle speed sensor 150 is set to a predetermined vehicle speed (for example, 3 k
m/h) or less (step N2). In other words, this determination determines whether the vehicle is stopped. If it is determined in step N2 that the vehicle is stopped, the host ECU 15 adjusts the rearview mirror 20 based on the rearview mirror data stored in the area designated by the memory number of the memory 15c. The position is reproduced (step J3). The reproducing operation of the room mirror 20 will be explained with reference to the flowchart of FIG. 22.

In FIG. 21, it is determined whether the position number reproduced last and the memory number operated this time match (step Kl). If it is determined in step 1 that they match, it is determined whether the position adjustment motor has moved after the last position reproduction (step 2).

If it is determined in step 2 that it has moved, the horizontal position data to be reproduced is substituted into the current position of the rearview mirror stored in the memory 15c (
Step 3). In other words, as shown in FIG. 36, when the current position is (xi, yl) and the return position to be reproduced is (x2.y2), it is an operation to obtain (x2, 71).

Then, it is determined whether (x2.yl) is within the operable range (step 4). In other words, (x2゜yl) is the third
It is determined whether it is within the circle in Figure 6.

Here, if it is determined that j is within the operable range, the motor 15 is first driven so that the horizontal angle of the rearview mirror 20 becomes equal to the horizontal angle eh stored in the memory 15c. (step 5).Next, the motor I4 is driven to automatically adjust the vertical angle of the rearview mirror 20 to be equal to the vertical angle ev stored in the memory 15c (step 5). Step 6).On the other hand, if rNOJ is determined in step 4, the order of automatic adjustment is reversed, the motor 4 is driven, and the vertical angle ev of the rearview mirror 20 is set to the vertical angle ev of the memory 15C. After the horizontal direction angle of the rearview mirror 20 is automatically adjusted to be equal to the direction angle, the motor 5 is driven and the horizontal direction angle of the rearview mirror 20 is set to the memory 1.
．． It is automatically adjusted to be equal to the horizontal angle eh stored in 5c (step 9).

In this way, when reproducing the position of the rearview mirror 20, if the horizontal angle is within a range where the motor gi5 cannot operate, the motor I4 is driven to adjust the vertical angle, and then the horizontal angle is adjusted. By doing so, even if the horizontal direction angle of the playback position deviates from the circle shown in FIG. 36, it is possible to reliably return to the playback position. Furthermore, by adjusting the angle in the other direction after completing the adjustment of the angle in one direction, it is possible to prevent hunting during the reproducing operation. In other words, when reproducing the position of the rear-view mirror 20, for example, if motor 4 is adjusted to adjust the vertical angle, this adjustment will cause the rear-view mirror 20 to
The horizontal angle also varies slightly. Therefore, if the vertical angle of the room mirror 20 is adjusted after adjusting the horizontal angle, the initially adjusted horizontal angle changes slightly and becomes no longer equal to the data stored in the memory 15C. In this case, if the horizontal adjustment is performed again, the rearview mirror 20 will hunt.

In order to prevent this hunting, the playback operation is considered complete when the angle in one direction is adjusted and then the angle in the other direction is adjusted.

Next, the door ECU 13 reads the outside mirror data stored in the area specified by the memory number of the memory 13c, and determines the position of the outside mirror 14 under the same control as in the flowchart shown in FIG. It is played back (step J4).

Next, the tilt ECUI 7 reads the tilt data stored in the area designated by the memory number of the memory 17c, and drives the motor mlO so that the data becomes equal to the current tilt data stored in the memory 17b. In this way, the tilt of the steering wheel 22 is reproduced (step J5).

Next, the position of the sheet 21 is reproduced, and the detailed operation will be described below with reference to FIG. 23. Second
In FIG. 3, it is determined whether the position number reproduced last and the memory number operated this time match (step Ll). If it is determined that they match in step L1, after playing the last position,
It is determined whether the position adjustment motor has moved (step L2). If it is determined in step L2 that the seat has moved, the sliding position, front tilt, rear tilt, and reclining angle of the seat 16 are stored in the area specified by the memory number in the memory 16c. Driving of the motors 1B to 19 is started so that the sheet data becomes equal to the sheet data (step L3). Hereinafter, for the sake of simplicity, a case will be described in which the sliding position of the seat 21 is adjusted.

At step L3, the transistor Q1 shown in FIG. 12 is driven to start driving the motor 16 in normal rotation, and the timer T1 starts to measure time (step L4). This timer T1
The time elapsed since motor s8 was driven is counted. Then, it is determined whether the slide position of the sheet 21 has reached the playback position (step L5), and if the slide position of the sheet 21 has not reached the playback position, the timer T1 is counted up (step L6).

In the determination at step L5, if it is determined that the slide position of the sheet 21 has reached the playback position, the time counted by the timer T1 is T2 hours (for example, 1.00 hours).
ssec ) or less (step L7)
. If the determination in step L7 is rNOJ, and if it is determined that the slide position has been adjusted to the playback position after T2 hours or more after the motor s6 is driven, the transistor Q1 is turned off under the control of the seat ECU 16. Then, motor I6 is stopped (step L8).

On the other hand, if the determination in step L7 is YES, control is performed to turn on transistor Q2 (step L9).In this way, when either transistor Q1 or Q2 is turned on, the motor Since voltage V is applied across m6, rotation of motor IB is stopped.After time T2 has elapsed by timer T2, transistors Q] and Q2 are turned off (steps LIO, Lll).

With this configuration, in order to finely adjust the seat position, the transistor Q1 is turned on and the relay coil 5 is turned on.
11 i;: If the regeneration position is reached within JOOisec after the motor m16 is driven in normal rotation by applying current, the transistor Q2 is turned off without turning off the transistor Q1.
Since the motor m6 is stopped by turning on the relay coil 511 within 100i+sec.
It is possible to prevent the relay coil 511 from being destroyed by cutting off the current.

As described above, when a memory number is designated by key operation on the operation unit 19, the position of the driving equipment is reproduced under the control of each ECU.

Mirror correction interlocking operation (step B11)> What is this mirror correction interlocking? The standard setting operation in step B6 above, the manual operation in step B8, the memory storage operation in step B9, and the memory regeneration operation in step BIO have all been completed. This refers to an operation in which the positions of the room mirror 20 and the outside mirror 14, 23 are corrected in conjunction with each other according to the amount of change Δe in the reclining angle e when the seat 21 is reclined.

The mirror correction linkage will be explained below with reference to the flowchart of FIG. In FIG. 24, the operating section 19
Check whether the indicator that lights up when the rcancel J key 19c is operated is off or not in the host ECU 15.
Determined by.

The r cancel J key 1.9c is operated by the driver when he wants to cancel the mirror correction interlocking operation, and when he operates the r eaniel J key 19c, the indicator lights up. If "YES" is determined in this step Ml, since the mirror correction interlocking has not been canceled, the determinations in steps M2 to M4 are performed. If it is determined in steps M2 to M4 that the standard setting operation, memory reproduction operation, or memory storage operation has been completed, the process proceeds to step M5 and subsequent steps.

As explained in the configuration section, the seat ECU 16 sends the seat data and the amount of change Δe in reclining to the host ECU 15 via the seat data line D2. The host ECU 16 determines whether the amount Δe is equal to or greater than rOJ, and determines whether the reclining position of the seat 21 has changed (step M5). If it is determined in step M5 that the reclining has changed, it is determined whether the amount of change Δθ is between 30 and Δβ (step M6). Here, the reason why the lower limit value Δa is set for the amount of change Δe is that it is considered unnecessary to move the mirror in response to minute fluctuations in reclining the seat 21. If rYEsJ is determined in step M6, the position ife+ of the seat 21 before the reclining change and the position e2 after the change are "
α≦e3. It is determined whether the relationship “β≦e2” exists. If the determination in step M7 is rYESJ, the host ECU 15 adjusts the position of the rearview mirror 20 to α1.
(Step M8) Further, a mirror correction interlock start command is output from the host ECUI 5 to the door ECU 13, and an operation is performed to correct the outside mirror 14 by β (Step M9). As described above, the angles of the room mirror and the outside mirror are corrected according to the amount of change in the reclining of the seat 21.

By the way, in the above steps M2 to M4, r
If the determination is NOJ, the processing from step M5 onwards is skipped, so the mirror correction interlocking operation is not performed. Furthermore, if rNOJ is determined in the determinations in steps M5 to M7 above, step M8. Since the determination of M9 is skipped, the mirror correction interlocking operation is not performed.

<Easy access operation (Step B15)> In this easy access operation, when the ignition key is removed from the key cylinder, the driver exits the vehicle by moving the seat 21 back 50gg from the driving position and flipping the steering wheel 22 up to the highest position. An action that makes it easier to do something.

When the host ECU 15 detects that the ignition key is removed from the key cylinder based on a signal from the switch JGSW, the control shown in the flowchart of FIG. 25 is started. First, it is determined whether the shift position detected by the inhibitor switch 154 is "P (parking)" (step N1), and if the shift position is "P", the vehicle speed V detected by the vehicle speed sensor 150 is set to a predetermined vehicle speed (
For example, it is determined whether the speed is less than 3 km/h (step N2). In other words, this determination determines whether the vehicle is stopped. If it is determined in step N2 that the vehicle is stopped, the host ECU 15 multiplex transmits a data frame containing information for performing an easy access operation to the seat ECU 16 via the serial data line D1. .

Upon receiving this data frame, the seat ECU 16 reads the slide position (driving position) when the ignition switch is turned off from the position data stored in the temporary memory 16d in step B15, and moves the slide position back by 50 mm. so that
The rotation of motor I6 is controlled (step N3). When the host ECUI 5 detects that the driver's side door has been opened by a signal from the door switch Sochi DR3W, the host ECU 15 converts the data frame containing the information for performing the easy access operation to the tilt ECU 17 into serial data. multiplexed transmission via line D1. After receiving this frame data, the tilt ECU 22 controls the motor m.
The steering wheel 22 is tilted up to the highest position by driving IO (step N5). By the way, if rNOJ is determined in the above steps Nl, N2°N4, the easy access operation is not performed.

As described above, when it is detected that the driver is getting off the vehicle, the positions of the seat 21 and the steering wheel 22 are automatically moved to a position where the driver can easily get off the vehicle. 22 to a position where it is easy to get off the vehicle can be saved.

Drive position storage operation (Step B17)> This drive position storage operation stores the driving position of the driving equipment saved in the temporary memory of each ECU in the memory specified by the position number when it is detected that the door is locked. This refers to the action of remembering something. The seat and steering wheel positions are moved to a position where it is easy to get out of the car by the easy access operation in step B15, and when the driver gets out of the car and operates the key transmission switch 11b toward the receiver 31 on the door, the light emitting element 11e emits a key-specific message. An infrared signal is transmitted. This infrared signal is received by the light receiving element 31a, converted into a digital signal, and outputted to the keyless ECU 12 as a keyless code. Then, the keyless ECU 12 determines whether the inputted keyless code is the keyless code of driver A or the keyless code of driver B, as shown in FIG. 13 (step AI, A2). If it is determined that the manually entered keyless code is that of driver A or driver B, a matching signal is sent to door E.
It is output to the CU13. This match signal also includes an identification signal indicating that the keyless code matches the keyless code of either the A driver or the B driver and means t2.

When the above coincidence signal is output to the door ECU1B, the door E
The CU 13 detects the state of the lock switch 133 and, since the door is unlocked, drives the motor 113 to lock the driver's side door. The host ECUI 5 then uses an identifier indicating whether the driver's side door was locked by keyless entry and an identifier indicating which driver locked the door (hereinafter referred to as position number).
A data frame including the data frame is multiplexed and transmitted to each ECU 15 to 18 via the serial data line D1. Each ECU that receives this data frame first determines whether the door is locked by keyless entry operation (step PI). If the determination is rYESJ, the position number is determined from the received data frame (step P2). Then, in step 813 above,
The position data (driving position) of the driving equipment stored in the temporary memory of each ECU is stored together with the position number in the memory specified by the above position number (
Step P3) For example, in the case of the seat ECU 21, the driving position of the seat 21 stored in the - time memory 16d is stored in the area designated by the position number of the memory 16e. Then, the position number stored in the discrimination memory of each ECU is cleared (step P4).

On the other hand, if rNOJ is determined in step P], the processes from step P5 onwards are performed. First, if the door is locked by inserting the ignition key into the keyhole of the door or by operating the lock knob on the door without using the ignition key, proceed to Step C1 in Figure 15. The position data (driving position) of the driving equipment stored in the temporary memory is stored in the memory designated by the position number stored in the discrimination memory of the ECU. for example,
In the case of the seat ECU 21, the driving position of the seat 21 stored in the - time memory 16d is stored together with the position number in the area designated by the position number of the memory 16e. And the above step P4
Then, the position number stored in the discrimination memory is cleared.

In this way, the driving position of each driving equipment is automatically memorized not only when the door is locked, but also when the door is locked. In this way, when the driver exits the vehicle and the doors are locked, the driving position is automatically stored, so the driver does not have to perform an operation to store the driving position inside the vehicle before exiting the vehicle.

As a result, storage operations can be simplified.

Sheet data memory backup function> What is the sheet data memory backup function? When a sign that the battery is removed is detected, memory 1, which is volatile memory, is
This is a function to save the sheet data stored in the memory 6e to the save memory 16h, which is a non-volatile memory. As shown in FIG. 28, the seat ECU 16 detects the battery voltage Vt at every predetermined sampling time in step Q1.
), the battery voltage change rate ΔVt is calculated from the voltage Vt' detected during the previous sampling (step Q2
) Then, it is determined whether the sign of this rate of change ΔVt is negative (step Q3). rYE in this step Q3
If it is determined that sJ, it is determined that the battery voltage Vt is on a decreasing trend. Then, the process proceeds to the determination in step Q4, and it is determined that the battery voltage Vt is equal to or lower than the predetermined voltage v1 (step Q4). Then, in this step Q4, if it is determined that rYEsJ, Δ
It is determined whether the absolute value of Vt is greater than or equal to ΔV1 (step Q5). The determination in step Q5 is that since the rate of change ΔVt of the battery voltage that occurs when the battery is removed is large, it is determined whether the rate of change ΔVt is greater than or equal to a predetermined rate of change ΔV1, and it is detected that it is a sign of battery removal. are doing. Then, in this step Q5, r
If it is determined as YESJ, it is determined that the battery should be removed, and a transfer operation is automatically performed to transfer the sheet data stored in the memory 16e to the evacuation memory 16h).
This is performed under the control of the ECU 16 (step Q6).

On the other hand, in step Q3, if it is determined that rNOJ, it is determined that the battery voltage Vt is on an increasing trend. The process then proceeds to step Q7, where it is determined that the battery voltage Vt is equal to or higher than the predetermined voltage V2. If rYESJ is determined in step Q7, it is determined whether the absolute value of ΔVt is greater than or equal to ΔV2 (step Q8). Since the rate of change ΔVt of the battery voltage that occurs when the battery is attached is large, the determination in step Q8 is to determine whether the rate of change ΔVt is greater than a predetermined rate of change ΔV2, and to confirm that it is a sign that the battery will be attached. Detected.

In this step Q8, if it is determined as rYESJ, it is determined that the battery is installed, and the evacuation memory 1
The transfer operation to transfer the sheet data (absolute position) stored in memory 6h to memory 16e is automatically performed by the seat ECU.
16 (step Q9).

In this way, even if the battery is removed, the memory 1
The sheet data stored in 6e is saved in a nonvolatile memory, and when the battery is installed, the sheet data is automatically restored to the memory 16e, so even if the battery is removed, Memory 16e
The absolute seat position stored in can be continuously stored. As explained in the above configuration, the position of the sheet 21 is detected by counting the number of pulses from the position where the limit switch is opened, and calculating the absolute position based on the number of pulses. Therefore, if the absolute position of the seat stored in the memory 16e is erased by removing the battery, the absolute position of the seat can be adjusted by moving the seat, opening the limit switch, and then moving it to the drive position. memory 16e
It is possible to store it in However, as described above, even if the battery is removed, the seat absolute position stored in the memory 16e is automatically evacuated, thereby eliminating the need for the above-described operation.

The GSWI may also be connected to the seat ECU 16 and the tilt ECU 17.

In this case, the seat ECU 16 and the tilt ECU 17 can independently detect the inserted state of the ignition key without detecting the inserted state using the data frame transmitted from the host ECU 15. Therefore, in the drive position regeneration operation (step B5), the seat ECU 16 and tilt ECU 17 independently detect the insertion of the ignition key and perform the driving position regeneration without depending on the command from the host ECU 15. good.

Further, in the above embodiment, the switch IGSWI and the door switch DR8V are connected to the host ECUI 5, but the switches IGSv1 and DR8V may also be connected to the seat ECU 16 and the tilt ECU 17. In this case, the seat ECU
