Next, the operation of the embodiment of the present invention configured as described above will be described. First, when the driver operates the transmission switch 11b of the key 11 from outside the vehicle toward the receiver 31 of 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 31a and then converted into a digital signal, which is used as a keyless code as a keyless EC.
Output to U12. The keyless ECU 12 determines whether the input keyless code is the keyless code of the A driver or the keyless code of the B driver as shown in the flowchart of FIG. 13 (steps A1, A
2). When it is determined that the input keyless code is the keyless code of the A driver or the B driver, a coincidence signal is output to the door ECU 13. This match signal also includes an identifier indicating which of the driver A and the driver B matches the keyless code of the driver.

When the coincidence signal is output to the door ECU 13, the door ECU 13
Detects the state of the lock switch 133, drives the motor m3 to unlock the driver's seat side door if the door is locked, and drives the motor m3 if the door is unlocked to operate. Lock the seat door. Data including an identifier indicating whether the driver's seat side door has been locked or unlocked by the keyless entry and an identifier indicating which driver has locked or unlocked (hereinafter, referred to as a position number). The frame is multiplexed and transmitted to each of the ECUs 15 to 18 via the serial data line D1. Then, all the doors are unlocked by the door ECU 13. For example, taking the case where the door ECU 13 performs door unlocking processing as an example, the subsequent processing will be described with reference to the flowchart in FIG.

The flowchart in FIG. 14 shows the flow of the entire processing performed by the ECUs 13, 15 to 18 after all the doors are unlocked. After the doors are unlocked by the door ECUs 13 and 18 (step B1), the ECUs 13, 15 to 18 determine the contents of the data frame and determine whether the door is unlocked by keyless entry (step B2). ). If it is determined by this determination that the door has been unlocked by the keyless entry, a loading / unloading position reproducing operation, whose detailed operation will be described later with reference to FIG. 15, is performed (step B3). The getting on / off position means a position of driving equipment suitable for the driver to get on and off, and the seat 21 is slightly behind the driving position suitable for driving (for example, 50 mm).
), And the steering 22 means a position where the steering wheel 22 is tilted to the uppermost position. In addition, in the reproducing operation of the getting on / off position, the position of the other driving equipment is adjusted on the assumption that the position of the seat is at the driving position.

Next, the switch IGSW1 detects that the ignition key has been inserted into the key cylinder (step B
4), and a drive position reproducing operation whose detailed operation will be described later with reference to FIG. 16 is performed (step B).
Five). Due to the reproduction of the drive position, the seat 21 is slid slightly forward from the getting on / off position, and the steering 22 is tilted from the uppermost position to a driving position suitable for driving.

Next, the switch turns on when the ignition key is turned on.
When detected by IGSW2 (step B6), a standard setting operation whose detailed operation will be described later with reference to FIG. 17 is performed (step B7). This standard setting operation means that when the driver inserts the ignition key into the key cylinder after getting on, the seat 21 is moved to the driving position, but when this driving position is not suitable for the driver, the driver moves the seat 21 back and forth. , The position of the other driving equipment is automatically moved to a position that matches the sliding position of the seat 21.
When adjusting the position of the driving equipment adjusted by the standard setting operation performed in step B7 to another position, operate the manual switch that adjusts the position of each driving equipment and adjust the position of the driving equipment (Step B8). When the position of the driving equipment adjusted by the manual operation is stored, the detailed operation is performed by the memory storing operation described later with reference to FIG. 18 (step B10). That is, after adjusting the position of the driving equipment with the manual switch, it is possible to store the position by performing a predetermined key operation of the operation unit 19.

Next, the position of the driving equipment stored in step B9 can be reproduced by a predetermined key operation from the operation unit 19. Such a memory reproducing operation is performed in step B10, and its detailed operation will be described later with reference to FIG.

Next, for example, when the seat 21 is tilted so that the driver can easily move at high speed while driving on a highway, the position of the driver's eyes changes. For this reason, the room mirror
The positions of 20 and the outside mirrors 14, 23 are no longer optimal. For this reason, in step B11, the angles of the outside mirrors 14, 23 and the room mirror 20 are corrected according to the change amount ΔΘ of the reclining angle Θ 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 operates in the best driving environment. Then, when the driving by the driver is completed and the ignition is turned off to get off (step B12),
The position of the driving equipment in each ECU is temporarily stored in the temporary memory (step B13). That is, the driving position is stored in the temporary memory. Next,
When the driver tries to get off and the ignition key is removed from the key cylinder, the key is removed from the host ECU 15
This is detected by the switch IGSW1 (step B14). Then, the host ECU 15 sends a signal for moving the seat 21 and the steering wheel 22 to the entry / exit position suitable for getting on / off the serial data line.
The transmission is multiplexed to the seat ECU 16 and the tilt ECU 17 via D1. Thereby, an easy access operation, which will be described later in detail with reference to FIG. 25, is performed, the seat 21 is slid slightly behind the driving position, and the steering 22 is tilted to the uppermost position ( Step B15). Then, when the door is locked after the driver gets off the vehicle, the lock of the door is detected by the lock switch 133, and in step B13, a storage operation for storing the driving position stored in the temporary memory of each ECU is performed. (Step B16). This storage operation will be described later in detail with reference to FIG.

By the way, the battery voltage Vt is input to the seat ECU 16, and when a sudden decrease in the battery voltage Vt is detected in the seat ECU 16, it is determined that the battery is removed, and the memory
The sheet data stored in the memory 16e is saved in the memory 16e (steps B18 and B19). This memory saving operation will be described later with reference to FIG.

The operation of the present apparatus from the time when the driver unlocks the door and gets on the vehicle through the above series of processing to the time when the driver gets off and locks the door has been schematically described. Less than,
Each detailed operation will be described.

<Entrance / Reception Position Reproduction Operation (Step B3)> Each ECU extracts a position number from a data frame multiplexed and transmitted from the door ECU 13 via the serial data line D1, and writes the position number into each discrimination memory (step C1). . Then, in each ECU, it is determined whether the position number reproduced last and the position number unlocked by the current keyless entry match (step C2). If it is determined in step C1 that they match, it is determined whether the position adjustment motor has moved since the position of the driving equipment was reproduced last (step C3). In the judgment of step C3, "moved"
If it is determined that, each ECU executes the reproduction operation of the driving equipment position by the following processing. That is, the door ECU1
3, 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 (step C
4, C5). Further, the position of the room mirror 20 is reproduced based on the position data stored in the area specified by the position number stored in the determination memory 15a of the host ECU 15 (Step C6). Furthermore, the discrimination memory 1 of the seat ECU 16
The height, tilt, and reclining of the seat 21 are reproduced based on the position data stored in the area designated by the position number stored in 6a (step C
7). Then, the sliding position of the seat 21 is added to the sliding position stored in the memory 16e by, for example, 50 mm, and the sliding position of the seat 21 is adjusted so as to be at that position (step C8). In this way, the seat 21 is slid 50 mm behind the driving position as shown in FIG. 5 (A), so that the driver can easily get in the vehicle.

By the way, when it is determined as “NO” in the above-mentioned step C2, that is, when a driver different from the previous one gets on, for example, when the A driver gets on last time and the B driver gets on this time, each driving equipment Since the position needs to be adjusted again, the process proceeds to the processing after step C4, and the position of each operating equipment is reproduced.

In addition, when it is determined as “NO” in the above step C3, that is, the same driver as the previous time gets on so that the A driver gets on the previous time and the A driver gets on this time, and moreover, the position of the driving equipment is set last time. If the position adjusting motor has not been driven after the reproduction, it is not necessary to reproduce the position of the driving equipment again, so the above steps C4 to C8
Is skipped. For example, when the motor m6 that controls the slide position of the seat 21 is driven to control the height position based on the position data stored in the memory 16e, since the seat 21 has inertia, the seat EC
Even after U16 outputs a stop signal to the motor m6, the seat 21 slightly moves. In other words, there is a problem that hunting occurs before the position control ends due to overshoot. However, as described above, the same driver as the previous one gets on the vehicle and the position of the driving equipment is reproduced last time. If the adjustment motor is not driven, there is no need to reproduce again, so hunting during reproduction is prevented by skipping the reproduction process in steps C4 to C8.

<Drive position reproduction operation (step B5)> When the switch IGSW1 detects that the ignition key has been inserted into the key cylinder, the host ECU 15 causes the seat ECU 16 and the tilt ECU 17 to reproduce the driving position via the serial data line D1. Command. As a result, the control shown in FIG. 16 is performed, and the position of the seat 21 is set by the seat ECU 16 as shown in FIG.
It is slid 50 mm forward from the entry / exit position set in step 8 (step D1). Further, by the control of the tilt ECU 17, the steering 22 is tilted based on the tilt data stored in the area designated by the position number in the memory 17e (step D2).

<Standard setting operation (Step B7) What is this standard setting operation?
This function automatically adjusts the position of other driving equipment (such as a rearview mirror) to an appropriate position by operating 1 to set the sliding position of the seat 21. The operation will be described below with reference to the flowchart in FIG. After the driver operates the slide switch 161 to adjust the slide position of the seat 21 (step E1), the “STANDAR
When you operate the "D" (standard setting) key 19b, the host ECU15
Judges its operation (step E2), judges whether the shift position detected by the inhibitor switch 154 is "P (parking)" (step E2a), and if the shift position is "P", the vehicle speed sensor 150 It is determined whether the detected vehicle speed V is equal to or lower than a predetermined vehicle speed (for example, 3 km / h) (step E2b). That is, in this determination, it is determined whether the vehicle is stopped. If it is determined in this step E2b that the vehicle is stopped, the fact that the standard setting has been designated to another ECU is multiplexed and transmitted via the serial data line D1. The seat ECU 16 receiving this command stores the memory 16b
From the slide position of the seat 21 and the physique of the driver (standard sitting height, arm length, etc.) based on a map (not shown)
And the position of the shoulder of the driver (x
2, y2) is determined (step E3). Next, referring to the map of FIG. 32, the front height amount with respect to the slide position,
The rear height amount and the reclining angle are determined, and the front height, the rear height and the reclining of the seat are adjusted based on each amount (step E4). Next, the tilt amount of the steering wheel 22 is set based on the shoulder position (x2, y2) and the reclining angle of the seat 21 determined in step E4. Based on this tilt amount, tilt ECU1
7 controls the tilt of the steering 22 (step E
Five). Next, based on the standard sitting height of the driver's physique estimated in step E3 and the seat reclining amount and seat rear height amount determined in step E4, a map (not shown) is referred to and the driver's eye position y3 ( 31
Figure) is determined. Further, an eye position x3 is determined with reference to a map (not shown) based on the seat slide position, the standard sitting height, and the seat reclining amount (step E).
6). Thus, the eye position (x3, y3) is determined. Next, the horizontal angle Θh of the room mirror 20 is set to z1.
(Fixed value) and x3 to determine from a map (not shown), and determine the vertical angle Θv based on y3, y4, x3 with reference to a map (not shown). Then, the position of the room mirror 20 is controlled by the host ECU 15 so that the determined horizontal direction angle Δh and vertical direction angle Δv are obtained (step E7). The horizontal angles Dx and Dx 'and the vertical angles Dy and Dy' of the outside mirrors 14 and 23 are determined by the above-described steps.
It is determined from a map (not shown) based on the eye position (x3, y3) determined in E6. Then, the positions of the outside mirrors 14 and 23 are controlled under the control of the door ECUs 13 and 18 (step E8).

In this way, if the seat slide amount is determined,
Since the positions of all other driving equipment are adjusted automatically, 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 individually adjusted by operating the manual switch by the driver.

First, the manual operation of the outside mirror 14 will be described. When the driver operates the manual switch 131, the door ECU 13 determines the operation direction (left or right) of the manual switch 131, and performs control to rotate the motor m2 forward or reverse while the manual switch 131 is operated. As a result, the outside mirror 14 is controlled to rotate left and right. Then, the horizontal angle of the outside mirror 14 is converted into a voltage signal according to the horizontal angle detected by the hall element 135, and is sent to the door ECU 13. The door ECU 13 converts the voltage signal into a digital amount and stores it as a horizontal angle Dx in the memory 13b.

Similarly, when the driver operates the manual switch 132, the operation direction (up and down) is determined by the door ECU 13, and the motor m is operated while the manual switch 132 is operated.
1 is controlled to rotate forward or reverse, and the outside mirror 14
Is rotated upward or downward. Then, the vertical angle of the outside mirror is detected by the Hall element 134 and converted into a voltage signal corresponding to the vertical angle, and the door ECU 1
Sent to 3. The door ECU 13 converts the voltage signal into a digital value and stores it as a vertical angle Dy in the memory 13b. In this way, the manual switch 131 or 1
When the position of the outside mirror 14 is adjusted by operating 32, the position data (vertical direction angle Dy and horizontal direction angle Dx) is stored in the memory 13b.

Next, the manual operation of the room mirror 20 will be described. When the driver operates the manual switch 151, the host ECU 15 determines the operation direction (left or right) of the manual switch 151, and performs control to rotate the motor m5 forward or reverse while the manual switch 151 is operated. As a result, the room mirror 20 is controlled to rotate right and left. Then, the horizontal angle of the room mirror 14 is detected by the Hall element 154, converted into a voltage signal corresponding 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 as a horizontal angle Δh in the memory 15b.

Similarly, when the driver operates the manual switch 152, the operation direction (up / down) is determined by the host ECU 15, and while the manual switch 152 is operated, the motor m4 is controlled to rotate forward or reverse, and the rearview mirror 20 is moved upward or downward. It is turned downward. Then, the vertical angle of the room mirror is detected by the Hall element 153, converted into a voltage signal corresponding to the vertical angle, and sent to the host ECU 15. The host ECU 15 converts the voltage signal into a digital amount and stores it in the memory 15b as a vertical angle Δh. In this way, the manual switch 151 or 1
When the position of the rearview mirror 20 is adjusted by operating 52,
The position data (vertical angle {v and horizontal angle}
h) is stored in the memory 15b.

Next, the manual operation of the seat 21 will be described.
As described above, the posture of the seat 21 is controlled by the four motors.

First, when the slide switch 161 of the seat 21 is operated, the operation direction (front, rear) is determined by the seat ECU 16, and the motor m is operated while the slide switch 161 is operated.
6 is normally or reversely controlled, and the seat 21 is slid in the front-rear direction. When the motor m6 is rotated, a number of pulses corresponding to the rotation angle are output from the rotation sensor 165 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 the signal of the limit switch LSW1 opened when the seat 21 is at the frontmost position. That is, the count value of the slide counter C1 means a value corresponding to the slide position of the sheet 21. In this way, the motor
When m6 is rotated, a pulse is input 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 reset to the seat ECU.
Detected by CU16, a stop signal is output to motor m6. In response to this stop signal, the processing shown in FIG. 27 is performed. First, the counting operation of the 100 msec timer is started (step F1). Next, the pulse output from the rotation sensor 165 is read into the seat ECU 16, and the slide counter C1 is read.
Is updated (step F2). Then, it is determined whether 100 msec has been counted by the 100 msec timer (step F
3) If the count has not yet been made, pulse reading is continued. When 100 msec is counted by the 100 msec timer, reading of the pulse from the rotation sensor 165 is prohibited (step F4). Then, in consideration of the count value counted by the slide counter C1 and the rotation direction of the motor m6 before the stop, the slide position corresponding to the count value is added to the slide position (absolute value) stored in the memory 16b. Or it is subtracted. That is, the rotation of the motor m6 before the stop is added if the direction of moving the seat 21 backward, and is subtracted if the direction of moving the seat 21 is moving forward.

Since the seat 21 is moved by the inertial force after the stop signal is output to the motor m6, the slide counter C1 is updated by a pulse output from the rotation sensor 165 until 100 msec elapses after the stop signal is output. I have to. This is because the pulse output from the rotation sensor 165 is output as soon as the stop signal is output to the motor m6.
When the input to the slide counter C1 is prohibited, the stop signal is output to the slide counter C1, and a pulse corresponding to the amount of movement of the sheet 21 due to inertia is not input. This is because there is a problem that the amount does not correspond to the amount.

The processing of the seat ECU 16 with respect to the operation of the switches 162 to 164 operated when adjusting the front height, the rear height, and the reclining of the seat 21 is performed by the slide switch 1 described above.
This is the same as the processing for the operation of 61, and the rotation sensors 166-1
From 68 the pulses are counted by the counters C2-C4. Then, the respective movement amounts of the front height, the rear height, and the reclining angle are calculated from the count values of the counters C2 to C4, and the sliding position (absolute value) of the seat 21 is calculated as described above.
The front height Hf, the rear height Hr, and the reclining angle Θ are stored as absolute values in the memory 16b on which the same calculation as in the case of calculating is performed.

Next, an operation of manually adjusting the tilt angle TΘ of the steering 22 will be described. First, switch 17
When 1 is operated, the operation direction (front, back) is tilt ECU17.
The motor m10 is controlled to rotate normally or reversely while the switch 161 is operated, and TΘ is increased or decreased depending on the tilt angle of the steering wheel 22. Then, the tilt angle detected by the potentiometer 172 is measured by the tilt ECU 17.
After A / D conversion, it is stored in the memory 17b.

<Memory Storage Operation (Step B9)> This memory storage operation refers to an operation of storing the position of the driving equipment. That is, after operating the "MEMORY" key 19a of the operation unit 19, the memory number is changed to the "1" key to the "3" key.
By operating and specifying 191 to 193, the current position data of the operating equipment is stored in the area specified by the memory number in the memory of each ECU. Memory number is from "1"
Since there are up to “3”, each ECU can store three types of position data. The operation will be described in detail below with reference to the flowcharts of FIGS. 18 to 20.

First, after operating the “MEMORY” key of the operation unit 19 and keying in the memory number, the series of operations is performed by the host ECU 1.
Detected by 5. As a result, the host ECU 15 multiplexes frame data having a memory storage command and a memory number as control data to another ECU via the serial data line D1. The ECU that has received the frame data determines that a memory storage operation has been performed (step G1), and determines a memory number from the control data (step G2). First, the host ECU 15 stores the room mirror data stored in the memory 15b in an area of the memory 15e specified by the memory number (Step G3).

Hereinafter, the operation of storing the room mirror position will be described with reference to the flowchart of FIG. First, it is determined whether the last played position number matches the memory number to be stored this time (step H1). This step H1
If it is determined as "matched", it is determined whether the position adjusting motor has moved after the last memory reproduction (step H2). If it is determined that “moved” in the determination in step H2, the position data (horizontal angle 方向) of the room mirror 20 stored in the memory 15b is stored.
h, vertical angle Θv) is stored in steps H3 to H5.
Done in. First, it is determined whether or not the position data is within a storage range (memory limit range) that may be stored in the memory 15c (step H3). "YES" in this step H3 determination
If it is determined, 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, if it is determined "NO" in step H3, the 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 so that the position data larger than the memory limit position is not stored.

If the vicinity of the manual adjustment limit position is stored in the memory 15c, the link of the room mirror 20 may be disconnected at the time of reproduction, and the reproduction may not be performed. However, when the position data exceeds the memory limit range, the memory limit position is stored, so that the data can be reliably reproduced.

If “NO” is determined in step H1, the process proceeds to step H3, and if “NO” is determined in step H2, the storage operation performed in steps H4 and H5 is skipped. In other words, the previously played position number is the same as the storage number to be stored this time, and the room mirror is
When it is determined that 20 is not manually moved, it is not necessary to store the same position data again, so the storage operation is skipped. For this reason, the state where the position data used in the previous reproduction is stored in the area specified by the memory number of the memory 15c is maintained. By doing so, even in a state where the playback has been stopped previously due to overrunning from the position where it was attempted to stop due to the inertia force of the room mirror 20, the overrunning position data is read from the memory 15b. Since the data is not stored in the area specified by the memory number of the memory 15s, 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 an area of the memory 13c specified by the memory number (Step G4). When the outside mirror data is stored, the same processing as the processing shown in the flowchart of FIG. 19 is performed. This prevents the link between the male screw 31 and the actuator 33 from being disconnected at the time of reproduction, and prevents reproduction from being impossible.

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

Further, the storage of the seat position performed by the seat ECU 16 is performed (step G6).
This will be described below with reference to the flowchart in FIG.

In FIG. 20, it is determined whether the last reproduced position number matches the memory number to be stored this time (step I1). If it is determined in step I1 that "they match", it is determined whether the position adjusting motor has moved after the last memory reproduction (step I2). Next, the angle (memory limit position) β at which the seat 21 can be tilted from the slide amount x stored in the memory 16b
Is calculated (β = f (x) + a) (step I3). According to the above equation, the angle β is set to an angle at which the seat 21 does not come into contact with a 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 if “YES” is determined, the current position α is stored, and if “NO” is determined. The memory limit position β is stored (steps 14 to 16). In addition,
The positional relationship between α and β is shown in Fig. 35.

In this manner, when the position data exceeds the memory limit range, the memory limit position is stored so that the position data larger than the memory limit position is not stored.

In this way, since the memory limit position β of the seat 21 is determined according to the slide position of the seat 21,
According to the slide position 21, the reclining angle な い that does not bother the person sitting in the rear seat can be reliably obtained, and the safety of the device can be sufficiently ensured. Further, since the detection of the memory limit position β is detected by the relative position from the limit switch LSW4, there is no need to provide a switch for detecting a position corresponding to the memory limit position, so that the device can be simplified. it can.

<Memory Regenerating Operation (Step B10)> This memory regenerating operation refers to an operation of regenerating the position of the driving equipment stored by the processing of the above-described step B9, and the detailed operation is shown in FIGS. I will explain. When the memory number is specified by operating the "1" key to "3" key 191 to 193 of the operation unit 19, the operation is detected by the host ECU 15. As a result, host E
The CU 15 multiplexes and transmits frame data having a memory reproduction command and a memory number to be reproduced as control data to another ECU via the serial data line D1. The ECU that receives this frame data determines that there is a memory reproduction operation (step J1), and determines the memory number from the control data (step J2). And the inhibitor switch 15
It is determined whether the shift position detected in step 4 is "P (parking)" (step N1). If the shift position is "P", the vehicle speed V detected by the vehicle speed sensor 150 is equal to a predetermined vehicle speed (for example, 3 km / sec). h) It is determined whether the following is true (step N2). That is, in this determination, it is determined whether the vehicle is stopped. When it is determined in step N2 that the vehicle is stopped, the host ECU 15 detects the room mirror 20 of the room mirror 20 based on the room mirror data stored in the area designated by the memory number of the memory 15c. Play position (step 13). The reproducing operation of the room mirror 20 will be described with reference to the flowchart of FIG.

In FIG. 21, it is determined whether the last played position number and the memory number operated this time match (step K1). If the result of this step K1 is "match", after the last position playback,
It is determined whether the position adjustment motor has moved (step K2). If it is determined in step K2 that the object has moved, the horizontal position data to be reproduced is substituted for the current position of the room mirror stored in the memory 15c (step K3). That is, as shown in FIG. 36, the current position is (x1, y1) and the return position to be reproduced is (x2, y1).
y2) means the operation of obtaining (x2, y1). Then, it is determined whether (x2, y1) is within the operable range (step K4). That is, it is determined whether (x2, y1) is within the circle in FIG. Here, if it is determined that the operation range is within the operable range, first, the motor m5 is driven so that the horizontal angle of the room mirror 20 is equal to the horizontal angle Θh stored in the memory 15c. Is automatically adjusted (step K5). Next, the motor m4 is driven to automatically adjust the vertical angle of the room mirror 20 to be equal to the vertical angle Θv stored in the memory 15c (step K6). On the other hand, if it is determined as `` NO '' in step K4, the order of the automatic adjustment is reversed, the motor m4 is driven, and the vertical angle Θv of the room mirror 20 is equal to the vertical angle of the memory 15c. After the automatic adjustment, the motor m5 is driven to automatically adjust the horizontal angle of the rearview mirror 20 to be equal to the horizontal angle Δh stored in the memory 15c (step K9).

Thus, when reproducing the position of the rearview mirror 20, if the horizontal angle is in a range where the motor m5 cannot operate, the motor m4 is driven to adjust the vertical angle, and then the horizontal angle is adjusted. By doing so, even when the horizontal angle of the reproduction position is out of the circle in FIG. 36, it is possible to reliably return to the reproduction position. Further, by adjusting the other angle after the adjustment of the angle in one direction is completed, hunting during the reproducing operation can be prevented. That is, when the position of the room mirror 20 is reproduced, for example, if the motor m4 is adjusted to adjust the vertical angle, the horizontal angle of the room mirror 20 also slightly changes due to this adjustment. Therefore, when the vertical angle is adjusted after adjusting the horizontal angle of the room mirror 20, the initially adjusted horizontal angle slightly fluctuates, and the memory
Not equal to the data stored in 15c. In this case, if the horizontal adjustment is performed again, the room mirror 20 will hunt. In order to prevent this hunting, the reproduction operation is completed when the angle in one direction is adjusted and then the other angle is adjusted.

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

Next, the tilt ECU 17 reads the tilt data stored in the area of the memory 17c specified by the memory number, and drives the motor m10 so as to be equal to the current tilt data stored in the memory 17b. Thus, the tilt of the steering wheel 22 is reproduced (step J
Five).

Next, the position of the sheet 21 is reproduced, and the detailed operation will be described below with reference to FIG. In FIG. 23, it is determined whether the last reproduced position number matches the memory number operated this time (step L1). If it is determined in step L1 that they match, it is determined whether the position adjustment motor has moved after the last position reproduction (step L2).
If it is determined in step L2 that the seat 16 has moved, the slide position of the seat 16, the front tilt, the rear tilt, and the reclining angle are stored in the area of the memory 16c designated by the memory number. Driving of the motors m6 to m9 is started so as to be equal to the sheet data (step L3). Hereinafter, a case where the slide position of the seat 21 is adjusted will be described for simplicity. In step L3, the transistor Q1 shown in FIG. 12 is driven to start the normal rotation drive of the motor m6, and the timer T1 starts counting time (step L3).
Four). The time from when the motor m6 is driven is counted by the timer T1. Then, it is determined whether or not the slide position of the seat 21 has reached the reproduction position (step L5), and if not, the timer T1 is counted up (step L6).

If it is determined in step L5 that the slide position of the sheet 21 has reached the reproduction position,
It is determined whether the time measured at T1 is less than or equal to T2 time (for example, 100 msec) (step L7). If it is determined as `` NO '' in the determination of step L7, and if it is determined that the slide position has been adjusted to the reproduction position by taking the time of T2 or more after driving the motor m6, the transistor Q1 is controlled by the control of the seat ECU 16. Is turned off, and the motor m6 is stopped (step L8).

On the other hand, when it is determined as “YES” in the above-described step L7, control for turning on the transistor Q2 is performed (step L9). Thus, any transistor Q1
When Q2 and Q2 are turned on, the voltage V is applied to both ends of the motor m6, so that the rotation of the motor m6 is stopped. And
After the time T2 has elapsed by the T2 timer, the transistor Q1
And Q2 are turned off (steps L10 and L11).

With this configuration, the transistor Q1 is turned on to finely adjust the seat position, and the relay coil 51 is turned on.
100mse after driving the motor m6
When the playback position is reached within c, the transistor Q1 is not turned off, but the transistor Q2 is turned on to stop the motor m6, so the current in the relay coil 51 is cut off within 100 msec. It is possible to prevent the 51 from being destroyed.

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

<Mirror correction interlocking operation (step B11)> This mirror correction interlocking operation means that the standard setting operation in step B6, the manual operation in step B8, the memory storing operation in step B9, and the memory reproducing operation in step B10 are all completed. When the reclining of the seat 21 is tilted in this state, the position of the rearview mirror 20 and the outside mirrors 14 and 23 are interlocked and corrected according to the variation amount Δθ of the reclining angle Θ. Hereinafter, the mirror correction interlock will be described with reference to the flowchart of FIG. In FIG. 24, the “canc”
The host ECU 15 determines whether the indicator that is turned on when the "el" key 19c is operated is turned off. This "cancel" key 19c is operated by the driver when canceling the mirror correction interlocking operation,
When the "cancel" key 19c is operated, the indicator is turned on. If "YES" is determined in this step M1, the mirror correction interlock is not canceled, so the determination in steps M2 to M4 is performed. If it is determined in steps M2 to M4 that the data is after the standard setting operation, the memory reproduction operation, or the memory storage operation, the process proceeds to step M5 and subsequent steps.

As described in the configuration, the seat ECU 16 sends the seat data and the reclining change amount ΔΘ to the host ECU 15 via the seat data line D2 by communication. The host ECU 16 determines whether the amount Δ 量 is equal to or greater than “0”, and determines whether the reclining of the seat 21 has changed (step M5). If it is determined in step M5 that the reclining has changed, the change amount Δ
It is determined whether Θ is equal to or more than Δα and equal to or less than Δβ (step M6). Here, the reason why the change amount ΔΘ is set to the lower limit value Δα is that it is considered that movement of the mirror with respect to a minute reclining fluctuation of the seat 21 is unnecessary and movement. If the determination in step M6 is "YES", the position of the seat 21 before the reclining change Θ ₁
And the changed position Θ ₂ are determined to have a relation of “α ≦ Θ ₁ , β ≦ Θ ₂ ”. If the determination in step M7 is "YES", the host ECU 15 corrects the position of the room mirror 20 by α ₁ (step M8). Further, the host ECU 15 outputs a mirror correction interlocking start command to the door ECU 13, and an operation of correcting the outside mirror 14 by β ₁ is performed (step M9). As described above, the angles of the room mirror and the outside mirror are corrected in accordance with the amount of change in the reclining of the seat 21.

By the way, in the processing of the above steps M2 to M4,
When it is determined to be "O", the processing after step M5 is skipped, and the mirror correction interlocking operation is not performed. Further, if the determination in steps M5 to M7 is “NO”, the determination in steps M8 and M9 is skipped,
No mirror correction interlocking operation is performed.

<Easy access operation (step B15)> In this easy access operation, when the key cylinder of the ignition key is pulled out, the seat 21 is retracted from the driving position by 50 mm and the steering 22 is flipped up to the uppermost position, so that the driver gets off the vehicle. An operation that facilitates easy operation. When the host ECU 15 detects that the ignition key has been removed from the key cylinder by the signal from the switch IGSW, 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 the shift position is "P".
If so, 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 N
2). That is, in this determination, it is determined whether the vehicle is stopped. If it is determined in step N2 that the vehicle is stopped, the host ECU 15 multiplexes and transmits a data frame having information for performing an easy access operation to the seat ECU 16 via the serial data line D1. . The seat ECU 16 that receives this data frame proceeds to step B
The slide position (driving position) when the ignition switch is turned off is read from the position data stored in the temporary memory 16d in step 15 and the rotation of the motor m6 is controlled so that the slide position is retracted by 50 mm. (Step N3). Then, the host detects that the driver's door has been opened by a signal from the door switch DRSW.
When detected by the ECU 15, the host ECU 15 becomes the tilt ECU 17
A multiplexed data frame having information for performing an easy access operation is transmitted via the serial data line D1. The tilt ECU 22, which has received the frame data, drives the motor m10 to tilt the steering wheel 22 up to the uppermost position (step N5). By the way, the above steps N1, N
If it is determined to be "NO" in 2 and N4, the easy access operation is not performed.

As described above, when it is detected that the driver gets off the vehicle, the position of the seat 21 and the steering 22 are automatically moved to a position where the driver can easily get off the vehicle. twenty two
It is possible to save the trouble of manually moving the vehicle to a position where it is easy to get off.

<Drive position storage operation (step B17)> This drive position storage operation is a memory in which, when the door is detected to be locked, the driving position of the driving equipment saved in the temporary memory of each ECU is designated by the position number. Means to store the information. The seat and the steering position are moved to a position where it is easy to get off by the easy access operation of step B15, the driver gets off, and the light emitting element 11e that operates the transmission switch 11b of the key toward the receiver 31 of the door operates the light emitting element 11e Infrared signal is transmitted. The infrared signal is received by the light receiving element 31a, converted into a digital signal, and output to the keyless ECU 12 as a keyless code. And this keyless ECU
At 12, it is judged whether the keyless code input as shown in FIG. 13 is the keyless code of the A driver or the keyless code of the B driver (steps A1 and A2). When it is determined that the input keyless code is the keyless code of the A driver or the B driver, a coincidence signal is output to the door ECU 13. This match signal also includes an identification signal indicating which of the driver A and the driver B has matched the keyless code.

When the coincidence signal is output to the door ECU 13, the door ECU 13
Detects the state of the lock switch 133, and since the door is in the unlocked state, the motor m3 is driven to lock the driver side door. Then, the host ECU 15 serializes a data frame including an identifier indicating whether the driver side door is locked by keyless entry and an identifier indicating which driver is locked (hereinafter, referred to as a position number). The data is multiplexed and transmitted to each of the ECUs 15 to 18 via the data line D1. Each ECU that has received the data frame first determines whether the door has been locked by a keyless entry operation (step P1). If the result of this determination is “YES”, the position number is determined from the received data frame (step P2). And the above steps
At B13, 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 designated 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 temporary memory 16d is stored in an area of the memory 16e designated by the position number. Then, the position number stored in the discrimination memory of each ECU is cleared (step P4).

On the other hand, if it is determined to be "NO" in step P1, the processing from step P5 is performed. First, insert the ignition key into the key hole of the door to lock the door, or if the door is locked by operating the door lock knob without using the ignition key, proceed to step C1 in FIG. 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, seat ECU21
If so, the driving position of the sheet 21 stored in the temporary memory 16d is stored together with the position number in the area of the memory 16e designated by the position number. Then, the process proceeds to step P4 to clear the position number stored in the determination memory.

In this way, the driving position of each driving equipment is automatically stored when the door is locked as well as the keyless. In this way, when the vehicle gets off and the door is locked, the driving position is automatically stored, so that the driver does not have to perform the operation of storing the driving position indoors before getting off the vehicle.
As a result, the storage operation 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, the sheet data stored in the memory 16e, which is a volatile memory, is a non-volatile memory. It is a function to save in the save memory 16h. As shown in FIG. 28, seat ECU 16 detects battery voltage Vt at every predetermined sampling time (step Q
1) The battery voltage change rate ΔVt is calculated from the voltage Vt ′ detected at the previous sampling (step Q2).
Then, it is determined whether the sign of the rate of change ΔVt is negative (step Q3). If “YES” is determined in this step Q3, it is determined that the battery voltage Vt is on a decreasing trend. Then, proceeding to the determination of step Q4, 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, "YES"
Is determined, it is determined whether the absolute value of ΔVt is equal to or greater than ΔV1 (step Q5). Since the determination in step Q5 is that the rate of change ΔVt of the battery voltage that occurs when the battery is removed is large, the rate of change ΔVt is equal to the predetermined rate of
It is determined whether or not it is the above, and it is determined that it is a precursor of battery removal. Then, in this step Q5, when it is determined to be "YES", it is determined that the battery is removed, and the transfer operation for transferring the sheet data stored in the memory 16e to the save memory 16h is automatically performed on the sheet E.
This is performed under the control of CU16 (step Q6).

On the other hand, when it is determined to be "NO" in step Q3, it is determined that the battery voltage Vt is increasing. Then, proceed to the determination in step Q7, and the battery voltage
It is determined that Vt is equal to or higher than the predetermined voltage V2. And
If "YES" is determined in this step Q7, it is determined whether the absolute value of ΔVt is ΔV2 or more (step Q8). Since the rate of change ΔVt of the battery voltage that occurs when the battery is attached is large in the determination in step Q8,
It is determined whether the rate of change ΔVt is greater than or equal to a predetermined rate of change ΔV2, and it is detected that this is a sign of battery mounting.
Then, in step Q8, when it is determined to be "YES", it is determined that the battery is attached, and the sheet data (absolute position) stored in the save memory 16h is stored in the memory 16e.
The transfer operation to transfer the data is automatically performed under the control of the seat ECU 16 (step Q9).

In this way, if the battery is removed, the memory
Since the seed data stored in 16e is saved in the non-volatile memory and the sheet data is automatically restored to the memory 16e when the battery is attached, even if the battery is removed. The seat absolute position stored in the memory 16e can be continuously stored. As described above, the position of the seat 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, move the seat once to open the limit switch, and then move to the drive position to determine the seat absolute position. It can be stored in the memory 16e. However, by automatically retracting the seat absolute position stored in the memory 16e even if the battery is removed as described above, there is an effect that the above-mentioned operation need not be performed.

<Diagnosis code output function> Each ECU has a self-diagnosis function, and a diagnosis number corresponding to a failure detected in each ECU by the self-diagnosis function is stored in a diagnosis code storage unit of each ECU. When a diagnostic code detection tester is connected to a diagnostic connector (not shown), the line b
Is grounded. When this line b is grounded, the host EC
U15 sends a command to output a diagnosis code to the ECUs 13, 16 to 18 in a data frame format. Upon receiving this data frame, the door ECUs 13 and 18 put the diagnosis code in the data frame and output it to the host ECU 15. The sheet ECU 16 outputs a diagnosis code to the host ECU 15 via the sheet data line D2. Further, the tilt ECU 17 outputs a diagnosis code to a diagnosis connector via a line c. In addition, door ECU13,18
The host ECU 15 that has received the diagnosis code output from the seat ECU 16 outputs the diagnosis code together with the diagnosis code stored in its own diagnosis code storage unit 15f to the diagnosis connector via the line a.

In this way, the diagnosis codes detected by the door ECUs 13, 18 and the seat ECU 16 can be converted to the diagnosis codes without providing a diagnosis code output line to be connected to a predetermined pin of the diagnosis connector from each of the door ECUs 13, 18 and the seat ECU 16. Can be output to a diagnostics detection tester via.

Further, in the above embodiment, the counters C1 to C4 are configured to be reset when the switches 161 to 164 are set to the neutral position, but are reset when the front end positions are detected by the limit switches LSW1 to LSW4. Then, the count values corresponding to the absolute positions of the counters C1 to C4 may be counted.

Further, in the above embodiment, the switch IGSW1 is connected to the host ECU 15, but the switch IGSW1 may 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 detect the insertion state of the ignition key independently from the data frame transmitted from the host ECU 15 without detecting the insertion state of the ignition key. Therefore, in the driving operation of the driving position (step B5), the seat ECU 16 and the tilt ECU 17 independently detect the insertion of the ignition key and perform the driving position reproduction regardless of the command from the host ECU 15. good.

In the above embodiment, the switch ECU is connected to the host ECU 15.
The GSW1 and the door switch DRSW are connected, but the switch IGSW1 contact DRSW is connected to the seat ECU 16 and the tilt ECU 17
May also be connected. In this case, the seat ECU 16 and the tilt ECU 17 independently detect the open / closed state and the inserted state of the door based on the data frame transmitted from the host ECU 15 without detecting the opened / closed state of the door and the inserted state of the ignition key. be able to. Therefore, in the easy access operation (step B15),
The seat ECU 16 and the tilt ECU 17 can also start the easy access operation without receiving a command from the host ECU 15.
