In a more clever embodiment, it is characterized by a control mechanism that prohibits the storage update of operational data within an inactive area, and in a more preferred embodiment, in an inactive area, The present invention is characterized in that it includes a control mechanism that prohibits automatic operation based on a memorized position within an inactive area, and is a means for solving the conventional problems with the configuration of the above-mentioned automatic driving position device. (Function of the Invention) The automatic driving position device according to the present invention has a control mechanism that sets a predetermined range of non-operation areas in memory positions, and in a more preferred embodiment, the control mechanism sets automatic driving position within the non-operation area. In a more preferred embodiment, the control mechanism inhibits the storage update of operating data in the inactive area, and in a more preferred embodiment, the control mechanism inhibits storage update in the inactive area in the inactive area. Based on the position (Auto operation is prohibited, so even if the motor coasts from the memorized position, the control mechanism will not carry out the prescribed processing in the inactive area, so there will be no movement between the memorized position and the motor stop position.) The deviation will be small. (Embodiment) An automatic driving position device according to an embodiment of the present invention will be described below with reference to FIGS. 1 to 6. That is, in the illustrated automatic driving position device 1, a tilt motor 3 that changes the tilt angle of a steering wheel 2 between an uppermost position A and a lowermost position B is connected to a control mechanism 4. 3 is equipped with a tilt sensor 3a that counts the amount of operation of the tilt motor 3 and outputs tilt operation data. Further, a telescopic motor 5 that changes the telescopic position of the steering wheel 2 between the front position C and the rear position is connected to the control mechanism 4. A telescopic sensor 5a is provided for outputting telescopic operation data. A seat motor 7 that slides, lifts, and reclines the seat 6 is connected to the control mechanism 4, and the seat motor 7 includes a seat sensor 7a that counts the amount of operation of the seat motor 7 and outputs seat operation data.
is the preparation. A seat switch 8 is also connected to the control mechanism 4, and a command signal from the seat switch 8 operates a seat motor 7 that slides the seat 6 between the seat position E and the seat F position. The seat switch 8 is connected to the tilt motor 3. A set switch 8a is provided for storing the telescopic motor 5 and the seat motor 7 at arbitrary stop positions. Furthermore, a steering position switch 2 is connected to the control mechanism 4, and is provided with an auto-operation changeover switch 2a, and a command signal from the steering position switcher controls the tilt motor 3 and the telescope. Motor 5 is now activated. Furthermore, the control mechanism 4 has a built-in I10 interface circuit (not shown) and a microcomputer (not shown) connected to the I10 interface circuit. The operation data and the sheet operation data from the sheet sensor 7a are kept together for a long time. Here, when setting a driving position suitable for the driver, by operating the steering position switcher, the tilt motor 3 is operated to the tilt position G suitable for the driver, and the telescopic position H suitable for the driver is operated. By operating the telescopic motor 5 and operating the seat switch 8, the seat motor 7 is operated to a seat position I suitable for the driver. Then, in this state, by performing a set operation (memory operation) on the set switch 8a provided in the seat switch 8, the microcomputer via the I10 interface circuit changes the position of the steering wheel 2 from the current position to the memorized position by the set operation. Stores tilt operation data, telescopic operation data, and seat operation data. Thereby, by operating the set switch 8a, the tilt position G, telescopic position H, sea 1 . Tilt motor 3. Telescopic motor 5. The seat motor 7 is operated in memory to reproduce a driving position suitable for the driver. Also, with the auto operation selector switch 2a provided in the steering position switch 2 set to the auto operation side, remove the ignition key (not shown), or open the door with the ignition key inserted, or open the door. When the ignition key is turned from the ACC position to the OFF position with the ignition key opened, the control mechanism 4 causes the tilt motor 3. Telescopic motor 5. A retraction operation signal is sent to the seat motor 7. In response to this evacuation operation signal, the tilt motor 3 is actuated to move the steering wheel 2 from the tilt position G (memory position) to the uppermost position A (evacuation position) and then stopped, and the telescopic motor 5 is actuated to move the steering wheel 2 through the telescopic position. It is moved from position H (memory position) to front position C (retracted position) and then stopped, and the seat motor 7 is activated to move the seat 6 to a rear slide position where it is moved a predetermined amount rearward from the seat position (memory position). It is moved to F (retracted position) and stopped to enter the retracted state. In this state, the ignition key is inserted, or the door is closed while the ignition key is inserted, or the ignition key is switched to the ACC.
When the position is changed to the ON position, the control mechanism 4 causes the tilt motor 3, telesco motor 5. A return activation signal is sent to the seat motor 7. In response to this return operation signal, the tilt motor 3 is activated to move the steering wheel 2 from the highest position A (retracted position) to the pre-retracted tilt position G (current position), and the telescopic motor 5 is activated to move the steering wheel 2 forward. The seat motor 7 is moved from position C (retracted position) to telescopic position H (current position) before retraction, and the seat motor 7 is activated to move the seat 8 from rear slide position F (retracted position) to seat position I (current position) before retraction. The vehicle is returned to the rest state by sliding the vehicle up to the maximum position to reproduce a driving position suitable for the driver. As shown in FIGS. 3, 4, and 5, the control mechanism 4 has a predetermined non-operation area N set at the memory position processing is not performed. That is, in one embodiment shown in FIG. 3, the output for automatic operation is turned off within the non-operating region N. In this case, after the evacuation operation signal is sent, the return operation signal is sent, and the tilt motor 3. Telescopic motor 5. The seat motor 7 is at the current position (retracted position) Z (top position A,
When automatically operating from the front position (C9, rear slide position F) to the memory position (return position) X (tilt position G, telescopic position H, seat position I), the inoperative area N By entering, the automatic operation (signal for return operation) is canceled. This causes the tilt motor 3. Even if the telescopic motor 5 and the seat motor 7 coast, their outputs are turned off just before they reach the storage position X, so they stop at approximately the same position as the storage position. In another embodiment shown in FIG. 4, the memory of the tilt motion data from the tilt sensor 3a, the telescopic motion data from the telescopic sensor 5a, and the seat motion data from the seat sensor 7a are updated within the non-operating area N. It is something that should not be done. In this case, after the evacuation operation signal is sent, the return operation signal is sent, and the tilt motor 3. Telescopic motor 5. The seat motor 7 is in the retracted position Z (top position A, front position C9
from rear slide position F) to return position X (tilt position G,
Telescopic position H. When automatically operating up to the seat position I), by entering the non-operation area N before reaching the return position X, updating of each operation data is prohibited within the non-operation area N. In other words, if auto operation is performed once again after auto operation has been performed - times, the memory is not updated as the return position Even if 3, 5.7 deviates from the return position X associated with the first auto operation and has stopped, when the second auto operation is performed,
- Stops at return position X due to the second auto operation. In another embodiment shown in FIG. 5, automatic operation based on the memory position X within the non-operating area N is not performed within the non-operating area N. In this case, the set switch 8 provided in the seat switch 8
There is a positional deviation due to motor coasting, etc. between the memory position x1 caused by the set operation in step a and the memory position Even if the motor 3.5.7 does not operate based on the memory position x1 of the non-operation area N within the non-operation area N, each motor 3.5. It will stop at position x1. During this time, the control mechanism 4 in the embodiment shown in FIG. 4 performs control based on the flowchart shown in FIG. That is, the program is started when power (not shown) is supplied, and in step 200 it is determined whether or not there is a signal for evacuation operation (evacuation signal), that is, the auto operation changeover switch 2a provided in the steering position switch 2 is set to auto operation. The ignition key is removed while the ignition key is turned to the side, or the ignition key is inserted and the door is opened, or the ignition key is moved from the ACC position to the OFF position with the door open. We are determining whether or not it has happened. When it is determined in step 200 that the evacuation signal is present (YES), the process proceeds to step 201, and when it is determined that the evacuation signal is not present (no) in step 200, the process proceeds to the next step 202 and the return operation is performed. Whether there is a return signal (return signal), that is, whether the ignition key is inserted, whether the door is closed while the ignition key is inserted, and whether the ignition key is changed from the ACC position to the ON position. It is determined whether Then, in step 202, there is a return signal (YES).
), the process moves to step 203,
When it is determined in step 202 that there is no return signal (NO), the process returns to the first step 200. In step 201, which is proceeded to after it is determined that there is an evacuation signal in step 200, it is determined whether or not the return flag is 1. When it is determined that the return flag is 1 (YES), the process proceeds to step 204. However, if it is determined in step 201 that the return flag is not 1 (NO), the process moves to the next step 205. In step 204, it is determined whether the count of the current position - the previous return position is greater than the N count;
In this step 204, the count is greater than N (
When it is determined that the count is YES), the process moves to step 206, and when it is determined that the count is not greater than N (No) at step 204, the process proceeds to step 2.
Move to 05. Then, in step 206, the current position is stored as a new return position, and the process moves to step 205. In step 205, the return flag=0 is input and the process moves to the next step 207. In this step 207, it is determined whether or not it is in the retracted position, and when it is determined in this step 207 that it is in the retracted position (YES), step 208
Then, the output of each motor 3°5.7 is turned off, and the process returns to the first step 200. Also, in step 207, it is not in the retracted position (NO).
When it is determined that this is the case, in step 209, a retraction operation signal is output to operate each motor 3, 5.7 in the retraction direction, and the process returns to the first step 200. On the other hand, in step 203, the return flag=1 is input and the process moves to the next step 210, where it is determined whether or not it is in the return position. When it is determined in step 210 that the motor is in the return position (YES), the output of each motor 3, 5.7 is turned off in step 211, and the process returns to the first step 200. Also, in step 210, it is not in the return position (NO).
When it is determined that this is the case, a return operation signal is output in step 212 to operate each motor 3, 5.7 in the return direction, and the process returns to the first step 200.
