Detects sudden acceleration and sudden braking occurring in

In addition, the controller 10 drives the passenger detecting unit 40 to detect whether or not there is a passenger in the passenger seat, and when the driving conditions of the seat seat are satisfied, that is, change the position of the passenger seat during rapid acceleration and sudden braking. It is determined whether or not to perform. In other words, if a passenger is in the front passenger seat, the position of the passenger seat and the back seat is changed in the same way as the position of the driver's seat. If the passenger is not in the passenger seat, even if sudden braking and acceleration are judged, The drive of the motor is turned off.

On the other hand, when the driver starts driving and when the driver determines the rapid acceleration and sudden braking by the sudden start or the like in accordance with the detection result of the braking detection unit 30 and the acceleration detection unit 20, The controller 10 outputs a control signal to the motor driver to drive each motor.

First, as illustrated in FIG. 2A, when the driver accelerates due to a sudden start or the like, the driver's body is pushed in a direction opposite to the progress of the car, so that the back seat is moved with the movement of a person.
