Claims

[Scope of utility model registration request]

a steering wheel rotation sensor that detects the rotation of the steering wheel of an automobile; a front wheel steering angle calculation means that calculates the steering angle of the front wheels based on a steering wheel rotation signal output from the steering wheel rotation sensor; and a hand rotation output from the steering wheel rotation sensor. A left-turn/left-turn determination means detects whether the steering wheel is turned to the right or left based on a traffic signal, and the front wheel steering angle calculated by the front wheel steering angle calculating means determines whether the steering angle of the front wheels is equal to or greater than the operating angle. an operation comparison means for detecting, a return comparison means for detecting whether the front wheel steering angle calculated by the front wheel steering angle calculation means is equal to or less than a return angle, and an operation for driving a solenoid that steers the rear wheels at a fixed angle. a return solenoid drive circuit that drives a solenoid that returns the steering of the rear wheels to the neutral position; and a return solenoid drive circuit that drives a solenoid that returns the steering of the rear wheels to the neutral position, and the operation solenoid drive circuit that operates when the steering angle of the front wheels is equal to or greater than the operating angle according to the operation comparison means. to steer the rear wheels at a certain angle in the opposite direction to the front wheels based on the left turn/left turn determination means, and when the steering angle of the front wheels becomes equal to or less than the return angle according to the return comparison means, the return solenoid is activated. A rear steering control device comprising means for driving a drive circuit to restore rear wheel steering.
