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 calculating means that calculates the steering angle of the front wheels based on the steering wheel rotation signal output from the steering wheel rotation sensor; Based on the steering wheel rotation signal...the front wheel steering angle calculated by the right turn/left turn determining means for detecting whether the steering wheel is turned to the right or left and the front wheel steering angle calculation means is equal to or greater than the operating angle. a return comparing means for detecting whether the front wheel steering angle calculated by the front wheel steering angle calculating means is less than or equal to a return angle smaller than the operating angle; An operating solenoid drive circuit that drives a steering solenoid, a return solenoid drive circuit that drives a solenoid that returns the steering of the rear wheels to a neutral position, and when the steering angle of the front wheels is equal to or greater than the operating angle according to the operation comparison means described above. The operating solenoid drive circuit is driven to steer the rear wheels at a certain angle in a direction opposite to the front wheels based on the right-turn/left-turn determination means, and the steering angle of the front wheels becomes equal to or less than the return angle by the return comparison means. a rear steering control device comprising: means for driving the return solenoid drive circuit to return steering of the rear wheels when the return solenoid drive circuit is turned off;
