Claims

[Scope of utility model registration request]

A steering wheel rotation sensor that detects rotation of a steering wheel of an automobile, a front wheel steering angle calculation means that calculates a steering angle of a front wheel based on a steering wheel rotation signal output from the steering wheel rotation sensor, and a steering wheel rotation signal output from the steering wheel rotation sensor. right-turn/left-turn determination means for detecting whether the steering wheel is turned to the right or left; and an operation for comparing whether the front wheel steering angle calculated by the front wheel steering angle calculation means is equal to or greater than the operating angle. return comparison means for comparing whether the steering angle of the front wheels calculated by the front wheel steering angle calculation means is equal to or less than the return angle; and an operating solenoid for driving a solenoid for steering the rear wheels at a fixed angle. a drive circuit, a return solenoid drive circuit that drives a solenoid that returns the steering of the rear wheels to a neutral position, and the operation comparison means that drives the operation solenoid drive circuit when the steering angle of the front wheels is equal to or greater than the operating angle. Then cut to the right above,
The rear wheels are steered at a certain angle in the opposite direction to the front wheels based on the 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 drive circuit is driven to steer the rear wheels. means for returning the steering to a neutral position;
A rear steering control device comprising: a liquid crystal display section that displays the steering status of the front wheels and rear wheels; and means for driving the liquid crystal display section using the right turn/left turn determining means and the operating solenoid drive circuit. .
