Claims

[Scope of utility model registration request]

An ignition switch detection means that detects whether the ignition switch is turned off; a steering wheel rotation sensor that detects the rotation of the steering wheel of the vehicle; and a front wheel steering system that calculates the steering angle of the front wheels based on the steering wheel rotation signal output from the steering wheel rotation sensor. An angle calculation means, a right-turn/left-turn determination means for detecting whether the steering wheel is turned to the right or left based on a steering wheel rotation signal outputted from the steering wheel rotation sensor, and a front wheel steering angle calculating means. an operation comparison means 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; and a return comparison means for comparing whether the front wheel steering angle calculated by the front wheel steering angle calculation means is less than or equal to the return angle. , a solenoid drive circuit for operation that drives a solenoid that steers the rear wheels at a certain angle, and a solenoid drive circuit for return that drives a solenoid that returns the steering of the rear wheels to the neutral position. When the angle is equal to or greater than the operating angle, the actuation lever drive circuit is driven to steer the rear wheels by a certain angle in the opposite direction to the front wheels based on the right-hand turn/left-hand turn determination means, and the front wheels are steered by the return comparison means. means for driving the return solenoid drive circuit to return the steering of the rear wheels to the neutral position when the angle becomes less than the return angle; and the ignition switch detection means detecting that the ignition switch is off. a rear steering control device comprising: means for driving the return solenoid drive circuit to return steering of the rear wheels to a neutral position when the vehicle is in use;
