Abstract
Disclosed is a rear wheel neutralizing system for a four-wheel steering vehicle, including an actuator for returning rear wheels to their neutral positions; a potentiometer for detecting a returning displacement to the neutral position of the wheel; a motor for operating the actuator; a vehicle speed sensor for detecting vehicle speeds; and an electronic control unit for determining whether the four-wheel steering system is malfunctioning and for operating the motor while receiving a signal from the vehicle speed sensor. The rear wheel neutralizing system further comprises an encoder for detecting the angular velocity of the motor and transmitting a signal on the angular velocity to the electronic control unit.
