CONTROL METHODS FOR REAR WHEEL STEERING APPARATUS OF CARS

A control method for a rear wheel steering apparatus of a vehicle adjusts current applied to a rear wheel steering (RWS) actuator by determining a compensation current value based on the aging of devices installed in the RWS actuator installed in the rear wheel steering apparatus, and further adjusts the current applied to the RWS actuator with a compensation current value based on the friction of the devices installed in the RWS actuator.
