ABSTRACT:
In order to check four-wheel steering characteristics of a four-wheeled vehicle provided with a four-wheel steering system in which both the front wheels and the rear wheels are turned in response to operation of the steering wheel according to preset four-wheel steering characteristics, the steering wheel is turned to turn the front wheels and the rear wheels, and the actual turning angle of the front wheels and the actual turning angle of the rear wheels are measured, thereby detecting the actual relation between the turning angles of the front and rear wheels. Whether the actual four-wheel steering characteristics of the vehicle deviates from the preset four-wheel steering characteristics is determined through comparison of the actual relation between the turning angles of the front and rear wheels with the preset four-wheel steering characteristics.
