Abstract
Abstract A steering wheel positioner for an automatic driving position system is provided with an actuator for driving a steering wheel shaft, a tilt sensor for detecting an inclination of the steering wheel shaft, a car speed sensor, a neutral-park relay for detecting the vehicle to be stepped and a controller for memorizing a steering wheel position suitable for the driver, for driving a steering wheel to the memorized steering wheel position through the actuator, for driving the steering wheel downwardly when the tilt sensor is abnormal, and for preventing the steering wheel from driving in the downward direction when the tilt sensor is abnormal and the neutral-park delay detects the vehicle to be traveling.
