RACKSTROCK CONTROL METHOD FOR SENSITIVITY OF DRIVER

摘要

PURPOSE: A lac stroke control method considering sensitivity of a driver is provided to minimize a strange feeling the driver feels even when restoring of a steering wheel center is performed by a lac stroke reduction control by providing the driver to feel that a steering wheel is naturally restores according to movement of a vehicle. CONSTITUTION: A lac stroke control method considering sensitivity of a driver comprises the following steps. (First determining stage) An electronic control device(100) determines whether a transmission control for driving a vehicle is set as a moving backward transmission. If the result of the determination is set as the moving backward transmission, a driver control steering angle controlled by the driver's used of the steering wheel is determined whether it exceeds a predetermined stop steering angle. (Second determining stage) When the driver control steering angle exceeds the stop steering angle in the result of the determination, generation of a vehicle speed is additionally determined. (Performing stage) When the vehicle speed is generated, a control of reducing a lac stroke of a lac assembly to a predetermined level or lower is performed.
