FRICTION COMPENSATION APPARATUS OF MDPS SYSTEM AND FRICTION COMPENSATION METHOD THEREOF

摘要

The present invention relates to a friction compensation apparatus of an MDPS system and a friction compensation method thereof. According to the friction compensation apparatus of an MDPS system receiving a column torque signal, processing the column torque signal, and outputting friction compensation torque, the friction compensation apparatus comprises: a accumulation speed control unit controlling the speed of accumulating information of a compensation section set in the column torque signal; and a compensation amount control unit for each vehicle speed controlling the accumulation speed control unit to control the accumulation speed to be faster or slower in accordance with the vehicle speed and controlling a compensation gain to be smaller or larger in accordance with the vehicle speed to output the friction compensation torque.;COPYRIGHT KIPO 2016
