PEDAL EFFORT REDUCTION DEVICE OF VEHICLE AND CONTROL METHOD THEREOF FOR IMPROVING DRIVER'S CONVENIENCE IN OPERATION THROUGH PROPER REDUCTION OF PEDAL EFFORT

摘要

PURPOSE: A pedal effort reduction device of a vehicle and a control method thereof are provided to make a driver conveniently operate pedals by properly reducing pedal effort of pedals while securing reliability in operation and stability of pedals. CONSTITUTION: A pedal effort reduction device of a vehicle comprises an electric motor(7) having a rotating pulley(5) to wind on a cable(3) of a pedal(1) and apply tensile force to the cable of the pedal; a pedal effort sensor(9) installed to the pedal to measure driver's pressing force; and a controller(11) receiving a signal of the pedal effort sensor and driving the electric motor. The pedal effort sensor is a strain gauge attached to the surface of the pedal.
