TORQUE STEER COMPENSATION METHOD OF A MOTOR DRIVEN POWER STEERING CAPABLE OF PREVENTING A TORQUE STEER PHENOMENON DISTORTING A STEERING WHEEL WHEN DRIVING A VEHICLE

摘要

PURPOSE: A torque steer compensation method of a motor driven power steering is provided to reduce vehicle maintenance costs by preventing a torque steer phenomenon after aging according to driving.;CONSTITUTION: A torque steer compensation method of a motor driven power steering includes following steps. A step for determining whether a MDPSMotor Driven Power Steering installed in a vehicle normally functions or not(S10); a step for detecting vehicle information through an ECUElectronic Control Unit equipped in the vehicle(S20); a step for determining whether a torque steer happens or not in detected vehicle information in a vehicle information verification step(S30); a step for calculating the compensation quantity of the MDPS through the ECU when the torque steer happens in a torque steer generation determining step(S40); and a step for compensating the calculated compensation quantity through a MDPS compensation quantity calculating step.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (BB) End; (S10) Motor driven power steering normally operated?; (S20) Detecting vehicle information including steering information, driving information, and ESC information; (S30) Torque steer generated?; (S40) Calculating the compensation quantity of the motor driven power steering; (S50) Rotating a steering wheel by the compensation of the compensation quantity;
