PURPOSE: An MPS(Motor Driven Power Steering) control method according to driving habit learning of a driver is provided to improve productivity of a vehicle by allowing the driver to feel a sense of steering fitted into the driver. CONSTITUTION: An acceleration or deceleration inclination of a driver is determined by the time of changing speed. A steering inclination of the driver is determined by a steering angular velocity. A driving habit of the driver is verified by a reentering angle velocity. The acceleration or deceleration inclination of the driver is grasped by an operation angular velocity of a brake pedal and an acceleration pedal. A compensation torque is adjusted in a steering torque of the driver according to a driving mode of the driver. [Reference numerals] (AA) Start; (BB) Determine a driving habit and determine a corresponding driving mode; (CC) End; (S11) V1 < Vehicle speed < V2, S1 < Speed change time < S2 ?; (S12) V3 < Vehicle speed < V4, A1 < Steering angle speed < A2 ?; (S13) Y1 < Yaw angle speed < Y2; (S14) T1 < Auxiliary steering power < T2; (S15) B1 < Brake pedal operating angular speed < B2, X1 < Acceleration pedal operating angular speed < X2 ?; (S20) Add or subtract compensation torque to or from steering torque according to the driving mode |
