Abstract
An electronic control unit receives a detection value from each sensor, and determines a familiarity degree coefficient indicating the degree of driver's familiarity with steering characteristics, using the received detection values. When the coefficient has a value near '0', a desired actual steering angle is calculated to be a small value, and when the coefficient has a value near '1', a desired actual steering angle is calculated to be a large value. When the coefficient has a value near “0”, a time constant of an actual steering actuator is set to a large value, and when the coefficient has a value near “1”, the time constant is set to a small value. A reaction torque is determined based on the coefficient.
