<P>PROBLEM TO BE SOLVED: To realize an electric motor controlling system having some effects for restricting a minute vibration of a steering wheel and reducing noise around it. <P>SOLUTION: There is provided means for discriminating a steering state in which a wheel steering speed is larger than an optional value and a steering holding state in which the wheel steering speed is smaller than the optional value under application of means for detecting the wheel steering state. When the steering state occurs, it is controlled in such a way that a difference between a torque instruction value for an electric motor and an actual torque is made small. As means for discriminating the steering state of the wheel, a method for detecting the wheel steering speed is applied. Alternatively, an electric motor for generating a steering reaction force of the wheel is arranged on the steering shaft and a rotation sensor arranged at the electric motor is used. <P>COPYRIGHT: (C)2007,JPO&INPIT |
