<P>PROBLEM TO BE SOLVED: To provide an electromotive power steering control device in which a noise level is lowered by transferring a motor control sound to a high frequency side while restricting a CPU load. <P>SOLUTION: The electromotive power steering control device is provided a torque sensor 3 for detecting steering torque as torque information TRQ, a motor for generating auxiliary torque, a calculating means for calculating a motor current command value at each predetermined sampling cycle in response to the torque information TRQ and a motor current control means 105 for driving and controlling the motor in response to the motor current command value. The calculating means comprises a first target current calculating means 103 for calculating a first target current io1 at the first control cycle corresponding to the sampling cycle in response to the torque information TRQ detected in time series and a second target current calculating means 104 for calculating a second target current io2 at a shorter control cycle than the first control cycle in response to the first target current io1. The motor current control means 105 controls the motor by using the second target current io2 as the motor current command value. <P>COPYRIGHT: (C)2007,JPO&INPIT |
