    摘要: An electric power steering apparatus is provided that has a controller by which no current flows in one phase among current paths of three phases for supplying electric power from a motor driving circuit to a three-phase brushless motor and currents that have an identical absolute value and that have different signs flow in the other two phases. Thus, the status at one energization angle on the driving current waveform of the three-phase brushless motor can be given continuously and relatively-high currents can simultaneously flow in opposite directions in the contacts inserted to the two phases. By flowing of such high current in the contacts, a secure conduction check can be performed and foreign matters on the surface of the contact can be fused or thermally destroyed.

    摘要: An electric power steering control includes a torque sensor for detecting steering torque as torque information, a motor for generating assist torque, a calculation section for calculating a motor current command value based on the torque information at each predetermined sampling period, and a motor current control section for driving and controlling the motor based on the motor current command value. The calculation section includes a first target current calculation section for calculating a first target current based on the torque information detected in a time series manner at a first control period corresponding to the sampling period, and a second target current calculation section for calculating a second target current based on the first target current at a second control period shorter than the first control period. The motor current control section controls the motor by using the second target current as the motor current command value.
