Abstract: A SBW-ECU prohibits driving of an electric motor by turning off power supply to the motor by a drive prohibition device, when a diagnosis part of a by-wire control circuit determines that a shift-by-wire system is abnormal or a monitor circuit determines that the by-wire control circuit is abnormal. In this case, the motor is stopped from rotating by execution of power supply phase fixation processing, by which a power supply phase of the motor is fixed without switchover, when the motor is driven to rotate at the time of determination of abnormality of the shift-by-wire system. Then the prohibition device prohibits driving of the motor by stopping the power supply to the motor.

Abstract: When electric power supply is started, an initial driving operation is performed to switch over a power supply phase of a motor in open-loop control. Initial learning processing is performed to learn a phase deviation correction value for the power supply phase relative to a count value of a pulse signal of an encoder. As a restraint caused by a shape of a detent mechanism, the motor need be rotationally driven so that a detent lever does not move in a negative direction beyond a bottom position of a P-range in the initial driving operation. In a case of performing the initial learning processing in the P-range in consideration of this restraint, the initial learning processing is performed by setting a rotation direction of the motor.

Abstract: A motor control apparatus that controls rotation of a rotor of an electric motor powered from an electric power source includes a learning portion that executes an initial drive learning process, and a controller that executes a normal drive operation to sequentially change an exciting phase of the electric motor based on a count value of a counter which is corrected by a correcting portion such that the rotor is rotated to a target position after an initial drive operation is finished. The learning portion re-executes the initial drive learning process after a predetermined condition is satisfied, when the initial drive learning process is failed.
