Abstract: A range switching device may switch a shift range despite resetting and restarting of a controller. When the controller is reset and restarted during a switching operation of the shift range and the shift range before or after being switched is a P range, the controller controls a motor to rotate the motor until a range switching mechanism abuts against a first limit position of a movable range of the range switching mechanism and learns a rotation position of the motor as a reference position of the motor. When the shift ranges before and after being switched are the ranges other that the P range, the controller controls the motor to rotate until the range switching mechanism abuts against a second limit position of the movable range and learns the rotation position of the motor as the reference position.

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 device is provided with a control circuit and a driving circuit. The control circuit switches over a current supply phase of the motor in a predetermined angular rotation of the rotor a first switching number of times in an acceleration range. The control circuit switches over the current supply phase of the motor in the predetermined angular rotation of the rotor a second switching number of times in a stationary rotation range in a specific condition that the rotation speed of the rotor is between a predetermined first threshold value and a predetermined second threshold value. The control circuit sets the second switching number to be smaller than the first switching number. In the acceleration range, the switching number is relatively large and hence a sufficient driving torque is applied to the rotor. In the stationary rotation range, the switching number is relatively small and hence the control circuit 61 needs to operate less, a current supply period for the motor is shortened and heat generation is suppressed.

Abstract: An actuator control apparatus including a by-wire control circuit, a monitor circuit, a drive determination section, and a prohibition section is provided. The by-wire control circuit electrically controls an actuator acting as a drive source of an on-board apparatus. The monitor circuit monitors whether or not the by-wire control circuit is normally operating. The monitor circuit is provided separately from the by-wire control circuit. The drive determination section determines prohibition and permission of driving the actuator. The prohibition section prohibits the actuator from being driven when the permission of driving the actuator is not determined by the drive determination section. The prohibition section also prohibits the actuator from being driven when the monitor circuit determines that the by-wire control circuit is not normally operating.
