Abstract: A motor control apparatus includes a by-wire control circuit for sequentially switching an energized phase of a motor. The by-wire control circuit pre-stores a first table defining an energized phase address corresponding to each address and a second table defining an energized phase corresponding to each energized phase address. When receiving a drive permission code from a second control circuit, the by-wire control circuit switches the energized phase in a correct order of driving the motor, by calculating an address for access to the first table based on the drive permission code, calculating an energized phase address corresponding to the address by referring to the first table, and determining the energized phase corresponding to the energized phase address by referring to the second table.

Abstract: A SBW-ECU switches over a shift range to a selected range by rotationally driving a motor to a target position corresponding to the selected range. When a direction of rotation of the motor is the same as a direction toward the target position and a difference between the target position and a present position is larger than a threshold value in a case that the selected range is changed during rotational driving of the motor, the target position is updated to a post-change target position. When the direction of rotation of the motor is opposite to the direction toward the target position or the difference between the target position and the present position is smaller than the threshold value in the case that the selected range is changed during rotational driving of the motor, the target position is updated to the post-change target position after completing the switchover to the pre-change selected range.

Abstract: A range switching device provides a feedback control for rotating a motor toward a target rotation position. When a target shift range is switched, the range switching device rotates the motor toward a target rotation position by sequentially switching power supply phases of the motor based on an encoder count value. When the motor rotates within a predetermined stop range, the feedback control ends and a power supply to the motor is stopped. However, if the motor has not rotated to the target rotation position after a predetermined time has elapsed from the stopping of the power supply to the motor, an open drive is performed, in which the power supply phase of the motor is sequentially switched by open-loop control and the motor is rotated in small and/or minute steps toward the target rotation position. In such manner, position accuracy of the shift range switching is improved.

Abstract: A shift position switching controller determines whether the responsiveness for switching the shift position to an other-than-N position will be affected by a reduction of an N position check time and keeps the N position check time unchanged from a normal value if a current shift position is a D position or if a vehicle speed is equal to or greater than a preset value. Alternatively, the shift position switching controller determines whether the responsiveness of the controller will be affected by reducing the N position check time, and sets the N position check time to a shorter-than-normal value if the current shift position is a D position and the vehicle speed is equal to or greater than the preset value.

Abstract: A range switch device has a range switch control without an abutment control of a motor. The range switch control detects an encoder count at a slack removed rotation position of the motor during a rotation to a target rotation position at a shift range switch time. Then, the range switch control sets the target rotation position based on the slack removed rotation position of the motor and a by-design rotation amount of the motor, in which the slack removed rotation position is detected by an encoder count that marks an output change start time of a rotation sensor and a by-design rotation amount between pre- and post-switching rotation positions regarding pre- and post-switching shift ranges.

Abstract: To a first electronic control unit, three or more sensors excluding one predetermined sensor are connected. To a second electronic control unit, two sensors, which include one common sensor, of the three or more sensors, are connected. When the first electronic control unit does not determine that a sensor in a normal state is present among the three or more sensors, and the second electronic control unit determines that both of the two sensors are in the normal state, the electronic control unit controls the brake circuit based on the operation amount detected by at least one of the predetermined sensor or the common sensor.
