Abstract: A shift range control apparatus switches shift ranges by controlling a drive of a motor. The shift range control apparatus is provided with a motor drive controller and an actual range determination portion. The motor drive controller is capable of switching between at least two control modes as motor control modes that are modes in which the motor is controlled. The actual range determination portion determines an actual shift range, based on a requested shift range and the motor control modes.

Abstract: A control device for a vehicle includes an operation controller that controls operations of a rotating electric machine mounted to the vehicle, a first torque detector that detects a traveling torque which is a braking/driving torque to be output from the rotating electric machine when the vehicle is traveling, a second torque detector that detects a standstill torque which is a braking/driving torque to be output from the rotating electric machine upon the vehicle coming to a stop, and a waveform setter that sets a stop waveform which is a waveform indicating a time variation in the braking/driving torque output from the rotating electric machine from the traveling torque to the standstill torque. The operation controller performs a stop process that is a process to bring the vehicle to a stop while changing the braking/driving torque output from the rotating electric machine in accordance with the stop waveform.

Abstract: A control apparatus is mountable to a vehicle including an electric motor, a lock mechanism, and an actuator apparatus. The control apparatus controls the electric motor and a shift-by-wire system provided in the vehicle. The shift-by-wire system performs switching to shift ranges of the vehicle including a shift range and a non-parking range other than the parking range. The control apparatus drives the actuator apparatus to release the lock on the power transmission mechanism by the lock mechanism based on the shift range of the shift-by-wire system being switched from the parking range to the non-parking range. The control apparatus performs torque correction control in which an output torque of the electric motor is corrected such that a load acting on the lock mechanism from the power transmission mechanism is reduced based on the shift range of the shift-by-wire system being switched from the parking range to the non-parking range.

Abstract: A control apparatus for a vehicle includes an offset torque calculator configured to perform calculation of offset torque to be applied to at least one wheel of the vehicle. The offset torque is required to stop the vehicle on a sloping road having a predetermined gradient. The control apparatus includes a motor controller configured to, for stopping the vehicle on the sloping road having the predetermined gradient, perform control of causing output torque of the motor-generator to asymptotically approach the offset torque.

Abstract: A first engagement member includes a first meshing portion and rotates integrally with a first shaft. A second engagement member includes a second meshing portion configured to mesh with the first meshing portion and rotates integrally with a second shaft. An electric clutch device drives the first engagement member via a pressing member that extends and contracts in response to drive of a clutch actuator. When the electric clutch device is to be engaged, the first shaft command computation unit sets the first shaft rotation speed command value to be smaller than the rotation speed of the second shaft. Further, after the rotation speed of the first shaft matches the first shaft rotation speed command value, the first shaft command computation unit sets the first shaft rotation speed command value to be gradually closer to the rotation speed of the second shaft.

Abstract: A shift range control device is provided for a shift range switching system that includes a motor having winding sets and a motor rotational angle sensor. The shift range control device includes controllers configured to control switching of a shift range by controlling drive of the motor. Each of the controllers is provided to corresponding one of the winding sets, and is configured to acquire a motor rotational angle signal from the motor rotational angle sensor and calculate a motor angle, control drive of the motor by controlling a current supply to the corresponding one of the winding sets to make the motor angle become a target rotational angle corresponding to a target shift range, and drive the motor by sequentially switching a current-supplied phase for each predetermined period without using the motor rotational angle signal when the motor rotational angle signal is in fault.

Abstract: A shift range control device switches a shift range by controlling the driving operation of a motor. When a difference between a target angle at which the motor is to be stopped and an actual angle becomes smaller than an angle determination threshold, the shift range control device switches from a feedback control to a control with a fixed duty. When the motor reverses, the shift range control device switches from the control with the fixed duty to a stationary phase energization control for energizing a stationary phase of the motor.

Abstract: A shift range control device switches a shift range by controlling the driving of a motor. An angle calculation unit acquires a motor rotation angle signal outputted from a motor rotation angle sensor that detects the rotation position of the motor, and calculates a motor angle. A signal acquisition unit acquires an output shaft signal, which is outputted from an output shaft sensor for detecting the rotation position of an output shaft through which the rotation of the motor is transmitted. A value of the output shaft signal changing in steps in accordance with the rotation position of the output shaft. A target setting unit sets a motor angle target value by correcting, in accordance with a speed of the motor at the timing at which the acquired output shaft signal changes, a pre-correction motor angle target value that is set on the basis of a target shift range and a change point at which the output shaft signal changes. A drive control unit controls driving of the motor so that the motor angle reaches the motor angle target value.

Abstract: An output shaft receives transmission of a driving force of a motor. A valley forming member has valley portions correspondingly to shift ranges and rotates integrally with the output shaft. An engaging member is biased with a biasing member in a direction to be fitted to a valley portion and is configured to be fitted to a target valley portion, which is a valley portion corresponding to a target shift range. The motor control unit performs a control to drive the motor. The motor shaft, which is a rotary shaft of the motor, and the output shaft have a play therebetween. The motor control unit determines a motor target position to locate the engaging member at a position shifted by a predetermined amount before the center of the target valley portion in the driving direction.
