摘要： A control device (10) for a vehicle (100), includes an operation controller (14) that controls operations of a rotating electric machine (140) mounted to the vehicle, a first torque detector (11) 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 (12) 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 (13) 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 is configured to perform 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.

摘要： A rotating electrical machine (10) includes a stator (30) equipped with a stator winding (31), a rotor (20) arranged to face the stator, a housing in which the stator and the rotor are disposed, and a coolant supply unit (70). The coolant supply unit is located vertically above the stator and the rotor in the housing in a condition where the rotating electrical machine is mounted in place. The coolant supply unit works to deliver liquid coolant into the housing. A coolant guide (A2, 83) is provided to direct the coolant, as supplied from the coolant supply unit, into an air gap between the stator and the rotor in the housing.

摘要： A control device (50) includes a switching control unit (55) and a difference acquisition unit (64). The switching control unit performs switching control that increases braking torque of a braking device while decreasing braking torque of a rotating electrical machine, when a vehicle is decelerated. The difference acquisition unit acquires a braking torque difference indicating a difference between braking torque required for keeping a stopped state of the vehicle and braking torque of the braking device, when the vehicle is stopped. After the information acquisition unit detects the stopped state of the vehicle, the switching control unit corrects output torque of the rotating electrical machine based on the braking torque difference.

摘要： A control apparatus (50) of a motor generator (42) is connected to an internal combustion engine (41) and includes: an estimation unit (52) that estimates an estimated torque pulsation that is an estimation value of torque pulsation of the internal combustion engine; and a control unit (53) that controls the motor generator to reduce generated power and suppress decrease in a rotation speed of the internal combustion engine, when a negative torque that obstructs rotation of the internal combustion engine is generated in the estimated torque pulsation of the internal combustion engine.
