A vehicle includes an engine, a rotating electric machine, a high-voltage power line, a high-voltage battery, an inverter, a capacitor, an electronic control unit, a low-voltage battery, an alternator, and a low-voltage power line. The capacitor is connected to the high-voltage power line. The electronic control unit is configured to control the engine such that the engine is operated and the alternator supplies electric power to the low-voltage power line in a case where the possibility of the occurrence of a collision of the vehicle is detected. The electronic control unit is configured to perform control such that the capacitor discharges a residual electric charge in a case where the possibility of the occurrence of the collision of the vehicle is detected or in a case where the occurrence of the collision of the vehicle is detected.

Vehicle with capacitor discharge control

A vehicle includes an engine, an automatic transmission, a second clutch for engine disconnection, a rotating electric machine, a first clutch for rotating electric machine separation, and an electronic control unit. The electronic control unit switches the first clutch from a release state to an engagement state in a case where a collision of the vehicle occurs, the first clutch is in the release state, and a rotation speed of the rotating electric machine is higher than an input shaft rotation speed of the automatic transmission. In a case where the collision of the vehicle occurs, the first clutch is in the release state, and the rotation speed of the rotating electric machine is lower than the input shaft rotation speed of the automatic transmission, the first clutch is maintained in the release state.

Control device and control method for vehicle

The rotating shaft of the motor is connected to and disconnected from the first coupled rotating shaft, the crankshaft of the engine, and the drive shaft is connected to and disconnected from the second coupled rotating shaft and the third coupled rotating shaft. Thereby, the connection state when a power is output to the drive shaft can be increased and the power to the drive shaft can be output in a more efficient connection state in comparison with only connecting and disconnecting the rotating shaft of the motor to and from the first coupled rotating shaft and the crankshaft of the engine.
