When a vehicle collision is detected, a electric connection between a power supply and an input stage of an inverter is switched to the disconnected condition. Then, when a rotation speed of an alternating current motor is higher than an allowable rotation speed or a terminal voltage of a storage unit provided at the input stage is higher than an allowable terminal voltage, an exciting current command value is set at a value other than zero and a torque current command value is set at zero, and when the rotation speed is equal to or lower than the allowable rotation speed and the terminal voltage is equal to or lower than the allowable terminal voltage, both command values are set at zero. An exciting current component and a torque current component of an alternating current supplied from the inverter to the motor are controlled according to the set command values.

Control apparatus and control method for vehicle

A power frequency distribution predicting unit predicts the power frequency distribution of a vehicle in a case where the vehicle travels a route with reference to the history of the vehicle power Pv when the vehicle traveled the route in the past. An operation condition setting unit sets the range of the required vehicle power Pvto operate the engine as an engine operation condition for controlling the energy balance between generated power and generated electric power of an electric rotating machine in a case where the vehicle travels the route to be at a preset value according to the power frequency distribution predicted by the power frequency distribution predicting unit. An operation control unit controls the operation of the engine according to the range of the required vehicle power Pvto operate the engine set by the operation condition setting unit.
