摘要： A controller for a vehicle includes a controlling unit. In a case in which the target engine torque is less than or equal to a threshold, the controlling unit controls the engine such that the torque of the engine becomes equal to the target engine torque, and controls a motor-generator such that the torque of the motor-generator becomes equal to the target motor torque. Also, in a case in which the target engine torque is greater than the threshold, the controlling unit controls the engine such that the torque of the engine becomes less than or equal to the threshold, and controls the motor-generator such that the torque of the motor-generator increases.

摘要： A controller for a vehicle includes a target traveling torque calculating unit, a target torque calculating unit, and a torque controlling unit. The target torque calculating unit is configured to execute an increasing process that increases, on condition that the target traveling torque is greater a threshold, a ratio of the target engine torque to the target traveling torque as compared to a case in which the target traveling torque is less than or equal to the threshold. The threshold is less than a maximum output value, which is a maximum value of a torque that can be generated by the motor-generator.
