Abstract
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.
Claims6
A controller for a vehicle, wherein
- the vehicle includes:
- an engine as a drive source;
- a motor-generator as a drive source;
- and
- a battery that supplies power to the motor-generator,
- the controller comprising:
- a target engine torque calculating unit that calculates a target engine torque based on an accelerator operated amount, the target engine torque being a target value of a torque of the engine;
- a target motor torque calculating unit that calculates a target motor torque based on the accelerator operated amount, the target motor torque being a target value of a torque of the motor-generator;
- a permissible value calculating unit that calculates a booming noise permissible value based on an index value indicating a traveling state of the vehicle, the booming noise permissible value being an upper limit of a booming noise;
- a threshold calculating unit that calculates a threshold, the threshold being an upper limit of the torque of the engine used to limit the booming noise to the booming noise permissible value or less;
- and
- a controlling unit, wherein
- in a case in which the target engine torque is less than or equal to the threshold, the controlling unit controls the engine such that the torque of the engine becomes equal to the target engine torque, and controls the motor-generator such that the torque of the motor-generator becomes equal to the target motor torque, and
- 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 becomes greater than the target motor torque.
