Abstract
A controller for a vehicle executes, when an ignition switch is turned off before an engine speed increases to an autonomous speed that is a speed allowing for autonomous operation of an engine, an increase process that increases the engine speed to greater than or equal to the autonomous speed, and a stop position control that stops a piston at a predetermined position in a cylinder through regenerative braking that converts rotational energy of a crankshaft of the engine into electric power with a motor generator after the increase process is completed.
Claims5
A controller for a vehicle, the vehicle including an engine provided with a cylinder and a motor generator connected to the engine, the controller comprising:
- processing circuitry, wherein
- the processing circuitry is configured to execute:
- when an ignition switch is turned off before an engine speed increases to an autonomous speed that is a speed allowing for autonomous operation of the engine, an increase process that increases the engine speed to greater than or equal to the autonomous speed;
- and
- a stop position control that stops a piston at a predetermined position in the cylinder through regenerative braking that converts rotational energy of a crankshaft of the engine into electric power with the motor generator after the increase process is completed.
