A controller controls a hybrid electric vehicle. The hybrid electric vehicle includes an engine, a motor arranged in a power transmission path between the engine and a drive wheel, and a clutch arranged in the power transmission path between the engine and the motor. The controller idles the engine in accordance with a target engine rotation speed and operates the motor in accordance with a target motor rotation speed when the clutch is in a disengagement state. When the clutch is in the disengagement state and the engine is idling, the target motor rotation speed is less than the target engine rotation speed.

Controller for hybrid electric vehicle and method for controlling hybrid electric vehicle

Electric devices of a vehicle are divided into groups according to a magnitude of electric power used by each of the electric devices. The number of the groups is smaller than the number of the electric devices. A controller for the vehicle stores in advance different correction amounts respectively associated with the groups. The controller is configured to, when the number of operating ones of the electric devices belonging to the same group is equal to or greater than a predetermined specified number, perform an increase process of increasing an engine rotation speed of an internal combustion engine by the correction amount associated with the group in which the number of the operating ones of the electric devices is equal to or greater than the specified number.
