Abstract
A hybrid electric vehicle includes an engine, a motor, a clutch provided between the engine and the motor, a battery for charging regenerative electric power of the motor, and a control device that controls the engine, the motor, and the clutch. The control device includes a charge determination unit that determines whether the battery is chargeable when there is a deceleration request, and a deceleration control unit that executes, in a negative determination, a first deceleration process to decelerate the hybrid electric vehicle by friction torque of the engine, and executes, in a positive determination, a second deceleration process to decelerate the hybrid electric vehicle by regenerative torque of the motor. In the second deceleration process, the deceleration control unit causes the motor to output the friction torque at a rotational speed of the engine corresponding to a rotational speed of the motor as the regenerative torque.
