Title: ENGINE CONTROL DEVICE, ENGINE UNIT, AND VEHICLE
Abstract:
The purpose of the present invention is to reduce the size of a battery while ensuring ease of engine startup. This engine control device is provided with: a power supply unit configured so as to perform control for supplying the power of the battery to an electric motor so as to cause the electric motor to generate driving force in at least part of a deceleration period; a battery state acquisition unit for acquiring a voltage value and/or a current value of the battery when the power of the battery is supplied to the electric motor; a permission determination unit for determining, on the basis of the acquired voltage value and/or current value of the battery, whether or not to permit the engine to stop idling; and an engine control unit for controlling the engine so as to prohibit transition from the deceleration period to a state in which the engine has stopped idling when the engine is not permitted to stop idling.
