Abstract
A motor control apparatus is combined with an internal combustion engine and an electric motor to form a vehicle-propelling system. The motor is connected to a crank shaft of the engine and has both driving and power-generating functions. The motor control apparatus includes an automatic start-up/stop control device having automatic start-up control and automatic stop control sections. When the vehicle is started with a key, the automatic start-up control section uses the starter motor and always gains assistance from the electric motor in starting the vehicle. Only the automatic start-up control section controls start up of the electric motor, which prevents a noise occurring when a ring gear is engaged with a starter motor gear. This operation improves the quietness of the engine. This arrangement enhances discharge of exhaust gas.
