A motor control apparatus for a hybrid vehicle, wherein during operations of automatic start-up/stop control of the engine, at restarting of the engine when a start-up condition is satisfied, the control means controls to said electric motor so as to start up engine by the electric motor only, during operation of automatic start-up/stop control of the engine, at restarting of the engine when a start-up condition is not satisfied, a controller controls to drive a starter motor and an electric motor by outputting an engine activation signal so that the starter motor is always assisted by the electric motor during engine start. The electric motor is started by voltage supplied by the main battery. By such system, the engine and motor are not collectively controlled, and simplification of the system is achieved. Further, synchronism of the engine and motor is obtained and quietness at restart of the engine also results.

1. A control apparatus for a hybrid vehicle, having an electric motor which is directly connected with an engine mounted on the vehicle and has both driving and power-generating functions, comprising:a motor controller that executes automatic start-up/stop control of said engine, and in start-up of the engine starts the engine with a starter motor by operation of a key and by operation of said electric motor, wherein while the engine is stopped by operation of automatic start-up/stop control, at restarting of the engine when a start-up condition is satisfied, the controller starts the engine using only the electric motor, and while the engine is stopped by operation of the automatic start-up/stop control, at restarting of the engine when the start-up condition is not satisfied, the controller drives the starter motor and the electric motor by outputting an engine activation signal so that the electric motor assists engine restart after engine speed exceeds a predetermined speed.
