Abstract

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.
