Abstract
A motor control apparatus for a hybrid car is capable of reducing a spin of the wheel driven by the motor. The hybrid car comprises an engine driven wheel driven by an engine and a motor driven wheel to be driven by a motor for driving the wheel not driven by the engine. The hybrid car has an engine, a front wheeldriven by the engine, a generatorconnected to this engine and driven thereby, an electric motorfor driving the rear wheelusing power provided by the generator without being driven by the engine, and a controllermounted on the car to control the output of this electric motor. The controllercontrols the field currents of the electric motor and generator in such a way that the driving torque of the motor driven wheel to be driven by the electric motor is smaller than the driving torque of the engine driven wheel to be driven by the engine, thereby ensuring traction and car stability.
