A motor control apparatus for a hybrid vehicle with a diesel engine provides for a reduced compulsory regeneration time period so as to achieve enhancement of the fuel cost. The motor control apparatus includes a filter for collecting particulate matter in exhaust gas of the diesel engine, a compulsory regenerator for compulsorily regenerating the filter, and a battery charger for converting the output power of the diesel engine into electric power based on a charged state of the battery, and for charging the battery with the electric power. When the compulsory regeneration is executed, the supply of electric power to the battery by the engine is inhibited.
