Abstract
A hybrid car comprises an electric motor for driving the vehicle, an internal combustion engine for power generation, and auxiliary machineries such as an air conditioner. If an air conditioner operating switch is turned on while the hybrid car is running, engine operation is started after the temperature of a catalyst is increased to a predetermined value, and the air conditioner for use as an auxiliary machinery is driven by the engine. The hybrid car is improved in cruising range and power performances as compared with an arrangement in which the auxiliary machineries are driven by means of a battery which is connected to the electric motor.
