ABSTRACT:
An electric heating apparatus for heating the passenger compartment of a motor vehicle, such as an automobile, having an internal combustion engine driving an electric power generator for charging a battery supplying power to electrical equipment on the vehicle includes a control system permitting actuation of the apparatus only when the engine reaches a predetermined rotational speed above which the generator is able to generate power. The air-fuel mixture supplied to the engine is regulated by a rotational speed control means in accordance with a control signal produced by a control circuit responsive to a temperature sensor detecting that the engine temperature is below a predetermined level and a voltage sensor detecting that the voltage produced at the neutral terminal of the power generator is higher than a predetermined value to increase the rotational speed of the engine and thereby the power generated by the power generator. A power supply switch responsive to the control signal is energized to cause power to be supplied to the electric heating element of a warm air generator for supplying heat to the passenger compartment until such time as the engine temperature rises above the predetermined level, the detected voltage drops below the predetermined value or the system is manually turned off by operation of the ignition switch or a system operating switch. The control system prevents over-discharge of the vehicle battery.
