ABSTRACT:
An ice melting system for a motor vehicle supplies a heater incorporated in a windshield with electric energy which is generated by a generator that is drivable by an engine on the motor vehicle. A voltage which is obtained by dividing an output voltage from the generator is applied as a control input voltage to a voltage regulator which controls the output voltage of the generator. When the voltage regulator is supplied with a control input voltage which is lower than when a battery on the motor vehicle is charged, the voltage regulator increases a current supplied to a field coil of the generator, thus enabling the generator to increase the output voltage thereof. Therefore, the heater is supplied with a larger amount of electric energy to melt ice on the windshield efficiently.
