Abstract

PURPOSE:To improve fuel consumption of an engine and decrease its warm up time, by performing correction with a correction device through output from an operation detector of a room heater, providing said correction device in an independent driving gear of a water pump and removing unnecessary driving operation of the water pump when the heater is not operated. CONSTITUTION:A signal of a temperature sensor 14 is input to a temperature detector circuit 16, and a circuit 16 outputs to an arithmetic output circuit 17 by said signal, in accordance with this output a circuit 17 calculates a required current for a motor 13 to output to a correction device 11 through a control circuit 18. The device 11, when a room heater 6 is operated, adds a correction signal to an output signal of the circuit 18 to output a large current to a driving gear. This output current is applied to a relay 19 of the motor 13 and a transistor 21 connected to a rotary control coil 20. Accordingly, the motor 13 is started while the transistor 21 flows a control current in the coil 20, then rotary speed of a water pump can be controlled to a prescribed speed.
