| Abstract: | The paper designed a cooling system of the proportional valve controlled by ECU on the heavy vehicle engine.Based on PID theory,the control program optimized the valve control methods and used the method of program module.As an important parameter,by comparing the environment temperature to the engine coolant temperature to control the proportional valve,so,it can adjust the rotate speed of water pump and fan motors.The system improved on the cooling method and advanced the cooling intensity. |
