The invention discloses an engine water pump control method and device. The method comprises the steps that the real-time water temperature of an engine is obtained; if the real-time water temperature is smaller than or equal to a cold start threshold value, the real-time rotating speed and the real-time load of the engine are obtained; the working flow proportion value of a water pump is determined according to the real-time rotating speed and the real-time load; the starting duration of the water pump is determined according to the real-time water temperature, the real-time rotating speed and the real-time load; then the closing duration of the water pump is determined according to the starting duration and the real-time load; and finally the water pump is controlled to work according to the working flow proportion value, the starting duration and the closing duration. According to the engine water pump control method and device, the starting time and the closing time of the water pump are accurately calculated and distributed when warming-up operation is conducted, and therefore the heat dissipation power of the water pump can be well matched with the actual working condition of the engine, the actual heat dissipation requirement of the engine is effectively met, the purpose of accurately controlling the water pump to conduct accurate heat management on the engine is achieved, and the warming-up effect of the engine is guaranteed to the maximum extent under the condition that the engine does not have the overheating risk.
Description
technical field [0001] The invention relates to the technical field of vehicle water cooling systems, in particular to an engine water pump control method and device. Background technique [0002] As an important part of the vehicle water cooling system, the performance of the water pump directly affects the cooling effect of the vehicle engine. Mechanical water pumps and clutch-type water pumps are powered by the engine, and cannot actively adjust the flow rate to cool the engine reasonably; electronic water pumps are powered by batteries and can adjust the flow rate according to actual needs, but their reliability is not as good as that of mechanical water pumps. Therefore, a variable flow water pump that combines the characteristics of conventional mechanical water pumps and electronic water pumps has become a better choice. [0003] The variable flow water pump is an adjustable water pump powered by the engine. There is a maximum flow value at each speed. The maximum fl...
