The invention discloses a control system for realizing intelligent start / stop of the water pump of a vehicle. The control system comprises a vehicle main control unit, a detection module for detecting the water temperature of an engine, and an execution module for executing the control command sent from the vehicle main control unit to control start / stop of a water pump, wherein the signal output end of the detection module is connected with the signal input end of the vehicle main control unit, and the signal input end of the execution module is connected with the control signal output end of the vehicle main control unit. The inventive control system can intelligently control start / stop of the water pump according to the water temperature of the engine, reduce power consumption and oil consumption, and prolong the service life of the water pump and the engine. The control system is suitable for control on the water pump in a cooling water circulation system in various automobiles.
Description
technical field [0001] The invention belongs to the field of automobiles, and relates to a control system in the circulation process of vehicle cooling water, in particular to a control system for realizing intelligent start and stop of vehicle water pumps. Background technique [0002] The cooling water circulation system of the automobile engine pumps the cooling water in the water tank through the water pump, and then flows into the radiator for circulation and cooling. In the prior art, the working principle of starting and stopping the water pump is as follows: figure 1 As shown: the crankshaft wheel 1 is driven by the engine to rotate, the crankshaft 1 is connected to the first auxiliary wheel 21 through the belt, the first auxiliary wheel 21 is connected to the water pump 3 through the belt, and the water pump 3 is connected to the crankshaft wheel 1 through the second auxiliary wheel 22, thus forming power Finally, the power is transmitted to the water pump 3 to mak...
