By studying a 1.5 L turbocharged gasoline direct injection engine and analyzing its cooling system structure, this paper presents an electronic water pump control system and designs the control strategy based on the vehicle environment. Afterwards, the calibration and test verification are carried out. Experiment results show that the control strategy design presented in the paper can help the electronic water pump work accurately and timely under different engine working conditions, meanwhile, it can meet the requirement of cooled and pressurized gas temperature and turbocharger, proving feasibility of this control strategy.
