Abstract: In oder to study vehicle thermal management technology,an electromagnetic clutch water pump and its control strategy from the perspective of the vehicle are optimized. Through the vehicle test, it focuses on verifying the influence of the electromagnetic clutch water pump and its control strategy before and after optimization on the thermal management and economy of the whole vehicle. The test results show that the optimized electromagnetic clutch water pump and its control strategy can meet the thermal management needs of the whole vehicle. The fuel consumption of the whole vehicle at 100 km high speed in plain area has been reduced by 1%.

Keywords:electromagnetic clutch pump; vehicle thermal management; fuel consumption
