As an emerging technology improving fuel consumption, active grille shutter (AGS) has been applied in engine cooling system. For the reason of unreasonable matching method of grille opening and cooling fan, the problem of engine overcooling is widespread. As components with similar function of adjusting cooling air flow, the AGS and the cooling fan are separated from each other in parameter matching and operation which reduce cooling efficiency and fuel economy. To achieve precise cooling and improve fuel economy, a joint control strategy for AGS and cooling fan was proposed by using computational fluid dynamics. In order to verify the feasibility of the strategy, the fuel economy tests were carried out at 0 km/h, 90 km/h and 120 km/h, respectively. The results showed that the fuel consumption under the three working conditions was reduced by 0.01 L/100 km, 0.07 L/100 km and 0.13 L/100 km, respectively, indicating that the proposed strategy can significantly reduce fuel consumption.
