Jiang Ming Yang Yan Li Yingyou Gu Cheng Xv Heng

Abstract：Cost reduction and efficiency improvement are the driving force for the automobile industry to move forward. Based on the known principle of fuel saving at vehicle idle speed， this paper starts from the aspect of vehicle control software， develops V model based on vehicle software， optimizes the vehicle software control model， and controls the vehicle hardware to open idle speed and fuel saving during operation. Through the comparison and verification of real vehicle experiments， it is concluded that the design conforms to the expected function to provide software assistance for reducing fuel consumption of the vehicle.

Key words：pattern design， idle fuel-efficient， controller， clutch
