Abstract: This paper is aiming at the hill start assist control research for automated mechanical transmission light vehicle with the hill start assist system. According to the working characteristics of the hill start assist system, the dynamics of the vehicle launch process on a slope is analyzed. The control strategy of the hill start assist for automated mechanical transmission vehicles is carried out and the control software is designed. Finally the vehicle is tested on different slopes. The test results show that the research method can meet the requirements of automated mechanical transmission vehicle launches on different slopes, and the vehicle launches smoothly on the slopes without slipping. The hill start assist system has strong practicability.
