Abstract: Aiming at the problem of driving wheel slip of automated mechanical transmission (AMT) vehicles starting on low adhesion road surface, taking the vehicle equipped with 6 AMT light truck as the research object, judging the skid of driving wheel on low adhesion road surface according to AMT system and anti-lock brake system (ABS) wheel speed, and conducting dynamic analysis of vehicle starting on low adhesion road surface. The starting control strategy of AMT vehicles with low adhesion road surface is proposed, corresponding control software is designed, and the real vehicle test is verified on the low adhesion road surface. The test results show that the research method can well meet the requirements of AMT vehicles with low adhesion road surface starting, effectively avoid driving wheel skid, improve vehicle handling stability, and have strong practicability.
