| Abstract: | Aimed at the problem that automatic transmission is hard to identify road surface,resulting in the problem that shift schedule is hard to suit the road,the vehicle modeling analysis was performed based on vehicle dynamics.The concept of equivalent slope was put forward to pick up the common factor of complex roads and discuss the shift schedule.Based on vehicle dynamic model,engine performance and vehicle transmission performance,vehicle shift strategy on special road was analyzed.The common factor of speci... |
