Abstract:
In the plateau area, the performance of internal combustion engine vehicles will be affected by the altitude. Based on the analysis of the fact that engine performance changes with the altitude, a simulation model of AMT vehicles' power transmission system is established, and the dynamic gear shift control schedule of AMT vehicles in plateau environment is studied. By modifying the control parameters of the optimal-power shift schedule, the formulation method of dynamic shift schedule based on different altitudes is proposed and simulated. The simulation results show that the proposed plateau dynamic shift schedule can acclimatise AMT vehicles to the plateau environment, and improve the dynamic performance of AMT vehicles obviously.
