Abstract:

The design of shift schedule is of great importance for the drivability of vehicular automatic mechanical transmission. Currently, the most widely used is two-parameter shift schedule, but it ignores the influence of dynamic conditions and ramp conditions. In this paper, a three-parameter power shift schedule based on vehicle speed, acceleration and throttle angle has been proposed, which makes the vehicle have the best performance in all kinds of slope surface. Then the vehicle model is established by Cruise and Matlab/simulink. The simulation results show that the three-parameter power shift schedule can effectively enhance the vehicle dynamic performance.
