自动变速器智能换档规律的制定与仿真

Design and Simulation for Intelligent Shift Schedule of Automated Mechanical Transmission

考虑整车的运行状况、行驶路况及驾驶员的驾驶习惯等因素,根据某型号的整车相关参数、发动机的速度特性及整车滑行阻力试验数据,制定智能换档规律。利用Matlab/Simulink仿真模拟,验证了该换档规律的可行性。并表明这种换档规律可以针对不同路况实现最佳动力性或者最佳燃料经济性,保证了汽车的最佳性能。

Considering the vehicles＇ running state, road conditions, the driver＇s driving habits, anti so on, according to a type of vehicle parameters, the speed of the engine, vehicle characteristics and vehicle traveling resistance curve, the intelligent shift schedule is designed. Simulation on Matlab/Simulink verifies this shift schedule is feasibility, also imticates that this shift schedule can achieve the best performance in different road or the best fuel economy, and can ensure the vehicle＇s besl performance.
