摘要
在分析急松油门(Fast-Off)工况下自动变速车辆升挡机理的基础上,对传统的换挡控制策略进行优化,提出了Fast-Off工况下自动变速车辆的优化换挡控制策略。应用MATLAB软件建立了自动变速车辆仿真平台,在爬坡时的Fast-Off工况下,分别对传统的控制策略和优化控制策略进行仿真分析。结果表明,所提出的优化换挡控制策略能够提高车辆的动力性,改善车辆爬坡性能。
The conventional shift control strategy is optimized by analyzing the upshifl principle of a vehicle with automatic transmission under Fast-Off condition. The optimized shift control strategy under Fast-Off condition is presented accordingly for vehicle with automatic transmission. The simulation platform is constructed with MATLAB software for the AT vehicle. Conventional shift control strategy and optimized control strategy were simulated and analyzed in Fast-Off condition in uphill operation. The result indicates that the proposed strategy can improve the vehicle＇s power performance and hill-climbing capacity.
