【摘要】 提出了AST自动同步换挡系统及其自动换档策略.通过油门踏板分析出驾驶员意图,将其转换为本系统的控制指令:加速度.并通过制定合理的换挡策略,综合控制节气门与变速器,用闭环控制来跟随加速度指令,从而实现汽车动力性、舒适性与燃油经济性自动换挡.在Matlab仿真软件中搭建了自动同步换挡系统的意图识别、换挡策略、汽车动力模型各模块,通过仿真证明了本同步换挡系统及换挡策略的可行性.更多还原

【Abstract】 Automatic synchronistical transmission(AST) and its scheme were studied.Driver′s intention is translated into the acceleration,the instruction of this system.Through a reasonable gear-shifting strategy and cooperation of throttle and gear-box,the motor follows the instruction of acceleration by closed loop,employing optimization for power,comfort and economy performance.The structure is proved effective in simulative test by building the AST system include intention analysis module,gear-shifting strategy module and motor power module.更多还原
