基于事件触发器的AMT换挡控制策略研究

摘要

鉴于车辆油门开度和发动机转矩的急速变化容易引起频繁换挡，提出了采用事件触发器来识别油门开度变化率，并作为控制参数的控制策略，依据事件触发器的开闭可防止车辆频繁换挡。试验结果表明，所提出的控制策略能有效减少频繁换挡现象的发生，提高车辆的乘坐舒适性。%In view of that the rapid change of throttle opening and engine torque is prone to cause frequent gear shifting, a control strategy is proposed of using an event trigger to identify the changing rate of throttle opening and take it as control parameter. Frequent gear shifting can be prevented by means of the opening and closing of e-vent trigger. The results of test show that the control strategy proposed can effectively reduce the occurrence of fre-quent shifting, enhancing the ride comfort of vehicles.
