摘 要: 文章针对搭载双离合自动变速器(dual clutch transmission,DCT)的车辆制定了传统的两参数综合换挡规律,分析了此换挡规律在不同的驾驶意图、行驶环境下出现不必要换挡的原因。为减少不必要的换挡,综合考虑驾驶员意图以及行驶环境,通过模糊控制方法确定了换挡规律修正因子。建立仿真模型,并对比分析了传统换挡规律和修正换挡规律在不同驾驶意图和行驶环境下的换挡情况,仿真结果表明该修正换挡规律能够有效消除不必要的换挡现象。 For the traditional two-parameter comprehensive shift schedule of the car with dual clutch transmis- sion(BCT), the causes of unnecessary shifting happened under different driver's intension and driving envi- ronment are analyze& To avoid this, the correction factor based on two-parameter comprehensive shift sched- ule is proposed by using fuzzy control metho& Based on the simulation model, the traditional comprehensive shift schedule and the corrected shift schedule are compared under different driver's intension and driving en- viromnent, verifying the effectiveness of the corrected shift schedule orooosed.
