针对某装备6挡双离合自动变速器的车辆，制定了传统两参数综合换挡规律，并分析了在该换挡规律控制下，车辆行驶在城市拥挤道路、紧急制动、加速超车、弯道和坡道等特殊工况时出现不合理换挡现象的原因。为减少不合理的换挡，综合考虑行驶环境和驾驶员意图，采用模糊控制方法，提出了基于传统两参数换挡规律的在线修正换挡规律。最后通过 AMESim-Simulink 联合仿真，对比了传统换挡规律和在线修正换挡规律在上述特殊工况下的控制效果，验证了在线修正换挡规律的有效性。%A traditional two-parameter comprehensive shift schedule is worked out for a car with six-gear dual clutch transmission, and the causes of unreasonable shifting happened with that shift schedule in special condi-tions, such as urban congestion roads, emergency braking, accelerated overtaking, curved road and ramp are ana-lyzed. For avoiding or reducing unreasonable shifting with concurrent consideration of driving environment and driver 's intension, an online corrected shift schedule based on two-parameter comprehensive shift schedule is proposed by using fuzzy control method. Finally through an AMESim-Simulink co-simulation, the control effects with both tradi-tional comprehensive shift schedule and online corrected shift schedule under above-mentioned special conditions are compared, verifying the effectiveness of online corrected shift schedule proposed.
