摘要
根据电控机械式自动变速器起步性能指标及起步过程离合器转矩传递特性,提出了确定离合器目标接合速度的加权方法.该方法兼顾了驾驶员起步意图及自动变速器起步性能要求.模仿人工控制的特点,同时考虑液压油温度变化的影响,提出了基于误差峰值采样的自适应温度补偿的起步过程离合器接合速控制算法.实验表明,该算法既满足了3种典型起步工况(爬行起步、正常起步和急起步)的性能要求,又提高了系统对温度变化的适应能力.
The engagement-speed of clutch was determined with a weighted method based on the starting performance indices of AMT (automated mechanical transmission) and torque-transferring characteristics of clutch. In the method, the driver's intention and the requirements of starting performances are taken into consideration. A clutch engagement-speed control algorithm was proposed based on peak error sampling and adaptive temperature compensation. Experimental results show that the algorithm satisfies the requirements for three typical starting modes, namely, creeping, normal and abrupt start mode and improves the adaptability to temperature variation.
