| 摘 要： | 为提高装备自动变速器的越野汽车换挡控制系统对复杂路况的自适应能力,在基本模糊控制模块基础上,建立了具有两级递阶结构的越野车自适应模糊换挡控制系统.基本模糊控制模块将油门开度、车速和加速度3参数进行模糊化和模糊推理,实现挡位决策;自适应控制模块按照检测的车速和加速度对直线行驶阻力和附着力进行在线辨识,并由此进行量化因子的自调整.仿真结果表明所设计的模糊控制系统具有良好的自适应能力.

| Abstract: | Based on a basic fuzzy control module, a two-stage adaptive fuzzy control system for the automatic transmission of an off-road vehicle is established for improving the adaptability of the control system in off-road vehicle to complex road conditions. The three parameters of throttle opening, vehicle speed and acceleration are fuzzified by basic fuzzy control module and the shift position is decided through fuzzy inference. The running resistance along straight line and adhesive force are identified online by adaptive fuzzy control module according to the measured vehicle speed and acceleration, and the adaptive regulation on normalized factors is conducted. The simulation results show that the proposed adaptive fuzzy control system has good adaptability. |
