摘　　要：对“工程车辆四参数自动变速规律”进行了新的研究,由发动机油门开度和工作泵压力得出最佳换挡点,从而制订新的换挡策略,重点对其控制系统进行研究。根据四参数变速台架试验数据利用图解法,绘出了工程车辆四参数自动变速规律曲面图。以AT89C55WD单片机为主控芯片采用模块化设计,研制开发了四参数自动变速系统的电子控制单元(ECU——electronic control unit)。在硬件和软件两方面分别进行抗干扰设计,保证了自动变速控制器能在工程车辆恶劣的工作环境中稳定可靠的工作;进行了台架试验。结果表明,该控制系统能实现自动变速并进一步提高工程车辆传动系统的效率,达到节能增效的目的,对四参数自动变速控制技术在工程车辆上装机应用具有一定的参考价值。New research is conducted on four parameters automatic speed-changing regularities. Optimum shift point is obtained from engine throttle opening and work pump pressure,whence new shift strategy is worked out and its control system is studied in stress. Based on bench test data of four parameters speed-changing,a curve graph of four parameters automatic speed-changing regularity of construction vehicles is plotted. An electronic control unit for four parameters automatic speed-changing system is developed and anti-interference designs are provided for both hardware and software,which ensures stable and reliable work of automatic speed-changing controller in the rigorous work conditions of construction vehicles. Bench test shows that the control system could accomplish automatic speed-changing and further increase drive system efficiency of construction vehicles to reach the goals of energy saving and increased efficiency. The research is of referential values for on-board application of four parameters automatic speed-changing control technology to construction vehicles.
