本文论述了换档规律的重要性,研究了如何寻求最佳换档规律的方法,以及实现最佳燃料经济性换档规律与最佳动力性换档规律的途径。因全液压操纵系统只能实现一个换档规律,故将红旗CA—770自动操纵系统改进为电子控制的液压操纵系统,实现了微处理机控制。试验表明:不仅提高了汽车的燃料经济性而且提高了动力性。这为微处理机在国内自动换档在汽车上的应用提供了一定的经验。同时试验表明,稳定与非稳态下换档规律有较大差异,油门越大,加速强度越大,这种偏差越大。换档是非稳定过程,应以非稳态来研究其最佳规律,而微处理机的引入自动换档系统为实现理想的三参数控制创造了良好的前景。
This article discusses the importance of the shift pattern, studies how to find the best shift pattern, and how to achieve the best fuel economy shift schedule and the best power shift schedule. Due to full hydraulic control system can only achieve a shift rule, so the red flag CA-770 automatic control system to improve the electronic control of the hydraulic control system to achieve the microprocessor control. Experiments show that: not only improve the car’s fuel economy but also improve the dynamic. This microprocessor for the domestic auto shift applications in the car has provided some experience. At the same time, the test shows that there is a big difference in the shift pattern between steady and unsteady states. The bigger the throttle is, the larger the acceleration is and the larger the deviation is. Shift is an unstable process, and its best rule should be studied in unsteady state. The introduction of microprocessors into the automatic shift system has created a good prospect for the realization of the ideal three-parameter control.
