Abstract
Starting with the basic control principles of the two main pressures for gearshift in AT—— pressure at throttle valves and speed control pressure, this paper expatiates on the controlling and regulating process of the output characteristics and discusses the influential factors in the regulating process. Through the analysis, this paper points out the key to the design of hydraulic control system, emphasizes that the coordination and restriction of pressure at throttle valves and speed control pressure are the importance guarantee for the realization of optimal gearshift characteristics.
