摘要
分析了PWM电液比例溢流阀的工作原理与控制原理,完成了其控制器的硬件电路和软件设计。该控制器采用闭环控制,通过控制高速开关阀PWM信号占空比实现系统压力调节,控制精度高、实时性好,适合车辆动力换挡油压控制。
The principle and control of the PWM digital proportional relief valve were analyzed, and the controller was designed including the hardware and software. Using the closed loop control theory, the controller can automatically change the system pressure by controlling PWM signal duty cycle of the high speed switching valve. The PWM digital proportional relief valve system has good precision and real time, can be used to control pressure during the vehicle power shift.
