    • A method for resetting a calibration of a sensor operating out-of-range in a hydraulic actuation system is provided. The hydraulic actuation system includes a pump, a reservoir, a plurality of work-ports, a plurality of sensors, and a valve system, and a controller for regulating the hydraulic actuation system based on fluid flow demand and sensed pressures. The method includes detecting the sensor operating out-of-range, opening all work-ports to the reservoir, resetting all sensors to reservoir pressure, supplying all sensors with fluid at maximum pump pressure, and sensing the maximum pump pressure at each sensor. Additionally, the method includes determining an average pressure value across all sensors, assigning the determined average pressure value to the sensor that is operating out-of-range, and resetting the calibration of the sensor that is operating out-of-range based on the reservoir pressure and the average pressure values.
    • 提供了一种用于重置在液压致动系统中操作超出范围的传感器的校准的方法。 液压致动系统包括泵,储存器,多个工作端口,多个传感器和阀门系统,以及用于基于流体流量需求和感测压力来调节液压致动系统的控制器。 该方法包括检测超出范围的传感器,将所有工作端口打开到储存器,将所有传感器重新设置为储存器压力,为所有传感器提供最大泵压力下的流体,并感测每个传感器的最大泵压。 此外,该方法包括确定跨所有传感器的平均压力值,将所确定的平均压力值分配给正在运行超出范围的传感器,以及基于所述传感器的超范围重新设定运行在超范围内的传感器的校准 储层压力和平均压力值。
