摘要： A working machine such as a road milling machine of an asphalt paving machine has an automatic grade and slope control system that causes the machine to maintain a pre-selected grade and slope with respect to a reference without significant operator input. A calibration system employs a calibration controller to calibrate the automatic grade and slope control system. The calibration controller causes a current to be sent to a valve that operates a linear actuator that may be employed to change the attitude of the frame of the working machine. The calibration controller uses feedback from at least one sensor, such as a height-measuring sensor or a slope-measuring sensor, in an iterative process that determines the minimum current necessary to cause a change in the attitude of the frame of the working machine. Once this minimum value is determined, the system will establish the optimum settings for the automatic grade and slope control system to improve its efficiency and cause it to operate more smoothly.
摘要翻译：沥青摊铺机的道路铣床等工作机械具有自动等级和坡度控制系统，使得机器相对于参考线保持预先选择的坡度和斜率，而不需要大量的操作员输入。校准系统采用校准控制器校准自动坡度和坡度控制系统。校准控制器使得电流被发送到操作线性致动器的阀，该线性致动器可用于改变作业机器的框架的姿态。校准控制器在迭代过程中使用至少一个传感器（例如高度测量传感器或斜率测量传感器）的反馈，该迭代过程决定了引起作业机器的框架姿态变化所需的最小电流。一旦确定了该最小值，系统将为自动坡度和坡度控制系统建立最佳设置，以提高其效率并使其运行更加平稳。

摘要： A milling machine includes a milling assembly having a housing to which left and right end gates are attached, a controller, a right front lifting column, a left front lifting column and a rear lifting column. Elevation sensors are located at the front and rear of each of the end gates. The controller is operatively attached to the elevation sensors and to linear actuators within the lifting columns of the milling machine. The elevation sensor that is located at the front end of the right end gate will provide feedback to control the position of the right front lifting column, and the elevation sensor that is located at the front end of the left end gate will provide feedback to control the position of the left front lifting column. The elevation sensors that are located at the rear ends of the end gates are available, as selected by the operator, to provide feedback to control the positions of one of the right and left front lifting columns, as well as the rear lifting column.
