摘要： A milling machine may have a frame, a milling drum attached to the frame, and ground engaging tracks that support the frame and propel the milling machine in a forward or rearward direction. The milling machine may have at least one actuator connecting the frame to at least one of the ground engaging tracks. The actuator may adjust a height of the frame relative to at least one of the tracks. The milling machine may also have a non-contact leg-height sensor attached to the frame. The sensor may generate a signal indicative of a height of the frame relative to at least one of the tracks. The milling machine may also have a controller configured to determine the height based on the signal.

摘要： A control system is disclosed for use with a cold planer having a milling drum. The control system may have an obstacle detection sensor mountable to the cold planer at a location forward of the milling drum. The obstacle detection sensor may be configured to generate a first signal indicative of an object detected within a work surface. The control system may also have a locating device mountable to the cold planer and configured to generate a second signal indicative of a location of the cold planer at a time of first signal generation, and a controller in communication with the obstacle detection sensor and the locating device. The cold planer may be configured to generate an electronic map of a work area based on the first and second signals, and to selectively adjust operation of the cold planer based on the electronic map.

摘要： A milling machine may have a frame, a milling drum attached to the frame, and ground engaging tracks that support the frame and propel the milling machine in a forward or rearward direction. The milling machine may have a tank that stores hydraulic fluid. The milling machine may also have at least one actuator connecting the frame to the tracks. The actuator may adjust a height of the frame relative to a ground surface. A fluid conduit may connect the tank to the actuator. The milling machine may have a flow sensor in the fluid conduit. The flow sensor may determine a flow parameter associated with a flow of the hydraulic fluid into or out of the actuator. The milling machine may also have a controller that determines a height of the frame relative to the ground surface based on the flow parameter.

摘要： A milling machine may have a frame, a milling drum attached to the frame, and ground engaging tracks that support the frame and propel the milling machine in a forward or rearward direction. The milling machine may have height adjustable actuators connecting the frame to the tracks. Each actuator may have a cylinder attached to the frame, a piston slidably disposed within the cylinder, and a rod connected at a first end to the piston and connected to a track at a second end. The milling machine may have a tank storing hydraulic fluid and a fluid conduit connecting the tank to the cylinder. The milling machine may have a control valve selectively controlling a flow rate of the hydraulic fluid in the fluid conduit. The milling machine may also have a controller that determines a height of the frame relative to the ground surface based on the flow rate.
