A method and system for generating an augmented machine view. The augmented machine view may include a dynamic virtual machine model representing an actual working machine, overlayed with camera footage from around the working machine. The dynamic virtual machine model may be synched in time with the camera footage. The system for generating the augmented machine view may include cameras mounted on the actual machine and machine sensors monitoring the position and movements of individual components of the machine.

Augmented machine user interface system

A machine comprises a frame, a plurality of ground engaging units, a plurality of moveable legs, and a hydraulic system. A first ground engaging unit and a second ground engaging unit connect a first leg and a second leg, respectively, with the frame. The hydraulic system controls heights of the plurality of moveable legs. The hydraulic system comprises a fluid circuit to control fluid between the first and second legs, a load holding valve to control fluid flow into the fluid circuit, and first and second relief valves to control flow of fluid between the first and second legs in opposite directions. A method for controlling slope of a construction machine comprises activating a relief valve connecting right and left lifting cylinders to control flow of hydraulic fluid between the lifting cylinders to control retraction of one of the lifting cylinders from retracting.

A milling machine may have a frame extending along a longitudinal axis and a milling drum attached to the frame. The milling machine may have ground engaging tracks that support the frame, and height-adjustable leg columns connecting the frame to the tracks. The milling machine may also have an engine for rotating the milling drum and propelling the ground engaging tracks. The milling machine may have a slope sensor to measure a roll angle of the frame, a speed sensor to measure a ground speed, and a configuration sensor to measure a machine configuration parameter. The milling machine may also have an alarm device and a controller. The controller may determine a threshold roll angle based on the machine configuration parameter, compare the roll angle with the threshold roll angle, and activate the alarm device when the roll angle is greater than or equal to the threshold roll angle.
