摘要： A crawler track machine such as a cold planar milling machine may incorporate a steering system having multiple steering modes including coordinated steering modes as well as an improved crab mode. Orientations of front and rear pairs of crawler tracks may be managed via a linear actuator control system adapted to dynamically adjust lengths of front and rear tie rods. In one disclosed embodiment, the machine may include at least a coordinated four-track steering mode, an independent front track steering mode, and a crab mode. The crab mode may involve use of automated linear actuators on the tie rods to assure that all tracks remain substantially parallel to one another, and may involve the use of lookup tables to coordinate actuator movements in response to individual parallel track angle demands as a function of steering inputs.
