Description

technical field [0001] The present invention relates to the technical field of vehicle control, in particular to a differential control system, method and computer-readable storage medium of a hot metal vehicle. Background technique [0002] The working environment of hot metal trucks is generally complex and harsh. Long-term transportation of 80 to 380T hot metal tanks in an environment of high temperature and severe metal dust pollution requires very high requirements for the stability and control accuracy of the hot metal truck drive system. The hydraulic suspension of the molten iron vehicle needs to be partially adjusted before the molten iron tank is transported and after the molten iron tank is loaded. Firstly, to ensure that the platform of the molten iron vehicle is in a horizontal position, and secondly, to ensure that the driving wheel and driven wheel of the molten iron vehicle are in full contact with the ground. To ensure that the driving tires are completely a...
