COMPUTER SYSTEM AND A METHOD FOR CONTROLLING AN ELECTRIC PROPULSION SYSTEM OF AN AUTONOMOUS WORKING MACHINE

A computer system and a method for control of an electric propulsion system of an autonomous working machine including a first axle and a second axle, the electric propulsion system including a first electric system configured to drive the first axle, including a first electric energy storage system, and a second electric system configured to drive the second axle, including a second electric energy storage system. The method includes determining a longitudinal gradient along an expected travelling path, determining charge levels of the first and second electric energy storage systems, respectively, and controlling the working machine to assume a first orientation or a second orientation to travel along the expected travelling path, wherein the orientation of the working machine is controlled in dependence on the determined longitudinal gradient and the determined charge levels.
