Abstract
A method for stopping undesired continuation in a current direction of travel of a work machine, wherein the work machine has an electrical machine for propulsion of the work machine, the method including detecting a desired direction of travel of a driver of the work machine. The method further includes detecting a state variable of the work machine that correlates with an actual direction of travel of the work machine determining, on the basis of the detected desired direction of travel and the detected state variable, whether the electrical machine is in a safety-critical state, and, if it has been determined that the electrical machine is in the safety-critical state, sending a signal to the electrical machine to convert the electrical machine into a state not suitable for propulsion.
