Abstract
A method for preventing an unintentional start of a work-performing machine, wherein the work-performing machine includes an electric machine for propelling the work-performing machine, the method including checking whether there is a driving request from a driver of the work-performing machine and detecting information relating to an operating mode of the electric machine. The method further includes determining, based on the checking in relation to the driving request and the detected operating mode of the electric machine, whether the electric machine is in a safety-critical state and, if it is determined that the electric machine is in the safety-critical state, sending a signal to the electric machine to transition the electric machine to a state not suitable for propulsion.
