Abstract
A control system for protecting an internal combustion engine from overloading. The output of the internal combustion engine is adjusted with an output-determining signal according to an input signal which characterizes the desired output. According to the invention, a differential torque is calculated from the current motor torque and a maximum permissible motor torque. The differential torque in turn determines an authoritative second signal. A first signal that is determined from an input signal characterizing the desired output and the second signal are directed to a selector which selects the first or second signal as the signal that determines the output.
