Abstract
A method for redundantly controlling a speed of an internal combustion engine, in particular of a vehicle, which includes a redundantly actuatable actuator for adjusting the speed, the method includes the following steps: detecting a first actual speed and a second actual speed of the internal combustion engine, wherein the actual speeds are detected simultaneously and independently of one another; detecting a first actual position and a second actual position of the actuator, wherein the actual positions are detected simultaneously and independently of one another; determining a plausible actual speed and a plausible actual position in accordance with the detected actual speeds and/or the detected actual positions; and actuating the actuator for adjusting the speed in accordance with the plausible actual speed and the plausible actual position.
