Detection method for detecting a speed sensing anomaly of an internal combustion engine and device for detecting the speed sensing anomaly

A method for detecting a speed sensing anomaly of an internal combustion engine, comprising the steps of:

• performing a sensor health check on a sensor of the internal combustion engine;
• detecting an engine speed deviation of the internal combustion engine;
• determining an actual torque of the internal combustion engine;
• performing a torque deviation check of the internal combustion engine based at least in part upon the actual torque and a torque associated with the engine speed deviation;
• identifying that the engine speed deviation refers to the speed sensing anomaly based on the sensor health check and the torque deviation check;
• and
• adjusting operation of the internal combustion engine to provide a protective action based at least in part upon identifying the speed sensing anomaly.
