Abstract
A device for detecting whether an engine brake condition exists includes a memory for storing the rotating speed of the engine corresponding to the degree of opening of the throttle valve, a detector for detecting the degree of opening of the throttle valve, a detector of the actual rotating speed of the engine, and a device for determining that the engine is an engine brake state when the actual speed of the engine corresponding to the actual degree of opening of the throttle valve exceeds the speed of the engine stored in the memory.
