ABSTRACT:
The minimum desired engine speed for engaging engine braking varies. The disclosed method includes determining a speed error by subtracting the desired engine speed from the actual engine speed, comparing the speed error to an error threshold, and generating a brake enable command if the speed error is greater than or equal to the error threshold.
