Abstract
A method for exhaust braking includes monitoring, by a controller of a vehicle, an engine speed of an internal combustion engine; comparing, by the controller, the engine speed with the a predetermined braking speed threshold to determine whether the engine speed is greater than the a predetermined braking speed threshold; and, in response to determining that the engine speed is greater than the a predetermined braking speed threshold, switching the vehicle to an exhaust braking mode.
