Abstract
A method of substantially preventing road speed excursions while traversing a road grade event includes receiving, by a controller, vehicle operations data regarding operation of a vehicle and road grade data regarding an upcoming road grade of a path ahead of the vehicle. The method additionally includes determining, by the controller, an amount of braking power that substantially prevents the vehicle from exceeding a speed threshold regarding operation of the vehicle based on the road grade and vehicle operations data, and determining an amount of engine braking power based on a current transmission setting. The method further includes controlling, by the controller, a transmission setting in response to a determination that the amount of engine braking power is less than the amount of braking power.
