Abstract: A method of substantially preventing road speed excursions while traversing a road grade includes: determining, by a controller, a predicted over speed for a vehicle during an upcoming downhill grade based on a difference between a predicted engine braking power of the vehicle and an amount of braking power that substantially prevents a speed of the vehicle from exceeding a speed threshold; and responsive to the determination, controlling, by the controller, one or more components of the vehicle to substantially prevent the vehicle from exceeding the speed threshold.

Abstract: A system, method, and apparatus includes management of coasting during operation of a vehicle having an engine that is selectively engageable to a driveline, a cruise control mode of operation, and a road speed governor mode of operation. A road speed governor mode of operation of the vehicle is active in response to a road speed governor operation condition being present wherein the driveline is engaged with the engine. When a coasting management condition is present, operation of the vehicle in the road speed governor mode is disabled, the driveline is disengaged from the engine, and the vehicle is operated in a coasting mode of operation. The coasting mode of operation can be canceled when a coasting mode of operation cancellation condition is present to operate the vehicle in a road speed governor mode of operation with the driveline re-engaged with the engine.

Abstract: Engine control modules as well as methods and systems implementable in a vehicle are disclosed, in which the engine control module includes a processing unit operative to control a target vehicle speed. The processing unit receives current status information and lookahead information regarding a route to be taken by the vehicle, performs a lookahead power requirement calculation based on the current status information and the lookahead information to determine an event, calculates a plurality of offsets with respect to an isochronous speed of the vehicle based on the determined event, and sets a target vehicle speed curve by applying the plurality of offsets to the isochroous speed.

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.
