Coasting management control of a vehicle with a road speed governor

Last updated:

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.
