Abstract: A method of controlling a hybrid propulsion system of a vehicle, the hybrid propulsion system including an internal combustion engine and an alternate powertrain torque source capable of propelling the vehicle while the engine is turned off, the method comprising of detecting congestion by receiving and analyzing data that is external to the vehicle, and controlling a transition of the hybrid propulsion system between a first propulsion mode and a second propulsion mode based on said detecting of congestion.

Abstract: A vehicle engine is controlled based on a distance between the vehicle and an object other than the vehicle. In at least one embodiment, a system for controlling an engine in a vehicle is provided. The system includes an environment sensor arrangement configured to sense a distance between the vehicle and an object other than the vehicle and an operating sensor arrangement configured to sense an operating state of the vehicle. The system also includes a control module configured to determine whether to start or stop the engine based on the distance and the operating state.
