Anticipatory control for hybrid vehicle propulsion system
A system and method are provided for placing a hybrid vehicle having a plurality of electric propulsion motors into an operating state in anticipation of a vehicle event, the method may include the steps of: monitoring roadway traffic and conditions surrounding a vehicle using one or more vehicle sensors and/or wireless communications; anticipating a vehicle propulsion operation change based on the monitored roadway traffic and conditions; in response to anticipating the vehicle propulsion operation change, obtaining a present propulsion operating state; and carrying out an anticipatory vehicle propulsion system transition before receiving a vehicle propulsion operation change request. The anticipatory vehicle propulsion system transition may include the steps of: calculating an intermediary propulsion operating state based on the present propulsion operating state and/or the monitored roadway traffic and conditions; and operating an internal combustion engine and a first electric propulsion motor such that the vehicle is placed in the intermediary propulsion operating state.
