Abstract
A preemptive high-power engine start control system for a hybrid electric vehicle (HEV) having an electrified powertrain including an electric motor and an internal combustion engine. A controller is configured to perform operations including predict a vehicle travel route to a destination, determine one or more locations along the travel route where a high-power engine start will occur that requires propulsive power from both the electric motor and the internal combustion engine to satisfy a driver torque demand, and preemptively start the internal combustion engine prior to the vehicle reaching the one or more locations along the travel route where the high-power engine start will occur, to thereby facilitate preventing a torque delay during the high-power engine start.
Claims20
A preemptive high-power engine start control system for a hybrid electric vehicle (HEV) having an electrified powertrain including an electric motor and an internal combustion engine, the preemptive high-power engine start control system comprising:
- a controller having one or more processors and a non-transitory computer-readable storage medium having a plurality of instructions stored thereon, which, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
- predict a vehicle travel route to a destination;
- determine one or more locations along the travel route where a high-power engine start will occur that requires propulsive power from both the electric motor and the internal combustion engine to satisfy a driver torque demand;
- and
- preemptively start the internal combustion engine prior to the vehicle reaching the one or more locations along the travel route where the high-power engine start will occur, to thereby facilitate preventing a torque delay during the high-power engine start.
A preemptive high-power engine start control method for a hybrid electric vehicle (HEV) having an electrified powertrain including an electric motor and an internal combustion engine, the method comprising:
- predicting, by a controller having one or more processors, a vehicle travel route to a destination;
- determining, by the controller, one or more locations along the travel route where a high-power engine start will occur that requires propulsive power from both the electric motor and the internal combustion engine to satisfy a driver torque demand;
- and
- preemptively starting the internal combustion engine, by the controller, prior to the vehicle reaching the one or more locations along the travel route where the high-power engine start will occur, to thereby facilitate preventing a torque delay during the high-power engine start.
