Publication number: 20240159551Abstract: Engine activation planning in a hybrid electric vehicle (HEV) is disclosed. Historical driving data of the HEV are analyzed to identify recurring driving scenarios and patterns specific to a driver of the HEV. Future driving scenarios are predicted based on the historical driving data. An engine activation policy is generated for the HEV. The engine activation policy optimizes battery charging and usage in response to the future driving scenarios. The engine activation policy is used to control activation of a gasoline engine in the HEV where a control decision is dynamically adjusted based on a comparison of real-time driving conditions with the future driving scenarios.Type: ApplicationFiled: January 16, 2024Publication date: May 16, 2024Inventors: Kyle Hollins Wray, David Ilstrup, Liam Pedersen, Richard Lui, Christopher Ostafew
