Abstract
Methods and systems are provided for a hybrid electric vehicle. In one example, a method may include delaying an electric-only operation of the hybrid vehicle in response to a powertrain temperature being less than a threshold powertrain temperature and an electric-only range being less than a distance between a current location and a recharging location. The electric-only operation may be initiated in response to one or more of the powertrain temperature exceeding the threshold powertrain temperature and the electric-only range being equal to the distance.
Claims20
A system for a hybrid vehicle comprising:
- an engine and an electric motor;
- and
- a controller with computer-readable instructions stored on non-transitory memory thereof that when executed enable the controller to:
- operate with engine propulsion and monitoring an increasing electric-only operation range determination increasing toward remaining trip distance as a powertrain temperature increases while state of charge is maintained and delaying electric-only operation, the electric-only operation range determined based on powertrain temperature, and then switch from engine propulsion to electric motor propulsion in response to the remaining trip distance at or greater than the determined electric-only operation range.
A method for a hybrid vehicle comprising an engine and an electric motor, comprising:
- delaying an electric-only positive traction operation of a trip from a starting location to a recharging location until only after a remaining trip distance is equal to a determined electric-only range only when autonomous driving is requested, the electric-only operation initiated by deactivating the engine and activating the electric motor independently of vehicle operator input outside of accelerator and brake pedal actuation, where the determined electric-only range is determined based on powertrain temperature and increases as temperature increases while state of charge is maintained.
A system comprising:
- a hybrid-electric vehicle comprising an engine and an electric motor coupled to a battery;
- and
- a controller with computer-readable instructions stored on non-transitory memory thereof that when executed enable the controller to:
- request input from a vehicle operator regarding a total trip distance, where the total trip distance is measured from a starting location to a recharging location;
- delay an electric-only operation of the hybrid-electric vehicle in response to the total trip distance being greater than an electric-only range, the electric-only range determined based on powertrain temperature and increasing as temperature increases while state of charge is maintained;
- and
- activate the electric-only operation in response to the determined electric-only range being equal to a remaining trip distance, where the remaining trip distance is measured from a current location to the recharging location.
