Abstract
Methods and systems for operating an electric vehicle in neutral are provided herein. The vehicle system, in one example, includes an electric machine rotationally coupled to a driveline and an input device with a neutral position. The system further includes a control unit with instructions that when executed, in response to movement of the input device into the neutral position, cause the control unit to operate the electric machine to apply a regenerative torque to a driveline and generate electrical energy.
Claims20
A vehicle system, comprising:
- an electric machine rotationally coupled to a driveline;
- an input device with a neutral position;
- a control unit including instructions that when executed, in response to movement of the input device into the neutral position, cause the control unit to:
- operate the electric machine to apply a regenerative torque to the driveline and generate electrical energy.
A method for operation of a vehicle system, comprising:
- while an input device of the vehicle system is in a neutral position, operating a control unit to apply a regenerative torque to a driveline via operation of an electric machine, wherein an amount of regenerative torque is based on an accelerator pedal position.
A system for a vehicle;
- comprising
- an electric machine rotationally coupled to a driveline;
- an input device comprising a forward position and a neutral position;
- a control unit including instructions that when executed cause the control unit to:
- operate the electric machine to apply a regenerative torque to the driveline and generate electrical energy based on a combination of a vehicle speed and a position of an accelerator pedal in response to movement of the input device into the neutral position.
