Abstract
Methods and systems for operating axles of a vehicle are provided. In one example, relationships between accelerator pedal position and driver demand torque may be adjusted as a function of a vehicle's geographical location. Further, a relationship between brake pedal position and requested braking amount may be adjusted as a function of a vehicle's geographical location.
Claims19
A method for operating a vehicle powertrain, comprising:
- adjusting a relationship between an accelerator pedal position and a powertrain torque request in response to a geographical position of a vehicle, where adjusting the relationship includes increasing a wheel torque with respect to the accelerator pedal position when the geographical position of the vehicle indicates that the vehicle is traveling off-road as compared to the wheel torque with respect to the accelerator pedal position when the geographical position of the vehicle indicates that the vehicle is traveling on-road.
A method for operating a vehicle powertrain, comprising:
- adjusting a relationship between an accelerator pedal position and a powertrain torque request in response to a geographical position of a vehicle;
- and
- adjusting a relationship between a brake pedal position and regenerative braking power in response to the geographical position of the vehicle.
A vehicle system, comprising:
- a first electric machine coupled to an axle;
- a global position detecting system;
- and
- a controller including executable instructions stored in non-transitory memory that cause the controller to adjust an amount of wheel torque that is provided to a vehicle as a function of accelerator pedal position in response to a vehicle being at a geographical location where wheel slip of the axle occurred at a time in the past.
