Abstract
Methods and systems are provided for torque application during a deceleration event initiated via a shift lever direction change request. In one example, adjusting a deceleration torque towards a traction torque of a going to direction at a vehicle standstill based on an actual vehicle speed and an accelerator pedal position when the actual vehicle speed is below a threshold vehicle speed and a shift lever position is adjusted from a forward position to a reverse position.
Claims20
A method, comprising:
- adjusting a regenerative torque towards a traction torque at a vehicle standstill based on an actual vehicle speed and an accelerator pedal position when the actual vehicle speed is below a threshold vehicle speed and a shift lever position is adjusted from a forward position to a reverse position.
A system, comprising:
- a vehicle;
- a battery coupled to an electric machine;
- a shift lever coupled to a controller;
- and
- an accelerator pedal coupled to the controller;
- the controller comprising computer-readable instructions stored on memory thereof that when executed cause the controller to:
- apply torque as regenerative torque when regenerative braking is occurring and a vehicle speed is greater than or equal to a threshold speed;
- and
- transition a percentage of regenerative torque to traction torque when regenerative braking is occurring and the vehicle speed is less than the threshold speed.
A system for an electric vehicle, comprising:
- a battery coupled to an electric machine;
- a shift lever coupled to a controller;
- and
- an accelerator pedal coupled to the controller;
- wherein
- the controller comprises computer-readable instructions stored on memory thereof that when executed cause the controller to:
- apply torque as regenerative torque when regenerative braking is occurring and a vehicle speed is greater than or equal to a threshold speed;
- and
- transition a percentage of regenerative torque to traction torque when regenerative braking is occurring and the vehicle speed is less than the threshold speed, wherein the transition is based on a map plotting a vehicle speed, a torque command, and a position of the accelerator pedal.
