Abstract
A method according to an exemplary aspect of the present disclosure includes, among other things, controlling an electrified vehicle by adjusting a deceleration rate based on a closing rate of the electrified vehicle to an oncoming object.
Claims22
A method, comprising:
- controlling an electrified vehicle by adjusting a deceleration rate based on a closing rate of the electrified vehicle to an oncoming object, wherein adjusting the deceleration rate includes modifying a negative portion of an accelerator pedal map.
A method, comprising:
- determining a desired deceleration rate of an electrified vehicle to an oncoming object;
- and
- modifying a negative torque demand associated with a predefined accelerator pedal position to achieve the desired deceleration rate to the oncoming object.
A method, comprising:
- determining a desired deceleration rate of an electrified vehicle to an oncoming object;
- and
- modifying a negative torque demand associated with a predefined accelerator pedal position to achieve the desired deceleration rate to the oncoming object, wherein the predefined accelerator pedal position is between a 0% pedal position and a pedal position that corresponds to zero torque demand or zero acceleration.
A vehicle system, comprising:
- an accelerator pedal;
- and
- a control module in communication with said accelerator pedal and configured to modify a deceleration rate of a vehicle by adjusting a negative torque demand associated with a predefined position of said accelerator pedal, wherein adjusting the negative torque demand includes raising or lowering said negative torque demand on an accelerator pedal map stored on said control module.
A method, comprising:
- during a lift pedal event of an electrified vehicle:
- raising a negative torque demand associated with a predefined accelerator pedal position on an accelerator pedal map in response to a first deceleration rate of the electrified vehicle relative to an oncoming object;
- and
- lowering the negative torque demand on the accelerator pedal map in response to a second, greater deceleration rate of the electrified vehicle relative to the oncoming object.
