Abstract
A vehicle includes a powertrain and a controller. The controller, responsive to a parameter indicative of a grade on which the vehicle is travelling having a value greater than a threshold, and a given accelerator pedal input, commands the powertrain to produce an amount of drive torque for the vehicle that is based on the value.
Claims15
A vehicle comprising:
- a powertrain;
- and
- a controller programmed to,
- responsive to a speed of the vehicle being less than a speed threshold, a difference between an acceleration of the vehicle derived from a rotational speed sensor of the powertrain and an acceleration of the vehicle derived from an accelerometer being less than a difference threshold, and a given accelerator pedal input, command the powertrain to produce a first amount of drive torque for the vehicle that is not based on the difference, and
- responsive to the speed being less than the speed threshold, the difference being greater than the difference threshold, and the given accelerator pedal input, command the powertrain to produce a second amount of drive torque for the vehicle that is based on the difference such that the first amount is less than the second amount when the vehicle is travelling uphill and the first amount is greater than the second amount when the vehicle is travelling downhill.

A method for controlling a vehicle including a powertrain, comprising:
- by a controller, responsive to a speed of the vehicle being less than a speed threshold and a given accelerator pedal input, commanding the powertrain to produce a first amount of drive torque for the vehicle based on a difference between an acceleration of the vehicle derived from a rotational speed sensor of the powertrain and an acceleration of the vehicle derived from an accelerometer.
