1. 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.
