1. A method for controlling a prime mover of a vehicle traveling on a surface including loose particles, the method comprising the steps of:
determining a vehicle speed with both an accelerometer and a location sensor, and wherein the values from both are filtered to provide a filtered vehicle speed;
determining a rotational speed of a vehicle wheel;
comparing the filtered vehicle speed to the rotational speed of the vehicle wheel and if the difference between the rotational speed of the vehicle wheel and the vehicle speed is greater than a threshold, then reducing the power provided by an electric motor to the wheel to maintain the difference between the rotational speed and the vehicle speed within the threshold.
