1. A method for controlling the speed of a vehicle comprising:

  • sensing, via an electronic controller and a sensor, a position of an operator input;

    determining, via the controller and the sensor, whether the position of the operator input is above or below a first threshold;

    engaging, via the controller and the sensor, a retarder only upon the position of the operator input falling below a first threshold;

    modifying, via the controller and the sensor, a retarding force exerted by the retarder based on the position of the operator input while the retarder is engaged and the position of the operator input is below a second threshold above the first threshold; and

    disengaging, via the controller and the sensor, the retarder upon the position of the operator input rising above the second threshold.
