Abstract
A retarding system for an electric drive machine is provided. The retarding system includes an electrical retarding system and a hydraulic braking system. A single pedal controls both the electrical retarding system and the hydraulic braking system. The pedal includes a first range of travel that provides input to the electrical retarding system and a second range of travel that additionally controls the hydraulic braking system. The pedal further includes different levels of travel resistance in each of the two ranges of travel that correspond to providing inputs to the electrical retarding system and the hydraulic braking system.
