Abstract
A retarder system for a vehicular drive train is disclosed. The retarder system includes a compression brake being adapted to operate in multiple stages to slow the speed of the engine and a fluid retarder being adapted to operate in multiple stages to absorb power from the drive train. A controller regulates the operational stages of the compression brake and the fluid retarder so that the compression brake and the fluid retarder operate in combination to slow the speed of the vehicle.
