Abstract: A control system for determining the net power output of an engine associated with a work machine or other vehicle wherein parasitic loads encountered during engine operation are taken into account, the control system including an electronic controller coupled to the engine, at least one sensor coupled to the controller for inputting at least one signal representative of certain operating parameters associated with the engine, and at least one other sensor coupled to the controller for inputting at least one signal representative of the operation of any parasitic load encountered during engine operation, the controller being operable to determine the total output power of the engine and the power requirements associated with any parasitic load based upon the sensor signals.

Abstract: Apparatuses and methods for processing a signal in a moveable vehicle having an engine. A first combustion governor receives a first control signal and transmits a first governor signal operable to control an engine speed of the engine as a function of the first control signal. A second combustion governor receives the first control signal and to transmits a second governor signal operable to control an engine power production of the engine as a function of the first control signal. A first sensor determines a first characteristic of the vehicle transmits a first selecting signal as a function of the first characteristic. A governor-selecting device is coupled with the sensor to receive the first selecting signal.

Abstract: Apparatuses and methods for limiting torque of a motor on a vehicle. A torque limit determining device receives a weight signal indicative of an approximate weight of the vehicle. The torque limit determining device transmits a torque limit signal indicative of a torque limit for the motor as a function of the weight signal.
