ABSTRACT:
In a vehicle, such as a construction vehicle, which has a payload of variable but significant weight with respect to the empty weight of the vehicle, a sensor senses the weight of the payload and transmits a signal representative thereof to a processor. The processor modulates clutch transmission fluid pressure as a function of the payload, permitting more uniform operating characteristics. The sensor can be a hydraulic fluid pressure sensor installed in a hydraulic cylinder used to lift a payload bucket arm.
