Abstract
The present invention provides improved, real time sensing of pressure supplied to the hydraulic operator of a clutch for a motor vehicle driveline power take off. A proportional sensor in the hydraulic line to the power take off clutch actuator provides a data signal in real time of the actual pressure applied to the clutch actuator. This signal is provided to the power take off control module (PCM) and/or to the transmission control module (TCM). The power take off control module, having instantaneous data regarding the pressure applied to the hydraulic operator achieves two important operating functions: monitoring and feedback.
