  • Method of torque prediction for automotive air conditioning compressor
    Patent number: 9987905
    Abstract: The torque of a vehicular air-conditioning compressor is predicted by the steps of starting a vehicle air-conditioning system having an engine and engine control module for controlling multiple vehicle functions, calculating a steady state torque value using an rpm value from the engine, calculating an engine RPM transient torque value using the rpm value from the engine, calculating a electronic control valve current transient torque value using a current value applied to an electronic control valve, selecting a final torque value from a group consisting of the steady state torque value, the engine RPM transient torque value, and the electronic control valve transient torque value, and providing a final torque value to the vehicle engine control module to control a predetermined vehicle function.

  • Electronic control valve having an integral non-contact noise mitigation device
    Patent number: 9309987
    Abstract: An electronic control valve having a valve stationary portion defining a substantially central bore extending along an axis of the valve, and a valve train including a movable member of the valve. The valve train moveable member is disposed in the central bore, and the valve train is adapted for reciprocal movement along the axis. A mass is engaged is with the valve train and adapted for reciprocal movement along the axis. A biasing means is disposed between the valve train and the mass. Reciprocal movements of the mass along the axis induced by forces exerted along the axis by the valve train are transmitted through the biasing means, whereby reciprocal movement of the valve train along the axis is dynamically reduced by the mass.

  • METHOD OF TORQUE PREDICTION FOR AUTOMOTIVE AIR CONDITIONING COMPRESSOR
    Publication number: 20140180607
    Abstract: The torque of a vehicular air-conditioning compressor is predicted by the steps of starting a vehicle air-conditioning system having an engine and engine control module for controlling multiple vehicle functions, calculating a steady state torque value using an rpm value from the engine, calculating an engine RPM transient torque value using the rpm value from the engine, calculating a electronic control valve current transient torque value using a current value applied to an electronic control valve, selecting a final torque value from a group consisting of the steady state torque value, the engine RPM transient torque value, and the electronic control valve transient torque value, and providing a final torque value to the vehicle engine control module to control a predetermined vehicle function.
