Abstract: Methods and devices that use an engine load condition of a vehicle, for example, the vehicle's engine intake manifold or plenum vacuum, to promote the efficiency of the engine. The methods and devices are operable to control the compressor of the vehicle's air-conditioning system, enabling the compressor to be shut off when the vehicle is under relatively high loads. The methods and devices operate by sensing a parameter indicative of an engine load condition of the vehicle, determining a difference between a reading of the parameter and an average based on multiple readings of the parameter, and then engaging and disengaging the compressor clutch depending on whether the reading of the parameter is above or below the average of the parameter. The compressor clutch is engaged if the engine operates under a high load for a duration that is dependent on the average of the parameter.

Abstract: A method of constant airflow control for a ventilation system is disclosed. The method includes various controls to accomplish a substantially constant airflow rate over a significant change of the static pressure in a ventilation duct. One control is a constant I·RPM control, which is primarily used in a low static pressure range. Another control is a constant RPM control, which is primarily used in a high static pressure range. These controls requires neither a static pressure sensor nor an airflow rate sensor to accomplish substantially constant airflow rate while static pressure changes. This is because these controls use only intrinsic control variables which are electric current and rotational speed of the motor. Also, the method improves the accuracy of the control by correcting certain deviations that are caused by the motor's current-RPM characteristics. To compensate the deviation, the method adopts a test operation in a minimum static pressure condition.

Abstract: Power electronics for electric traction motors used to drive automotive vehicles are cooled in a closed system by spraying a dielectric liquid coolant directly onto inverter circuitry.

By utilizing the latent heat of evaporation of the dielectric coolant and increasing the rate recycling of the coolant as power output increases, temperature increases in the power electronics are controlled.
