Abstract
A vehicle air compressor controller includes a compressor electronic control unit receiving a plurality of signals representing respective vehicle parameters. A variable torque transmitter is controlled by the compressor electronic control unit. The variable torque transmitter receives an engine speed from an engine of the vehicle and delivers a variable torque to a compressor of the vehicle for controlling a speed of the compressor. The variable torque is determined as a function of the engine speed and the vehicle parameters.
