Abstract
A motor controller unit facilitates modifying pressure thresholds and motor operation mode for an air compressor in a hybrid commercial vehicle as a function of vehicle air demand and comprises a processor configured to execute computer-executable instructions comprising monitoring vehicle air system pressure, calculating air demand generated by the vehicle air system, and determining that the vehicle air system air demand is greater than a predetermined air demand threshold. A cut-out pressure threshold for the compressor motor is increased and the air compressor motor is switched from an on/off mode to a continuous run mode wherein pressure is maintained in the air system to be between a cut-in pressure threshold and the increased cut-out pressure threshold. The compressor motor operates in the continuous run mode until air demand falls below the predetermined air demand threshold.
