    摘要： The described systems and methods relate to employing an Electric Air Charging System (EACS) to maintain a hybrid commercial vehicle (or the like) battery within a desired range of charge. The innovation facilitates reducing battery charge when the state of charge is too high, such as by adjusting air compressor cut-in and cut-out pressure thresholds to cause the air compressor to compress air for the brake system when there is excess charge in the battery, as well as triggering a brake regeneration protocol and/or other charge regeneration protocol(s) to restore charge to the battery when the state of charge of the battery is too low.

    摘要： 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.

    摘要： When controlling an air compressor (13) for a pneumatic braking system on a large hybrid commercial vehicle (e.g., a bus, a package delivery truck, etc.), PID control of an air compressor motor (12) is employed during normal system operation such as when the motor shaft is spinning, and state machine control is employed during startup or upon a system disturbance such as a shaft seizure or stall. In this manner, stalling events that occurs due to PID control inability to correct for unexpected disturbances are mitigated by employing state machine control.

    摘要： Controlling air compressors based on a temperature of air compressed by the air compressor. A temperature of air compressed by the air compressor is sensed. The sensed compressed air temperature is compared with a predetermined threshold temperature. The air compressor is deactivated when the sensed temperature exceeds the threshold temperature. The threshold temperature may be selected to inhibit carbon formation caused by oil thermal breakdown.
