Abstract
A compressor for a vehicle air conditioner includes a pressure sensor and a torque computing unit for computing the compressor torque. The compressor also has a communication unit that allows data communication with other devices based on vehicle data communication protocols. The torque computing unit and the communication unit are integral with the compressor. Therefore, it is possible to calculate the driving torque quickly, and an engine electronic control unit can control an engine such that the torque required for the compressor can be quickly generated.
