Claim:
1. A control system for a vehicle compressor that is operable with a vehicle climate system comprising: a first control portion being configured to assess an actual temperature of a vehicle evaporator and a target temperature of the vehicle evaporator for generating a first compressor speed command signal in response to assessing the actual temperature and the target temperature; a second control portion including a pressure calibration value and being configured to receive a pressure reading of the climate system, to compare the pressure reading to the pressure calibration value, to generate a second compressor speed command signal if the pressure reading is greater than the pressure calibration value; a controller device including data corresponding to at least one compressor speed, the controller being configured to receive the first compressor speed command signal and the second compressor speed command signal and to transmit a control signal to the vehicle compressor for causing the vehicle compressor to operate at a commanded compressor speed based on the first compressor speed command signal, the second compressor speed command signal, and the data; and a speed limiter being configured to receive an apparent temperature reading for establishing a maximum compressor speed therefrom, the apparent temperature reading corresponding to the at least one compressor speed as identified in the data, wherein the apparent temperature includes at least an ambient temperature, humidity, and an interior temperature of a vehicle.
