Abstract:
A vehicle air conditioning system includes a controller that initially controls operation of a compressor to switch between inactive and active states in response to detecting that an operating condition is equal to or surpasses a first operation threshold. The controller determines a first time delay occurring between initiating the switch from one of the inactive and active states to the other of the compressor, and an actual change in the operating condition. The controller subsequently defines a first limit that is offset from the first operation threshold such that the controller controls the operation of the compressor to subsequently switch from the one of inactive and active states to the other in response to detecting that the operating condition is equal to or surpasses the first limit.
