An engine configured to drive a compressor of a vehicle air conditioning system is controlled based on a threshold condition. In at least one embodiment, a comfort-level selection is received, a threshold condition is determined based on the comfort-level, and a vehicle interior condition is detected. The engine is requested to run if the interior condition exceeds the threshold condition.

System and method for controlling a vehicle engine

Systems and methods to control an engine configured to drive a compressor of a vehicle air conditioning system having a desired temperature are provided. A time until a threshold is reached is determined based on an environment condition and a vehicle interior condition. A request for the engine to run is removed if the time is greater than a minimum time.

A method and system determines when a climate control system of a hybrid vehicle can be operated without the use of an A/C compressor. The method and system make this determination by determining whether the vehicle is at idle or is being driven and determining whether or not the A/C compressor is required to function to maintain air conditioning comfort in the vehicle. The A/C compressor couples to an engine of the vehicle when the engine is on in order to function. The method and system turn off the engine and thereby turn off the A/C compressor if the A/C compressor is not required to function and if the vehicle is at idle. The method and system turn off the A/C compressor without turning off the engine if the A/C compressor is not required to function and if the vehicle is being driven.
