ABSTRACT:
An automotive air conditioner shutoff system that disengages the air conditioner compressor when the value of a parameter indicative of the vehicle's performance is below a certain variable threshold. The threshold varies as a continuous function of accelerator pedal position or throttle valve position. In addition, the air conditioner fan may also be controlled by the air conditioner shutoff system of the present invention. Further, the air conditioner shutoff system of the present invention may act to shut off the air conditioner when the engine is overheated or when the engine has not yet warmed up or stabilized. Additionally, the vehicle operator can modify the value of the variable threshold for the performance indicating parameter, and entirely override the air conditioning shutoff system.
