A method and apparatus including a control device for controlling an automotive air conditioning system is disclosed which includes a temperature detecting sensor disposed in proximity to the air conditioning system, an acceleration detecting device for detecting acceleration of an automobile and a control unit. The control unit compares the detected air temperature with predetermined temperatures and controls the capacity of the compressor in accordance with the compared results and the acceleration condition of the automobile. Therefore, the temperature in a compartment of this automobile can be maintained at a comfortable level and the power load imposed on the automobile engine can be reduced by operating the compressor at a reduced capacity.

A control device for controlling the operating capacity of a compressor in an automobile air conditioning system comprising temperature detecting means for detecting air temperature, acceleration detecting means for detecting an accelerating condition of the automobile, and control means for control

A control device for controlling the operating capacity of a compressor in an automobile air conditioning system comprising temperature detecting means for detecting air temperature, acceleration detecting means for detecting an accelerating condition of the automobile, and control means for controlling a variable displacement mechanism of said compressor, said control device including: first comparison means for comparing a first predetermined temperature with a detected air temperature and providing a first control signal when the air temperature is higher than said first predetermined temperature, wherein the operation of said compressor is terminated in the absence of said first control signal, second comparison means for comparing a second predetermined temperature with said detected air temperature in response to the comparison by the first comparison means and the presence of said first control signal, said second comparison means providing a second control signal when said detected air temperature is higher than said second predetermined temperature, wherein said variable displacement mechanism causes said compressor to operate at a reduced capacity in the absence of said second control signal, means responsive to the detected acceleration condition of the automobile and the presence of said second control signal for causing said variable displacement mechanism to cause said compressor to operate at a reduced capacity upon the occurrence of a first acceleration condition and at full capacity upon the occurrence of a second acceleration condition.
