Abstract
An air conditioning control system for an automotive vehicle, comprises a compressor controllable in capacity in response to an external control signal, an evaporator connected to the compressor, a sensor for sensing a temperature of the evaporator, an arithmetic control section for calculating a value of the control signal based upon an output from the sensor, and an output section for supplying the control signal having a value calculated by the arithmetic control section to the compressor. The arithmetic control section carries out first mode control in which it calculates the value of the control signal so that the temperature of the evaporator is held at a predetermined value. The arithmetic control section carries out, in addition to the first mode control, second mode control in which, if a predetermined condition is satisfied, it calculates the value of the control signal so that the capacity of the compressor is brought to the maximum value, for a limited period of time after the compressor is started.
