Abstract
A vehicle air conditioning control apparatus having an externally controlled type compressorand an externally controlled type cooling electric fanis disclosed in which a control map, for determining a duty ratio for a fan motorin terms of a compressor discharge pressure Pd, is determined based on the maximum efficiency point, for providing the maximum fuel consumption, that allows a total engine load torque, represented by a total sum of an engine load torque caused by the externally controlled type compressorand an engine load torque caused by a fan motor, to be a minimum torque, and a duty voltage to be applied to the fan motoris controlled using the compressor outlet pressure Pd and the control map which is determined.
