Abstract
In the transmission and air conditioning control system having an air conditioner provided with a compressor driven by an engine and an evaporator for cooling a passenger room, and a transmission connected between the engine and a wheel, an electronically control device controls the transmission ratio to a reference value to be decided by the operating condition of the vehicle and also to a final value, which is higher than the reference value, when a degree of cooling demand is greater than a predetermined value. As a result, the revolution of the engine is more increased so that the revolution of compressor may be more increased to improve the cool down performance.
