Abstract:
A transmission and air conditioning control system for a vehicle having an engine, a wheel and a passenger room comprising:an air conditioner provided with a refrigeration cycle comprising a compressor driven by the engine and an evaporator for cooling the passenger room, the air conditioner generating a command signal by which a degree of cooling demand is determined; a transmission connected between the engine and the wheel for changing an input revolution on a side of the engine to an output revolution on a side of the wheel at a transmission ratio of the input revolution to the output revolution that is variable according to operating conditions of the vehicle; and an electronically control device for controlling the transmission ratio to a reference value to be decided by the operating condition of the vehicle then prevailing and, upon receipt of the command signal, to a final value, which is higher than the reference value, when the degree of cooling demand decided is greater than a predetermined value, thereby to more increase the revolution of the engine than that based on the reference value so that a revolution of the compressor may be more increased; wherein:the electronically control device further controls the transmission ratio to the final value, which is lower than the reference value when the degree of cooling demand is smaller than a predetermined value, thereby to more reduce the revolution of the engine than that based on the reference value so that a revolution of the compressor may be more deduced.
