METHOD FOR ESTIMATING THE POWER CONSUMPTION OF A MOTOR VEHICLE AIR-CONDITIONING SYSTEM AND CONTROLLING AN INTERNAL COMBUSTION ENGINE

摘要

A method for estimating the power consumption of an air-conditioning system on board a motor vehicle (1) is disclosed. The system includes a compressor (3), a condenser (4) combined with a first motor-driven fan (5), an evaporator (8) combined with a second motor-driven fan (9), and an air conditioning computer (11). The method comprises the steps of acquiring data values related to the operation of said air-conditioning system, and computing said power consumption, or reading same from a table, on the basis of said values. Said data includes the high output pressure of the compressor (3), the rotation speed of the compressor (3), and the air flow through the evaporator (8).
