METHOD FOR DETERMINING THE POWER OF AN ELECTRIC MOTOR OF A HYBRID COMPRESSOR

摘要

The invention relates to a method for determining the power (Welec) of an electric motor (20) for driving a hybrid compressor (10; 10′) of an air-conditioning circuit of a motor vehicle having a heat engine during phases in which the drive of the hybrid compressor by the heat engine is interrupted. According to the invention, said method includes steps that consist of: defining a maximum temperature (Tmax) measured at a point (13) of said air-conditioning circuit; setting a reference duration (tref) for the phases during which the drive of the hybrid compressor (10; 10′) by the heat engine is interrupted; determining the power (Welec) of the electric motor (20) such that, at the end of said reference duration (tref), the temperature measured at said point (13) of the air-conditioning circuit is at most equal to said maximum temperature (Tmax). The invention can be used for air-conditioning motor vehicles having a heat engine and provided with an automatic stopping and restarting system.
