METHOD FOR CONTROLLING THE EMISSION POWER OF A TRANSMITTER SYSTEM INCORPORATED IN AN AUTOMOTIVE VEHICLE ELECTRONIC HOUSING, AND ELECTRONIC HOUSING REALIZED

摘要

The invention relates to a method for regulating the transmission power of a transmitter system (2, 5-7) incorporated in an electronic control unit (1) of a motor vehicle. According to the invention, there is provided a transmitter system (2, 5-7) comprising an amplification stage (2, 5) having an adjustable amplification gain. In addition, in a phase prior to the operation of the control unit (1), a compensation table is recorded for each type of transmitter system (2, 5-7) representative of the amplification gains to be applied to maintain a constant transmission power as a function of the value of external parameters representative of the environment of the transmitter system (2, 5-7), and for each electronic control unit (1), the value of the offset of the transmitter is memorized; amplification stage. Finally, when operating an electronic box (1), the amplification gain is adjusted on the one hand to compensate for the offset of the amplification stage (2, 5), and on the other hand. secondly depending on the environment by use of the compensation table.
