Method for controlling the transmission power of a transmitter system integrated in an electronic housing of a motor vehicle, and electronic housing thus obtained

摘要

Method for regulating the transmission power of a transmitter system (2, 5-7) incorporated in an electronic module (1) of an automobile. A transmitter system (2, 5-7) is produced which includes an amplification stage (2, 5) having an adjustable amplification gain. Furthermore, in a phase prior to the operation of the electronic module, a compensation table is stored for each type of transmitter system, which is representative of the amplification gains to be applied to maintain a constant transmission power according to the value of external parameters representative of the environment of the transmitter system, and the value of the offset of the amplification stage is stored for each electronic module. Finally, during the operation of an electronic module, the amplification gain is adjusted so as to compensate the offset of the amplification stage, and according to the environment by the use of the compensation table.
