Data transfer method for lighting headlight of motor vehicle, involves generating carrier signal on supply line in master module so that slave module and master module utilize generated signal

摘要

The method involves transmitting a carrier signal (48) on an electric line (10), modulating the signal at a slave module, and demodulating the signal at a master module. The carrier signal is generated on the supply line in the master module so that the slave module utilizes the signal generated by the master module while the master module itself utilizes the same signal. An independent claim is also included for a device for implementing a data transfer method.
