1. A method of controlling a network of electronic stations in a motor vehicle each suitable for generating at least one function, the method comprising the following steps:

  • i) generating an activation signal at at least one of the stations when a request is made for a previously inactive function;

    ii) generating a deactivation signal at the same station when a previously active function is to be deactivated;

    iii) detecting the generated activation and deactivation signals;

    iv) incrementing at least one counter by one step each time an activation signal associated with the counter is detected;

    v) decrementing the same counter by one step each time an associated deactivation signal is detected; and

    vi) generating a "go to sleep" signal whenever a counter reaches a zero count on being decremented.
