Abstract
The present invention relates to a method of controlling a network of electronic stations each suitable for generating at least one function, in particular for use on a motor vehicle. The method comprises the following steps: i) generating an activation signal in at least some of the stations when a previously inactive function is requested; ii) generating a deactivation signal when an associated 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 associated activation signal 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 when a counter reaches a zero count after being decremented.
