Patent ID: 7230526

Claim:
A device for synchronizing a flasher frequency with a central flashing frequency, comprising: a central control device providing the central flashing frequency; a flasher device providing the flasher frequency being different from the central flashing frequency; a data transmission device which can be switched alternately into an active state and an idle state, information being transferable between said central control device and said flasher device in the active state and no information being transferable between said central control device and said flasher device in the idle state; said central control device determining, after a switchover of said data transmission device from the idle state to the active state, information relating to a phase of the flashing frequency from said flasher device for providing a correction signal for said flasher device, said correction signal being dependent on the phase of the flasher frequency and a phase of the central flashing frequency; and said flasher device modifying the phase of the flasher frequency and/or the flasher frequency itself in response to the correction signal for synchronizing the flasher frequency with the central flashing frequency.
