Abstract

The invention relates to a method for monitoring air pressure in vehicle tires using wheel electronics, which comprise a pressure sensor for measuring the air pressure present in the tire, a transmitter for transmitting pressure information, and a receiver for receiving interrogation signals, wherein a transmission activity of the wheel electronics is triggered by the reception of an interrogation signal, which is transmitted as a pulse train comprising a command section that encodes a transmission instruction for the wheel electronics. According to the invention, the pulse train comprises an adjustment section having several pulses before the command section.
