Abstract
The invention relates to a tire pressure monitoring system with a wheel electronic to be installed in a pneumatic tire, comprising a battery as power source, a pressure sensor for measuring of tire pressure or pressure change, and a transmitter for transmitting pressure data, a receiver to be mounted either in or at the vehicle for receiving pressure data, a control unit for evaluating of pressure data, and a serial bus system via which, during operation, the control unit interrogates the receiver and receives subsequently pressure data from the receiver. In accordance with the invention it is provided that additionally to the serial bus system the receiver is also connected with the control unit via a data transfer line that is separate from the serial bus system, wherein the receiver notifies the control unit of critical pressure data via the data transfer line in an unrequested manner.
