Abstract
A tire pressure display device for a vehicle having several wheels provides each monitored tire with an electronic module including, for example, an integrated pressure sensor with measuring and control electronics which are coupled to a high-frequency transmitter/receiver. Away from the wheels, there is at least another high-frequency transmitter/receiver that is coupled to a microprocessor that exchanges high-frequency radiograms with each wheel's electronic module in an interrogation-response mode. In addition, a remote control locking arrangement activates a locking system on the vehicle. The triggering of a control command effectuated on the remote control locking arrangement also activates the microprocessor, which then initializes the electronic module for each monitored tire.
