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.

Abstract: With a tire pressure display device for a vehicle having several wheels, each monitored tire is provided with an electronic module (integrated pressure sensor with measuring and control electronics, said sensor being coupled to a high-frequency transmitter/receiver means). Away from the wheels, there is at least another high-frequency transmitter/receiver means coupled to a microprocessor (master means), that can exchange high-frequency radiograms with each module means in the interrogation-response mode. In addition, a remote control locking means (1) is present for activating a locking system on the vehicle. The triggering of a control command effectuated on the remote control locking means (1) for activating the locking system also activates the master means which then initializes the module means.
