Tire pressure display device
First Claim
1. A tire pressure display device for a vehicle having several wheels, each of which is fitted with a pneumatic tire, whereby each monitored tire is provided with an electronic module having at least one integrated pressure sensor with measuring and control electronics, said sensor being coupled to a high-frequency transmitter/receiver means (in short:
- module means);
away from the wheels, there is at least another high-frequency transmitter/receiver means coupled to a microprocessor (in short;
master means), which is configured for bi-directional high-frequency signal-data communication with each module means in the interrogation-response mode;
the tire pressure status of each monitored tire is displayed on one or more display element(s) of a display device that is actuated by display signals that have been generated by the microprocessor, characterized in that additionally, a remote control locking means for activating a locking system on the vehicle is present;
an actuation of this remote control locking means for the wireless transmission of a control command to the vehicle for the activation of a locking system in the vehicle also activates the master means which then carries out an interrogation of the module means according to such a sequence control that ensures that at no point in time do response signals from several module means reach the master means at the same time or overlapping in time; and
the display element(s) of the tire pressure status display device is/are situated on the remote control locking means or on an add-on device that is located on or adjacent to the remote control locking means.

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.

18. A method for the operation of a tire pressure display device intended for a vehicle with several pneumatic tires, having:
-
on each monitored tire, an electronic module having at least one integrated pressure sensor with measuring and control electronics, said sensor being coupled to a high-frequency transmitter/receiver means (in short;
module means);
away from the wheels, at least another high-frequency transmitter/receiver means coupled to a microprocessor (in short;
master means), which is configured for bi-directional high-frequency signal-data communication with each module means in the interrogation-response mode;
a display device with one or more display element(s) for displaying the tire pressure status of each monitored tire;
a remote control locking means that has a pushbutton to trigger a control command that activates a locking system of a vehicle;
characterized in that the actuation of the pushbutton of the remote control locking means also activates the master means which then initializes the module means;
the initialization of the module means takes place according to a sequence control that ensures that at no point in time do response signals from several module means reach the master means at the same time or overlapping in time; and
the tire pressure status thus obtained for each monitored tire is displayed by means of display elements that are situated on the remote control locking means or on an add-on device that is located on or adjacent to the remote control locking means. - View Dependent Claims (19, 20, 21, 22)
