Tire-monitoring system and method therefor
First Claim
1. A method for monitoring a tire air pressure and/or at least one other tire-specific variable in tires of a vehicle, in particular of a trailer or semitrailer of a truck, having the following steps:
- detecting the tire air pressure and/or the at least one other tire-specific variable using a detection unit of a tire sensor in a tire and transmitting signals as a function of the detected variable by means of a transmitter of a control device of the tire sensor to a router in the vehicle;
receiving the signals transmitted by means of the transmitter by means of a receiver of the router and storing the variables transmitted with the signals in a memory of the router;
whereinthe router is supplied with electrical power for receiving the signals and storing the variables during driving operation of the vehicle via an electrical power terminal from an onboard electrical system of the vehicle;
characterized in thatthe router is supplied with electrical power from an energy storage of the router outside the driving operation of the vehicle when the onboard electrical system is turned off, wherein the energy storage is chargeable via the electrical power terminal when the onboard electrical system is turned on, andat least also when the onboard electrical system is turned off and the router is supplied with electrical power using its energy storage, a mobile communication device is at least indirectly coupled to an interface of the router for the wired or wireless query of the variables stored in the memory, which communication device connects itself via an Internet access to a database having router-specific data and initiates a bidirectional data connection with bidirectional data exchange between the database and the router either via a direct wireless connection between the router and the database or via an indirect connection via the mobile communication device.

Abstract
The invention relates to a tire-monitoring system for monitoring a tire air pressure and/or at least one other tire-specific quantity in tires of a vehicle; —comprising a plurality of tire sensors for positioning in the tires of the vehicle; —each tire sensor having at least one sensing device for sensing a tire-specific quantity and a control device that has at least one transmitter for transmitting signals in dependence on the sensed quantity and/or a quantity previously programmed in the control device; —and comprising a router for installing in the vehicle, which router comprises a receiver for receiving the signals of the plurality of tires sensors, a memory for storing the quantities of the tire sensors transmitted by means of the signals, and an interface for the wired or wireless retrieval of the stored quantities; —the router having an electrical power connection, by means of which the router can be connected to a vehicle electrical system for the supply of power to the router. The tire-monitoring system according to the invention is characterized in that the router has an energy store, which provides an electrical power supply when the vehicle electrical system is switched off and which can be charged by means of the electrical power connection.
