If a hazard is detected, a hazard message is transferred to a central server which can then communicate said hazard message to other vehicles. The hazard information can also be buffered by the server. ## Claims ### Claim at position 1 -17. (canceled) ### Claim 18 A hazard warning unit for a vehicle for detecting hazards and for warning about hazards, comprising: a sensing unit in the vehicle for sensing a measured value; an analysis unit for determining whether the sensed measured value corresponds to a hazard; and a communication unit for transferring information data about the hazard to a control center if the sensed measured value corresponds to the hazard. ### Claim 19 (depends on 18) The hazard warning unit as claimed in claim 18, wherein the communication unit is designed to transfer the measured value by way of GPRS, UMTS or WiMax. ### Claim 20 (depends on 18) The hazard warning unit as claimed in claim 18, wherein additional information data, which relate to a location at which the measured value was sensed, a time at which the measured value was sensed and the communication unit which transfers the information to the control center, are transferred to the control center together with the information data about the hazard. ### Claim 21 (depends on 18) The hazard warning unit as claimed in claim 18, wherein the communication unit is designed to receive warning data from the control center; and wherein the warning data are based on information data, received in the control center, of another communication unit. ### Claim 22 (depends on 21) The hazard warning unit as claimed in claim 21, wherein the communication unit is designed to call the warning data from the control center at defined times. ### Claim 23 (depends on 18) The hazard warning unit as claimed in claim 18 further comprising an encryption unit for encrypting the information data so that a uniquely defined assignment of the encrypted information data to the hazard warning unit is possible. ### Claim 24 (depends on 18) The hazard warning unit as claimed in claim 18, wherein the sensing unit has at least one sensor, selected from the group consisting of a GPS sensor, surroundings sensor, ESP sensor, camera, ABS sensor, traction control system sensor, driving state sensor, wheel speed sensors, steering wheel angle sensor and speed sensor. ### Claim 25 (depends on 18) The hazard warning unit as claimed in claim 18, wherein the control center is a traffic data control center as a service provider. ### Claim 26 (depends on 18) A hazard warning system for warning about hazards for a plurality of vehicles, the hazard warning system comprising: a hazard warning unit as claimed in claim 18; a control center for receiving information data from the hazard warning unit and for transferring warning data to the hazard warning unit; wherein the control center is also configured to produce the warning data on a basis of the measured values. ### Claim 27 (depends on 26) The hazard warning system as claimed in claim 26, wherein the control center is configured to transfer first warning data to a first hazard warning unit of a first vehicle, and to transfer second warning data to a second hazard warning unit of a second vehicle; and wherein the first warning data are different from the second warning data. ### Claim 28 (depends on 26) The hazard warning system as claimed in claim 26, wherein the control center is configured to receive information data from a plurality of hazard warning units of different vehicles and to generate the warning data on a basis of all the received measured values. ### Claim 29 (depends on 18) The use of a hazard warning unit as claimed in claim 18 in a vehicle. ### Claim 30 A method for warning a plurality of vehicles about a hazard, the method comprising the steps: sensing of a measured value by a sensing unit in a first vehicle; determining whether the sensed measured value corresponds to a hazard; and transferring information data about the hazard to a control center if the sensed measured value corresponds to the hazard. ### Claim 31 (depends on 30) The method as claimed in claim 30, further comprising the steps of: storing the following information: (i) a type of hazard, (ii) a location at which the measured value was sensed, (iii) a time at which the measured value was sensed, and (iv) an identification of a communication unit which transferred the information to the control center, in the control center; and generating warning data on a basis of the stored data. ### Claim 32 (depends on 30) The method as claimed in claim 30 further comprising the steps of: calling of warning data which are relevant for a second specific vehicle from the control center. ### Claim 33 A computer program product which induces a processor to carry out the following steps: sensing of a measured value by a sensing unit in a first vehicle; determining whether the sensed measured value corresponds to a hazard; and transferring information data about the hazard to a control center if the sensed measured value corresponds to the hazard. ### Claim 34 A computer-readable medium on which a computer program product is stored which induces a processor to carry out the following steps: sensing of a measured value by a sensing unit in a first vehicle; determining whether the sensed measured value corresponds to a hazard; and transferring information data about the hazard to a control center if the sensed measured value corresponds to the hazard.
