[6] Method (100) according to one of claims 1 to 5, further comprising: - Determining a relative position of the transmitting device (10) with respect to the at least one receiving device (20a-d) using a short-range localization, in particular if the hazard warning (GW) does not comprise first localization information and second localization information. [7] Method (100) according to one of claims 1 to 6, wherein performing at least one warning action by the at least one receiver device (20a-d) in response to the hazard warning (GW) received from the transmitter device (10) comprises: - Outputting at least one optical and / or acoustic and / or haptic warning message by controlling at least one output device; and / or - forwarding the hazard warning (GW) or information relating to the hazard warning (GW) to at least one central unit (20d); and / or - Instructing at least one technical system to perform at least one action. [8] Method (100) according to one of claims 1 to 7, wherein the communication protocol of the short-range radio technology corresponds to the Bluetooth standard, in particular the Bluetooth Low Energy standard. [9] Hazard warning system comprising: - a transmitting device (10); and - at least one receiver device (20a-d), - wherein the transmitting device (10) is configured to transmit a hazard warning (GW) to the at least one receiving device (20a-d) in an environment of the transmitting device (10), wherein the transmission of the hazard warning (GW) is carried out using a communication protocol of a short-range radio technology, and wherein the hazard warning (GW) relates to a hazard in an area of the transmitting device (10) and / or the at least one receiving device (20a-d), - wherein the at least one receiving device (20a-d) is configured to perform an authentication of the transmitting device (10), and - wherein the at least one receiving device (20a-d) is configured to perform at least one warning action in response to the hazard warning (GW) received from the transmitting device (10) if a positive authentication of the transmitting device (10) has taken place. [10] Vehicle, in particular motor vehicle, comprising a transmitting device (10) for hazard warnings, - wherein the transmitting device (10) is configured to transmit a hazard warning (GW) to at least one receiving device (20a-d) in an environment of the vehicle, - whereby the transmission of the hazard warning (GW) is carried out using a communication protocol of a short-range radio technology, - wherein the hazard warning (GW) relates to a hazard in an area of the vehicle and / or the at least one receiver device (20a-d), - wherein the hazard warning (GW) is configured so that the transmitting device (10) can be authenticated by the at least one receiving device (20a-d), and - wherein the hazard warning (GW) is configured so that at least one warning action can be carried out by the at least one receiving device (20a-d) in response to the hazard warning (GW) received from the transmitting device (10) if a positive authentication of the transmitting device (10) takes place. [11] Vehicle, in particular motor vehicle, comprising a receiver device for hazard warnings, - wherein the receiver device is configured to receive a hazard warning (GW) from a transmitter device in an environment of the vehicle, - whereby the transmission of the hazard warning (GW) is carried out using a communication protocol of a short-range radio technology, - where the hazard warning (GW) concerns a hazard in an area of the transmitting device and / or the vehicle, - wherein the hazard warning (GW) is configured so that the transmitting device can be authenticated by the receiving device, and - wherein the hazard warning (GW) is configured so that at least one warning action can be carried out by the vehicle in response to the hazard warning (GW) received from the transmitting device if a positive authentication of the transmitting device takes place.
