    • The invention relates to a vehicle unit in a vehicle, including at least one multimedia control unit and at least one safety control unit for controlling multimedia and safety functions, wherein the vehicle unit is provided as a switching unit between the multimedia control unit and the safety control unit, and wherein the switching unit processes the data received from the multimedia control unit and makes the data available to the safety control unit. The switching unit also transmits data received from the safety control unit to the multimedia control unit. Furthermore, the switching unit has a safety level which is higher than that of the multimedia control unit and lower than that the safety control unit.

    • A method for validating a vehicle-to-X message, in which the message is received by an antenna arrangement having a least two antenna elements connected with a communication device. An electromagnetic field strength of the message is recorded based on different reception characteristics with different power densities, wherein the message includes an absolute position of a transmitter, and an absolute position of a receiver determined on the basis of global satellite navigation or on a map comparison. A first relative position of the transmitter is calculated from the absolute positions of the receiver and the transmitter. A second relative position is calculated from the ratio of the power densities or read out from a reference diagram. If a comparison of the first and second relative positions reveals a large degree of correspondence, the message is validated, and if a large degree of deviation is detected, the message is rejected.
    • 一种用于验证车辆到X消息的方法,其中所述消息由具有与通信设备连接的至少两个天线元件的天线装置接收。 基于具有不同功率密度的不同接收特性来记录消息的电磁场强度,其中该消息包括发射机的绝对位置以及基于全球卫星导航确定的接收机的绝对位置或者在地图比较 。 根据接收机和发射机的绝对位置计算发射机的第一个相对位置。 从功率密度的比值或从参考图读出的第二个相对位置。 如果第一和第二相对位置的比较显示很大的对应关系,则消息被验证,并且如果检测到大的偏差,则该消息被拒绝。

    • An apparatus and a method for transmitting information in vehicle-to-vehicle communication based on IEEE802.11 standard WLAN, which involves both safety information based on the IEEE802.11p standard and non-safety-related information based on another IEEE802.11 standard being transmitted. The apparatus is equipped with a transmission and/or reception device which has a WLAN chipset. In order to achieve the vehicle-to-vehicle communication with a single piece of hardware, provision is made for the WLAN chipset to be able to be changed over by a control command between a first mode based on the IEEE802.11p standard and a second mode based on another IEEE802.11 standard and for the apparatus to have a control device which changes over the mode of the WLAN chipset using a control command.

    • A method for communicating between a first motor vehicle and at least one second motor vehicle, belonging to a mobile communication network including at least two motor vehicles. In a first step only one identifying piece of information is exchanged between the vehicles by each driver for forming a communication network by a radio communication unit via radio connection in order to initiate the internal communication of the vehicles present in a column formation, said piece of information being entered in a second step into a network communication unit of each vehicle, in order to join the communication network after acknowledgement by a network communication unit of at least one of the other vehicles belonging to the communication network. The identifying piece of information is an authentication, and the authentication takes place for each vehicle by a randomly generated password.
