Abstract: In a method of operating a motor vehicle driven electrically, at least temporarily, on a roadway, the motor vehicle is moved fully autonomously by a control unit in response to a command for automatic operating mode. After a charging arm of the motor vehicle has been extended, a lateral control of the motor vehicle is executed to bring the extended charging arm into electric contact with a charging line arranged at or on the roadway. As a result, electric energy provided from the charging line to the charging arm is used for charging an energy accumulator of the motor vehicle and/or operating a drive device of the motor vehicle for moving the motor vehicle. A longitudinal control of the motor vehicle is executed to thereby maintain a predefined longitudinal speed of the motor vehicle until a distance of the motor vehicle reaches a predefined minimum distance to a leading vehicle.

Abstract: An attachment for a motor vehicle, is disclosed with at least one antenna having a conductor track for sending and/or receiving radio signals, wherein the attachment and the at least one conductor track of the antenna are designed as an injection moulded interconnect device.

Abstract: In a method for line-of-sight-independent data transmission in a car-to-car or a car-to-infrastructure communication system, electromagnetic radiation having encoded data is transmitted from a transmitter located in a first vehicle or in a traffic infrastructure object, and a reflector system is provided for at least partially reflecting the transmitted electromagnetic radiation, wherein the reflector system is arranged so that the transmitted electromagnetic radiation arrives at a receiver located in a second vehicle or in the traffic infrastructure object. The reflected electromagnetic radiation having the encoded data can then be received by the receiver even when line-of-sight communication between the vehicles is impossible.

Abstract: An antenna array for a motor vehicle has at least one seal which is composed of a nonconductive material and has an antenna which is mounted in the region of a sealing face of the seal and has the purpose of receiving radio signals. A convertible roof or sun roof or some other metallic vehicle part which is part of the antenna array can be positioned against the sealing face during the operation of the antenna and removed again. The antenna forms, with the metallic vehicle part which bears against the seal, the slot antenna which is effective between at least two metal faces. On the other hand, in the state in which no vehicle part bears against the seal, the antenna forms a flat electrical reception monopole which extends at a distance from a metal face which forms the antenna ground.
