摘要:
A system and method for a navigation system for a complex menu-controlled multifunctional vehicle control system. The system has a navigation unit and a man-machine interface which are arranged separately at different locations in the vehicle. Between the two units there is a communication link which is of bidirectional design.

According to one exemplary embodiment of the invention, a vehicle antenna apparatus is provided on a vehicle in such a way that this results in the antenna having a horizontal main beam direction. A first reflection apparatus above the conductive roof of the vehicle, with an exciter between these two elements, causes the reflections to be doubled, thus causing the main beam direction to be lowered from a vertical to a horizontal direction.

摘要:
The invention relates to a method and a correspondingly arranged communication device for channel estimation in vehicle-to-environment communication, wherein a model of the environment influencing the vehicle-to-environment communication is produced from parameters of a vehicle-to-environment communication and the quality of the model for the environment is ascertained by the convergence of the parameters used in the model. The course of the convergence of the parameters in the model is monitored and conclusions are drawn with regard to the environment from the course of the convergence of the parameters.

摘要:
A device for testing a safety and/or driver assistance system of a first vehicle with the participation of at least one second vehicle in the region of a fixedly predefined roadway section in particular in the region of an intersection, wherein the first vehicle and the at least one second vehicle comprise in each case at least one transmitter and/or at least one receiver for the C2X communication in connection with the safety and/or driver assistance system. In order to prevent or to keep to a minimum damages to vehicles and/or injury to persons, the second vehicle is represented by a dummy device that moves in the region of the roadway section, the dummy device having the largest portion of its volume and/or its mass outside the movement of the first vehicle.
摘要:
A dummy device for testing a driver assistance system of a vehicle traveling on a roadway. The dummy device travels above the roadway, and includes a transceiver and a processor to test the driver assistance system of the vehicle by simulating a driver assistance system of another vehicle.
摘要:
A vehicle key for radio communication with a vehicle. The vehicle key has a radio transmitter for transmitting radio signals to the vehicle. The vehicle key has a radio receiver and/or audio receiver to be able to locate the vehicle within close range. A bidirectional communication with a transceiver of the vehicle is set up by the radio receiver and/or the audio receiver and the radio transmitter. Furthermore, a corresponding method for locating the vehicle by using the vehicle key is described.
