摘要:
A method for transmitting travel route information to a person present outside of a motor vehicle, and to a system for transmitting such information. The method for transmitting travel route information to a person present outside of a motor vehicle provides that a navigation system present in the motor vehicle wirelessly transmits a data stream including the information to be transmitted directly or indirectly to a display device carried by the person. The information to be transmitted can be perceived by the person by the display device.
摘要:
A method and system for ascertaining at least one traffic-related local information item for a vehicle includes a reception device in a radio system to receive sent data from a radio system in at least one other vehicle in the vicinity of the one vehicle as defined by the reception range of the reception device. The reception device is configured for the vehicle-internal capture and evaluation of data for at least one operating variable from the one vehicle. The traffic-related local information item is ascertained from the received data from the other vehicle.
摘要:
A method for checking communication messages in vehicle-to-environment communication, a communication message being received and evaluated, and to a receiver suitable for carrying out the method. In order to check a communication message, a feature obtained from the content of the communication message is compared to a feature that corresponds to said feature, the corresponding feature being obtained by a sensory system that is independent of the vehicle-to-environment communication.
摘要:
A method for operating a communication system in wireless vehicle-to-environment communication includes: transmitting, using the communication system, different information as signals on various radio channels in accordance with its content, the communication system having at least two reception paths each having at least one separate antenna and an associated separate receiver for receiving the transmitted signals; and changing over the communication system between two modes of operation when a changeover criterion is satisfied, such that the at least two reception paths receive signals on a different radio channel in a first mode of operation and receive signals on the same radio channel in a second mode of operation.
摘要:
Disclosed is a method and a circuit configuration as well as a navigation system are disclosed, wherein the extraction and transmission of signals running on a line bus (1, 2) is carried out without having to sever the bus cable. Furthermore, a sensor (4) is disclosed, which outputs sensor signals reproducing the line signals and wherein the output sensor signals are amplified by a signal processing unit (11) and transformed into a defined digital signal shape (22). The filtered signals are then transmitted to a display device (14) or another device via an additional bus in wireless manner or by way of a line. The invention further relates to a tapping device for the wireless tapping of CAN data from a CAN line by the electromagnetic field, without having to sever the CAN lines, having a pivotable top shaped part (32), which can be pressed against a bottom part (35) by way of a pivot mechanism (41) for the purpose of accommodating CAN cables, and guide grooves (31 for accommodating the CAN cables (CAN1, CAN2), with conductor loops, in the closed position of the pivot mechanism, being closed around the CAN cables which are connectable to a signal processing electronics.
摘要:
A method and a device for triggering an emergency call in a vehicle equipped with an airbag. The device can be retrofitted in a vehicle equipped with an airbag to provide an emergency system which, in the event of an airbag being triggered, sends an emergency call (Ecall) to a suitable emergency call center in order to initiate auxiliary measures as may be necessary.
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:
Channel estimation for wireless communication between a motor vehicle and another communication subscriber is provided, such that, the result from an environment sensor system is used in the channel estimation. Using the environment sensor system, the propagation behavior of the wireless communication in the vicinity of the motor vehicle is recognized and classified, the channel estimation being adapted on the basis of the classification of the propagation behavior.
摘要:
An interface device having a first connection to a vehicle communication unit which is designed to carry out a vehicle-to-environment communication is described, the interface device having a second connection to an infrastructure unit and a computing unit which is designed to convert the signals between the first and second connections. In addition, a vehicle communication unit equipped with the interface device and a use of a vehicle communication unit are described.
摘要:
An emergency call unit for a vehicle includes not only a detection unit, a position-finding unit and a control unit, but also a transmission unit for the repeated transmission of a locating signal to a rescue worker. In this context, the locating signal may correspond to the position of the vehicle, and the transmission of the locating signal is initiated by a trigger event. By way of example, the trigger event is a request from a rescue worker or is the detection of an accident.
