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.

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:
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.

Disclosed is a method for braking or stopping an electromotor which can be operated with direct current, such as a brushless direct current motor. If there is an error in the electromotor or in the electronic or mechanical units connected to the electromotor, the presence of definite error states is verified, and the electromotor is braked, by carrying out, taking into consideration a maximum loading capacity of an electronic control unit which is connected to the electromotor, at least temporarily, a control of the electromotor which is adapted to the detected, definite error state.
摘要:
Method for reducing a reaction delay time of a vehicle safety control device which makes interventions into the control of the vehicle as a result of a surrounding situation in which there is a risk of collision, wherein the vehicle safety control device makes a first intervention into the control of the vehicle before the surrounding situation in which there is a risk of collision is validated.
摘要:
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.

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.
摘要:
A method and a system are provided for transmitting data in a motor vehicle by wireless communication. The data from a first transmitting data node is divided, transmitted to a second receiving data node via at least two different communication routes, and reassembled upon being received. Redundant data is generated from the data to be transmitted, the redundant data allowing a reconstruction of the data to be transmitted in the event that a communication route fails. The redundant data and the data to be transmitted are transmitted via the different communication routes.
