In a motor vehicle accident data memory and method of operating it, a reference time is determined by a satellite navigation system, and a system time is synchronized with the reference time. When an accident is detected, accident data and the system time are recorded in a non-volatile memory.

Method for operating a motor vehicle accident data memory and accident data memory system

A driver assistance system () for a vehicle includes a control unit (), and a communication device () for receiving data from a server (). The control unit () is configured to calculate a trajectory (T) for the vehicle on the basis of sensor data. The control unit () is also configured to replace the calculated trajectory (T) for the vehicle () with an offboard trajectory (T) received from the server () under certain circumstances.

Offboard trajectories for difficult situations

The present invention relates to a vehicle-to-X communication system for a vehicle. The vehicle-to-X communication system comprises a first communication module having a first antenna, wherein the first antenna has a first communication angle; a second communication module having a second antenna, wherein the second antenna has a second communication angle; wherein the first communication module and the second communication module are arranged in such a manner that the first antenna and the second antenna are oriented in different directions, in order to obtain a total communication angle which is composed of the first communication angle and the second communication angle.

Vehicle-to-X communication system

The invention relates to a communication device for vehicle-to-X communication for a vehicle, comprising: at least four antennas for transmitting and receiving wireless information and at least one electronic control unit (ECU) for transmitting and receiving information via the antennas and for processing the information received or to be transmitted via the antennas, wherein the at least four antennas are arranged on the vehicle in such a way that the directional characteristics of antennas among the at least four antennas which are arranged directly opposite each other on the vehicle exhibit a spatial overlap.

Communication device for vehicle-to-X communication

A method for verifying and/or preprocessing data packets received by a receiving device in a vehicle during wireless vehicle-to-environment communication includes: determining, in the receiving device, relevance of the received data packets; prioritizing, and verification and/or preprocessing according to their relevance, the data packets for the determination of the relevance depending on the distance between a transmitting device and the receiving device; and checking the signature of the transmitting device of the data packets and/or preprocessing the data packets in an order predefined by the prioritizing. The determination of the relevance also depends on the type of data packet and/or the type or position of the transmitting device, taking into account the position of the transmitting device based on another safety-relevant object.

Method for verifying and/or preprocessing data packets and control device set up to carry out the method

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.

Method and system for transmitting data in a motor vehicle

A method and a device are for prediction and adaptation of movement trajectories of a vehicle for assisting the driver and/or for preventing or reducing the severity of a collision. Situatively required movement trajectories for assisting the driver or collision avoidance are determined using an environment sensor system. Physically possible movement trajectories are determined from characteristic properties of the driving dynamics of the vehicle and from the coefficient of friction between the tires and the road up to a maximum coefficient of friction. An intersection between the above two sets of trajectories is determined, and only trajectories that are included in this intersection are taken into account for the prediction and adaptation of movement trajectories for the driving assistance or collision avoidance function.

Method and device for the prediction and adaptation of movement trajectories of motor vehicles

Disclosed herein is assistance, safety and navigation technology for vehicles. In particular, the disclosure relates to a vehicle system and a method for controlling the vehicle system.
