The invention relates to a method for identifying traffic-relevant information (I) in a moving vehicle. According to said method, sensor data (B) of a sensor (3) and map data (K) of a navigation system (4) are interpreted for identification. According to said method, the sensor data (B) are scanned for traffic-relevant information (I) contained therein in a first scene interpretation (10) and are compacted to relevant sensor data (Br), the map data (K) are scanned for traffic-relevant information (I) contained therein in a second scene interpretation (20) and are compacted to relevant map data (Kr), and the relevant sensor data (Br) and the relevant map data (Kr) are supplied to a control system (40) for interpretation of the sensor and map data, said control system (40) evaluating the sensor data (Br) and the map data (Kr) and outputting an output signal corresponding to said evaluation.
摘要:
A sensor device for detecting a motion state of a motor vehicle. The sensor device includes at least one laser unit having a light source for emitting coherent light which is transmitted in the direction of a roadway surface, and an interference detector which is designed to detect at least one measurement variable which characterizes interference between the light scattered at the surface and the light of the light source. The measurement variable represents a speed component of the sensor device and/or a distance between the sensor device and the roadway surface. The laser unit is coupled to an evaluation device which is designed to determine, from the measurement variable, at least one variable which characterizes the motion state of the vehicle, in particular a speed component of the center of gravity of the vehicle, a rotational angle or a rotation rate of the vehicle.

The invention relates to a method and a device, suitable for carrying out said method, for identifying traffic-relevant information (I) in a moving vehicle. According to said method, image data (B) of a visual sensor (3) and map data (K) of a navigation system (4) are pre-evaluated for identification and the results of said pre-evaluation are combined and interpreted. In order to allow a fast and modular processing of the signals, the image data (B) are scanned for traffic-relevant information (I) contained therein in a first scene interpretation (10) and are compacted to relevant image data (Br), the map data (K) are scanned for traffic-relevant information (I) contained therein in a second scene interpretation (20) and are compacted to relevant map data (Kr), and the relevant image data (Br) and the relevant map data (Kr) are supplied to a control system (40) and a state machine (50) for interpreting the image and map data, said control system (40) evaluating the image data (Br) and the map data (Kr) and transmitting an action (A) to be performed to the state machine (50), the state machine (50), as a response to the action (A) to be performed, carrying out a transition in its state space having previously defined states (Z) and outputting a piece of information (I) associated with the state (Z) or the transition.

The invention relates to a method for determining a direction of travel in a motor vehicle (100) with an accident prevention or preventive protection system (114), comprising the following steps: a) Recognition of an object (112, 121, 124) in front of the motor vehicle (100) in the direction of travel of the motor vehicle, b) Detection of possible contact of the motor vehicle (100) with the object (112, 121, 124) in accordance with the relative position of said motor vehicle and object to each other, c) Activation of a braking or steering process, which is independent of the driver, in accordance with the detection results with regard to possible contact with the object (112, 121, 124). In order to prevent accidental activation of the protection system, the following additional steps are included, according to the invention: e) Detection of the direction of travel of the motor vehicle by the preventive protection system (114) or by a safety device (116) connected thereto, and if travel in reverse is detected, inhibition or abortion of the braking or steering process which is independent of the driver.
