摘要:
The invention relates to a method for learning traffic events (212, 213, 214, 215), said traffic events (212, 213, 214, 215) being transmitted to a data network using vehicle-to-X communication. The traffic events (212, 213, 214, 215) comprise position data and time data assigned to the traffic events (212, 213, 214, 215), and the traffic events (212, 213, 214, 215) are stored electronically in the data network. The method is characterized in that an individual storage duration is determined for each traffic event (212, 213, 214, 215), and the traffic event (212, 213, 214, 215) is deleted from the data network after the storage duration expires. The invention further relates to a corresponding system and to the use thereof.

The invention relates to a sensor system for sensing the environment of a motor vehicle having an evaluation unit, wherein a grid-based environmental model is calculated and at least one discrete value is assigned to each grid cell. Discretisation is carried out by comparison of environmental data and at least one threshold value. At least one discrete value of the grid is preferably transmitted via a data transmission system in a vehicle to an evaluation or control unit.

The invention relates to a method for evaluating image data of a vehicle camera. Information about rain drops on a window in the field of vision of the vehicle camera is taken into account in the evaluation of the image data.

The invention relates to a method and to a device for determining whether a vehicle can pass through an object by means of a (spatially resolving) three-dimensional camera. At least one image of the surroundings of the vehicle is recorded by a three-dimensional camera. At least one path on which the vehicle is likely to move is ascertained. The image data of the three-dimensional camera is used to determine whether an object located on the path is recognised and whether said object has one or more connections to the ground. Upon determining a corresponding object, the dimensions and shape of the area or the space between object and roadway through which the vehicle is to pass according to the path are determined from the image data. By comparing the dimensions and the shape of the entry area or the space to be passed through with the dimensions and shape of the vehicle, it is determined whether and how the vehicle can pass through the object and further suitable actions can be taken.

The invention relates to a method for assisting a traffic light phase assistant of a vehicle (10), which detects the traffic light phases of a traffic light (11) by means of a camera (1). According to the invention there is provision that when a traffic light (11) is detected in the field of vision (1a) of the camera (1) the length (L) of the travel path (W) in the direction of the traffic light (11) which keeps the camera (11) in its field of vision (1a) is determined by means of a control unit (3), and a control signal (St) which relates to the length (L) of the travel path (W) is output.

The invention relates to a method for recognising marked hazard areas and/or construction areas in the region of carriageways, in which method by means of at least one environment sensor the objects indicating hazard areas and/or construction areas are detected. According to the invention a traffic light system is detected by means of the environment sensor, the positional data of the traffic light system is determined, an environment scenario in respect of the environment structure is determined from the environment data detected by the environment sensor and is compared with a reference model of the environment scenario. If said reference model indicates no traffic light system or indicates a traffic light system having positional data differing from the positional data of the detected traffic light system, a conclusion is drawn about a traffic light system identifying a hazard and/or a construction area.
