摘要:
The invention specifies a method for displaying a vehicle environment with at least two levels of resolution for a vehicle. The vehicle comprises a sensor system for detecting the environment and at least one driver assistance system. The environment model is designed as a probability grid having a plurality of grid cells. Data from at least two grid cells are combined at a high resolution level and are stored in a grid cell at a lower resolution level.

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 automatically detecting a driving maneuver of a motor vehicle (A), in particular during a passing maneuver or an evasive maneuver, wherein the vehicle environment is captured and an electronic image is produced thereof, the electronic image is used to detect a lane and/or road and objects (B, C) in the surroundings of the vehicle, longitudinal and transverse dynamic movement information ( Ψ, a y , δ H , ω FL , ω FR , ω RL , ω RR ) of the motor vehicle (A) is determined, and the position (X) of the motor vehicle (A) is estimated odometrically on the basis of the data (b Lane / Y Lane / θ , C 0 ) from the lane and/or road detection and/or from the movement information ( Ψ, a y , δ H , ω FL , ω FR , ω RL , ω RR ) of the motor vehicle (A). According to the invention, a) the following indicator variables are formed from the estimated position data (X) of the motor vehicle (A): a lateral distance value (LO L , LO R ) of the motor vehicle (A) from a lane or road marking (L), a time-to-collision value (TTC A,B ) relative to the distance ( d ) from the object (B) located in the driving direction, in particular from the vehicle ahead (B), a longitudinal dynamic passing or evasive maneuver (I), formed from the indicator variable (TTC A/B ) of the time-to-collision value and a value corresponding to the positioning (FPS) of the gas pedal of the motor vehicle (A), and b) threshold values (I th , TTC A, B, th ) are determined for said indicator variables (LO L , LO R , TTC A,B , I) to be used as criteria both for detecting partial maneuvers of a passing or evasive process, in particular of a following process, a lane change, passing a stationary or moving object (B) and changing into the lane of the passed object (B), and for detecting transitions between said partial maneuvers.

The invention relates to a method for displaying vehicle surroundings for a vehicle (1) having a sensor system for detecting the environment, wherein a boundary of a traffic lane on which the vehicle is currently being driven is displayed by position points (4, 7, 8, 11) that have a predefined set of attributes.
