    摘要： The invention relates to a method for creating a current situation depiction, particularly a current city-centre situation depiction, in which environment data and/or map data and/or position data describing a locally bounded situation are sent to a database (16, 25) by a multiplicity of vehicles (12, 14, 22, 24) using vehicle-to-X communication means. The environment data are captured by means of ambient sensors and/or vehicle sensors, the map data are read from a digital memory, and the position data are determined at least by means of a global satellite position system. The method is distinguished in that the environment data and/or the map data and/or the position data are continually merged with a situation depiction that is already present in the database (16, 25) to form a current situation depiction, and both the database and the situation depiction are fixed in location. The invention also relates to an appropriate system.

    摘要： The invention relates to a lane keeping system for a motor vehicle (5), comprising: a lane detection system (6) for detecting and determining the lane (1, 1a) in front of the vehicle (5), a vehicle position determination system (7) for determining the vehicle trajectory (T, T
    0 , T
    1 , T
    2 ) by means of a motion variable of the vehicle (5), a control device (8) for producing a steering torque (M) that acts on the steering system (9) of the motor vehicle (5) for the purpose of lane keeping. According to the invention, the lane detection system (6) is designed to detect roadway edge and lane markings (3, 4), roadway edges, objects (10), in particular structural boundaries in the vicinity of the roadway edge and/or of the lane edge, and vehicles in adjacent lanes of the lane (1a) in which the vehicle (5) is driving; the control device (8) produces forecast points (x) on the vehicle trajectory (T, T
    0 , T
    1 , T
    2 ) and determines threshold values (S) according to the objects (3, 4, 10) specifying the surroundings situation in the vicinity of the forecast points (x) in regard to roadway edge and lane markings, roadway edges, objects, in particular structural boundaries in the vicinity of the roadway edge and/or of the lane edge, and vehicles in adjacent lanes of the lane in which the vehicle is driving; and the control device (8) determines a predicted distance (y
    prä ), which indicates the distance of the vehicle at the forecast point (x) on the vehicle trajectory (T, T
    0 , T
    1 , T
    2 ) from the object (3, 4, 10) specifying the surroundings situation at the forecast point. The invention relates to a lane keeping system for a motor vehicle (5), comprising: a lane detection system (6) for detecting and determining the lane (1, 1a) in front of the vehicle (5), a vehicle position determination system (7) for determining the vehicle trajectory (T, T
    0 , T
    1 , T
    2 ) by means of a motion variable of the vehicle (5), a control device (8) for producing a steering torque (M) that acts on the steering system (9) of the motor vehicle (5) for the purpose of lane keeping. According to the invention, the lane detection system (6) is designed to detect roadway edge and lane markings (3, 4), roadway edges, objects (10), in particular structural boundaries in the vicinity of the roadway edge and/or of the lane edge, and vehicles in adjacent lanes of the lane (1a) in which the vehicle (5) is driving; the control device (8) produces forecast points (x) on the vehicle trajectory (T, T
    0 , T
    1 , T
    2 ) and determines threshold values (S) according to the objects (3, 4, 10) specifying the surroundings situation in the vicinity of the forecast points (x) in regard to roadway edge and lane markings, roadway edges, objects, in particular structural boundaries in the vicinity of the roadway edge and/or of the lane edge, and vehicles in adjacent lanes of the lane in which the vehicle is driving; the control device (8) reduces or increases the threshold (S) according to the predicted distance (y
    prä ) in order to produce an engagement distance (S
    1 , S
    2 ); and if the lateral distance of the vehicle from the object (3, 4, 10) specifying the surroundings situation falls below the engagement distance (S
    1 , S
    2 ), a steering torque (M) is applied to the steering system (9), wherein the engagement magnitude depends on the lateral distance of the vehicle from the object (3, 4, 10) specifying the surroundings situation.
