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 determining a roll angle of a motorcycle. Said method is characterized by determining a rolling rate (Formula A) of the vehicle, especially by means of a rotational speed sensor, determining a first roll angle (λ1) from the rolling rate (Formula A), determining at least one additional variable that is characteristic of the driving dynamics, especially a speed (v) and/or a rolling rate (Formula A) and/or an acceleration (Formula C, Formula D) of the vehicle, determining, based on this/these variable(s) that is/are characteristic of the driving dynamics, at least one second roll angle (λ2) and calculating from the roll angles (λ1, λ2), especially by addition (15), the roll angle (λE). The invention also relates to a device for determining the roll angle of a motorcycle.

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.
