Definitions
- the invention relates in particular to a method and a device according to the preamble of the relevant independent claim.
- a known headlight system of a motor vehicle allows the light distribution to be changed by pivoting the headlights. This pivoting depends on the steering wheel angle of the vehicle. This allows earlier detection of potential obstacles in the travel path of the motor vehicle.
- the object of the invention is to improve such a method or such a device.
- An essential aspect of the invention is the implementation of the following measures for controlling the light distribution of a motor vehicle.
- the driving environment in front of the vehicle is detected by a camera system provided on the vehicle. This is preferably done in the dark and / or in adverse weather conditions, such as rain or fog, which are associated with a poorer view.
- the digital data provided by the camera system are fed to an image processing system provided in the vehicle.
- the image processing system checks whether the detected object or the detected objects are potential obstacles in and / or on the edge of the current travel path of the vehicle. If the image processing system classifies the detected object or objects as a potential obstacle, the image processing system causes a change in the light distribution in a third step. at least a vehicle headlight to illuminate or illuminate the potential obstacle.
- the camera system has a detection range that is greater than the range of at least the current light distribution of the headlights of the vehicle. This leaves enough time to recognize a potential obstacle with the help of the image processing system and to illuminate it in time or to change the light distribution accordingly.
- the camera system detecting near infrared, far infrared, preferably a combination of visually visible light and far infrared or also a combination of visually visible light and near infrared.
- near infrared infrared radiation with a wavelength in the range from approx. 800 nm to approx. 2.5 ⁇ m
- far infrared infrared radiation with a wavelength of approx. 7 to 14 ⁇ m, preferably approx. 10.5 ⁇ m.
- Inexpensive sensors or camera systems are available for the detection of infrared or thermal radiation, the detection range of which is sufficiently large in the aforementioned sense.
- CCD sensor charge-coupled device
- the camera system detects objects on the basis of the thermal radiation emitted by them and determines their position in relation to the lane of the vehicle.
- the lane can be determined, for example, by road boundary lines visible in the infrared image and a corresponding pattern comparison by the image processing system according to the invention recognized or determined.
- human or animal objects on the right-hand side of the roadway are also detected by the camera system on the basis of the heat radiation they emit.
- the corresponding digital data are analyzed by the image processing system according to the invention with regard to the temperature and / or other characteristic properties, such as the outline. Possibly. the image processing system classifies the object or objects according to a temperature and / or pattern comparison as human and / or animal objects and causes them to be illuminated or illuminated.
- the light distribution of the vehicle is influenced alternatively or additionally by at least one vehicle dynamics variable.
- This can be, in particular, the speed of the vehicle and / or its steering angle and / or a variable dependent on the vehicle position.
- the vehicle position can be determined, for example, using a satellite navigation system, such as a GPS system in the vehicle.
- the consideration of one or more dynamic driving variables leads to a further improvement in the light distribution, in particular a faster adaptation to the current driving conditions.
- the light distribution of a headlight or both headlights can be influenced or controlled in the manner described by the image processing system according to the invention and / or a corresponding control.
- the headlight (s) can be, for example, a vehicle headlight that has a specially designed reflector or a specially designed reflector area.
- the specially designed reflector or reflector area can, for example, be pivotable and / or have an array or field of (individually) electrically “pivotable” micromirrors that are influenced by the image processing system according to the invention or a control system cooperating therewith for the aforementioned purpose
- the desired light distribution or the desired illumination or illumination of the potential obstacle can be achieved.
- a reflector of a vehicle headlight having a micromirror is known.
- a headlight separate from the front headlights which has a reflector which is pivoted by the image processing system or a control cooperating therewith.
- a headlamp with micromirrors as described above, which are “pivoted” by the image processing system according to the invention or a control system cooperating therewith for the aforementioned purpose.
