Definitions

  • the present invention relates to a method for controlling a lighting device of a vehicle and a computing unit and a computer program for its implementation.
  • Modern (motor) vehicles contain functions that activate the exterior and/or interior lighting of the vehicle when, for example, the locked vehicle is unlocked using a (radio) key. Such functions are known, for example, as “Welcome Light” or “Welcome Home Light”. Such functions can be used, for example, to make it easier for an approaching driver to find a parked vehicle.
  • the present invention makes use of the measure of specifically and explicitly determining the current position or information regarding this position of a person entering or leaving the vehicle and using the lighting device specifically and explicitly this current, actual position of the respective person as well as in particular to illuminate certain areas in the environment around the person.
  • a route starting from the current position of the person away from or towards the vehicle can advantageously be illuminated, so that the respective person can find this route particularly easily and also obstacles on this route such as holes, bumps, puddles, etc. early on , can be recognized clearly and reliably.
  • the invention therefore enables safe and comfortable moving to and fro for boarding and alighting of passengers from vehicles, particularly in poor visibility conditions.
  • the vehicle lighting is activated independently of the position of a person approaching the vehicle or moving away from the vehicle. It is therefore not possible to illuminate specific areas in a targeted manner with such conventional functions, in particular no areas specifically related to the position of the respective person. Instead, an area directly in front of or around the vehicle is statically illuminated using such conventional functions.
  • the present invention makes it possible to specifically illuminate the current position or areas of interest of the respective person with the aid of the position information.
  • Dynamic control of the lighting device or dynamic adjustment of the lighting for example dynamic adjustment of the light distribution, shape, range, brightness etc. of the lighting, to the current, possibly changing position of the respective person is made possible in a particularly expedient manner.
  • This targeted lighting makes it particularly useful to avoid unintentional lighting or blinding of sensitive areas and unnecessary light pollution.
  • the illumination of the position of the person can take place in particular with high or maximum intensity, luminosity and range, so that the person can clearly see the environment around him without dazzling and unnecessary illumination of sensitive areas occurring.
  • the lighting device can be activated when the person approaches the vehicle from a great distance, for example, in order to guide the person along a "light path" to the vehicle, for example by means of targeted spots.
  • a "light path" to the vehicle, for example by means of targeted spots.
  • the lighting device can be headlights and/or ambient lighting.
  • the lighting device can, for example, be controlled in such a way that a direction and/or orientation and/or brightness of a headlight cone is adjusted, e.g. by rotating or moving individual headlights or e.g. by activating or deactivating individual parts or areas of the headlight.
  • the headlight can be designed as a matrix headlight, with a large number of individual light sources, e.g. individual LEDs, being arranged in a matrix or table form.
  • Such a matrix headlight can be controlled, for example, in such a way that individual light sources are activated in a targeted manner and other light sources are in turn deactivated in a targeted manner.
  • technologies of intelligent lighting systems can be used to control the lighting device, e.g. active cornering lights, adaptive cornering lights, cornering lights, freeway lights, fog lights, off-road lights, etc.
  • Determining the position information advantageously includes determining the position of the person.
  • the current, actual position of the person is thus determined, e.g. in spherical coordinates or Cartesian coordinates.
  • the position can be determined, for example, as an absolute position or relative to the vehicle or in relation to the current position of the vehicle or the lighting device.
  • determining the position information advantageously includes determining a change in position or a change in the position of the person.
  • a movement of the person per se can be recognized and a direction, speed and/or acceleration of this movement can also be determined.
  • a velocity or acceleration vector can be determined for this purpose.
  • it can be determined whether or how quickly the person is moving away from or towards the vehicle.
  • determining the position information advantageously includes determining a direction of the person, in particular a direction of movement or a direction of the change in position, a viewing direction and/or a head direction. In particular, it can thus be determined in which direction the person is currently looking or in which direction the person is currently moving.
  • Determining the position information preferably includes extrapolating and/or predicting one or more future positions of the person. For example, an expected position at a future point in time or after a specifiable prediction, look-ahead or extrapolation time interval can be estimated based on the current position and the detected movement or change in position. For example, an expected path of the person can be estimated as a sequence of multiple future positions based on the current position and the detected movement or change in position towards or away from the vehicle. For example, such extrapolations or predictions can be carried out depending on the determined current position and on the determined speed or acceleration vector and a predeterminable (extrapolation) time interval. In particular, these extrapolations can be computer-implemented using appropriate extrapolation algorithms.
  • Controlling the lighting device as a function of the specific position information preferably includes illuminating the specific position and/or an area extending from the specific position of the person in the specific direction by means of the lighting device.
  • the respective current position of the person as well as a respective area in the viewing and/or head direction or direction of movement can be illuminated directly in front of the person, so that the person can detect nits in their immediate vicinity at an early stage and reliably.
  • such lighting can be dynamically adjusted or tracked with changes in direction, so that, for example, a particular area is always illuminated directly in front of the person. The lighting can thus expediently follow a head movement of the person.
  • the head direction can be approximated as the viewing direction or field of view direction, particularly if, for example, the person's eyes are not in the detection range of the vehicle's camera but head.
  • the extrapolated or predicted future position(s) of the person are preferably illuminated by means of the illumination device.
  • An area to which the person is likely to move can thus be particularly expediently illuminated, so that the person can clearly identify and find the appropriate path and can also identify obstacles on this path early and reliably. If this extrapolated or predicted path is curved and winding, for example, these curves can also be adequately illuminated when the direction of movement of the respective person changes in the direction of these curves.
  • Determining the position information advantageously includes determining environmental information relating to an environment of the person's position.
  • this environmental information can relate to the ground or its nature around the person. For example, obstacles such as bumps, holes, puddles, etc. in the person's surroundings can be detected.
  • a distinction can be made between different types of subsoil, for example between asphalt, meadow, gravel, etc.
  • the environmental information can, for example, relate to objects located in the area surrounding the person. For example, buildings, buildings, open spaces, paths, streets, curbs, lane markings, traffic signs, people, vehicles, etc. in the surroundings are recognized.
  • the extrapolation of the future position or of the path to be covered can be carried out as a function of this specific environmental information. For example, based on detected objects or obstacles and based on the nature of the ground, it can be estimated which way the respective person will choose towards or away from the vehicle.
  • environmental information of this kind can be recorded or determined directly using sensors such as cameras and corresponding image analysis or image processing methods.
  • the environmental information can also be read out or obtained from data sets depending on the current coordinates of the vehicle, for example from map data stored in the vehicle or from a remote computing unit, for example via the Internet.

  • This determination of the first and second areas can expediently take place in each case as a function of the environmental information determined. Accordingly, the lighting device of the vehicle is controlled in such a way that corresponding first areas are specifically illuminated and corresponding second areas are explicitly not illuminated.
  • obstacles in the surroundings can be determined as such first areas, so that they are sufficiently illuminated and can be clearly recognized by the respective person.
  • reflection surfaces in the surroundings for example white walls, can be detected as the first areas.
  • Such areas can then be deliberately illuminated by means of the lighting device in order to generate indirect illumination of the current and/or extrapolated or predicted position of the person.
  • Such areas or reflective surfaces can be usefully included in the lighting, for example by means of the lighting device tion to be able to illuminate areas that cannot be directly illuminated. In particular, in this way shadows and also blinding of the respective person can be avoided.
  • Objects can be defined as such second areas, for example, which should not or should not be illuminated for safety reasons or to avoid, for example residential buildings or at least windows of residential buildings, hospitals, other people or road users, etc.
  • Other light sources can also be other light sources, for example, as second regions be recognized or areas which are already sufficiently illuminated by other light sources. Such already sufficiently illuminated second areas then do not need to be additionally illuminated by means of the lighting device of the vehicle. Illumination of such areas by means of the lighting device can then be omitted or at least reduced.

  • this can be a radio key that can communicate with the vehicle via a radio link.
  • a key is expediently registered in advance by the vehicle owner in the vehicle or paired with it ("pairing"). If the driver approaches the locked vehicle with this registered key, it can, for example, be automatically unlocked when the distance falls below a certain point. Conversely, the vehicle can be locked automatically when the driver moves away from the vehicle with the key and exceeds this certain distance.
