Definitions

  • the invention relates to a device or method according to the preamble of the independent claims.
  • a device is already known, which recognizes by means of a camera present in the vehicle signs that indicate that the vehicle a wrong driveway on a highway or expressway, which would lead to driving in an unacceptable direction selected , This information is further compared with a navigation system and a GPS signal.
  • a warning is issued to the driver, be it visually or acoustically, and further the warning is wirelessly transmitted to receivers in the vicinity of the vehicle.
  • the generic DE 10 2004 060 432 AI shows a system for detecting exits, this being accomplished in particular with a lidar system.
  • Claim has the advantage that a system for detecting branches / exits / driveways is used to determine whether the own vehicle on the proper lane or in the
  • Driving direction can also be detected on a normal two-lane road. If necessary, it must be taken into account here that this is permissible or
  • desired driving styles can act, such. B. an overtaking process.
  • Directional roadway may be the detection of a turn on the unexpected Page as a more or less valid indication that a driving in an unacceptable direction is present.
  • the tracks are determined from the image, or, as in the present case of the invention, branches. These branches can also be branching tracks. However, these must be tracks that change into a separate road or lane and not z. B. to act on a track widening on the same road.
  • a rear-facing camera may be used which houses the rearward travel space (e.g.
  • the plausibility check with measurement results of other systems to be able to perform a reliable detection of a possible wrong driving.
  • branches to appear on the seemingly wrong (unexpected) side and thus an inappropriate reaction of the system according to the invention would be caused.
  • Such a case study is the (in Germany few) exits on highways, which branch off to the left of the road.
  • Another source of error are motorway junctions, where lanes can correctly branch off to the left. Possible combinations of such signals from other systems are described below. It is advantageous to use a digital map, such as in navigation systems on board the vehicle or over
  • GPS signal can be extracted from the data of the digital map, when or where in the further course of the route branches are to be expected. Also, the side on which the diversion is to be expected, can be determined from this and a false reaction of the system in the case of the aforementioned few exits on the left side, or motorway junctions are avoided.
  • Determining whether the vehicle is traveling in the wrong direction of travel can usually not be determined solely from the digital map due to the inaccuracy of the GPS signal. This is possible only through a further sensor system, such as the previously proposed optical camera of a lane detection system. Since the digital map already knows when or where the branches are to be expected, the camera or the image evaluation algorithm can be prepared accordingly in order to activate branch detection
  • This temporary activation can advantageously be used to save resources of the image evaluation system, since a branching detection algorithm does not have to be calculated if no branches are to be expected.
  • a light detection system which detects typical lights that have a meaningfulness about driving in (not) allowed direction of travel. This applies to headlights or taillights of others Vehicles, in particular those driving on their own lane or own lane. If taillights are to be recognized there, it can be assumed that the vehicle is driven in the permissible direction of travel. Are however

  • Ghost driver warning signs are recognized, which become visible when driving on or when entering a lane in an unacceptable direction of travel. To detect backs of traffic signs whose outlines can be used in the absence of traffic sign symbol, if necessary. Also
  • the previously presented camera can be used with a suitable image evaluation algorithm.
  • an object recognition system with which objects can be detected, or whose movement is typical, when the own vehicle moves in a permissible or impermissible direction of travel.
  • other vehicles can be recognized as such objects, whereby it is checked whether they meet the own vehicle or not.
  • the previously mentioned light detection system does not work in any case, for example, during the day when the lights of other vehicles are turned off. Again, the previously mentioned camera can be used again.
  • other object detection sensors such as radar-based systems.

  • a reaction of at least one system takes place in the vehicle.
  • a warning can be issued to the driver of the vehicle driving in the wrong direction, be it visually, acoustically or haptically.
  • other road users can be warned (also visually, acoustically or haptically), possibly also by car-to-car communication.
  • a message to authorities or infrastructure systems take place, which is carried out for example by means of data transmission (C2I).
  • active measures can also be initiated which intervene in the driving behavior of the vehicle in order to end driving in the wrong direction of travel or to maneuver the vehicle into a less dangerous position.
  • a debouncing can be carried out, which leads to the detection of a driving of the lane or the lane in an unacceptable direction of travel only when a certain number (> 1) of branches that have occurred on the non-expected side is detected.
  • the number of branches per time unit or more dangerous distance / distance can also be used as the debounce parameter.
  • the lane also known, technically outdated, lane indicates the area that is available to a vehicle for driving in one direction.
  • the lane is usually marked by road markings such as lane boundary and lane boundary or guideline. However, different lanes do not necessarily have to be marked. (Source: Wikipedia)
  • the roadway serves as a traffic space and is made up of the individual
  • Lanes and the edge strip together may be used by vehicles and forms the coherent, attached part of the
  • a road can consist of several lanes, which in turn can have several lanes.
  • Highways and highway-like federal highways are equipped with two so-called directional lanes, each with several lanes and side strips. The the
  • Road users oncoming roadway is also referred to as the opposite lane.
  • the two directional lanes are often separated by a structural device (for example a median strip with guardrail). (Source: Wikipedia)
  • a branch is presently a street or a piece of a road that leads away from an original street (branches off).
  • a road includes a road that just branches off from another lane and depending on the lane marker, there is also at least one lane of the
  • Special branches which are particularly suitable according to the invention, are exits (for example, from highways or expressways).
  • the lanes that appear to branch off the own lane and thus look like exits, or appear to have the function of an exit are in fact junctions for the traffic in the permissible direction (retraction) , The same applies vice versa, for the exits that appear like driveways.
  • the term branch or exit here can mean both according to the logic of driving in the right or not permissible direction of travel.
  • the side on which a branch is recognized refers to the side visible from the own vehicle in advance direction. Thus, exits in a receiving camera in advance in right-hand traffic on the right side in the image, ie to the right of the forward own lane / lane, to recognize.
  • Figure 1 shows a schematic structure of the system according to the invention
  • Figure 2 shows the traffic situation of a vehicle on a directional roadway with two possible lanes when driving
  • FIG. 1 shows a sensor system 11, for example a video camera, in which a unit recognizes branches 12, which can furthermore also determine on which side the branch occurs, in order to then compare them 13 with one Side on which the occurrence would be expected 14, when the vehicle is moving in the permitted direction of travel. This can be the detection of a
  • FIG. 2 shows a roadway which is a directional roadway 21 with two traffic lanes 22 for permissible driving in the same direction of travel (shown in the image upwards) 27. From this a branch 23a, which could be an exit in the present case, branches off and a junction 23b, which could be an entrance, branches off. A separate vehicle 24 travels in the situation 24a the left lane, in the situation 24b the right lane. If, according to the system of the invention, a branch 23 is detected, it is compared whether this occurred on the side on which it would have been expected 25.
  • the side referring to the road surface and not the lane is meant.
  • the system recognizes the branches regardless of whether the vehicle is traveling on the left or right (or possibly further existing middle) lane.
  • FIG. 3 shows a carriageway 31 with a directional lane in one direction 32 and an opposite lane 33 in the opposite direction of travel, as is usual on ordinary roads, each with a directional lane, for example highways.
  • the system recognizes a road 35 that branches off from this traffic lane on the unexpected side (namely on the left) and can thus initiate a reaction. If a branch appeared on the right-hand side of the roadway, the system would not carry out an assessment since the branch on the right-hand side does not branch off from its own (left-hand) lane but from the right-hand traffic lane.
