Abstract

The invention discloses a control device and a control method for a vehicle for avoiding wrong trips. The controller operates with an electronic storage device that stores information about the geographical course of lanes for the vehicle as well as their lanes including information about the direction of the lanes, an electronic device that determines the current position of the vehicle, an electronic device that the determines the current direction of travel of the vehicle, a data processing device that assigns the current position and the direction of travel to the geographical information and detects a current driving on the vehicle lane and recognizes a present or impending contradiction between the direction of travel of the vehicle and the direction of the driving lane, and with a signaling device that outputs a control signal in the presence of the contradiction.

Description

  • The The invention relates to a control device and a control method for a Vehicle for avoiding wrong-way driving according to claim 1 and claim 23rd
  • "Ghost drivers" are known a big threat to the Road transport. For example, in 1995 there were well over 300 accidents by vehicles nationwide, accidentally or in suicidal Intention to drive a lane in the opposite direction. there died over 50 people, about 250 were seriously injured and nearly 400 were easily injured.
  • Around to prevent such potential wrong-way drivers from finding a lane in the wrong direction, for example, become conspicuous warning signs erected, which, for example, by illustration of a skull on the deadly Indicate danger of entering the signposted exit of the carriageway the only for the opposite direction is provided. this concerns in particular, departures from highways where the danger accidentally driving in the opposite direction, is particularly large, because there the course of the streets through several changes of direction and adjacent freeways often very confusing is.
  • One further known, compared to the signs extremely rabiates and above addition, costly means are thorns in the surface of the Exit that extend out of the road surface, as soon as a vehicle enters the exit in the wrong direction threatens and triggers a photoelectric barrier, for example. This Although opposite signage has the advantage of hindering drivers, as a "test of courage" or suicidal Intention to enter the downhill, but for example reckless reverse travel on highways, if a departure was missed, can be with this Do not prevent resources.
  • Another means, which is like the signs to avoid accidental driving on a lane in the wrong direction, is for example from the DE 9415432 U1 known. It is a profile mat of elastomeric material, wherein the profile has a Sägezahnquerschnitt on the drivable upper side with steep flanks in one direction and flat flanks in the other, so that a motor vehicle driving the mat is put into noticeable and audible vibrations when the mat passes in the direction of the steep flanks, while vibrations are barely noticeable when driving over in the other direction.
  • Another remedy, which, like the thorns, is to avoid deliberately driving a lane in the wrong direction, is the DE 3324087 A1 known. It is an electronic security against false drivers in the exit area of a one-way street several electronic switching devices and a transmitter are arranged. Each vehicle traveling on the road is provided with an associated receiver and switching devices which immediately switch off the engine of the vehicle as soon as the vehicle passes and releases the switching devices arranged there in the "correct" sequence by incorrectly entering the one-way street. This triggers the transmitter, which sends a pulse to the receiver, whereupon the engine is stopped immediately. Although this device has the advantage over the thorn device not to damage the vehicle, but it requires as well as the thorn device and all other known means known a costly installation and is effective only in the installed location. However, installation at all vulnerable locations is impossible, at least for cost reasons, and in any event with respect to such statistically proven situations in which vehicles are deliberately turned on a highway lane to pass a "test of courage" or commit suicide.
  • Out DE 197 22 186 A1 For example, there is known a method of detecting a timing for operating direction indicator lights in automobiles. In the event that a vehicle is located in front of two side roads, the nearest of which is a one-way street with the opposite direction of travel, there is provided that premature setting of the direction signal lamp is prevented by turning on only after crossing the nearest one-way street. This prevents the driver from expressing his intention to turn off even before reaching the side road, in which he actually wants to turn by setting the turn signal, which can irritate other drivers. Thus, the method described therein has the goal of an incorrect direction indicator that could disturb or irritate other road users to the content.
  • Out EP 0 773 525 A1 a navigation device for a motor vehicle is known in which the road width is taken into account. Markings that refer to one-way streets, can be highlighted, where the appearance of the mark may depend on the direction of travel of the vehicle. However, an evaluation with respect to any wrong-way travel of the motor vehicle does not take place in the navigation device described there.
  • Finally is off DE 40 39 579 A1 a traffic monitoring system for stopping on a roadway against the prescribed there driving direction driving vehicles known. For this purpose, motion sensors are installed at the edge of the road, which detect the vehicle driving in the wrong direction and emit a control signal in the direction of the vehicle. This signal is received by the vehicle and then the vehicle is automatically braked and brought to a standstill.
  • In contrast, lies The invention has the object, an apparatus and a method for Control for to provide a vehicle for avoiding wrong trips, whose Effectiveness is improved.
  • These Task is achieved by a control device with the claim 1 formulated characteristics and by a control method with the solved in claim 23 formulated features. Advantageous embodiments The invention are specified in the subclaims.
  • The Control device according to the invention for a Vehicle has an electronic storage device for geographic Lane information, an electronic device for determining the current position of the vehicle, an electronic device for determining the current direction of travel of the vehicle, a data processing device and a signaling device for outputting a control signal. The Memory means in the manner of a road map in particular also information about stored the course and the direction of lanes of the lanes. The data processing device assigns the current position and the direction of travel of the vehicle this geographical information to and recognizes a currently used by the vehicle lane. The data processing device thus also recognizes in which Direction the vehicle drives on the lane and whether this direction of the prescribed direction of the lane corresponds. in case of a Contradiction - if Thus, the data processing device recognizes that the vehicle currently driving a lane in the wrong direction - causes the data processing device the signaling device to deliver the control signal to a Vehicle device such as the brake system of the vehicle, which then pressed is going to be the actual or to avoid imminent wrong-way driving.
  • A imminent wrong driving, the data processing device for Recognize example by analyzing the position data of the vehicle, the position of the vehicle in the immediately past time and describe the way and its direction. In this way, the data processing device on the one hand also the device according to the invention for determining the current direction of travel of the vehicle, on the other hand let yourself from this positional data with some certainty the direction of the immediately preceding path determine the vehicle takes. From this the computing device can calculate whether a contradiction between the direction of travel of the vehicle and the direction of a lane threatens, so imminent, on which the vehicle drives.
  • alternative the data processing device according to the invention signals evaluate further vehicle devices. For example, can the turn signal of the Vehicle in signal communication with the data processing device stand so that the Data processing device announced by the turn signal, planned change can assign the direction of travel to the geographical information and thereby the threatening contradiction between the direction of travel of the Vehicle and one according to the geographical information in the direction of travel lying, oppositely directed lane recognizes. Turn signals can but also by a steering angle sensor according to the invention on the vehicle come, not just, like the turn signal, an intended but an actual Indicates direction of travel and / or direction change, so that the threatening Contradiction for the data processing device is recognizable. A condition sensor On the manual transmission can also recognize when the vehicle for Example on a highway from his drive in the right direction in reverse switched and therefore in reverse To go wrong threatening.
  • When assigning the current position of the vehicle to the geographical information, the data processing device can detect an area of a junction currently being traveled by the vehicle in an oppositely directed lane, ie the exit area of a motorway exit or another one-way street. The signaling device can then deliver and cause the control signal, which is displayed on a display, which can be arranged according to the invention in the field of vision of the driver in the driver's seat of the vehicle, a corresponding warning. Also, an inventive electronics for voice output in the driver's seat of the vehicle can be stimulated by the output control signal to pronounce a warning. The vehicle devices described, that is, both the display and the voice output can, of course, not only in the impending wrong driving described but also in a present, by the data processing device he Wrong wrong drive could be triggered by delivery of the control signal.
  • The Control signal according to the invention to different Vehicle devices be addressed by the signaling device with one or more of these vehicle devices in signal communication stands, wherein the vehicle devices either electrical or electronic devices are or are electronically controllable. By the output to the vehicle device control signal is the Vehicle device actuated, around the threatening or actual To avoid wrong driving: The power delivered to the engine of the vehicle Control signal can throttle and / or stop the engine, the Engine for example by means of electronic injection electronically can be controllable. The delivered to the transmission of the vehicle Control signal can cause the transmission to its translation decreasing and thus slowing the ride of the vehicle, taking the transmission e.g. as a shift-by-wire circuit can be electronically controlled. The output to the brake system of the vehicle control signal can the operation effect the brakes, the brakes being e.g. as a hydraulic brake system can be controlled electronically. The output to the clutch system of the vehicle control signal can the opening of the Cause coupling, this e.g. as a hydraulic clutch electronically can be controllable. The to the hazard warning lights, the horn and / or the lighting of the vehicle output control signal can the hazard warning lights, sound signals and / or Lichthupsignale trigger, wherein Hazard warning lights, horn and lighting as electrical equipment electronically are controllable. In a further possible embodiment the vehicle on a radio signal transmitter, which delivered to the transmitter Control signal sending a warning signal to a receiver outside of the vehicle, e.g. to a street guard or the police. In this case, by selecting a suitable radio frequency, e.g. the conventional one Police radio can be achieved. Also a broadcast of the warning signal Radio stations with traffic is conceivable according to the invention.
  • According to the invention, the Control by means of a locking device the state for a determinable Duration of time spent on the vehicle devices as described triggered by the control signal can be. The corresponding unlocking device is included preferably not arranged in the region of the driver's seat of the vehicle, but e.g. only for the street watch or the police accessible in the engine compartment. In this way can be prevent one from the controller according to the invention stopped wrong drive of the vehicle by the driver intentionally again is recorded.
  • The Position determining device of the control according to the invention is preferably a GPS (Global Positioning System) [Global Positioning System] or DGPS (Differential Global Positioning System) with increased accuracy. Details about the DGPS can For example, be taken from the Internet at the address "http: www.waypnt.com." The direction of travel determination device preferably has a CN (Computerized Navigation) [computer-assisted navigation] interface card on. By using such known, proven and widespread components let yourself assemble the controller according to the invention extremely cost-effective. By connecting to a well-known CAN bus, others can be Integrate known CAN functions in the control according to the invention.
  • The Data processing system preferably also has algorithms for Description of the preceding road course, such. Distances on certain events (tunnels, bridges, junctions, construction sites, change the number of lanes, etc.). In addition, road attributes can be left involved in the control, e.g. the street class (Highway, federal highway, interchanges from highways or expressways, Locality) or the maximum speed allowed. The required data is received the data processing system of the preferably GPS-based storage means in the form of "digital road maps" on the storage medium.
  • Compared to the The prior art additionally includes the control according to the invention the advantages arising from the context shown here in particular the following advantages. At the lanes are no additional construction measures required for the function of the control. To inhibit wrong-way driving find no damage to the vehicle instead of. The controller can be in all geographical areas, for which corresponding "digital Road maps ", independently of weather, night and visibility Find use. In this case, the control according to the invention acts to prevent False drives not just like conventional ones Systems in the area of motorway exits, but causes these Prevention also reliable throughout the course of highways where e.g. to turn a driver over because of a congestion on the highway or drive backwards wants to get back to the last exit. Also the detection Such a wrong-way driver is possible, who is initially in correct direction of travel is located on a motorway exit, then but back against the direction back to the highway goes with it the intention to continue on the highway but still his way.
  • It is also important that even with one of the Driver disabled navigation function, the control device according to the invention and the control method according to the invention are activated. Thus, the backup against wrong trips in the background is active, without this feature is noticed by the vehicle occupants in normal driving.
  • The Description has been directed essentially to a control according to the invention an automobile to avoid wrong-way driving. The control according to the invention but is also on other vehicles, e.g. Ships, conceivable where up busy waterways and there furnished "one-way streets" also needed for the inventive device can arise. In that case, the device referred to in the claims as the "driver's seat" is more general as a driver's cab or to understand other appropriate equivalent.
  • A preferred embodiment The invention will now be described with reference to the accompanying drawings described.
  • 1 schematically shows the top view of a traffic situation with a wrong-way driver in a one-way street,
  • 2 schematically shows the top view of a traffic situation with a wrong-way driver in a descent of a highway,
  • 3 schematically shows the top view of a traffic situation with two cars that threaten to turn on a highway and
  • 4 schematically shows a block diagram of a control according to the invention for avoiding wrong trips.
  • In 1 . 2 and 3 are schematically illustrated traffic situations with vehicles 2 . 2 ' . 2 '' either in the wrong direction in a one-way street 4 drive ( 1 and 2 ) or on a highway 6 threaten to drive in the wrong direction by fully turning the steering ( 3 ). This is in 1 . 2 and 3 Traffic situations represented, which usually represent a major threat to road users and where the danger by means of a control device according to the invention 8th ( 4 ) in the vehicles 2 . 2 ' . 2 '' is mounted and according to the control method of the invention 8th ( 4 ) works, can be significantly reduced or even averted.
  • First, referring to 1 is a vehicle 2 recognizable from a two-lane road 10 in a one-way street 4 is inflected, and contrary to the direction of the one-way street 4 , what about the signs 12 at the exit of the one way street 4 is recognizable. The device according to the invention 8th for avoiding wrong trips causes in this situation immediately after the vehicle retracts 2 in the one-way street 4 that the engine of the vehicle 2 stops, whereupon, by the action of the engine brake, the vehicle 2 from its slow ride immediately after turning into the one-way street 4 comes to a halt. The device according to the invention may be actuated to warn of the one-way street 4 oncoming vehicles the vehicle's horn, flashlight and hazard warning lights 2 and shows after the vehicle is at a standstill 2 in a display in the field of vision of the driver of the vehicle 2 the request to: "Reverse!". Before accidentally turning into the one-way street 4 was the driver of the vehicle 2 Already warned of the impending risk by the display indicated: "Oncoming right one-way street! Do not turn right!". The driver of the vehicle 2 but had overlooked this warning. As soon as the driver now follows the request to engage the reverse gear, the motor stopped by the device is released again and, according to a request on the display, "start the engine and drive backwards out of the one-way street!" the driver can use the vehicle 2 Move backwards out of the danger zone. The displays on the display are supported according to the invention by appropriate announcements of a speech output electronics.
  • Should the driver fail to comply with the request to reverse out of the one-way street within a certain time, eg 15 seconds, this indicates that he is either unable to follow the request, for example because of a powerlessness, or the request does not want to follow, but, for example, a supposed "shortcut" in the opposite direction by the one-way street 4 has in mind. In this case, after the specified time, the starting of the engine is not released again, but can only be made by the police, the road patrol or other authorized personnel, eg with special tools. The staff is called by sending a radio signal through the device.
  • The described interventions in the drive of the vehicle 2 as well as the display displays and voice prompts described are effected according to the invention as follows. The vehicle 2 is equipped with a GPS system which shows the current position of the vehicle 2 determined in the form of geographic coordinates. Furthermore, the vehicle points 2 a compass-like Einrich tion on which the current orientation of the vehicle 2 , ie its direction of travel, determined. Both data are made available to a CAN system, namely a data processing system with a data memory, on which "digital road maps" are stored with information about the geographical course of lanes and their lanes including information about the direction of the traffic lanes also for the area, in which is the one-way street 4 and the street 10 are located. The data processing device orders the respective current position and direction of travel of the vehicle 2 the geographic information and recognizes the currently of the vehicle 2 busy lane, that is, first of all the lane of the road correctly traveled with respect to their direction 10 and after turning off the one-way street 4 and the contradiction between the direction of travel of the vehicle 2 and the prescribed direction of the one-way street 4 , Then, from a signaling device of the device according to the invention, which is triggered by the data processing device, a control signal to the electronic injection of the engine of the vehicle 2 given to stop the engine, and a second control signal is given to the circuit of the display and to the electronics of the voice output to make the above request to reverse when a vehicle speed sensor has supplied to the data processing device the signal that the vehicle 2 stands. Once a condition sensor has signaled at the switch gear that the reverse gear is engaged, another control signal gives the engine free to start again. This release is limited by a corresponding timing algorithm in the data processing device in time to the specific time of, for example, 15 seconds. Subsequently, as described above, the engine can only be restarted by means of a special tool.
  • The above-described warning before the confluence of the one-way street 4 that indicated the display while the vehicle 2 still on the street 10 was triggered by another control signal, after the data processing device by calculating the road ahead due to the data from the "digital road map" the junction of the one-way street 4 had recognized.
  • Regarding 2 is a vehicle 2 recognizable from a two-lane road 10 in a one-way street 4 enters, namely accidentally in the opposite direction in a descent 4 a highway 6 , The control sequence according to the invention is essentially the same here as with reference to FIG 1 has been described. Immediately after the vehicle has entered 2 in the motorway exit 4 stops the engine of the vehicle 2 Here, however, because of the faster ride of the vehicle 2 the braking distance compared with the situation after 1 is slightly longer and therefore the braking by the brake system of the vehicle 2 is supported, which is triggered by the same control signal as that which causes the engine to stop.
  • Regarding 3 are two vehicles 2 ' and 2 '' recognizable on lanes of a highway 6 drive slowly in the correct direction. Both vehicles are equipped with a control device according to the invention, as to 1 has been described. The slow drive of the vehicles 2 ' . 2 '' it is recognizable that both vehicles 2 ' . 2 '' drive with fully turned steering, so are just about to, on the highway 6 to turn. The vehicle 2 ' drives from the hard shoulder of the highway 6 with full impact to the left on the lanes of the highway 6 , and the vehicle 2 '' drives from the fast lane of the highway 6 with full impact to the right in the direction of the streak. Both driving situations mean the highest risk for the traffic involved. A mistake on the part of the driver is essentially excluded. Probably deals on purpose. Accordingly, the display in the field of vision shows the driver of the vehicles 2 ' . 2 '' to "Alarm! Continue straight ahead!". On both vehicles, the control according to the invention immediately triggers the hazard warning lights and the flashlight. The vehicle 2 ' that to the turning maneuver to the left very far to the right on the highway 6 that is, located on the hard shoulder or in the right lane of the right lane is also stopped within a very short time after the alarming display indication by immediately stopping the engine and full braking and prevented from continuing by releasing the engine to restart as above to 1 described, can only be done by means of special tools.
  • The vehicle 2 '' is the turning maneuver to the right very far left on the highway 6 that is, in the fast lane, where an immediate emergency stop would be particularly dangerous, because on this track is usually driven very fast. That's why it's on the vehicle 2 '' the engine is not stopped immediately, but allowed to continue slowly until the direction of travel device determines that the device has completed the turn of the vehicle by 180 °, whereupon the vehicle 2 '' on the hard shoulder or at least very far right on the highway 6 , So in a less dangerous area, must stand, or until the condition sensor on the transmission reports that the reverse gear is engaged, indicating that the turning maneuver should be continued by resetting, causing the vehicle 2 '' again in the left on the highway 6 larger danger area or that the reverse drive should now be started in reverse, or until the vehicle speed sensor reports that the vehicle 2 '' stands. Thereupon also on the vehicle 2 '' by stopping the engine, the onward journey is initially blocked. The driver may have the option to continue at a predetermined crawl speed.
  • The too 1 . 2 and 3 Exemplary control processes are described with reference to 4 by a controller shown schematically there in a block diagram 8th realized. The control device 8th has an electronic storage device 14 containing information about the geographical course of carriageways 4 . 6 . 10 for the vehicle 2 . 2 ' . 2 '' as well as the lanes of the lanes 4 . 6 . 10 including information about the direction of lanes stores, as well as an electronic device 16 , z. As a GPS, the current position of the vehicle 2 . 2 ' . 2 '' certainly, an electronic device 18 indicating the current direction of travel of the vehicle 2 . 2 ' . 2 '' determines a steering angle sensor 20 , a turn signal 22 and a circuit state sensor 24 , The signals and information from the storage means 14 , the electronic devices 16 . 18 , the sensors 20 . 24 and the turn signal 22 processes a data processing device 26 , which assigns the current position and the direction of travel to the geographical information and thereby a current from the vehicle ( 2 . 2 ' . 2 '' ) recognized lane and the one present or imminent contradiction between the direction of travel of the vehicle 2 . 2 ' . 2 '' and recognizes the direction of the busy lane. A signaling device 28 gives in the presence of the contradiction, a control signal 30 to a vehicle device 32 For example, the engine, the transmission, the brake system, the clutch system, the lighting system, the horn, the display and / or the electronics for voice output, from. A locking device 38 keeps the state, by the control signal 30 on the vehicle device 32 was triggered for a determinable period of time. The condition may be due to a reset signal 40 be terminated, by means of a release device 42 is given to the vehicle device. The operation of the unlocking device 42 may be beyond the control of the driver of the vehicle 2 . 2 ' . 2 '' lie. About a transmitter 34 gives the signaling device 28 in case of opposition also a warning signal to a receiver 36 , for example, in a police radio center, from.
