Definitions

  • the invention relates to a motor vehicle comprising at least one device for outputting acoustic and / or optical information and an associated control device which determines the information to be output and controls the output.
  • emergency vehicles such as the police, fire brigade, medical services or municipal enterprises, which need to arrive at the scene as quickly as possible in emergencies, and can claim their right of way as a result, a blue light mounted on the roof and a bugle over which facilities are located Road users are informed of the approaching emergency vehicle and the drivers of these vehicles are required to pass the emergency vehicle as possible without hindrance.
  • the blue light or the horn is not early enough or not perceived by the drivers, especially if in the vehicle, for example, music is heard or the driver converses with other people in the vehicle. This may result in the emergency vehicle being forced to brake hard, evade, or seek another route because the motor vehicle that has not perceived the approaching emergency vehicle is not clearing the lane, thus blocking the path.
  • Another problem is that when recognizing the situation that an emergency vehicle is approaching, some drivers are often overwhelmed and do not know how to respond and, in particular, whether they have anything to react to. Because an emergency vehicle that drives in the opposite direction is usually irrelevant to the driver, he So he does not have to change his driving style. Nevertheless, it is often not possible to detect the situation, in particular solely via the acoustic signal of the emergency vehicle, for the driver.
  • DE 10 2004 027 953 discloses a driver assistance system for detecting an emergency vehicle approaching a vehicle.
  • the invention is therefore based on the problem to provide a motor vehicle that can assist the driver in detecting the situation depending on the same.
  • a motor vehicle of the type mentioned has a communicating with the control device receiving device for a vor marssdorfen emergency vehicle signal transmitted containing this emergency vehicle indicative and indicating the direction signal information, and that the control device for generating and Output of a behavior information for the driver is formed as a function of the received signal information.
  • the motor vehicle according to the invention uses the technically given possibility of "car-to-car communication", that is to say the wireless communication of vehicles with one another, which is preferably carried out on the basis of the WLAN standard. About this wireless communication option information can be exchanged between two vehicles. This circumstance is now making use of the motor vehicle according to the invention.
  • a receiving device preferably embodied as a combined transmitting and receiving device, via which a signal can be received from a pre-authorized emergency vehicle, which can be given continuously or intermittently.
  • This signal contains a plurality of signal information, a first, which generally indicates the presence of an emergency vehicle in the reception area of the own motor vehicle, and a second signal information, which indicates the direction of travel.
  • the signal or its signal information is now evaluated and behavioral information for the driver that may be of different nature is generated.
  • the heading information indicates that the emergency vehicle is on the opposite lane, for example, separated by a median strip (highway, multi-lane urban road, etc.), the driver can, for example, on a display that modern cars usually have a visual indication "emergency vehicle drives on opposite lane, no reaction required "or be acoustically output via a corresponding infotainment system via the radio loudspeakers. If it emerges from the direction information that the emergency vehicle is in its own lane, the information can be different depending on the relative position of the emergency vehicle to its own vehicle.
  • the driver receives an information which he can in any case record about the presence of an emergency vehicle in his immediate vicinity, as well as information which describes the further behavior required or recommended by him.
  • the system according to the invention works expediently even with a low equipment level of vehicles with corresponding transmitting / receiving devices with associated control device, since even the automatic transmission of only a few vehicles, in particular in the urban area, is advantageous in reducing any impediments.
  • Another circumstance is that many other road users who do not have a system according to the invention, are automatically oriented to the front or rear man. If this is equipped with a system according to the invention, it reacts expediently and appropriately so that the positive effect of the system can be increased by the "imitation" of other road users.
  • the behavior information contains information about the route to be selected directly, in particular for the formation of a driving lane for the emergency vehicle. From this information, the driver is freed from the self-made, often difficult, decision to make in which direction to avoid a lane and pass the emergency vehicle. Because according to the invention, the controller generates based on the information available to her a behavioral recommendation that indicates in which direction the driver has to evade, for example, to the right or left, depending on where he is to clear the tram, or in the crossing area, where may be instructed to continue straight ahead, provided that the situation is such that turning of the emergency vehicle is likely.
  • the signal information also contains information about the future driving route of the emergency vehicle, wherein the control device is designed to generate the behavioral information in consideration of this information.
  • This driving route information of the emergency vehicle is quasi a forward-looking, future route information about the route selected by the emergency vehicle to the destination, this information z. B. from an operational vehicle-side navigation system, in which the destination, ie where the emergency vehicle goes, is defined. If it is now known on the part of the control device in which direction the emergency vehicle wishes to drive, the behavior recommendation with regard to avoidance or the like can be generated in a more substantiated manner.
  • the controller may also consider this information.
  • the signal information includes the message that the emergency vehicle is on a three lane highway If the center alley wants to drive or drives, the control device can carry out the generation of the behavioral information accordingly.
  • This information for example, from a driver assistance system of the emergency vehicle, such as a navigation system or lane departure warning system (LDW system) (LDW system) (lane departure warning system), which system detects the lane and can also be determined over which lane is being used by the emergency vehicle , generated and transmitted to the own motor vehicle.
  • LDW system lane departure warning system
  • the control device is communicatively connected to a driver assistance system integrated on the vehicle side, in particular a navigation system, and designed to determine the behavioral information as a function of the position and / or lane data of the own vehicle determined by the driver assistance system, in particular the navigation system.
  • a driver assistance system any system can be used that provides appropriate data, such as an integrated navigation system or a lane detection system (LDW system).
  • DGP differential global positioning
  • An expedient development of the invention provides that signals transmitted via the receiving device and also from other vehicles containing signal information about or relating to the respective vehicle receivable are, wherein the control device is designed to generate the behavior information in response to this signal information.
  • a plurality of vehicles equipped with the same suit communicate with one another and exchange data, that is, they balance the corresponding information with one another and can react with one another. If, for example, it results that other vehicles equipped with a corresponding transceiver device, which drive behind their own vehicle and are relatively closer to the approaching emergency vehicle, have determined as behavioral information that the driver deliberately escapes to the left, this information is also correct for the own motor vehicle of benefit, as an appropriate adjustment can be made and the behavior recommendation also indicates a dodge to the left.
  • the situation may be slightly different again, here, depending on the vehicle's own position, it can be recognized via the comparison that, for example, two vehicles traveling directly behind the own vehicle have moved to the left, and thus possibly the intersection area has already been adequately occupied so that it could come to a blockage in a left to the left by your own motor vehicle.
  • the control device can recognize this and then output a correspondingly differently designed behavioral information due to the adjustment.
  • the invention relates to a method for the guidance of a motor vehicle when approaching a right of way authorized emergency vehicle.
  • This method is characterized in that the emergency vehicle continuously or intermittently sends a signal containing signal information indicating the emergency vehicle itself and its direction of travel via a transmitting device, which receive signal from a motor vehicle located in the receiving area via a receiving device and an associated control device is processed to generate and output a behavior information to the driver in response to the signal information.
  • the behavior information preferably contains information about the route to be selected directly, in particular for forming a driving lane for the emergency vehicle, thus indicating in which direction the driver should avoid or continue, or how he generally has to behave and react.
  • the signal information of the emergency vehicle may also contain information about the future driving route of the emergency vehicle, which is taken into account by the control device for generating the behavioral information, as the signal information may also contain information about the desired, future driven lane. All signal information relating to position or lane data is preferably determined by a corresponding driver assistance system of the emergency vehicle and the signal information is impressed on the transmitted signal.
  • the control device itself communicates expediently with a vehicle-integrated driver assistance system, in particular a navigation system, and determines the behavioral information as a function of the position and / or lane data determined by the driver assistance system.
  • a car-to-car communication with other motor vehicles having corresponding combined transmitting and receiving devices preferably also takes place via WLAN communication means, so that the vehicles can exchange corresponding data with one another, which is expedient for generating the behavior information are.
  • the range of the transmitting and receiving devices is in particular in the known WLAN technology in the range between 300 - 500 m, so that a sufficiently early, but not too early warning possibility or information generation is possible.
  • any car-to-car communication such as a multi-hop method may be used.
  • An expedient development of the invention provides that the emergency vehicle communicates with a central control center, from which information concerning the target to be approached by the emergency vehicle containing target position information is transmitted, depending on which a driver assistance system integrated in the emergency vehicle, in particular a navigation system automatically switched on.
  • the driver of the emergency vehicle is therefore relieved of programming the destination, for example, in the navigation system. Rather, this happens automatically via a corresponding communication between the driver assistance system of the emergency vehicle and a control center.
  • the latter In the presence of a travel command, the latter automatically sends a corresponding signal to the emergency vehicle via which the driver assistance system is immediately switched on and is automatically programmed, at least with regard to the target position.
  • corresponding position or lane data are continuously recorded by the driver assistance system, which can then be transmitted as signal information to the surrounding road users, so they are equipped with a corresponding transmitting and receiving device together with control device.
  • Fig. 1 shows in the form of a schematic representation of an inventive motor vehicle 1, comprising a transmitting and receiving device 2, which is designed for wireless signal transmission or wireless signal reception, in particular in WLAN technology.
  • a control device 3 which processes received signals or their signal information or processes any signals or signal information to be transmitted and controls the transmission and reception operation of the transmitting and receiving device 2.
  • a device 4 for the optical output of a behavioral information determined by the control device 3, as well as a device 5 for the acoustic output of the behavioral information, either one or the other device 4, 5 or both may be present.

  • the signal given by the control station 13 furthermore contains precise information about the destination, so that automatic programming of the navigation system 12 takes place via the control station signal. The driver of the emergency vehicle 7 therefore does not have to program independently.
  • a driving route is now automatically determined, thus corresponding routes or route data, which are also known to the control device 11 and transmitted together with corresponding actual position data, which are determined continuously via the navigation system 12, via the transmitting and receiving device 10 can.
  • the transmitted signal thus contains the signal information generally indicating the presence of an emergency vehicle in the transmission area, as well as signal information about the actual position of the emergency vehicle and the intended route, as well as possibly on the intended lane that wants to take the vehicle, if this information, for example via the Navigation system or another driver assistance system can be determined.

  • the transmitted signal of the emergency vehicle 7 further includes direction information. From this results for the control device 3, whether the emergency vehicle accommodates, therefore, therefore, a reaction of all probability is not required, or if the emergency vehicle, for example, approaches from behind or - in connection with the position information - already in front of the own motor vehicle.
  • the own actual position is known from the navigation system 6, so that it can be easily determined how the relative position between own motor vehicle 1 and emergency vehicle 7 is.
  • the control device 3 now determines a behavioral information that is output to the driver either at the device 4 and / or the device 5.
  • this behavior information may only indicate that an emergency vehicle is nearby, but a response is not required. However, if a reaction is required, a behavioral recommendation may be issued, such that, for example, the vehicle should travel to the left or right of the lane to clear a lane, etc.
