Definitions

  • the invention relates to a system for transmitting information between vehicles on multi-lane roads and fixed transmitting and receiving devices, each lane being assigned a detector arrangement for detecting all passing vehicles, and a destination transmitter is also provided in at least some of the vehicles to send out a destination address entered in the vehicle according to a call signal from the respective fixed transmitting device, and the destination addresses can be recorded and evaluated by the respective fixed receiving device.
  • the data exchange between the vehicle and the fixed device takes place in each case via induction loops which are arranged in the individual lanes.
  • the individual vehicles are first detected by induction measurement; a call impulse is then sent to each recognized vehicle. If the vehicle is equipped with a route guidance device, it sends its destination address and then again receives information associated with this destination address via the loop.
  • the object of the invention is to design a system for information transmission of the type mentioned in such a way that, without the costly installation of induction loops, the passing vehicles are detected with as little means as possible by passive detection and vehicles equipped with destination transmitters are queried for their destination address can.
  • this object is achieved in that detectors are used in each case for vehicle detection, which emit a detection signal and evaluate its reflection, and in that the detection signal also serves as a call signal for the destination transmitter in the respective vehicle, the detectors assigned to one another being controlled in this way via a synchronization device are that they send out their detection signals cyclically in sequence.
  • the system according to the invention therefore uses active detectors for passive detection of the vehicles, the transmitters and receivers of which can be arranged, for example, above the roadway. Since the detection signal is simultaneously used to trigger the destination transmitter in the vehicles, no separate transmitter is required in the stationary device for the destination query.
  • Microwave, ultrasound or infrared can be used for passive detection, whereby a combination of pulse methods (for vehicle counting and vehicle type differentiation) and Doppler methods (for determining the speed) is possible.
  • the detection area must be limited and adjustable so that the traffic flows can be resolved into individual vehicles and detected separately according to lanes.
  • Microwave or infrared radiation can be used to actively transmit the destination addresses from the vehicles. These two transmission media can penetrate the windshield of a vehicle. Ultrasound could also be used; but in this case the transducer would have to be installed in such a way that it can radiate directly into the open.
  • the vehicle-side destination transmitter is expediently set such that it transmits its information direction narrow narrow abstranit, so that they do not mix with those of preceding or following vehicles. Transversely to the direction of travel, the transmission can take place in a wide range, so that the fixed receivers are mounted relatively freely and do not have to be set too precisely. This is possible thanks to the cyclical coordination of the detection signals of adjacent lanes.
  • the devices for vehicle detection and destination query can continue to be combined with stationary transmission devices and vehicle-side reception devices for transmitting guidance recommendations. It is expedient for the fixed transmitters to transmit the guidance recommendations in a relatively wide range, so that the vehicles are in their transmission range for a sufficiently long time.
  • FIG. 1 schematically shows vehicles FZ1, FZ2 and FZ3 which move on a roadway FB with several lanes.
  • Fixed devices are arranged above the carriageway, namely detectors D and receivers ZE for destination addresses emitted by the vehicles.
  • a guidance information transmitter LS which broadcasts guidance recommendations to all passing vehicles.
  • this control information transmitter LS does not necessarily have to match the whose facilities are coupled.
  • the detectors D each contain, for example, a microwave transmitter and a receiver; however, they can also work with ultrasound or with infrared radiation. They each send out a narrowly bundled detection signal a in order to detect each passing vehicle in the corresponding lane.
  • the vehicle is equipped with a vehicle device FG for route guidance, this is prompted to transmit the destination address b entered in the vehicle, for example the vehicle device FG1 in the vehicle FZ1.
  • This destination address is received by the stationary receiver ZE and forwarded to a central office for evaluation.
  • Fig. 2 shows the arrangement of the fixed devices across the road.
  • a lane with three lanes is assumed, the vehicles FZ1, FZ2 and FZ3 driving in lanes lying next to one another.
  • the cockpit of the individual vehicles is shown schematically.
  • Each lane is assigned a detector D1, D2 or D3, which narrowly bundles the detector signal a1, a2 or a3 only in its associated lane.
  • these detection signals also have the purpose of querying the destination addresses entered in vehicle devices FG1 etc.
  • the vehicle devices FG1, FG2 and FG3 are triggered by the detection signals a, whereby these detection signals a1, a2, a3 etc. are each transmitted cyclically in order. Ent speaking, the vehicle devices also respond cyclically in sequence.
  • the control information transmitters LS according to FIG. 1 transmit their information in a wide range so that the vehicles are in their transmission range for a sufficiently long time.
  • the time sequence of the information transmission according to FIG. 1 is such that the vehicle first enters the transmission area of the guidance information transmitter LS and receives the guidance information c. As soon as the vehicle then arrives in the beam a of the detector D, it is detected and, at the same time, asked to give its destination address. Finally, the destination address b is finally emitted from the vehicle to the receiver ZE.
  • FIG. 3 The function of the system according to the invention will now be explained using a block diagram according to FIG. 3.
  • three vehicles FZ1, FZ2 and FZ3, each with a vehicle device FG1, FG2 and FG3, are assumed, which move in different lanes.
  • Each vehicle device has a receiver FE and a travel destination transmitter ZS, in which the destination address is entered, for example, by hand.
  • Each lane is assigned a detector D1, D2 or D3, each with a transmitter DS and a receiver DE.
  • the individual detector transmitters DS1 ... DS3 are controlled via a synchronization device SYN in such a way that they cyclically emit their detection signal in the form of microwaves, infrared radiation or ultrasound. If these detection signals strike a vehicle, this is recognized by the detector receivers DE1 ... DE3 and, for example, supplied to a counter Z. The meter reading can then be transmitted to a control center LZ for further evaluation.
  • the detection signal is received in the receiver FE and passed on as a call signal to the vehicle transmitter FS.
  • the vehicle transmitter then emits its entered destination address, which is received by the fixed receiver ZE.
  • These coded destination addresses are also fed to the control center LZ.
  • control center LZ can be radiated guidance information about the Leitinformationssender LS, which are then received in the individual vehicle receivers FE and selected, but this is not the subject of this application.
