Definitions

  • the invention relates to a beacon transmitter on a driveway according to the preamble of the main claim.
  • a beacon transmitter is already known from 'procedings of the DRIVE conference, 4th - 6.2.1991, advanced telematics in road transport' (pages 248 to 268), which performs a data exchange with a vehicle receiver (on-board unit, OBU) carries out the semi-passive transponder method.
  • OBU on-board unit
  • a communication zone on a lane is illuminated, which is relatively small in order not to influence adjacent lanes and vehicles located thereon. Due to the relatively small area available, there may be a complete data exchange between the beacon transmitter and the OBU, especially when the vehicle is traveling at high speed. This can lead to the information transmitted being incomplete or incorrect.
  • the beacon transmitter according to the invention with the characterizing features of the main claim has the advantage that the wake-up zone activates the vehicle receiver in time so that there is sufficient time for complete data transmission even at high vehicle speed.
  • the measures listed in the dependent claims permit advantageous further developments and improvements of the beacon transmitter specified in the main claim. It is particularly advantageous that the wake-up signal is transmitted independently of the main antenna by a separate wake-up antenna or parts of a main antenna. Problems with interfering interference, such as can occur when two antennas are used simultaneously, are thus avoided, since only one antenna is active at a time.
  • a suitable switch for example a micro
  • the beacon transmitter can alternatively be switched to the wake-up antenna or the main antenna using wave switches with PIN diodes.
  • the wake-up antenna can also be directed so that it covers several lanes, if this application can be approved.
  • a particularly simple design of the wake-up zone is also achieved in that the directional characteristic of the main antenna is controlled by controlling the phase and / or amplitude assignment. Such control of the phase and amplitude direction can be achieved by controlling the individual elements of an array antenna. The respective weighting is switched over synchronously with the transmission of the wake-up signals.
  • a particularly simple control results from the fact that the wake-up signal is emitted in constant or variable time segments.
  • the time segments can be selected so that the vehicle device is still safely activated even at high speed of a vehicle.
  • beacon transmitter and the vehicle device is provided in the microwave range, these devices working according to the semi-passive transponder method.
  • Figure 1 shows an embodiment
  • FIG. 1 shows a beacon transmitter 1 which is attached, for example, on a gantry bridge or at a traffic light on a route 7.
  • the beacon transmitter 1 operates, for example, in the microwave range at 5.8 GHz using the semi-passive transponder method.
  • This transmission method is known per se from, for example, "procedings of the DRIVE conference", Brussels, February 4 - 6, 1991, 'advanced telematics in road transport', pages 248 to 269 (volume 1) therefore need not be explained in more detail.
  • the beacon transmitter according to the invention has an antenna 3 and a wake-up antenna 2, which are alternatively activated via a changeover switch 4.
  • the wake-up antenna 2 is spatially directed towards the route 7 with its lane such that an arriving motor vehicle 5 first drives through the wake-up zone A before it enters the communication zone B of the main antenna 3.
  • parts of the main antenna which are preferably used as an array, can also be designed as a wake-up antenna.
  • the main antenna is changed by controlling the directional characteristic in such a way that the directional characteristic is changed by weighting the phases and amplitudes of the individual elements.
  • a microwave switch which has PIN diodes or similar high-frequency switches, is preferably provided as the changeover switch 4.
  • the wake-up antenna can be designed such that several or all lanes are covered.
  • a second main antenna could also be used as a wake-up antenna. This could e.g. B. then be of importance if the wake-up area must be illuminated in a similarly defined manner as the communication area. For this purpose, a change 'of the alignment of the antenna is required to provide the desired advancement to reach the Aufweck formeres.
  • the motor vehicle 5 has a vehicle receiver 6 (OBU, on-board unit) which preferably works according to the semi-passive transponder method and can connect to the beacon transmitter 1.
  • the transponder can be equipped with a battery which supplies the necessary current for operating the device and for further assemblies.
  • memory modules can be buffered with the battery so that they do not lose their information. Such memories are used, for example, for debiting road user fees from a fee card.
  • the vehicle device 6 is switched to an inactive state, the sleep mode, most of the time. When approaching a beacon, it is now activated by the wake-up signal of the corner antenna 2 and thereby switched to the operating mode.
  • the wake Circuit which is activated by the signal of the wake-up antenna 2, however, has a very low quiescent current, so that its power consumption does not place a heavy load on the battery.
  • the transition time from sleep mode to operative mode is chosen to be as short as possible. If the vehicle subsequently arrives in communication zone B, the actual data exchange, for example traffic information or directions of travel, can take place. If this communication area is not sufficient for the transmission of the information, then the entire amount of information can be divided into different communication areas that follow one after the other. The information is then transmitted partially.

Abstract

Balise émettrice pour la communication avec un récepteur embarqué sur un véhicule, dans laquelle il est prévu, grâce à des moyens appropriés, par exemple, une antenne supplémentaire d'activation, de former une zone d'activation disposée en avant de la zone de communication. Dans la zone d'activation, l'appareil embarqué est activé de telle façon que l'échange de données s'effectue dans la zone de communication subséquente, entre la balise émettrice et l'appareil embarqué. Dans le cas où un grand nombre de données doivent être transmises, la zone d'activation ou d'autres zones de communication sont également disponibles, de sorte que la transmission de données s'effectue partiellement. Des éléments de l'antenne principale peuvent être utilisés comme antenne d'activation grâce à un système de commande approprié.
