Definitions

  • the invention is based on a route guidance system for vehicles according to the preamble of the main claim.
  • a traffic guidance system has already become known which works with built-in road loops. If a vehicle drives over such road loops, messages are transmitted between the vehicle and a switching center which, after the destination has been named, the vehicle driver automatically receives important information such as direction instructions, road conditions, favorable speed, etc. on a display panel.
  • Such traffic guidance systems are furthermore in the European patent application 79 100 732.1, in Radio Mentor Electronics, volume 44, number 3, 1978, Berlin, page 103 to page 108 "ALI system for route guidance and traffic data acquisition" and in the NTZ, volume 28 number 8, 1975, pages 306 to 308 "Electronic Signpost for Motorists".
  • Computer-controlled telephone systems are also known, which are manufactured by Bosch, for example, under the name OF4D. These computer-controlled telephone systems have a transmitter and a receiver that enable radio transmission to a relay station. The signals are usually transmitted in the FM range.
  • OF4D Computer-controlled telephone systems
  • these known telephone arrangements are very complex and also unreliable since, on the one hand, there must be a high outlay for the security of the transmission and, on the other hand, only a few frequency ranges are available, so that the telephone subscriber often does not find a free channel.
  • Another disadvantage of computer-controlled radio telephones is that the security against eavesdropping is not ensured.
  • the route guidance system according to the invention with the characterizing features of the main claim has the advantage that, on the one hand, existing facilities of the route guidance system can be used and, on the other hand, the number of channels for conducting the call can be adapted to the requirements at any time. Another advantage is that such car phones are inexpensive to manufacture, so that in conjunction with the large number of channels, the telephone system can be widely used. The system also has the advantage that unauthorized eavesdropping on calls is hardly possible.
  • pulse code modulation it is still possible to accept the channels intended for the route guidance data unchanged, since in this case the voice transmission is also carried out digitally.
  • the transmission between the vehicle device and the street device takes place word for word alternately in both directions. Since the transmission is digital, it is particularly advantageous that the data transmission modules provided for the route guidance system are used for this purpose.
  • the auxiliary frequencies for the transmitter and the receiver are expediently derived from the cycle of the route guidance system.
  • the telephone transmission can then be formed particularly easily if one channel each is used for the back and forth speech is used.
  • the signals for the back and forth are split by means of hybrid circuits in the loop device.
  • the dialing and auxiliary pulses are expediently transmitted as a digital signal via the channels of the route guidance system. This means that the existing facilities can continue to be used without any changes. Another option is to transmit the dialing and auxiliary impulses via sound frequencies in the voice channel. This type of transmission requires little effort when processing the pulses.
  • a code of the vehicle device is requested before the telephone connection is set up. Simple monitoring of charges is possible if the charges are temporarily stored in the loop device with a key or code number and can be called up there by the switching center, or if there are modules in the on-board device in which the charges can be debited due to charge impulses.
  • the vehicle device which is designed for traffic route guidance, also for telephone traffic, it is only necessary to provide a further transmitter and a further receiver, to which it is switched during voice transmission.
  • These transmitters and receivers are controlled by auxiliary frequencies which are obtained from the clock of the information system.
  • the further transmitter and receiver advantageously work with amplitude or frequency modulation. This is the cheapest way to expand the device.
  • the microcomputer is favorable to use the microcomputer as a telephone number memory and number repeater. It is also favorable to connect the route guidance system according to the invention to a euro signal receiver. This results in the advantage that the vehicle driver can always be reached via the euro signal and can call an agreed-upon position when there is a signal using the telephone according to the invention.
  • FIG. 1 shows a first embodiment of a telephone according to the invention
  • FIG. 2 shows an exemplary embodiment of a control device located on the street, which is suitable for telephone transmission
  • FIG. 3 shows a second exemplary embodiment of a vehicle telephone according to the invention
  • FIG. 4 shows another example of a control device located on the street, which is suitable for telephone transmission.
  • induction loops are embedded in the street. These induction loops are located directly on the street or in parking lots and motorway entrances.
  • the induction loops are each connected to a process computer, which in turn is connected to a central computing device via data lines. This makes it possible to optimize traffic flow by influencing traffic using traffic data acquisition.
  • the contact with the driver takes place via a car device, to which messages are transmitted via the induction loop.
  • the information is given in two directions. Before starting, the driver must enter his destination in the vehicle device in the form of a decimal number. When driving over an induction loop, the vehicle device is activated and this data is transmitted to the process computer. The computer then determines individually how the driver of the vehicle hits its special destination on the shortest route in time.
  • the principle of interactive transmission is based on the fact that a vehicle equipped with a transmitter, receiver, destination keypad and optical display panel as well as a special antenna reports presence and destination request when entering the system area.
  • the information is recorded in an induction loop and first passed on to a street device. From the memory of the microcomputer in the road device, the directional recommendations given for the vehicle's specific destination are taken and transferred back into the vehicle via the same induction loop.
  • the direction recommendations also include speed recommendations as well as messages about the risk of traffic jams, fog and slippage. Details of the specific structure of the vehicle devices as well as the road loops and the computing devices can be found in the BMFT report "Field testing of a route guidance and information system for drivers (ALI)" in addition to the publications already mentioned.

  • the transmitter 24, the receiver 25 and the clock processor 31 are required.
  • the transmitter 24 and the receiver 25 are connected to a hybrid circuit 26.
  • the hybrid circuit causes the splitting into the back and forth channel required for the two-way communication and is well known from telephone technology.
  • the dialing device 27 is still required for connection to the telephone line.
  • the generation of the dialing pulses is carried out by the microcomputer 20 of the loop device, which is connected to the dialing device via the control bus 28 and the data bus 29.
  • a telephone connection now has the following sequence: If the driver intends to make a phone call, he drives to the next parking lot, which has a corresponding telephone loop. If the vehicle has come to a standstill, which is recognized by the travel sensor 6, the microcomputer 20 of the loop device transmits call steps via the transceiver 22 and the loop 23, as is the case with the normal traffic information system. The However, the number of call steps can be greatly reduced compared to the traffic information system. Approximately one call step per second is sufficient. If the driver is in a marked loop position and his vehicle has come to a standstill, he picks up the telephone receiver 14 of the vehicle device, which in turn is connected to the transmitter 8 and the receiver 7.
  • the microcomputer 1 of the vehicle device now responds to the next call step of the loop device with a data telegram, as is known from the traffic information transmission. Only the keyword, for example in byte 1 of the telegram, has changed.
