SE465189B - Method of providing traffic information to a driver and/or passengers in a vehicle and arrangement for implementing the method - Google Patents

Abstract

The invention relates to a method of automatically providing continuous traffic information to a driver and/or passengers in a vehicle, in which each stop has fixed equipment with a position indicator containing a unique code which provides information relating to the position of the vehicle along a traffic route, and an arrangement on the vehicle for receiving the information from the position indicator. <IMAGE>

Description

465 189 A further wish would be to obtain good statistics on the number of boardings at different stops at different times and on different days, in order to be able to better control traffic.

An advantage would be if shops and companies were allowed to provide information and / or advertising about their activities to the passengers in a means of transport just when this passes the place where the company or shop is located. And you want all this without the driver of the vehicle having to be involved in any new task.

With regard to information to passengers about the next stop, this cannot be done today without the involvement of the driver of the vehicle. There is no fully automatic information system today.

An object of the present invention is to give the passengers in a transport vehicle information about the next stop well in advance of the stop, without the manual participation of the driver. This can be done both with synthetic speech and visually via a display.

Another object of the invention is to give the traffic control an indication of where the vehicle is on its route and how much one is late. It is also possible with the present invention to obtain a passenger bill which is then time and place determined. It then facilitates the insertion of extras on the line. In addition, you can get a ticket check on the vehicle. You can then get a ticket machine for zoning and time division for a fee.

A further object of the invention is to provide additional information or advertising from companies or 3,465,189 shops located along the mileage of the vehicle. You can make the passengers look in the direction where they are and tell about their business or show their advertising.

The application of the taxi system would divide a city into different zones and you would then be able to call directly from the command center the vehicle that is closest to the place you want. This can also be applied by authorities e.g. the police.

The characteristics of the present invention appear from the following claims.

The present invention will now be described in more detail with reference to the accompanying drawings, which show a preferred embodiment, in which Figure 1 shows a block diagram of the actual method of automatically providing traffic information in, for example, public transport for a bus. Figure 2 shows the application clearly for a traffic vehicle, and figure 3 shows the device itself for carrying out the method of providing automatic traffic information and then the position sensor. Figure 4 shows the device in the vehicle. Figure 5 shows the device in its entirety.

The method according to the invention shown in the block diagram in Figure 1 works so that at each stop there is a fixed equipment 30 with position indicators with a unique code which provides information about its position along a traffic line and / or an area of a vehicle 31 passing over and then picks up this information via its equipment, after which the following automatic functions are obtained: 465 189 4 1. Stop display on display 32. 2. Stop call with digitized sound. 3. Display of destination and line number interior and exterior. 4. Display of advertising and / or information on display 33 controlled by the position sensors. 5. Control of ticket machine for zoning and time division of fee. 6. Passenger count, zoned and time-bound, for statistics. 7. Indication of position from vehicle to traffic control center with radio communication or over the telephone network. 8. Prioritization of buses and emergency vehicles at traffic-controlled traffic intersections.

Figure 1 also shows a receiving antenna 34, a transmitting antenna 35 and a tachogenerator 36 as well as a terminal 37.

Figure 2 shows a traffic line for, for example, a bus and where you see the different stops 38 with the different position sensors 39.

It is also seen how a control center 40 can follow the vehicle 41 on its way along the line. An information system 42 is also shown.

Figure 3 shows a diagram of both transmitter and receiver part in the position sensor and in the receiver part consisting of an antenna loop 1 for reception or transmission as well as an amplifier 2, a bandpass filter 3 and further a detector 4 with time-off and a unit 5 for connection of the transmitter part.

Furthermore, in Fig. 3 one can find a transmitter part consisting of a code switch 6 and a pulse generator 7 as well as a frequency shift generator 8 and a power amplifier 9. A transmitter part 10 and a battery charger 11 also come to the transmitter part m

Figure 4 shows the device for the vehicle and then an antenna 12 which first transmits a signal. When the position sensor transmits its code via the antenna loop 1, a signal containing the position sensor code is induced in the antenna 12. This signal is amplified in the amplifier 13 and filtered in the bandpass filter 14. In the phase lock detector 15, the frequency shift is detected. The detected pulse telegram is decoded in a decoder 16, after which the code is transmitted to the CPU unit 17, which is the brain of the control unit / computer. Other functions are connected to this unit via the I / O unit 19 or directly to the CPU unit 17. You can see the transmitter part 20 of the vehicle which transmits frequencies via the antenna 12. Furthermore, you can see in the figure a tachogenerator 21 which is used for to provide information about the movement of the vehicle and the distance traveled. An internal terminal 18 is connected to the equipment to provide communication between humans and equipment. You can also see the various functions stop display 22, a speaker 23, an advertising display 24 and a ticket machine 26. You can also see a unit 27 for passenger counting and a unit 28 for communicating with a control center.

Figure 5 shows the device mounted on a vehicle and where this vehicle moves to a stop with a fixed position sensor. Ante: The loop 1 receives a signal from a transmitter 12 placed on the vehicle. The transmitted signal influences the position sensor to give a unique signal, which is then picked up by the receiver in the bus. Thereafter, a signal will automatically give a message via the bus 465 1896 via a display ll about the next stop. Further in Figure 5 you can see an internal terminal 18 and the bus's CPU 17.

The drawings have shown only one embodiment of the invention, but we must point out that it can be designed in many different ways.

The system automatically provides information to the driver and / or passenger of a vehicle about its position along a line or in an area. For example, automatic information is given about the next stop in a vehicle.

A control unit / computer located in the vehicle receives information about the vehicle's location along the entire traffic line. A position sensor at each stop sends a code to a receiver. You can then use inductive, microwave, radio, infrared, laser, radar or ultrasonic transmission. The control unit / computer decodes the position and shows the name of the next stop on a display and provides information with programmed digitized sound via the vehicle's internal communication system. The CPU unit has the capacity to store data for later processing in other computer systems for statistics etc. mentioned. For the position sensors, codes or information for many different lines can be stored and left depending on unique signals from passing vehicles.
