Abstract

PURPOSE:To properly guide an approaching vehicle to a prescribed lane in accordance with the state of a fare station or the like by providing this vehicle guiding device with an information processing means for generating vehicle guide information to a prescribed position and a transmitting means for displaying the information to a vehicle. CONSTITUTION:A radio card 1 to be a portable information recording medium arranged on a prescribed position in a vehicle is visually arranged on a dashboard e.g. of the vehicle, receives wave signals of an intermediate frequency or the like transmitted from a transmission processor 2 by a receiving part 12, and after executing necessary processing, displays data necessary for the vehicle on a display part 16. The processor 2 arranged in the vicinity of a road before the fare station detects whether the approaching vehicle is equipped with the card 1 or not and transmits information for guiding the vehicle to a prescribed lane in the fare station from a transmission part 23 through radio waves. The processor 2 detects the congestion of respective lanes in the fare station by a congestion detector 24 and distributes respective approaching vehicles to respective lanes in accordance with the congestion state.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle guidance system for guiding an approaching vehicle to a predetermined lane at a tollgate on a toll road, for example.

[0002]

2. Description of the Related Art Toll roads such as expressways require the collection of tolls. At present, in each lane of the toll gate, an attendant stops the vehicles entering one by one and distributes the pass ticket indicating the entry position, and the fee is calculated by the pass ticket of the vehicle leaving one side, and the fee is collected. ..

In addition, the Dallas North Trullway and the Greater New Orleans Bridge (GREATER) in the United States
In NEW-ORLEANS BRIDGE), a user purchases a data carrier called a tag that can write / read data by microwaves, attaches the tag inside the windshield of the vehicle, and travels on the road. At the entrance / exit toll gate, the read / write processing device installed in the toll gate accesses the tag inside the vehicle by microwave, and the unique number of the tag is identified, and at the same time, the toll when passing through the road is calculated. This toll is deducted from the tag user's bank account, for example.

[0004]

Depending on the toll gate, there may be a lane without a read / write processing device even if it has a plurality of lanes. If the vehicle of the tag user travels through a lane not equipped with such a read / write device, there is a problem that the toll cannot be collected.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a vehicle guide device capable of properly guiding an approaching vehicle to a predetermined lane in accordance with the state of a tollgate or the like.

[0006]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides an information processing means for generating information for guiding a vehicle to a predetermined position, and the information from the information processing means to the vehicle. And transmitting means for displaying.

[0007]

The vehicle guiding device of the present invention constantly transmits information for guiding the vehicle to a predetermined lane from the transmitting means installed along the road in front of the tollgate. A portable information storage medium such as a wireless card mounted on the approaching vehicle receives this information,
It is displayed on the display means on the medium. The driver of the vehicle drives the vehicle so as to pass through a predetermined lane according to the displayed information.

[0008]

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of a vehicle guiding device of the present invention. This vehicle guidance device is composed of a wireless card 1 which is a portable information storage medium placed at a predetermined position in the vehicle, and a transmission processing device 2 which is placed near the road in front of the toll booth. Wireless card 1 is CP
U11, receiver 12, demodulator 13, data memory 14,
The display control unit 15, the display unit 16, and the DC power supply 17 are included. The wireless card 1 receives a radio wave signal such as a medium wave or a microwave from the transmission processing device 2 at the receiving unit 12, performs a necessary process, and then causes the display unit 16 to display data necessary for the vehicle. The CPU 11 has a read / write processing function. The wireless card 1 is visibly arranged on a dashboard of a vehicle, for example. The transmission processing device 2 includes an information processing unit 21, a modulation unit 22, a transmission unit 23, a traffic jam detector 24, a ROM 25, a RAM 26, and a power supply 27. The transmission processing device 2 detects whether or not the approaching vehicle is a vehicle equipped with the wireless card 1, and transmits information for guiding the vehicle to a predetermined lane at the tollgate from the transmission unit 23 by radio waves. In addition, the transmission processing device 2 also allocates the approaching vehicle to each lane in accordance with the traffic jam condition of each lane at the tollgate.

FIG. 2 is a perspective view showing the external appearance of the wireless card 1 shown in FIG. The display section 16 displays lane information that the approaching vehicle should pass through.

FIG. 3 is a top view illustrating the arrangement of the transmission processing device 2 of FIG. 1 near the toll gate lane. A wireless card 1 is mounted on a vehicle 3 that enters the tollgate. A transmission unit 23, which is a transmission antenna, is installed at a distance of 100 to 200 m before the lane entrance of the tollgate, and constantly transmits lane guidance data to the vehicle 3. The traffic jam detector 24 is installed above each lane in front of the toll booth to detect the congestion of vehicles in each lane and transmit the information to the information processing section 21. In the tollgate shown in FIG. 3, the lanes with lane numbers 1 and 2 are provided with the read / write processing device 30, and the lanes with lane numbers 3 and 4 are not provided. Although not shown, the information processing unit 21, the modulation unit 22 and the like of the transmission processing device 2 are arranged near the toll gate lane.

Next, the operation of the vehicle guidance system of the present invention will be described with reference to FIG.
This will be described with reference to the flowchart in FIG.

The transmission section 23 at the entrance of the toll gate constantly emits lane guidance radio waves to the vehicle 3 equipped with the wireless card (S
T1). Vehicle 3 enters the toll gate entrance and wireless card 1
The receiving unit 12 receives the lane guidance radio wave (ST2).
The received lane guidance information is demodulated by the demodulation unit 12 and sent to the CPU 11. The CPU 11 displays the demodulated lane information on the display unit 16 (ST3). For example, in FIG.
As shown in, the lane information "Lane No. 1 shift to the left" is displayed. The driver of the vehicle visually recognizes the lane information on the display unit 16 and moves the vehicle into the lane in which the wireless card processing device, for example, the read / write processing device 30 is installed (ST4). When the congestion detector 24 detects that the tollgate is congested and the vehicles are concentrated in a specific lane, the transmission unit 23 transmits information for guiding the vehicle to a lane with few vehicles. You can also It is also possible to transmit the lane guidance information from the transmission unit 23 by a manual operation.

FIG. 5 is a block diagram showing another embodiment of the wireless card. This wireless card 1a has a voice generator 18
Is provided, and the lane guidance information is displayed on the display unit 16 and is also guided by voice by the voice generation unit 18. As a result, it is possible to reliably guide the vehicle.

[0015]

As described above, according to the present invention,
According to the state of each tollgate such as the presence or absence of the read / write processing device and the condition of each lane, the vehicle entering the tollgate can be accurately guided using a wireless card.
