Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is installed on a road,
Operation consisting of a roadside transmitter that transmits information on traffic rules to be implemented at the installation point by an airborne signal, and an in-vehicle device that is mounted on a vehicle and receives and processes information transmitted from the roadside transmitter Condition monitoring system,
Also, the present invention relates to a roadside transmitter and an in-vehicle device used in the system.

[0002]

Since the driving of a vehicle is basically carried out based on the will of the human being, whether or not to obey the traffic rules and the manners of traffic depends on the individual driver. I am trying. Especially in a place where there is no other person's eyes. However, unilaterally expecting such an individual's consciousness does not really help.

Most people tend to have a feeling that "no one has seen this" or "this degree will be all right", and driving based on such feeling will eventually cause an accident. Will be connected to. Therefore, as one of the measures to make the prevention of traffic accidents more effective,
For example, it is possible to introduce a system for monitoring the driving state of each vehicle.

The present invention has been made in view of the above circumstances, and an object thereof is to monitor a driving state of each vehicle to more reliably prevent a traffic accident from occurring, Another object of the present invention is to provide a roadside transmitter and a vehicle-mounted device used in the system.

[0005]

According to the driving state monitoring system of the first aspect, the roadside transmitter transmits information on traffic rules to be enforced at an installation point on the road by an airborne signal. Then, when the vehicle-mounted device receives the information transmitted from the roadside transmitter in the reception area centered on the installation point, the violation determination means acquires the information and the driving information acquisition means at the time when the information is received. When it is determined that the driving of the vehicle violates the traffic rules to be enforced at the installation point by comparing the information with the information, the information about the violation is processed so that it can be used by an outside person or an institution.

That is, the system of the present invention can monitor the driving condition of the vehicle, and when traffic rules are violated, concrete evidence can be left. And
If the information is used by the authorities, it is possible to detect traffic violations without fail, so that the person who drives the vehicle has to raise awareness that he / she must comply with traffic regulations. Therefore, the traffic manners of the driver can be reliably improved, and the occurrence of traffic accidents can be reliably suppressed.

According to the operating state monitoring system of the second aspect, the vehicle-mounted device transmits the information determined by the violation determining means to the outside via the air propagation signal. Therefore, for example, the authority receives the information. Then, the driving state of each driver can be grasped in almost real time. If the traffic violation points are deducted based on the recorded information, the violation can be detected fairly.

According to the driving state monitoring system of the third aspect, when the vehicle-mounted device receives the information transmitted by the vehicle-mounted device of the vehicle located in front of the vehicle-mounted device, the occupant of the vehicle receives the information based on the content of the information. The warning means. That is, when the vehicle traveling in front has a high vehicle height and a wide vehicle width such as a large truck, the vehicle located behind the vehicle may not be able to fully grasp the condition on the road ahead.

In such a case, for example, if a vehicle in front of the vehicle ignores the signal and enters the intersection, a vehicle in the rear may subsequently enter the intersection, which is dangerous. Therefore, if the information about the violation of the vehicle ahead is transmitted to the vehicle behind to warn the driver, the driver of the vehicle behind can stay at the intersection.

According to the operating state monitoring system of the fourth aspect, the vehicle-mounted device records the information determined by the violation determining means in the recording medium, so that the violation information recorded in the recording medium is read out if necessary. It can be used for various evaluations.

For example, if each driver has his own recording medium and one driver uses the recording medium assigned to himself / herself when he / she drives a plurality of vehicles, the respective recording media can be used. Since information is recorded when a violation occurs in driving performed in a vehicle, it is possible to record a history of the violation for each driver.

According to the operating condition monitoring system of the fifth aspect, the vehicle-mounted device performs the security processing so that only the specially authorized person can read the information stored in the recording medium. That is, since the violation information is information relating to the privacy of an individual, it is not desirable that any person can easily read it. Therefore, for example, by performing a security process that makes it possible to read out information by entering a specific password, PIN, or encryption key, only specially authorized persons can read out violation information. Become.

According to the operating state monitoring system of the sixth aspect, the on-vehicle device individually manages the recording medium based on the personal information and records the information corresponding to the individual. Based on this, it is possible to decide whether or not to permit the driving of the vehicle.

According to the driving condition monitoring system of the seventh aspect, the recording medium is an IC card configured as a driver's license, a car insurance certificate, or a car verification. That is, since a driver's license or the like may be converted to an IC card in the near future, if the IC card is applied to the system of the present invention, personal information associated with the driver's license or the like can be used or the license can be used. It is suitable for managing violation information at the time of rewriting etc.

According to the operating condition monitoring system of the eighth aspect, when the roadside transmitter is installed at an intersection where a traffic signal is arranged, its display becomes "red" in conjunction with the traffic signal. Information indicating that the user is present. Then, the in-vehicle device violation determination means determines that the signal is "ignored" if the driving state of the vehicle is "running" when the information is received. You will definitely be able to understand.

According to the driving condition monitoring system of the ninth aspect, the roadside transmitter transmits information indicating "temporary stop" when the roadside transmitter is installed at an intersection where the traffic rule "temporary stop" is established. To do. Then, when the violation determination means of the vehicle-mounted device determines that the driving state of the vehicle is "running" when the information is received, it determines that it is a "temporary suspension violation", so that the "temporary suspension violation" is performed. You will definitely be able to understand.

According to the driving condition monitoring system of the tenth aspect, the violation determining means obtains the safe inter-vehicle distance based on the speed of the vehicle acquired by the driving information acquiring means, and the front vehicle is measured by the inter-vehicle distance measuring means. If the vehicle-to-vehicle distance between and is less than the safe vehicle-to-vehicle distance, it is determined that "the vehicle-to-vehicle distance is not maintained". Therefore, by determining "not maintaining inter-vehicle distance",
Even on the road where the roadside transmitter is not installed, it is possible to monitor whether or not the appropriate driving is being performed by determining "not maintaining the inter-vehicle distance".

According to the operating condition monitoring system of the eleventh aspect, the violation determining means measures the time period during which the state determined as "non-holding of inter-vehicle distance" is continued, and the time period also constitutes part of the information. To do. In other words, by grasping the time when the vehicle is not "holding the following distance", it is possible to determine whether the action is accidental or intentional or daily. You can

According to the operating condition monitoring system of the twelfth aspect, the calculating means calculates the dangerous driving index based on the information judged by the violation judging means, and the dangerous driving index is calculated by the driver of the corresponding vehicle. Used to calculate the amount to be paid. Therefore, for example, if a dangerous driving index is used when calculating a certain tax burden rate or a vehicle insurance premium, it is possible to impose a fair burden on each driver based on the violation information.

According to the operating condition monitoring system of the thirteenth aspect, the roadside transmitter also transmits the position information of the place where the roadside transmitter is installed, and the vehicle-mounted device stores the position information received from the roadside transmitter. Then, by making a time-sequential comparison, it is possible to easily determine the traveling direction of the vehicle by utilizing the infrastructure in which the roadside transmitter is installed.

The card device 15 is a so-called reader / device for transferring data to / from an IC card (recording medium) 18.
A writer. The IC card 18 is assumed to be configured as a driver's license. The vehicle signal input interface 16 is an in-vehicle LAN interface for obtaining necessary information from switches, sensors and the like arranged in various parts of the vehicle via the ECU. Examples of the information include an ACC (accessory) signal, vehicle speed information, parking brake (PKB) information, and the like.
The front inter-vehicle detection sensor 17 measures the inter-vehicle distance to the front vehicle using, for example, laser light.

Further, since the IC card 18 records the information about the violation of the traffic rules which occurs when the vehicle is driven as described later, unless the driver sets the IC card 18 on the in-vehicle device 5. The control unit 10 is configured to cooperate with the body ECU or the engine ECU via the in-vehicle interface 14 so that the vehicle cannot run.

FIG. 3 is a block diagram showing the contents of the control program executed by the control unit 10 by function. The control program is the operating system (O

Next, the operation of this embodiment will be described with reference to FIGS. FIG. 4 shows the control unit 1 of the vehicle-mounted device 5 mounted on the truck 3 when the truck 3 tries to pass through the intersection 1 as shown in FIG. 1, for example.
It is a flow chart which shows the contents of control processing by 0.
In this case, the processing units 21, 24, 26 to 28 of the control unit 10
Works. Further, FIG. 5 shows the roadside transmitter 40 at the intersection 1.
6 is a timing chart showing an example of processing performed by the vehicle-mounted device 5 and the vehicle-mounted device 5.

First, the traffic information communication processing unit 2 of the control unit 10
7 waits until the traffic information transmitted from the roadside transmitter 40 is received (step A1), and when the traffic information is received (“YE
S ”), it is determined whether the received information indicates the signal color of the traffic light 2 (step A2). That is, FIG.
As shown in (a), the roadside transmitter 40 constantly transmits the information on the signal color of the traffic light 2 by the short-range wireless communication,
The vehicle-mounted device 5 mounted on the vehicle passing through the intersection 1 receives the wireless signal by the narrow band wireless device 6 for traffic information.

At step A2, if the received information does not indicate a signal color ("NO"), the process returns to step A1. If it indicates a signal color ("YES"), the signal ignoring monitoring processing section 21 It is determined whether the color is "blue" (step A3). If it is "blue"("YES"), the process returns to step A1. That is, there is no problem with the truck 3 passing through the intersection 1 when the traffic light 2 is “blue”.

On the other hand, in step A3, if the signal color of the traffic light 2 is not "blue"("NO", that is, "yellow" or "red"), the signal ignoring monitoring processing unit 21 is in the control unit 10. The signal ignoring status is reset to "0" in the memory of the vehicle (step A4), and the vehicle signal input processing unit 28
Determines whether the truck 3 is stopped based on the vehicle speed information (step A5).

Here, as shown in FIG. 5B, the vehicle speed pulse of the truck 3 (the output signal of the vehicle speed sensor) is output at substantially constant intervals, although the signal is "red". If no tendency to decelerate is seen, it indicates that the truck 3 is ignoring the red light and trying to enter the intersection 1. Therefore, the signal disregard monitoring processing unit 21 determines “NO” in step A5, and the peripheral vehicle communication processing unit 26
Informs the surrounding vehicle of the danger by the short-range wireless device 7 for the surrounding vehicle (step A6, see FIG. 5C). In this case, as shown in FIG. 1, the passenger vehicle 4 located behind the truck 3 and the vehicle located on the side not shown are notified.

The determination in step A5 is not limited to the output signal of the vehicle speed sensor, but may be determined from the wheel sensor, speedometer signal, brake state, and the like.

The vehicle-mounted device 5 of the passenger car 4 which has received the warning information uses, for example, a notification means (speaker or the like) for voice guidance arranged in the navigation device 11,
For example, a voice such as "dangerous" or "a vehicle ahead is approaching with a red light" is output to warn an occupant.

That is, when the vehicle traveling in the front has a high vehicle height and a wide vehicle width like the truck 3, the passenger vehicle 4 located behind the vehicle 3 sufficiently grasps the condition on the road in front of the truck 3. There are things you can't do. For example, the hatched area in FIG. 1 is a blind spot. In such a case, if the front truck 3 ignores the signal and enters the intersection 1, the passenger car 4 may also enter the intersection 1 subsequently, which is dangerous. Therefore, by informing the rear passenger car 4 of the violation information of the front truck 3 to give a warning, the driver of the passenger car 4 can stay at the intersection.

Further, at the intersection 1, a vehicle located on the side of the truck 3 may try to take off before the traffic light changes to "blue", and if the start timing is advanced, a collision may occur. Therefore, by giving a warning in advance, it is possible to discourage the start of a closeout.

Then, the traffic information communication processing unit 27 determines whether or not the traffic information transmitted from the roadside transmitter 40 is still received (step A7). That is, track 3
If the vehicle is passing through the intersection 1, the traffic information is continuously received, so the process returns to step A5 while the traffic information is being received.

When the truck 3 completely crosses the intersection 1 and no longer receives traffic information (step A7,
“NO”, FIG. 5C), the signal neglect monitoring processing unit 21
After the signal ignoring status is set to "1" (step A8), the process proceeds to step A9. That is, in this case, the traffic signal is violated because of "ignoring the signal".

Then, the IC card processing unit 24 causes the IC card 18 to display the above history information (signal disregard status "1", for example, intersection 1 (Aichi prefecture * city * town * intersection).
On December 6, 2001 at 23:28:03, "Ignore the signal," and so on (Step A
9, FIG. 5D and FIG. 6), the traffic information communication processing unit 27.
Transmits the history information to the outside (for example, a traffic management center of police) using the history notification wide area radio 8 (step A10, see FIG. 5D). Then, the process returns to step A1.

In step A5, if the signal disregard monitoring processing section 21 determines ("YES"), the track 3
There are two cases, i.e., when the vehicle stops at the traffic light "yellow" or "red", or when the traffic light "yellow" or "red" is ignored and the vehicle stops inside the intersection 1. Then, the vehicle signal input processing unit 28 waits until the truck 3 starts based on the vehicle speed information (step A11), and when the truck 3 starts (“YES”), steps A1 to A
The same process as in step 3 is performed, and it is determined whether the signal color of the traffic signal 2 received at that time is "blue" (step A1).
2).

At step A12, the signal color is "blue".
If so (“YES”), the process proceeds to step A9) and the IC
The card processing unit 24 displays the above-mentioned history information (signal disregard status “0”, for example, intersection 1 (Aichi prefecture * city * town * intersection) on IC card 18 at 23:02 on December 6, 2001.
8 minutes 03 seconds pass, etc.). Also,
If the signal color is not "blue" in step A12 ("NO"), the signal ignoring monitoring processing unit 21 proceeds to step A12.
Go to 8. That is, also in this case, the traffic signal is violated as "ignoring the signal".

Here, in FIG. 6, in step A9, I
It shows an example of information recorded in the C card 18. The content of information is roughly divided into history content 31, insurance policy information 32, latest detailed history (No. 1) 33, latest detailed history (No. 2) 34, license information 35, deduction information 36, etc. There is.

The history contents 31 include, for example, "the number of traffic lights passing through the intersection", "the number of times the traffic signal is ignored", "the number of times when the temporary stop intersection is passed", "the number of times when the temporary stop is ignored", "total running time",
It includes items such as "safe inter-vehicle distance non-holding time" and "history start date and time". The “number of times of passing the signal-equipped intersection” is the cumulative number of times the vehicle has passed the intersection where the image-side transmitter 40 is installed, and the “number of times the signal is ignored” indicates the cumulative number of times the vehicle has ignored the signal. The “total traveling time” is the cumulative traveling time of the vehicle, and the “history start date and time” indicates the date and time when the vehicle-mounted device 5 is installed in the vehicle and the history recording is started. In addition, of these, "the number of times of stop intersection passing",
"Number of times suspension is ignored" and "Safety inter-vehicle distance non-holding time"
This will be described in another embodiment described later.

The insurance policy information 32 is related to the contract contents of the vehicle insurance (compulsory or voluntary) to which the occupant of the vehicle joins, and the contents determined for each insurance company are recorded. The latest detailed history 33, 34 is a detailed recording of the contents of the two most recent ones of the information recorded as violations, and includes “position information”, “time”, and “vehicle N”.
o. , "Contents of violation", etc. Of course, three or more records may be recorded depending on the storage capacity. License information 35
And the deduction information 36 is information managed by the police, the former is information described in a general driver's license,
The latter is information on the points deducted due to the violation of traffic rules.

Of these information, for example, history contents 31
The insurance policy information 32 and the insurance policy information 32 are managed by the security A, and the remaining information is managed by the security B. That is, since these pieces of information are information relating to the privacy of individuals, it is not desirable that any person can easily read them. Therefore, a person who does not have the information (password, personal identification number, encryption key, etc.) for obtaining the read permission according to each management form cannot read the information recorded in the IC card 18. It has become.

The level of security A is set to be higher than the level of security B, and in order to read out the information of security A, a more advanced canceling process is required.

As described above, according to the present embodiment, the roadside transmitter 40 transmits the information regarding the traffic regulation to be fulfilled at the intersection 1, which is the installation point, by the radio wave signal, and the vehicle-mounted device 5 is transmitted from the roadside transmitter 40. When the transmitted information is received in the reception area centered on the installation point, the control unit 10
When that information is compared with the vehicle information acquired by the vehicle signal input interface 16 at the time of receiving the information, and it is determined that the driving of the truck 3 violates the traffic rules to be enforced at the intersection 1, Information is recorded on the IC card 18 and transmitted to the police by radio signals.

That is, according to the system of the present invention, the truck 3
It is possible to monitor the driving status of the vehicle and to leave concrete evidence when a traffic rule violation occurs. The police can use the information to detect traffic violations without fail, so that the person who drives the truck 3 must raise awareness that he / she must comply with traffic regulations. Therefore, the traffic manners of the driver can be reliably improved, and the occurrence of traffic accidents can be reliably suppressed.

Further, the roadside transmitter 40 transmits information indicating that the display is "red" in conjunction with the traffic light 2, and the control unit 10 of the vehicle-mounted device 5 receives the information. If the operating state of the truck 3 is "running", it is determined to be "ignoring the signal", so that it is possible to reliably know that the "ignoring the signal" is performed.

When the vehicle-mounted device 5 of the passenger car 4 receives the information transmitted by the vehicle-mounted device 5 of the truck 3 located in the front, the navigation device 11 gives a warning based on the content of the information. The driver of can avoid being caught by the truck 3 and entering the intersection 1.

Since the vehicle-mounted device 5 records the information determined by the control unit 10 in the IC card 18, it can be used to read the recorded violation information as necessary and perform various evaluations. it can. In addition, IC card 18
By using, the information is recorded when a violation occurs in the driving performed in each vehicle, so that the history of the violation can be recorded for each driver.

Further, since the vehicle-mounted device 5 performs the security processing so that the information stored in the IC card 18 can be read only by the specially authorized person, the information concerning the privacy of the individual is specially authorized. Only those who are reading can read it.

In addition, since the IC card 18 is configured as a driver's license, when the driver's license is actually converted into an IC card in the near future, personal information associated with the driver's license can be used, It is suitable for the police (public security) side to manage violation information when rewriting a license. If the points are deducted according to the history information, the process of deducting points can be made transparent and the handling of each driver (for example, the burden of fines) can be made fair. .

(Second Embodiment) FIGS. 7 to 9 show a second embodiment of the present invention. The same parts as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted. Only the part will be described. The second embodiment is a case where the passenger car 43 passes through an intersection 42 where the traffic signal 2 is not installed and the "stop" sign 41 is installed. In this case, the roadside transmitter 44 installed at the intersection 42 continuously transmits a signal indicating “pause” (see FIG. 9A).

Next, the operation of the second embodiment will be described with reference to FIGS. 8 and 9. FIG. 8 shows, as shown in FIG.
When the passenger car 43 tries to pass through the intersection 42, the control unit 10 of the vehicle-mounted device 5 mounted on the passenger car 43.
5 is a flowchart showing the contents of control processing by the. Further, FIG. 9 is a timing chart showing an example of processing performed by the roadside transmitter 44 and the vehicle-mounted device 5.

In the second embodiment, the processing contents performed by the control unit 10 of the vehicle-mounted device 5, that is, the functioning program module is partly different from that of the first embodiment, and the processing units 22, 24 of the control unit 10 are 27 and 28 are functioning.

First, the traffic information communication processing unit 2 of the control unit 10
7 waits until the traffic information transmitted from the roadside transmitter 44 is received (step B1), and when the traffic information is received (“YE
S ”), and determines whether the received information indicates“ temporary stop ”(step B2). In step B2, if the received information does not indicate "temporary stop"("NO"), the process returns to step B1. If it indicates "temporary stop"("YES"), the temporary stop monitoring processing unit 2
2 resets the temporary stop ignoring status to "0" in the memory in the control unit 10 (step B3), and the vehicle signal input processing unit 28 determines whether or not the passenger vehicle 43 is stopped based on the vehicle speed information. (Step B4).

Here, as shown in FIG. 9B, the vehicle speed pulse (the output signal of the vehicle speed sensor) of the passenger vehicle 43 is continuously output even though the signal indicating "pause" is received. If it is displayed, it means that the passenger car 43 ignores the “pause” and is about to enter the intersection 42. Therefore, the suspension monitoring processing unit 22 determines “NO” in step B4, and proceeds to step B5.

At step B5, the traffic information communication processing unit 27 determines whether or not the traffic information transmitted from the roadside transmitter 44 is still received, and the traffic information is transmitted before the passenger vehicle 43 stops at step B4. When the reception is interrupted (“NO”), the suspension monitoring processing unit 22 sets the suspension ignoring status to “1” (step B6).
That is, in this case, the traffic is in violation of the traffic rules due to "temporary non-stop of the designated place".

In the following steps B7 and B8, the first
Similar to A9 and A10 in the embodiment, the IC card processing unit 24 causes the IC card 18 to display the above history information (temporary stop disregard status “1”, for example, the intersection 42 (Aichi prefecture * city * town * intersection) in 2001. December 6, 23:28 0
In 3 seconds, write "passing due to violation of" pause "" (see FIG. 9C and FIG. 6), and the traffic information communication processing unit 2
7 transmits the history information to the outside using the history notification wide area radio 8 (see FIG. 9D). Then, the process returns to step B1.

Further, if the passenger car 43 is stopped before the traffic information communication processing unit 27 determines "NO" in step B5 and the determination is "YES" in step B4, the temporary stop monitoring processing unit 22 determines that the vehicle is in step B7. Move to. That is, as shown in FIG. 9 (e), since the passenger car 43 has executed the temporary stop, the IC card processing unit 24
The above history information (temporary disregard status "0", for example, intersection 42 (Aichi prefecture * city * town * intersection) on card 18
On December 6, 2001 at 23:28:03, "Pause" and so on).

According to the processing in steps B4 and B5, "temporary non-stop at the designated place" is not recorded even when the passenger car 43 stops in a state where it completely enters the intersection 42. However, the person who actually drives is
It is usually unthinkable to stop the passenger car 43 at such a halfway position, and a temporary stop is performed (or
It is assumed that either the stop line is slightly overrun to stop) or the pause is completely ignored. Therefore, it is considered that there is no problem in practice even with the above-mentioned processing form (it should be noted that the same can be applied to the case of the first embodiment).

As described above, according to the second embodiment, when the roadside transmitter 44 is installed at the intersection 42 where the traffic rule "temporary stop" is set, the roadside transmitter 44 transmits information indicating "temporary stop". Send. Then, if the operating state of the passenger car 43 is "running" when the control unit 10 of the vehicle-mounted device 5 receives the information, the control unit 10 determines "temporary suspension violation", and therefore, "temporary suspension violation" is performed. You will definitely be able to understand what was broken.

(Third Embodiment) FIGS. 10 to 12 show a third embodiment of the present invention. The same parts as those in the first embodiment are designated by the same reference numerals and their description is omitted. Only the part will be described. The third embodiment is a case on a road where the traffic signal 2 and the roadside transmitter are not installed and the intersection is not set.

As shown in FIG. 10, it is assumed that a passenger car 52, a truck 53, and a passenger car 54 are traveling on a road 51 in this order. The vehicle-mounted device 5 mounted on the truck 53 measures the inter-vehicle distance from the front passenger vehicle 52 by the front inter-vehicle detection sensor (inter-vehicle distance measuring means) 17.

FIG. 11 is a flow chart showing the contents of control processing by the control unit 10 of the vehicle-mounted device 5.
4 is a timing chart showing an example of processing performed by the vehicle-mounted device 5. When the inter-vehicle distance monitoring processing unit 20 of the control unit 10 acquires the vehicle speed information of the truck 53 detected based on the vehicle speed pulse signal via the vehicle signal input processing unit 28 (step C1), the appropriate inter-vehicle distance according to the vehicle speed information is acquired. The distance L1 is calculated (step C2).

The proper inter-vehicle distance L1 is, for example, a vehicle speed of 100 k.
The standard guideline is 100 m for m and 80 m for vehicle speed of 80 km, but a longer distance is required when the road surface is wet in the rain. For example, a vehicle may be provided with a rainfall sensor, and the calculation may be performed according to the rainfall detected by the sensor. Further, without providing the rainfall sensor, for example, the rainfall amount may be estimated by obtaining the operating state of the wiper (switching state of low speed, normal, high speed, etc.) via the vehicle signal input processing unit 28. Further, the proper inter-vehicle distance L1 may be calculated according to the weight by obtaining the weight information of the vehicle. For example, in the case of the heavy truck 53, the distance L1 is set longer.

Next, when the current inter-vehicle distance L2 is detected by the inter-vehicle distance signal processing unit 29, step C3), the distance L1 is detected.
Is greater than the distance L2 (step C4). If the former is less than or equal to the latter (“NO”), step C
If the former is larger than the latter (“YES”), the timer A is reset and started (step C5). Here, the timer A is, for example, a software timer held by the inter-vehicle distance monitoring processing unit 20.

Then, the peripheral vehicle communication processing unit 26 notifies the peripheral vehicle of the danger by the short-range radio 7 for the peripheral vehicle (step C6, FIG. 12 (c), (a)).
reference). In this case, as shown in FIG.
A notification is given to the passenger car 54 located behind the vehicle.

At this time, the passenger car 5 that has received the warning information
Similarly to the first embodiment, the vehicle-mounted device 5 of No. 4 uses the notification means for voice guidance arranged in the navigation device 11, for example, "is dangerous" or "the inter-vehicle distance of the vehicle in front is secured. The occupant is warned by outputting a voice such as "No."

That is, when the truck 53 is traveling in front, the passenger car 54 located behind the truck 53 is on the road in front of the truck 53, that is, whether or not a vehicle is present in front of the truck 53. It may not be possible to fully grasp whether or not the vehicle-to-vehicle distance is sufficiently secured. Therefore, if a warning is given to the rear passenger car 54 by informing the passenger compartment 54 of the truck 53, the driver of the passenger car 54 can secure a sufficient vehicle distance to the truck 53 and improve safety. You can

Subsequently, the inter-vehicle distance monitoring processor 20 detects the current inter-vehicle distance L2 as in step C3 (step C7), and determines whether or not the distance L1 is smaller than the distance L2 ( Step C8). If the former is more than the latter
(“NO”) The process returns to step C6, and if the former is smaller than the latter (“YES”), the timer A stops counting (step C9, see FIG. 12C).

At the subsequent step C10, the IC card processing section 24 writes the history information into the IC card 18.
(See FIG. 12D and FIG. 6). The history information in this case is
It is the time measured by the timer A in steps C5 to C9. For example, the information is such that the safe inter-vehicle distance is not held for 10 minutes. Then, in the subsequent step C11, the traffic information communication processing unit 27 transmits the history information to the outside by using the history notification wide area radio 8 (see FIG. 1).
2 (e)), and returns to step C1.

As described above, according to the third embodiment, the control unit 10 of the vehicle-mounted device 5 obtains the safe inter-vehicle distance L1 based on the speed of the truck 53, and the actual inter-vehicle distance L2 at that time is the safe inter-vehicle distance. If the distance is less than L1, it is determined that “inter-vehicle distance is not maintained”. Therefore, even on the road where the roadside transmitter 40 is not installed, whether the inter-vehicle distance is secured is monitored and whether or not proper driving is being performed. Can be monitored.

Further, the control unit 10 "does not hold the following distance"
By measuring the time that the condition is judged to be continued and using that time as a part of the history information, by grasping the time when the "inter-vehicle distance is not maintained" condition, the action is accidental. It is possible to discriminate whether it has occurred intentionally or is intentionally or routinely performed.

(Fourth Embodiment) FIGS. 13 to 15 show a fourth embodiment of the present invention. In the fourth embodiment, the vehicle insurance premium is calculated by transmitting the history information recorded in the IC card 18 by the vehicle-mounted device 5 as described above to the insurance company which has a vehicle insurance contract as an outside. It is supposed to be applied in some cases. That is, as shown in FIG.
The history notification wide area wireless device 8 of the vehicle-mounted device 5 accesses the public communication network 62 via the base station 61 and transmits the history information to the server (calculation means) 64 of the insurance company 63.

FIG. 14 shows that, when the vehicle insurance contract is renewed, the server 64 indicates that the policyholder is within the contract period (one year).
6 is a flowchart showing the processing contents for calculating an insurance premium in accordance with the driving violation situation that has been carried out. The server 64 first calculates the dangerous driving index A (step D1). The dangerous driving index A is (dangerous driving index A) = (number of times signal is ignored)
It is calculated by / (the number of passing intersections with signal).

Next, the server 64 calculates the dangerous driving index B (step D2). The dangerous driving index B is calculated by (dangerous driving index B) = (number of times of ignoring temporary stop) / (number of times of passing temporary stop intersection).

Subsequently, the server 64 calculates the dangerous driving index C (step D3). The dangerous driving index C is calculated by (dangerous driving index C) = (safe driving inter-vehicle distance non-holding time) / (total running time).

Here, the dangerous driving indexes A to C are actually calculated based on the history information shown in FIG. 6 as follows. (Dangerous driving index A) = 997 (times) / 5619 (times) =
0.18 (Dangerous driving index B) = 259 (times) / 7442 (times) =
0.03 (Dangerous driving index C) = 14 (days) / 204 (days) =
0.07 That is, 18%, 3%, and 7%, respectively.

Then, the server 64 executes the steps D1 to D1.
The insurance premium rate is determined based on each dangerous driving index A to C obtained in D3 (step D4). The final dangerous driving index used here is, for example, a simple sum of the indices A to C, or the product obtained by multiplying the degree of danger of each violation content leading to the occurrence of a traffic accident as each weight coefficient. You may. For example, when a simple sum is calculated, it becomes A + B + C = 18 + 3 + 7 = 28 (%).

FIG. 15 is a table for determining the insurance premium rate, which is held by the server 64. In the above example, the dangerous driving index is 20% or more, so the insurance premium ratio is doubled. In this case, it is possible to evaluate that a contractor having a higher dangerous driving index is more likely to have a traffic accident, and accordingly, the insurance premium is set to be higher accordingly. Then, the server 64 calculates the insurance premium by multiplying the standard insurance premium by the insurance premium rate determined in step D4 (step D5).

As described above, according to the fourth embodiment, the server 64 of the insurance company 63 calculates the dangerous driving index on the basis of the violation information determined by the control unit 10 of the vehicle-mounted device 5, and calculates the dangerous driving index. , It is used to calculate the insurance premium for vehicle insurance that the driver of the corresponding vehicle should bear, so that it is possible to impose a fair burden on each insurance policyholder based on the violation information.

Further, in the conventional vehicle insurance, the contract is made for the vehicle, but according to the present invention, even when one driver drives a plurality of vehicles, the in-vehicle device is If the vehicle is installed, the driving history of the driver can be continuously grasped. Therefore, it is possible to provide a driver insurance service for individual drivers, which did not exist in the past.

The present invention is not limited to the embodiments described above and shown in the drawings, and the following modifications and expansions are possible. The warning process in the first embodiment is
You may go only to the vehicle located behind. Also,
Also in the second embodiment, the same warning process as in the first embodiment may be performed. In addition, for example, when a direction is not instructed during a right turn or a left turn, or when a direction is instructed immediately before a right turn or a left turn, it may be determined that the violation is “failure to signal” and the process may be performed. The roadside transmitter may be installed at an appropriate place on the road, not limited to the point where the traffic light is not installed or the intersection. For example, the roadside transmitter may transmit the speed limit information of the installation point, and the vehicle-mounted device side may determine “speed overrun” or the like.

The warning means is not limited to the one using the navigation device 11, but an independent warning means may be provided.
Further, the sound is not limited to the sound, and a warning sound may be generated or a warning may be given by a display. For example, the in-vehicle device is configured to record personal information for permitting driving of the vehicle, and the personal information recorded in the recording medium is collated to determine whether or not the driving of the vehicle is permitted. Is also good. In the third embodiment, "inter-vehicle distance is not maintained"
It is not necessary to measure the time, and only the occurrence of "non-holding of the inter-vehicle distance" may be determined and the number of occurrences may be used as the history information. The processes of the first to third embodiments may be performed concurrently in parallel.

In the fourth embodiment, the present invention is not limited to the application for the vehicle insurance premium, but may be applied for calculating the burden rate of weight tax, for example (for example, as the dangerous driving index increases, the tax increases. To increase the burden rate). The area of the radio signal transmitted from the roadside transmitter is
The rear end of the area may be near the stop line by being positioned on the front side (the direction in which the vehicle arrives at the intersection) with respect to the state shown in FIGS. 1 and 7. With this setting, it is possible to detect the signal disregard and the pause disregard more strictly. The IC card 18 does not have to record information as a driver's license, but may have other information such as an insurance card for automobile insurance and information for vehicle verification.

Writing of information to the IC card 18 and transmission of information to the outside may be performed, for example,
The fact that the violation has occurred is stored in a buffer (RAM) in the control unit, and the information held in the buffer is collectively collected at the time when it is detected that the vehicle has stopped due to the ACC signal being turned off. It may be written in the card 18 or transmitted to the outside in a batch. With such a configuration, it is possible to reduce the load on the IC card 18 associated with writing and prolong the service life. In addition, it is possible to reduce the number of communication packets by transmitting the data collectively to some extent and to keep the communication charge low. The recording medium is not limited to the IC card 18, and may be a non-volatile recording medium such as a memory card or a memory stick without a built-in microcomputer, a floppy (registered trademark) disk or a magnetic card. The vehicle-mounted device may have only one of the function of recording the violation information in the recording medium and the function of transmitting the information to the outside.

The calculation means is not limited to the server 64 on the insurance company 63 side in the fourth embodiment, but may send only the result calculated by the in-vehicle device having the function to the insurance company 63 side. The vehicle-mounted device 5 can constantly monitor the traveling direction of the vehicle by including the current position detection unit (GPS) 9 or the navigation device 11. However, for example, a roadside transmitter is installed by itself. The in-vehicle device determines the traveling direction of the vehicle by storing the position information received from the roadside transmitter in memory etc. and comparing it in time series. It may be configured to do so. According to this structure, it is possible to easily determine the traveling direction of the vehicle every time the vehicle passes the installation location by using the infrastructure in which the roadside transmitter is installed.
