  The present invention relates to a traffic violation warning device and system, and more particularly to a traffic violation warning device and system that can surely recognize regulatory signs that are easily overlooked by beginners of driving and elderly people, and that are effective in preventing traffic violations and traffic accidents. About.

  In the conventional method in which the driver checks the road signs written on the road surface and traffic signs placed around the road, the driver overlooks the speed indication and traffic signs written on the road surface, and the driver overspeeds or is prohibited. Changing course, turning right / left, overtaking, etc. may occur. In particular, beginners of driving and elderly people often have a “disappointment”, and traffic accidents may occur if they do not drive with careful attention to road signs and traffic signs as well as other vehicles and pedestrians. In addition, beginners and young people may lose their balance on a curve due to overspeeding, resulting in an accident, but there is currently no way to run at a speed suitable for the spot. On ordinary roads, the speed limit varies considerably from 20 to 60 km. For beginners and the elderly, traffic violation and the prevention of traffic accidents due to this are important issues. Particularly in recent years, highway reverse running accidents due to overlooked signs by elderly people are becoming a social problem.

  Therefore, it is desirable to have a system that prevents traffic violations and traffic accidents by beginners who are unfamiliar with driving a car and who easily overlook surrounding regulatory signs, young people with poor attention, and elderly people with poor recognition skills. ing.

  For this purpose, Patent Document 1 proposes a speed control system in which a device that transmits radio waves including speed limit information is arranged beside a road, and the vehicle that has received the information is forcibly decelerated when the speed limit is exceeded. Has been.

  Patent Document 2 discloses an automobile speed control device having means for transmitting a speed limit command signal and a traffic signal to an automobile, means for receiving the information on the automobile side, traveling speed control means, warning display means, and the like. Has been proposed.

Japanese Patent Laid-Open No. 9-50595 JP-A-5-135298

  However, Patent Document 1 is speed limit information, and Patent Document 2 is only to decelerate the vehicle based on the speed limit information and traffic signal, or to give a warning to the driver, and other information is not considered. . In any case, a means for transmitting speed limit information and traffic signal information to the automobile is necessary, and there is a problem that the current infrastructure cannot cope.

  The present invention has been made to solve the above-mentioned conventional problems, and can use a current infrastructure to give a driver a warning regarding various regulatory information including information other than speed limit and traffic signals. It is a first problem to provide a simple traffic violation warning device.

  It is a second object of the present invention to provide a traffic violation warning system that can add a necessary infrastructure and reliably give a warning to a driver.

  The present invention provides a means for capturing regulation information relating to automobile driving, a means for detecting the automobile driving condition, and a driver when the detected driving condition violates or is likely to violate regulations. The first problem is solved by a traffic violation warning device comprising a warning means.

  Further, by further providing means for canceling the warning, it is possible to prevent an unnecessarily high warning from being given to a skilled driver or a familiar road, so that only a driver who needs the warning can be given accurately. It is a thing.

  The present invention is also characterized in that it is provided with a device that is disposed on or around a road and that transmits regulation information relating to the traveling of the vehicle, and the traffic violation warning device that is mounted on the vehicle. The traffic violation warning system solves the second problem.

  According to the traffic violation warning device according to the present invention, the current running state is maintained in the current infrastructure by the automobile itself taking in the regulation information relating to the running of the automobile using a TV camera or the like disposed in the automobile. The driver can be warned that the vehicle violates or is likely to violate regulations. Therefore, it is possible to prevent traffic accidents such as driving beginners, drivers driving on unfamiliar roads, elderly people with reduced attention, etc., and traffic accidents can be prevented.

  In particular, when a device for transmitting the restriction information is provided on or around the road, the restriction information can be reliably recognized by providing a means for capturing the restriction information on the automobile side.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  1st Embodiment of this invention is related with the traffic violation warning apparatus mounted in a motor vehicle. As shown in FIG. 1 (overall view) and FIG. TV (TV) camera 22 for imaging road signs 11 and traffic signs 12 such as speed limit, entry prohibition, right / left turn prohibition, lane change prohibition, overtaking prohibition, and the image of the TV camera 22 are processed. Based on the output of the regulation information fetching unit 32 for fetching the regulation information relating to the running of the automobile, for example, the vehicle speed sensor 24, the rudder angle sensor 26, the brake switch 28, the GPS sensor 29, etc., the running state of the automobile 20 (vehicle speed, A driving state detecting unit 34 for detecting a right / left-turn turn signal operating state, a steering operating state, a brake operating state, a driving position, etc., and whether the current driving state of the vehicle violates the regulations Or, when an alarm signal is output from the in-vehicle computer 30 including the traffic violation detection unit 36 that determines whether there is a possibility of violation if the current driving state is continued, and the traffic violation detection unit 36 of the in-vehicle computer 30, for example, For example, an alarm device 40 provided on an instrument panel for turning on a lamp or transmitting a warning sound, and a warning release switch (SW) 42 for manually releasing the warning are provided.

  As the TV camera 22, a TV camera dedicated to road / traffic sign recognition is provided in the front part of the vehicle, or a traffic accident monitoring camera scheduled to be provided between the windshield and the rearview mirror for recording a traffic accident is used. Alternatively, the road sign 11 and the traffic sign 12 can be imaged using the latest monitoring camera embedded in the front grille in the front of the vehicle.

  The regulation information capturing unit 32 of the in-vehicle computer 30 recognizes the contents of the road sign 11 and the traffic sign 12 by using, for example, a pattern recognition technique.

  When it is determined that the current driving state of the vehicle violates the regulations or that there is a possibility of violating the current driving state, the alarm device 40 is activated to warn the driver. give.

  In this embodiment, since the existing road sign 11 and traffic sign 12 are used, it is possible to warn of traffic violations and prevent traffic accidents by using the current infrastructure as it is. It becomes.

  In particular, when used in combination with a GPS device that recognizes the traveling position of an automobile, a more accurate warning is possible.

  In the first embodiment, there is no possibility of missing a traffic sign. Next, FIG. 3 shows a second embodiment of the present invention that solves this point.

  In this embodiment, in place of the road sign 11 and the traffic sign 12 of the first embodiment, a transmitter 50 that transmits regulation information related to driving of the automobile is disposed on or around the road 10, and the first embodiment is also provided. Instead of the TV camera 22, a restriction information receiver 52 is provided on the automobile 20 side.

  The restriction information transmitter 50 can be provided separately from the conventional traffic sign 12, embedded in the road 10 or the traffic sign 12, or installed on the same pole as the traffic sign 12.

  The restriction information transmitter 50 and the receiver 52 can transmit and receive restriction information by blinking of infrared light coded by an on / off time, for example, using wireless LAN technology. In addition, when using light, it is preferable to use infrared light that is invisible to human eyes, but in addition to light, radio waves, wireless, sound, electromagnetic / electrostatic induction, and the like can also be used.

  The regulation information includes not only regulation information by conventional road signs and traffic signs, but also regulation differences by time such as differences in regulations (large regulations, bus lanes, etc.), nighttime, morning, etc. Differences in regulations due to differences, congestion, and normal times can be included.

  According to the second embodiment, different driving assistances are possible depending on the type of vehicle such as small and large. Also, information is important at the reference level because the field of view is limited, especially at night. Moreover, since there are many violations in the morning, the automatic speed monitoring function is effective. Also, in a city with many obstacles, it is necessary to alleviate congestion, and runaway driving should be avoided even during normal daytime, which is effective.

  In each of the above-described embodiments, the warning switch 42 is provided. Therefore, when there is a sufficient margin on a road or a driving expert who is used to running, an unnecessary warning is given to the driver. It is possible to prevent the attention of the driver from being scraped off, and to cope with the level of the driver.
