  Various methods have been proposed as means for providing traffic information, but in reality, information relating to traffic regulations (road traffic law) is limited to television, newspapers, radio, or the Internet. If the information source is limited in this way, the driver and passenger's memory will be relied on until boarding, and compliance with laws and regulations will not remain.

  Even in the above-mentioned patent documents, although information on road signs and speed limits can be acquired, no provision or revision of traffic regulations is provided, and these still depend on memories of individual drivers and the like.

  An object of the present invention is to provide a device capable of promptly and accurately notifying a vehicle occupant when a traffic regulation is established or revised.

  The present invention includes a receiving means for receiving information related to the establishment or revision of traffic regulations, a storage means for storing the received information, and a control means for selecting specific information from the information stored in the storage means. And output means for outputting the selected information.

  In one embodiment of the present invention, the control means selects information relating to a date within a certain period from the current date.

  In another embodiment of the present invention, the storage unit deletes information relating to a date before a certain period from the current date.

  According to the present invention, it is possible to promptly and accurately notify a vehicle occupant even when traffic regulations are established or revised.

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

  FIG. 1 shows a configuration block diagram of an in-vehicle device 1 in the present embodiment. The in-vehicle device 1 includes an external communication unit 10, a control device 12, an in-vehicle database D / B 14, a GPS antenna system 16, a drawing device 18, and an audio output device 20.

  The communication means 10 with the outside acquires information relating to traffic regulations transmitted from an external information source, for example, a radio base station. The communication means 10 with the outside is, for example, an FM receiver, and receives information related to FM traffic regulations. Or the communication means 10 with the outside is, for example, a VICS (Vehicle Information and Communication System) receiver, and receives information on traffic regulations transmitted from the VICS base station. As a communication means 10 with the outside, a mobile phone of a vehicle occupant can also be used. A mobile phone is set in a predetermined cradle, and information on traffic regulations from the base station is received.

  Information on traffic regulations is information on the establishment or revision of traffic regulations (Road Traffic Law). Includes establishment and revision of penal regulations. This includes, for example, mandatory seat belts for the rear seat occupants of the vehicle. If traffic regulations are established or amended, the base station will respond at the appropriate timing (it is the timing after the date when the traffic regulations were promulgated, but it may be the timing before the promulgation date). Wireless transmission from. The external communication means 10 supplies the received information on the traffic laws to the control device 12.

  The in-vehicle database D / B 14 is composed of a recording medium that can hold information electromagnetically or optically, such as a hard disk, a semiconductor memory, an optical disk, or the like, and stores information related to traffic regulations received by the communication means 10 with the outside.

  The GPS antenna system 16 receives GPS radio waves from GPS satellites and supplies them to the control device 12.

  The control device 12 is composed of a microprocessor, receives information on traffic regulations from the communication means 10 with the outside, supplies it to the in-vehicle database D / B 14 and stores it. In addition, the control device 12 acquires various vehicle information such as the vehicle speed, the steering angle, and whether or not the seat belt is worn. The control device 12 may function as a microprocessor of the navigation system, and measures the position of the vehicle based on GPS radio waves and vehicle information.

  The drawing device 18 is a display device such as an LCD or an organic EL, and displays information related to traffic regulations as characters, graphics, or the like.

  The voice output device 20 outputs information related to traffic regulations by voice.

  The drawing device 18 and the audio output device 20 can also be used as a display device and an audio output device in the navigation system.

  In such a configuration, information relating to traffic regulations received by the external communication means 10 is stored and accumulated in the in-vehicle database D / B 14. The control device 12 accesses the in-vehicle database D / B 14 to read out information relating to traffic laws and regulations, stores the date and time of reception or the date and time of transmission from the base station, and date data included in GPS radio waves received by the GPS antenna system 16. And compare. If the date data included in the GPS radio wave, that is, information relating to traffic regulations close to the current date, the information is displayed on the drawing device 18 and output to the audio output device 20. If the information is not information related to traffic regulations close to the date data included in the GPS radio wave, that is, information older than the current date is not output to the drawing device 18 or the audio output device 20. By outputting only information related to traffic regulations having a date close to the current date, it is possible to efficiently notify only the traffic regulations recently enacted or recently revised to vehicle occupants.

  FIG. 2 shows a processing flowchart of the present embodiment. First, information, that is, information related to traffic regulations is obtained by the communication means 10 with the outside (S101). The information to be obtained may include information other than information related to traffic regulations. Next, the control device 12 stores and accumulates information related to traffic regulations in the in-vehicle database D / B 14 among the obtained information (S102). When information related to traffic regulations is stored in the in-vehicle database D / B 14, information reception date / time or transmission date / time is also stored. The above process is repeatedly executed at an arbitrary timing while the ignition key of the vehicle is turned on. Even when the ignition key of the vehicle is turned off, information relating to traffic regulations may be stored in the in-vehicle database D / B 14 by being repeatedly executed at regular or irregular timings.

  Next, at the timing when the vehicle occupant gets into the vehicle and turns on the ignition key, the control device 12 accesses the in-vehicle database D / B 14 to read the accumulated information and collates it with date data included in the GPS radio wave ( S103). Then, it is determined whether the date of the information in the in-vehicle database D / B 14 is older than the GPS date (S104). Specifically, this determination is performed by setting a period before a predetermined period, for example, one week before the GPS date, and determining whether or not the information date is included within this period.

Specifically, it is assumed that the information stored in the in-vehicle database D / B 14 is as follows.
(1) Reception date: July 1, 2008, Information: Information on the establishment of traffic regulations A (2) Reception date: July 30, 2008, Information: Information on revision B of traffic regulations (3) Reception Date: August 15, 2008, Information: Information on Traffic Regulation Revision C

  If the GPS date is August 20, 2008 and one week ago is set as the predetermined period, it is determined that the information (1) and (2) are old, and the information (3) is new information. It is determined that there is. Information determined to be YES in S104, that is, information that is old is deleted from the in-vehicle database D / B 14 (S106). On the other hand, NO, that is, information determined to be new in S104 is output to the drawing device 18 and the audio output device 20 to notify the driver and other vehicle occupants (S105).

  Thus, since the latest information on traffic regulations is output to the drawing device 18 and the audio output device 20 at the timing when the ignition key is turned on, the vehicle occupant can know the latest information every time the ignition key is turned on. This makes it easier and more reliable to comply with laws and regulations.

  In the present embodiment, NO is determined in S104, that is, when there is no information determined to be new, the vehicle occupant is not notified at all. This means that there is no up-to-date information on traffic regulations, so the vehicle occupant only needs to drive the vehicle according to existing traffic regulations.

  Further, in the present embodiment, it is determined whether or not the information related to traffic regulations is old using date data included in GPS radio waves. However, date data obtained from a vehicle-specific clock may be used. Other date data acquired from may be used. In short, the current date data may be acquired by some means or method.

  Moreover, in this embodiment, it is determined whether the information regarding the traffic regulations stored in the in-vehicle database D / B 14 is old or not, depending on whether it is included within a predetermined period from the current date. In addition to being fixed, it may be variable. For example, the default predetermined period is set to one week ago, and the vehicle occupant changes the period as appropriate to set it three days ago, ten days ago, or two weeks ago.

  Moreover, in this embodiment, new information will be repeatedly alert | reported among the information regarding the traffic regulation accumulate | stored in the vehicle-mounted database D / B14. For example, if the predetermined period is one week ago, the information (3) is repeatedly notified from August 15 to August 22. Therefore, the control device 12 counts the number of notifications for the notified information, and if it is notified a predetermined number of times, for example, three times, the control device 12 performs control so that it will not be notified afterward even though it is determined to be new. May be.

  Moreover, in this embodiment, although the information regarding traffic regulations is alert | reported, you may accumulate | store and alert | report only the information regarding the revision regarding penal regulations among the information regarding traffic regulations in the vehicle-mounted database D / B14.

  In the present embodiment, information related to traffic regulations is output to the drawing device 18 and the voice output device 20, but may be output to either the drawing device 18 or the voice output device 20, and You may select the apparatus which should be output according to the content. The contents of information related to traffic regulations can be analyzed by extracting keywords included in the information related to traffic regulations. For example, when the keyword “seat belt” is included in the information related to traffic regulations, an image indicating the seat belt position is displayed on the drawing device 18.

  When outputting to the voice output device 20, in addition to converting the information related to traffic regulations into voice as it is and outputting it, a summary using keywords may be created and output. Alternatively, it may be output in a plurality of stages. For example, the voice simply outputs “There are two pieces of information on traffic regulations. Please check this information before starting.” And the menu for two cases is displayed on the drawing device 18. When the occupant selects this menu, detailed information is displayed. If information related to traffic regulations is particularly important information, set a flag in this information and confirm that the passenger has accessed this information before starting the engine or any other mechanism required for vehicle operation. It is possible to allow it.
