The CU 14 includes a CPU, ROM, RAM, I / P port and the like.

The reception unit 12 mainly uses FM multiplex communication to receive wide area information, for example, information about the entire Setagaya Ward and information on the entire Metropolitan Expressway, and a beacon arranged on the side of the road. It is composed of a beacon receiving unit 12b that receives detailed information in a narrow area in the vehicle traveling direction using radio waves or light as a medium, and another receiving unit 12c that uses a car phone, a mobile phone, or the like. In this information, along with substantive information such as traffic jam information and parking lot availability information,
Time information (time stamp) indicating the time when the information is generated is added.

The information data received by the receiver 12 is EC
The data is input to the data conversion unit 20 inside the U14, and the ECU14
It is converted into a state that can be processed internally and is input to the memory 22. The information input to the memory 22 is sequentially input to the arithmetic unit 24 as the comprehensive control means. The calculation unit 24 is composed of a data determination unit 24a, a data processing unit 24b, and an image processing unit 24c. The data determination unit 24a recognizes and determines the type of input information. For example, it is determined whether the received information is information regarding traffic jam, information regarding construction, information regarding parking lot, or information regarding which time zone.

In the data processing unit 24b, based on the determination result of the data determination unit 24a, the display instruction from the input unit 18, and the route calculation result from the route calculation unit 21 which is a part of the GPS navigation system. , Display the time stamp and substance information. The route calculation unit 21 calculates a current position of the vehicle based on the direction sensor 26a and radio waves from an artificial satellite.
Based on the information from, the optimum route by which the vehicle can satisfactorily move to the desired destination is calculated , and the calculation result is input to the data processing unit 24b and the memory 22. Also,
On the display unit 16, a map of the vicinity of the current position of the vehicle or an area desired by the passenger is displayed from a vehicle-mounted map database (not shown).

Based on the time stamp processed by the data processing section 24b and the display instruction of the entity information, the image processing section 24
In c, the displayed images are combined and displayed on the display unit 16.

Next, the operation of the vehicle information display device 10 will be described using the flowcharts shown in FIGS. 2 and 3 and the display examples shown in FIGS. First, when the information having the time stamp is input from the reception unit 12 to the calculation unit 24 via the data conversion unit 20 and the memory 22, only the information in the map area currently displayed on the display unit 16 is determined ( S1
00), only that information is extracted (S101). The extraction of this information is performed according to the procedure shown in the flowchart of FIG. First, it is determined whether or not the passenger has limited the type of information to be displayed using the input unit 18 (S200). The limitation on the type of information is, for example, limitation on traffic congestion information or parking lot availability information. When the type is limited, only the time stamp of the limited information is searched (S201). Then, because the vehicle is traveling on a highway, the display unit 16
Then, it is judged whether or not only the information on the expressway is limited and displayed (S202). While driving on the highway,
Since the traffic congestion information on the expressway and the vacant information about the service area etc. are mainly needed, and the need for the information on the general road is low, only the time stamp of the information on the expressway is searched (S203). Furthermore, it is determined whether there is information thinned out from the display by the wide area display of the vehicle-mounted map (S).
204). This thinning-out is mainly performed when the information indicates a section (length) such as traffic jam and the like, and the influence of traffic jam or the like is small with respect to the size of the target area. Therefore, in the case where the wide area display is performed, the information that is thinned out and not displayed may be displayed when the display area is narrowed and the detailed map is displayed. When it is determined in (S204) that there is thinned information, the time stamp of the thinned information is (S201) or (S20).
Deleted from the time stamps searched in 3) (S20
5; do not delete from memory 22), end the information extraction work, and return to the flowchart shown in FIG.

Next, it is judged whether or not the displayed map is arbitrarily scrolled (S102). That is, it is determined whether or not the map is fixedly displayed. If it is fixedly displayed, it is determined whether or not route guidance of the vehicle is currently being performed (S103).
When the route guidance is not performed, that is, when the information of the specific route is not requested, the comprehensive display of the time stamp searched in (S101) is performed (S104). This comprehensive display collectively displays the upper limit value and the lower limit value of the time stamps searched in (S101). For example, the oldest one of the plurality of searched time stamps is AM10:
00 is information, most new information is AM10: If 30 of <br/> is also of a comprehensive display of the time stamp is AM1
It is performed like 0:00 to 10:30. FIG. 4 (a),
FIG. 4B is an example of the comprehensive display 27 displayed on the display unit 16. FIG. 4A shows the congestion information (indicates the congestion position and the length of the congestion) indicated by arrows 28a to 28d and the P mark 30.
It indicates that the parking lot availability information indicated by a and 30b and the construction information indicated by the cross mark 32 are all information generated at 10:00 am. Further, FIG. 4B shows that the traffic jam information, the construction information, and the like are information generated between 10:00 and 10:30 am. The own vehicle is indicated by arrow 3 in the figure.
4 is shown. In this way, the visibility of the display unit 16 is improved by displaying the comprehensive information instead of displaying the time stamp for each information.

Further, in the flow chart of FIG.
When the type of information displayed in 0) is limited by the input from the input unit 18 (information type designating means), for example, when only the traffic congestion information is requested to be displayed, the traffic congestion information as shown in FIG. Display other than is deleted or dashed line display (not shown)
Then, the comprehensive display 27 of the time stamps regarding the traffic jam information of the arrows 28a to 28g "AM 10:00 to 10:20".
Is done.

By comprehensively displaying the time stamps in this manner, the time stamps displayed on the display unit 16 are simplified and organized, and the substantive portion of the information and the visibility of the time stamps are improved. In particular, the visibility can be further improved by limiting the type of information to be displayed and displaying only the necessary information.

In addition, regardless of whether or not route guidance is being performed in (S103), the direction sensor 26a indicates the traveling direction of the host vehicle.
The information behind the host vehicle may be deleted by recognition (see FIG. 1), and the time stamps of information existing in the traveling direction may be comprehensively displayed. By performing such a display, the information of only the traveling direction of the own vehicle, which is highly important, is displayed, the information is organized, and the visibility of the substantial part of the information and the time stamp is improved.

When it is determined in (S102) that the map is being scrolled arbitrarily, a mark indicating information (arrows 28a to 28g indicating traffic congestion information or a parking lot vacant space) indicating information at a specific position of the display area, for example, the center. P mark 30 indicating information
a, 30b) is determined (S1).
05). The map is scrolled by the input unit 18. The input unit 18 may be a touch panel system that can be operated by touching the display unit 16 or a system using an independent switch. If there is no mark at a specific position,
Similar to the above, it is determined whether or not the route guidance is being performed in (S103), and the comprehensive display of the time stamp is performed.
When the mark is present, as shown in FIG. 6, the time stamp of the information at the specific position (in this case, the center) and the detailed information are individually displayed as necessary. In the case of Fig. 6, the map is scrolled and the cross mark 32 indicates the construction at the center position.
Exists. Therefore, the time AM1 when this information was generated
0:00 and detailed display 29 "Construction, one side traffic 10: 00-00
"12:00" is displayed on a part of the display unit 16 (S10).
6). In this case, since information other than the specific position, such as traffic jam information, is also displayed, even if the processing of (S104) is performed and the comprehensive display 27 of the time stamps is displayed in the same manner as in FIGS. 4 and 5. Good. In this way, by individually displaying the detailed information 29 on the information on the specific position, it is possible to obtain the necessary details of the information while improving the time stamp visibility of the entire received information. The specific position is not limited to the center and may be the right corner or the left corner of the map.

When it is determined in (S103) that route guidance is being performed by the GPS navigation system, it is determined whether or not the current position of the vehicle is on the route (S10).
7). When the vehicle is present on the route and the route guidance is performed well, the comprehensive display 27 of the time stamps regarding the information on the route is performed as shown in FIG. 7A. In this case, the time stamp of only the traffic congestion information arrow 28c and the parking lot information P mark 30a is comprehensively displayed as "AM 10:00 to 10:10" (S108), and the arrow 28c is also displayed on the map.
Only the P mark 30a is displayed as a solid line. Information other than the route may be deleted from the map, or may be indicated by a broken line as shown in FIG. If the information of the broken line portion is necessary, as described above (S102, S105,
The mark may be scrolled to a specific position as in S106) to obtain the time stamp of the desired information or the detailed display 29.

When it is determined in (S107) that the current position of the vehicle is not on the predetermined route, it is determined whether or not the vehicle is clearly off the route (S109). This is because the departure from the route may be due to a simple break or shopping. In this case, if the user has left the route for a predetermined time or more, or has passed a predetermined distance or more, it is considered that the route has been clearly left, and the comprehensive display is also displayed together with the time stamps related to the information other than the route. With
The substantial part of the information is displayed (S104). Also, if it is within a predetermined time or within a predetermined distance after leaving the route, it is determined that the movement based on the route guidance is restarted, and the comprehensive display of the time stamp of the information on the route is performed ( S108).

When the map is enlarged and displayed, as a result of wide area display, information that has been thinned out, that is, when the target is a short range such as traffic jam information or construction information, information (congestion information The arrow 28h) may be restored. In this case, if the display length of the restored information, particularly the traffic jam information, etc. on the display map exceeds a predetermined length (for example, 5 mm), it is determined that there is no information thinned out in the flowchart (S204) of FIG. , Arrow 28h (AM10:
15 information) and the comprehensive display 27 displayed in (S108) is indicated by an arrow 28 as shown in FIG. 7B.
It becomes like “AM 10:00 to 10:15” in consideration of h.

In this embodiment, the presence / absence of a limitation depending on the type of information is determined in (S200) to (S201) of the flowchart of FIG. 3, but the limitation may be added depending on the time of the time stamp, for example. In this case, "AM10:
The time range such as "00" or "AM 10: 00-10: 15" is limited, and the time stamps belonging to the range are searched. By performing such a limitation, the information in the desired time zone is organized, and the visibility of the substantial part of the information and the time stamp is improved.
