Abstract

PROBLEM TO BE SOLVED: To allow a user to register with ease a course information and such guide information as voice and still picture to a course guide system which guides a car to a cruising course. SOLUTION: In a center system 2 provided at a business branch 1, a course information 14 and a guide information 3 for a course are registered. Since a cruising business course can be registered or changed freely while a landscape still picture on a course and such guide information as voice for course in direction can be registered or modified freely, a detailed and accurate guide information is registered at such point on a course as an intersection which is easy to be mistaken. The information is integrated with a map data 4, which is stored in an on-vehicle system 7 set in a business car 6. The on-vehicle system 7 displays the registered course information 14, and when the business car 6 approaches a registered point in the guide information 3, such side information as landscape, image, and voice are outputted for guiding a driver. Since the center system 2 has the course information 14 and the guide information 3 registered, a travel simulation can be performed with the center system 2 in advance, so the driver fully know a course before driving the business car 6.

(First Embodiment) In a first embodiment of the present invention, route information and guide information such as a still image and audio are registered, and map data, route information and guide information are integrated. Is a route guidance system that includes a center device that creates a route and an in-vehicle device that performs route guidance and guidance based on map data.

FIG. 1 shows the configuration of a route guidance system according to a first embodiment of the present invention. In the center device 2 installed in the sales office 1, route information 14 and guidance information 3 such as still images and audio corresponding to the route are registered. The route / guidance information-map data integration means 5 uses the existing map data 4
And the route information 14 and the guide information 3 are integrated to create map data 13 in which the route / guide information is integrated. The created map data 13 is transmitted through a recording medium, a communication network, or the like.
It is stored in the in-vehicle device 7 installed in the commercial vehicle 6 and is used for route guidance / guidance. The recording medium is a magnetic disk or I
A C memory card can be used, and the communication network may be wireless or wired.

FIG. 2 shows an operation example of guidance / guidance of a vehicle-mounted device in the route guidance system according to the first embodiment of the present invention. The display 12 of the vehicle-mounted device 7 includes:
Registered route information 14 is displayed, and as the vehicle travels along the route in the order of A → B →... → F, a still image 8 of a landscape, a still image 10 of an image, and a sound 11 are registered in advance. Is output, and the driver is guided / guided on the operation route.

FIG. 3 shows a first example of the storage format of the guide information. Daytime scenery 17 and nighttime scenery 18 are registered for the same intersection G, and can be selected and used depending on the operation time. For example, it is set so that the daytime scenery 17 is displayed from 6:00 am to 6:00 pm, and the nighttime scenery 18 is displayed from 6:00 pm to 6:00 am. In addition, it is also possible to store, as guidance information, a season, weather, a landscape according to the driver's preference, and to select a desired landscape.

FIG. 4 shows a second example of the storage format of the guide information. The road distance 19 between the points where the guidance information is registered is registered and managed. For example, if the vehicle accidentally reaches point H after passing point B,
, It is possible to detect that the vehicle has not reached the point C even after traveling 100 m after passing the vehicle, and warn the driver that the vehicle is off the route. Further, by displaying the scenery of the point C, the driver can be confirmed to be off the route.

Further, as shown in FIG. 5, it is also possible to add a traveling direction mark 20 on a still image of a landscape to provide guide information. For example, when a still image of an intersection is registered in the center device 2, an arrow may be drawn on the still image in accordance with the route information.

FIG. 6 shows an operation example of the route simulation in the center device 2. Display of center equipment15
Then, a situation in which the vehicle runs from A to F on the route information 14 is simulated, and guidance information is output at each point. For example, assuming that the vehicle is traveling at a speed of 40 km / h, still images and sound corresponding to passing through points A to F are sequentially output. This route simulation makes it easy to confirm and store the traveling route.
Further, detailed and accurate guidance information can be additionally registered at an easily erroneous point on the route.

FIG. 7 shows an operation example 1 of the vehicle-mounted device when the vehicle deviates from the route. When it is detected that the vehicle position deviates from the route of the registered route information, the azimuth and the distance to the destination (or the next stopover or the point off the route) are displayed. Whether to return to the destination, the next stopover point, or a point off the route is set in advance according to the contents of the patrol work or the like.

FIG. 8 shows an operation example 2 of the vehicle-mounted apparatus when the vehicle deviates from the route. Here, a route that returns to the destination (or the next stopover or a point off the route) is shown. The return route is calculated by a method of finding the shortest route using the current vehicle position as a starting point and the return point as a destination.

It is also possible to switch between the operation example 1 of FIG. 7 and the operation example 2 of FIG. 8 according to the distance and time off the route. If the distance and time after leaving the route are short, only the information on the traveling direction and distance is easier to understand, and if the distance and time after leaving the route are long, the return route is specifically displayed Since it is easier to understand, it is advisable to set an appropriate distance and time and switch which is displayed.

As described above, in the first embodiment of the present invention, the route guidance system registers the route information and the guidance information such as still images and voices, and integrates the map data, the route information, and the guidance information.
