[Detailed description of the invention]

The present invention is an in-vehicle map display device, in particular, which allows a user to freely select and register specific points that serve as landmarks for vehicle travel guidance, and provides optimal travel guidance for each user. Regarding -4. Traditionally, in-vehicle map display devices have been used to assist vehicles such as automobiles in driving, and in addition to maps such as roads, information on specific points that can be used as landmarks when driving (for example, schools, post offices, government offices, etc.) is displayed in advance. It is known that a device is prepared in advance and displays a mark or the like regarding the specific point on the display screen. However, this scale device normally places the above-mentioned 1JJ stomach point mark etc. on the displayed map in a fixed manner.414
Due to the large size of the map, there is a lack of flexibility, and some users may see singular points that are unnecessary, while other users may be missing singular points that are necessary due to map display capabilities, etc. Therefore, it could not be said that Yuri's driving guidance was fully achieved that was optimal for each individual.The present invention was made in view of the above points, and the

This will be explained with reference to the figures. Here, Figures 5 to 7 are diagrams for explaining the creation of the σ record candidate point file, Figures 8 to 13 are diagrams to explain the creation of the registration point file, and Figures 14 and 15. 16 is a diagram for explaining the registered point display, and FIG. 16 d3 and FIG. 17 are diagrams for explaining the effects of this embodiment. First, we will explain how to create a registration candidate point file. When the process for displaying the map on the CRT display 3 in the control device 7 is completed in accordance with the map display instructions etc. from the manual production section 5, the process shown in FIG. 5 is started. . In this process, step 101 is executed and singular point information P+, F2, Pa, . . . , pn, or article information S1, S2, S3, . , and set the individual point number i input to Sn to "1". After this initiallet, step 102 is executed to determine whether 1 is greater than a predetermined positive integer nJ. If the result of this determination is +-N OJ, step 103 is executed. In step 103, it is determined whether the singular point indicated by the singular point information Pi exists within the map display area of the CRT display 3. If it is determined that the singular point Pi exists within the map display area, then step 104 is executed and the singular point information P

Do the following. When the leftward movement cursor key 15 is operated, the process shown in FIG. 11 is started. In this processing, step 301 is first executed, and after processing is performed for increment 1 of J, step 302 is executed next, and it is determined whether or not j is larger than the river. If j is smaller than m, step 303 is executed next, and the map coordinates (X,
1° from the display coordinates (X, V) corresponding to Y)
The 'trj different point Ill buy mark' will be displayed in the map display area of CR Ding Disui 3, and the 'trj different point's name will be displayed.
CR1" Processing for displaying the name of the display 3) 25 is performed 41. The cursor key 15 for moving to the left after A is operated several times, and J becomes more obscure than M. Since the determination result of step 302 is reversed to rYEsJ, step 304 is executed next, J is set to [-1], and step/303 is executed. In other words, if J is thicker than m (then the singular point position mark and 1゛11 different place names for the σ record candidate point information ``1'' will be displayed.On the other hand, in Fig. 10 above) With the singular point position mark 23 and the singular point name displayed, when the crew member or the like decides that he or she wishes to register the singular point and operates the sera key 17, the system shown in FIG. 12 is displayed. In other words, the process of loading the contents of the registration candidate point information "j" into the RAM 7-5 is performed by executing step 401. Therefore, the RAM 7-5 has data as shown in FIG. Registered point information G1, G2,
G3, ..., G standing (9, is smaller than mouth 1),
