Description

TECHNICAL FIELD The present invention relates to a travel information display device that displays map information of a vehicle.

(B) Conventional Technology In recent years, a vehicle traveling device that guides a vehicle to a desired position has been standardized and developed. According to such a device, the map of the traveling area, the route to the destination position, and the traveling position of the vehicle are displayed on the CRT display equipped in the vehicle, so that the driver can see the screen of the CRT display. The target position can be quickly reached by referring to. In such a device, the map information is stored in a compact disc for each region, and when the map is displayed, the map information of the designated region is read from the disc, reproduced, and drawn on the CRT screen.

In addition, the route to the target position is achieved by inputting the current position of the vehicle and the target position on the map drawn on the CRT screen by moving the cursor, and the device side responds to such input by both. Of the roads connecting the positions, the shortest one is selected and this road is displayed by, for example, changing the color. The traveling position of the vehicle at the time of guiding the vehicle is obtained by adding the traveling direction and the traveling distance to the current position input by the cursor movement by the direction sensor detecting the traveling direction of the vehicle and the distance sensor detecting the traveling distance of the vehicle. Therefore, it is obtained by updating the current position of the vehicle one by one.

In such a vehicle traveling device, the map information of the predetermined information is read from the disk as described above, but it is sometimes desired to add information serving as a driver's mark to the map information. is there. On the other hand, for example, Japanese Patent Laid-Open No.
In the device disclosed in Japanese Patent Laid-Open No. 293117 (G01C 21/00), the marker is moved on the screen displayed on the map so that the marker matches the desired map position, and the marker position is stored in the memory by the input means. In addition, the name of the position is input by operating the Japanese syllabary key.

(C) Problems to be Solved by the Invention However, in the above-mentioned conventional technique, there is a problem that a complicated operation such as movement of a marker and operation of a Japanese syllabary key is required when inputting the mark information. It is often the case that the driver wants to input the mark information when he / she finds the mark information while the vehicle is traveling, but if such a complicated operation is required, the mark information cannot be input at that moment. Therefore, the present invention is to provide a traveling information display device capable of inputting mark information even when the vehicle is traveling.

(D) Means for Solving the Problems In view of the above problems, the present invention provides a reproducing means for reading and reproducing map information from a storage medium, a current position detecting means for detecting a current position of a vehicle, the reproducing means and the current position. In a traveling information display device having a display means for displaying the map and the current position of the vehicle on the screen based on the information from the detection means,
Auxiliary storage means for storing the position information of the vehicle and the attribute of the point, and a position input for inputting the position information of the point to the auxiliary storage means based on the information from the current position detection means by the operation during traveling of the vehicle. It is characterized by comprising means and attribute input means for inputting the attribute of the inputted point by an operation after the input.

(E) Operation When the position input means is operated at a desired timing while the vehicle is traveling, the position of the vehicle at the time of operation is input to the auxiliary storage means based on the information of the current position detection means. Further, after this input, the attribute input means is operated to input the attribute of the position corresponding to the input position into the auxiliary storage means.

(F) Example Hereinafter, one example of the present invention will be described with reference to the drawings.

FIG. 1 is a circuit block diagram of the same embodiment. (1) is a microcomputer that controls each part,
(2) is a current position detection circuit for detecting the current position of the vehicle,
(3) is a reproduction circuit for reproducing map information from a compact disc, (4) is a display circuit for displaying a map or vehicle position on the screen, (5) is a location of a mark object such as a bookstore or a gas station, and Auxiliary storage circuit that stores attributes,
(6) is an input circuit for inputting the location and attributes to the auxiliary storage circuit (5) via the microcomputer (1), and (7) is a ROM storing the operation program of the microcomputer (1) and attribute information described later. is there.

FIG. 2 is a diagram showing a key operation unit of an input circuit provided on the front surface of the apparatus main body, for example. As shown in the figure, the key operation unit (8) has two function keys (9a) and (9b),
Numeric keys (10) from 1 to 9 are provided. Of the function keys, when the registration key (9a) is pressed, the attribute information shown in FIG. 3 (a) is displayed, and when the display key (9b) is pressed, the attribute information shown in FIG. 3 (b) is displayed. ) Is displayed on the screen via the display circuit (4).

Next, the operation of this embodiment will be described with reference to the flowcharts of FIGS. 4 and 5.

FIG. 4 is a flow chart defining the writing of the mark information. For example, it is assumed that the user approaches the "bookstore" while the vehicle is traveling. At this time, when writing this "bookstore" information on the map, the driver first has to press the registration key (9a) described above. When it is determined in step 1 that the registration key (9a) is pressed, the registration key (9a) is stored in the auxiliary storage circuit (5) based on the information from the current position detection circuit (2) in step 2.
The vehicle position at the time of operation is stored. Thus, when the input of the position information is completed, the registration menu shown in FIG. 3 (a) is displayed on the screen of the display circuit (4) in step 3.
The driver, looking at this screen, enters the number with the corresponding mark (that is, "3" in the case of "bookstore") using the number keys (10) (step 4), and the name of the mark is displayed. (Attribute information) It is stored in the auxiliary storage circuit (5) (step 5). Therefore, by the above operation, the position and the name (attribute) of the mark are stored in the auxiliary storage circuit (5).

FIG. 5 is a flow chart defining the reading of the mark. When reading the mark, first, the display key (9b) is pressed. In step 1, it is determined whether or not the display key (9b) is pressed. If YES, the display menu shown in FIG. 3 (b) is displayed on the screen of the display circuit (4) (step 2). . Next, the driver uses the number keys (10) to input the number (for example, "3" in the case of "bookstore") assigned to the required attribute from the display menu displayed on the screen. In response to this, this number is input circuit (6) in step 3.
