[Problem that the invention attempts to solve]

Since the display screen of an in-vehicle display device is small, the conventional method described above can be used to It is difficult to place the cursor in a specific location, especially when the desired facility is located in a small space. It has a drawback that it is impossible to distinguish when there are a large number of

0004 This idea was made in view of the above points, and its purpose is is used when selecting a map that includes a specific address or when searching for information about a specific location. To provide an in-vehicle electronic map display device that allows you to enter a specific address by typing. be.

[0005]

[Means to solve the problem]

The in-vehicle electronic map display device of this invention is capable of storing data from a recording medium that records map information. A recording medium reading device that reads data, a vehicle position detection device, a map screen, and a vehicle position detection device. A video processing device that displays the position, an input device, and a main controller that controls the whole thing. In an in-vehicle electronic map display device consisting of a You can also display a given address on a map, or find a specific location on a map. When obtaining service information, enter the address by selecting characters by operating the screen using the input device. The system is configured to input information and display the obtained information.

[0006]

[Effect]

According to the in-vehicle electronic map display device of this invention, when searching for information on a specific location, You can specify the location on the map by entering the address by entering characters in the Even if many facilities are concentrated, a specific location can be easily specified without error.

【Example】

An in-vehicle electronic map display device that is an embodiment of this invention will be described based on the drawings. Figure 1 is a block diagram showing the configuration of an in-vehicle electronic map display device that is an embodiment of this invention. It is. In the figure, 1 is a video processing device, and a graphic controller 1a The image information is developed and stored on the video RAM 1c, and the video RAM The data stored in 1c is converted into a video signal by the graphic controller 1a. The image data is converted into an image and displayed as an image on a display device 1b such as a CRT or LCD. 2 is CD- A recording medium reading device consisting of a ROM driver, and a recording medium reading device consisting of a CD-ROM driver. Map information is read from the diagram database 2a. 3: remote control, light pen, touch It is an input device such as a switch. 4 is the own vehicle position detection device, which detects the global position. A GPS receiver 4b that receives radio waves from satellites of the navigation system and a direction sensor. The position of the vehicle is calculated from sensors 4c such as sensors and vehicle speed sensors, and their output signals. It is composed of an own vehicle position calculation device 4a. 5 is the main control that controls the whole thing It is.

[0008] Next, the operation of the embodiment will be explained with reference to the flowchart of FIG. device is operational In this case, first, the system is initialized in step S1, and the map data is Load the parameters necessary for map drawing (map list, color information, etc.) from the base, and The period screen is displayed on the display device 1b. Next, proceed to step S2 and enter the desired address. Enter. To enter an address, move the cursor on the screen to the input device as shown in Figure 3(a). Select a character by moving it by operating position 3. Next, in step S3 Search for the map with the entered address and read it with the recording medium reading device 2. The main controller 5 processes the data output from the capture device 2 and creates graphics. The data is sent to the controller 1a. The graphic controller 1a receives the input signal. It is expanded and stored on the video RAM 1c as image data. Video RAM1c The data developed above is converted into a video signal by the graphic controller 1a. The signal is sent to the display device 1b together with a synchronization signal and displayed on the screen. Next, Proceed to step S4, and enter the desired address on the displayed map screen as shown in Figure 3(b). Display a symbol indicating the location of. Next, the process moves to step S5, and the input device 3 It is determined whether or not there is an address change input, and if there is an address change input, the step Step S2 is repeated, and if there is no address change input, the process moves to step S6. Ste In step S6, it is determined whether or not there is a service information display request input from the input device 3. If the service information display request is not input, step S5 is repeated and the service information display request is not input. If a service information display request is input, the process moves to S7. In step S7, the input It is determined whether there is service information for the address entered, and there is no service information. If so, step S5 is repeated, and if there is service information, the process moves to step S8. do. In step S8, a service menu similar to that shown in FIG. 4(a) is displayed on the screen. Select the desired service information with the cursor. Next, in step S9, Service data is displayed on the screen as shown in FIG. 3(c). Next, step S In step 10, it is determined whether or not there is a change in the service data from the input device 3. , if there is a change in the service data, step S8 is repeated and the service data is changed. If there is no change, the process moves to step S11. In step S11, the input device It is determined whether there is an address change from step 3, and if there is an address change, step S2 is repeated, and if there is no address change, the operation is terminated.
