Abstract

PURPOSE:To newly register map information on a new road, etc., which is not recorded into a map and to making a display matching the map thereafter automatically by registering new road information according to information from a position detector and reading it out. CONSTITUTION:A controller 2 which recognizes the current position of an automobile by a position detector 1 consisting of a vehicle speed sensor, an azimuth sensor, etc., reads the map of the corresponding area output of a map reader 3 and displays the map and a mark indicating the current position on a display device 4. If, however, there is the road which is not registered in the map and the automobile is on the road, a console panel 5 is operated to select new registration. As the automobile travels on the new road, the information on the new road is obtained according to the information from the position detector 1 and stored in a storage device 6. Then when this road is read out, the newly registered map information from the storage device 6 is displayed together over the map from the map reader 3.

2. Description of the Related Art FIG. 4 is a block diagram showing a conventional navigation device. In FIG. 4, 1 is a position detecting device including a GPS, a vehicle speed sensor and a direction sensor, and 2 is information from the position detecting device 1. A control device for controlling and 3
Is a map reading device for reading a predetermined map in response to an instruction from the control device 2, and 4 is a display device for displaying the map from the map reading device 3 and the position information from the position detecting device 1.

Next, the operation will be described. GPS (Grob
al Positioning System) or the position detection device 1 including a vehicle speed sensor, a direction sensor, etc., and the control device 2 that recognizes the position of the traveling own vehicle C
Reading from the map reading device 3 using D, etc., and displaying device 4
A map and a mark indicating the current position of the vehicle are displayed.

[0004]

Since the conventional navigation device is constructed as described above, it is impossible to correct the map. For example, when a new road is created, a discrepancy occurs with the map. There was a problem that smooth navigation was not possible.

The present invention has been made to solve the above problems, and an object thereof is to obtain a navigation device capable of newly registering, storing and reading out map information such as new roads which are not on the map. And

[0006]

A navigation device according to the present invention includes a position detecting device including a vehicle speed sensor, a direction sensor, and the like, a control device controlled based on information from the position detecting device, and a control device. A map reading device for reading out a map in accordance with an instruction from the display device, a display device for displaying the map from the map reading device and the position information from the position detecting device, and an operation plate for instructing the control device about the control content, A storage device for registering and reading new road information based on information from the position detecting device is provided.

[0007]

In the navigation device according to the present invention, when the road on which the vehicle is traveling is a new road that is not on the map, the road is registered in the storage device based on the information from the position detection device and the new road is stored in the storage device. The read data will be displayed according to the conventional map.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a block diagram of a navigation device,
Reference numeral 1 denotes a position detecting device including a GPS, a vehicle speed sensor, an azimuth sensor, and the like, 2 denotes a control device that performs control based on information from the position detecting device 1, and 3 denotes a predetermined map according to an instruction from the control device 2. A map reading device for reading 4, a display device for displaying a map from the map reading device 3 and position information from the position detecting device 5, an operation plate for instructing control contents to the control device 2, and 6 for the control device 2. Is a storage device that can store and read new road information from.

FIG. 2 shows a display example of the display device 4, where the dotted road 4a is not registered, the road 4b is registered on the map, and the reference numeral 4c is the current position of the vehicle.

Next, the operation will be described. The control device 2 which has recognized the current position of the own vehicle by the position detection device 1 including a GPS, a vehicle speed sensor, a direction sensor, etc. reads a map of the corresponding area from the map reading device 3 using a CD or the like, and displays it on the display device 4. A map and a mark indicating the current position of the vehicle are displayed.

However, the road 4a not registered in the map
When the vehicle is located on the road 4a, the display screen is as shown in FIG. 2, and the vehicle is located on a place other than the unregistered road. At this time, the operation panel 5 is operated to select new registration. As the vehicle moves on the new road 4a, the map information about the new road 4a is obtained from the information from the position detection device 1. This can be stored in the storage device 6.

When this map is read next time, the newly registered map information from the storage device 6 can be displayed together with the map from the map reading device 3 superimposed.

In the above embodiment, when a new road is registered, the operation plate 5 is operated to select the new registration. However, since the operation is complicated and may hinder the driving of the vehicle, the embodiment shown in FIG. By adding an alarm 7 such as a buzzer as shown in FIG. 6 and activating the alarm 7 when the vehicle deviates from the road 4a registered on the map, the driver is informed that he is on an unregistered road and a predetermined If new registration of a new road is automatically started when the vehicle is separated from the registered road 4a by time or a predetermined distance, the operation is easy and the driving is not disturbed.

[0014]

As described above, according to the present invention, since a storage device capable of registering and reading new road information is provided in the conventional navigation device, a new road can be registered. It enables highly reliable navigation, eliminates the need to revise the map every time a new road is created, and makes the device inexpensive.
