Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in a travel guidance device that displays a map on a display disposed in a vehicle interior to guide the travel of a vehicle.

(Prior art) Conventionally, this l! As disclosed in, for example, Japanese Unexamined Patent Application Publication No. Sho B7-144589, a travel guidance device for one vehicle includes a figure storage section that stores figures such as a map to be displayed on the display screen of a display device, and A device that is equipped with a character storage section that stores characters or symbols to be displayed and their positions on the graphics, and is configured to display the graphics in the graphics storage section and the characters, etc. in the character storage section in a composite manner on a display device. Are known.

By the way, by using the concept of the above conventional example, when a vehicle is in an abnormal state, emergency telephones needed for repair, such as at a dealer (vehicle shop), gas station, or on a motorway, can be set up. By storing the symbols represented and their locations on the map in the character memory, and displaying the symbols from the character memory in a composite manner on the map displayed on the display, the vehicle can be repaired in the event of a vehicle abnormality. One idea would be to be able to quickly guide people to places where they can.

However, in that case, symbols such as places where the vehicle can be repaired are always displayed on the map on the display, which makes the display content complicated, and when the vehicle is in normal condition, it is rather difficult to guide the vehicle. There is a problem that the original map needed for the map becomes difficult to see.

(Object of the Invention) The present invention has been made in view of the above-mentioned problems, and its purpose is to synthetically display symbols such as locations where the vehicle can be repaired on the map of the display only when the vehicle is in an abnormal state. By doing so, we can ensure good visibility of the map displayed on the display when the vehicle is operating normally, allowing the vehicle to be guided in a stable manner, while also providing a location where the vehicle can be repaired in the event of an abnormality. The purpose is to enable automatic identification and quick processing of vehicle abnormalities.

(Structure of the Invention) In order to achieve the above object, as shown in FIG. An abnormality detection means 2 that detects with a device or the like, a map storage section 8 that stores a map to be displayed on the display 1, and a vehicle current position calculation section 3 that calculates the current position of the vehicle using the vehicle speed sensor 4 and the direction sensor 5. , a symbol storage unit 9 that stores symbols of dealers, gas stations, etc., which are required in the event of a vehicle abnormality and are displayed on the map displayed on the display 1, and the positions of the symbols on the map; and the vehicle current position calculation unit. When receiving the output signal from the abnormality detection means 2, the map corresponding to the current position of the vehicle is read out from the map storage section 8 and displayed on the display 1. The apparatus is equipped with a controller 10 that synthesizes and displays the symbols in the symbol storage section 9 on the map displayed on the display 1.

As a result, when the vehicle is in a normal state, only the map necessary for driving the vehicle is displayed on the display 1, and when the vehicle is in an abnormal state, this is detected by the abnormality detection means 2.
Symbols of places where vehicles can be repaired, such as dealers, gas stations, emergency telephones, etc., are displayed in a composite manner on the above map.

(Example) Hereinafter, an example of the present invention will be described in detail based on the concave curves shown in FIG. 2 and subsequent figures.

FIG. 2 shows the overall configuration of a vehicle travel guidance system according to an embodiment of the present invention, in which 1 is a CRT (
A display device consisting of a cathode ray tube), etc.
1 has a display screen 1a.

Reference numeral 2 denotes a self-diagnosis device that is installed in a vehicle and automatically diagnoses the condition of the vehicle. An abnormality detecting means for detecting abnormal conditions such as the above is configured.

Further, reference numeral 3 denotes a vehicle current position calculation unit that calculates the current position of the vehicle, and the vehicle current position calculation unit 3 includes a vehicle speed sensor 4 that detects the traveling speed of the vehicle, that is, the vehicle speed, and a vehicle speed sensor 4 that detects the traveling direction of the vehicle. Direction sensor 5 and vehicle speed sensor 4 J3
and a current position calculation device 6 which receives outputs from the direction sensor 5 and the direction sensor 5, determines the heading direction when the vehicle has traveled a predetermined distance, and sequentially calculates the current position of the vehicle.

Reference numeral 7 denotes a storage section for storing display contents displayed on the display device @1, and the storage section 7 is composed of a map storage device 8 and a symbol storage device 9, and the map storage device 8 is connected to the display device 1 This is to store the map to be displayed on the screen. On the other hand, the symbol storage device 9 displays information on the map displayed on the display device 1 regarding dealers, gas stations, emergency telephones on motorways, etc. that are necessary for repair when the vehicle is abnormal as described above. It stores symbols and their positions on a map.

Further, reference numeral 10 denotes a control device as a controller for controlling each of the above devices, and the control device 10 receives an output signal from the current position calculation device 6 of the vehicle current position calculation section 3, and receives an output signal from the current position calculation device 6 of the vehicle current position calculation section 3, and receives the output signal from the current position calculation device 6 of the vehicle current position calculation section 3. As shown in a) and (b), a map M on which one passage 1 (corresponding to the current position PO of the vehicle is drawn) is read out from the map storage device 8 of the storage section 7 and displayed on the display screen 1a of the display device 1. At the same time, when receiving an output signal (symbol indicating vehicle abnormality) from the self-diagnosis device 2, the map M displayed on the display screen 1a of the display device 1 as shown in FIG. It operates to display the symbols P+ + P+ + . . . in the symbol storage device 9 in a composite manner.

Next, the operation of the above embodiment will be explained along the control flowchart not shown in FIG. A determination is made as to whether the vehicle is present or not, and if this determination is No, the same step SI is repeated. In this state, as shown in FIG. 4(a), the vehicle current position calculation unit 3 calculates the vehicle current position
is calculated, and a map M corresponding to the current position Pa of the vehicle is read out from the map storage device 8 of the storage section 7 and displayed on the display device 1.
is displayed on the display screen 1a, and the display screen 1a
The current position Po of the vehicle is displayed on the map M displayed on the map M, and the map M and the current position of the vehicle! Vehicle travel guidance is performed by checking with aPo.

At this time, since only the map M necessary for driving the vehicle and the current position PO of the vehicle are displayed on the display screen 1a of the display device 1, the display contents on the display screen 1a are simplified and the occupants can Data necessary for vehicle travel can be easily viewed, and therefore vehicle travel guidance can be performed stably.
