There is a manual mode, which can be selected arbitrarily. In the auto mode, when the current position approaches a guide information point, guidance is given on the screen of the TV 6 and with the sound of the speaker 7.In the index mode, a list of guide information points is displayed on the screen of the TV 6, and the guide information point is displayed on the screen of the TV 6. Information will be provided on the screen and by audio. Further, in the manual mode, information on a guide point specified on a map displayed on the screen of the television 6 by a cursor or the like is provided on the television screen and by voice.

The operation will be explained below with reference to a flowchart.

Now, in the driving guide system 1, the map switch of the television 6 is selected, and map information as shown in FIG. 2 is displayed on the television 6.
It is assumed that the current position of the vehicle is displayed on the map screen as shown by a symbol and that the vehicle is traveling in the direction of the arrow. It is assumed that there are, for example, Higashiyama Zoological and Botanical Garden, Tsurumai Park, Nagoya-style Museum, etc. in this vicinity.

The guide information mode is selected by operating the touch panel switch 6a of the television 6 (step 1 in FIG. 4).
), for example, assume that auto mode (step 2) is selected. When this auto mode is selected, the computer 4 determines that the current position of the vehicle (7) and tourist guide information points, for example, the distance from the current position to the nearest Higashiyama Zoo and Botanical Garden, are within a predetermined distance, for example 1 km or less. It is determined whether or not (step 3). Computer 4 is
If the determination answer in step 3 is negative (No), this determination is repeated. Then, when the vehicle approaches within 1 km of Higashiyama Zoo and Botanical Garden and the determination answer in step 3 is affirmative (YES), the computer 4 displays guide information regarding the Higashiyama Zoo and Botanical Garden on the screen of the television 6 and also displays the guide information on the speaker 7. As soon as the guide information is announced (step 4), the process proceeds to the next step 5, and it is determined whether or not the guide information concerned is to be canceled.
