DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention shown in the drawings will be described below. In FIG. 1, an alarm system unit 1 includes a wakefulness detection unit and a driver fatigue detection unit in a driver's dozing prevention device mounted on a vehicle, and / or
An alarm transmission unit or the like in a signal monitoring device provided in conjunction with the navigation system. An alarm signal generated by the alarm system unit 1 is taken into the arithmetic unit 2, and a character stored in the data storage unit 3 according to the alarm signal. As will be described later, appropriate character information and guidance information are taken into the arithmetic unit 2 from the data section 3a and the guidance data section 3b, and the GPS 4 and the map data section 5 in the navigation system respectively provide GPS information.
The information and the map information are taken into the arithmetic device 2, and the information content determined by the arithmetic device 2 is presented to the driver of the vehicle in the form of an image and a sound from the image display device 6 and the sound output device 7, respectively.

The character data 3a in the data storage unit 3 stores a plurality of pieces of character information, for example, a plurality of preferable talent images and popular anime images. The driver selects a favorite character in advance. The character to be selected can be freely changed at any time, and information of one character selected by the driver is taken into the arithmetic unit 2.

The guidance data section 3b of the data storage section 3
(1) Indirect guidance for stopping a vehicle to allow a driver to take a break in response to a warning signal from a wakefulness detection unit or a driver's fatigue detection unit in a dozing prevention device. Information, such as the passenger's words, "I want to take a break soon,""I've been sitting down and my back has hurt.", "A little break?", "I want to breathe in the outside air.""Because there are many accidents in this area, be careful.", "There is a tourist spot near Kamakura.", "I want to go to the toilet, so please stop at the next parking lot." And other environmental information such as "Soon to be in the scenic spot.""Special products will be sold at the next parking lot.", "Special products will be sold to the roadside shops that are approaching soon.""," Next service Has been sold delicious lunch in the rear. "," Is on the following services Elijah There is a hot spring. "And the like and, (2) an alarm signal from the alarm transmission unit in the hotel's signal monitoring device to the navigation system,
For example, in response to an alarm signal that prompts the driver to start when the driver does not notice that the signal has turned green when stopping at a traffic light, indirect guidance information for prompting the driver to start, for example, The passengers said, "Let's go now.", "Let's depart soon.", "Let's go now.", Etc. (3) Warning that the amount of remaining fuel in the vehicle is running low In response to the signal, indirect guidance information to inform the driver that refueling is needed soon, e.g.
If you go 0m, you will find a gas station. And various guidance information such as "There is more than 10 km to the next gas station."

Next, the operation of the above device will be described.
During normal driving or the like, the GPS information and the map information taken into the arithmetic unit 2 from the GPS 4 and the map data unit 5 in the navigation system, respectively, and the character information stored in the character data unit 3a of the data storage unit 3 Based on the information of the character selected by the driver and taken into the arithmetic unit 2, a map and an image of the character as shown in FIG. Appropriate guidance information is presented from the device 7 in the form of audio.

However, when the alarm signal generated by the alarm system unit 1 is taken into the arithmetic unit 2, the guidance information corresponding to the alarm signal is obtained from various types of guidance information stored in the guidance data unit 3b of the data storage unit 3. For example, as shown in FIG. 3, as the passenger's words, the character information “I want to take a break soon.” And the character information stored in the character data portion 3 a of the data storage portion 3 are converted into the character information. At the same time, the image in which the character stretches the arm upward and takes a tired pose is presented from the image display device 6 to the driver, and at the same time, the "soon soon" of the same content as the character information with a tone suitable for the character. I want to take a break. "Is presented to the driver from the audio output device 7.

As for the combination of the character information and the voice information, only an appropriate type may be selected corresponding to one alarm signal, and the combination may be presented as appropriate. Then, a combination of a plurality of appropriate character information and voice information exemplified above are each randomly,
Alternatively, it is preferable that the information is continuously presented while being changed in an appropriate order, since the stimulus to the driver is further strengthened compared to the case where the same information is repeatedly presented. Are indirect guidance information, so that even if they are continuously presented, it is possible to easily suppress the driver from feeling annoying.

The image of the character presented from the image display device 6 has a pose appropriate for the combination of the character information and the voice information, for example, "I'm sitting down and my back hurts." For the guidance information of the fellow passenger, a pose such as tapping the hips bent by the character is selected, and for the guidance information of the fellow passenger, "Be careful because there are likely to be many accidents in this area." A pose in which the character looks around and around is selected. For guidance information such as "Special products are sold at the next parking lot," a pose in which the character is giving the special product is selected. In response to the passenger's guidance information, such as "Let's go now?", The character swings around his arm. 'S or the like is selected, "from now on 500
If you go m, you will find a gas station. Is assumed to be selected for the guidance information of "".

That is, when the alarm system unit 1 generates an alarm signal, appropriate guidance information corresponding to the alarm signal is text information and character image information from the image display device 6 and audio information from the audio output device 7. Are combined and presented to the driver at the same time, and all the guidance information is presented in an indirect expression that prompts the driver to take necessary actions. It is relatively easy to understand and can guide guidance information without any psychological resistance, so that the driver can easily guide the actions to be taken. There is a feature that makes it possible to effectively realize comfortable running.

Further, the alarm system 1 sets the threshold for generating an alarm signal to be relatively low, so that the presentation frequency of the guidance information as described above is relatively increased and the presentation of the guidance information is prevented from being omitted. Even in such a case, all of the guidance information is presented in an indirect expression and is easily accepted by the driver, so that it is possible to easily reduce the possibility that the presentation of the guidance information causes the driver to be troublesome.

In the above-described embodiment, the character information, the character image information, and the character information are provided as guidance information that indirectly expresses the actions to be taken by the driver in response to situations in which the driver should be alerted. Although three types of voice information are presented to the driver at the same time, depending on the case, one of them is omitted, or only one of them is presented to the driver as guidance information. Even if it does, the same operation and effect as the above embodiment can be obtained.
