If the temperature inside the vehicle is high and uncomfortable, it is determined that there is a reasonable reason that the occupant has taken off or is about to take off the seat belt, and the process proceeds to the stop / warning mode in step 205. When the temperature inside the vehicle is not high and it is not uncomfortable, the process proceeds to step 203.

In step 203, the clock section 3c
Using the earliest recognition time α of the seatbelt as a start time, it is checked whether the seatbelt wearing time exceeds a predetermined time preset in the time setting device 8. If the time exceeds a predetermined time set in advance, it is determined that there is a reasonable reason that the occupant has taken off or is about to take off the seat belt, and the process proceeds to the stop / warning mode in step 205, If it does not exceed the predetermined time set in advance, step 206
To the seat belt wearing recovery mode.

In the seat belt wearing maintenance mode of step 204, the judgment unit 3b determines whether the occupant does not feel discomfort or resistance to wearing the vehicle or wearing the seat belt. It provides voice data and image data of a quiz, a game, a conversation, etc., and sends an instruction to the information transmitting device 4 to perform a handshake or a hug in a simulated manner.
In the stop / warning mode of step 205, the information transmission device 4 is instructed to give a recommendation to the driver to take a rest and to warn the occupant to wear a seat belt until the driver enters the break. Send. Note that the audio output unit 4
a transmits information to each of a driver and an occupant by a dedicated speaker.

In the seat belt wearing recovery mode of step 206, an instruction is sent to the information transmitting device 4 to issue a warning to stop the information transmission performed in the seat belt wearing maintaining mode, and then the information transmission is stopped. Step 207
Then, the storage unit 3a stores the information transmission contents performed in each of the above operation modes. At this time, the specific number is stored along with the information transmission contents and displayed on the display unit 10a.
In addition to this flow, the same content can be transmitted by setting the number of the favorite content with the number setting device 10 at any time.

In step 208, the judging unit 3b checks whether or not the accessory power supply of the vehicle has been turned off based on the information from the traveling state detecting device 2. Then, if it has been turned off, this flow is terminated, and if it has not been turned off, the flow returns to step 201 to repeat this flow.
