An album 3 index is stored in the album content of the wife sitting in the seat, and an album 4 index is stored in the album content of the husband sitting in the driver's seat.
[0057]
In the car navigation / car steering apparatus 1, the presence / absence of the output of the right rear seat sensor 6C is detected (p-9). In the car navigation / car steering device 1, when the seat sensor 6C detects that a child is sitting on the right rear seat, the contents recorded by automatically selecting the album 1 from the large-capacity information storage unit 12 are sequentially reproduced. (P-10). In the car navigation / car steering apparatus 1, when no child is sitting in the right rear seat and the output from the right rear seat sensor 6C is not detected, the presence / absence of the output of the left rear seat sensor 6D is detected (p-11). . In the car navigation / car steering apparatus 1, when the seat sensor 6D detects that a child is sitting in the left rear seat, the contents recorded by automatically selecting the album 2 from the large-capacity information storage unit 12 are sequentially reproduced. (P-12).
[0058]
In the car navigation / car steering apparatus 1, the presence or absence of the output of the passenger seat sensor 6B is detected when no child or the like is sitting in the rear seat and the outputs from the right rear seat sensor 6C and the left rear seat sensor 6D are not detected. (P-13). In the car navigation / car steering apparatus 1, when the seat sensor 6B detects that the wife is sitting on the passenger seat, the contents recorded by the album 3 being automatically selected from the large-capacity information storage unit 12 are sequentially reproduced. (P-14). In the car navigation / car steering device 1, when the output of the passenger seat sensor 6B is not detected, only the driver is in the vehicle and the contents recorded by automatically selecting the album 4 from the large-capacity information storage unit 12 are sequentially reproduced. (P-15).
[0059]
In the car navigation / car steering apparatus 1, when the reproduction operation of each album described above is ended or ended in the middle (p-16), the input operation unit 11 performs the end operation (p-17). Note that the playback operation of each album is automatically ended when another mode setting operation is performed by the input operation unit 11. In the car navigation / car steering apparatus 1, the driver's seat sensor 6A does not function when the album automatic reproduction operation is performed according to the above-described procedure. For example, when the priority order for each seat is set, the output of the driver's seat sensor 6A Of course, it is necessary when the top is.
[0060]
In the car navigation / car steering device 1, the priority order of the seat sensors 6 </ b> A to 6 </ b> D can be appropriately set by the input operation unit 11 as described above, and for example, the outputs of some seat sensors 6 are output. It can also be set to be invalid.
[0061]
In the car navigation / car steering apparatus 1, ranking is performed for each seat. However, as described above, a pressure sensor having specifications that allow the seat sensor 6 to adjust sensitivity or detect pressure is also used. The car navigation / car steering apparatus 1 measures the weight of a person sitting on a seat with a pressure sensor, and based on the measurement result, identifies whether it is an adult or a child, and priorities are set.
[0062]
In the car navigation / car steering apparatus 1, as described above, the reproduction control of the album for each passenger stored in the large-capacity information storage unit 12 is performed based on the output of the seat sensor 6 for identifying the passenger. It is not limited to such usage examples. In the car navigation / car steering apparatus 1, for example, when a child rides, a movie for children stored in the large-capacity information storage unit 12 can be automatically reproduced.
[0063]
【The invention's effect】
As described above in detail, according to the present invention, by providing the car navigation function and the car audio system function, it is possible to perform an efficient and comfortable driving that is not boring for the passenger. According to the present invention, at least a large amount of storage information consisting of map information, acoustic information and image information, and reproduction control information for controlling the reproduction order of these storage information are stored in the storage means having a large capacity information recording characteristic. In addition, each seat is provided with seat information detecting means for identifying the passenger and outputting the passenger information, and the reproduction processing means selects predetermined storage information from the storage means based on the passenger information and the reproduction control information. Thus, since the reproducing operation is performed, it is possible to select and reproduce optimum recording information from a large amount of stored information without the troublesome troublesome selection operation. According to the present invention, it is possible to sequentially view content suitable for children when driving with a family.
