Seatbelt fastening state display device
View Patent ↗A microcomputer performs communication in conformity with the CAN standards to capture seating signals detected by seating sensors and seatbelt fastening signals by buckle switches. If determining from the captured seating signals that there is an unoccupied seat, the microcomputer displays a seatbelt state image at the unoccupied seat position in a vehicle image in gray presentation. If determining that there is an occupied and non-fastened seat, the microcomputer displays the seatbelt state image at the non-fastened seat position in the vehicle image in red presentation and displays the seatbelt state image at an occupied and fastened seat position in black presentation.
1. A seatbelt fastening state display device comprising:
a seating detecting unit configured to detect whether an occupant sits on a seat;
a fastening detecting unit configured to detect whether a seatbelt provided in the seat is fastened;
a display unit configured to display various kinds of information; and
a control unit configured to control contents of display on the display unit, wherein
the control unit causes the display unit to display a plurality of seatbelt state images depending on a state of the seatbelt, such that a first seatbelt state image is displayed when the seating detecting unit does not detect seating, a second seatbelt state image is displayed when the seating detecting unit detects seating and the fastening detecting unit does not detect fastening of the seatbelt, and a third seatbelt state image is displayed when the seating detecting unit detects seating and the fastening detecting unit detects fastening of the seatbelt.
2. The seatbelt fastening state display device according to claim 1 , wherein
the control unit causes the display unit to display a vehicle image depicting a vehicle as information indicative of the state of the seatbelt, and to display one of the plurality of seatbelt state images in the vehicle image at a position corresponding to a position of the seat.
3. The seatbelt fastening state display device according to claim 2 , wherein
the first seatbelt state image is displayed in a color with a lower degree of impression than the third seatbelt state image, and
the second seatbelt state image is displayed in a color with a higher degree of impression than the first and third seatbelt state images.
4. The seatbelt fastening state display device according to claim 2 , wherein
the control unit causes each of the plurality of seatbelt state images to be displayed such that an image depicting a seatbelt overlaps an image depicting an occupant and the image depicting a seatbelt is changed in color between the second state and the third state.
