Seatbelt reminder system
View Patent ↗A seatbelt reminder system warns a crew member when the crew member has not fastened a seatbelt. The system makes a way of giving a reminder different between a case (S 302 , S 303 , or S 304 ) where the running state of a vehicle is detected when the unfastened state of the seatbelt is detected and a case (S 310 , S 311 , or S 312 ) where the unfastened state of the seatbelt is detected when the running state of the vehicle is detected.
1. A seatbelt reminder system for outputting a reminder for an occupant when the occupant leaves a seatbelt unfastened, comprising:
a seat-belt fastening detecting element which detects a fastened state of said seatbelt;
a running-state detecting element which detects a running state of a vehicle; and
a reminder element which gives a reminder when an unfastened state of said seatbelt and said running state of said vehicle are detected from results of detection by said seat-belt fastening detecting element and said running-state detecting element, and makes a way of giving said reminder different between a case where said running state of said vehicle is detected while said unfastened state of said seatbelt is being detected and a case where said unfastened state of said seatbelt is detected while said running state of said vehicle is being detected,
wherein said reminder element delays start of said reminder for a predetermined period of time from a time when the detected fastened state of said seatbelt changes from a fastened state to said unfastened state while said running state of said vehicle is being detected as compared with that in said case where said running state of said vehicle is detected while said unfastened state of said seatbelt is being detected.
2. The seatbelt reminder system according to claim 1 , wherein said reminder element makes delay of start of said reminder different according to occupant's seats.
3. The seatbelt reminder system according to claim 2 , wherein a period of delaying start of said reminder for a driver's seat is set smaller than a period of delaying start of said reminder for other occupant's seats.
4. The seatbelt reminder system according to claim 1 , wherein said running-state detecting element detects said running state of said vehicle according to at least one of a vehicle speed, a transmission gear position and a transmission range position.
5. The seat belt reminder system according to claim 1 , wherein said reminder element enables re-reminding when halting of said vehicle is detected after said reminder is ended, and gives a reminder when said unfastened state of said seatbelt and said running state of said vehicle are detected.
6. A seatbelt reminder system for outputting a reminder for an occupant when the occupant leaves a seatbelt unfastened, comprising:
a seat-belt fastening detecting element which detects a fastened state of said seatbelt;
a running-state detecting element which detects a running state of a vehicle; and
a reminder element which gives a reminder when an unfastened state of said seatbelt and said running state of said vehicle are detected from results of detection by said seat-belt fastening detecting element and said running-state detecting element, and makes a way of giving said reminder different between a case where said running state of said vehicle is detected when said unfastened state of said seatbelt is detected and a case where said unfastened state of said seatbelt is detected when said running state of said vehicle is detected,
wherein said reminder element enhances contents of said reminder in said case where said running state of said vehicle is detected when said unfastened state of said seatbelt is detected as compared with those in said case where said unfastened state of said seatbelt is detected when said running state of said vehicle is detected.
7. A seatbelt reminder method for outputting a reminder for an occupant when the occupant leaves a seat belt unfastened, comprising:
detecting a fastened state of said seatbelt;
detecting a running state of a vehicle;
giving a reminder when an unfastened state of said seatbelt and said running state of said vehicle are detected; and
making a way of giving said reminder different between a case where said running state of said vehicle is detected while said unfastened state of said seatbelt is being detected and a case where said unfastened state of said seatbelt is detected while said running state of said vehicle is being detected,
wherein said making step includes the step of delaying start of said reminder for a predetermined period of time from a time when the detected fastened state of said seatbelt changes from a fastened state to said unfastened state while said running state of said vehicle is being detected as compared with that in said case where said running state of said vehicle is detected while said unfastened state of said seatbelt is being detected.
8. The seatbelt reminder method according to claim 7 , wherein delay of start of said reminder is made different according to occupant's seats.
9. The seatbelt reminder system according to claim 7 , wherein contents of said reminder are enhanced in said case where said running state of said vehicle is detected when said unfastened state of said seatbelt is detected as compared with those in said case where said unfastened state of said seatbelt is detected when said running state of said vehicle is detected.
