Vehicular safety belt use reminding and forcing system and vehicular safety belt use reminding and forcing method

Abstract

A vehicular safety belt use reminding and forcing system comprises a safety belt buckle sensor, a seat weight sensor, a safety belt extension amount sensor, a light sensor, a control unit and a reminding and enforcing device, wherein the control unit is used for judging whether a driver and passengers are on seats or not according to borne weight of seat cushions, and judging whether the driver and the passengers wear safety belts or not according to the safety belt buckle state, the safety belt extension amount and the relation between the safety belt light intensity and in-vehicle reference light intensity. When judging that the driver and the passengers are on the seats but do not wear the safety belts, the control unit controls the reminding and enforcing device to be started so as to remind and force the driver and the passengers to wear the safety belts. The invention further provides a vehicular safety belt use reminding and forcing method. The system and the method are capable of urging the driver and the passengers to develop the habit of wearing the safety belts.

Description

technical field [0001] The present invention relates to a vehicle safety system and its usage method, in particular to a vehicle safety belt reminding and mandatory usage system and method.

Problems solved by technology

[0004] However, if the driver and occupant insert the dead bolt of the safety belt into the slot from behind or the driver and passenger find another safety belt and insert it into the slot of the safety belt of the seat, the existing vehicle safety belt The reminder and mandatory use system still judges that the seat belt is in the correct wearing state, and it is difficult to encourage drivers and passengers to develop the habit of wearing seat belts, which poses a major safety hazard
