Active child safety airbag device for school bus and control method thereof

Abstract

The invention provides an active child safety airbag device for a school bus and a control method thereof. The device comprises an airbag system, an ECU, a main switch, a pressure distribution sensor and a vehicle speed sensor, wherein the main switch, the pressure distribution sensor and the vehicle speed sensor are respectively connected with the ECU, the pressure distribution sensor is arranged on a seat, the airbag system comprises an airbag woven bag, an air supply device, a containing device, an air inlet control valve, an air release control valve and an air pressure sensor, the air inlet control valve, the air release control valve and the air pressure sensor are connected with the ECU, the air inlet control valve is communicated with the airbag woven bag and the air supply device, the air release control valve is communicated with the airbag woven bag and an air exhaust pipeline, the containing device is arranged on the back face of a seat back, and the air pressure sensor is arranged in the airbag woven bag. The device judges whether the airbag system works or not, judges the unfolding opportunity of the airbag woven bag, adjusts the pressure inside the airbag woven bag and provides best protection for child passengers through the sensors and the ECU. The airbag woven bag can be repeatedly used, impact damage and burning in detonation can be eliminated, the environment can not be polluted, and the device is suitable for the school bus, a passenger car and a car.

Description

technical field [0001] The invention belongs to the field of automobile safety, in particular to an active child safety airbag device for a school bus and a control method thereof. Background technique [0002] With the growth of car ownership, the number of road traffic accidents and casualties continues to increase. Among them, school bus accidents occur frequently. There are great potential safety hazards in school bus safety, which has become a social problem that plagues people today. [0003] The structure of the occupant restraint system of the current school bus has deficiencies. In working conditions such as frontal collision or emergency braking, the only system components that can play a role are the seat, safety belt, and front seat. Most of the school buses are equipped with the two-point lap belt seat belt specified in the "Seat Belt and Restraint System for Adult Motor Vehicle Passengers" in accordance with the "Special School Bus Safety Technical Conditions...

AI Technical Summary

Problems solved by technology

The main reason for the excessive injury of the 5th percentile dummy on the primary and secondary school bus is that the head injury is too high. There are various shapes on the seat, and it is difficult for adult seat belts to provide comprehensive protection

There are many types of actual school bus accidents, and there are many examples of rollovers. The traditional simple seat belt restraint system cannot meet the protection requirements of child occupants under these working conditions.

[0005] At present, the research on improving the safety of school buses at home and abroad is mainly aimed at strengthening the structure of the school bus itself, using driver assistance systems, intelligent driving systems, and the use of Internet of Vehicles, and further standardizing the positioning and operation of school buses by strengthening legal management. School bus occupant restraint systems are not optimized
