A kind of motor vehicle double air bag safety device and its control method

Abstract

The invention discloses a double airbag safety device for a motor vehicle and a control method thereof, comprising a seat system, an airbag system, several sensors, an infrared night vision camera, a main switch and an ECU; the seat system comprises a headrest, a headrest guide rod, Upper backrest frame, lower backrest frame, cushion frame, swing arm, upper round shaft, lower round shaft, transmission rod, short round shaft A, pedal, short round shaft B, spring, baffle, angle sensor, angular velocity sensor; The air bag system includes backrest air bag, headrest air bag, air supply device A, air supply device B, gas pressure sensor A, gas pressure sensor B, inflation valve A, deflation valve A, inflation valve B, deflation valve B, inflation tube Road A, deflated pipeline A, inflation pipeline B, deflated pipeline B. The ECU controls the air supply device A, the air supply device B, the inflation valve A, the deflation valve A, the inflation valve B, and the deflation valve B according to the detected vehicle information. The invention can minimize or avoid the injury of the occupant and can be used repeatedly.

Description

technical field [0001] The invention belongs to the field of occupant protection in motor vehicle safety devices, and in particular relates to a motor vehicle dual airbag safety device and a control method thereof for protecting the safety of rear occupants when the motor vehicle undergoes emergency braking or frontal collision. Background technique [0002] When emergency braking or frontal collision occurs in the motor vehicle, the rear occupants will rush forward under the action of inertial force. During this process, the heads of the rear occupants will hit the headrests and the upper part of the backrests of the front seats, causing the rear occupants to suffer varying degrees of injuries to their heads, necks, chests and other parts. In order to reduce the injury of the rear passengers, airbags are usually installed in the front seats, but due to the narrow space in the rear row, the instantaneous detonation of the traditional airbags will cause serious injury to the ...

Problems solved by technology

In order to reduce the injury of the rear passengers, airbags are usually installed in the front seats, but due to the narrow space in the rear row, the instantaneous detonation of the traditional airbags will cause serious injury to the rear passengers in the "off-position" sitting position; and the traditional safety The airbag can only be used once and cannot be reused, resulting in waste
