Problems solved by technology

However, the study found that because the conventional occupant restraint system is an airbag designed according to the normal position of a tall male, the detonation time and inflation intensity of the airbag thus designed may cause injury to women and children of small stature. The deployment of the airbag seriously injures the occupant more than the occupant who maintains the correct sitting posture

Abstract

The invention discloses an automotive airbag unfolding control system, an airbag system and an automobile. The airbag unfolding control system comprises a detection module, a calculation module, a main control module and an execution module. The detection module is used for outputting a pressure distribution signal, an automobile body collision pressure signal and an automobile speed signal; the calculation module calculates occupant types according to the pressure distribution signal, obtains a collision working condition in collision according to the automobile body collision pressure signal and the automobile speed signal and outputs an airbag unfolding command, an airbag opening level, a secondary ignition moment and an airbag exhaust amount according to the occupant types and the collision working condition; the main control module outputs airbag parameters to the execution module according to the airbag unfolding command, the airbag opening level, the secondary ignition moment and the airbag exhaust amount; the execution module controls an airbag of the automobile to be unfolded according to the airbag parameters. The automotive airbag unfolding control system can effectively reduce damage to small-stature women and children.

Description

technical field [0001] The present application relates to the technical field of automobiles, and more specifically, relates to an airbag deployment control system of an automobile, an airbag system and an automobile. Background technique [0002] Airbags have received widespread attention because of their good protection to occupants and the effective reduction of accident injuries. However, the study found that since the conventional occupant restraint system is an airbag designed according to the normal position of a tall male, the detonation time and inflation intensity of the airbag thus designed may cause injury to women and children of small stature. The deployment of the airbag seriously outweighs the occupant who maintains the correct sitting posture. Therefore, it is of great significance to effectively reduce the injuries of women and children of small stature due to the deployment of airbags according to different types of occupants.
