AI Technical Summary

Technical Problem

Existing vehicle water-floating airbag systems cannot effectively match the buoyancy distribution with the vehicle's center of gravity when the vehicle falls into water, causing the vehicle to lose balance and posing a risk of false triggering and economic loss.

Method used

By placing airbags at multiple locations on the vehicle and using wading depth and ground clearance sensors to detect the vehicle's status, the inflation volume of each airbag is adjusted to match the buoyancy distribution. Combined with vehicle attitude sensors and inflation devices, the vehicle can maintain balance on the water surface.

Benefits of technology

It effectively prevents vehicles from taking on water or sinking, ensures the safety of people inside the vehicle, reduces accidental triggering, and improves the stability and safety of vehicles when wading through water.

Abstract

A floating airbag system, a control method, an electronic device, a vehicle, and a storage medium. The floating airbag system is adapted to be arranged in a vehicle, and comprises: a plurality of airbags, a wading sensor, and an inflation device. The plurality of airbags are respectively arranged at a plurality of positions of the vehicle; the wading sensor is configured to detect the wading state of the vehicle; and the inflation device is configured to inflate, when the wading state of the vehicle satisfies a wading condition, at least one of the plurality of airbags, and adjust the inflation amount of the plurality of airbags to keep the vehicle balanced.
