Description

Vehicle collision safety control method and device, vehicle and storage medium Technical Field The present application relates to the field of vehicle technologies, and in particular, to a vehicle collision safety control method and apparatus, a vehicle, and a storage medium. Background At present, a safety belt and an air bag are the most effective protection measures for passive safety control in a vehicle collision accident, but in accident investigation, the safety belt and the air bag have larger limitations in serious collision accidents. In the related art, the passive safety control system only depends on 3-5 external acceleration sensors and pressure sensors, and the acceleration sensor arranged in the air bag controller is used for identifying whether a collision accident occurs or not, so as to judge whether corresponding control measures are needed to be executed. However, due to the limitation of the sensing capability of the related technology, the airbag is extremely easy to cause that the airbag cannot be normally ignited in partial collision accidents, and when the vehicle is seriously collided, the ejected airbag can shield the vision of drivers and passengers, so that the driver cannot timely unlock the safety belt, open the vehicle door or the vehicle window, and further cannot escape quickly. For example, a vehicle rollover accident generally does not cause obvious changes in vehicle body acceleration, so that acceleration data collected by an acceleration sensor arranged in an airbag controller does not meet airbag deployment conditions, and finally an airbag cannot be effectively ejected to protect safety of drivers and passengers, and the problem is to be solved. Disclosure of Invention The application provides a vehicle collision safety control method, a vehicle collision safety control device, a vehicle and a storage medium, which are used for solving the problems that the safety airbag cannot be normally exploded in partial collision accidents easily due to the limitation of the perception capability of the related technology, and the ejected safety airbag can shield the sight of a driver and cannot escape quickly when the vehicle collides seriously, and the survival and escape efficiency of the driver and the passenger are improved by improving the collision recognition precision, eliminating the interference of the safety airbag on escape.
