Vehicle collision safety protection system and method

Abstract

The invention discloses a vehicle collision safety protection system and method. The vehicle collision safety protection system comprises a central processing module, a safety auxiliary module, an air bag control module, an auxiliary air bag module, a driving control module and a chassis control module. By utilizing the system and the method, the collision occurrence probability and the direction can be more accurately judged; an identification blind area in the process of acquiring collision parameters by a contact sensor is avoided, and accidents that a passive safety system cannot work due to serious vehicle collision are reduced; when collision occurs, the vehicle chassis can be adjusted through the chassis control module, the vehicle body collision posture is changed, and the capacity of collision transmitted to a driver is reduced; through fusion of a main vehicle track and a moving obstacle track, rapidity, accuracy and robustness of likelihood intersection point calculation are improved. Through estimation of the intersection probability, the calculation amount about the moving obstacle is optimized; and measures for coping with different levels of collisions are refined, and the acceleration comfort and safety are compatible.

Description

technical field [0001] The invention belongs to the technical field of assisted driving, and in particular relates to a vehicle collision safety protection system and method. Background technique [0002] With the evolution of smart car technology, the equipment rate of smart products in cars is also increasing. While improving the level of vehicle intelligence, it also improves the convenience, reliability and safety of car driving. As the main passive safety system of the vehicle, the airbag module plays an important role in driving safety. It relies on high-precision acceleration sensors and sensitive contact determination elements around the body to detect and confirm the collision event, and ignite the corresponding circuit according to the collision orientation and energy level. However, due to the blind spot in the arrangement of the sensors and the influence of the body structure, the airbag restraint device cannot be ignited in some special azimuth collisions, which...

AI Technical Summary

Problems solved by technology

However, due to the blind spots in the arrangement of the sensors and the influence of the body structure, the airbag restraint device cannot be detonated in certain special orientation collisions, which brings danger to the life safety of the drivers and passengers.

In addition, the airbag module is a passive safety system, which cannot predict the collision trend and make an emergency response, so that it cannot avoid or reduce the loss caused by the collision event to the owner
