AI Technical Summary

Technical Problem

Existing vehicle collision protection structures cannot be dynamically adjusted, resulting in excessive structural utilization in minor collisions and insufficient reinforcement in extreme collisions. Furthermore, they cannot achieve reconfigurable and balanced resource allocation in multi-point collision scenarios, affecting the lightweighting and safety of the entire vehicle.

Method used

Guide rails are arranged in the front and rear anti-collision beams and the side panels of the vehicle, and movable slider structures are configured. Through the collision prediction system and control system, the sliders are moved to the predicted positions to form local reinforcement structures according to the collision risk level, so as to realize the reconfigurability of structural resources and the on-demand allocation of protective capabilities.

Benefits of technology

Without significantly increasing the overall vehicle weight, it achieves differentiated enhanced response under different collision conditions, improves the overall vehicle safety performance and structural efficiency, and solves the problems of unadjustable stiffness and uneven resource utilization in traditional protective structures.

Abstract

The application provides an adaptive crash protection system and a control method for a vehicle. The adaptive crash protection system comprises a vehicle frame, a front crash beam arranged at the front of the vehicle frame, a rear crash beam arranged at the rear of the vehicle frame, and a vehicle body side wall arranged at the left and right sides of the vehicle frame. The front crash beam, the rear crash beam and the vehicle body side wall are each provided with a guide rail. Two sliding blocks are slidingly arranged in each guide rail. The sliding blocks can be adaptively moved to a predicted crash position of the vehicle frame along the guide rail. The two sliding blocks arranged in the same guide rail can be adaptively moved to the same position to completely overlap or partially overlap. By arranging the movable sliding block structure in each guide rail, the vehicle can maintain the lightweight structure feature in the normal driving state, and the sliding blocks can be moved to the predicted crash position to form a locally reinforced structure when there is a risk of collision. The new vehicle passive safety architecture of "structure resource reconfigurability" and "protection capability on-demand distribution" is realized, and the vehicle safety performance and structure efficiency are significantly improved.
