Vehicular intelligent collision assistant energy absorption structure and its using method

The invention discloses a vehicular intelligent collision assistant energy absorption structure, which comprises a radar, a processor, a damper and an energy absorption box which are arranged on a vehicle body; the radar is used for measuring the distance with a wall barrier; the damper is connected with the energy absorption box through a connecting plate, the damper, the connecting plate and theenergy absorption box are formed to be an energy absorption structure; the radar and the damper are connected with the processor in a controlling manner. Meanwhile, the invention discloses a using method of the vehicular intelligent collision assistant energy absorption structure. Specific the changing collision acceleration, the regional rigidity of the energy absorption structure can be changedso as to adapt to the waveform change of acceleration, greatly absorb energy and reduce the vehicular acceleration; thus passenger injury risk is further reduced. 本发明公开的是种车用智能碰撞辅助吸能结构，包括在车体上设置的雷达、处理器、阻尼器以及吸能盒，雷达用于测量与壁障之间的距离，阻
