The invention relates to an active energy absorption structure capable of bearing oblique impact and a control method, the active energy absorption structure comprises a vehicle-mounted CAN network, a collision pre-judgment unit, a target motion state inspection unit, a target type identification unit, a front end energy absorption structure action unit and a front end energy absorption structure controller, and the front end energy absorption structure action unit comprises an actuator and an actuator power supply. The actuator is composed of two electromagnets wound with electromagnetic coils, the front end energy absorption structure controller comprises a front face collision folding crushing module and a side face collision folding crushing module of a front longitudinal beam, and the front face collision folding crushing module and the side face collision folding crushing module are both divided into a protection-needing object mode and a resistance-needing mode. The anti-collision device has the advantage that when a vehicle is collided, the mechanical characteristics of the impact bearing structure can be actively changed according to a collision scene. When the vehicle is obliquely impacted, the energy absorption box, the front longitudinal beam and the like can generate a stable crushing type so as to absorb more collision energy.

    本发明涉及一种可承受斜向冲击的主动吸能结构及控制方法,包括:车载CAN网络、碰撞预判单元、目标运动状态检查单元、目标类型识别单元、前端吸能结构动作单元和前端吸能结构控制器,前端吸能结构动作单元包括:动作器和动作器供电电源,动作器由两个缠绕有电磁线圈的电磁铁构成,前端吸能结构控制器包括前纵梁的正面碰撞折叠压溃模块和侧面碰撞折叠压溃模块,其中正面碰撞折叠压溃模块和侧面碰撞折叠压溃模块均分为需保护对象模式和需抵抗模式;本发明的优点是:可以使车辆在发生碰撞时,根据碰撞场景主动改变承受冲击结构的力学特点。当车辆受到斜向冲击时,可以使吸能盒及前纵梁等产生稳定的压溃型式,以吸收更多的碰撞能量。
