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.
