Problems solved by technology
Although it uses active disengagement technology to realize energy unloading and discloses self-explosive bolts, it only realizes the detachment of the engine gearbox, but does not realize the disengagement of other vehicle body load systems such as fuel and exhaust. Dependency Control Method Out of Combination with Assemblies
Self-explosive bolts with different positions and numbers of explosions under different collision degrees have not been realized, and maintenance economy cannot be taken into account

Embodiment Construction
[0023]The technical solutions of the present invention (including preferred technical solutions) will be further described below with reference to some of the preferred embodiments of the present invention. Obviously, the described embodiments are merely embodiments of the invention, not all of the embodiments. Based on the embodiments of the invention, all other embodiments obtained without creative labor have not made creative labor premises.
[0024]The present invention discloses a high-speed collision, the in-vehicle assembly active detachment method is disclosed, and the collision acceleration signal is determined whether or not a collision occurs; it is judged that the collision is acquired is a real-time collision speed V.s; Compare real-time collision speed VsAnd the theoretical collision speed of the corresponding combination of XXXWhen VXSX+1When the active disconnection, the Nth assembly is disconnected, X ≥ 1.
[0025]Preferably, the first atrial combination is detached from ...

The invention discloses a method for actively separating a vehicle-mounted assembly during high-speed collision, and the method comprises the steps: judging whether a collision happens or not and the collision severity degree based on a collision acceleration signal, and representing the collision severity degree by an equivalent collision speed Vs; comparing a collision speed Vs and a theoretical collision speed VX corresponding to separation of Xth assembly combination one by one, when Vs is larger than VX and smaller than VX+1, actively disconnecting the Xth assembly combination, X being larger than or equal to 1. According to the method, a correlation control method of collision degree and assembly separation combination is introduced, self-explosion type bolts at different positions and in different numbers are exploded under different collision degrees, separation of the assembly is accurately controlled, and harm of collision to passengers and vehicle maintenance economy after collision are both considered.
Description
Technical field[0001]The present invention discloses a high-speed collision method, which belongs to the automotive technology, and a high-speed collision is disclosed, and a vehicle assembly is actively detached.Background technique[0002]The heat dissipation system, cooling system, power system, transmission system, exhaust system, chassis, and car luggage racks, etc., the exhaust system, chassis, and car luggage racks, etc., to provide collision protection, 1 / 3 to 2 / 3 of the total preparation quality. These devices are rigidly attached to the body, and the kinetic energy is absorbed with the body in the crash, and the kinetic energy is absorbed by the body in a short time, increasing the burden burden on the body of the body; in the engine, gearbox, radiator, battery, etc. The structure also occupies the resistance space and adversely affects the safety of the vehicle.[0003]The vehicle assembly is actively detached from the technology, that is, the active disconnect connection is ...
