Vehicle active defense method, system and vehicle

Abstract

The invention discloses an active defense method and system for a vehicle and the vehicle. The active defense system comprises a personnel status detection module, a control module and an execution module, wherein the personnel status detection module is used for detecting the relative speed parameters of the heads, relative to the vehicle, of personnel in the vehicle and the relative displacementparameters of the heads, relative to the vehicle, of the personnel within a first preset time; the control module is used for pre-judging whether the personnel in the vehicle have a risk of collisionor not and predicting the parts which possibly have a collision according to the relative speed parameters and the relative displacement parameters; if there is the risk of collision through the prejudgment, according to the prejudged part which possibly has a collision, a corresponding control instruction is sent to the execution module; the execution module is used for responding to the controlinstruction and executing corresponding defense operation. By means of the technical scheme, according to the status of the personnel in the vehicle, active defense is conducted, no matter which collision way the vehicle is in, a good active defense effect can be obtained, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to a vehicle active defense method, system and vehicle. Background technique [0002] Car airbag is a commonly used passive safety protection device. When a car collision occurs, the airbag is detonated after the occupants of the vehicle collide with the airbag, thereby providing auxiliary safety protection for the occupants of the vehicle. However, the airbag itself also has certain limitations. Generally, whether the airbag is detonated has a lot to do with the angle at which it hits the airbag. Not all touches at collision angles can open the airbag, that is, only when the airbag is hit at a specific angle Only under the premise of detonating the airbag. [0003] In the prior art, it is usually judged whether a collision occurs according to the acceleration of the vehicle body, and then the opening and closing of the safety airbag is controlled. However, only using th...
