Embodiment Construction
[0043] In the following description, for the purposes of illustration, many specific details are set forth in order to provide a comprehensive understanding of one or more embodiments. However, it is clear that these embodiments may be implemented without these specific details. In other examples, in order to facilitate one or more embodiments, the well-known configurations and devices are shown in the form of a block diagram.
[0044] Affected by factors such as wheel beating, the suspension is in a state where the vehicle V is inactive, and the swing arm 505 is placed on the suspension of the double-horizontal arm suspension, which is a clip of the wheel 504 with the wheel. The angle A is in non-changing, and the range of A increases from the increase of the jump stroke, which seriously affects the pop-up direction of the protective airbag 421 in the airbag assembly 42 of the suspension spring distortion of the present invention.
[0045] The thrust vector technology refers to t...

The thrust vector-based suspension spring failure emergency protection control system and method belong to the field of vehicle safety. The input interface of the central processing module is connected with the suspension state monitoring module, and the output interface is connected with the control module and the alarm. The core mechanism of the executive module: suspension spring failure emergency protection device, including airbag components, thrust vector components and anti-collision blocks, etc., the airbag components include gas generators and protective airbags, etc., and thrust vector components Nozzles etc. In case of abnormalities such as sudden failure of the suspension spring, the invention can alarm or perform emergency protection operations at the same time according to information such as the force of the spring, the loading of the vehicle, the angle of the upper swing arm of the suspension relative to the vehicle body at the wheel top: detonate in an appropriate way The airbag is protected at the invalid suspension spring, which is inflated and ejected, and under the action of the thrust vectoring component, it is vertically embedded in the bumper pit, which acts like an air spring to ease the impact and maintain the balance of the body posture.
Description
Technical field [0001] Technical Field The present invention relates to vehicle safety and, more particularly, the emergency protection system and method relates to a control failure of the thrust vector based on the suspension spring. Background technique [0002] The suspension is a generic term of all the force transmission means connected between the frame (or monocoque) and the axle (or wheel), an elastic member generally consists of three parts, the damper and the guide mechanism and other components, respectively, from the buffer, the damping and the role of the guide, wherein the elastic member is often employ various spring. As a key part of the suspension, the spring has an important effect on the dynamic performance and operational quality vehicles, particularly affect vehicle ride comfort, high-speed driving safety, the process of moving vehicle handling and adaptability to complex road, so good suspension spring is one of the key factors that guarantee operational pe...
