Embodiment Construction
[0043] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident, however, that these embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing one or more embodiments.
[0044] Affected by factors such as wheel jump, the suspension is in a state of non-stop motion during the running of the vehicle V. Taking the upper suspension arm 505 of the double-wishbone suspension as an example, it is clamped with the vehicle body 504 at the wheel top. Angle A is just in constantly changing, and the scope of A increases along with the increase of jump stroke, has a strong impact on the ejection direction of the protective air bag 421 in the air bag assembly 42 of suspension spring failure emergency protection device 4 in the present inve...

The invention discloses a suspension spring failure emergency protection control system and method based on thrust vectors, and belongs to the field of vehicle safety. An input interface of a centralprocessing module is connected with a suspension state monitoring module, and an output interface is connected with a control module and an alarm. The core mechanism of an execution module is a suspension spring failure emergency protection device which comprises an air bag assembly, a thrust vector assembly, an anti-collision block and the like; the air bag assembly comprises an air generator, aprotection air bag and the like, and the thrust vector assembly comprises an air storage tank, a proportional valve, a vector nozzle and the like. When abnormities such as sudden failure of suspensionsprings occur, the system can give an alarm or execute emergency protection operation simultaneously according to information such as spring stress, vehicle loading conditions and the angle of a swing arm on a suspension relative to the vehicle body part at the wheel top: detonating the protection air bag at the failure suspension spring in a proper mode to enable the protection air bag to be inflated and popped up, and under the action of the thrust vector assembly, the protection air bag is vertically embedded into a pit of the anti-collision block and plays a role similar to an air spring,impact is relieved, and the posture balance of the vehicle body is kept.
Description
technical field [0001] The invention relates to the technical field of vehicle safety, and more specifically, to a thrust vector-based suspension spring failure emergency protection control system and method. Background technique [0002] Suspension is the general term for all force transmission connection devices between the frame (or load-bearing body) and the axle (or wheel). And the role of guidance, among them, elastic elements often use various springs. As a key component of the suspension, the spring has an important impact on the dynamic performance and running quality of the vehicle, especially the ride comfort, high-speed driving safety, handling during driving and the adaptability of the vehicle to complex road surfaces. , a good suspension spring is one of the key factors to ensure the running performance of the car. [0003] There are many types of suspension springs, but the working environment is complex and the load is constantly changing. In addition, most...
