, At present, the demand for air spring configuration of the whole vehicle is getting stronger and stronger, and the new car platform is basically standard.
traditional car companies such as SAIC, Changan, BYD, Geely and Chery have also begun to develop and produce air spring models to increase the comfort and selling points of the whole vehicle.
Although the air suspension system with air spring has a broad market prospect, there are still some technical barriers in the supply of this product.
From a global point of view, the established air suspension suppliers represented by mainland China and Weibak have a more comprehensive supply capacity covering ECU, air springs, shock absorbers and other components, while Weiboke has accumulated deep experience in the field of commercial vehicle air suspension.
Few domestic enterprises have fully mastered the air suspension technology.
Baolong Technology started the air suspension business in 2012 and mastered the core technology of air suspension, including system function development, design verification, automatic assembly technology, adjustment technology, air spring rubber technology and so on. , 2. It has a full set of components of “perception + decision + execution”.
Thanks to years of accumulation, Baolong Technology now has a full set of components for perception, decision-making and execution required by the air suspension system.
That is, the perception part of the binocular stereo vision system, height sensor, acceleration sensor, as well as the control and execution part of the intelligent electronic shock absorber (CDC), air spring, gas storage tank, gas supply unit and suspension controller have also been fixed-point and mass production.
Among them, the air spring assembly has obtained more than 20 project fixed points of 8 automobile companies, and the gas storage tank has obtained more than 70 project fixed points, making it a leading head enterprise.
Baolong Technology in the air suspension business, in addition to the pipeline, comprehensive mass production, from rubber formula to software algorithm comprehensive self-development, with a wide variety of mass-produced products, high self-control rate of parts, flexible business model and international operation architecture to gain competitive advantage. 3. With the combination of ADAS and air suspension, the road preview system of active suspension is developed to realize the longitudinal control of the vehicle by ADAS.
The active suspension road preview system based on binocular stereo vision developed by Baolong Technology can significantly improve the ride comfort and safety after the vehicle is installed with the system.
At present, the project has been designated by a number of car companies, and has been mass production.
The road surface information is scanned in real time by binocular stereo vision, and the road surface roughness and concave and convex foreign bodies in front of the vehicle are detected in advance, and the 3D point cloud image of the road surface is obtained.
through the internal self-developed DeepFusion road surface concavity height measurement algorithm, the real-time information of the target and road height is calculated and sent to the suspension controller and chassis system in real time to help the chassis accurately adjust the damping and height state of the suspension according to the front road surface in advance.
So as to counteract the vibration impact of the uneven road surface on the chassis and maintain the same comfort and safety as the peaceful and shun road.
Application scenario: the intelligent air suspension system includes air spring shock absorber assembly, gas storage tank, height sensor, body acceleration sensor, suspension control unit (ECU), air supply system, etc.
, in which the air suspension controller (ECU) is the core component, which bears the “brain” function of the whole system, and can meet the needs of drivers, vehicle status and road shape.
The self-adaptive adjustment of the body height is realized by controlling the filling and deflation of the air spring, and combined with the electronically controlled shock absorber to comprehensively adjust the suspension height, stiffness and damping, improve the vehicle comfort, energy economy, passability, convenience and stability, and improve the driving quality in an all-round way.
Future prospects: because the air suspension system can significantly improve the driving experience, the early stage is mainly configured in imported luxury cars, and the key components are also mainly produced by foreign giants.
At present, the major mainframe factories, especially the emerging intelligent electric vehicle enterprises, in order to seize the market, the new generation of models are almost all equipped with standard air suspension system, forming a market tuyere and broad prospects.
In the past two years, with the increasingly fierce competition in the automotive field, the air suspension system, the original high-end vehicle configuration, has become a standard or optional device for mid-end cars.
The price of models carrying empty suspension has a continuous downward trend.
At present, models worth about 300000 yuan have become standard, and a small number of models have reached about 200000 yuan.
There is still much room for growth in this market in the future.
