Safety is the bottom line of electric vehicles, and Jingweida is giving “China’s answer” to this.
Recently, Tesla, a leader in the electric vehicle industry, has suffered frequent accidents, and its safety issues have attracted the attention of global car consumers and also impacted people’s confidence in the safety of electric vehicles.
On the one hand, many traffic accidents are suspected to be caused by the failure of the braking system; on the other hand, frequent “ghost brakes” reveal that the AEB (system automatic emergency braking) function still has a lot of room for optimization. But in the end, the problem all points to the direction of “braking”.
Brake, also known as the brake system. Whether it is a traditional fuel vehicle or an electric vehicle, the braking function is one of the most core key technologies in the entire vehicle, and its importance to drivers and passengers far exceeds other aspects.
At present, in the market competition of electric vehicle braking systems, foreign companies still have strong brand advantages. However, when mass-produced standard accessories, either independently or in an integrated form, are installed in various models produced around the world, there is a great possibility of “acclimatization”.
Jingweida Automotive Technology, which has been deeply involved in electric vehicle braking for ten years, has a deep understanding of how to do a good job in braking in China’s unique traffic scene.
There are no standard answers to security questions, only the most appropriate ones
As a company that develops automotive intelligent driving and safety collision avoidance systems, Jingweida Automotive Technology’s current new electro-hydraulic braking system and intelligent collision avoidance system have achieved mature applications and mass production.
The executive general manager of the company, Gao Zhan, told reporters that the new energy vehicle that bid farewell to the traditional engine has also changed its braking system.
“Although from a technical point of view, the braking technology of traditional fuel vehicles can still be applied to electric vehicles, it is no longer applicable in terms of performance, systematization and cost-effectiveness.” The system has been transformed from a purely mechanical structure driven by an engine used in traditional fuel vehicles to a more integrated braking system that integrates mechanical, Electronic, hydraulic and software control.”
Magnesium.com found that currently the mainstream electric vehicle braking systems in the international market are: Bosch’s ibooster series, Continental’s MK C1 and IPB and other products.
Jingweida Automotive Technology has also launched its own electro-hydraulic braking system – iCAS-Brake. However, unlike other manufacturers, especially foreign manufacturers, Jingweida pays more attention to the actual needs of customers and the application of actual landing scenarios.
Gao Zhan told Meike.com that maintaining in-depth interaction with car manufacturers on products is a consistent practice of Jingweida since its inception, and it is also an advantage for similar Chinese manufacturers to compare with foreign manufacturers.
“For some traditional technology platforms in Europe and the United States, when designing some core components, they often develop a Model according to their inherent logic. The attitude of cooperation is relatively closed, and this is used as a standard solution to customers.”
Gao Zhan believes that this approach has been proven by the market (especially in the Chinese market) to be not the best choice. More car companies, more demands, and more technical changes. Compared with giving the car factory a standardized product, Jingweida pays more attention to whether the product really helps the car factory, and even the end customers that the car factory faces to solve the problem of demand. .
Through sufficient communication, Jingweida can help car manufacturers find some unanticipated problems and propose reasonable solutions. This forward-looking and down-to-earth style of making products has made Jingweida gradually come to a leading position in technology among its domestic counterparts.
Build an ecological closed loop around braking, and strive to provide “Chinese scene” adaptation solutions
As one of the assisted driving functions, the importance of AEB (System Automatic Emergency Braking) in driving, and even its impact on the future development of smart cars, is gradually being reflected.
Magnesia.com learned that the auxiliary braking system needs multi-level cooperation to help or even replace the driver to make correct braking behavior. The auxiliary braking system can be divided into three layers, namely: perception, decision-making and execution layers. However, at present, car manufacturers often use solutions from different companies at each level, even at the same level, and finally the car factory itself does the overall integration work, which brings certain risks to the driving process.
For example, when the signal is transmitted from the perception layer to the decision-making layer, since the judgment and control logic of the scene may be different in the design, the “dangerous scene” identified by the perception layer is considered to be a “dangerous scene” by the decision-making layer. “Safety”, for the entire braking system, there will be a consequence of confusion and even failure. And the cooperation between different accessories on the same level is also difficult to achieve “seamless connection”;
The “scenario” is also an issue that is often overlooked by car manufacturers. Because to meet the assisted driving or braking requirements in different regional scenarios, a large amount of data learning is required, which is a difficult point for car manufacturers;
In addition, in order to make the integrated rear auxiliary braking system more effective, the car factory may modify some codes of execution and other levels, which also brings hidden dangers to the stability of the braking system.
For the above problems, Jingweida also gave its own solutions:
First, carry out joint development and product deep implantation with car manufacturers;
Secondly, because of the advantage of completely self-developed products, Jingweida can put forward some technical requirements for the car factory in the communication, so as to better exert the performance of the product and avoid risks;
Finally, Jingweida has created a “closed-loop ecosystem” around the braking direction, which can solve the potential matching risk between the middle layer and the layer of the system.
Gao Zhan said that Jingweida “first is to meet the needs of car manufacturers; and adapting to the needs of China’s traffic scenarios is our real core.”
School-enterprise alliance to strengthen academic implementation and speed up talent training
Any outstanding enterprise has a common characteristic, that is, the emphasis on talents, and Jingweida Automotive Technology is no exception. At present, many talents in the team come from domestic car manufacturers, which allows them to better understand the deep-seated needs of customers. In addition, Jingweida also attaches great importance to the cooperation with universities.
“Universities are now a good platform for us to cooperate and cultivate technology. The basic level of our cooperation with universities is the deployment and application of technology. Universities have cutting-edge academic needs and experimental project needs, which can help verify our Some brand-new ideas and technologies. Then we feed back some results of these experimental project technology carrying applications to the development team. In this process, we use this mechanism of cooperation with university projects to carry out an iterative precipitation of technology.” Gao Zhan told Magnesium.com.
Through cooperation with colleges and universities, it has given academia more opportunities to contact the industry, so that academic achievements can be closer to the needs of real use and more “grounded”, which is in line with the academic research direction desired by the country.
Jingweida can learn and innovate from technical research in academia, so as to complete the iterative precipitation of some of its own technologies; and it can also allow more high-level talents in the school to have the opportunity to enter the automotive industry. This will serve as a source of living water for the future development of the company itself and China’s auto industry.
At present, Jingweida still focuses its strategic core on technology. In order to improve the technical strength, especially some key technologies to break the “stuck neck” of autonomous driving, in addition to expanding the talent team, Jingweida is still accepting cooperation from car manufacturers. While solving practical problems, it can also break through some existing technical bottlenecks. In terms of cost, Jingweida has always controlled at a level that allows customers to feel “high cost performance”, which truly promotes the development of China’s auto industry.
It goes without saying that electric/smart vehicles are the future of the automotive industry. Global car factories and even the upstream and downstream industry chains have been involved in this wave of transformation to electrification and intelligence. However, no matter what kind of drastic changes the automotive industry has undergone, “safety” is always its eternal bottom line. How to provide high-safety electric vehicles suitable for Chinese scenarios, and how to continue to maintain the advantages of Chinese car manufacturers in this global competition, Jingweida is giving its own answer.
