As an important actuator of the whole vehicle, especially the key technology to achieve high-level self-driving, wire-controlled chassis is entering a new stage of domestic breakthrough with the rapid development of intelligent electric vehicles.
Recently, according to the list of Chinese passenger car braking system (ESC/One-Box) TOP10 suppliers released by Zoz Auto Research from January to June 2024, in addition to the traditional foreign Tier1 giants, local suppliers such as Fudi Power and Qiangu Technology have occupied a good market share, with a combined market share of 14.
2% in the first half of the year.
Among them, Qiangu Technology, as a rare third-party on-line chassis supplier independent of the whole vehicle factory, ranks firmly in the top three of domestic independent brands by virtue of high-quality products, high stable supply capacity and efficient response service.
You know, no matter the on-line brake or the entire chassis market, it has been dominated by foreign giants for a long time, with few local players.
Today, the rising market share of independent suppliers fully shows that local enterprises have officially entered the core arena of on-line chassis after continuous technological research in the past few years and deep coordination with domestic car companies.
According to Galaxy Automotive, Qiangu Technology is expected to usher in the One-box project of more than two star models by the end of the year.
According to industry estimates, the average monthly sales of these two models are expected to exceed 10,000, which undoubtedly means greater shipments and greater market share for Qiangu Technology.
For this reason, Qiangu Technology will officially open the second phase of Changshu Line-controlled chassis Intelligent Manufacturing Factory in the third quarter, when it will increase its production capacity by 3 million, including brand-new intelligent braking, on-line brake controller and assembly system production line, so as to build a solid support for continuing to lead the market.

The core team of the company has more than ten years of experience in R & D and industrialization of on-line braking, covering many core areas such as software and hardware, machinery, systems and testing.
Among them, the founder of Qiangu Technology is the proposer of the first patent scheme for on-line braking in China.
Based on years of deep ploughing in the field of online control chassis, Qiangu Technology launched the independent research and development of on-line braking system a long time ago.
But unlike many other enterprises, Qiangu Technology chooses ESC as the core entry point of the on-line chassis.
As the basis of the realization of the on-line chassis, ESC can not only “perceive” the state of the vehicle in real time, but also control the safety of the vehicle.
For intelligent vehicles, it is the existence of “cerebellum + limbs”.
Even in the view of Qiangu Technology, ESC’s self-research ability and industrialization landing experience are the core basis for determining the large-scale landing of One-Box and EMB.
Therefore, since its inception, Qiangu Technology has actively consolidated its R & D and industrialization capabilities in the field of ESC.
In 2023, Qiangu Technology ESC officially began to supply in batches.
by the fourth quarter, sales quickly climbed to 200000 sets, with a total sales of 300000 sets for the whole year.
Last year, the market share of domestic passenger car body stability control systems reached 30%.
At present, the monthly supply of ESC of Qiangu Technology is stable at more than 60, 000 sets.
Qiangu Technology has built two ABS&ESC fully automatic production lines and one ABS&ESC semi-automatic production line in the first phase of Changshu Line Control chassis Intelligent Manufacturing Plant, with a total annual production capacity of 1.
6 million sets.
You should know that in the field of ESC, China has been in a monopoly pattern of foreign suppliers for a long time, and Qiangu Technology is also a rare local supplier that has achieved large quantities of ESC shipments.
With the successful mass production of ESC, the One-box EHBI of Qiangu Technology has undergone many iterative upgrades and took the lead in mass production in the industry.
In the past period of time, the continuous increase in the market share of Qiangu online control is a direct proof.
One-box EHBI of Qiangu Technology deeply integrates ABS, ESC, E-booster and EPB, and supports multi-sensor fusion.
Moreover, this on-line braking system is also the first One-box product independently developed in China to integrate VMC vehicle kinematics control software, which is based on ESC algorithm, supports multi-input and multi-output, and can achieve high-level body stability control and full-efficiency energy recovery with a variety of dynamic characteristics.
VMC of Qiangu Technology adopts multi-input and multi-output algorithm, combined with accurate vehicle model, which well solves the problems such as lack of multi-sensor fusion and inconsistent coordinated control of multi-actuators, and can improve the measurement accuracy of vehicle parameters by 70%.
Reduce the convergence speed of the drive shaft by 50%, and greatly improve the accuracy and response speed of the system.
At present, Qiangu Technology’s One-box on-line brake has been recognized by many mainstream car companies and platform fixed-point projects, and its VMC core algorithm has experienced more than 5 million of the intelligent brake industrialization verification.
In order to support the large-scale production of EHBI, Qiangu Technology has built a fully automatic production line with an annual output of 400000 pieces of ECU controllers and a general assembly line with an annual production capacity of 400000 sets of EHBI, in order to quickly meet the large-scale carrying needs of the terminal market.
On this basis, Qiangu Technology is actively pre-researching the next generation on-line brake product EMB, and successfully launched a “wet and dry front” multi-actuator joint control scheme, that is, the front wheel uses EHB to provide greater braking force, and the rear wheel adopts EMB.
Through the wheel speed tracking algorithm based on slip rate control, the rear axle EMB realizes the ABS and VDC functions based on chassis domain control algorithm.
According to Gaishi Automotive, Qiangu Technology’s “wet front and dry back” combination scheme has been mass-produced, and the relevant automobile enterprise cooperation projects are being steadily advanced.
It is expected that in 2026, Qiangu Technology will officially achieve small batch production of EMB.
Qiangu Technology ESC, EHBI and EMB products, picture source: Qiangu Technology, independent progress, Qiangu logic and strength, there is no doubt that in the process of localization of online control chassis, Qiangu Technology has become the backbone of independent breakthrough by virtue of continuous technological innovation and increasing market share.
However, this is no accident.
Looking back at the evolution of Qiangu Technology’s on-line brake products in the past few years, no matter from ESC to EHB, or from EHB to the more electronic EMB, Qiangu Technology has fully applied the application layer model design concept of decoupling and modularization to efficiently meet the rapid landing and customized development needs of the whole vehicle factory for rich functions.
Specifically, when developing the next generation EMB, Qiangu Technology takes advantage of the mature mass production of ESC and EHB to apply several modules in the EHB system to EMB product development to improve the efficiency of EMB research and development.
It is reported that Qiangu Technology’s EHB and EMB have about 70% of the technology in common.
Because of this, Qiangu Technology can take the lead in completing it in the industry.
The “front wet and then dry” combination plan is mass-produced and put on the car.
, In the next stage, in Qiangu Technology’s view, domestic suppliers will play a leading role, including the localization of core chips.
To this end, Qiangu Technology is making every effort to promote the localization of all chips, and has a corresponding domestic plan.
It is expected to officially produce mass production in 2025.
, In this process, in order to better respond to the rapid iterative needs of OEMs in the end market, Qiangu Technology has implemented a full development process from requirements traceability to architecture, design, testing and code in Autosar based on a white-box open ecosystem.
, and built a unified version management system to quickly match the diversified development needs of OEMs.
, Qiangu Technology has also established a unified and open continuous integrated management platform to further speed up the development process.
Qiangu Technology can provide technical support for OEM code warehouses.
On the premise of highly complying with OEM rights management, it can achieve continuous integration of functional development, real-time release, and quickly generate test reports for efficient functional iteration and output.
Thanks to continuous technological innovation and a complete service system, Qiangu Technology has built a solid market foundation in the field of brake-by-wire in just two years.
According to statistics, up to now, Qiangu Technology has obtained more than 50 vehicle models from 8 major customers, covering multiple passenger car models and commercial models from local leading car companies and new forces.
Recently, in order to better promote the upward breakthrough of domestic wire-controlled chassis, the “Intelligent wire-controlled chassis Joint Laboratory” jointly built by Wuhan University of Technology, SAIC-GM-Wuling, Baolong Technology, and Qiangu Technology was officially established.
According to Gashi Automobile, the joint laboratory aims to form a joint research team for smart chassis by gathering the efforts of universities, automobile companies and parts suppliers, promote the rapid marketization of scientific research results, and accelerate the realization of domestic wire-controlled chassis not only “from 0 to 1”, but also “from 1 to 100” leap and breakthrough.

Not only that, Qiangu Technology has also gained widespread recognition in the capital market.
Since 2022, Qiangu Technology has completed 6 rounds of financing.
There are many investors from well-known industries and professional investment institutions such as Xiaomi Zhantou, Zhengxuan Capital, Haila Electronics, Xiamen Construction Development, and Lanhu Capital.
Behind this series of outstanding achievements, Qiangu’s strong resilience and explosive power as a third-party wire-controlled chassis supplier.
Although many OEMs currently cultivate “direct” suppliers internally at line-by-wire chassis tracks, it is undeniable that such models are often limited to within the group.
In the long run, if the wire-controlled chassis field wants to truly create Tier1 giants such as Bosch and China, it can only be more open and independent.
And this is also the goal that Qiangu Technology will continue to pursue in the future.
