With the advancement of vehicle electrification and intelligentization, drive-by-wire (DBW) chassis technology has become a core foundation for achieving high-level autonomous driving, attracting widespread industry attention. Since its establishment in 2016, Shanghai Tongyu Automotive Technology Co., Ltd. has focused on the R&D and industrialization of key DBW chassis components and has become a leading enterprise in this field in China.
1. Braking Systems: From Vacuum Boosters to EMB
Traditional braking systems are gradually evolving toward Electronic Hydraulic Braking (EHB) and Electronic Mechanical Braking (EMB). EHB offers fast response and high energy recovery efficiency, while EMB further enables fully dry, hydraulic-free braking, better meeting the redundancy requirements of advanced autonomous driving.
2. Steering Systems: From EPS to SBW
Steer-by-Wire (SBW) systems eliminate mechanical connections and achieve steering control through electronic signals. They support features such as steering wheel folding and variable transmission ratios, providing more possibilities for intelligent cabins and autonomous driving.
3. Suspension Systems: From Passive to Active
Active suspension systems adjust stiffness and ride height in real time according to road conditions, balancing comfort and handling, while reducing drag and improving energy efficiency.
4. Chassis Control: From Distributed to Centralized
Chassis Domain Controllers (CDCU) enable coordinated control of braking, steering, and suspension systems, supporting software-hardware decoupling and platform-based development, laying the foundation for intelligent vehicle upgrades.
1. Drive-by-Wire Braking Systems
EHB (Electronic Hydraulic Braking): Features mechanical decoupling, fast response, low noise, with over 500,000 units in mass production.
iEHB (Integrated Electronic Hydraulic Braking): Integrates EHB, ESC, EPB functions, supporting ASIL-D functional safety.
EMB (Electronic Mechanical Braking): Fully dry solution with response time <100ms, completed winter-standard validation.
2. Steer-by-Wire (SBW) Systems
Supports silent steering, variable transmission ratio, and redundancy design. Successfully passed winter calibration tests and received high customer recognition.
3. Drive-by-Wire Suspension System (iASU)
Integrated air supply unit with compact size, low noise, and high energy efficiency. Supports active height and stiffness adjustment.
4. Chassis Domain Controller (CDCU)
Supports integrated control of braking, steering, suspension, and drive systems. Features dual MCU redundancy, Gigabit Ethernet, CAN FD interfaces, and meets L3+ autonomous driving requirements.
Leveraging the technical background of Tongji University, Tongyu Automotive undertakes multiple national-level R&D projects and possesses full-process capabilities from concept design and system development to mass production validation. The company has obtained IATF 16949, CMMI Level 3, and ASIL-D functional safety certifications. Its testing facilities cover HIL, NVH, high/low temperature, and durability testing scenarios.
Tongyu products are widely applied in passenger cars, commercial vehicles, autonomous buses, logistics vehicles, airport tugs, and more. Clients include over 80 companies such as Dongfeng, FAW, BYD, JAC, Leapmotor, and Neta, and the company has participated in major projects including the Beijing Winter Olympics and National Games for autonomous vehicle support.
Driven by the philosophy of "learning for practical use, technological entrepreneurship, and serving the country through industry," Tongyu Automotive continuously promotes independent control of China’s core DBW chassis technologies. Moving forward, the company will further deepen its product portfolio and support China’s automotive industry in entering a new era of intelligent vehicles.
In 2026, the China International New Energy Vehicle Technology, Components, and Services Expo will gather global technology and product showcases. The event provides an international cooperation platform for supply chain enterprises, reflecting efforts to build a mature and comprehensive supply chain ecosystem in China.
