The 2025 Shanghai Auto Show concluded successfully, and among the highlights of this global automotive technology summit, intelligent chassis technology emerged as a central focus. From IM Motors’ “Steer-by-Wire Digital Chassis” to Leekr Technology’s “Intelligent Chassis 2.0” and Schaeffler’s steer-by-wire system, the industry is breaking away from traditional mechanical constraints at an unprecedented pace, opening new possibilities for autonomous driving and user experience.

Intelligent Chassis Technology: From Concept to Mass Production

At the 2025 Shanghai Auto Show, IM Motors released its steer-by-wire digital chassis, which broke free from traditional mechanical limitations through a full-wire control architecture. It achieves three-direction, six-degree-of-freedom integrated control in the X/Y/Z axes, allowing a nearly 5-meter-long vehicle to achieve a turning radius of just 4.69 meters. During low-speed parking, the steering wheel only needs to turn 150 degrees, reducing steering effort by 40% compared to traditional systems. Its dual-redundant dry-type brake-by-wire system responds 2–3 times faster than traditional hydraulic systems, shortening braking distance by 6%–8%.

The “Lingxi Blowout Stability System” can control lateral deviation to less than 1.5 meters even during simultaneous tire blowouts on all four wheels, greatly enhancing safety redundancy. This system also supports decoupling of human and machine control for L3/L4-level autonomous driving.

Leekr Technology introduced its fully domestically developed brake-by-wire solution (IHB-LK® GEN4.0), marking a significant milestone in China’s self-sufficiency in core components.

Bosch Group also launched a locally developed steer-by-wire solution, which has already received orders from three Chinese OEMs and is scheduled for mass production in Q4 of 2025, further advancing the global rollout of wire-control technologies.

These technological breakthroughs validate the intelligent chassis’ advantages in handling and safety while accelerating the deployment of L3/L4 autonomous driving.

Industry Trends in Intelligent Chassis: Wire-Control, Integration, and AI Collaboration

Technologies showcased at the 2025 Shanghai Auto Show reveal three major trends in intelligent chassis development:

Full Wire-Control Replacing Mechanical Structures: Technologies such as Steer-by-Wire (SBW) and Electromechanical Braking (EMB) are gradually replacing traditional hydraulic and mechanical systems, enabling millisecond-level response and precision control.

Cross-Domain Collaborative Control: Deep integration of intelligent chassis and autonomous driving is becoming a trend. Domain controllers integrate steering, braking, and suspension systems. Combined with AI algorithms to anticipate road conditions, they enable dynamic, adaptive vehicle control.

Redundant Safety Design: Dual power sources and dual ECU architectures are becoming standard in high-level autonomous systems, ensuring reliability under extreme conditions.

Smart Manufacturing: The Key Driver Behind Intelligent Chassis Deployment

The complexity and precision of intelligent chassis technologies present significant challenges for production. For instance, steer-by-wire systems require micrometer-level precision in sensor assembly, millisecond-level response testing of control units, and full lifecycle data traceability. This is where high-end automated production lines add value—through precision assembly, AI visual inspection, and flexible production line design to ensure the reliability and consistency of wire-controlled components.
