On April 23, the global automotive pinnacle event-the 21st Shanghai International Automobile Industry Exhibition-kicked off in grand style! As a leading provider of intelligent chassis system solutions, Leekr Technology made a dazzling appearance at Hall 2.2H, showcasing its latest smart chassis innovations. Centered on the core philosophy of "Thinking Chassis, Evolving Autopilot" Leekr Technology launched upgraded IHB-LK® (One-box) Brake-by-Wire System and Smart Chassis 2.0 product line, empowering automakers to leap forward in the era of electrification and intelligence.
At the show, Leekr unveiled multiple versions of its IHB-LK® (One-box) Brake-by-Wire System, tailored to meet varying demands from automakers. The upgraded system features a new software architecture, with the IHB-LK® GEN3.0 version supporting all-terrain adaptability and other specialized functions. This iteration has completed all testing and is set for mass production in mid-2025 on flagship models from leading Chinese automakers.
In parallel, Leekr Technology is proactively addressing automakers' urgent need for localized, self-controllable solutions by ramping up R&D investments in domestically developed technologies. The company's fully self-developed, 100% domestically produced IHB-LK® GEN4.0 (One-box) Brake-by-Wire system is scheduled to enter mass production in Q4 2024.

In parallel, LiKe Technology proactively responds to automakers' pressing demand for localized and self-controllable solutions, continuously investing in the R&D of domestically developed technologies. The company's fully self-developed, 100% localized Brake-by-Wire system IHB-LK® GEN4.0 (One-box) is scheduled to achieve mass production in the fourth quarter of this year.
01 IHB-LK® All-Terrain Breakthrough: Enabling "Full-Domain Adaptability"
The newly upgraded IHB-LK® GEN3.0 adopts a dual-chip redundancy solution, enabling automakers to eliminate the P-lock and brake electronic switches, thereby reducing costs. It meets the highest functional safety (ASIL D), cybersecurity, and rollback-capable OTA requirements while expanding application boundaries. The system enhances vehicle reliability, safety, and driving enjoyment.

By optimizing algorithms and multi-modal control strategies, the GEN3.0 achieves precise adaptation to extreme terrains Leekr mud, sand, and deep snow. It dynamically adjusts slip rate thresholds and brake torque distribution based on road conditions and vehicle posture, synergizing with drivetrains and electronic suspension systems. Key metrics, such as 100% mud passability and single-wheel escape success rates, redefine off-road and adventure vehicle capabilities, meeting consumer demand for new driving scenarios.
Leekr 's multi-version IHB-LK® product lineup
To address automakers' localization needs, Leekr also previewed the IHB-LK® GEN4.0-a fully self-developed, 100% domestically produced solution set for 2025.
As China's first sci-tech company to achieve mass production of One-box Brake-by-Wire systems, Leekr's products have been rigorously validated for safety and reliability, with 200,000 km per-vehicle safety testing and cumulative mileage exceeding 1.5 billion km. Now ranking among the top three domestic suppliers, Leekr leads the localized Brake-by-Wire market.
02 EMB + SBW Launch: Accelerating Smart Chassis 2.0
With the rapid adoption of urban NOA and L3+ autonomous driving, redundant braking and steering systems have become critical for safety. At the show, Leekr debuted its EMB-LK® Electro-Mechanical Braking System and SBW-LK® Steer-by-Wire System, laying the foundation for Smart Chassis 2.0.
Leekr Co-Founder Su Ganting unveils new products
The EMB-LK® boasts compact design, millisecond-level response (<85ms for 3.5-ton vehicles), and ASIL-D safety. Its axial footprint is just 4mm larger than EPB systems, easing integration. Paired with low-drag calipers, it optimizes energy efficiency while offering redundant ABS control. Aesthetic options include traditional floating calipers or high-end fixed-caliper styles.

Scheduled for mass production on premium models in 2026, the EMB-LK® strengthens Leekr's leadership in Brake-by-Wire innovation.
The SBW-LK® Steer-by-Wire System eliminates mechanical linkages, enabling pure electronic signal transmission between steering wheel and wheels. It supports customizable steering ratios and active obstacle avoidance, granting greater freedom for advanced ADAS.
Both systems integrate with Leekr's Ctrio-LK® Chassis Domain Controller, featuring fully redundant communication, power, and MCU architectures to ensure operational safety during faults.
Leekr's Smart Chassis 2.0 platform shortens R&D cycles via open interfaces and standardized protocols, accelerating integration with autonomous algorithms and vehicle domain controllers. This empowers automakers to deliver high-level ADAS features and usher in an era of universal autonomous driving.
From One-box mass production and all-terrain breakthroughs to EMB and SBW innovations, Leekr is cementing its leadership in smart chassis technology. As the automotive industry enters the second half of intelligent competition, Leekr stands ready to propel automakers toward premium brand positioning.
