- Bosch has started real-world Level 3 automated driving tests in Wuxi, marking progress beyond Level 2 systems.
- The collaboration with Chery focuses on advanced ADAS and a new 48-volt electrical architecture.
Robert Bosch GmbH has taken a significant step forward in autonomous mobility by initiating real-world testing of Level 3 automated driving vehicles in China. Since March 2026, the company has been authorized to conduct these trials in Wuxi, reflecting growing regulatory support for advanced driving technologies. This development signals Bosch’s transition from Level 2 driver assistance toward more advanced conditional automation, where vehicles can independently manage driving tasks under specific conditions while reducing driver workload.
Advancing from Level 2 to Level 3 Automation
The ongoing testing program builds upon an enhanced ADAS platform that was previously deployed in the Chery Exeed ES. This system already demonstrates capabilities such as automated braking, steering, and acceleration, but still requires the driver to remain attentive to surrounding traffic. Bosch is now refining this technology to meet Level 3 requirements, where the system can assume full control in defined scenarios like highways and urban expressways, allowing drivers to disengage temporarily from active driving responsibilities.
Performance Capabilities and Real-World Conditions
The system under testing is engineered to operate at speeds of up to 120 km per hour, making it suitable for highway environments. It also functions reliably in weather conditions where visibility extends to approximately 300 meters, ensuring consistent performance in varied driving scenarios. One of its key features includes automated lane-changing, which enhances traffic flow efficiency and reduces driver intervention. These capabilities are critical for achieving scalable Level 3 deployment in dense and dynamic urban mobility ecosystems.

Strategic Collaboration with Chery
In parallel with its testing efforts, Bosch is strengthening its partnership with Chery to accelerate innovation in vehicle electronics. Both companies are expected to announce a joint development initiative focused on a 48-volt electrical system. This collaboration aims to support next-generation vehicle architectures by improving energy efficiency, enabling advanced features, and supporting the increasing electrification of automotive platforms. The partnership reflects a broader industry trend toward integrated hardware and software ecosystems for intelligent mobility.
China as a Key Market for Automated Driving
The selection of Wuxi as a testing location highlights the importance of China in the global autonomous driving landscape. The country’s supportive regulatory environment, combined with its rapidly evolving urban infrastructure, makes it an ideal testing ground for advanced mobility solutions. Bosch’s activities in this region demonstrate its commitment to scaling automated driving technologies in markets that are actively shaping the future of transportation through innovation and policy support.
