The market in China is striving for higher levels of automation than Level 2, and vehicle manufacturers are increasingly asking for Level 3 driving functions. At the same time, the corresponding legislation for private vehicles is soon to be finalized. In this environment, Bosch is working on Level 3 automated driving.

China remains the growth engine of the global automotive market, as this year's Beijing Auto Show once again makes clear. It is clear that the Middle Kingdom is striving for higher levels of automation. Not only is there increasing demand for level 3 driving functions, but the government is also working on finalizing the corresponding legislation for private vehicles. In this environment, Bosch Mobility is taking the next step in its development—from level 2 to level 3. Since March 2026, the company has been licensed to test vehicles with level 3 driving functions in real operation in Wuxi, China. Bosch is relying on an advanced ADAS system solution that is used in the Chery Exeed ES. With this assistance system, the vehicle brakes, steers and accelerates independently, while the driver has to keep a close eye on the traffic. This changes from Level 3, where responsibility is transferred to the vehicle in certain applications. The driver can take their hands off the steering wheel and their eyes off the road. The system drives at speeds of up to 75 mph, works in weather conditions with visibility of up to 1,000 feet and changes lanes automatically.

Software And Hardware Solutions

Expertise in all core vehicle areas such as drive, steering, brakes, vehicle sensors, high-performance computers, on-board electronics, software and artificial intelligence play an important role in the development of assisted and automated driving. This is where Bosch wants to contribute its expertise and provides both the hardware, such as radar, and the algorithms. In addition, the supplier operates globally and can therefore offer economies of scale and a high level of safety, as Markus Heyn, member of the Bosch Board of Management and Chairman of Bosch Mobility, explains. "We can transfer knowledge from one market to another. Our goal is to be the preferred partner for Chinese and Western manufacturers." A level 3 system for private vehicles, which relieves the driver of the task of driving for longer periods of time, is also attractive for large countries such as the USA with its wide highways, but also for Europe. Stefan Hartung, Chairman of the Bosch Board of Management, adds: "Anyone who, like us, is able to adapt their range and supply chains to regional conditions and at the same time deliver at a global level has a clear advantage."

By-Wire Technologies for SDVs

By-wire systems for braking and steering are a key technology for software-defined vehicles - an important area of business for Bosch. Signal lines transmit the driver's wishes to the braking and steering system. For brake-by-wire, the supplier offers a solution consisting of two independent braking devices: a newly developed brake actuator and a traditional ESP system. Bosch has already concluded supply contracts for the hydraulic brake-by-wire system with five manufacturers and is expected to launch it in series production in passenger cars for individual transportation in mid-2026. It will also be used in several robotaxi platforms. In addition to the hydraulic solution, Bosch is also offering a purely electromechanical system. Bosch says it has the right braking system in its portfolio for every vehicle manufacturer.

Progress With the Electric Drive

Bosch has produced more than 25 million components for electrified driving. By 2026, the company will supply more than seven million components and systems for electric and hybrid vehicles worldwide. Bosch supplies over 30 car manufacturers in the lead market of China.

The company also supplies the right electric drive for everything from small cars to sports cars. The engineers were able to reduce the efficiency losses of the electric motor by up to 30 percent. To achieve this, they made great strides in the optimization of electrical sheets, the winding and, in particular, the cooling. Stator windings made of aluminum instead of copper are suitable for small and compact electric cars. This reduces costs and weight. For sporty vehicles, Bosch is able to increase the power density of the electric motor by 50 percent (up to 10 hp per kg). (se)
