The first new energy vehicle in China： BYD Han is equipped with Bosch IPB intelligent integrated braking system.

Byd Han is the first new energy production vehicle equipped with Bosch’s "IPB Intelligent Integrated Braking System" in China, and the "CST Comfort Braking Function" based on the IPB system has achieved the world premiere in Han. IPB system helps Han achieve leading safety, comfort and long battery life.

Safety first, smarter braking system

The full name of IPB is "Intelligent Integrated Brake System". The so-called "intelligence" means that IPB is an electronically controlled braking system. Compared with the traditional vacuum booster pump braking system, it makes the braking system respond more quickly and control more accurately, and with this intelligent electronically controlled braking system, it can be extended to more functions. When IPB is combined with new energy vehicles, the efficiency of braking energy recovery can be significantly enhanced. The so-called "integration" means that the IPB integrates the ESP system. Compared with the non-integrated brake system, the IPB system is lighter in weight and takes up less interior space.

Previously, in the process of Han’s vehicle development, BYD and Bosch made the IPB system highly match Han’s vehicle performance by repeatedly testing and adjusting more than ten BYD Han vehicles for several months, and improved Han’s performance in braking, acceleration, avoidance, comfort and endurance.

Such a high standard of rigorous testing and adjustment stems from BYD’s pursuit of high quality. As a high-end car, Han should not only pursue the most cutting-edge equipment and advanced performance, but also let users enjoy the leading technology with peace of mind.

Fast, sensitive and safer braking system

"There are thousands of roads, safety comes first", and driving safety is a topic that everyone is very concerned about, especially for Han, who is positioning high-grade.

Automobile braking system plays the most critical role in driving safety, especially after the automobile braking system integrates anti-lock function, traction control function, body stability system, electronic slip limit function, automatic braking and other functions, the role played by the braking system is no longer as simple as "stopping the car".

The traditional braking system relies on the brake pedal to drive the vacuum booster pump to generate braking pressure, and the IPB system adopted by Han converts the displacement of the brake pedal into a signal. The controller combines other sensor parameters to calculate the required braking force, and then the motor drives the brake fluid to establish the braking force. Obviously, IPB can generate braking force more quickly and accurately, which greatly improves the safety of Han. Especially when the "AEB automatic emergency braking" function is triggered, the response time of the traditional braking system is about 600 milliseconds, while IPB can provide the maximum braking force within 150 milliseconds, which is faster than the blink of an eye.

Endurance and comfort coexist, and feel the future car life.

Frequent "nodding" when braking is an important factor affecting comfort. In particular, drivers have different experiences and styles. When most drivers brake, the car body "nods" obviously, which makes passengers very uncomfortable.

After the combination of IPB system and Han, this problem was solved by "intelligence". In Han, Bosch launched the "CST comfortable braking" function based on IPB system in the world. It can provide a smoother and more comfortable experience for drivers and passengers on the premise of ensuring braking safety.

In the process of braking, whether the driver is an "old driver" or not, CST function can make the braking system automatically and intelligently adjust the braking power to avoid the phenomenon of "nodding" when braking, and provide a smoother and more comfortable experience for drivers and passengers. Of course, CST function always puts Han’s safety performance in the first place. For example, when the vehicle tends to lose stability in an emergency, or when the AEB automatic emergency braking function is triggered, or when the driver is in emergency braking, the CST comfort braking function will automatically quit.

In addition, due to BYD Han’s status as a new energy vehicle, the combination of Han and IPB not only improves safety, but also brings "long battery life" effect.

When braking, IPB cooperates with Han’s drive system. First, the motor is used for energy recovery, and kinetic energy is converted into electric energy and stored in the power battery. Once the braking effect of the motor cannot meet the requirements of the braking system, IPB will quickly release the brake fluid and start the brake caliper to brake. This process allows Han to recover 10% more energy when braking. For users, the cruising range is improved and the wear of brake pads is reduced.

It is not difficult to see that Han is equipped with Bosch IPB, and the safety, comfort and endurance of the whole vehicle have been significantly improved. A high-quality car condenses the wisdom and hard work of countless autobots who fight day and night. As the first new energy production car equipped with Bosch IPB, Han’s safety, performance and luxury confirm BYD’s pursuit of high quality.
