ZF Decode a new generation of commercial vehicle brake system platform mBSP XBS

From the introduction of the world's first commercial vehicle ABS system in 1981 to the creation of the commercial vehicle EBS era in 1996, ZF has always sought a breakthrough braking technology solution to improve vehicle and road safety. MBSP XBS modular brake system platform is another revolutionary upgrade of ZF's leading commercial vehicle brake control technology. At present, the system will be fully implemented in mass production in China, enabling the intelligent and motorized development of commercial vehicles in China and assisting in improving road traffic safety.

Highly integrated

MBSP XBS is a braking system platform specially developed by ZF for commercial vehicles. Its outstanding features are highly integrated parts and modular design. Compared with existing ZF EBS, the system layout is further simplified. This is mainly due to its core component, the CMAx central bridge control module. It integrates ECU, electronic stability control module, dual-channel rear axle module and other components in the original system into the only ECU microcontroller of the whole system, and is installed on the chassis. It not only reduces system components by 30%, but also provides better design flexibility for vehicle design, reduces installation space requirements and assembly process, and reduces total cost of ownership (TCO).

Safety Re-Upgrade

MBSP XBS modular brake system platform adopts active wheel speed sensor (aWSS), which can accurately monitor the driving speed and direction of the vehicle, further optimize the wheel slip control capacity, give full play to the vehicle brake performance under complex road conditions such as wet and low adhesion, and improve the driving safety.

MBSP XBS can be extended to autopilot application scenarios based on the same basic platform. In case of failure of the main brake system, mBSP redundant CMAx can replace the main CMAx to realize normal operation of the brake system within the regulatory scope. In addition, the system is fully compatible with ZF's latest OnGuardMAX commercial vehicle advanced driver assistance system, providing automatic emergency braking, full-speed ACC (including automatic following start-stop) and other functions to ensure driving safety and driving comfort.

Compliance with Global Standards

MBSP XBS meets the requirements of relevant global information security regulations, such as General Security Regulations (GSR) of European Union and GB 44495 Technical Requirements for Information Security of Complete Vehicle. At the same time, it is fully designed and developed according to ISO26262 standard, reaching the highest safety level ASIL D. Relying on the global platform architecture, mBSP XBS adopts the unified hardware platform and interface design, which can flexibly adapt to the regulatory requirements and application scenarios of different countries and regions, simplify the vehicle design of the main engine plant for the global market, and accelerate the import process of the global market of vehicles.

Power assisted electrification

Electrification and intelligence are becoming a new normal in the commercial vehicle industry. MBSP XBS can be deeply integrated with the electric drive system to significantly improve the energy recovery efficiency of electric vehicles and ensure the maximum utilization of energy by enhancing the synergy between regenerative braking and service braking.

It works effectively with ZF electric drive system to further optimize energy recovery, effectively reduce energy consumption and optimize total cost of ownership, so as to provide strong support for promoting the process of commercial vehicle electrification.
