"臻" automatic driving under the concept of redundancy
For the future of autonomous driving, Knorr-Bremse has moved from braking systems to automated driving. Knorr-Bremse's ADAS system has been put into domestic commercial vehicles and passed relevant tests. The ADAS system now has an adaptive cruise control system (ACC), ACC automatic stop and driver start (Stop & Driver Go), automatic emergency braking system ( AEBS), Lane Keeping Assist (LKA) and Lane Departure Warning System (LDWS) functions. Thanks to the radar and camera data fusion capabilities, Knorr AEBS can achieve a collision-free target of 80km/h to 0 with more precise data acquisition.
Knorr autopilot parts In this exhibition, the redundancy concept of Knorr-Bremse's automatic driving system is one of its highlights. The concept of redundancy is important for the success of highly automated driving. Highly automated driving under the concept of intelligent redundancy will be more realistic and safe – even if the electronic subsystem fails, the system must have the function of preventing the vehicle from getting out of control. Knorr-Bremse's intelligent redundancy concept combines best-in-class performance with economic benefits. For example, Knorr-Bremse's steering redundancy concept demonstrates how to compensate for active steering system failures without having to repeatedly install the relevant components. In the future, autonomous driving, only when the entire system includes redundant architecture, the driver can be on the road to pay attention to other things as expected, to achieve higher efficiency and safer intelligent driving.
Full disk configuration, "soft and hard combination" of EBS and anti-tailing system
The overall configuration is the road to the development of Chinese vehicles in the future. Compared with drum brakes, disc brakes have a more stable braking torque, better resistance to thermal decay and speed decay, and better braking comfort. In addition, the disc brakes are lighter in weight, and the quality of the front axle for heavy-duty trucks can be reduced by about 20 kg, and the rear axle can be reduced by about 80 kg, which greatly improves transportation efficiency. At the same time, the disc brake has no self-increasing effect, the braking process is more comfortable and stable, and the driver's driving comfort is greatly improved.
Knorr pressure disc brake
Dangerous goods transportation has extremely high requirements for vehicle safety configuration. In Europe, semi-trailers with more than three axes must be equipped with EBS. The latest GB-7258 is also gradually upgrading the brake system configuration of hazardous chemicals vehicles. It is required that dangerous goods transport vehicles should be equipped with EBS, Electronic Stability System (ESP) and Lane Departure Warning System (LDWS) in the next few years. The disc brakes, EBS and trailer EBS are equipped to enable the vehicle to control the coupling force according to the load of the trailer, the speed of the vehicle and the acceleration, to solve the problem of mismatch of the main suspension of the vehicle, to prevent the phenomenon of folding and pushing the vehicle, and to make the vehicle run more. Safe and reliable.
Knorr trailer control module
The data shows that 20% of the major traffic accidents are caused by vehicle rear-end collisions. Knoll's radar detects the distance and velocity of the target in front of the journey and also detects the position and velocity relationship between multiple objects. Knorr-Bremse's unique radar and camera data fusion technology improves the accuracy of environmental recognition, prevents false alarms, and achieves driver assistance at level 2, namely automatic emergency braking (AEBS) and lane departure warning (LKA) ). The matching Knorr-Bremse automatic emergency braking system achieves 80 to 0 brakes and no collisions for stationary and moving targets. When the system detects that the vehicle has a deviation from the lane or has deviated from the lane, the LKA-ECU issues an instruction to the steering assist system, which will perform an active steering operation to maintain or return the vehicle to the lane. The combination of AEBS and LKA will greatly reduce the risk of vehicle rear-end collision and improve road safety.
Help the country's six air energy system "golden partner" to help
Knorr-Brem is currently the only supplier of air supply systems for system support. Air compressors and air handling units as a combination of systems provide customers with performance, quality and energy savings.
Knorr-Bremse Intelligent Air Handling Unit
In response to the National Sixth Standard, Knorr-Bremse has introduced a new 630cc air compressor with cylinder wall water-cooled, ultra-cold plate and ESS closed air chamber structure, with a discharge temperature as low as 150 ° C and an oil simmer as low as 0.3 g / h . Compared with the original model, it has higher air pumping capacity, lower oil consumption and lower exhaust temperature, and the energy saving effect is better.
The air handling unit includes a combined air dryer and an electrically controlled IAPU. The combined air dryer has the characteristics of strong oil filtering, high integration and strong water filtration. The integrated oil filter drying cylinder can achieve more than 95% oil filtering effect, and the maintenance period is extended from 50,000 kilometers to 100,000 kilometers. The electronically controlled IAPU is Knorr-Bremse's new generation of intelligent control air handling unit. The integrated ECU precisely controls the unloading pressure of the system to restore the supply pressure and regeneration flow. It can be optimized according to different application conditions to achieve optimal intelligent control to ensure the brake system is clean and efficient. Reduce energy waste.
At the same time, Knorr-Bremse's new generation 630cc air compressor and all-electric EAC constitute the world's leading air supply system, which can calculate the gas supply demand and gas distribution of the vehicle in the early stage of development. Choose a more suitable empty machine displacement, system pressure distribution and regeneration efficiency. The whole vehicle's pumping time is obviously shortened, and the poor working conditions such as long downhill have sufficient air supply capacity, and at the same time, it has obvious improvement effect of oil slick. The energy-saving aspect has passed the actual test, with at least 0.2L per 100 kilometers of oil saving effect.

SafetyDirector, a vehicle interconnection system, provides a future solution for the fleet
Kendall's Bendix vehicle connectivity system, SafetyDirect, provides an Internet-based security solution for large fleets. The specific features are:
Strengthening fleet safety management: The management of drivers' driving behaviors and dangerous events has become a consensus, and various post-installation schemes have emerged, but the accuracy of data is problematic.
Reduce the risk of vehicle operation: Targeted correction of irregular driving behavior, eliminate hidden dangers and reduce vehicle accidents.
Knorr-Bremse products are more digital
Front-loading reduces hardware costs: Radars and cameras installed with the AEBS solution do not require additional sensors or cameras. The front loading is safer and more reliable: the rear-loading market solution capacity and installation level are uneven, and the resulting vehicle safety problems are not uncommon, including failure to start, short circuit or even burning.
The responsibility for collecting evidence for the accident is clear: in some scenarios, it can act as a driving recorder to facilitate the investigation and evidence collection of the incident.
The SafetyDirect mode flexibly interfaces with the user's existing car networking system or forwards data. In the future, Knorr-Bremse will work with domestic suppliers to provide fleet management systems with vehicle networking capabilities to improve operational efficiency and reduce accident rates.
It is believed that after the debut of the Shanghai Auto Show, Knorr-Bremse will continue to coordinate research and development in the future of intelligent driving, providing more advanced and comprehensive system solutions for the automotive industry.
