When it comes to "safety redundancy", many truck drivers will be as worried as journalists. In fact, at the technical level, the so-called "redundancy" refers to the adoption of two or more sets of relatively independent configurations to increase reliability. “Safety redundancy†means that the safety of the vehicle can still be guaranteed by the backup system or device to ensure the failure of the vehicle system. This is especially important for commercial vehicles, especially trucks with high risk of driving. . Mentioning "smart redundancy" has to mention the one-year brand that has been working with global car companies - Knorr. Based on years of technical precipitation in the braking system and the horizontal and vertical dynamic control systems of the vehicle, Knorr-Bremse is the first to propose an intelligent redundancy solution in the commercial vehicle field, making smart driving safer.
Knorr-Bremse Commercial Vehicle System (China) held a media meeting
On January 17, 2019, Knorr-Bremse Commercial Vehicles China 2019 media meeting was officially held in Shanghai. At the meeting, the brake system company, which was founded in 1905 and has a century of experience, gave a grand introduction to its outstanding achievements in ADAS. “When the vehicle is at high speed, if there is an emergency, the vehicle can recognize the vehicle ahead and automatically stop without collision when no one is involved. It is an important intelligent upgrade for vehicle safety. Knorr is the first to achieve in the truck and The AEBS on the bus achieves 80km/h to 0 for stationary targets, and the brakes are successfully stopped without collision.†Mr. Sander, vice president of strategy and business development of Knorr-Bremse Commercial Vehicles, said.
China's first innovation to introduce data fusion
Since 1972, Knorr-Bremse has been committed to the research and upgrade of vehicle control systems and automated driving related technologies. It has realized the application and promotion of technologies such as ABS, EBS, ESP, AEBS and LDWS. At the same time, the successful application of these technologies also laid the foundation for Knorr-Bremse's achievements in ADAS and automated driving. According to Mr. Sander, the new generation of global platform-based Brake Control System (GSBC) breaks the existing ABS and EBS system architecture and integrates the two to provide a customized system that can satisfy the global vehicle based on the same platform. Let the vehicle have a simpler system layout.
A detailed description of Knorr-Bremse's leading, innovative and localized technology
According to Mr. Sander, at present, the overall control process of Knorr-Bremse Autopilot system can be roughly divided into three stages: perception, decision-making and execution. Among them, Knorr-Bremse's unique radar and camera data fusion technology makes the environment recognition more precise. Greatly reduce the probability of false alarms during work. “Data fusion enables relatively more accurate identification of low-speed or stationary objects, thus enabling a stoppage,†Mr. Sander introduced. It is worth mentioning that Knorr was originally a company that started with pneumatic brakes. Therefore, Knorr-Bremse is superior to its counterparts in the integration of brake system, vehicle longitudinal control system and steering system, and further enhances users. Safety of vehicle operation.
Start with safety, not just safety
To solve the problem, we must find the pain point and solve it once. At the scene of the event, an old driver expressed the voice of all truck drivers in the most pristine language. "What energy saving and emission reduction, what is cost-effective and effective? It is secondary. What I want, but when there is a situation, I have a foot. Brake, the car can stop. Nothing is safe to be important."
Knorr-Bremse Vehicle Control System Products
Tens of thousands of reasons for a user's safety, Knorr-Bremse has been committed to safe transportation since its founding in 1905, whether in the braking system, steering system or autonomous driving, Knorr-Bremse always adheres to the quality first, zero tolerance of defects In principle, we have vigorously promoted technological innovation and research and development. Now we have been recognized by more than 30 countries and regions in the world for our excellent product quality. We have established more than 100 branches around the world and become the world's largest brake system company.
In the field of automated driving, Knorr-Bremse has already begun to lay out. While continuing research and development and increasing technical preparations, Knorr-Bremse has also continuously improved its own development system through cooperation and mergers and acquisitions. In 2016, Knorr-Bremse's acquisition of tedrive steering system company achieved business expansion in the field of vehicle lateral control, and has intelligent hydraulic steering assisted iHSA® products. iHSA® has the superior features of superimposed torque for greater comfort and safety. However, in view of the complex environment of the medium and heavy trucks, the working conditions are more dangerous, and the requirements for the diversity and accuracy of the intelligent system algorithms are higher. At the same time, Mr. Sander said, “At present, the AEBS system is still an intelligent auxiliary system. If the automatic driving is divided into 6 levels like 0-5, then the first three levels are in the intelligent auxiliary stage, that is, the driver is still needed. Human intervention. In the latter three stages, the system responsibility will be gradually transferred from the driver to the vehicle to achieve true automated driving. This requires an intelligent redundant system to cope with the situation of a system failure, which is qualitative with ADAS. Differently, the realization of the latter is also one of the directions that Knorr-Brem will strive to pursue in the future."
“Making Mobility Safer†Knorr-Bremse's daily mission
There was a sentence at the meeting that impressed the reporter. That was the "Making Mobility Safer" Knorr-Bremse's daily mission (making the traffic safer is the Knorr Group's purpose). It can be said that whether in the rail transit system or in the commercial vehicle transportation system, Knorr-Bremse has brought safe transportation to all parts of the world with its international team, rich technical reserves and excellent products. Not just safety, Knorr is always on the road for safer traffic!
