Provide a full range of safe driving assistance services, clear wisdom, deep commercial vehicle ADAS product matrix

On November 1, 2019, the 2019 China International Commercial Vehicle Show was held at the Wuhan International Expo Center with the theme of “Intelligent Drive, Green Development”. It is the only national-level commercial vehicle exhibition in China and is currently the largest commercial vehicle in Asia. Car show. As the leading domestic commercial vehicle electronic component supplier, Qingzhi Technology participated in this exhibition for the first time, demonstrating the important products and future product planning in the commercial vehicle ADAS market. On the same day, Qingzhi Technology debuted at the China (Beijing) International Public Transportation Equipment and Technology Exhibition, demonstrating the smart terminal products and technical strength for the bus market.

With the core advantages of industrialized R&D ideas, environmental awareness and information fusion technology, more than 200,000 kilometers, and more than 120 kinds of Chinese roads measured in China, Qingzhi Technology has formed four current ADAS core products:

Automatic Emergency Brake System (AEBS)

The system calculates the braking distance required for man-made collision avoidance based on the front target information and the vehicle state, and calculates the collision safety margin based on the minimum braking distance of the vehicle. When the collision is about to occur, the driver still does not have any hedging. During operation, the vehicle cuts off the power output (the accelerator pedal does not work), no longer accepts the driver's acceleration control, and automatically brakes with full force to avoid or slow the collision.

Qingzhi AEBS

AEBS involves complex information sensing and control processes, and is highly integrated with the vehicle control system. The product technology threshold is extremely high. This is precisely the Qingzhi team that has a solid scientific research foundation.

Intelligent Security Control System (ISPS)

The product uses sensors to detect information such as the relative distance and relative speed of the vehicle or obstacle and the vehicle in front, and combines the information such as the driving speed of the vehicle and the posture of the vehicle to alarm and brake the potential danger, and assist the driver to improve the vehicle. safety.

Intelligent security control system

The system integrates collision mitigation system (CMS), anti-missing accelerator (EAPM), forward collision warning (FCW), pedestrian collision warning (PCW), lane departure warning (LDW), traffic sign recognition (TSR), and distance detection. Functions such as early warning (HMW) meet the new driving needs of commercial vehicle intelligence and safety. The collision mitigation function can effectively prevent secondary passengers from being injured after braking, and is more suitable for commercial passenger vehicles.

Electronic Stability System (ESC)

The system implements ESC product functions based on EBS (Electronic Brake System). Including ABS, EBD, ASR, HHC, RSC, ESC and other sub-functions. The system can combine the vehicle model according to the perceived result: in the starting or acceleration phase of the vehicle, through the power intervention and the active application of the braking torque of the sliding driving wheel, the purpose of driving the anti-skid is achieved, and the vehicle driving performance (ASR) is provided; During the normal braking phase of the vehicle, adjust the braking torque distribution of each axle wheel to achieve a more ideal and more stable braking effect (EBD); adjust the vehicle braking torque to prevent the wheel from locking when the braking force causes the wheel to lock up. To suppress the steering failure caused by the wheel lock or the condition of the vehicle's tail, improve the braking stability (ABS); when the vehicle turns to roll, suppress the driving force and implement active braking to reduce the rollover tendency and prevent Vehicle rollover (RSC); also helps to suppress oversteer and understeer by driving force control and brake intervention while driving, improving driving stability (ESC).

Electronic stability system

Intelligent terminal system

The system itself has sub-functions such as FCW/HMW/LDW/PCW/DSM/Front view DVR/GNSS/4G. During vehicle travel, the vehicle status is monitored and driver and vehicle status data is collected for data analysis. When the driver or the vehicle is insecure, give the driver a variety of sound and light warnings; when the vehicle finds an emergency in the cloud and the driver cannot control the vehicle, the vehicle can be remotely controlled to improve the system. The purpose of the internal vehicle is safe to operate. At the same time, when detecting the above various abnormal working conditions, the system can package the data and upload it to the cloud server in time for the subsequent data analysis, in addition to the various data of the specified time period before and after the local storage of the recording working condition. Evaluate with the driver. The cloud can also manually view real-time data information of vehicles through the system.

PT1.0 terminal

The system improves the monitoring mode and monitoring content of the driver state in the existing DSM system, improves the monitoring safety of the driver, and the system cloud can have the function of quickly taking over the control of the vehicle in an emergency situation, providing one A safer, more efficient and intelligent vehicle-assisted driving system solution to build a monitoring and assisted driving system with driving safety, vehicle controllability and transportation stability. The system can be used for freight vehicles with safety requirements as well as for large passenger vehicles.

Qingzhi Technology core products

Incoming card truck market, it is policy drive and even responsibility

On March 15 this year, the Ministry of Transport officially released the JT/T1242 2019 AEBS national standard: from April 1st, the new production of more than 9 meters of operating vehicles need to be installed with the required LDW (lane departure warning system) and AEB (Automatic Emergency Brake System), as one of the official drafting units of the standard, has been actively responding to policy deployment and has cooperated with commercial vehicle manufacturers. As of the end of October, some of the ADAS products of Qingzhi Technology have successfully passed the regulatory testing of 40 models of 10 bus manufacturers, and have achieved mass production and supply.

According to the "Technical Conditions for the Safety of Trucks" issued in 2018, from May 1, 2020, FCW and LDW should be installed for trucks and tractors with a total mass greater than or equal to 12,000 kg; total quality on May 1, 2021. For vehicles and tractors with a speed greater than or equal to 12,000 kg and a maximum speed of more than 90 km/h, an AEB is required. In the context of the introduction of national policies and local regulations, the mandatory installation node of the truck truck market has entered the countdown stage. At the same time, we can also see that with the rapid development of the logistics industry and the frequent occurrence of road traffic accidents, the demand for upgrading the safety and comfort configuration in the commercial vehicle market is gradually increasing, and there are market conditions for the start of matching ADAS products with strong equipment. In addition to supporting the country's mandatory installation policy, Qingzhi provides safe and reliable products for OEMs. Based on the idea of ​​positive development, on the basis of accelerating product iteration, it continues to expand the matrix of ADAS products, electronic stability system (ESC), and Products such as Adaptation Life (ACC) and Lane Keeping Assist (LKA) will be put into mass production, providing customers with customized and comprehensive safety driving assistance products.
