Recently, JAC Group held a centralized display of its core intelligent technology achievements during the celebration of its 60th anniversary. During this period, Geometry, a partner working hand in hand with JAC Group, also had a "show of style" with its overall intelligent driving solution built around the "vision + 4D millimeter wave imaging radar" dual-dimensional heterogeneous information fusion perception technology route.

How this technology route is currently developing, what is the technical logic behind it, and whether it can become a new breakthrough solution for OEMs in the future have become the focus of heated discussion in the current industry.

In recent years, the discussion on the "pure vision" perception route has remained hot, but at the same time, facing the trend of intelligent driving gradually evolving towards a higher level, the multi-sensor fusion perception technology route has become more and more a consensus in the industry. Although each type of sensor has its own advantages, it has to be admitted that the performance of a single sensor in complex scenarios has certain limitations, especially high-level intelligent driving requires vehicles to have the ability to cope with extreme weather and all-weather complex environments. Only by using the information complementarity and iterative development of different sensors such as cameras, millimeter-wave radars, lidars, and ultrasonic radars can the robustness and safety of the perception system be improved.

How to combine these sensors to achieve the best effect? ​​The current mainstream solutions in the industry are mainly the following two: one is "vision + lidar + ultrasound", and the other is the combination of "vision + 4D millimeter wave imaging radar".

As a high-tech enterprise and specialized enterprise deeply engaged in intelligent driving technology, Geometry Partners has been adhering to the mission of "providing safe and effective methods for large-scale mass production of intelligent/autonomous driving and connected vehicles" for 5 years since its establishment. Starting from solving the pain points such as perception bottlenecks faced in complex intelligent driving scenarios, it has developed a high-resolution 4D millimeter-wave imaging radar, combined with vision, and designed a "vision + 4D millimeter-wave imaging radar" two-dimensional heterogeneous information fusion perception technology route to create an intelligent driving solution with differentiated advantages of " multimodal, all-weather, low-cost, and easy to mass produce ", achieving better performance and better driving experience. A series of high-end intelligent driving functions such as city NOA , intercity NOA, memory driving, memory parking, and autonomous valet parking have successfully entered the vision of many OEMs.

Among them, the result of the joint development of Geometry Partners with JAC Group based on its needs - a high-level driving assistance system with urban NOA as the core function , based on the 11V6R system solution and high-level intelligent driving algorithm and all-round safety redundancy strategy, which can not only cope with conventional NOA scenarios, but also safely and efficiently handle complex working conditions such as left-right turn games, mixed traffic of people and vehicles, avoiding vehicles cutting in, special-shaped obstacles, and ghost heads. In addition, the system expands the adaptability of intelligent driving application scenarios to all-day and all-weather range, and can realize driving and parking functions in various complex weather conditions such as rain, snow, fog and haze, bringing users a better urban NOA experience.
