Shanghai Auto Show Observation: What are the new things from suppliers (sensors)

From April 18 to 27, 2023, the 20th Shanghai International Auto Show will be officially held. Although the auto show has not yet arrived, the atmosphere is already heated.

As an important stage for colleagues in the automotive industry to display cutting-edge technological achievements and strategic planning, in addition to new car releases, suppliers who entered the auto show also brought many new gadgets of their own. Its actions in various fields of smart electric have attracted the attention of the entire industry.

Among them, the players of perception sensors are quite vocal, and many manufacturers related to millimeter-wave radar, lidar, and cameras have successively released warm-up content for the auto show.

Camera

With the development of smart cars, the importance of automotive perception systems has gradually increased. As one of the sensors with the oldest history and the most mature technology in the perception system, cameras are ushering in volume and price due to their low cost and the advantages of being complementary to other sensors. Opportunity to rise together.

At the Shanghai Auto Show, Ruichuang Microna will exhibit its full range of automotive infrared thermal imaging products, including Asens M6+, IR-Pilot 640X, Horus 640, etc., which are equipped with the first domestic infrared chip that has passed AEC-Q100 automotive grade certification. For automotive products, the IR-Pilot 1920X, an automotive infrared thermal imager equipped with the world's first 8μm 1920×1080 infrared thermal imaging chip, will also be unveiled simultaneously.

In addition, in addition to displaying new products such as the brake-by-wire system WCBS 2.0 and the dual-pinion electric power steering system, Wuhu Bethel will also display its high-precision positioning camera AFC 2.0 product for the first time at the Shanghai Auto Show.

Zhongke Huiyan will display a self-developed road surface preview full-stack functional prototype, which consists of a road surface preview system and a magnetorheological vibration reduction system.

According to Zhongke Huiyan, the system uses a binocular stereo vision camera as the main sensor. It can calculate the depth based on the images captured by the left and right cameras to achieve 3D reconstruction perception of the road surface. It can achieve the following six functions: road elevation detection, road surface target Detection, road impact excitation detection, all-terrain detection, height limit and width limit detection, chassis obstacle detection.

millimeter wave radar

Because of its strong penetrating power, all-weather use, and stable performance, millimeter-wave radar has become a powerful tool to make up for the functional deficiencies of other sensors such as lasers and cameras. Especially in recent years, the development of 4D millimeter-wave radar has become increasingly popular, and is considered to be another option to improve vehicle perception capabilities and move towards high-level autonomous driving.

At this auto show, Furuizhi will debut with its 4D radar series products. Previously, Fu Rui Intelligent Technology lit up China's first 4D millimeter wave radar equipped with TI2944 chip. It is reported that at this auto show, in addition to the Columbus series of 4-transmit and 4-receive radars released in 2022, the newly developed Picasso series of 6-transmit and 8-receive imaging radars and the Galileo series of 12-transmit and 16-receive imaging radars newly developed by Furuizhixing will also be at the exhibition site. First exposure.

In addition, Xingyidao will also hold a new 4D radar launch conference, which will bring products such as forward 4D imaging radar ALRR300, forward (with elevation classification, supporting AEB) radar AMRR200, upgraded angle radar ASRR220 and vehicle-mounted synthetic aperture imaging radar. this auto show.

Chuhang Technology will also bring a full line of fifth-generation mass-produced radar products and fifth-generation 4D imaging radar products, as well as its first innovative product in the industry - stealth radar. According to Chuhang Technology, this product breaks the physical limitations of millimeter wave radar and adopts the most cutting-edge radar technology.

lidar

When it comes to in-vehicle sensors, lidar is an unavoidable topic. Starting from 2021, car companies have gathered to announce that lidar will be "onboard". By 2022, many models equipped with lidar will begin mass production and delivery, and in 2023 It is considered to be the year when lidar will explode. As one of the industry trends in recent years, it cannot help but attract the attention of the industry.

During this auto show, Liangdao Intelligent will showcase lidar mass production system solutions and lidar-based smart city solutions, including the LD Satellite® lateral blinding LiDAR hardware and perception debuted at the auto show, and LD 5G mobile base stations.

According to Liangdao Intelligence, LD Satellite® is the first automotive-grade pure solid-state lateral blinding lidar in China. Its products adopt chip design and electronic scanning technology, without any moving parts inside; they have a large field of view and are compact in size. The LD 5G mobile base station is a set of mobileally deployed roadside sensing workstations. Equipped with sensing algorithms and a variety of post-processing tools, it can achieve real-time sensing and detection of traffic targets. Liangdao's data closed-loop map that supports AI algorithms will have its world premiere at this auto show.

Another lidar company, Yijing Technology, will display a full range of high-performance, integrated, small-sized, and mass-produced long- and short-range automotive-grade solid-state lidar products, including short-range lidar ML-30s+, ultra-long-range lidar LiDAR ML-Xs. At the auto show, Yijing Technology will demonstrate its various long-range + short-range LiDAR combination solutions on the new ZVISION ZERO CAR. This DEMO car will also demonstrate Yijing's systematic LiDAR engineering solution.

In addition, it is reported that manufacturers such as Tianmo Optoelectronics and Leishen Intelligence will release new lidar products at the Shanghai Auto Show.
