In today's automotive industry, the term autonomous driving is increasingly used. More car companies are striving to "go ashore", whether it is a traditional old car company or a new car-making force, they can't avoid the link of automatic driving, it seems that if they take a slow step, they will eliminate the inferior and stay good.
Although with the current technology, there is still a certain distance to achieve full automatic driving, but the automatic driving assistance system has entered the lives of more people, and many hundreds of thousands of models have even taken it as standard.
Achieving autonomous driving assistance requires several crucial parts. If the car is compared to a person, then radar and cameras are the "eyes" of the car; the computing computer is also the "brain"; the wheel, steering and power system are the "legs". If a person wants to achieve normal walking, all three are indispensable, and if a car wants to achieve automatic driving, these hardware must be complete.
Of these three, the most important one must be the "eye", because only by seeing the obstacles and the road environment can you drive. If there is no good "eye", it is empty talk to talk about others - because if safety cannot be guaranteed, who wants to take their lives for transportation?
At present, there are three kinds of mainstream automobile perception and reception equipment: camera, millimeter wave radar, and lidar. In the field of lidar, which is the latest and most technologically advanced, we have to mention Sagitar Juchuang, a real leading enterprise in the industry.
Why is lidar the strongest?
Before talking about Sagitar Juchuang, let's talk about the most advantageous lidar in the field of perception and see why it is an indispensable device for high-end automatic driving. As mentioned earlier, the current mainstream automobile perception and reception equipment includes cameras, millimeter wave radar, and lidar, and these three devices have their own advantages and disadvantages.
Tesla as a class of models using camera perception scheme, through the image algorithm and calculate the data, the advantage is low cost, car level camera CMOS size is so small, the price can be high? The disadvantages are also obvious, rainy days, black days, strong light and other line of sight obstruction, the camera's field of view will also be blocked, at the same time, the camera's perception of distance depth is also completely dependent on the algorithm, the algorithm encountered some obstacles that have not been "seen" are likely to be unable to distinguish - look at the number of accidents of Tesla driving assistance, I think you definitely do not want to hand yourself safely to a few cameras, right?
Millimeter-wave radar has also been widely used at present, and the advantages are obvious, the detection distance is long enough, and the interference with the environment is almost zero. The disadvantage is also obvious, the resolution of millimeter-wave radar is extremely low, and it is "blinded" when it encounters situations that need to be accurately identified. So in order to learn from each other's strengths, many models will combine millimeter wave radar with cameras, but the requirements for chip algorithms are high, in order to ensure that the computing power meets the requirements, many stationary items will not be counted, in some specific cases, the danger will occur!
Take a classic example. Above is a video of the accident taken by the driving recorder of the American owner Richard FS. On July 15, 2019, his Tesla Model 3 hit 11 construction isolation pile barrels in a row while driving on the highway, and finally stopped next to the road. In this accident, Tesla's 3-eye camera, millimeter-wave radar and more than a dozen ultrasonic radars throughout the body did not play any role at all.
Under the lessons of Tesla's predecessors, lidar as a sensor with high accuracy, high resolution and depth perception has naturally attracted the attention of car companies. Lidar can be unaffected by ambient light, by measuring the object's distance orientation, depth information, reflectivity, etc., accurately obtain high-resolution three-dimensional information. Coupled with AI perception software, obstacles around the vehicle can be identified, so that the vehicle has a better "eye view". See clearly, in order to open more steadily! Therefore, lidar has also become an indispensable part of high-level automatic driving functions.
Next, let's talk about Speed Tengjuchuang, why is it a leading enterprise? Quite simply, the lidar under the Sagitar Juchuang brand has taken the top seat in the domestic automotive front-loading market. The brands we are familiar with, such as BYD, GAC Aegean, WM, SAIC Zhiji, and Extreme Kr, all choose Sagitar Juchuang's second-generation intelligent solid-state lidar. Up to now, Sagitar Juchuang has obtained 40+ vehicle front-loading fixed-point model cooperation, which is the Chinese lidar enterprise with the largest number of fixed-point models in 2021.
All car flagships use it!
If we look at the current models equipped with Sagitar Juchuang RS-LiDAR-M1 (hereinafter referred to as: Sagitar Juchuang M1), such as AION LX, WM M7, etc., we will find a problem. Why did the flagships of various brands invariably choose Sagitar Juchuang M1?
When it comes to flagship models, many people's first impression is expensive, in addition to advanced technology. Flagship models also represent the strongest level of car building of each brand, so in terms of hardware, flagship models must use the best. Whether it is from the product configuration itself, or in the degree of advancedness of the vehicle's autonomous driving assistance function, as well as the hardware foundation provided for the vehicle OTA, the second generation of intelligent solid-state lidar is a better choice.
So if these brands want to choose the second generation of intelligent solid-state lidar, "unfortunately" only Sagitar Juchuang M1 can choose, Sagitar Juchuang M1 is also the only known on the market can do the second generation of intelligent solid-state lidar that can achieve mass production of vehicle specifications. For car companies, it is either to choose a generation of products, or to choose the second generation of products only Sagitar Juchuang M1. And flagship products, of course, can not be wronged by it, so can not do "multiple choice", must be "mandatory topics".
Where is Sagitar Juchuang M1?
The second generation of the second generation of intelligent solid-state lidar is not just talk, if you want to impress car companies, you must have real materials.
At present, solid-state lidar is divided into MEMS, OPA, Flash three schemes, and sagitar Juchuang's MEMS scheme is the use of microelectromechanical system micro-galvanometer for precise control of the laser, compared with OPA phased array and Flash surface array, MEMS is the most feasible solution for mass production.
The distance of the car detection not only affects safety, but also affects comfort. For example, if the speed of the vehicle is 120km/h cruising, then the detection distance of the vehicle must be higher than 85 meters, if it is lower than this value, in the event of an emergency, it is likely that there will be a rear-end collision and other traffic accidents; however, even if it is higher than 85 meters of detection distance, if it encounters a traffic jam or even a stationary object and other emergency stops, the vehicle will also brake urgently, which cannot ensure the comfort of the personnel in the car; to ensure a comfortable response distance, the vehicle detection distance will reach more than 160 meters. If the speed is higher than 120km/h, the comfortable response distance is longer.
The MEMS scheme of Sagitar Juchuang M1, with the far/near field "gaze" function of intelligent zoom, the obstacle detection ability can reach 200 meters, the performance is strong enough, and the vehicle can respond earlier and faster in the event of an emergency, which greatly ensures the safety of the vehicle and the comfort of the passengers in the car.
At the same time, sagitar Juchuang's self-developed two-dimensional MEMS chip scanning technology is more flexible in scanning methods, compared with the first generation of mechanical lidar, which greatly reduces laser components, and also eliminates the balance of the scanning motor.
Such a design makes Sagitar Juchuang M1 significantly reduce parts compared with the first generation of solid-state lidar, the cost is lower, the volume is smaller, the weight is only 730g, and the aesthetic degree after loading has also improved more than one grade, after all, no one wants to put a "small bucket" on the roof of their car.
At the same time, Sagitar Juchuang M1 also has a biggest advantage, that is, it has a very high yield rate, higher manufacturability, and the world's first automated production line, which also creates its achievements in rapid mass production. Sagitar Juchuang M1 has also completed vehicle specification level certification, including SGS and Goebel's Class1 eye safety certification, as well as IMDS, RoHS, REACH, FCC, CE and other product safety certification, sample testing has exceeded 800,000 hours and 2 million kilometers, and won several science and technology awards.
Preemptive strikes are stronger
The same is the lidar, there are huawei, DJI and other famous manufacturers in research and development, why sagitar Juchuang energy first completed the second generation of intelligent solid-state lidar mass production? Is it because of the core technology?
I think that the core technology is only one of them, and the bigger factor is the strategic prediction of Sagitar Juchuang. For the rise of the vehicle-mounted lidar market, Sagitar Juchuang had a preliminary judgment in 2016, and after 5 years of research and development iteration, it became the earliest vehicle-grade solid-state lidar enterprise in China. Similar to BYD's dominance in the field of electric vehicles and the Ningde generation in the field of lithium batteries, they all came earlier and had the opportunity to preemptively attack.
Sagitar Juchuang was officially established in 2014, and in 2016, when millimeter-wave radar was not yet popular, Sagitar Juchuang had mastered the core technology of lidar, and at the end of the year, the focus of research and development shifted to the second generation of intelligent solid-state lidar. In the same year, lidar was not even mentioned in many people's dictionaries.
In July 2020, Sagitar Juchuang obtained a fixed-point order from the North American luxury new energy vehicle company Lucid; in 2021, GAC Aeon, Alibaba, WM, JiKr, BYD, etc. all announced cooperation with Sagitar Juchuang, which is the first year of M1's real mass production. Not only in the field of passenger cars, Sagitar Juchuang has a high reputation in the fields of commercial vehicles, commercial robots, unmanned logistics vehicles, etc., and also has a wide range of strategic partners. It is reported that at the end of this year, after the completion of all production lines of Sagitar Juchuang M1, the annual production capacity will reach one million units.
As of September 2021, Sagitar Juchuang's automotive front-loading market has accounted for 10% of the global market, ranking first in China and second in the world. In the future, with the expansion of the scale of autonomous driving, the lidar market prospects will be broader, by 2026 is expected to reach 5.7 billion US dollars, 2030 is expected to automatic driving-related new car sales and travel services to generate more than 500 billion US dollars, there is no doubt that Sagitar Juchuang will take a large piece on this "big cake", and may even be the largest piece.
