Entering 2022, the intelligent driving track will continue to be hot.Acceleration and upgrade are still the two key words on the intelligent track.

We have also seen that in the past 2021, in addition to Tesla, Weilai, Xiaopeng and other new forces, Beiqi Jihu, Geely Jikr, SAIC Zhiji, Great Wall Mocha, etc. have all launched their ownPilot Assisted Driving System.A market battle for the next generation of high-end intelligent driving solutions has quietly started, and at the same time, new opportunities and opportunities have been released for upstream suppliers in the industry.

In China, high computing power chips, domain control, lidar, and 4D imaging radar have become the must-have options for a new generation of intelligent vehicles, and they are fully preparing for the blank market for high-level autonomous driving.

Among them, the addition of 4D imaging radar means that machine learning technology can also use data from radar and fuse with other sensor data to improve the accuracy of perception.

At present, some companies have seized market opportunities.Including Continental Group, ZF, Aoku, etc., the first batch production designation and delivery are in progress.But there are only a handful of Tier 1s that really have the mass production capability of multi-sensor fusion.

In China, Freetech, with its full-stack technology capabilities and large-scale ADAS mass production experience, took the lead in catching the first train of 4D outlet, becoming the first Tier 1 enterprise in China to launch fixed-point mass production of 4D millimeter-wave radar.The related models are expected to be put into mass production by the end of the year.

As a leader in China's mass-produced autonomous driving technology, Freetech has self-research capabilities of intelligent driving technology from perception, planning to control execution, from demand decomposition, algorithm development, software implementation to system integration, to meet the needs of OEMs.Consumers with different styles have different needs for intelligent driving.

Relevant person in charge of Freetech said that in the advanced autonomous driving scheme, the introduction of 4D imaging millimeter-wave radar can not only improve the confidence of a single radar in the fusion of forward sensing targets, but also improve the radar's ability to move at low speeds.The accuracy of target and stationary vehicle and pedestrian recognition covers more specific scene perception needs in high-speed and urban areas.

At the same time, with the improvement of the level of automatic driving and the upgrade of functions, the domain controller, as the central computing center, has put forward higher requirements for the perception performance of millimeter-wave radar.At present, the advantages of 4D front radar in angular accuracy and angular resolution are reflected in complex scenes:

Compared with traditional millimeter-wave radars, Freetech imaging radars use more transmit and receive channels to achieve a geometrical increase in the number of virtual channels.Resolution accuracy and point cloud density have been significantly improved. With the overall improvement of perception performance, 4D imaging millimeter-wave radar will become an indispensable part of high-level autonomous driving.

For example, in the mass production development, the Freetech domain controller needs the information of the target vehicle's driving lane offset position 200 meters in front of the vehicle to make decisions. The azimuth accuracy of the traditional front radar is about 0.3 degrees.Lowering the lane of the target vehicle will cause a large position error, and the true deviation of the target vehicle cannot be accurately judged.The azimuth accuracy of the 4D imaging radar can reach 0.1 degrees, which is 3 times higher than the traditional front radar azimuth, and can output more accurate vehicle lane offset information at 200 meters to the domain controller;

If the information of two target vehicles, large and small, driving side by side at a distance of 100 meters in front of the vehicle is required, the azimuth angle resolution of the traditional front radar is about 3 degrees, which will cause the information of the large and small vehicles in front of the scene to be indistinguishable, and the two vehicles will be mistakenly identified.The car is recognized as a target.The azimuth resolution of the 4D imaging radar can reach 1 degree, which is 3 times higher than that of the traditional front radar. In this scenario, the large and small vehicles can be divided into two targets and output to the domain controller;

When the Freetech domain controller needs information such as static crossbars, manhole covers, and ground obstacles in front of the vehicle to make decisions, the traditional front radar pitch angle accuracy is about 1 degree.There is a large error with the height information of ground obstacles.The 4D imaging radar pitch angle accuracy can reach 0.1 degrees, which is 10 times higher than the traditional front radar, and can output the accurate height information of obstacles to the domain controller;

If there are multiple stationary obstacles or people, the traditional front radar has no pitch angle resolution and cannot accurately distinguish people, obstacles and crossbars.The pitch angle resolution of Freetech 4D imaging radar can reach 1 degree, which can distinguish multiple target features and output them to the domain controller.

The Gaogong Intelligent Automobile Research Institute predicts that the 4D imaging radar will be introduced on a small scale from early next year.The proportion of wave radar is expected to exceed 40%.

From the perspective of technical solutions, as radar chip solution providers start a new wave of hardware technology iterative upgrades, new companies and traditional radar giants will be the first time in the next-generation high-resolution, 4D millimeter-wave imaging radar track.stand on the same starting line.

Whoever can reduce the cost to the greatest extent and solve the difficulties of mass production will have the opportunity to be the first to get the admission ticket to the "final circle" of high-end autonomous driving.

While the industry generally uses chip stacking to achieve high performance of radar, Freetech Radar has taken a different approach. Through the innovation of intelligent software algorithms and adaptive waveform design, the same amount of chips can be achieved with fewer chips.The radar effect of high performance greatly reduces the volume and cost, and at the same time effectively improves the reliability and stability of the product.
