On December 21, Huawei released automotive-grade high-performance lidar products and solutions for the industry for the first time. Huawei said that this lidar is more suitable for scenarios under complex road conditions in China. At present, Huawei has established the first Pilot production line of automotive-grade lidar, which is advancing with an annual output of 100,000 sets/line. This means that Huawei's lidar not only achieved a breakthrough from 0 to 1, but also crossed the threshold for mass production. 

    Huawei released 96-line medium and long-range lidar, which is more suitable for China's complex road conditions

    Duan Zhongyi, general manager of Huawei's Converged Sensing Product Department, said, "Lidar is a key sensor to solve the continuous autonomous driving experience, and the intelligent driving experience it brings will far exceed any commercial intelligent driving system."

    Compared with millimeter wave radars and cameras, lidars have excellent capabilities in target contour measurement, angle measurement, light stability, and general obstacle detection. Especially in difficult scenarios, such as non-standard pedestrians, non-standard roads, and even non-standard driving behavior in urban areas, Lidar is urgently needed to solve.

    The more laser radar lines, the higher the measurement accuracy and the higher the safety. At present, the released car-level mass-produced lidar is only 4 lines. The product released by Huawei this time is a 96-line medium and long-distance lidar. This radar can measure a distance of 200 meters and can detect pedestrians and vehicles in urban areas. It also has high-speed vehicle detection capabilities, which is more in line with China's complex road conditions.

    Specifically, this 96-line mid- and long-distance lidar product can achieve a wide field of view of 120°X25° to meet the demands of people and cars in urban areas, highways and other scenes. Not only that, in the full field of view, the horizontal and vertical harnesses are evenly distributed, there is no splicing, jitter, etc., forming a stable point cloud is very friendly to the back-end perception algorithm. In addition, the product is small in size, suitable for the needs of front-mounted mass-produced models.

    Manufactured according to vehicle-level requirements, Huawei sprints as a supplier of high-beam lidar

    In order for LiDAR to become a "car-regulated" product, "reliability" is one of the key conditions. For the high and low temperature and humidity, water pressure, vibration, salt spray, human eye safety, EMC (electromagnetic compatibility), gravel impact and other scenarios required by vehicle regulations, Huawei strictly implements the ISO international standards, even based on the special requirements of TOP car companies , Did more stringent tests. Huawei stated that it is confident of becoming the world's first supplier of high-wire-beam lidar with real car specifications.

    In response to the problem of lidar being covered by dirt, Huawei has developed an intelligent cleaning system. At present, Huawei has done a lot of tests to verify the cleaning effect of different nozzles, different positions, and different water pressures. Considering that cleaning is also required during driving, Huawei has also independently designed an intelligent cleaning wind tunnel system, which has realized the simulation application of cleaning at 130km/h, providing valuable insights for the next test of the impact of different nozzles and pressures on the cleaning effect. First-hand data.

    In addition to the intelligent cleaning system, Huawei has also developed an intelligent heating system. In scenes covered by frost, fog, condensation, and thin ice, the intelligent heating system built into the lidar will automatically start.

    Annual output of 100,000 sets/line, meeting the needs of millions of mass production

    If it meets the requirements of vehicle regulations and allows Huawei to achieve a breakthrough from 0 to 1, then the mass production of lidar will test whether Huawei can complete the leap from 1 to infinity.

    Relying on the precision manufacturing capabilities accumulated in the field of optical communications and advanced process equipment laboratories, Huawei quickly established the first pilot production line of automotive-grade lidar. Facing the demand for mass production at the level of one million, Huawei has been advancing with an annual output of 100,000 sets/line to meet future mass production needs.

    It is worth mentioning that on the day that Huawei released its lidar, BAIC New Energy’s high-end new energy brand ARCFOX Jihu announced that Jihu HBT will be the first smart electric vehicle equipped with Huawei’s three lidar solutions.
