科技日报：打压中国产品难掩美国激光雷达产业窘境

Group 1 - The U.S. House of Representatives' "China Task Force" has proposed the "Laser Radar Security Act," aiming to phase out Chinese-made laser radars in the U.S. and ban imports after three years, except for research and cybersecurity testing [1] - The act's proponent, Congressman Raja Krishnamoorthi, claims that Chinese laser radars pose a national security threat and emphasizes the need for the U.S. and its allies to lead in laser radar innovation [1] - Chinese companies currently dominate the laser radar market, with estimates indicating that four firms—Hesai Technology, RoboSense, Huawei, and TuSimple—will hold 88% of the global market share by 2024 [1] Group 2 - Chinese laser radar companies are excelling in both technology and manufacturing, with Hesai Technology and RoboSense holding over three times the number of relevant patents compared to U.S. leaders Ouster and Luminar [2] - The mass production capabilities of Chinese firms are highlighted, with Hesai's automated production line producing a laser radar every 20 seconds and achieving competitive pricing, with some products priced as low as $200 [2] Group 3 - U.S. companies once held a leading position in the laser radar market, with Velodyne dominating with over 80% market share in the 2010s, but have struggled with low-cost mass production [3] - Recent challenges include the bankruptcy of Luminar, which was once highly valued, and difficulties faced by other U.S. laser radar companies, with Ouster's actual shipments being only 7,200 units in Q3 2025 [3] Group 4 - The struggles of the U.S. laser radar industry reflect broader issues within its manufacturing sector, suggesting that relying on market restrictions against Chinese products may not resolve underlying challenges [4]
