Hesai Technology, a firm specializing in lidar solutions for autonomous and assisted driving, announced Thursday that its AT128 lidar has been selected for multiple advanced driver assistance systems (ADASs), totaling several million units from firms including Li Auto, JiDU, HiPhi, and Lotus. The sensor model will begin mass production in the second half of 2022.
The first pure electric SUV Eletre was released on Wednesday, equipped with a deployable lidar system and advanced autonomous driving assistance technology.
The front and rear main lidars of the car are the AT128, a long-range hybrid solid-state lidar developed by Hesai Technology. The deployable lidar is designed to effectively reduce wind resistance while the driver is not using the autonomous driving function, which causes great challenges to minimizing the size of lidar itself.
According to Hesai Technology, the AT128 features an ultra-high measurement frequency of over 1.53 million points per second (single return), resulting in image-level resolution. AT128 also has a ranging capability of 200 meters at 10% reflectivity, with effective ground detection as far as 70 meters.
In addition, each AT128 incorporates 128 high-power multi-junction VCSEL arrays, enabling genuine 128-channel e-scanning. Hesai achieved the strongest comprehensive performance for AT128 among automotive-grade lidar sensors that have been mass-produced. The lidar sensor has dimensions of 137mm x 112mm x 47mm, which enables seamless integration with the vehicle.
