China, October 19, 2020 – ams AG (SIX: AMS), a leading global provider of high-performance sensor solutions, announced that it is an expert in automotive LiDAR sensor technology and related software. and global technology leader Ibeo Automotive Systems GmbH, the latest ibeoNEXT Solid-state LiDAR solution uses ams’ Vertical Cavity Surface Emitting Laser (VCSEL) technology as a core component. This industry-leading LiDAR system from Ibeo will be used in Great Wall Motor’s future self-driving cars.

With two decades of experience in the automotive sector (including ISO 26262) and a deep presence in 3D consumer electronics, ams is an industry leader in VCSEL technology. VCSEL arrays from ams have excellent power density, conversion efficiency and pitch. The high reliability of the solution is achieved by integrating functional safety standards to provide enhanced functionality and eye protection. The VCSEL technology optimized by ams for this purpose allows great flexibility in layout design, including pixel size, dimensions and pitch, as well as specific addressable functions. In addition, ams has the capabilities required to jointly develop transmitters, current drivers and optics. The company’s high-power VCSELs excel in scanning and flood-array lidar applications because they are less susceptible to single transmitter failure, more stable over operating temperature, and easier to integrate.

Ibeo’s flagship version, ibeoNEXT, will be used in Great Wall’s future mass-produced vehicles—providing highway navigation and enabling Level 3 autonomous driving. ibeoNEXT further solidifies the company’s technological leadership in LiDAR sensors. The ibeoNEXT solid-state lidar provides an excellent large detection range, high resolution and large vertical angle. Combining its expertise in software and technology, Ibeo’s solid-state lidar sensor is a major milestone on the road to fully autonomous driving.

LiDAR systems emit laser pulses and then receive light reflected from various objects. The software calculates the distance to the target object using the so-called time-of-flight (ToF) principle, the time it takes for a reflected laser pulse to reach the sensor. Modern LiDAR systems can process many laser pulses in parallel: the result is a 3D model of the environment that recognizes crash barriers and road signs, vehicles, cyclists, pedestrians, and their positions and movements. This precision, coupled with long range and high spatial resolution, is a key advantage of LiDAR technology. Unlike other LiDARs, this solid-state solution has no moving parts, such as mechanical or MEMS mirrors, to control the scanning of the beam. So it has great advantages in terms of reliability and complexity.
