(NASDAQ: AMBA), an edge AI semiconductor company, today announced in advance of AutoSens Europe that its Oculii™ AI 4D imaging radar technology is deployed worldwide in the 2023 and 2024 Lotus Eletre electric hyper-SUV as well as the 2024 Lotus Emeya fully electric hyper-GT from Lotus Technology. The vehicles’ L2+ semi-autonomous systems that have benefited from this groundbreaking radar technology include highway and urban navigation on autopilot (NOA) and automatic emergency braking (AEB), where the ultra-long detection range of over 300 meters provides more time to safely react to vehicles and other objects while traveling at highway and racetrack speeds. These systems were developed by Lotus Robotics, a wholly owned subsidiary of Lotus, as part of its autonomous driving platform. Ambarella’s Oculii radar technology is providing ultra-fine angular resolution of one degree in both vehicles, using only six transmit and eight receive antennas on each of the vehicles’ two radar modules—more than double the resolution of the nearest 4D imaging radar competitor using the same number of antennas. This high angular resolution is important for clearly distinguishing, identifying and locating objects and people, both for nearby detection in crowded urban environments, as well as from a far distance when travelling at highway and racetrack speeds, to ensure timely and accurate avoidance and braking by the vehicles’ L2+ systems. This high resolution, in combination with a low antenna count, also provides higher value, while significantly reducing radar system power consumption and complexity; enabling the radar modules to be fitted into the desired locations on the vehicles. This combination can only be achieved using Ambarella’s Oculii AI radar algorithms, because of their unique ability to adapt radar waveforms to the environment. In fact, other 4D imaging radars require double the number of antennas to achieve the same level of performance, and in some cases, even more; leading to at least double the power consumption. “The performance that Lotus has achieved using our Oculii 4D imagin...
