One of the patents I am most proud of in autonomous driving is now pending.To understand it, you first need to understand the statistical view of the world described in the DOGMA paper, authored by my former coworkers:
https://lnkd.in/g8tHnar9Once you grasp this, you understand the fundamentals of how to build a system that provides the autonomous-driving stack with a statistical model of the environment around the car, allowing you to quantify how reliable the statistics are for every single volumetric cell (âcubeâ) in Î-space around the vehicle.This approach is extremely powerful for sensor fusion: combining multiple LiDARs, radars, and cameras while explicitly reasoning about the reliability of each measurement. It can significantly reduce well-known side effects of LiDARs and radars such as highly reflective surfaces because those measurements are statistically weak and therefore down-weighted.However, this typically requires a large and expensive LiDAR setup, like the one used by Waymo.The new pending patent takes a different approach. It uses a set of fixed, single-point LiDARs, roughly $2 devices. When arranged properly, these sensors re-increase the statistical confidence along entire lines of volumetric cells by introducing additional independent measurements. This dramatically reduces the number of expensive LiDAR units needed by replacing them with far more affordable ones, while preserving statistical robustness.And yes, the patent also references an EQXX-like shape, the current record holder for EV range:
https://lnkd.in/gg4QnXJn(I am genuinely in love with this car, and I hope Mercedes-Benz will one day produce it commercially.)Importantly, this sensor fusion is not intended to directly drive the car. Its purpose is to verify the trajectories proposed by the machine-learning driving stack and to reject any trajectory that does not meet a confidence threshold of 1 chance in 100 million of being wrong (100Ă ISO 26262).To perform this work end-to-end, you need very special hardware. A GPU is not suitable here: burning 300 W while carrying severe safety limitations makes it fundamentally incompatible with this level of reliability.The full patent portfolio will be published in 2026.I hope youâll enjoy the ride.

Can you utilise other hardware yet which utilises less power? Maybe something neuromorphic?

François Piednoel de Normandie so the stack works independent of the processor controlling it. Thatâs very helpful

Kieran Ryan , no, we avoid any non-deterministic solution, as it is what is used to certify the safety side of our hardware + software.
