Method and device for the control of a safety-relevant process and transportation vehicle

This invention describes a safety system for controlling critical processes, specifically in the steering of an autonomous vehicle. It uses at least two independent microcontrollers, each with its own sensor, to monitor and control the steering. The microcontrollers compare their sensor data; if they disagree, they vote to identify the faulty data and then disable the control from the problematic branch, ensuring continued safe operation. The claims narrow this to systems using rotor position sensors to detect the angle of an electric motor's rotor.

Why it matters: Filed before widespread L3/L4 autonomous vehicle deployment, the period since 2019 has seen significant advancements in autonomous vehicle development and the increasing stringency of functional safety standards. This makes robust, fault-tolerant steering control systems, which this patent addresses, more critical for commercial deployment.
