Autonomous vehicle safety control system and methods
The patent US12043287B2 describes a sophisticated vehicle system designed to enhance autonomous driving capabilities through a dual control unit architecture. The system comprises a first control unit and a second control unit, each receiving inputs from their respective sensing units, navigation systems, and an object detection electronic control unit (ECU). These control units generate distinct control commands that inform the vehicle's operating mode, which can include a default mode, a mode for pulling over, an immediate stop mode, or a gentle stop mode. The processor within the system is responsible for selecting and switching between these modes based on the health status of the vehicle and its autopilot units, ensuring safe operation under various conditions.
Additionally, the patent outlines methods for determining the health of the vehicle and its autopilot units, utilizing threshold values based on error or warning messages. The system is equipped with multiple power sources and ignition signals to support the operation of both control units. In scenarios where an error is detected in the first control command, the second control unit can generate an alternative command based on its own sensor inputs. This redundancy aims to maintain operational integrity and safety, allowing the vehicle to adapt its behavior according to the health status of its components. Overall, the patent presents a comprehensive approach to vehicle control that prioritizes safety and reliability in autonomous driving systems.
