Architectural requirements for integrating external wireless sidelink telemetry directly into vehicle steering and braking loops.
Automotive safety standards traditionally assumed that all inputs to safety-critical actuators (brakes, steering) originated from internal, physical sensors wired to the CAN/Ethernet bus. Feeding external wireless V2X packets directly into steering actuators introduces unprecedented functional safety risks.
SafeV2X introduces an ASIL-D certified safety envelope. Wireless packets are isolated in an untrusted sandbox, verified against strict kinematic plausibility boundaries, and cross-evaluated across dual diverse lockstep processing cores before generating actuation commands. ``` +-----------------------+ Raw Sidelink +-----------------------+ | Untrusted V2X Radio | --------------------------------> | SafeV2X Sandbox Core | | (Physical Air Interface)| | Plausibility Checker | +-----------------------+ +-----------------------+ | v ASIL-D Lockstep Bus Brake / Steer Authority ```
Under over 10 million simulated fault injection cycles, SafeV2X demonstrated zero unhandled single-point faults and achieved complete fail-operational continuity.
