ISO 26262 ASIL D Radar Supervision & Emergency Braking in ISACSafe

Autonomous mobility and industrial robotics cannot compromise on safety integrity. When radar sensing and wireless telemetry share the same RF hardware and baseband processing pipelines, hardware faults or software latency could lead to catastrophic collisions. ISACSafe establishes deterministic, fail-operational supervisory channels with sub-millisecond automated emergency braking interlocks.

Core Engineering Areas

ISO 26262 ASIL D Lockstep Baseband Architecture and Hardware Supervision — Hardware architectures implementing redundant dual-core lockstep processing and online diagnostic coverage exceeding 99% for safety-critical ISAC systems.
Sub-Millisecond Radar-Actuated Emergency Braking (AEB) Interlock — Direct hardware coupling between dual-function radar echo detection pipelines and electro-mechanical brake-by-wire actuators for zero-jitter safety reaction.
Fail-Operational Antenna Array Beamforming and Graceful Degradation — Preserving radar angular resolution and telemetry throughput during partial hardware failure across multi-element active phased array transceivers.
