Architecture for a driving assistance system with conditional automation

This invention describes a safety architecture for a driving assistance system with conditional automation, designed to control automatic emergency stops. It uses at least three types of sensors to monitor the road ahead, with a main computer processing this data to control the engine, brakes, and steering. Should the main computer fail, a backup computer takes over to control only the braking system, with both critical computers and the braking system having a backup power supply, all communicating via CAN networks.

Why it matters: Filed when conditional automation was nascent, the cost and performance of multi-technology sensors and robust vehicle control computers have significantly improved since 2016. This makes building such a redundant safety architecture more feasible and reliable today.
