Abstract

A fault-tolerant computer system (FTCS) for generating safe trajectories for a vehicle. The FTCS includes: a sensor part (SENSE), a primary part (PRIM), a secondary part (SEC), a tertiary part (TER), and a decide part (DECIDE). The PRIM and TER are configured to produce trajectories by interpreting information of the real world as perceived by the SENSE. The SEC is configured to produce a safe space estimate (FSE) by interpreting information of the real world as perceived by SENSE. The DECIDE and/or SEC are configured to execute correctness checks that take trajectories and FSE as inputs, and qualify a trajectory (TRJ) as safe when said TRJ is inside the FSE, and qualify a trajectory (UTRJ) as unsafe when said UTRJ is not inside the FSE.
