摘要： A fault-tolerant computer system (FTCS) for generating safe trajectories (TRJ) for a vehicle (VEHICLE), wherein the fault-tolerant computer system (FTCS) comprises at least the following parts: a sensor part (SENSE), a primary part (PRIM), a secondary part (SEC), a tertiary part (TER), and an decide part (DECIDE), wherein the primary part (PRIM) and the tertiary part (TER) are configured to produce trajectories (TRJ, UTRJ) by interpreting information of the real world as perceived by the sensor part (SENSE), and wherein the secondary part (SEC) is configured to produce a safe space estimate (FSE) by interpreting information of the real world as perceived by the sensor part (SENSE), and wherein the decide part (DECIDE) and/or the secondary part (SEC) are configured to execute correctness checks that take trajectories (TRJ, UTRJ) and the safe space estimate (FSE) as an input, and qualify a trajectory (TRJ) taken for said correctness check as safe when said trajectory (TRJ) is inside the safe space estimate (FSE), and qualify a trajectory (UTRJ) taken for said correctness check as unsafe when said trajectory (UTRJ) is not inside the safe space estimate (FSE), wherein the sensor part (SENSE) or at least a part of said sensor part (SENSE) is developed according to an ASIL level of: QM, or ASIL A, or ASIL B, and the primary part (PRIM) is developed according to an ASIL level of: QM, or ASIL A, or ASIL B, and the secondary part (SEC) is developed according to an ASIL level of: ASIL B, or ASIL C, or ASIL D, and the tertiary part (TER) is developed according to an ASIL level of: ASIL B, or ASIL C, or ASIL D, and the decide part (DECIDE) of the fault-tolerant computer system FTCS is developed according to an ASIL level of: ASIL D.
