A Safety Interlock for Self-driving Cars

Daniel Jackson, Armando Solar-Lezama

An architecture is proposed to mitigate the risks of autonomous driving. To compensate for the risk of failure in complex components that involve planning and learning (and other functions whose reliability cannot be assured), a small number of trusted components are inserted as an interlock to oversee the behavior of the rest of the system. When incipient failure is detected, the interlock switches the system to a safe mode in which control reverts to a conservative regime to prevent an accident. The research will build on research in assurance cases from the field of software engineering and in probabilistic model checking from computer-aided verification.
