Unsettled Issues in Drive-by-Wire and Automated Driving System
Availability EPR2022002
While many observers think that autonomy is right around the corner, there
many unsettled issues. One such issue is availability, or how the vehicle
behaves in the event of a failure of one of its systems such as those with
the latest “by-wire” technologies. Handling of failures at a technical actuation
level could involve many aspects, including time of operation after first fault,
function/performance after first fault, and exposure after first fault. All of
these and other issues are affected by software and electronic and mechanical hardware.
Drive-by-wire and Automated Driving System Availability discusses the necessary systems
approach required to address these issues. Establishing an industry path forward for
these topics will simplify system development and provide a framework for consistent
regulation and liability, which is an enabler for the launch of autonomous vehicles.
