Safety and security of automated and autonomous vehicles
An important topic discussed during the World Forum for Harmonization of Vehicle Regulation (WP29) is
the safety and security of automated/autonomous vehicles of levels 3 and higher: during the session, the
commission identified key guidelines to be observed during the developement of this new innovative
vehicles. The following list shows all the issues and principles that aim to provide the general parameters
for work and to provide common definitions and guidance for further innovation in this field.
1. System safety: the automated vehicle should not put in risk other road users and ensure
compliance with road traffic regulations.
2. Failsafe Response: the automate/autonomous vehicle should be able to detect its failures or when
the conditions for the automated mode are not met anymore, being able to transition
automatically to a minimal risk situartion.
3. Human Machine Interface: the vehicle should include driver engagement monitoring, directly
requesting the involvement of the driver to regain a proper control of the vehicle when necessary.
Moreover, the vehicle should show its operational status to the other road users.
4. Object Event Detection and Response (OEDR)
5. Operational Design Domain (automated mode): the vehicle manufacturers should document the
ODD available on their vehicles and its functionality. The ODD should describe the specific
conditions under which the automated vehicle is intended to drive, including informations about
roadway type, geographic area, enviromental conditions etc.
6. Validation of System Safety: Vehicle manufacturers should demostrate a robust design and
validation process based on a systems-engineering approach with the goal of designing automated
driving systems free of unreasonable safety risks and ensuring compliance with road traffic
regulations and the principles listed in this document. Design and validation methods should
include a hazard analysis and safety risk assessment for Automated Driving System (ADS), for the
OEDR, but also for the overall vehicle design into which it is being integrated and when applicable,
for the broader transportation ecosystem. Design and validation methods should demonstrate the
behavioural competencies an Automated/autonomous vehicle would be expected to perform
during a normal operation, the performance during crash avoidance situations and the
performance of fall back strategies. Test approaches may include a combination of simulation, test
track and on road testing.
7. Cybersecurity: the vehicle should be protected against cyber-attacksand ensure that data is
traceable within a robust document version control enviroment
8. Software Updates: the vehicle manufacturers should ensure system updates and after-market
repairs and modification as needed
9. Event data recorder (EDR) and data storage system: the automated vehicles should have the
function that collects the necessary data related to system status, malfunctions and failures.
Other than the previous, more points are being discussed and listed as addidional issues, such as post-crash
behavior, vehicle maintenance and more.
