Safety and cybersecurity analysis of an autonomous shuttle

How do autonomous shuttles address safety and cyber security threats?

Autonomous vehicles are associated with new risks compared to conventional vehicles. These risks are due to the fact that the system must replace the driver’s decision making. This approach is very effective as long as the functioning of the system is provided in a safe and secure manner. To address this challenge, the International Organization for Standardization (ISO) has proposed ISO 26262, “Road vehicles – functional safety”. The project aimed to apply ISO 26262 to the development of autonomous vehicles and to couple functional safety with cyber security issues.

ROSAS, a partner of SwissMoves, completed this challenging and innovative project thanks to its knowledge in safety and security, and thus gained experience through one of the most advanced autonomous shuttles in the world.

The aim of the project was to apply functional safety techniques on critical vehicle systems and then to identify the safety levels and safety mechanisms adapted to the vehicle.

Within the framework of this project, ROSAS has carried out the following:

– Definition of the safety functions to be activated in a critical scenario to prevent accidents and damages.

– Identification of the critical risks/hazards concerning the different operating modes of the shuttle due to electronic and software failures.

– Calculation of the Automotive Safety Integrity Level (ASIL) based on the critical risks and failure consequences.

– Identification of functional safety requirements to be considered when developing critical systems.

– Cybersecurity requirements for external interfaces such as GPS.

– Functional safety concept to illustrate how the shuttle could be technically safe in a critical scenario. Distribution of safety requirements across the system architecture.

These elements were applied to the following Shuttle systems:

– Autonomous steering system

– Braking systems, including the emergency braking system

– Communication, navigation and monitoring systems

– Transmission and power systems

– Door system
