What is ISO/TR 21959‑2 about?
ISO/TR 21959 is a series of international standards on automatic road vehicles to check human performance while automated driving.
ISO/TR 21959‑2 is the second part of the ISO/TR 21959 series of documents that is applicable to automated driving of road vehicles in order to help users to evaluate takeover performance and design appropriate experiments to investigate transition processes.
ISO/TR 21959‑2 focuses on system-initiated and human-initiated transitions from a higher level to a lower level of automated driving. Human factors and system factors that can influence takeover performance are included.
Also includes information on considerations in test scenario design, common measures for human takeover performance, and considerations in choosing a testing environment.
Who is ISO/TR 21959‑2 for?
ISO/TR 21959‑2 on automated driving of road vehicles is useful for:
- Road vehicle designers and engineers
- Automated vehicles engineers and manufacturers
- Researchers and developers of driving automation systems
- Electric vehicle designers
- Automotive engineers
Why should you use ISO/TR 21959‑2?
Although automation technology is advancing at a rapid pace, most automated driving levels still require a human to fulfil specific driving tasks. ISO/TR 21959‑2 provides considerations in designing experiments to measure human takeover performance in transition situations to better understand human limitations, evaluate systems, and improve systems, including human-machine interfaces.
Also describes transition process models of automated driving both for system-initiated and human-initiated transitions.
There is a need to appropriately set systems and human factors as variables for investigating their effects or better controlling/eliminating their influence ISO/TR 21959‑2 provides systems and human factors that influence takeover performance.
Furthermore, while driving an automated vehicle, ISO/TR 21959-2 allows you to comprehend the concept of system-initiated and human-initiated transitions, allowing users to understand the safety-critical human task for improved takeover performance and enabling its operating mode awareness.
