What is ISO/TR 21959‑1 about?
ISO/TR 21959 is a series of international standards on automatic road vehicles to check human performance while automated driving.
ISO/TR 21959‑1 is the first part of the ISO/TR 21959 series of documents that is applicable to automated driving of road vehicles and driver performance which help the user get knowledge of and attitudes toward driving automation systems.
ISO/TR 21959‑1 introduces basic common underlying concepts related to driver performance and state in the context of automated driving. The concepts are applicable to all levels of automated driving functions that require a human/driver to be engaged or fallback ready. ISO/TR 21959‑1 can also be used with levels that enable a driver to resume manual control of the vehicle.
NOTE: ISO/TR 21959‑1 can be applicable for human factors assessment/evaluations using driving simulators tests on restricted roadways (e.g., test tracks), or tests on public roads. The information applies to all vehicle categories.
Who is ISO/TR 21959‑1 for?
ISO/TR 21959‑1 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 21959‑1?
Although automation technology is advancing at a very fast pace, most automated driving levels still require a human to fulfil specific driving tasks while being in automated driving mode.
ISO/TR 21959‑1 provides common underlying concepts for human performance and state for the researchers and developers of driving automation systems in order to facilitate the sharing of information and knowledge as these systems are developed and deployed.
Also describes the two aspects of human performance which include transition from manual to automated driving and transition from automated to manual driving.
ISO/TR 21959‑1 introduces a basic structure for how to think about driver states in the context of automated driving.
Driver readiness and availability are defined during automated driving that influences successive driver’s intervention performance to regain control of the vehicle from the system to continue driving manually, avoid a hazard or bring the vehicle to the minimum risk condition.
Furthermore, ISO/TR 21959-1 allows you to comprehend the idea of human performance while driving an automated vehicle, allowing users to think about how the automated vehicle behaves and enables its operating mode awareness.
