The International Organization for Standardization (ISO) approved ISO 22179:2009 - Intelligent transport systems - Full speed range adaptive cruise control (FSRA) systems - Performance requirements and test procedures.
The standard details how to automatically maintain a safe distance from the car ahead, regardless of its speed.
The new standard covers the following aspects:
- Basic control strategy.
- Minimum functionality requirements.
- Basic driver interface elements.
- Minimum requirements for diagnostics and reaction to failure.
- Performance test procedures.
FSRA technology improves the function of standard cruise control by adjusting the vehicle speed and distance to the vehicle ahead without any action on the part of the driver. If needed, the system will slow the vehicle down to a standstill.
Once the road is clear, the system will re-accelerate the vehicle back to the set speed. The system applies to highway driving, both under free-flowing and congested traffic conditions.
"Conventional cruise control is very useful, but can become a source of irritation when used in moderate or heavy traffic," said Yoshimi Furukawa, convenor of the ISO working group that developed the standard.
"Traffic conditions can change quickly from slowing vehicles or close cut-ins by other vehicles," Furukawa said. "The FSRA not only takes action when the distance to the vehicle in front changes, it also resumes the speed when the road is clear."
ISO 22179:2009 was developed by ISO technical committee ISO/TC 204, Intelligent transport systems.
