ISO Standard for cruise control systems promises safer driving

Ever driven a long distance using your cruise control and still felt tired and stressed from constantly having to adjust the vehicle speed to match traffic flow? An ISO international Standard for full speed range adaptive cruise control is expected to reduce driver fatigue and stress on long commutes by automatically maintaining a safe distance from the car ahead regardless of its speed.

Intelligent transport systems – Full speed range adaptive cruise control (FSRA) systems – Performance requirements and test procedures ISO 22179:2009 will improve safety for all highway users by automatically adjusting vehicle speed and, in so doing, enhance driving comfort and convenience.

Full speed range adaptive cruise control (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,' says 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. 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.'
