Electric road vehicles – improved ISO safety Standard published
ISO has published an updated, improved edition of an international Standard that provides safety specifications for electrically propelled road vehicles. The two-part ISO 6469 will help manufacturers to design fail-safe electrically propelled vehicles.
ISO 6469 provides manufacturers with a framework for the information they need to make available for safety personnel and emergency responders dealing with accidents involving such vehicles.
'The new edition of this Standard will help to reduce the complexity of the relations between vehicle manufacturers and their suppliers,' says Dr Dietrich Sahm, Chair of the ISO technical committee that developed the Standard. 'ISO 6469.1:2009 and ISO 6469.2:2009 provide answers in a rapidly evolving technology and to an increasing public interest in the safety and environmental performance of electrically propelled road vehicles.'
Part 3 of ISO 6469 is currently under draft international Standard-Ballot (DIS) and specifies requirements for the electric propulsion systems and conductively connected auxiliary systems for the protection of persons inside and outside of an electric vehicle.
- ISO 6469-1:2009 Electrically propelled road vehicles – Safety specifications – Part 1: On-board rechargeable energy storage system (RESS)
- ISO 6469-2:2009 Electrically propelled road vehicles – Safety specifications – Part 2: Vehicle operational safety means and protection against failures
New 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.'
New ISO Standard on automatic road safety and emergency messages will get help to victims quicker
When a road crash occurs, a rapid medical response can often mean the difference between life and death for the victims. To help emergency centres dispatch the appropriate life-saving staff and equipment to crash scenes faster, a new international ISO Standard will help to ensure that automatic safety-related messages from the vehicle are immediately understood by emergency services.
Intelligent transport systems – ITS Safety and emergency messages using any available wireless media – Data registry procedures ISO 24978:2009 enables relevant parties to immediately understand the precise and clear meaning of an emergency safety-related message.
'ISO 24978 will help make information provided by the vehicle understandable at the point of reception by emergency and rescue services,' says Bob Williams, the leader of the ISO working group that developed the Standard. 'The benefits are significant, particularly for incidents that take place in remote areas or far from the town centre. Statistics show that knowledge of the exact location reduces the response time of the rescue teams by 40% in built-up areas and 50% in rural environments.'
