Platform one The first ISO safety standard for Level 4 automated driving systems on public roads has been published, focusing initially on low-speed operation (writes Nick Flaherty). The use of low-speed automated driving (LSAD) pods is seen as a way to reduce congestion and carbon emissions around the world, but their roll-out has been hampered by the lack of safety standards. ISO 22737 sets out the specific minimum safety and performance requirements for LSAD systems, providing a common language to help the development and safe deployment of this technology worldwide. The standards group included experts from the USA, Australia, South Korea, China, Germany, France, the Netherlands and the UK. “An increased use of LSAD systems can lead to a shift in the way people, goods and services are transported,” said Dr Siddartha Khastgir, from the University of Warwick in the UK, who led the ISO technical committee that wrote the standard. “This new standard will enable the safe deployment of an environmentally friendly transport option, as well as a solution for people with mobility issues.” The standard includes the minimum operating capabilities for LSAD systems, along with guidance on the operational design domain definition and guidance on how LSAD systems might fit into the wider transport ecosystem. It also specifies the performance requirements for different aspects of the LSAD system, such the dynamic driving task, emergency manoeuvres such as emergency stop and minimal risk manoeuvres, hazardous situation identification, and static and dynamic obstacle detection and avoidance. It also includes the test procedures for various system functionalities to allow manufacturers to demonstrate the Level 4 safety level. “It had become increasingly difficult to communicate the level of safety engineering our vehicles encompass, and difficult to compare various attributes and functionality against the perceived state of the art for this class of vehicle,” said Simon Brewerton, CTO at UK LSAD developer Aurrigo Driverless Technology. “The new LSAD standard draws a line in the sand for all OEMs to exceed, and so enables a global market where all players rise to the same standards.” Standard set for Level 4 Driverless cars YOUR PROPULSION SYSTEM PARTNER FULL ENGINE INTEGRATION FOR THE FUTURE Rotron rotary engines reflect an entirely different approach to fully-integrated propulsion systems, by redefining the relationship between size, performance, efficiency and reliability in an ultra-low vibration power unit.
