Speed, what is the mandatory ISA standard that respects the limits set by ETSC

From July 6, all newly certified cars in Europe are required to have Intelligent Speed ​​Assist (ISA), a driving assistance system that helps a driver drive within speed limits. No news for cars on the road

Driver assistance systems have made today’s cars safer and now have a significant specific weight gain in maximum scores in tests conducted by Euro Ncap. But according to ETSC – European Transport Safety Council – It is not enough because speed is still the main cause of accidents. According to European estimates, 10-15% of all accidents and 30% of fatal accidents are a direct result of speeding or insufficient speed. To try to nip this factor in its bud, ETSC has for more than a decade backed the viability of Intelligent Speed ​​Assistance (Isa), a driver assistance system that, according to various studies, is an effective life-saving system. By this data on the instrument’s validity, the European Union made the ISA standard mandatory by EU Regulation 2019/2144 The European Parliament and the European Council, which requires, from 6 July 2022, that vehicles in categories M (cars, buses, vans, campers) and N (cargo vehicles of less than 3.5 tons and more) be equipped of homologation New with ISA. As of July 7, 2024, the system should be present in all new vehicles. Certainly nothing will change for the vehicles currently on the road.

How does Isa work?

ISA uses the camera on most new cars to recognize speed signals and data about limits connected to the GPS system, to warn drivers of the current limit and, if necessary, to automatically reduce the vehicle’s speed. ISA systems do not act directly on the brakes, they simply limit engine power by preventing the vehicle from accelerating beyond the current speed limit. The driver can still choose the acceleration by pressing hard on the accelerator pedal. Cars equipped with this type of ISA system are already on sale. Euro Ncap’s decision to allocate additional points to Isa-equipped vehicles has in fact accelerated the device certification process. According to ETSC estimates, ISA is able to reduce collisions by 30% and deaths by 20%.

Positive results

Issa has been tested in several member states, and while it takes drivers some time to get used to the technology, most of them have enjoyed it. One obvious benefit is helping drivers avoid speeding tickets.
