Current consensus
Intelligent speed assistance is a driver assistance system uses a speed sign-recognition video camera and-or GPS-linked speed limit data to advise drivers of the current speed limit and automatically limit the speed of the vehicle as needed.
Explanation
ISA systems do not automatically apply the brakes, but simply limit engine power preventing the vehicle from accelerating past the current speed limit unless overridden. Vehicles with this kind of ISA system factory fitted are already on sale – helped in part by Euro NCAP’s decision to reward extra points for vehicles that include ISA.
- Number
- Systems can use satellite-based tracking of vehicle position against a database of speed limits and-or cameras to detect speed limits shown on road signs (including electronic signs and signals). Speed limits may also be broadcast from infrastructure to vehicles to communicate relevant speed limits to the ISA system. Some systems provide a human driver with warnings of excessive speed while others actively moderate vehicle speed to comply with limits.
- This term was referred to as intelligent speed adaptation in previous versions of this vocabulary.
