Intelligent speed adaptation
Intelligent speed adaptation (commonly known as ISA) continuously monitors the speed limits during driving and if the car’s speed exceeds the speed limit takes action so that it slows down. This can be achieved by simply warning the driver through several methods (including audio) or through an active system which automatically controls the driving systems of the vehicle, making it reduce its speed. The ISA system uses various information about the zone through which the vehicle is going and takes some decisions about what the maximum speed should be. The system knows when the car has entered a new speed zone. It even knows when variable speed zones are in force (for example school zones). ISA can work with temporary speed zones like accident scenes or other special conditions. The Intelligent speed adaptation device is made to help the drivers be on the safe side of the law regarding speed. The system greatly helps the driver when driving through unknown zones or in zones with variable speed limitations.
