81 LDWS stops vehicles drifting from lanes The Lane Departure Warning System (LDWS ) is a mechanism designed to alert drivers when the vehicle begins to leave its lane (unless the indicator is activated) on highways. These systems are designed to minimize accidents by eliminating the main causes of collision: driver error, distraction, and sleepiness. There are two main types of system: Systems that warn the driver (warning of lane change, LDW) if the vehicle is leaving its lane (visual, audible and / or vibration warnings). Systems that warn the driver and, if no action is taken, automatically take steps to ensure that the vehicle remains in lane (lane keeping support, LKS) The first lane warning system in Europe was developed by US company Iteris for Mercedes Actros trucks. The system was launched in 2000 and is now available in most trucks sold in Europe. In 2002, the Iteris system was made available Freightliner trucks. In both systems, the driver is warned of unintentional lane changes by an audible alert. AEBS prevents collisions The Advanced Emergency Braking System (AEBS) is a safety system designed to reduce the severity of a collision. It is also known as a pre-crash system, direct collision warning system or collision mitigation system. It uses radar (all weather conditions) and sometimes laser (LIDAR) and cameras (using image recognition ) to detect an imminent accident. GPS sensors can detect fixed hazards through a location database. Once detection happens, these systems provide a warning to the driver. These systems act autonomously without any action by drivers (braking or steering, or both). Collision avoidance by braking is appropriate for low vehicle speeds (for example, below 50 kph), while steering collision avoidance is appropriate for higher vehicle speeds. Vehicles can also be equipped with adaptive cruise control and use the same forward-looking sensors. In March 2016 the National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety announced that 99% of US vehicle manufacturers had agreed to include automatic emergency braking systems as a standard feature on virtually every new vehicle sold there by 2022. In Europe, there was an agreement related to the advanced emergency braking system (AEBS) or autonomous emergency braking (AEB) in 2012. The United Nations Economic Commission for Europe (UNECE) announced that such a system would be mandatory for new heavy vehicles as early as 2015. NHTSA forecast that an earlier launch of automatic emergency braking systems would prevent about 28,000 collisions and 12,000 injuries.
