This article describes various in-vehicle driver assistance systems. In adaptive cruise control, sensors continuously observe the vehicle's surroundings and can adjust the following distance. New versions will be able to brake a vehicle from high speed to standstill and warn of possible rear-end collisions. Blind spot detection makes overtaking and lane changing safer. Lane change assist can observe vehicles approaching from up to 80m behind. Lane departure warning protects the driver from inadvertently changinglanes, reducing the danger from inattention or microsleep. Intelligent headlamp control enables better night vision as it sets the lamps to provideoptimum lighting without dazzling oncoming drivers. Traffic sign recognition displays the current speed limit to the driver. Collision mitigation systems can reduce stopping distance. A closing-velocity sensor as part of a predictive emergency braking assistant activates automatic braking if there is a risk of collision. Trailer stabilisation can also be part of braking systems, with the possible addition of roll-over protection.
