Blindvinkelvarning

Blindvinkelvarning, often abbreviated as BSW or BLIS (Blind Spot Information System), is a safety feature designed to alert drivers to the presence of vehicles in their blind spots. This system typically uses sensors, such as radar or ultrasonic, mounted on the rear corners of the vehicle. These sensors continuously monitor the areas to the sides and rear of the car that are not visible in the driver's mirrors.

When a vehicle enters a blind spot and is detected by the sensors, the BSW system activates a visual warning, usually a light or icon, in the corresponding side mirror or on the dashboard. If the driver then activates the turn signal in the direction of the detected vehicle, an audible warning is typically added to the visual alert, emphasizing the potential danger of a lane change.

The primary purpose of blindvinkelvarning is to reduce the risk of collisions that can occur when drivers are unaware of other vehicles in their blind spots, particularly during lane changes or merging maneuvers. The effectiveness of BSW systems can vary depending on factors such as the type of sensors used, the vehicle's speed, and the environmental conditions. It is important for drivers to understand that while BSW is a valuable aid, it does not replace the need for drivers to actively check their mirrors and look over their shoulders before making any changes in direction.
