Collision avoidance refers to the techniques and systems designed to prevent accidents between moving objects, such as vehicles, aircraft, or ships. These systems use sensors, cameras, and radar to detect potential obstacles and calculate the best course of action to avoid a collision. In the context of automobiles, collision avoidance technology includes features like automatic emergency braking, lane departure warnings, and adaptive cruise control. These advancements enhance safety by alerting drivers to potential dangers and, in some cases, taking control of the vehicle to prevent accidents.
