What is BMW Adaptive Headlights?
2 Answers
Adaptive high-low beam, also known as automatic high beam, is a feature where the vehicle's headlights use sensors (typically a camera located on the inside of the windshield) to detect oncoming or preceding vehicles and pedestrians at night. The system automatically switches between high and low beams, allowing the driver to focus on driving without the need for frequent manual adjustments. Below are the details: 1. Adaptive High-Low Beam: Under normal circumstances, the vehicle drives with high beams on. However, when it detects the headlights of an oncoming vehicle, taillights of a preceding vehicle, or other light sources, it automatically switches to low beams. It also switches to low beams in well-lit urban areas or when driving at low speeds below 30 km/h, where high beams are unnecessary. 2. Functions of Adaptive Headlights: The adaptive headlight system includes features such as cornering lights, dynamic leveling, and control of the beam angle and range at high speeds. The headlight beams continuously adjust based on the steering wheel angle, vehicle yaw rate, and speed to ensure the light direction aligns with the vehicle's current driving direction. This provides optimal illumination of the road ahead without affecting oncoming or preceding vehicles. The introduction of adaptive headlights has significantly reduced the likelihood of nighttime accidents, enhancing safety for both the driver and other road users.
Last time I drove my friend's BMW on mountain roads, its adaptive headlights really amazed me. This thing is not just ordinary automatic headlights—it can make the light beam turn in advance to illuminate curves based on the steering wheel's angle, so you never have to worry about sudden bends at night. When encountering oncoming traffic, it automatically lowers the beam height to avoid dazzling others, which is especially practical on highways. The light also adjusts its range automatically as the speed increases, and it enhances ground illumination during rainy days. All these functions are achieved through the collaboration of the windshield-mounted camera and front sensors. Although repairs are definitely more expensive than regular headlights, they significantly enhance nighttime driving safety.
