Although you may find the beams stable throughout the video but a closer look would help you to understand the difference when the car passes goes behind a vehicle, climbs above, goes down, or drives through a straight road.
This new feature is unlocked with 2024.2.2 and above OTA software update for the Upgraded Tesla Model 3.
“By detecting other road users and selectively dimming individual pixels of the headlights, the high beams can remain on longer, enabling better visibility at night” describes the changelog.
This feature can be accessed via Lighting > Adaptive High Beams in the vehicle settings zone.
This feature is supported by the Matrix LED headlight, which also comes in Model 3. A matrix LED headlight is an adaptive driving beam (ADB) system with an array of individually addressable and controllable LEDs.
These LEDs work in synchronization with an electronic control unit (ECU) and traffic detection device to optimize light based on the scenario for improved visibility while driving at night time.
When the vehicle detects an object in front of the vehicle, the adaptive lighting system will mask out the oncoming vehicle by dimming or switching off LED engines. It produces destructive glare while other LED engines of the high beam light continue to illuminate everywhere else on the road.
While driving through curves, the high beam LEDs of the matrix headlight will shift the focal point of the light along the curve and illuminate the side of the road more than the road itself.
In the background, the computer vision in the car can extract the road lane information, which can help to improve the precision of adaptive lighting. Furthermore, GPS integration will make it possible to predict headlight control in vehicles.
For now, it’s unconfirmed whether the adaptive high beams feature will be released for old models via an OTA update. Check the video demonstrations below.
