Animated ambient lighting with intelligent comfort and safety functions

Oct 28, 2020

Thanks to LED technology, the new S-Class has also taken a leap forward in its interior lighting: Mercedes-Benz has now realised interactive interior lighting for the first time. The active ambient lighting (optional) supplements ambient lighting (standard equipment) with an additional layer of light. It is integrated into the driving assistance systems, and is able to reinforce alerts visually. This also makes corresponding feedback possible for the comfort systems. This applies to the climate control system or the 'Hey Mercedes' voice assistant.

The number of LEDs has increased from the previous 40 to around 250 (247 in the W 223, 263 in the V 223). The optical fibres of the active ambient lighting are concealed behind a black panel facing, and are not visible when switched off. An LED is positioned inside every 1.6 centimetres. A strip of light appears when the active ambient lighting is switched on.

The individual LEDs are actuated by CAN-BUS in real time. This allows flowing light effects, a soft transition within the light band and now also colour transitions as well as individual colours. When entering the vehicle, the ambient light band is animated in finely granular form as a welcome feature.

The result is not only a unique appearance by day or night. There are also new, intelligent functions. Integrated into the driving assistance systems, active ambient lighting can visually reinforce warnings. For example, Active Blind Spot Assist warns of an impending collision with a red light animation. Also with the exit warning function of Active Blind Spot Assist, a red visual warning is given in the area of the door where the risk of colliding with traffic approaching from behind, including cyclists, has been identified if exiting the vehicle.

Corresponding feedback is also possible when operating comfort systems. When the temperature is set to cooler or warmer in individual zones, a visible impulse is triggered. When the voice assist "Hey Mercedes" is active, the corresponding seating position is animated when voice input is expected. Furthermore, the ambient lighting and active ambient lighting are integrated into ENERGIZING COMFORT (optional equipment, see relevant chapter). Depending on the mode, the interior is bathed in corresponding colour scenarios.
