Intelligent tail lamps - requirements and benefit of adaptive signal lights Adaptive Rear Lighting Systems (ARS)

摘要

The backward light signals of motor vehicles are submitting relevant information about the driver's behavior to the following traffic. The perceptibility of the discrete light functions of rear lamps is variably influenced by different environmental impact. To define the ideal perceptibility of signal lights the luminous intensities have to be considered in conjunction with the adaptation luminance and bearings like the superposition of sunlight as well as driving conditions. According to actual ECE regulations, rear direction indicators as well as stop, tail and fog lamps can be designed with variable luminance levels dependent on ambient light. This regulation permits a luminance intensity range for each signal and prescribes variable transitions, but lacks on specifications about the interconnection of the signal lights and the influencing parameter.
