This invention discloses an interactive method and system for automotive taillights with anti-glare and active warning functions. Addressing the problem that single-dimensional dimming based solely on ambient illuminance is insufficient to simultaneously address glare from following vehicles and glare caused by sudden brightness spikes from brake lights, this invention detects the relative distance, relative azimuth angle, and visibility of the following vehicle to determine the driver's eye position area. Based on the inverse square ratio, cosine incidence, and propagation transmission triple attenuation, the current luminous intensity of the taillight is converted into an estimated eye position illuminance. When the estimated eye position illuminance is not less than a first preset threshold, the luminous intensity is reduced without falling below a second preset threshold. During brake light spikes, the rate of increase in estimated eye position illuminance is limited to a third preset threshold to suppress transient glare. Based on the calculated collision time, a rear-end collision warning is output when it is not greater than a fourth preset threshold. This unified illuminance measurement supports both anti-glare and warning functions, achieving a balance between anti-glare and driving safety without the need for a neural network.
