A method of preventing glare and the system for its implementation

摘要

FIELD: transport engineering.;SUBSTANCE: according to proposed method, pulse-modulated light flux is directed on road by means of vehicle headlights. Pulses of light flux reflected from road objects to driver's eyes are gated by light gate arranged in front of driver. Light is modulated by sequence of pulses chosen according to direction of vehicle movement determined by navigation system from ensemble of orthogonal sequences of pulses synchronized by standard time signals. Light flux pulses from headlights of vehicles moving in opposite directions appear nonsimultaneously having fixed time shift relative to each other. System preventing blinding of driver consists of vehicle headlight unit connected with output of headlight control unit, light gate installed in front of drive, control unit whose output is connected with inputs of headlight control unit and light gate. Input of control unit is connected with output of vehicle navigation system.;EFFECT: improved safety on the road owing to prevention of blinding of driver by light of headlights of on-coming vehicles.;3 cl, 3 dwg
