SPEED-SENSITIVE COLOR CHANGEABLE CLUSTER SYSTEM AND A CONTROL METHOD THEREOF OF A VEHICLE FOR PREVENTING OVERSPEED BY VISUALLY WARNING A DRIVER WITH CHANGING COLORS OF AN ILLUMINATOR AND A POINTER OF A SPEEDOMETER

摘要

PURPOSE: A speed-sensitive color changeable cluster system and a control method thereof of a vehicle are provided to secure safe driving and to upgrade quality of the vehicle by displaying visually vehicle speed through color-change of a back panel and a pointer of a cluster. CONSTITUTION: A speed-sensitive color changeable cluster system for a vehicle is composed of a speed sensing unit(10) for detecting traveling speed of the vehicle and delivering an analog signal; a signal processing unit(12) for outputting the analog signal sent from the speed sensing unit into a PWM(Pulse Width Modulation) digital signal; a cluster(13) having multicolored LED(Light Emitting Diode) for changing the color by receiving variable resistance value of the signal processing unit; and a siren(14) for generating an alarm sound through a speaker if the traveling speed of the vehicle is over a constant value.
