KR970015225A - Inter-vehicle distance warning device and method - Google Patents

Abstract

According to the present invention, when the distance between the vehicle in front of the vehicle is lowered below a certain distance while driving the vehicle at a predetermined speed or more, an alarm sound is generated and the display unit indicates that the vehicle is in a dangerous state. A function selection switch 1 for selectively supplying a predetermined voltage to the speed sensor 2 and the infrared sensor 3 to prevent the occurrence of a traffic safety accident such as a collision accident; A speed sensor 2 for electrically detecting a traveling speed of the vehicle; An infrared sensor 3 for detecting a distance from the vehicle in front of the vehicle as an electrical signal; When the traveling speed A and the measured distance B with the front vehicle respectively input from the speed sensor 2 and the infrared sensor 3 are larger than the set speed K and the set distance R, a predetermined control signal is output. A microcomputer 4 for generating; An alarm (5) for generating an alarm sound and generating a drive signal on the display unit (7) when a predetermined output signal is generated in the microcomputer (4); An A / D converter 6 for converting the measurement distance and the dangerous state display data output from the microcomputer 4 into an analog signal and outputting the digital signal to the display unit 7; Distance between the device and the method characterized in that it comprises a display unit 7 for displaying the measured distance and the dangerous state display data output from the A / D converter (6).

Claims (3)

A function selection switch for selectively supplying a predetermined voltage to the speed sensor and the infrared sensor; A speed sensor which electrically detects a traveling speed of the vehicle when the function selection switch is turned "on"; An infrared sensor that detects the distance to the front vehicle as an electrical signal through a signal reflected from the front vehicle when the function selection switch is turned "on"; A microcomputer that generates a predetermined control signal when the traveling speed A and the measured distance B with the front vehicle respectively input from the speed sensor and the infrared sensor are greater than the set speed K and the set distance R; An alarm for generating an alarm sound and generating a drive signal on a display unit when a predetermined output signal is generated in the microcomputer; An A / D converter converting the measurement distance and the dangerous state indication data output from the microcomputer into an analog signal into a digital signal and outputting the digital signal to the display unit; Inter-vehicle distance warning device comprising a display unit for displaying the measured distance and the dangerous state display data output from the A / D converter. Detecting the traveling speed A of the vehicle by turning on the speed sensor when the function selection switch is turned "on"; Detecting whether the traveling speed A detected by the speed sensor is equal to or greater than a set speed K; "Turning on" the infrared sensor when the function selection switch is turned "on"; If the running speed (A) is higher than the set speed (K) or the speed sensor is "on", it detects whether the measured distance (B) with the vehicle ahead is smaller than the set distance (R). And a step of generating a and indicating a dangerous state on the display unit. The method of claim 3, wherein the measuring distance (B) is greater than the set distance (R) comprising the step of displaying the measuring distance to the display unit. ※ Note: The disclosure is based on the initial application.
