A method for dynamically displaying a fault warning light signal behind a car

Abstract

The invention provides a method for dynamically displaying fault warning light signals at the back of an automobile and belongs to the field of signal display devices. A fault warning mark lamp with a long-shoot function is adopted, and red light beams are emitted backwards from the tail part of the automobile to form a group of dynamic light spots or a light band formed by multiple mobile light spots on the ground behind the automobile or below the view of a driver driving in the same direction behind the automobile, so that a dynamic and striking special situation warning mark light shape is formed by irradiation or mapping. Due to the fact that the fault warning mark light shape is formed at the tail part of the automobile with faults, the dangerous process that the driver is required to place a fault warning mark after the automobile is stopped due to the faults is omitted, the personal safety of the driver who places the fault warning mark is guaranteed favorably, an obvious fault warning signal can be quickly provided for other vehicles running in the same direction behind the automobile which is stopped due to the faults on the road, the vehicles behind are reminded of keeping a safe driving distance, rear-end accidents are avoided, and the method can be widely used in design and manufacture fields of signal lamp devices of automobiles.

Description

Technical field [0001] The invention belongs to the field of signal display devices, and particularly relates to a method for displaying a fault warning light signal at the rear of a car. Background technique [0002] Adopted at the 31st meeting of the Standing Committee of the Tenth National People’s Congress of the People’s Republic of China on December 29, 2007, the 50th "Road Traffic Safety Law of the People’s Republic of China" came into force on May 1, 2008 Article 2 stipulates: When a motor vehicle breaks down on the road and needs to be stopped for troubleshooting, the driver shall immediately turn on the hazard warning flasher and move the motor vehicle to a place that does not hinder traffic; if it is difficult to move, the hazard warning flasher shall be continuously turned on , And set warning signs in the direction of the vehicle to increase the warning distance; Article 68 stipulates that when a motor vehicle breaks down on an expressway, it shall be handled in acco...

Problems solved by technology

However, in the actual driving process, it is usually difficult for the driver of the following vehicle to accurately distinguish the vehicle that issued the "double flashing" light signal from a long distance (referring to a distance greater than the relevant regulations) when driving at high speed. The use of "double flashing" signal lights for any reason is difficult to ensure the safety of vehicles parked in trouble or vehicles that need to send special warning light signals backwards and subsequent vehicles driving in the same direction, which often easily leads to vehicle rear-end collision accidents
