Prompting system of vehicle rear tail anti-collision and method of vehicle rear tail anti-collision

Abstract

The invention discloses a prompting system of a vehicle rear tail anti-collision and a method of the automobile rear tail anti-collision. The prompting system of the vehicle rear tail anti-collision comprises a detection assembly and a prompting assembly, wherein the detection assembly is arranged at least one detector designated position at the tail part of a self-vehicle, the detection assemblycomprises at least two detectors of at least one detector type, the detectors are provided with detection areas which are not overlapped with each other, and each detector is used for periodically detecting whether a rear-vehicle exists in each preset detection period in the detection area corresponding to the each detector. According to the prompting system of the automobile rear tail anti-collision and the method of the automobile rear tail anti-collision, the core problem of preventing other vehicles at the tail part of the self-vehicle from colliding the rear-end of the self-vehicle can beeffectively solved, by arranging a necessary detection system, the detection time and the judgment logic of the detection system can be enhanced at the same time, so that the prompting system of thevehicle rear tail anti-collision can be matched with a mainstream vehicle type while having the characteristics of portability, integration and the like, so that the vehicle can be conveniently subjected to nondestructive modification, and has the good rear-end prevention ability.

Description

technical field [0001] The invention belongs to the technical field of vehicle early warning, and in particular relates to an automobile rear-end anti-collision prompting system and an automobile rear-end anti-collision prompting method. Background technique [0002] The publication number is CN102785660A, and the subject name is vehicle anti-collision warning device. Steering sensor, single-chip microcomputer and early warning device; among them, the image acquisition module collects the information in front of the vehicle and sends it to the image processing module, and the image processing module sends it to the single-chip microcomputer after processing. The relative distance and relative speed data are sent to the single-chip microcomputer, and the ultrasonic sensor sends the measured vehicle speed to the single-chip microcomputer. After the single-chip computer processes the image information and distance and speed data, it judges whether the vehicle is in a critical s...

Problems solved by technology

[0003] However, taking the above-mentioned invention patent as an example, in order to achieve the two purposes of anti-collision and early warning, the existing anti-collision system for automobiles needs to build a relatively complex detection system and early warning system, such as millimeter-wave radar and ultrasonic radar for speed measurement. , speed sensor, etc., which obviously greatly increase the design complexity and material cost of the whole machine, which is not conducive to the mainstream development trend of portability, miniaturization and integration, and cannot be easily non-destructively modified on existing vehicles
