Vehicle intelligent device for automatically identifying road pit or obstruction

Abstract

A vehicle intelligent device for automatically identifying road pit or obstruction in the technical field of vehicle intelligentialization comprises a binocular pinhole camera, a signal processor, a vehicle speed control mechanism and a voice prompting device; the output interfaces of the binocular pinhole camera are respectively connected with two image input interfaces of the signal processor, and the output interface of the signal processor is connected with the input interface of the vehicle speed control mechanism and the input interface of the voice promoting device in parallel. The binocular pinhole camera transmits the road scene image analog signals respectively collected to the signal processor; the signal processor processes two images in real time, identifies whether pit or obstruction exists in front of the current vehicle, and transmits identification result to the vehicle speed control mechanism and voice promoting device by control command. Once finding out pit or obstruction in the invention, the system can send out control command right now and the vehicle is automatically decelerated, thereby ensuring driving safety; and the incidence rate of road traffic accidents such as vehicle rear-end collision and impact can be obviously reduced.

Description

technical field [0001] The invention relates to a device in the technical field of vehicle intelligence, in particular to a vehicle intelligent device for automatically identifying road pits and obstacles. Background technique [0002] As we all know, deep pits and obstacles on the road often lead to major traffic accidents of fast-moving vehicles, especially on expressways, where any obstacles are absolutely not allowed on the road, otherwise, the consequences will be disastrous. Deep pits or obstacles on the road are often caused by goods dropped by vehicles in front or caused by man-made damage. With the rapid development of traffic and the rapid growth of car ownership, if vehicles do not have the technical function of intelligently identifying deep pits and obstacles, traffic accidents caused by sudden pits or obstacles on the road will inevitably increase significantly . [0003] In order to avoid traffic accidents caused by the above situation, it is necessary to im...

AI Technical Summary

Problems solved by technology

It can be seen that the scope of application of the "obstacle detection device" established by the above-mentioned patent based on the beam characteristics of ultrasonic waves will inevitably be greatly limited: first, the distance of the detected obstacle is extremely limited and can only be used for short distances Measurement; secondly, the beam characteristics of the ultrasonic wave make the coverage of the ultrasonic beam narrow, and it is necessary to configure an area array scanning device to make it possible for the ultrasonic wave to detect obstacles in a larger coverage area

Therefore, the above-mentioned patented technology is obviously not applicable to the detection of obstacles or deep pits ahead of the vehicle
