Intelligent auxiliary control method applied to passenger vehicle blind area

Abstract

The invention relates to an intelligent auxiliary control method applied to the blind area of ​​a passenger car, a display screen, a blind area camera module, a video switching logic controller, and an application processor implemented by means of split screens respectively installed on the automobile; comprising the following steps: 1. First, install the surround view camera module on the car, and then adjust the angle of view of each camera in the blind area camera module according to the car model and the surround view blind area of ​​the surround view camera module, so that the blind area formed by the angle of view of each camera is covered by the surround view blind area ; Step 2, at first, according to the vehicle action signal first through the trigger signal interface input signal to the video switching logic controller, the video switching logic controller then sets the control scheme of each camera in the blind spot camera module in the driving of the car according to the signal; Then, the application processor plays the camera content displayed by the control scheme on a single screen or in split screens in real time on the display screen; the invention has reasonable design, compact structure and convenient use.

Description

technical field [0001] The invention relates to an intelligent auxiliary control method applied to blind spots of passenger cars, and is particularly suitable for cars with less than 9 seats. Background technique [0002] With the increasing popularity of family cars in China, cars have become people's means of transportation. However, due to the blind spots of moving forward, turning and reversing in cars, the existing technology solves the problem through radar, or only by installing a camera on the rearview mirror. Realize all-round three-dimensional monitoring of the surrounding situation. Although the 360° surround view system such as patent 201611059915.5 is also used in high-end family cars, its viewing angle range is small and real-time dynamic monitoring cannot be realized. Although the prior patent ZL201610222471.6 discloses a vehicle-mounted system , but its structure is simple, unable to meet the needs of moving forward, turning, and real-time dynamic display. C...

Problems solved by technology

It cannot be displayed on the screen in real time, it needs to be triggered, and BSD cannot work in real time

CN201020112040.2 A blind-spot-free driving visualization system requires infrared sensors to cooperate with displaying corresponding images, and cannot realize surround viewing and three-dimensional monitoring. It concentrates processing operations on the processor, thereby increasing the workload of the processor, thereby There is a reaction delay (about 3-5 seconds), and the reaction speed is slow. When the car is driving, the road conditions change rapidly. When the driver relies on the display screen, the reaction time is delayed here, and the correct emergency judgment cannot be made, resulting in traffic accidents

In addition, automobile manufacturers all adopt customized processes and production lines. This system is customized. For example, patent 201611059915.5 requires communication with automobile manufacturers and pre-installation, but it is not realistic in actual social life, which affects the appearance of the car. It is necessary to redesign the appearance of the car, the obstacle of the acceptance standard of the factory standard of the car, it is not beautiful, and cannot meet the individual requirements, and the driving habits of each driver are different
