Vision-based active safety system with car audio and video entertainment function

Abstract

The invention provides a vision-based active safety system with a car audio and video entertainment function. A main processor, a Camera video decoding chip, a Flash memory, a power management chip and the like are arranged in a machine shell; a display touch screen and a key panel are arranged on the machine shell; the key panel is provided with an AUX (auxiliary) inputting opening and various functional keys; an inputting end of the main processor is connected with the power management chip, the Camera video coding chip, an Audio Dsp (digital signal processor) and a power amplifier chip; the Camera video decoding chip is connected to four cameras distributed on the periphery of a car body; and the cameras are used for 360-degree round-looking, lane changing warning, park assisting and driving recording. By the vision-based active safety system with the car audio and video entertainment function, a car audio and video entertainment system and an ADAS (advanced driver assistance system) are integrated, and the costs of structures, circuit boards and software can be greatly reduced; and functions are switched over by keys of the touch screen or hard keys, active safety can be implemented on a car safely and conveniently, and the vision-based active safety system shows a direction for future development of the ADAS.

Description

technical field [0001] The invention relates to a vehicle-mounted audio-visual entertainment system, in particular to an active safety system integrating vehicle-mounted audio-visual entertainment functions. Background technique [0002] Since vision-based ADAS (Advanced Driver Assistance Function) has the characteristics of low cost, high accuracy, and visualization, vision-based ADAS is more and more widely used in the field of automotive safety, and has become one of the indispensable electronic devices in automotive safety systems. one. At present, the existing vision-based ADAS products on the market mainly have the following two characteristics: 1. It is an independent electronic device. If it is to be installed in a car, it needs to occupy additional space in the center console and occupy an independent wiring harness interface and bus resources. 2. The functions are simplistic, only for a specific application (such as only cruise control, or only 360o surround view...

Problems solved by technology

At present, the existing vision-based ADAS products on the market mainly have the following two characteristics: 1. It is an independent electronic device. If it is to be installed in a car, it needs to occupy additional space in the center console and occupy an independent wiring harness interface and bus resource

2. The functions are simplistic, only for a specific application (such as only cruise control, or only 360o surround view, or only lane change warning, etc.), and there is no integration of multiple image recognition technologies in the same system

[0003] In short, independent ADAS not only has a single function, but also takes up additional space in the center console, which increases the number of ECU nodes, bus load and user operation complexity, which is not conducive to vehicle loading, and the concept of high-density integration with today's vehicle electronic equipment out of place
