Car, car adas system and control method thereof

Abstract

The invention discloses an automobile, an automobile ADAS system and a control method thereof. Among them, the ADAS system includes a camera and a SOC chip, wherein the camera is used to capture the environment around the car to obtain video data streams, and the SOC chip integrates multiple processors. The method includes: collecting video data streams and CAN control data streams; The video data stream and the CAN control data stream are fused together to generate a fused data stream that includes the video data stream and the CAN control data stream, wherein the fused data stream includes multiple frames of fused images; image processing is performed on each frame of the fused image to obtain Corresponding analysis information and CAN control data; output corresponding image data and / or generate corresponding control signals according to the analysis information and CAN control data. The control method can reduce the data transfer between the processors of the SOC chip, reduce the communication load, and help improve the real-time performance of the ADAS system.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a control method of an automobile ADAS system, an automobile ADAS system and an automobile. Background technique [0002] As the number of cars in our country increases year by year, traffic accidents also increase. In order to protect the life and property safety of car drivers and passengers more effectively, automobile manufacturers are devoting themselves to developing more reliable vehicle-mounted passive safety and active safety assistance systems. Among them, active safety assistance systems are attracting more and more attention. . [0003] In related technologies, the active safety assistance system uses a monocular camera and a SOC chip (System-on-a-Chip, system-on-a-chip) to realize the ADAS (Advanced Driver Assistant Systems, advanced driver assistance system) function of the car, wherein the ADAS function includes Lane departure detection, pedestrian recognition, vehicle...

AI Technical Summary

Problems solved by technology

[0004] Since each processor on the SOC chip obtains image data frames from the video data stream and processes them, and also obtains control data from the CAN control data stream, and the data transfer between the image data frames and control data between the processors is Relying on the "inter-core communication" method of the SOC chip, when the "inter-core communication" is always in a busy state, the real-time performance of the entire system will deteriorate, which will affect the image recognition rate and system reliability.
