Driverless vehicle control system and method based on full-audio perception

Abstract

The invention relates to the technical field of intelligent driving, and discloses a driverless vehicle control system and method based on full-audio perception. The system comprises a machine visionsubsystem and a full-audio perception subsystem, wherein the machine vision subsystem and the full-audio perception subsystem are separately connected with a central data processing and control unit of the driverless vehicle; the full-audio perception subsystem transmits full-audio perception information and vehicle control decision information to the central data processing and control unit through all-audio data fusion and a decision maker, and meanwhile receives returned vehicle control information transmitted by the central data processing and control unit; and the central data processingand control unit compares perception information of the various subsystems, and judges the accuracy of the perception information of the all-audio perception subsystem. Vehicle location, road perception and driving logic judgment can be realized, and the shortcoming that a conventional vehicle intelligent driving perception system cannot understand driving intentions of other vehicles and cannot recognize blind spots shielded by barriers is overcome.

Description

technical field [0001] The present invention relates to the technical field of unmanned driving, and more specifically, relates to an unmanned vehicle control system and control method based on full audio perception. Background technique [0002] The perception system of the traditional unmanned driving system mainly relies on millimeter-wave radar, lidar system, camera and other devices, which can be considered as a vision system. information to form various automatic or autonomous control methods. [0003] For example, the invention patent application with publication number CN106527427A discloses a highway-based automatic driving perception system, and the vehicle driving environment adopts a complete vision system. Based on this method, although the space-vehicle coupling relationship is established, for real simulated human driving, only visual information does not constitute all driving logic relationships, and auditory information is also an important basis for logic...

AI Technical Summary

Problems solved by technology

The existing technology only has spatial position information but no sound information. The unmanned driving system is similar to a human being who only has vision but no hearing. It is almost "deaf". The changing trend of the environment, the safety of its activities must be limited

And in some visual blind spots, it is impossible to get all the environmental information
