Confidence identification method and system for automatic driving system

Abstract

The present invention provides a method and system for identifying the confidence degree of an automatic driving system, including: determining the hardware used when the current automatic driving system realizes the required functions and the environmental factors that have an impact on the hardware capability of the hardware, and establishing the relationship between the hardware capability and the hardware capability of the hardware The relationship between environmental factors; based on automatic indexing technology and / or data processing and extraction technology to obtain environmental factors on a specific road section in the future in real time, calculate the degree to which the hardware capability of the hardware is affected on a specific road section according to the relationship, and judge in combination with environmental factors The impact of the affected hardware capabilities of the hardware on the automatic driving system to achieve the required functions; and the impact on the function realization will be reflected as the confidence level of the automatic driving system to the driver. According to the present invention, based on the current required functions of the automatic vehicle, the necessary environmental factors in a certain range ahead of the automatic vehicle are pre-identified and processed, so as to prevent the driver from being at a loss in the face of sudden functional failures or failures.

Description

technical field [0001] The invention relates to a method and a system for identifying a confidence degree of an automatic driving system. Background technique [0002] An autonomous vehicle is a vehicle capable of sensing its environment and navigating without human input, and is equipped with an autonomous driving system. An automatic driving system refers to a fully or partially automated, highly centralized operating system that performs tasks performed by human drivers. function, automatic parking function, automatic door opening and closing function, fault automatic recovery function and so on. In addition, the automatic driving system also has multiple operating modes such as normal operation, degraded operation, and operation interruption to achieve system optimization and energy saving. [0003] A certain function of the automatic driving system can perceive the current situation in real time and / or realize the software and hardware capabilities of the function thr...

Problems solved by technology

However, this method can only perceive and respond to software and hardware failures and system failures that have occurred currently, and cannot predict the possibility of future failure of the automatic driving system in advance, nor can it inform the driver in advance of the possibility of future failure of the automatic driving system, resulting in Drivers often panic when faced with sudden functional failures or system failures during driving, which greatly reduces the automatic driving experience
