Problems solved by technology

The automatic driving assistance technology itself belongs to the active safety technology, but while it can effectively prevent the occurrence of hazardous events and reduce the degree of harm, it lacks its own effective safety mechanism. The over-belief will greatly prolong the effective takeover time, leading to more serious traffic accidents

Abstract

The present invention relates to a method for analyzing the functional safety concept of an intelligent vehicle VS-LKA system. The method sets relevant operating scenarios of the VS-LKA, determines the failure forms and the resulting hazardous events in different scenarios, and evaluates each hazardous event to determine The automotive safety integrity level of each event, based on this, the functional safety goals for VS‑LKA are formulated and converted into the functional safety requirements and technical safety requirements of VS‑LKA. The analysis of the VS‑LKA vehicle-level functional safety concept stage is conducive to the formulation of corresponding safety control strategies and the design of corresponding fault-tolerant control algorithms in the later stage, so as to effectively ensure the safety of passengers and other traffic participants.

Description

technical field [0001] The present invention relates to a functional safety analysis technology of an intelligent electric vehicle vision system (VS-LKA, Vision System of Lane Keep Assist) applied to lane keeping assistance, in particular to an automatic driving assistance system for intelligent electric vehicles at level L2 or below— VS-LKA's conceptual analysis method for vehicle-level functional safety. Background technique [0002] Whether it is high-level or low-level autonomous driving, it involves environmental perception, autonomous decision-making and real-time control. At present, the perception sensors widely used in the market include laser radar, millimeter wave radar, visual camera, etc. Among them, the visual camera is favored by consumers due to its processing system foundation, intuitive processing effect, low price, and "one head with multiple functions". . Vision cameras can be divided into monocular cameras, multi-eye cameras, fisheye cameras, etc. by t...
