Abstract

The invention discloses a cooperative self-adaptive cruise control fault-tolerant design system based on expected function safety, and aims at cooperative self-adaptive cruise control of an intelligent network connection automobile technology to carry out fault-tolerant design based on the expected function safety. The system includes two parts of: hazard analysis and evaluation based on expected function safety, function improvement and test evaluation and performance defect fault-tolerant control based on the expected function safety. wherein the performance defect fault-tolerant control based on expected function safety comprises an information acquisition layer, an upper-layer controller fusing performance defect tolerance, decision logic, a CACC fault-tolerant lower-layer controller and a car following execution layer. The invention aims to provide a cooperative self-adaptive cruise control fault-tolerant design architecture based on expected function safety, which is used for solving the problem of vehicle damage caused by insufficient design and functional defects of the existing cooperative self-adaptive cruise control function, and ensuring the driving safety in a cooperative self-adaptive cruise control function mode.

Description

technical field [0001] The invention relates to the technical field of intelligent networked vehicle safety, in particular to a cooperative adaptive cruise control fault-tolerant design system based on expected functional safety. Background technique [0002] Automobiles have brought great convenience to human travel, but at the same time, they have also brought many problems such as traffic accidents, road congestion, energy shortages and environmental pollution. In recent years, intelligent networked vehicles equipped with intelligent and information-based software and hardware have provided new solutions to the above problems. Among the various emerging intelligent connected vehicle technologies, cooperative adaptive cruise control is the one that is closest to the final form. The practical application of this function is conducive to reducing the inter-vehicle distance when driving, improving road traffic efficiency, reducing energy consumption, and bringing huge social...
