Automatic tracing system and method of intelligent driving test

Abstract

The invention discloses an automatic tracing system and method of intelligent driving test. The system comprises a differential GPS base station, a server, a beyond-the-horizon data transmission radiostation, a main controller, a power distribution system, an inertial navigation system and an auxiliary system; the server is connected with the differential GPS base station and the beyond-the-horizon data transmission radio station; the differential GPS base station is used to locate a positional diameter of an intelligent driving dolly to realize the millimeter level positioning precision. Anelectric motor car with a high precision navigation system is controlled to drive accurately along a predetermined route in the specific route and speed, whether a control behavior of the automatic driving vehicles accords with expectation can be tested accurately and repeatedly, the system can be combined with a test chassis to solve the problem that computer simulation cannot realize practical road condition test, a test result approaches the reliability more and is more reliable, the complex domestic road condition including too many people and narrow roads is taken into consideration, dummy people and vehicles are supported, and a test scene is more comprehensive and accurate.

Description

technical field [0001] The invention relates to automatic driving, in particular to an automatic tracking system and method for intelligent driving test. Background technique [0002] Autonomous driving technology has become a hot topic at present, and major car manufacturers are intensively developing buses, logistics vehicles, and cars with various automatic driving functions. In the development process of these vehicles, whether it is possible to construct a test system that can prevent accidental collisions, be automated, repeatable, and have a high degree of coincidence with the real scene has become the key to determining the development speed and functional reliability. Among the existing solutions, the Computer simulation is the main method. It mainly collects on-site traffic scene data to obtain vehicle driving scene parameters, then fits the distribution of key parameters to generate specific test events, and evaluates whether the automatic driving behavior conform...

AI Technical Summary

Problems solved by technology

[0003] There are several problems in the current technical solution: the software can only do early theoretical analysis or troubleshooting, the real road scenes vary widely, it is difficult to abstract and extract relatively complex real scenes, and the evaluation and reliable analysis of actual functions still depend on the actual situation. road test

[0004] The test plan of the foreign ABD company is expensive, and it is not acceptable to domestic car manufacturers, and its test environment is mainly aimed at the scene of driving on the expressway in foreign countries, and it is mainly a fake car. It does not consider the narrow domestic road conditions, partial occlusion, The scene where people and vehicles are mixed, this kind of scene needs to simulate the behavior of both cars and people
