Abstract

The invention discloses an intelligent driving and ADAS testing method and system based on truth value acquisition. The method comprises the following steps that scene simulation is performed; a test scene truth value, a test vehicle GPS data truth value and a test vehicle pose calculation data truth value are obtained to form an intelligent driving and ADAS test truth value; vehicle sensing driving environment data are acquired and transmitted to the test vehicle decision execution system and the test information fusion evaluation system, and the test vehicle decision execution system controls a test vehicle to execute corresponding decision actions; intelligent driving and ADAS test measurement values are formed through vehicle sensing driving environment data and driving state data; and the test information fusion evaluation system performs preset analysis on perception, decision and execution of the test vehicle according to the intelligent driving and ADAS test true value and the intelligent driving and ADAS test measurement value. According to the method, higher test accuracy and authenticity can be provided, the whole test process can be reproduced completely and truly, and problem backtracking becomes simpler, more convenient and faster.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a test method based on true value collection in intelligent driving tests and ADAS tests. And a test system based on true value collection in intelligent driving test and ADAS test. Background technique [0002] In recent years, the intelligent driving industry is booming, and many giants in traditional industries and the Internet industry have announced their participation in the research and development of intelligent driving. As for the intelligent driving vehicle that has been developed, it needs to be tested in all aspects before it can be commercially mass-produced to ensure the safety of users' personal and property. Putting the test vehicle directly on the actual road test will face various problems such as safety, economy, site reliability, scene diversity, cycle time, etc., while the virtual simulation test can only be used as auxiliary verification, and the test results are...
