Automatic driving test system and method

Abstract

The invention discloses an automatic driving test system and method. An upper computer generates virtual scene data generates a position correlation radio frequency signal and relative positioning data, a test bench generates first sensing data according to the obtained vehicle control data and virtual scene data. A global satellite navigation system simulator generates absolute positioning data according to the position correlation radio frequency signal, and then a combined navigation module generates second sensing data according to the absolute positioning data and the relative positioning data, so that more comprehensive sensing data required by the automatic driving domain controller for automatic driving control analysis can be obtained; and an automatic driving domain controller performs automatic driving control analysis and generates vehicle control data based on the first sensing data and the second sensing data, so that more real vehicle control data is generated, the vehicle control data has higher reference value, the test result is more objective, and the safety and reliability of the automatic driving test are improved.

Description

technical field [0001] The invention relates to the field of automatic driving, in particular to an automatic driving test system and method. Background technique [0002] Virtual simulation test verification is a very important part of the development process of advanced automatic driving systems. Before the relevant functional modules of the automatic driving system are finalized or put into mass production, a considerable number of functional scene test verifications are required. HIL virtual simulation test technology can effectively identify And discover the defects and problems in the automatic driving system, and accelerate the product development process. [0003] The expected functional safety of autonomous vehicles (SOTIF) refers to the safety risks caused by non-failure, expected functional limitations, and reasonably foreseeable misuse of autonomous vehicles and systems, from the vehicle level, system level, software and hardware Levels and different system comp...

[0004] However, in the existing autonomous driving hardware-in-the-loop simulation test system, a very effective test and verification method has not been proposed for the expected functional safety of the positioning function corresponding to the above-mentioned automatic driving system that relies on the absolute positioning perception technology route. Real-time hardware-in-the-loop simulation testing and verification in positioning function scenarios such as urban canyons, multi-path reflections caused by buildings, traffic facilities, and geographical conditions that lead to decreased positioning accuracy and loss of positioning signals.
