Method for carrying out integrated testing on intelligent driving vehicle

Abstract

The invention discloses a method for carrying out integrated testing on an intelligent driving vehicle. The method comprises the following specific steps: (1) realizing a model in-loop simulation testunder a virtual test scene for an intelligent vehicle control strategy and algorithm; (2) realizing a software in-loop simulation test under a virtual test scene for a code generated or handwritten by the model; (3) downloading the model code to the target hardware to realize hardware in-loop simulation test under the virtual test scene; (4) mounting the controller on the intelligent vehicle to realize vehicle in-loop simulation test under the virtual test scene; and (5) mounting the controller on the intelligent vehicle to realize real vehicle test under a real scene, wherein the test scenein the step (1)-(4) is to reuse the same virtual test scene. According to the method, different simulation technologies based on the same test scene are shared in the project development process of asingle ECU of the intelligent vehicle, so that the function and performance of the controller are well verified, and the safety and reliability of the vehicle in the actual driving process are ensured.

Description

technical field [0001] The invention belongs to the field of intelligent vehicle testing, and in particular relates to the design of an integrated testing method for intelligent vehicles. Background technique [0002] As consumers' understanding and demand for vehicle safety continue to improve, the development and application of smart car technology has become an important bargaining chip for the market competitiveness of auto companies, enabling more cars to be equipped with smart systems that can more effectively reduce casualties and improve efficiency , which is more realistic and universal. At this time, in addition to studying the new functions and algorithms of the smart car, ensuring the reliability and safety of the smart car in the driving environment has become the biggest difficulty in its development. Only through perfect smart car testing and evaluation technology can we find problems as early as possible in the research and development stage, dig out hidden ...

AI Technical Summary

Problems solved by technology

[0003] Traditional vehicles are mainly based on actual vehicle testing, which will inevitably bring greater risks

At the same time, relevant national laws and regulations and testing standards have not yet been issued, and there is no practical solution for testing dangerous conditions in specific scenarios

[0004] Some existing ECU simulation tests use different data in different simulation stages, resulting in incomparability of the final test results, so that the function and performance of the controller cannot be well verified, and safety may not be guaranteed in the actual driving process of the vehicle reliability

At the same time, different data are used in the simulation tests of different ECUs of smart cars, which not only increases the cost, but also makes the coordination between different ECUs of smart cars poor, resulting in poor test and evaluation results of smart cars
