Whole-vehicle in-loop test bench system of L3-level automobile driving automobile

Abstract

The invention provides a whole-vehicle in-loop test bench system of an L3-level automobile driving automobile. The system comprises a chassis dynamometer located at the central position of an annularscreen, wherein a first vehicle is placed on the chassis dynamometer, the first vehicle comprises a first vehicle body and a first vehicle controller, at least one vehicle-mounted camera is installedon the first vehicle body, an image data signal output end of each vehicle-mounted camera is connected with an image data signal input end of the first vehicle controller, and the vehicle-mounted cameras are used for acquiring continuous test scenes displayed on the annular screen. Through the system, changing of the lane line sate in the testing process can be realized; and through real-time synchronous changing of a moving target (e.g., another vehicle, a bicycle and a pedestrian), lane lines and surroundings, whole-vehicle continuous in-loop testing of the L3-level automobile driving automobile is realized.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a vehicle-level in-the-loop test bench system for L3 automatic driving vehicles. Background technique [0002] With the rapid development of autonomous driving technology, more and more autonomous vehicles (L1 / L2) with ADAS functions have been put into mass production, and even many auto companies have begun to plan the marketization process of L3 autonomous vehicles. It is expected that in 2020, mass-produced vehicles with L3 autonomous driving functions will enter the market. For the testing of autonomous vehicles, it is predicted that an average of 1.3 million miles of test mileage is required to ensure the safety of the system. Therefore, traditional field testing and road testing can no longer meet the testing requirements of autonomous vehicles. In view of the above difficulties, using in-the-loop testing to conduct tests in the development and verification stage...

AI Technical Summary

Problems solved by technology

[0010] In the existing vehicle-in-the-loop system scheme, since the state of the physical lane lines around the test vehicle cannot be changed, it is impossible to test the relevant functions of the test vehicle based on lane line recognition. Therefore, the existing related schemes can only Meet the partial test requirements of L1-L2 ADAS autonomous vehicles, but cannot meet the vehicle-level test requirements of L3 autonomous vehicles
