Problems solved by technology

However, the existing intelligent driving vehicle-in-the-loop testing technology only involves the simulation of the surrounding environment of the vehicle, the vehicle under test and the driving parameters of the vehicle under test, the simulation of the surrounding environment of the vehicle, the driving parameters of the vehicle under test, and real-time road information There is no real connection between the three, and the real-time matching between the intelligent driving vehicle test scene and the intelligent driving vehicle operating road environment cannot be realized, and the full-scenario dynamic real-time closed-loop test of the vehicle-in-the-loop cannot be realized, resulting in low accuracy of test results

Embodiment 1

[0018] figure 1 It is a flowchart of an in-the-loop test method for an intelligent driving vehicle provided by the first embodiment of the present invention. This embodiment is applicable to the situation of an in-the-loop test of an intelligent driving vehicle, and the method can be executed by an in-loop test system.

[0019] First of all, it needs to be explained that the intelligent driving vehicle refers to the vehicle that adopts the unmanned driving scheme. The unmanned driving scheme is based on the real vehicle and is realized by means of high-precision maps, radar and positioning technology, in order to expect complete control by the computer When the car is driving, it is completely liberated that people have been driving in the vehicle.

[0020] In order to ensure the good performance of the vehicle in different environments and the safety of driving, a series of test experiments are required before the vehicle is finalized to test the performance of the vehicle's intell...

Embodiment 2

[0044] figure 2 It is a flowchart of a smart driving vehicle-in-the-loop test method provided in the first embodiment of the present invention. On the basis of the foregoing embodiment, the embodiment of the present invention further optimizes the smart driving vehicle-in-the-loop test method, such as figure 2 As shown, the optimized in-loop test method mainly includes the following steps:

[0045] S210. The test scenario information is adjusted in real time by the test server according to the received vehicle state information; wherein, the vehicle state information is collected in real time by the dynamometer module and sent to the test server.

[0046] In this embodiment, real-time adjustment of the test scenario information can be understood as the test scenario changes over time, for example: from scenario 1 to scenario 2, it can be one of any test scenario information, and scenario 2 can also be any One of the test scene information.

[0047] It should be noted that changes i...

Abstract

The embodiment of the invention discloses an intelligent driving vehicle in-loop test method and a test system. The method includes the following steps that: a test server adjusts test scenario information in real time according to the received vehicle state information; the vehicle state information is collected by a dynamometer module in real time and sent to the test server; the dynamometer module generates a simulated road environment corresponding to the adjusted test scenario information, so that a tested vehicle runs in the simulated road environment according to the adjusted test scenario information; and the test server determines the performance of the tested vehicle according to the vehicle running parameters, wherein the vehicle running parameters are determined by each piece of vehicle state information and the test scenario information within the test period. According to the technical scheme provided by the embodiment of the invention, the test scenario information, thestate information of the tested vehicle and the simulated road environment can be correlated in real time, the in-loop full-scenario dynamic real-time closed-loop test of the vehicle can be realized,the in-loop test scenario is consistent with an actual road environment, and thus the test accuracy is improved.

Description

Technical field [0001] The embodiment of the present invention relates to the technical field of vehicle testing, in particular to an in-loop testing method and a testing system for an intelligent driving vehicle. Background technique [0002] With the rapid development of vehicle intelligent driving technology, the software and hardware capabilities, data fusion capabilities, and core computing capabilities of the intelligent perception module, intelligent decision module, execution module in the vehicle are continuously updated and iterated, and the intelligent driving vehicle-in-the-loop test has become intelligent driving. A key link in the vehicle development process. [0003] At present, real-vehicle-in-the-loop testing needs to input the surrounding environment data into the above-mentioned vehicle under test in the form of simulation, and control the vehicle under test to run on the actual road to realize the performance test of the vehicle under test. However, the existin...
