Description

Technical Field

[0001] The present invention relates to the technical field of intelligent network-connected vehicle testing, and in particular to a performance testing device for an intelligent network-connected vehicle. Background Art

[0002] Testing of intelligent connected vehicles is a key link to ensure their safety, reliability and functionality. With the development of technologies such as artificial intelligence and big data, the testing technology of intelligent connected vehicles will become more and more intelligent and automated. It usually includes network security testing and functional safety testing. Functional safety testing includes hardware reliability testing and software functional safety testing.

[0003] Hardware reliability testing is a reliability test of the key hardware components of the vehicle (such as sensors, controllers, actuators, etc.). Through accelerated life tests and environmental adaptability tests (such as high temperature, low temperature, humidity, vibration, etc.), the failure probability and service life of hardware components under different working conditions are evaluated. Software functional safety testing is used to check the functional safety of vehicle software systems (including autonomous driving software and Internet of Vehicles software). Testing methods such as fault injection and boundary value analysis are used to verify whether the software can enter a safe state under abnormal conditions (such as data errors, sensor failures, etc.) to avoid vehicle loss of control or other safety accidents due to software failures. For example, when the vehicle's speed sensor fails, the software should be able to detect it in time and take reasonable measures (such as limiting the speed or prompting the driver to take over the vehicle).

[0004] In order to improve the efficiency of the test, the car is usually placed on a test device, and the test device is used to simulate different working conditions to test the vehicle. However, the existing test devices simply connect the vehicle's driving speed. However, when the vehicle is driving, the body posture will change, so it needs to be improved.
