System and method for testing driving performance of autonomous vehicle in punctured tire condition

Abstract

The invention relates to a system and method for testing driving performance of an autonomous vehicle in punctured tire condition. The system comprises a test field, a punctured tire simulating device, an in-vehicle sensor, an off-board monitoring device, a data acquisition device and a background PC, wherein the test field is provided with a test road, the punctured tire simulating device is arranged at a set position in the test road, the in-vehicle sensor is arranged in a vehicle and records state parameters during a driving process of the vehicle, the off-board monitoring device is set inthe test field and records the position and posture of the vehicle, the in-vehicle sensor and the off-board monitoring device are connected to the background PC through the data acquisition device. Compared with the prior art, the system and method for testing driving performance of an autonomous vehicle in punctured tire condition can effectively and reliably complete the test and verification ofdriving performance of the autonomous vehicle in punctured tire condition, fill the gap in the field of dangerous working conditions test for autonomous vehicles, and provide a reference for the study of access standards for autonomous vehicles.

Description

technical field [0001] The invention relates to the technical field of self-driving vehicle testing, in particular to a driving performance testing system and a testing method of a self-driving vehicle under tire blowout conditions. Background technique [0002] Tire blowout at high speed is an extremely dangerous situation. For manned vehicles, since the vast majority of drivers do not have experience in dealing with tire blowout accidents, during the occurrence and development of a tire blowout, the driver is affected by the external environment and The influence of factors such as one's own psychology can easily lead to the occurrence of vicious traffic accidents. [0003] Self-driving vehicles cannot avoid the problem of flat tires during driving. Although autonomous driving systems rely on reliable sensors and efficient actuators, they can ideally have better vehicle control capabilities than human drivers. However, as the level of automatic driving continues to incre...

AI Technical Summary

Problems solved by technology

However, as the level of automatic driving continues to increase, the role of the human driver will continue to be weakened. Once a vehicle blows out, it will be difficult for the human driver to intervene in the vehicle control in time. At this time, we can only hope that the automatic driving system itself has excellent performance. The ability to independently handle tire blowout accidents
