[0002] With the development of autonomous driving technology, the functions of vehicle-mounted sensors are becoming more and more powerful. Common sensors include cameras and lidars. Cameras are used to obtain image information of objects around the vehicle, and lidars are used to obtain point cloud information of objects around the vehicle. By fusing information from various sensing devices, autonomous vehicles can perceive the surrounding environment more accurately to ensure safe driving of autonomous vehicles.

[0003] In the existing technology, most of the troubleshooting of autonomous driving sensors needs to be tested in a real vehicle environment, that is, the problem is reproduced by the vehicle for analysis. Such reproduction is not only time-consuming and labor-intensive, but also wastes vehicle testing resources to a great extent. For phenomena with low occasional probability, it leads to technical problems such as difficulty in testing and reproducing problem scenarios on a real vehicle, low testing efficiency and high testing costs. Relying solely on the autonomous driving controller for recording is likely to occupy a large memory space, affecting the operation of the controller, and it is impossible to record more detailed basic parameters such as the operating current and voltage of the sensor.
