Abstract: The present disclosure relates to autonomous vehicle technology, and provides a method and an apparatus for trailer angle measurement, as well as a vehicle. With the present disclosure, it can be determined whether to use a single-beam lidar or a multiple-beam lidar for trailer angle measurement based on an initial trailer angle. When it is determined to use the multiple-beam lidar a deflection direction of the semi-trailer can be obtained, and laser light emitted by the multiple-beam lidar on a side of the deflection direction and reflected by a trailer surface can be collected. A coordinate transformation and selection process can be applied on the laser point cloud to form a candidate point cloud. A boundary straight line of the trailer can be determined by means of optimized solution of the candidate point cloud. A trailer angle can be determined based on the boundary straight line of the trailer.

Abstract: A method includes: receiving information about a fault type of a sensor; generating an instruction corresponding to the fault type of the target sensor, the instruction including a fault parameter, and the fault parameter including an injection mode of the fault type and a fault occurrence probability; and obtaining target sensor data having the fault type based on the injection mode of the fault type and the fault occurrence probability. In some embodiments, an injection mechanism of the fault types of the target sensors is increased, and the target sensor data corresponding to different scenes are rendered on the basis of the fault types, thus reducing occupation of real test resources.

Abstract: The present disclosure relates to intelligent driving technology, and provides a method, device, and system for simulation test. The method includes: retrieving data in a first format for a first sensor from a database; processing the data in the first format to obtain corresponding data in a second format, the second format being a format of data collection of the first sensor; and transmitting the data in the second format to a second computing device capable of performing a simulation test based on the data in the second format. The present disclosure can provide a simulation test solution for an intelligent system by providing a simulation test environment closer to the real-world environment.
