Devices, systems, and methods for hardware-based time synchronization for heterogenous sensors are described. An example method includes generating a plurality of input trigger pulses having a nominal pulse-per-second (PPS) rate, generating, based on timing information derived from the plurality of input trigger pulses, a plurality of output trigger pulses, and transmitting the plurality of output trigger pulses to a sensor of a plurality of sensors, wherein a frequency of the plurality of output trigger pulses corresponds to a target operating frequency of the sensor, wherein, in a case that a navigation system coupled to the synchronization unit is functioning correctly, the plurality of input trigger pulses is generated based on a nominal PPS signal from the navigation unit, and wherein, in a case that the navigation system is not functioning correctly, the plurality of input trigger pulses is generated based on a simulated clock source of the synchronization unit.

Hardware-based time synchronization for heterogeneous sensors in autonomous vehicles

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.
