The invention provides a trailer included angle measuring method and device and a vehicle, and relates to the technical field of vehicles. The method is applied to a semitrailer comprising a tractor and a trailer. At least one multi-line laser radar is arranged on each of the two sides of the tractor; the method comprises the following steps: under a preset vehicle coordinate system, obtaining a trailer initial model when a trailer included angle is an initial value, and obtaining initial point cloud data on the trailer initial model; multi-line laser radars arranged on the two sides of the tractor are controlled to emit laser, so that the surface of the trailer reflects the laser emitted by the multi-line laser radars; controlling each multi-line laser radar to receive the corresponding laser point cloud reflected by the surface of the trailer; and according to the corresponding laser point cloud and initial point cloud data received by each multi-line laser radar, a trailer included angle is calculated by adopting a point cloud matching algorithm. The method is simple in structure and capable of rapidly and accurately measuring the included angle of the trailer.
