Abstract

The invention discloses an angle measuring device and a semi-trailer transport vehicle. The angle measuring device is arranged on the semi-trailer transport vehicle. The semi-trailer type transport vehicle comprises a tractor and a semi-trailer, and the semi-trailer is rotationally connected with the tractor through a traction pin. The traction pin and the semitrailer are static relatively, and the traction pin and the tractor rotate relatively. The angle measuring device comprises a guide wheel and an angle sensor, the guide wheel is arranged on the tractor, the outer wall of the guide wheel is in contact with the outer wall of the traction pin, and the traction pin drives the guide wheel to rotate under the condition that the semi-trailer transport vehicle turns. The angle sensor is used for detecting the rotation angle of the guide wheel so as to obtain the rotation angle of the traction pin and further obtain the relative angle of the semitrailer and the tractor. The angle measuring device is high in measuring accuracy, and meanwhile, the influence on the strength of the traction pin is reduced, so that the safety of the semi-trailer transport vehicle is improved.

Description

technical field [0001] The present application relates to the technical field of intelligent driving, and in particular, to an angle measuring device and a semi-trailer truck. Background technique [0002] In the field of intelligent driving, when the semi-trailer truck needs to control the trailer posture when reversing or turning, it is necessary to monitor the relative angle of the semi-trailer and the tractor in real time to realize the control of the semi-trailer truck. In the prior art, an angle sensor is usually used to measure the relative angle between the semi-trailer and the tractor, and the angle sensor is mainly installed in the following two ways. One way is to install the angle sensor on the traction pin, and install the angle sensor by drilling holes in the traction pin. This method will affect the strength of the traction pin. When the vehicle is running, the traction pin will break due to vibration, resulting in the separation of the semi-trailer and the t...
