Abstract

The invention relates to a system and a method for measuring a hinge angle of a full trailer train. The measuring system comprises a tractor, a trailer, at least one laser range finder, a reflecting plate, a data acquisition instrument and a data analyzer; the tractor is connected with the trailer; the at least one laser range finder is arranged at the front end of the trailer, and the reflectingplate is arranged at the rear end of the tractor; or, the at least one laser range finder is arranged at the rear end of the tractor, and the reflecting plate is arranged at the front end of the trailer; and the laser range finder, the data acquisition instrument and the data analyzer are connected in sequence. The system is simple in structure, does not need to change the train, is convenient toinstall, can achieve the real-time measurement of the hinge angle of the train in a road state without being limited by a hinge mechanism of the train, so that the lateral stability of the train is analzyed.

Description

technical field [0001] The invention relates to the field of vehicle road tests, in particular to a measurement system and method for measuring the articulation angle of a full-trailer vehicle train. Background technique [0002] With the development of automobile transportation and the continuous increase of freight volume, the load quality of automobiles is increasing continuously. Since the development of automobiles is limited by the total vehicle mass and axle load quality regulations, the most effective way to improve the load quality of automobiles is to implement trailer transportation. , Development of automobile trains. A light train is a combination of a motor tractor (passenger car of the M1 category or a pickup truck of the N1 category) and a trailer. The articulation angle is the angle between the longitudinal axis of the tractor and the longitudinal axis of the trailer. During the running of a car train, the size and rate of change of the articulation angle ...
