Identification method of vehicle driving shaft

Abstract

The invention discloses an identification method of a vehicle driving shaft. The method comprises the following steps: A, a control host controls a laser radar device to scan the side contour of a vehicle to obtain scanning data, and a ground induction coil is controlled to collect chassis structural characteristics of the vehicle to obtain oscillation frequency change data; B, axle information and tire type information of the scanned vehicle are obtained according to the scanning data; C, according to the obtained axle information and the tire type information, a corresponding oscillation frequency change value in the oscillation frequency change data is obtained and comparison and determination are carried out to judge whether the axle is a driving axle or not. By means of the laser radar device and the ground induction coil, the outline of the vehicle is matched with the induction curve of the vehicle bottom, and the number and the positions of the driving shafts can be accurately recognized, so that the national legal vehicle standard can be inquired according to the shaft type information, the checked standard load quality of the vehicle can be obtained, and unmanned full-automatic overload control management is realized.

Description

technical field [0001] The invention belongs to the technical field of vehicle identification, and in particular relates to an identification method for a vehicle drive shaft, especially a truck drive shaft. Background technique [0002] The overrun control at expressway entrance is an important part of the current highway operation management. The traditional business process is that the toll collector observes the axle shape of the vehicle, checks the content of the vehicle's driving license, determines the loadable quality of the vehicle, and then compares it with the weighing data. If it is not overloaded, it is allowed to enter the expressway, otherwise it is advised to return . This work relies heavily on the experience and sense of responsibility of the operator, especially since manual identification cannot be separated, and unattended entrance management cannot be realized. [0003] The way to solve the current highway overrunning is to determine the weight limit ...

Problems solved by technology

[0009] In the above-mentioned schemes, precision sensors need to be buried and arranged on the road surface, and the equipment cost and installation cost are high; the scheme of using camera and laser scanning module at the same time will affect the recognition efficiency when the road environment is bad
