Embodiment Construction

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0046] like Figure 1-4 As shown, the present invention provides a kind of unilateral bridge test evaluation method, comprises the following steps:

[0047] Step S1, synchronously establish the test area model of the unilateral bridge and the motorcycle vehicle model;

[0048] In the step S1, a plurality of GPS calibration points are set in the test site to establish a single-side bridge test area model, specifically as follows:

[0049] Step S101, dividing ...

Abstract

The invention discloses a unilateral bridge examination evaluation method. The method comprises the steps of S1, synchronously establishing a unilateral bridge examination area model and a motorcycle vehicle model; and S2, respectively matching the regional relationship between the motorcycle vehicle model and the unilateral bridge examination area model to obtain the unilateral bridge examination score of the motorcycle vehicle. The examination area and the vehicle body area are matched by adopting GPS base station equipment and GPS mobile station equipment, so that the three-dimensional position and the course of the examination vehicle can be accurately measured in real time for evaluation of examination items, the information of the examination room and the examination vehicle is relatively simple, convenient and accurate to collect, and the misjudgment rate is greatly reduced. Meanwhile, compared with the adoption of two sets of GPS equipment, the cost is remarkably saved, the influence of external weather or environment change is avoided, and popularization and application are facilitated.

Description

technical field [0001] The invention relates to the technical field of motor vehicle examinations, in particular to a single-sided bridge examination evaluation method. Background technique [0002] Passing the unilateral bridge test is an item in the field test for motor vehicle drivers. Its purpose is to cultivate and assess the actual driving ability of motor vehicle drivers to correctly judge the straight-line driving trajectory of the wheels and control the non-parallel running of the vehicle in actual road driving. If during the test, the wheels of the test vehicle fall off the bridge deck, etc., the corresponding score will be determined according to the test. [0003] At present, in the driving test, the method of GPS positioning is used to gradually replace the detection method of installing various types of sensors such as photoelectric sensors, vibration sensors, magnetic sensors, and infrared sensors to test items according to the assessment standards. Therefore...
