Problems solved by technology

However, the actual production of automobiles is composed of multi-component welding and assembly. Manufacturing deviations of parts and consistency fluctuations in assembly processes will cause differences in the left and right states of the vehicle, resulting in differences in the forces on both sides when driving. As a result, the car cannot drive in a straight line, and the phenomenon of driving deviation occurs.
[0003] At present, in the main engine factory, most of the driving deviation is the test verification in the early trial production stage, and the dynamic monitoring of the vehicle off the assembly line is mostly the subjective evaluation of individuals, which is easy to cause misjudgment

Embodiment Construction

[0021] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

[0022] The invention discloses a laser measurement-based automobile straight-line deviation measurement system, which is used to detect the straight-line driving ability of the automobile, such as figure 1 As shown in , the main structure includes: a driving track 4, detection columns arranged at intervals are arranged on the side of the driving track 4, a laser sensor 7 is arranged on the detection column, and a result display board 3 is arranged at the end of the driving track 4. Among them, the laser sensor 7 is used to detect the lateral position and measurement time of the vehicle equivalent to the detection column, and output the data to the result display and processing center, after processing, it will be converted into offset distance or vehicle offset angle data and displayed on the re...

Abstract

The invention discloses an automobile linear deviation measurement system based on laser measurement and a measurement judgment method. The automobile linear deviation measurement system is characterized by comprising a running track, detection columns arranged at intervals are arranged on the side edge of the running track, laser sensors are arranged on the detection columns, and a result displayboard is arranged at the tail end of the running track. According to the automobile linear deviation measurement system based on laser measurement and the measurement judgment method, the structure is simple, online deviation detection of the whole automobile can be accurately and rapidly achieved, and the automobile linear deviation measurement system has high practicability and good applicationprospects.

Description

technical field [0001] The invention belongs to the technical field of automobile testing, and more specifically relates to a laser measurement-based automobile linear deviation measurement system and a measurement determination method. Background technique [0002] In the design state of the car, the force on the left and right sides is the same during the driving process, and the car has the characteristics of straight-line driving. However, the actual production of automobiles is composed of multi-component welding and assembly. Manufacturing deviations of parts and consistency fluctuations in assembly processes will cause differences in the left and right states of the vehicle, resulting in differences in the forces on both sides when driving. As a result, the car cannot drive in a straight line, resulting in a deviation phenomenon. [0003] At present, in OEMs, most of the driving deviation is the test verification in the early trial production stage, while the dynamic...
