[0028] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0029] In related technologies, in order to optimize the overlap between the torque manager and the drive shaft, testers usually manually adjust the relative position of the torque manager and the drive shaft, and use a dynamic balancing analyzer to evaluate whether the adjusted position is balanced during the adjustment process. It is usually necessary to repeat the above work several times before the position matching of the torque manager and the drive shaft can be completed to eliminate the shaking problem. The drive shaft debugging of this technology relies too much on the experience of the tester, and requires the assistance of a dynamic balancing analyzer for debugging, resulting in high labor and equipment costs for drive shaft debugging, and a long time required for manual debugging of the drive shaft, which greatly reduces the efficiency of drive shaft debugging.

[0030] Therefore, the present application proposes a drive shaft debugging method, which first obtains the actual model of the target vehicle, determines the reference amplitude data of the target vehicle according to the actual model, quickly and accurately determines the actual relative position by combining the actual amplitude and the reference amplitude, and then generates a debugging action that quickly approaches the target by combining the actual relative position and the target matching position, thereby providing a basis for drive shaft debugging, and realizing drive shaft debugging through the amplitude of the vehicle, without relying on the experience of the tester and the assistance of a dynamic balancing analyzer, effectively reducing the labor cost and equipment cost required for drive shaft debugging, and when the debugging action is clear, the time required for debugging can be effectively shortened, and the efficiency of drive shaft debugging can be effectively improved.

[0031] The following describes the drive shaft debugging method, device, equipment, vehicle and medium of the embodiments of the present application with reference to the accompanying drawings.

[0032] Specifically, Figure 1 A schematic flow chart of a transmission shaft debugging method provided in an embodiment of the present application.

[0033] like Figure 1 As shown, the transmission shaft debugging method includes the following steps:

[0034] In step S101, the actual model of the target vehicle is obtained.

[0035] Among them, the target vehicle refers to the vehicle that needs to debug the drive shaft, and the actual model refers to the actual model of the vehicle, such as sedans, SUVs (Sport utility vehicles), MPVs (Multi-Purpose Vehicles) and pickup trucks, which can be divided into different levels of models according to wheelbase, body length, load, etc.

[0036] It is understandable that the purpose of drive shaft debugging is to match the torque manager and the drive shaft to eliminate jitter, and the size type and other parameters of the drive shaft corresponding to different vehicle models are different. Therefore, when debugging the drive shaft in the embodiment of the present application, it is necessary to first clarify the actual model of the target vehicle, and improve the accuracy of the drive shaft debugging by clarifying the actual model.

[0037] It should be noted that the embodiments of the present application can obtain the actual model of the target vehicle in a variety of ways, for example, reading the VIN (Vehicle Identification Number) of the target vehicle. The VIN code is usually bound to the vehicle information, and the actual model can be obtained by identifying the vehicle signal; for example, obtaining an image of the target vehicle, and determining the actual model of the target vehicle through image recognition and big data comparison.

[0038] In step S102, reference amplitude data of the target vehicle is determined according to the actual model, wherein the reference amplitude data includes reference amplitudes between respective reference points of the torque manager and the transmission shaft of the target vehicle at a plurality of relative positions.

[0039] Among them, the torque manager and the drive shaft are both set with reference points. The reference point of the torque manager is the heavy point, and the drive shaft is the light point. The weight at the heavy point is greater than the weight at the light point. The matching of the light and heavy points means adjusting the relative positions of the torque manager and the drive shaft so that their weight distribution is as balanced as possible to reduce or eliminate the jitter caused by weight imbalance.

[0040] It can be understood that since the relative position of the torque manager and the drive shaft after installation is not fixed and there are different relative positions, in order to be able to quickly and accurately determine the actual relative position, the embodiment of the present application pre-calibrates the reference amplitudes of the respective reference points of the torque manager and the drive shaft at different relative positions. After calibration, the reference amplitude data and the actual model of the vehicle are bound to obtain a target binding relationship. In specific applications, the parameter amplitude data corresponding to the actual model can be quickly and accurately determined based on the target binding relationship.

[0041] Specifically, the specific calibration process of the reference amplitude is as follows:

[0042] (1) First determine the number of relative positions and vehicle models that need to be calibrated;

[0043] (2) calibrating multiple test vehicles of the same model, adjusting the torque manager and the drive shaft of each test vehicle to different relative positions, and detecting the amplitude using a vibration sensor at each relative position;

[0044] (3) Analyze the amplitude data of multiple test vehicles, remove noise points in the amplitude data, such as points with obvious abnormal data, and determine reference amplitude data based on the analysis results.

[0045] In step S103, the actual relative position between the torque manager and the respective reference points of the drive shaft is determined according to the reference amplitude data and the actual amplitude of the target vehicle, a target debugging action of the drive shaft is generated according to the actual relative position and the target matching position, and the drive shaft is debugged based on the target debugging action, wherein the target matching position is the relative position with the smallest amplitude among multiple relative positions.

[0046] It can be understood that since the reference amplitude can accurately represent the multiple relative positions between the reference points of the torque manager and the drive shaft, the embodiment of the present application can combine the actual amplitude and the reference amplitude to quickly and accurately determine the actual relative position. At the same time, the target matching position is the target of the final debugging. Combining the actual relative position and the target matching position can give a debugging action that quickly approaches the target. The reference amplitude data is the basis for debugging the drive shaft, thereby providing a theoretical basis for debugging the drive shaft, and can give a clear debugging direction during debugging without relying on the experience of the tester and the assistance of the dynamic balancing analyzer, effectively reducing the labor cost and equipment cost required for debugging the drive shaft. When the debugging action is clear, the time required for debugging can be effectively shortened, and the efficiency of debugging the drive shaft can be effectively improved.

[0047] In an embodiment of the present application, the actual relative positions of the reference points of the torque manager and the drive shaft are determined based on the reference amplitude data and the actual amplitude of the target vehicle, including: identifying the reference amplitude that matches the actual amplitude in the reference amplitude data; and determining the actual relative position based on the relative position corresponding to the reference amplitude.

[0048] It can be understood that the embodiment of the present application determines the actual relative position corresponding to the actual amplitude by querying the reference amplitude data, thereby obtaining the actual relative position of the reference points of the target vehicle torque manager and the drive shaft, so that when the drive shaft is subsequently debugged, the reference point position can be quickly found for debugging, saving debugging time. If the reference amplitude data does not have a reference amplitude equal to the actual amplitude, the reference amplitude closest to the actual amplitude is selected.

[0049] In an embodiment of the present application, a target debugging action of the transmission shaft is generated according to the actual relative position and the target matching position, including: determining the position matching level between the torque manager and the respective reference points of the transmission shaft according to the actual relative position and the target matching position, and determining the target debugging action according to the position matching level.

[0050] Among them, the position matching level refers to the relative distance between the reference points of the torque manager and the transmission shaft. The position matching level is determined based on the target relative position and the actual relative position, taking the target relative position as the benchmark. For example, if the target relative position is the shortest relative distance between the reference points, the position matching level corresponding to the target relative position is the highest level. The farther the relative distance between the reference points, the lower the corresponding position matching level.

[0051] It can be understood that since the position matching level indicates the actual matching degree between the torque manager and the drive shaft, the relative distances under different matching degrees are different, so the corresponding debugging actions during specific debugging are also different. The embodiment of the present application can determine the position matching level according to the actual relative position and the target relative position, and then determine the target debugging action suitable for the current situation according to the selected position matching level, thereby effectively clarifying the debugging direction, completing the debugging work quickly and accurately, effectively reducing the number of debugging times, and reducing debugging costs.

[0052] For example, based on the position of the mounting screws, the torque manager and the transmission shaft can be divided into six areas, each area occupies a 60° position, and the position matching level of the light and heavy points can be divided into three position matching levels, namely the first to third position matching levels, where, for example Figure 4 As shown, the third position matching level is when the relative positions of the light and heavy points are relatively close; Figure 5 As shown, the second position matching level is when the light and heavy points are relatively far away; Figure 6 As shown, the third position matching level is when the light and heavy points are at the farthest relative position. Due to the different relative positions of the light and heavy points, the angles of rotation of the transmission shaft are also different. For example, at the first position matching level, there is no need to rotate the transmission shaft. For example, at the second position matching level, the transmission shaft can be rotated clockwise or counterclockwise; for another example, at the third position matching level, the transmission shaft can be rotated 180° clockwise or counterclockwise to achieve position matching. Since the relative position and target position are clear, the rotation direction and angle can be determined, which can effectively clarify the debugging direction, quickly and accurately complete the debugging work, effectively reduce the number of debugging times, and reduce the debugging cost.

[0053] Therefore, the target debugging action may include rotating the transmission shaft clockwise or counterclockwise. In an embodiment of the present application, debugging the transmission shaft based on the target debugging action includes: rotating the transmission shaft in the target rotation direction corresponding to the target debugging action; after debugging the transmission shaft based on the target debugging action, it also includes: if the actual amplitude reaches the target amplitude, completing the debugging of the transmission shaft; if the actual amplitude decreases, continuing to rotate in the target rotation direction; if the actual amplitude increases, rotating in the direction opposite to the target rotation direction.

[0054] It can be understood that if the actual amplitude reaches the target amplitude, it means that the transmission shaft has been debugged to reach the specified position, and the debugging meets the final standard, so that the debugging work can be completed; if the actual amplitude decreases after the transmission shaft is debugged based on the target debugging action, it means that the debugging direction is correct, and then continue to rotate in the target rotation direction; if the actual amplitude increases after the transmission shaft is debugged based on the target debugging action, it means that the debugging direction is wrong. At this time, rotate in the opposite direction of the target rotation direction. Since part of the angle has been rotated in the wrong direction, the rotation angle that has been rotated in the opposite direction of the target rotation direction is greater than the rotation angle in the target rotation direction, so that the target position can be approached more quickly, which can effectively reduce the number of debugging times and improve debugging efficiency.

[0055] For example, the target matching position is set when the relative positions of the light and heavy points are closest, and when performing vibration tests on vehicles of the same model, the reference amplitude corresponding to the farthest relative positions of the reference points of the torque manager and the transmission shaft is collected in advance. Figure 4 As shown in the figure, when the amplitude of data collection and evaluation is small and the relative positions of the light and heavy points are close, the light and heavy points can be matched by simply rotating one screw hole in the direction of decreasing amplitude or rotating two screw holes in the opposite direction of increasing amplitude. Figure 5 As shown in the figure, when the amplitude of data collection and evaluation is large and the relative position of the light and heavy points is far away, it is only necessary to rotate the two screw holes in the direction of decreasing the amplitude, or compare the amplitude data of the farthest matching point in the reference amplitude data in the direction of increasing the amplitude. When the amplitude data of the farthest matching point is reached, directly rotate 180 degrees to complete the light and heavy point matching; Figure 6 As shown, when the data collection and evaluation amplitude is large and the light-weighted point position is the farthest, it is only necessary to compare the amplitude data of the farthest matching point in the reference amplitude data. When the amplitude data of the farthest matching point is reached, it is directly rotated 180 degrees to complete the light-weighted point matching.

[0056] According to the transmission shaft debugging method proposed in the embodiment of the present application, the actual model of the target vehicle is first obtained, and the reference amplitude data of the target vehicle is determined according to the actual model. The actual relative position is quickly and accurately determined in combination with the actual amplitude and the reference amplitude, and then the debugging action of quickly approaching the target is generated in combination with the actual relative position and the target matching position, thereby providing a basis for transmission shaft debugging and realizing transmission shaft debugging through the amplitude of the vehicle. In this way, the problems of excessive reliance on the experience of testers and the assistance of dynamic balancing analyzers, increased debugging costs, and reduced debugging efficiency in the transmission shaft debugging process of related technologies are solved.

[0057] Next, the transmission shaft debugging device proposed according to the embodiment of the present application is described with reference to the accompanying drawings.

[0059] like Figure 7 As shown, the transmission shaft debugging device 30 includes: an acquisition module 310 , a determination module 320 and a debugging module 330 .

[0060] Among them, the acquisition module is used to obtain the actual model of the target vehicle; the determination module is used to determine the reference amplitude data of the target vehicle according to the actual model, wherein the reference amplitude includes the reference amplitudes between the torque manager of the target vehicle and the respective reference points of the drive shaft at multiple relative positions; the debugging module is used to determine the actual relative position between the torque manager and the respective reference points of the drive shaft according to the reference amplitude data and the actual amplitude of the target vehicle, generate a target debugging action of the drive shaft according to the actual relative position and the target matching position, and debug the drive shaft based on the target debugging action, wherein the target matching position is the relative position with the smallest amplitude among the multiple relative positions.

[0061] It should be noted that the aforementioned explanation of the embodiment of the transmission shaft debugging method is also applicable to the transmission shaft debugging device of this embodiment, and will not be repeated here.

Then, the actual relative position between the torque manager and each reference point of the transmission shaft corresponding to the actual amplitude of the target vehicle is queried by comparing the reference amplitude, and a target debugging action of the transmission shaft is generated. Based on the target debugging action, the transmission shaft is debugged to the relative position with the smallest amplitude among multiple relative positions. Thus, the problems of increased labor, detection and debugging costs caused by the related technology of using vibration sensors with their corresponding verification equipment to detect and debug the relative position of the torque manager and the transmission shaft are solved.
