[0056] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0057] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] When users modify their vehicles, it involves the modification of components or systems that affect the performance of the entire vehicle. When modifying, the user's personal experience or simple measuring tools are usually used to evaluate whether the modification is reasonable. However, various parameters of the vehicle need to be verified and confirmed in many aspects during the design stage. Blind modification by non-professionals may cause various problems, such as product overload breakage, interference and abnormal noise from peripheral parts, etc., which may endanger the user's personal safety in serious cases. In order to solve the above problems, an embodiment of the present invention provides a vehicle modification verification method, device and vehicle. The above-mentioned vehicle modification verification method, device and vehicle are described in detail below.

[0059] First, refer to Figure 1 The embodiment of the present invention provides a vehicle modification verification method, which is used for a user to verify a vehicle before modification, and can provide a drive shaft verification result to the user based on the intended modification information input by the user before modification, thereby providing a professional modification verification to the user. The vehicle may be a vehicle with a front McPherson suspension.

[0060] The vehicle modification verification method may be specifically executed by a processor in a vehicle, and the vehicle modification verification method includes:

[0061] Step 101, in response to user input, obtaining proposed modification information.

[0062] The intended modification information is the relevant information directly input by the user for the intended modification. The vehicle modification verification software can be installed on the vehicle computer, through which the user can input information. Before starting the modification, the user first inputs the relevant information for the intended modification, and the vehicle modification verification software will provide the user with the drive shaft verification result based on the information input by the user. The user can perform the actual modification when the drive shaft verification result is qualified.

[0063] The methods of opening the vehicle modification verification software include: first, clicking the virtual software icon on the vehicle computer; second, clicking the physical button. Figure 4 The display interface of the vehicle modification verification software has an information input area, and the information input area includes an information input box for users to input information. Figure 4 The vehicle modification verification software may have a confirmation button. At this time, after the user inputs information and clicks the confirmation button, the processor will obtain the proposed modification information input by the user and execute the subsequent verification process.

[0064] Step 102: determining at least one parameter to be modified according to the proposed modification information.

[0065] Among them, the proposed modification parameters are the parameters that the user intends to modify and can be directly used for the drive shaft calibration. The proposed modification information may include tire model information, rim offset information, vibration reduction stroke information, body posture information, anti-skid chain thickness information, etc. There is a problem that the information directly input by the user cannot be directly used in the calibration process. Therefore, the proposed modification information needs to be converted into proposed modification parameters that can be directly used for the drive shaft calibration. The corresponding proposed modification parameters can be calculated based on the preset calculation formula according to the proposed modification information. The proposed modification parameters may include the proposed change in wheel center position, the proposed change in drive shaft position, the proposed change in tire rolling radius, the proposed change in rim offset, the proposed change in vibration reduction stroke, the proposed change in body posture, the proposed change in anti-skid chain thickness, etc.

[0066] Step 103: determining a parameter set to be changed according to at least one parameter to be changed and a pre-stored parameter set.

[0067] The parameter set includes all parameters used for drive shaft verification, for example, the parameter set may include suspension hard point parameters, drive shaft position, drive shaft design parameters, damping stroke, tire rolling radius, rim offset, body posture, etc. The suspension hard point parameters include wheel center position. The number of parameters included in the parameter set itself is greater than or equal to the number of parameters to be modified.

[0068] The parameter set to be modified includes at least one parameter to be modified and all parameters in the parameter set except parameters of the same type as the at least one parameter to be modified. The parameters to be modified include the wheel center position to be modified, the drive shaft position to be modified, the vibration damping stroke to be modified, the tire rolling radius to be modified, the wheel rim offset to be modified, and the vehicle body posture to be modified, which are parameters of the same type as the wheel center position, the drive shaft position, the drive shaft design parameters, the vibration damping stroke, the tire rolling radius, the wheel rim offset, and the vehicle body posture in the parameter set, respectively. The number of parameters included in the parameter set to be modified is equal to the number of parameters included in the parameter set.

[0069] One way to determine the parameter set to be modified is: copy all parameters in the parameter set except for the parameters of the same type as at least one parameter to be modified, and form the parameter set to be modified by combining at least one parameter to be modified and all parameters in the copied parameter set except for the parameters of the same type as at least one parameter to be modified. Another way to determine the parameter set to be modified is: back up the pre-stored parameter set to obtain a parameter set copy; and replace the parameters of the same type as at least one parameter to be modified in the parameter set copy based on at least one parameter to be modified to obtain the parameter set to be modified.

[0070] Step 104 , calibrate the parameter set to be modified based on a preset drive shaft calibration mechanism to obtain a drive shaft calibration result.

[0071] After step 104, analysis information can also be output and displayed based on the drive shaft calibration result. Figure 4 The display interface of the vehicle modification verification software also has a modification analysis area, and the modification analysis area includes a display frame for displaying analysis information. The drive shaft verification mechanism is a mechanism pre-set by professionals for verifying the drive shaft. The drive shaft verification mechanism may include at least one verification method used by the actual vehicle to verify the performance of the drive shaft during the research and development stage. The drive shaft verification results can be divided into qualified verification and unqualified verification. A qualified verification indicates that when the modification plan is adopted, the performance of the drive shaft meets the design requirements. An unqualified verification indicates that when the modification plan is adopted, the performance of the drive shaft does not meet the design requirements.

[0072] When users modify their vehicles, they usually change the tire size, rim offset, damping stroke, body posture, etc. The above changes will cause the state of the drive shaft to change. When the state of the drive shaft exceeds the design requirements, it may cause various problems, such as the three pins of the drive shaft coming out, the body swaying, shaking, interference with peripheral parts, etc. In this embodiment, the modification plan is verified based on the preset drive shaft verification mechanism. When the verification result of the drive shaft corresponding to the modification plan is unqualified, the modification plan is not adopted, thereby avoiding various problems of the drive shaft caused by blind modification.

[0073] In an embodiment of the present invention, at least one proposed modification parameter can be determined based on the proposed modification information input by the user, a proposed modification parameter set can be determined based on at least one proposed modification parameter and a parameter set, and the proposed modification parameter set can be calibrated based on a preset drive shaft calibration mechanism to obtain a drive shaft calibration result. That is, the vehicle modification calibration method can calibrate the modification plan through a professional calibration method based on the proposed modification information input by the user, so that the user can determine whether the modification plan is reasonable based on the drive shaft calibration result without professional knowledge, and can avoid various problems caused by blind modification due to insufficient professional knowledge, thereby ensuring the performance of the drive shaft and the safety of the user.

[0074] In an optional embodiment of the present invention, the drive shaft calibration mechanism includes at least one of a peripheral parts clearance calibration mechanism, a slip curve calibration mechanism, an allowable angle calibration mechanism, and a strength calibration mechanism. Step 104, based on a preset drive shaft calibration mechanism, the proposed modified parameter set is calibrated to obtain a drive shaft calibration result, including: calibrating the proposed modified parameter set based on the peripheral parts clearance calibration mechanism, and / or calibrating the proposed modified parameter set based on the slip curve calibration mechanism, and / or calibrating the proposed modified parameter set based on the allowable angle calibration mechanism, and / or calibrating the proposed modified parameter set based on the strength calibration mechanism to obtain a drive shaft calibration result.

[0075] Among them, the peripheral parts clearance check mechanism is also a mechanism for checking the dynamic clearance between the drive shaft and the peripheral parts. The method for checking the dynamic clearance between the drive shaft and the peripheral parts based on the peripheral parts clearance check mechanism may include: establishing a spatial model of the drive shaft and its peripheral parts; simulating the motion trajectory of the drive shaft of the vehicle under different load, steering and suspension changes according to the drive shaft design parameters and the drive shaft position; measuring the clearance range between the drive shaft and the peripheral parts during the entire motion trajectory; and judging whether the clearance range meets the clearance requirements between the drive shaft and the peripheral parts.

[0076] The slip curve verification mechanism is a mechanism for verifying the slip curve of the drive shaft. The method for verifying the slip curve of the drive shaft based on the slip curve verification mechanism may include: establishing a slip curve model of the drive shaft; analyzing the slip rate of the drive shaft in various typical driving scenarios; measuring the key nodes of the slip curve; and comparing and verifying with the standard slip curve. Among them, the key nodes may include the initial slip point, the maximum slip rate point, and the slip rate drop point.

[0077] The permissible angle verification mechanism is a mechanism for verifying the permissible angle of the drive shaft. The method for verifying the permissible angle of the drive shaft based on the permissible angle verification mechanism may include: establishing a spatial model of the drive shaft; analyzing the angle changes under different working conditions; measuring the maximum working angle of the drive shaft; and comparing and verifying the measured maximum working angle of the drive shaft with the designed permissible angle.

[0078] The strength verification mechanism is a mechanism for verifying the strength of the drive shaft. Methods for verifying the strength of the drive shaft based on the strength verification mechanism may include: establishing a mechanical model of the drive shaft; analyzing the stress distribution under different working conditions; measuring the maximum stress of the drive shaft, and comparing the measured maximum stress with the design strength.

[0079] In this embodiment, the parameter set to be modified can be checked based on multiple aspects, so as to ensure that when the check result of the drive shaft is qualified, all performances of the drive shaft can meet the requirements.

[0080] In an optional embodiment of the present invention, the parameter set includes at least wheel center position, drive shaft position, drive shaft design parameters, vibration reduction stroke, tire rolling radius, rim offset, and vehicle body posture; the proposed modification information includes at least one of tire model information, rim offset information, vibration reduction stroke information, vehicle body posture information and anti-skid chain thickness information.

[0081] Step 102, determining at least one parameter to be modified based on the information on the proposed modification, including: determining the proposed modified wheel center position and the proposed modified drive shaft position based on the tire model information and / or the rim offset and / or the body posture information and / or the anti-skid chain thickness information; and / or determining the proposed modified tire rolling radius based on the tire model information and / or the anti-skid chain thickness information; and / or determining the proposed modified rim offset based on the rim offset information; and / or determining the proposed modified damping stroke based on the damping stroke information; and / or determining the proposed modified body posture based on the body posture information, or determining the proposed modified body posture based on the tire model information and / or the anti-skid chain thickness information.

[0082] Reference Figure 4 The information input area specifically includes five independent information input boxes, which are tire model input box, rim offset input box, damping stroke input box, vehicle body posture input box and anti-skid chain thickness input box. The tire model information in the proposed modification information is the information entered by the user in the tire model input box, the rim offset information is the information entered by the user in the rim offset input box, the damping stroke information is the information entered by the user in the damping stroke input box, the vehicle body posture information is the information entered by the user in the vehicle body posture input box, and the anti-skid chain thickness information is the information entered by the user in the anti-skid chain thickness input box.

[0083] The wheel center position may refer to the position of the wheel center relative to the vehicle body. The drive shaft position may refer to the position of the drive shaft relative to the vehicle body. The drive shaft design parameters may include the drive shaft length, drive shaft diameter, drive shaft material, drive shaft shape, drive shaft stiffness, etc. The vehicle body posture in the parameter set specifically refers to the wheel eyebrow height value, that is, the distance between the wheel eyebrow and the ground along the height direction of the vehicle. The unit of the wheel eyebrow height value may be mm. The units of the rim offset and vibration reduction stroke in the parameter set may both be mm. The vehicle body posture input by the user also refers to the wheel eyebrow height value, and the unit is also mm. The units of the rim offset, vibration reduction stroke, and anti-skid chain thickness input by the user are also mm.

[0084] The rolling radius of the tire, the wheel center position, and the drive shaft position can be determined based on the proposed modification information and a preset calculation formula. For example, the method for determining the rolling radius of the tire to be modified based on the tire model information can be: determining the width, aspect ratio, type, and rim diameter of the tire based on the tire model information, and calculating the rolling radius of the tire to be modified based on the width, aspect ratio, rim diameter, and a preset tire rolling radius calculation method. The method for determining the wheel center position to be modified based on the tire model information can be: determining the width, aspect ratio, type, and rim diameter of the tire based on the tire model information, and calculating the wheel center position to be modified based on the width, aspect ratio, rim diameter, and a preset wheel center position calculation method.

[0085] When determining the proposed change in rim offset based on rim offset information, if the rim offset information only contains numbers but no units, the proposed change in rim offset is the same as the rim offset information. When determining the proposed change in vibration reduction stroke based on vibration reduction stroke information, if the vibration reduction stroke information only contains numbers but no units, the proposed change in vibration reduction stroke is the same as the vibration reduction stroke information. When determining the proposed change in body posture based on body posture information, if the body posture information only contains numbers but no units, the proposed change in body posture is the same as the body posture information.

[0086] Changes in tire size, rim offset, damping stroke, vehicle body posture and the like will cause changes in the state of the drive shaft. In an embodiment of the present invention, the proposed modification parameters are jointly determined based on the tire model information, rim offset information, damping stroke information, vehicle body posture information and anti-skid chain thickness information, so that the final determined set of proposed modification parameters is more comprehensive, thereby ensuring the accuracy of the verification.

[0087] In an optional embodiment of the present invention, when the user clicks on the information input box to start inputting information, input prompt information can be output and displayed in response to the user's click operation on the information input box. The input prompt information can be suspended above the information input box. Different information input boxes correspond to different input prompt information. For example, the input prompt information corresponding to the tire model input box can be "Please enter the tire model you want to modify, such as 245 / 45R18, please confirm that the input format is correct; if this modification does not involve this item, please skip"; the input prompt information corresponding to the rim offset input box can be "Please enter the rim offset you want to modify, such as 45 (if it is a negative value, it should be -45), the unit is mm, please pay attention to the positive and negative signs; if this modification does not involve this item, please skip"; the input prompt information corresponding to the shock absorbing stroke input box can be "Please enter the rim offset you want to modify, such as 45 (if it is a negative value, it should be -45), the unit is mm, please pay attention to the positive and negative signs; if this modification does not involve this item, please skip"; the input prompt information corresponding to the shock absorbing stroke input box can be "Please enter the rim offset you want to modify The damping stroke is in mm, and the input box on the left is for the lower jump stroke (e.g. -90), and the input box on the right is for the upper jump stroke (e.g. 85). The unit is mm, and please pay attention to the positive and negative signs; if this modification does not involve this item, please skip it"; the input prompt information corresponding to the body posture input box can be "Please enter the body posture after your modification, that is, the wheel arch height value, such as 1200, in mm; if this modification does not involve this item, please skip it"; the input prompt information corresponding to the anti-skid chain thickness input box can be "Please enter the thickness of the anti-skid chain you want to modify, such as 20, in mm; if this modification does not involve this item, please skip it".
