[0030] Embodiment 1

[0031] Figure 1 A flow chart of a method for generating a vehicle styling effect diagram is provided for the first embodiment of the present invention. This embodiment can be applied to the process of designing and selecting the whole vehicle styling. In order to avoid the situation where the vehicle energy consumption is affected by the large drag coefficient of the whole vehicle, the method can be executed by a vehicle styling effect diagram generating device. The vehicle styling effect diagram generating device can be implemented in the form of hardware and / or software. The vehicle styling effect diagram generating device can be configured in an electronic device. Figure 1 As shown, the method includes:

[0032] S110, determining a plurality of groups of initial vehicle body models that satisfy the whole vehicle drag coefficient condition; each initial vehicle body model corresponds to a parameter variable value of its own whole vehicle body parameter variable.

[0033] In an optional solution of this embodiment, it can be combined with one or more optional solutions of this embodiment. Optionally, the vehicle body parameter variables include vehicle variables and body variables; the vehicle variables include at least one of vehicle height, ground clearance, front overhang length and approach angle; the body variables include at least one of windshield inclination, roof inclination, cab width, cab windshield width, cab height and cab length. Among them, the vehicle variables can be data variables for adjusting the state of the vehicle body, and the body variables can be data variables for adjusting the state of part of the body.

[0034] The vehicle drag coefficient condition may be a condition for designing a vehicle body model with the goal of minimizing the vehicle drag coefficient.

[0035] The initial vehicle body model may be a vehicle body model generated by the vehicle body parameter variables obtained according to the goal of achieving the minimum drag coefficient of the vehicle. The vehicle body parameter variables may be vehicle variables and body variables set according to preset conditions, and may specifically be vehicle variables and body variables set according to dimensions such as styling aesthetics, space dimensions, and human-machine comfort. Exemplarily, the vehicle body parameter variables may be automatically generated according to preset conditions.

[0036] Specifically, the parameter variable values ​​of the vehicle body parameter variables are determined with the minimum drag coefficient as the target, and then the initial body model is generated according to the determined parameter variable values ​​of the vehicle body parameter variables. Exemplarily, the vehicle variables and the body variables are automatically set by the body model generation device with the minimum drag coefficient as the target, and the corresponding initial body model is generated, which is not specifically limited in this embodiment.

[0037] S120 , adjusting the parameter variable values ​​of the vehicle body parameter variables of each initial body model according to the standard value range interval corresponding to the vehicle body parameter variables, and generating calibration body models corresponding to each initial body model.

[0038] Among them, the standard value range interval can be the value range of the parameter variable value of the vehicle body parameter variable when performing vehicle styling design. For example, the standard value range interval of the approach angle can be between 15° and 25°.

[0039] The calibrated vehicle body model may be a vehicle body model generated by adjusting the vehicle body parameter variables that are not within the standard value range according to the standard value range.

[0040] It should be noted that since the parameter variable values ​​of the vehicle body parameter variables of the initial body model are generated with the minimum drag coefficient as the goal, in order to meet the optimal target, there may be some parameter variable values ​​of the vehicle body parameter variables that are not within their own standard value range. Therefore, it is necessary to adaptively adjust the parameter variable values ​​that are not within the standard range. Due to the interaction and mutual influence between different vehicle body parameter variables, when the parameter variable value of any vehicle body parameter variable is changed, the parameter variable values ​​of other vehicle body parameter variables also need to be adaptively adjusted according to their action relationship and influence to ensure that the interaction relationship between the parameter variables is not changed.

[0041] For example, continuing the above example, if the approach angle in the initial body model is 10° (the parameter variable value is not within the standard value range of 15° to 25°), the parameter variable value of the approach angle needs to be adjusted, and the parameter variable values ​​of other vehicle body parameter variables are adaptively adjusted to obtain the adjusted parameter variable values ​​of the vehicle body parameter variables. Then, a calibration body model corresponding to the initial body model is generated according to the adjusted parameter variable values ​​of the vehicle body parameter variables.

[0042] S130: Determine a target vehicle body model according to the parameter variable values ​​of the vehicle body parameter variables of each calibration vehicle body model.

[0043] For example, determining the vehicle body model that meets the preset conditions may be to use numerical wind tunnel software to calculate the aerodynamic drag value of the corresponding vehicle body model based on the adjusted parameter variable values ​​of the vehicle body parameters. Further, the target vehicle body model is determined based on the calculated aerodynamic drag value.

[0044] Optionally, the target body model is determined according to the parameter variable values ​​of the whole vehicle body parameter variables of each calibration body model, including: determining the aerodynamic drag values ​​corresponding to each calibration body model according to the parameter variable values ​​of the whole vehicle body parameter variables of each calibration body model; determining the target body model according to the aerodynamic drag values ​​corresponding to each calibration body model.

[0045] The aerodynamic drag value may be the air drag value of the vehicle body during driving. The calculation method may be preset by relevant technicians based on experience, such as using numerical wind tunnel software for simulation calculation, which is not specifically limited in this embodiment.

[0046] Specifically, the aerodynamic drag value results of each calibration body model can be calculated according to the parameter variable values ​​of the vehicle body parameter variables corresponding to each calibration body model, and then the target body model can be determined according to the calculated aerodynamic drag value results.

[0047] Optionally, determining the target vehicle body model according to the aerodynamic drag values ​​corresponding to the calibration vehicle body models includes: determining the calibration vehicle body model having the smallest aerodynamic drag value as the target vehicle body model.

[0048] Specifically, in order to be more in line with the actual vehicle usage scenario, the calibration vehicle body model with the smallest aerodynamic resistance value can be determined as the target body model according to the calculated aerodynamic resistance value results corresponding to each calibration body model. For example, if there are calibration body model a, calibration body model b and calibration body model c, and the aerodynamic resistance value of calibration body model a is calculated to be 0.2, the aerodynamic resistance value of calibration body model b is 0.5, and the aerodynamic resistance value of calibration body model c is 0.3, then according to the calculated aerodynamic resistance value results, among calibration body model a, calibration body model b and calibration body model c, the calibration body model with the smallest aerodynamic resistance value result can be determined as the target body model. Specifically, if the smallest aerodynamic resistance value result of calibration body model a is 0.2, calibration body model a can be determined as the target body model.

[0049] It should be noted that the aerodynamic drag values ​​of different calibrated vehicle body models may be the same or different.

[0050] Correspondingly, the target body model is determined according to the aerodynamic drag values ​​corresponding to each calibration body model, including: selecting at least one reference body model according to the aerodynamic drag values ​​corresponding to each calibration body model; and determining the target body model according to the parameter variable values ​​of the vehicle body parameter variables of each reference body model.

[0051] For example, if there are calibration body model d, calibration body model e and calibration body model f, and the aerodynamic drag value of calibration body model d is calculated to be 0.3, the aerodynamic drag value of calibration body model e is 0.5 and the aerodynamic drag value of calibration body model f is 0.3, then the calibration body model d and the calibration body model f can be used as reference body models based on the calculated aerodynamic drag value results.

[0052] Specifically, the target body model is determined according to the parameter variable values ​​of the whole vehicle body parameter variables of each reference body model, which can be to obtain the parameter variable values ​​of the whole vehicle body parameter variables of at least one selected reference body model, and determine the target body model according to the dimensions of styling aesthetics, spatial dimensions, human-machine comfort, etc. Continuing with the above example, if the reference body models are calibration body model d and calibration body model f, the parameter variable values ​​of the whole vehicle body parameter variables of each reference body model are obtained, wherein the length of the cab of calibration body model d is 1.1 meters, the width of the cab is 1 meter, and the height of the cab is 1.7 meters; the length of the cab of calibration body model d is 0.8 meters, the width of the cab is 0.6 meters, and the height of the cab is 1.2 meters, then it can be considered that the calibration body model d is better than the calibration body model f in terms of spatial dimensions and human-machine interaction. Therefore, the calibration body model d can be determined as the target body model.

[0053] S140: Generate a vehicle styling rendering according to the parameter variable values ​​of the vehicle body parameter variables of the target vehicle body model.

[0054] The vehicle styling rendering may be a final vehicle styling design drawing generated according to parameter variable values ​​of the vehicle body parameter variables corresponding to the target vehicle body model.

[0055] The technical solution of the embodiment of the present invention determines multiple groups of initial body models that meet the conditions of the whole vehicle drag coefficient; adjusts the parameter variable values ​​of the whole vehicle body parameter variables of each initial body model according to the standard value range interval corresponding to the whole vehicle body parameter variables, and generates calibration body models corresponding to each initial body model; determines the target body model according to the parameter variable values ​​of the whole vehicle body parameter variables of each calibration body model; generates a vehicle styling rendering according to the parameter variable values ​​of the whole vehicle body parameter variables of the target body model. This technical solution can generate a body model by determining the corresponding whole vehicle body parameter variables that meet the conditions of the whole vehicle drag system; combines the whole vehicle drag coefficient conditions and the whole vehicle body parameter variables to achieve the rendering design of the low drag coefficient of the whole vehicle, and solves the problem of affecting the energy consumption of the whole vehicle due to the large drag coefficient of the whole vehicle.

[0056] Embodiment 2

[0057] Figure 2 A flowchart of a method for generating a vehicle styling effect diagram provided in Embodiment 2 of the present invention. Figure 2 This is a flow chart of a method for generating a vehicle styling rendering provided in the second embodiment of the present invention. Based on the above embodiments, this embodiment further optimizes the above method for generating a vehicle styling rendering.

[0058] Furthermore, the step of "adjusting the parameter variable values ​​of the vehicle body parameter variables of each initial body model according to the standard value range interval corresponding to the vehicle body parameter variables to generate a calibrated body model corresponding to each initial body model" is refined into "for any initial body model, according to the parameter variable values ​​of the vehicle body parameter variables of the initial body model, based on the standard value range interval corresponding to the vehicle body parameter variables, determining the problem parameter variables in the initial body model that do not meet the value range judgment condition; according to the standard value range interval corresponding to the problem parameter variables, numerically updating the parameter variable values ​​of the problem parameter variables to obtain updated variable values; according to the updated variable values ​​of the problem parameter variables, adjusting the parameter variable values ​​of other parameter variables until the vehicle body parameter variables all meet the value range judgment condition to obtain the calibrated body model of the initial body model; other parameter variables are parameter variables in the vehicle body parameter variables except the problem parameter variables" to improve the vehicle styling rendering generation method. Figure 2 As shown, the method includes:

[0059] S210, determining a plurality of groups of initial vehicle body models that satisfy the whole vehicle drag coefficient condition; each initial vehicle body model corresponds to a parameter variable value of its own whole vehicle body parameter variable.

[0060] S220. For any initial vehicle body model, according to the parameter variable values ​​of the vehicle body parameter variables of the initial vehicle body model and based on the standard value range interval corresponding to the vehicle body parameter variables, determine the problematic parameter variables in the initial vehicle body model that do not meet the value range judgment condition.

[0061] The value range judgment condition may be used to determine whether the vehicle body parameter variable is within the corresponding standard value range. The problem parameter variable may be a vehicle body parameter variable that is not within the standard value range among the vehicle body parameter variables.

[0062] Among them, determining the problem parameter variables that do not meet the value range judgment conditions in the initial body model can specifically be to compare the parameter variable values ​​of each vehicle body parameter variable corresponding to the initial body model with the corresponding standard value range interval, and determining the problem parameter variables that do not meet the range judgment conditions in the initial body model based on the comparison results.

[0063] For example, if the wheelbase of the initial vehicle body model is obtained to be 2.8 meters and the ground clearance is 1 meter, where the standard value range corresponding to the wheelbase can be 1.5 meters to 3.5 meters, and the standard value range corresponding to the ground clearance can be 0.2 meters to 0.7 meters, then it can be determined that the wheelbase of the initial vehicle body model meets the standard value range, while the ground clearance does not meet the standard value range, and the ground clearance can be considered to be a problematic parameter variable.

[0064] S230 . According to the standard value range interval corresponding to the problem parameter variable, the parameter variable value of the problem parameter variable is numerically updated to obtain an updated variable value.

[0065] Specifically, according to the standard value range interval corresponding to the problem parameter variable, the parameter variable value of the problem parameter variable can be adjusted to be within the corresponding standard value range interval, so that the adjusted parameter variable value is determined as the updated variable value.

[0066] Continuing with the above example, if the height of the initial vehicle body model is 2 meters, the corresponding standard value range may be 0.8 meters to 1.5 meters, and the height of the initial vehicle body model may be adjusted to 1.5 meters. The height of the initial vehicle body model may be updated according to the adjusted height value to obtain an updated height value.

[0067] S240. According to the updated variable value of the problem parameter variable, adjust the parameter variable values ​​of other parameter variables until the whole vehicle body parameter variables all meet the value range judgment condition, and obtain the calibrated body model of the initial body model; wherein the other parameter variables are the parameter variables in the whole vehicle body parameter variables except the problem parameter variables.

[0068] Due to the specific correlation between the vehicle body parameter variables, when any vehicle body parameter variable is adjusted, other parameter variables also need to be adaptively adjusted accordingly. Continuing with the above example, the body height of the initial body model is adjusted from 2 meters to 1.5 meters, and the updated variable value of the body height of the initial body model is 1.5 meters. Furthermore, according to the updated variable value of the body height of the initial body model, the ground clearance and cab height of the initial body model are adjusted accordingly. It should be noted that the parameter variable values ​​of other parameter variables can be adjusted manually or automatically according to the corresponding relationship between the variables. The adjustment is iterated until all the vehicle body parameter variables of the initial body model meet the value range judgment condition, thereby generating a calibrated body model of the initial body model.

[0069] S250: Determine a target vehicle body model according to the parameter variable values ​​of the vehicle body parameter variables of each calibration vehicle body model.

[0070] S260: Generate a vehicle styling rendering according to the parameter variable values ​​of the vehicle body parameter variables of the target vehicle body model.

[0071] In an optional scheme of the present embodiment, it can be combined with one or more optional schemes of the present embodiment. Optionally, according to the standard value range interval corresponding to the whole vehicle body parameter variable, the parameter variable value of the whole vehicle body parameter variable of each initial body model is adjusted to generate a calibrated body model corresponding to each initial body model, including: for any initial body model, according to the parameter variable value of the whole vehicle body parameter variable of the initial body model, based on the standard value range interval corresponding to the whole vehicle body parameter variable, determine the problem parameter variable in the initial body model that does not meet the value range judgment condition; according to the standard value range interval corresponding to other parameter variables, numerically update the parameter variable value of other parameter variables to obtain updated variable value; other parameter variables are parameter variables in the whole vehicle body parameter variables except the problem parameter variable; according to the updated variable value of other parameter variables, adjust the parameter variable value of the problem parameter variable until the whole vehicle body parameter variables all meet the value range judgment condition, and obtain the calibrated body model of the initial body model.

[0072] For example, if the approach angle of the initial vehicle body model is 30°, the vehicle body height is 1.2 meters, and the ground clearance is 0.3 meters, where the standard value range of the approach angle can be 15° to 25°, the standard value range of the vehicle body height can be 0.8 meters to 1.7 meters, and the standard value range of the ground clearance can be 0.2 meters to 0.4 meters, then it can be determined that the problematic parameter variable that does not meet the value range judgment condition in the initial vehicle body model is the approach angle, and the other parameter variables are the vehicle body height and the ground clearance.

[0073] Furthermore, other parameter variables can be adjusted according to the standard value range of other variables, such as the vehicle height can be adjusted to 1.7 meters and the ground clearance can be adjusted to 0.4 meters. Furthermore, according to the interaction and mutual influence between the vehicle body parameter variables, the approach angle can be adjusted to 22°, so that the vehicle body parameter variables all meet the value range judgment conditions, and thus generate a calibrated body model of the initial body model.

[0074] In another optional scheme of the present embodiment, one or more optional schemes of the present embodiment can be combined. Optionally, according to the standard value range interval corresponding to the whole vehicle body parameter variable, the parameter variable value of the whole vehicle body parameter variable of each initial body model is adjusted to generate a calibration body model corresponding to each initial body model, including: for any initial body model, according to the parameter variable value of the whole vehicle body parameter variable of the initial body model, based on the standard value range interval corresponding to the whole vehicle body parameter variable, determine the problem parameter variable and the corresponding parameter variable value in the initial body model that do not meet the value range judgment condition; according to the standard value range interval corresponding to other parameter variables, the parameter variable value of other parameter variables is numerically updated to obtain an updated variable value corresponding to the parameter variable value of the problem parameter variable; the other parameter variables are parameter variables other than the problem parameter variables in the whole vehicle body parameter variables; according to the updated variable values ​​of other parameter variables and the parameter variable values ​​of the problem parameter variables, obtain the calibration body model of the initial body model.

[0075] For example, if the approach angle of the initial body model is 13°, the body height is 1 meter, and the ground clearance is 0.25 meters, the standard value range of the approach angle can be 15° to 25°, the standard value range of the body height can be 0.8 meters to 1.7 meters, and the standard value range of the ground clearance can be 0.2 meters to 0.4 meters, then it can be determined that the problem parameter variable that does not meet the value range judgment condition in the initial body model is the approach angle, and the other parameter variables are the body height and the ground clearance. Then, according to the standard value range of other variables and the parameter variable values ​​of the problem parameter variables, the values ​​of other parameter variables can be updated, such as adjusting the body height to 1.5 meters and the ground clearance to 0.4 meters according to the problem parameter variable approach angle, and thereby generating a calibrated body model of the initial body model.

[0076] The technical solution of the embodiment of the present invention is to determine multiple groups of initial body models that meet the conditions of the whole vehicle drag coefficient; for any initial body model, determine the problem parameter variables in the initial body model that do not meet the value range judgment conditions; according to the standard value range interval corresponding to the problem parameter variables, numerically update the parameter variable values ​​of the problem parameter variables to obtain updated variable values; according to the updated variable values ​​of the problem variables, update the parameter variables other than the problem parameter variables to obtain the calibration body models of each initial body model, and determine the target body model according to the calibration body model to generate a vehicle styling rendering. The technical solution can modify the parameter variable values ​​of the body parameter variables that do not meet the standard value range interval in any initial body model until the body parameter variables of the whole vehicle meet the value range judgment conditions, and thereby generate a vehicle styling rendering that meets the requirements of the whole vehicle drag coefficient, which can more accurately and quickly realize the design of the renderings that require a low drag coefficient of the whole vehicle, so as to solve the problem of affecting the energy consumption of the whole vehicle due to the large drag coefficient of the whole vehicle.
