[0030] Embodiment 1

[0031] Figure 1 A flowchart of a method for generating a vehicle styling effect diagram is provided for Embodiment 1 of the present invention. This embodiment is applicable to the process of designing and selecting the overall vehicle styling. To avoid the situation where the vehicle energy consumption is affected due to a large overall vehicle drag coefficient, this method can be executed by a vehicle styling effect diagram generation device, which can be implemented in the form of hardware and / or software, and the vehicle styling effect diagram generation device can be configured in an electronic device. As Figure 1 shown, the method includes:

[0032] S110. Determine multiple groups of initial vehicle body models that meet the overall vehicle drag coefficient condition; each initial vehicle body model corresponds to a parameter variable value of its own parameter variable of the overall vehicle body parameters.

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

[0034] Among them, the vehicle aerodynamic drag coefficient condition can be a condition for designing the vehicle body model with the goal of minimizing the vehicle aerodynamic drag coefficient.

[0035] Among them, the initial vehicle body model can be a vehicle body model generated from the vehicle body parameter variables of the whole vehicle obtained according to the goal of minimizing the vehicle aerodynamic drag coefficient. Among them, the vehicle body parameter variables of the whole vehicle can be vehicle variables and body variables set according to preset conditions, specifically vehicle variables and body variables set according to dimensions such as styling aesthetics, space size, and human-machine comfort. Exemplarily, the vehicle body parameter variables of the whole vehicle can be automatically generated according to the requirements of preset conditions.

[0036] Specifically, with the goal of the minimum aerodynamic drag coefficient, the parameter variable values of the vehicle body parameter variables of the whole vehicle are determined, and then an initial vehicle body model is generated according to the determined parameter variable values of the vehicle body parameter variables of the whole vehicle. Exemplarily, with the goal of the minimum aerodynamic drag coefficient, through a vehicle body model generation device, the vehicle variables and body variables are automatically set, and a corresponding initial vehicle body model is generated. This embodiment does not make specific limitations on this.

[0037] S120. According to the standard value range interval corresponding to the vehicle body parameter variables of the whole vehicle, adjust the parameter variable values of the vehicle body parameter variables of each initial vehicle body model to generate a calibrated vehicle body model corresponding to each initial vehicle body model.

[0038] Among them, the standard value range interval can be the value range of the parameter variable values of the vehicle body parameter variables of the whole vehicle when conducting vehicle styling design. Exemplarily, the standard value range interval of the approach angle can be between 15° and 25°.

[0039] Among them, the calibrated vehicle body model can be a vehicle body model generated after adjusting the vehicle body parameter variables of the whole vehicle with body parameter variables that are not within the standard value interval according to the standard value range interval.

[0040] It should be noted that since the parameter variable values of the vehicle body parameter variables of the initial vehicle body model are generated with the goal of the minimum aerodynamic drag coefficient, therefore, in the generation result to meet the optimal goal, there may be some parameter variable values of the vehicle body parameter variables of the whole vehicle that are not within their own standard value range intervals. Therefore, it is necessary to make an adaptive adjustment to the parameter variable values that are not within the standard interval range. And due to the interaction and influence between different vehicle body parameter variables of the whole vehicle, when changing the parameter variable value of any vehicle body parameter variable of the whole vehicle, the parameter variable values of other vehicle body parameter variables of the whole vehicle also need to be adaptively adjusted according to their interaction relationship and influence to ensure that the interaction relationship between the parameter variables is not changed.

[0041] Exemplarily, continuing with the above example, if the approach angle in the initial vehicle body model is obtained as 10° (the parameter variable value is not within its standard value range of 15° to 25°), then it is necessary to adjust the parameter variable value of the approach angle and adaptively adjust the parameter variable values of other vehicle body parameter variables of the entire vehicle to obtain the adjusted parameter variable values of the vehicle body parameter variables of the entire vehicle. Furthermore, based on the adjusted parameter variable values of the vehicle body parameter variables of the entire vehicle, a calibrated vehicle body model corresponding to the initial vehicle body model is generated.

[0042] S130. Determine the target vehicle body model according to the parameter variable values of the vehicle body parameter variables of each calibrated vehicle body model.

[0043] Exemplarily, the determined vehicle body model that meets the preset conditions can 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 of the entire vehicle. Furthermore, based on the calculated aerodynamic drag value, the target vehicle body model is determined.

[0044] Optionally, determining the target vehicle body model according to the parameter variable values of the vehicle body parameter variables of each calibrated vehicle body model includes: determining the aerodynamic drag value corresponding to each calibrated vehicle body model according to the parameter variable values of the vehicle body parameter variables of each calibrated vehicle body model; determining the target vehicle body model according to the aerodynamic drag values corresponding to each calibrated vehicle body model.

[0045] Among them, the aerodynamic drag value can be the air resistance value during the driving of the vehicle body of the entire vehicle. Among them, the calculation method can be pre-set by relevant technical personnel according to experience. For example, it can be to perform simulation calculations using numerical wind tunnel software. This embodiment does not make specific limitations on this.

[0046] Specifically, the aerodynamic drag value results of each calibrated vehicle body model can be calculated respectively according to the parameter variable values of the vehicle body parameter variables corresponding to each calibrated vehicle body model. Furthermore, the target vehicle 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 each calibrated vehicle body model includes: determining the calibrated vehicle body model with the smallest aerodynamic drag value as the target vehicle body model.

[0048] Specifically, in order to better fit the actual vehicle usage scenarios, the calibrated vehicle body model with the minimum aerodynamic drag value can be determined as the target vehicle body model according to the calculated aerodynamic drag value results corresponding to each calibrated vehicle body model. Exemplarily, if there are calibrated vehicle body model a, calibrated vehicle body model b, and calibrated vehicle body model c, and the calculated aerodynamic drag value of calibrated vehicle body model a is 0.2, the aerodynamic drag value of calibrated vehicle body model b is 0.5, and the aerodynamic drag value of calibrated vehicle body model c is 0.3, then according to the calculated aerodynamic drag value results, among calibrated vehicle body model a, calibrated vehicle body model b, and calibrated vehicle body model c, the calibrated vehicle body model with the minimum aerodynamic drag value result can be determined as the target vehicle body model. Specifically, since the aerodynamic drag value result of calibrated vehicle body model a is the minimum at 0.2, calibrated vehicle body model a can be determined as the target vehicle 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, determining the target vehicle body model according to the aerodynamic drag values respectively corresponding to each calibrated vehicle body model includes: selecting at least one reference vehicle body model according to the aerodynamic drag values respectively corresponding to each calibrated vehicle body model; and determining the target vehicle body model according to the parameter variable values of the vehicle body parameter variables of each reference vehicle body model.

[0051] Exemplarily, if there are calibrated vehicle body model d, calibrated vehicle body model e, and calibrated vehicle body model f, and the calculated aerodynamic drag value of calibrated vehicle body model d is 0.3, the aerodynamic drag value of calibrated vehicle body model e is 0.5, and the aerodynamic drag value of calibrated vehicle body model f is 0.3, then according to the calculated aerodynamic drag value results, calibrated vehicle body model d and calibrated vehicle body model f can be used as the reference vehicle body models.

[0052] Specifically, determining the target vehicle body model according to the parameter variable values of the vehicle body parameter variables of each reference vehicle body model can be to obtain the parameter variable values of the vehicle body parameter variables of at least one selected reference vehicle body model, and determine the target vehicle body model according to dimensions such as styling aesthetics, space size, and human-machine comfort. Continuing with the above example, if the reference vehicle body models are calibrated vehicle body model d and calibrated vehicle body model f, obtain the parameter variable values of the vehicle body parameter variables of each reference vehicle body model. Among them, the length of the cab of calibrated vehicle 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 calibrated vehicle body model f 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 calibrated vehicle body model d is superior to calibrated vehicle body model f in terms of dimensions such as space size and human-machine interaction. Therefore, calibrated vehicle body model d can be determined as the target vehicle body model.

[0053] S140. Generate a vehicle styling effect drawing based on the parameter variable values of the vehicle body parameters of the target vehicle body model.

[0054] Among them, the vehicle styling effect drawing can be the final vehicle styling design drawing generated based on the parameter variable values of the vehicle body parameters corresponding to the target vehicle body model.

[0055] In the technical solution of the embodiment of the present invention, multiple groups of initial vehicle body models are determined under the condition of meeting the vehicle wind resistance coefficient; according to the standard value range interval corresponding to the vehicle body parameter variables of the whole vehicle, the parameter variable values of the vehicle body parameter variables of each initial vehicle body model are adjusted to generate calibrated vehicle body models corresponding to each initial vehicle body model respectively; according to the parameter variable values of the vehicle body parameter variables of each calibrated vehicle body model, a target vehicle body model is determined; and a vehicle styling effect drawing is generated based on the parameter variable values of the vehicle body parameter variables of the target vehicle body model. This technical solution can generate a vehicle body model by determining the corresponding vehicle body parameter variables that meet the vehicle wind resistance coefficient condition; by combining the vehicle wind resistance coefficient condition and the vehicle body parameter variables of the whole vehicle, it realizes the design of the vehicle styling effect drawing with a low vehicle wind resistance coefficient, and solves the problem that the vehicle energy consumption is affected due to the large vehicle wind resistance coefficient.

[0056] Embodiment Two

[0057] Figure 2 It is a flowchart of a method for generating a vehicle styling effect drawing provided by the second embodiment of the present invention. Figure 2 It is a flowchart of a method for generating a vehicle styling effect drawing provided by the second embodiment of the present invention. On the basis of the above embodiment, the above method for generating a vehicle styling effect drawing is further optimized.

[0058] Further, the step of "according to the standard value range interval corresponding to the vehicle body parameter variables of the whole vehicle, adjusting the parameter variable values of the vehicle body parameter variables of each initial vehicle body model to generate calibrated vehicle body models corresponding to each initial vehicle body model respectively" is refined to "for any initial vehicle body model, based on the standard value range interval corresponding to the vehicle body parameter variables of the whole vehicle, determine the problem parameter variables in the initial vehicle body model that do not meet the value range judgment condition according to the parameter variable values of the vehicle body parameter variables of the initial vehicle body model; update the parameter variable values of the problem parameter variables according to the standard value range interval corresponding to the problem parameter variables to obtain updated variable values; adjust the parameter variable values of other parameter variables according to the updated variable values of the problem parameter variables until all the vehicle body parameter variables meet the value range judgment condition to obtain the calibrated vehicle body model of the initial vehicle body model; other parameter variables are the parameter variables of the vehicle body parameter variables of the whole vehicle except the problem parameter variables" to improve the vehicle styling effect drawing generation method. As Figure 2 shown, the method includes:

[0059] S210. Determine multiple groups of initial vehicle body models that meet the vehicle aerodynamic drag coefficient condition; each initial vehicle body model corresponds to the parameter variable values of its own vehicle body parameter variables.

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

[0061] Among them, the value range judgment condition can be used to determine whether the vehicle body parameter variables are within the corresponding standard value range interval. The problem parameter variables can be the vehicle body parameter variables that are not within the standard value range among the vehicle body parameter variables.

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

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

[0064] S230. 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.

[0065] Specifically, according to the standard value range interval corresponding to the problem parameter variables, the parameter variable values of the problem parameter variables can be adjusted to within the corresponding standard value range interval, and thus the adjusted parameter variable values are determined as the updated variable values.

[0066] Continuing the above example, if the body height of the obtained initial vehicle body model is 2 meters, and its corresponding standard value range can be from 0.8 meters to 1.5 meters, then the body height of this initial vehicle body model can be adjusted to 1.5 meters. And update the body height value of this initial vehicle body model according to the adjusted body height value to obtain the updated body height value.

[0067] S240. Adjust the parameter variable values of other parameter variables according to the updated variable value of the problem parameter variable until all the vehicle body parameter variables of the initial vehicle body model meet the value range judgment conditions, and obtain the calibrated vehicle body model of the initial vehicle body model; wherein, the other parameter variables are the parameter variables other than the problem parameter variable among the vehicle body parameter variables of the whole vehicle.

[0068] Due to the specific correlations among the vehicle body parameter variables of the whole vehicle, when adjusting any vehicle body parameter variable of the whole vehicle, the other parameter variables also need to be adjusted adaptively accordingly. Continuing with the above example, the vehicle body height of the initial vehicle body model is adjusted from 2 meters to 1.5 meters, and the updated variable value of the vehicle body height of the initial vehicle body model is obtained as 1.5 meters. Furthermore, according to the obtained updated variable value of the vehicle body height of the initial vehicle body model, the ground clearance and cab height of the initial vehicle body model are adjusted accordingly. It should be noted that the way to adjust the parameter variable values of other parameter variables can be manual adjustment or automatic adjustment according to the corresponding relationship between the variables. Iteratively adjust until all the vehicle body parameter variables of the initial vehicle body model meet the value range judgment conditions, and generate the calibrated vehicle body model of the initial vehicle body model in this way.

[0069] S250. Determine the target vehicle body model according to the parameter variable values of the vehicle body parameter variables of each calibrated vehicle body model.

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

[0071] In an alternative solution of this embodiment, it can be combined with one or more alternative solutions in this embodiment. Optionally, according to the standard value range interval corresponding to the vehicle body parameter variables of the whole vehicle, adjust the parameter variable values of the vehicle body parameter variables of each initial vehicle body model to generate the calibrated vehicle body model corresponding to each initial vehicle body model, including: for any initial vehicle body model, based on the standard value range interval corresponding to the vehicle body parameter variables of the whole vehicle, determine the problem parameter variable that does not meet the value range judgment conditions in this initial vehicle body model according to the parameter variable values of the vehicle body parameter variables of this initial vehicle body model; update the numerical values of the parameter variable values of other parameter variables according to the standard value range interval corresponding to the other parameter variables to obtain the updated variable value; the other parameter variables are the parameter variables other than the problem parameter variable among the vehicle body parameter variables of the whole vehicle; adjust the parameter variable values of the problem parameter variable according to the updated variable values of the other parameter variables until all the vehicle body parameter variables meet the value range judgment conditions, and obtain the calibrated vehicle body model of this initial vehicle body model.

[0072] Exemplarily, 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 from 15° to 25°, the standard value range of the vehicle body height can be from 0.8 meters to 1.7 meters, and the standard value range of the ground clearance can be from 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 vehicle body model is the approach angle, and the other parameter variables are the vehicle body height and the ground clearance.

[0073] Furthermore, according to the standard value ranges of the other variables, the other parameter variables can be adjusted. For example, the vehicle body 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 influence between the vehicle body parameter variables of the whole vehicle, the approach angle can be adjusted to 22°, so that all the vehicle body parameter variables of the whole vehicle meet the value range judgment condition, and a calibrated vehicle body model of the initial vehicle body model can be generated accordingly.

[0074] In another alternative solution of this embodiment, it can be combined with one or more alternative solutions in this embodiment. Optionally, according to the standard value range intervals corresponding to the vehicle body parameter variables of the whole vehicle, the parameter variable values of the vehicle body parameter variables of each initial vehicle body model are adjusted to generate the calibrated vehicle body models respectively corresponding to each initial vehicle body model, including: for any initial vehicle body model, based on the parameter variable values of the vehicle body parameter variables of this initial vehicle body model and the standard value range intervals corresponding to the vehicle body parameter variables of the whole vehicle, determine the problem parameter variable that does not meet the value range judgment condition in this initial vehicle body model and the corresponding parameter variable value; according to the standard value range intervals corresponding to the other parameter variables, numerically update the parameter variable values of the other parameter variables to obtain updated variable values adapted to the parameter variable values of the problem parameter variable; the other parameter variables are the parameter variables other than the problem parameter variable among the vehicle body parameter variables of the whole vehicle; according to the updated variable values of the other parameter variables and the parameter variable values of the problem parameter variable, obtain the calibrated vehicle body model of this initial vehicle body model.

[0075] Exemplarily, if the approach angle of the initial vehicle body model is 13°, the vehicle body height is 1 m, and the ground clearance is 0.25 m, where the standard value range of the approach angle can be from 15° to 25°, the standard value range of the vehicle body height can be from 0.8 m to 1.7 m, and the standard value range of the ground clearance can be from 0.2 m to 0.4 m, then it can be determined that the problem 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. Furthermore, according to the standard value ranges of the other variables and the parameter variable value of the problem parameter variable, the parameter variable values of the other parameter variables can be updated. For example, according to the problem parameter variable of the approach angle, the vehicle body height can be adjusted to 1.5 m, and the ground clearance can be adjusted to 0.4 m, and the calibrated vehicle body model of the initial vehicle body model can be generated accordingly.

[0076] The technical solution of the embodiment of the present invention determines multiple groups of initial vehicle body models that meet the vehicle aerodynamic drag coefficient condition; for any initial vehicle body model, determines the problem parameter variable that does not meet the value range judgment condition in the initial vehicle body model; numerically updates the parameter variable value of the problem parameter variable according to the corresponding standard value range interval of the problem parameter variable to obtain the updated variable value; updates the parameter variables other than the problem parameter variable according to the updated variable value of the problem variable to obtain the calibrated vehicle body model of each initial vehicle body model, and determines the target vehicle body model according to the calibrated vehicle body model to generate the vehicle styling effect drawing. This technical solution can modify the parameter variable values of the vehicle body parameter variables that do not meet the standard value range interval in any initial vehicle body model until all the vehicle body parameter variables meet the value range judgment condition, and generate the vehicle styling effect drawing that meets the vehicle aerodynamic drag coefficient requirement accordingly, which can more accurately and quickly realize the design of the effect drawing that meets the low vehicle aerodynamic drag coefficient requirement to solve the problem that the vehicle energy consumption is affected due to the large vehicle aerodynamic drag coefficient.
