[0059] The material and shielding parameters are mainly used for analyzing the reflection, absorption and transmission of electromagnetic waves on the basis of the model of the component, so as to analyze the different characteristics of the component in different vehicle protection performances, so that the subsequent attenuation factor calculation is more accurate. The material and shielding parameters in the embodiments of the present application mainly include but are not limited to electrical conductivity, magnetic conductivity, dielectric constant, loss tangent, shielding body thickness, pore size and the like. The electrical conductivity and magnetic conductivity can be obtained by collecting the electrical conductivity and magnetic conductivity of the metal shell and shielding layer of the component; the dielectric constant can be obtained by collecting the dielectric constant of the plastic part in the component; the loss tangent can be determined according to the dielectric loss of the component; the shielding body thickness is the thickness of the shielding body or the shell of the component; and the pore size is the size, angle and depth of all pores in the component.

[0060] The electrical and radiation source parameters are mainly used for analyzing the radiation source of the component and determining the characteristics of electromagnetic radiation. The electrical and radiation source parameters in the embodiments of the present application include but are not limited to working frequency, radiation power, current amplitude and waveform, common mode current, voltage change rate, current change rate, source end and load end impedance and the like. The working frequency includes but is not limited to the fundamental frequency and harmonic frequency of electromagnetic waves in the working state of the component; the radiation power is the radiation power in the working state of the component; the current amplitude and waveform are the amplitude and corresponding waveform of the current radiation in the working state of the component; the common mode current can be collected from the common mode current on the high and low voltage wire harness of the component, which is the main radiation source of electromagnetic radiation; the voltage and current change rate are the voltage change rate and current loop change speed of the switch device contained in the component; and the source end and load end impedance are the input impedance and output impedance of the component.

[0061] The connection and wiring parameters are mainly used for more accurately analyzing the trend of the radiation source and the possible crosstalk phenomenon, helping to analyze the protection performance and different characteristics of the same component in different vehicles, so as to more accurately determine the characteristics of electromagnetic radiation. In the embodiments of the present application, the collected connection and wiring parameters mainly include but are not limited to cable type and trend, grounding mode, wire harness length and bundling density.

[0062] The whole vehicle environment parameter of the target vehicle is mainly used for more accurate analysis of electromagnetic coupling interference of the parts in the whole vehicle environment, so as to improve the accuracy of calculation in the subsequent process. The whole vehicle environment parameter in the embodiment of the application includes but is not limited to the coupling interference coefficient of the near effect, the reflection and shielding effect of the vehicle body, and the temperature parameter and the humidity parameter.

[0063] The embodiment of the application can collect various parameters of the target vehicle and the parts in the target vehicle, analyze the layout of the parts under a specific vehicle type and the different characteristics of the electromagnetic protection performance of the parts under different vehicle types through various parameters, thereby specifically decomposing the whole vehicle human body electromagnetic protection performance target of the target vehicle, improving the accuracy of decomposition of the whole vehicle human body electromagnetic protection performance target, and avoiding the situation of repeated testing and decomposition due to decomposition failure or poor effect.

[0064] In step S102, based on the multiple types of parameters, multiple decomposition coefficients corresponding to the parts of the target vehicle and human body electromagnetic protection data of the parts in multiple installation positions in the target vehicle are obtained, so as to calculate multiple protection margins of the parts in multiple installation positions in the target vehicle based on the human body electromagnetic protection data.

[0065] It can be understood by those skilled in the art in the technical field that in the process of detecting the human body electromagnetic protection target of the vehicle in the actual application scenario, the mainstream simulation software generates multiple recommended installation positions of the parts (positions with minimum electromagnetic emission) through a multi-objective optimization algorithm.

[0066] In some embodiments, after obtaining the multiple types of parameters of the target vehicle and the parts, the application can generate multiple decomposition coefficients corresponding to the parts of the target vehicle and human body electromagnetic protection data of the parts in multiple positions in the target vehicle according to the parameters.

[0067] Specifically, after obtaining the geometric and spatial parameters of the parts, the embodiment of the application can accurately simulate the model of the parts according to the geometric and spatial parameters of the parts, and input the model of the parts into the simulation software for detecting the human body electromagnetic protection target, to generate multiple installation positions suitable for the installation of the parts and the human body electromagnetic protection data corresponding to the installation positions, i.e. the human body electromagnetic protection data of the parts in multiple positions in the target vehicle.

[0068] Further, the embodiment of the application can also calculate multiple protection margins of the parts in multiple installation positions in the target vehicle based on the human body electromagnetic protection data. The protection margin here can be understood as the difference between the human body electromagnetic protection performance target limit value of the parts and the actual human body electromagnetic protection performance of the parts in each installation position. The human body electromagnetic protection performance target limit value of the parts here can be but is not limited to the reference value in the human body electromagnetic protection performance execution standard.

[0071] The embodiment of the present application can calculate a plurality of decomposition coefficients of the parts and a protection margin of human body electromagnetic protection data of the parts in a plurality of installation positions of the target vehicle, so as to guarantee that the target vehicle human body electromagnetic protection performance target is decomposed in full consideration of the electromagnetic influencing factors of the parts, and effectively improve the effectiveness and accuracy of the decomposition of the target vehicle human body electromagnetic protection performance target.

[0072] In step S103, a plurality of attenuation factors of the parts are calculated respectively according to the plurality of decomposition coefficients and the plurality of protection margins, so as to decompose the target vehicle human body electromagnetic protection performance target based on the plurality of attenuation factors, and generate at least one human body electromagnetic protection performance target of the parts. The calculation formula of the plurality of attenuation factors can be but is not limited to represented as:

[0073]

[0074]

[0075]

[0076] wherein, is the attenuation factor of the part, is the protection margin of the part after the vehicle layout analysis, , , , is the protection margin of the part after the vehicle layout analysis, , , , is the human body electromagnetic protection data of the part in the four installation positions, , , , is the human body electromagnetic protection data of the part in the four installation positions, is the electromagnetic radiation absorption coefficient, is the electromagnetic radiation reflection correction coefficient, A reflection correction coefficient of electromagnetic radiation, A reflection correction coefficient of the vehicle body.

[0077] The decomposition formula of the whole vehicle human electromagnetic protection performance target can be, but is not limited to, expressed as:

[0078]

[0079]

[0080]

[0081] Wherein, is the human electromagnetic protection performance target of the part after decomposition, is the whole vehicle human electromagnetic protection performance target, is the attenuation factor of the part.

[0082] As a possible implementation manner, after obtaining the multiple decomposition coefficients corresponding to the part and the multiple protection margins of the part in the multiple installation positions of the target vehicle, the multiple attenuation factors of the part can be calculated by combining the two, so as to decompose the whole vehicle human electromagnetic protection performance target according to the attenuation factors, and obtain at least one human electromagnetic protection performance target of the part.

[0083] For example, on the basis of the simulation software generating the multiple installation positions of a part , the human electromagnetic protection data of the part in the four installation positions can be obtained , , , respectively. Taking the human electromagnetic protection performance target limit value of the part as , the multiple protection margins of the part in the four installation positions can be, but are not limited to, expressed as:

[0084]

[0085]

[0086]

[0087]

[0088] Wherein, is the protection margin of the part in the whole vehicle layout analysis , , , .

[0089] On this basis, the attenuation factor of the component can be but not limited to expressed as:

[0091]

[0092]

[0093] wherein, is the attenuation factor of the component, is the electromagnetic radiation absorption coefficient, is the electromagnetic radiation reflection correction coefficient, is the electromagnetic radiation reflection correction coefficient, is the vehicle body reflection correction coefficient.

[0094] Finally, the human body electromagnetic protection performance target of the component can be but not limited to expressed as follows:

[0095]

[0096]

[0097]

[0098] wherein, is the human body electromagnetic protection performance target of the component after decomposition, is the whole vehicle human body electromagnetic protection target.

[0099] According to the human body electromagnetic protection performance target of the component, the decomposition value a hierarchical target conforming to the layout of the component can be set, is the first level component human body protection performance target, is the second level component human body protection performance target, is the third level component human body protection performance target, thereby completing the decomposition process of the whole vehicle human body electromagnetic protection performance target to the component human body electromagnetic protection performance target.

[0100] The embodiment of the present application can consider the layout of the component under a specific vehicle model and the different characteristics of the electromagnetic protection performance of the component under different vehicle models to decompose the whole vehicle human body electromagnetic protection performance target, realize the decomposition of the whole vehicle human body electromagnetic protection performance target to the component human body electromagnetic protection performance target, and effectively guarantee the pertinence and accuracy of the human body electromagnetic protection performance target of the component obtained by decomposition with respect to the target vehicle, which can greatly reduce the test and rectification time of the component index in the confirmation stage and improve the operation efficiency of the component index confirmation stage.

[0101] Optionally, in an embodiment of the present application, after obtaining the at least one human electromagnetic protection performance target of the component, further comprising: obtaining an electromagnetic interference amount between the component and the target vehicle and / or other components in the target vehicle except the component; and determining the final human electromagnetic protection performance target of the component in combination with the plurality of protection margins, the electromagnetic interference amount and the at least one human electromagnetic protection performance target.

[0102] In other embodiments, considering that in actual application scenarios, the actual human electromagnetic protection performance data of the component not only needs to consider the difference between the human electromagnetic protection performance target limit value, i.e., the protection margin, but also needs to consider whether it will be interfered by the magnetic field of the in-vehicle environment of the target vehicle or other components in the actual installation process. Therefore, the embodiment of the present application can also obtain an electromagnetic interference amount (the magnetic field interference strength of other components on the component) between the component and the target vehicle and / or other components in the target vehicle except the component (the target vehicle or other components or the target vehicle and other components), so as to determine the final human electromagnetic protection performance target of the component in combination with the plurality of protection margins, the electromagnetic interference amount and the at least one human electromagnetic protection performance target.

[0103] That is, the embodiment of the present application can select the final human electromagnetic protection performance target of the component from the decomposed human electromagnetic protection performance targets of the component according to the protection margin of the component and the electromagnetic interference amount between the component and the target vehicle and / or other components.

[0104] For example, after obtaining the human electromagnetic protection performance target of the component, the protection margin of a certain human electromagnetic protection performance target is relatively high, but the electromagnetic interference of other components on the component based on the human electromagnetic protection performance target (the installation position corresponding to the human electromagnetic protection performance target) is relatively strong, and the final human electromagnetic protection performance target that the component can achieve in the first case is obtained by comprehensively considering the two; the protection margin of another human electromagnetic protection performance target is relatively low, but the electromagnetic interference of other components on the component based on the human electromagnetic protection performance target is relatively low, and the final human electromagnetic protection performance target that the component can achieve in the second case is obtained by comprehensively considering the two; by comparing the two, the human electromagnetic protection performance target in the first case is lower than the human electromagnetic protection performance target in the second case, and at this time, the human electromagnetic protection performance target in the first case can be selected.

[0105] The embodiment of the present application can give the human electromagnetic protection performance target of the component in multiple levels, and then consider the electromagnetic interference amount of other components on the component in different installation positions corresponding to each human electromagnetic protection performance target of the component, and comprehensively determine the final human electromagnetic protection performance target of the component, so as to effectively select the most suitable human electromagnetic protection performance target of the component.

[0120] The decomposition module 300 is configured to calculate a plurality of attenuation factors of the parts respectively based on the plurality of decomposition coefficients and the plurality of protection margins, so as to decompose a whole vehicle human electromagnetic protection performance target based on the plurality of attenuation factors and generate at least one human electromagnetic protection performance target of the parts.

[0121] Optionally, in an embodiment of the present application, the analysis module 100 comprises an acquisition unit and a determination unit.

[0137] It should be noted that the aforementioned explanation and description of the embodiment of the whole vehicle to part human electromagnetic protection performance target decomposition method also applies to the whole vehicle to part human electromagnetic protection performance target decomposition device 10 of this embodiment, which will not be described here again.

[0138] According to the vehicle-to-component electromagnetic shielding performance target decomposition device 10 proposed in this application, multiple decomposition coefficients corresponding to the components of the target vehicle and multiple protection margins of the components at multiple installation positions in the target vehicle can be obtained according to multiple parameters of the components. Finally, multiple attenuation factors of the components are calculated to decompose the vehicle's electromagnetic shielding performance target, resulting in at least one electromagnetic shielding performance target for the component. This achieves the acquisition of multiple parameters related to the electromagnetic shielding of components based on the layout of components under a specific vehicle model and the different characteristics of the electromagnetic shielding performance of components under different vehicle models. This ensures the pertinence and effectiveness of the vehicle's electromagnetic shielding performance target decomposition. Furthermore, by obtaining decomposition coefficients related to the electromagnetic shielding of components based on multiple parameters of the components and calculating attenuation factors for decomposing the vehicle's electromagnetic shielding performance target, it is possible to achieve the vehicle electromagnetic shielding performance target decomposition for a specific vehicle model. This provides engineers with an efficient and accurate approach and method for vehicle electromagnetic shielding target decomposition, helping vehicle manufacturers to quickly decompose the corresponding targets to relevant components after vehicle electromagnetic shielding testing, saving time in confirming component indicators. This solves the problems in related technologies where the electromagnetic protection target of the whole vehicle is decomposed into individual components based on experience, which ignores the layout of components under specific vehicle models and the different electromagnetic protection performance of components under different vehicle models. This results in the decomposition of performance targets lacking specificity and accuracy, and even leads to the failure of target decomposition or poor results, requiring repeated testing and decomposition, making it difficult to meet the needs of decomposing electromagnetic protection targets for the whole vehicle.
