[0031] For the distributed electronic and electrical architecture of the automobile on the market, the automobile fuse mostly uses the traditional current fuse, mainly for overload protection function. With the rapid development of electronic and electrical architecture, the traditional current fuse has not adapted to the high efficiency and intelligent requirements of the domain controller. Among them, the Efuse chip and the high-side drive chip integrated in the domain controller are more suitable for the domain centralized electronic and electrical architecture.

[0032] However, only part of the electrical appliances are integrated in the domain controller, and most of the electrical appliances in the automobile have not realized domain integration, that is, the Efuse chip and the high-side drive chip cannot meet the demand of all electrical appliances in the automobile. Therefore, there is an urgent need for a power control method that can be used for both distributed electronic and electrical architecture and domain centralized electronic and electrical architecture, and meets the current flexible electronic and electrical architecture design.

[0033] Based on the above problems, the power supply control method provided by the application is helpful to reasonably control the power supply of various types of electrical appliances in the vehicle, and meets the current electronic and electrical architecture requirements in the vehicle.

[0035] Reference Figure 1 The vehicle can be configured with a fuse box 10, and the fuse box 10 can be provided with a first fuse 101, a second fuse 102, and a third fuse 103.

[0036] Among them, the melting heat energy value of the first fuse 101 is higher than that of the second fuse 102, and the melting heat energy value of the second fuse 102 is higher than that of the third fuse 103.

[0037] For example, the first fuse 101 can be selected to be a fuse with a melting heat energy value greater than or equal to a first melting heat energy threshold value, the second fuse 102 can be selected to be a fuse with a melting heat energy value less than the first melting heat energy threshold value and greater than or equal to a second melting heat energy threshold value, and the third fuse 103 can be selected to be a fuse with a melting heat energy value less than the second melting heat energy threshold value.

[0038] In some optional embodiments, the first fuse 101 can be used to control the power supply of the vehicle-level electrical appliance 11. The second fuse 102 can be used to control the power supply of the system-level electrical appliance 12. The third fuse 103 can be used to control the power supply of the single electrical appliance 13.

[0042] Step 201, identifying all electrical appliances in the vehicle.

[0043] Specifically, all electrical appliances in the vehicle can include vehicle-level electrical appliances, system-level electrical appliances, and single electrical appliances.

[0044] If the electrical appliance is a vehicle-level electrical appliance, step 202 is executed. Alternatively,

[0045] If the electrical appliance is a system-level electrical appliance, step 203 is performed. Alternatively,

[0046] If the electrical appliance is a single electrical appliance, step 204 is performed.

[0047] In step 202, the first fuse is used to control the power supply of the vehicle-level electrical appliance.

[0048] In some embodiments, the first fuse can be selected to have a melting heat energy threshold value greater than or equal to the first melting heat energy threshold value.

[0049] In step 203, the second fuse is used to control the power supply of the system-level electrical appliance.

[0050] In some embodiments, the second fuse can be selected to have a melting heat energy threshold value less than the first melting heat energy threshold value and greater than or equal to the second melting heat energy threshold value.

[0051] In step 204, the electrical interface requirements and electrical parameters of the single electrical appliance are obtained.

[0058] In some embodiments, the third fuse can be selected to have a melting heat energy threshold value less than the second melting heat energy threshold value.

[0059] Figure 3 The flowchart of another embodiment of the power supply control method provided in the present application can include the following steps:

[0060] In step 301, it is determined whether the single electrical appliance load is sensitive to voltage fluctuations according to the electrical interface requirements and the electrical parameters of the single electrical appliance.

[0061] Specifically, whether the single electrical appliance load is sensitive to voltage fluctuation can be determined according to the working voltage in the electrical interface requirement and the anti-interference capability in the electrical parameter.

[0062] For example, the manner of determining whether the single electrical appliance load is sensitive to voltage fluctuation can include: determining whether a sensitive value of the single electrical appliance load to voltage fluctuation is greater than a first preset threshold, wherein the sensitive value can be determined by the working voltage and the anti-interference capability.

[0063] If the sensitive value of the single electrical appliance load to voltage fluctuation is greater than the first preset threshold, it can be considered that the single electrical appliance load is sensitive to voltage fluctuation. Alternatively,

[0064] If the sensitive value of the single electrical appliance load to voltage fluctuation is less than or equal to the first preset threshold, it can be considered that the single electrical appliance load is not sensitive to voltage fluctuation.

[0065] It can be understood that the above examples are only exemplarily described by taking the working voltage and the anti-interference capability as examples, and do not constitute a limitation on the embodiments of the present application. In some embodiments, whether the load is sensitive to voltage fluctuation can also be determined by other parameters.

[0066] If the single electrical appliance load is sensitive to voltage fluctuation, step 302 is performed. Alternatively,

[0067] If the single electrical appliance load is not sensitive to voltage fluctuation, step 303 is performed.

[0068] Step 302: performing power control on the single electrical appliance by a domain controller.

[0078] The electrical appliance type can include at least a safety level.

[0079] In some optional embodiments, the electrical appliance type can further include a vibration level.

[0080] At step 405, the fuse used by the single electrical appliance is determined according to the electrical appliance type of the single electrical appliance, and the power supply of the single electrical appliance is controlled.

[0081] Specifically, the single electrical appliance can be controlled by the domain controller or the third fuse according to the electrical appliance type of the single electrical appliance.

[0083] At step 501, it is determined whether the single electrical appliance is a high-safety-factor electrical appliance according to the electrical appliance type of the single electrical appliance.

[0084] Specifically, it can be determined whether the single electrical appliance is a high-safety-factor electrical appliance according to the safety level in the electrical appliance type.

[0085] For example, it can be determined whether the single electrical appliance is a high-safety-factor electrical appliance by determining whether the safety factor of the single electrical appliance is greater than a second preset threshold.

[0086] If the safety factor of the single electrical appliance is greater than the second preset threshold, the single electrical appliance can be considered as a high-safety-factor electrical appliance. Alternatively,

[0087] If the safety factor of the single electrical appliance is less than or equal to the second preset threshold, the single electrical appliance can be considered as not a high-safety-factor electrical appliance.

[0088] It can be understood that the above example is only illustratively described by taking the safety level as an example, and does not constitute a limitation on the embodiments of the present application. In some embodiments, whether the single electrical appliance is a high-safety-factor electrical appliance can also be determined by other parameters.

[0089] If the single electrical appliance is a high-safety-factor electrical appliance, step 502 is performed. Alternatively,

[0090] If the single electrical appliance is not a high-safety-factor electrical appliance, step 503 is performed.

[0091] At step 502, the power supply of the single electrical appliance is controlled by the domain controller.

[0092] In some optional embodiments, the single electrical appliance can be controlled by the E-Fuse chip.

[0093] In step 503, the single electrical appliance is controlled by the third fuse.
