[0045] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present invention and are not used to limit the present invention.

[0046] In order to better understand the technical solution of the present invention, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0047] The main solution of the embodiment of the present invention is: obtaining the functional type of each electronic controller in the electronic controller set of power management; dividing each electronic controller in the electronic controller set into corresponding local functional groups according to the functional type; connecting each local functional group to a corresponding low-voltage power supply; and supplying power to the corresponding local functional group through the low-voltage power supply.

[0048] In this embodiment, for the convenience of description, the following description is made by taking the identification of the power supply controller as the execution subject.

[0049] In the prior art, if there is only one regional point to manage the electronic controller for the low-voltage battery of the whole vehicle, it may cause the low-voltage battery of the whole vehicle to be overpowered, that is, a certain ECU will have a large static current consumption due to its own fault, which will cause all low-voltage controllers of the whole vehicle to fail to work.

[0050] The present invention provides a solution, by dividing all electronic controllers involved in low-voltage power management according to functional areas, and dividing the areas according to the functions of the electronic controllers, regional power management is implemented on the whole vehicle, the nodes involved in power management can be divided into multiple local functional groups, and the low-voltage power supplies involved in power supply work independently of each other without affecting each other, therefore, once a power-off signal fed back by the low-voltage power supply is received, the faulty electronic controller can be quickly located. Compared with the prior art, the present invention will not cause all low-voltage controllers of the whole vehicle to fail to work even if the static current consumption of a certain electronic controller is large due to its own fault.

[0051] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, etc. The power controller is taken as an example to illustrate this embodiment and the following embodiments.

[0052] Based on this, an embodiment of the present invention provides a power management method, referring to Figure 1 , Figure 1 A flowchart diagram of the first embodiment of the power management method of the present invention is provided.

[0053] In this embodiment, the power management method includes steps S10 to S40:

[0054] Step S10, obtaining the function type of each electronic controller in the electronic controller set for power management.

[0055] It should be noted that the electronic controller may be a Bluetooth key DKM, or a left vehicle body domain controller VIUL, etc., which is not limited in this embodiment;

[0056] It should be noted that the above-mentioned function type may be a vehicle unlocking function or a vehicle equipment low voltage to high voltage conversion function, etc., and this embodiment does not limit this.

[0057] It is understandable that in different power management schemes, the electronic controller and the functional types are different.

[0058] In a specific implementation, there are a large number of electronic controller sets involved in power management, and the functions performed by each electronic controller are also different. Some electronic controllers can complete tasks independently, while some electronic controllers need to cooperate with other electronic controllers to complete tasks. Therefore, it is necessary to first obtain the function type of each electronic controller in the set of electronic controllers involved in power management in the entire vehicle.

[0059] Step S20: dividing each of the electronic controllers in the electronic controller set into corresponding local functional groups according to the functional type.

[0060] It should be noted that the above-mentioned local functional group may be an active local functional group or a passive local functional group, etc., and this embodiment does not limit this.

[0061] It is understandable that in different power management schemes, the local function groups are different.

[0062] In a specific implementation, the various electronic controllers in the electronic controller set are divided according to the above-mentioned functional types, and the above-mentioned resistance controllers related to the functional types are divided into the same above-mentioned local functional group. It should be noted that the number of the above-mentioned local functional groups is related to the actual above-mentioned functional types.

[0063] Step S30, connecting each of the local functional groups to a corresponding low-voltage power supply.

[0064] It should be noted that the above-mentioned low-voltage power supply can be a battery.

[0065] It is understandable that in different power management schemes, the quantity and capacity of the low-voltage power supplies are different.

[0066] In a specific implementation, the storage battery in the vehicle is divided into a plurality of the above-mentioned low-voltage power supplies corresponding to the number of the above-mentioned local functional groups by means of slicing, and the above-mentioned local functional groups are connected to the corresponding above-mentioned low-voltage power supplies.

[0067] Step S40: supplying power to the corresponding local functional group through the low voltage power supply.

[0068] In a specific implementation, when it is detected that the vehicle needs to perform work on a certain module, the corresponding local functional group is powered by the low-voltage power supply. If there is an abnormal electronic controller in the local functional group, the low-voltage power supply feedback power-off signal is received. At this time, the faulty electronic controller can be quickly located according to the low-voltage power supply that feedbacks the power-off signal. This embodiment provides a power management method, which obtains the functional type of each electronic controller in the electronic controller set managed by the power supply; divides each electronic controller in the electronic controller set into corresponding local functional groups according to the functional type; connects each local functional group to a corresponding low-voltage power supply; and powers the corresponding local functional group through the low-voltage power supply. Therefore, compared with the prior art, the present invention will not cause all low-voltage controllers of the vehicle to fail to work even if a certain electronic controller has a large static current consumption due to its own fault.

[0069] Based on the first embodiment of the present invention, in the second embodiment of the present invention, the same or similar contents as those in the first embodiment can refer to the above introduction, and will not be repeated in the following.

[0091] It should be noted that the above power consumption may be the power consumption of the above local functional group in all states.

[0092] It is understandable that the power consumption is different in different power management schemes.
