This trend has not only profoundly changed the driving experience and functional positioning of automobiles, but also put forward more stringent requirements on their electrical systems. In this context, the number of electrical devices integrated into vehicles has increased dramatically, from basic lighting and audio systems to advanced driver assistance systems (ADAS), in-vehicle entertainment systems, automatic driving controllers and even electric drive systems. The integration of each technology is accompanied by a significant increase in power demand. These devices are not only diverse, but also the power required for their operation is constantly increasing to meet increasingly complex functional requirements and high performance.

[0003] However, as a whole, the internal space layout and energy management of the vehicle face severe challenges. It is necessary to ensure the comfort and safety of passengers, and provide enough installation space for the increasing number of electrical equipment. More importantly, in the era of electric vehicles that pursue high efficiency and long battery life, energy consumption management has become one of the key factors that determine vehicle performance and market competitiveness. Therefore, how to reasonably allocate and efficiently utilize each power supply resource under limited energy supply has become a major issue that automakers must face.

[0062] The following specific implementations are used to explain the technical solutions of the claims of the present invention so that those skilled in the art can understand the claims. The protection scope of the present invention is not limited to the following specific implementation structures. The technical solutions of the claims of the present invention made by those skilled in the art but different from the following specific implementations are also within the protection scope of the present invention.

[0063] Example 1

[0064] Step 1: Divide the working hours of the electrical equipment corresponding to each insurance specification;

[0065] After the insurance specifications of all electrical equipment in the vehicle are selected, the working hours of the electrical equipment corresponding to each insurance specification are divided respectively. The principles of dividing the working hours include:

[0066] 1) If two or more electrical devices have unavoidable synchronous operation, these electrical devices are divided into the same working period;

[0067] 2) If there is no possibility for two or more electrical devices to work synchronously, these electrical devices are divided into different working periods;

[0068] 3) If two or more electrical devices may work synchronously, but can be prohibited from working simultaneously through control strategies, and such control strategies will not cause user complaints, then these electrical devices should be divided into different working periods;

[0069] 4) For a certain electrical device, it may be possible to work synchronously with multiple other electrical devices, so the device is divided into multiple working periods.

[0070] Table 1 below is an example of the division of working time periods for electrical equipment. The division of working time periods shown in this table is only one of them. These working time division methods are built into the intelligent power distribution device and can be edited online through external mobile phones, computers and other portable devices, or the division results completed offline can be directly received.

[0071] Table 1 Division of working hours of electrical equipment

[0072]

[0073] Step 2: Allocate the power supply resources of the whole vehicle according to the divided working hours;

[0074] After completing the division of working periods for all electrical equipment in the vehicle, the power supply resources of the vehicle can be allocated. The allocation of power supply resources for the vehicle is automatically completed after the intelligent power distribution device receives the result of the division of working periods of the vehicle equipment completed in step 1.

[0075] The vehicle power supply resource allocation principle is built into the intelligent power distribution device, which can be edited, modified and updated. Taking the fuse box in the power supply resource as an example, after matching the time period and fuse specifications of the power-consuming equipment, the matched output list is input into the intelligent fuse box. The intelligent fuse box combines the list and the power supply resources of the fuse box to complete the power supply resource allocation. After the output hole position and the corresponding relationship between the power-consuming equipment are allocated, the wiring diagram of the intelligent fuse box is obtained.

[0076] The power supply resources described in the present invention include various resources such as fuses of various specifications, MOS tubes, and codable protection devices, wherein the principles of vehicle insurance resource allocation include:

[0077] 1) Electrical equipment that works all the time cannot share insurance resources with other electrical equipment;

[0078] 2) The electrical equipment related to vehicle driving safety is powered independently. The equipment related to safety is distinguished and defined through the working period definition. At the same time, a preset list of safety-related electrical equipment is stored in the intelligent power distribution device to verify the work division results of the electrical equipment;

[0079] 3) Electric equipment with the same insurance specifications and in the same working hours are prohibited from sharing insurance resources;

[0080] 4) Electrical equipment with different insurance specifications are prohibited from sharing insurance resources.

[0081] Step 3: Formulate a vehicle power supply strategy based on the divided working hours;

[0082] In order to optimize the configuration of vehicle power supply resources and improve the utilization efficiency of vehicle power supply resources, it is necessary to analyze and formulate the power supply controller strategy for each power-consuming device. When formulating the power-consuming device control strategy, the following principles need to be followed:

[0083] 1) For electrical equipment that does not work full-time, follow the principle of not causing user complaints and use the mutual exclusion principle to prohibit electrical equipment from working at the same time; that is, only one electrical equipment that does not work full-time can be turned on at the same time.

[0084] 2) Set power priorities for each power-consuming device that shares a power source, and manage power supply according to the priority. Devices with lower priorities can only work when devices with higher priorities are not working. A set of power-consuming device priorities should be built into the intelligent power distribution device to guide the vehicle power distribution device to distribute power.

[0085] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.

[0086] The following uses the example of a 12V power socket and a speaker sharing a power supply to describe an embodiment of a vehicle power supply strategy of the present invention:

[0087] The control principle diagram of the 12V power socket and the speaker sharing the power supply is as follows Figure 2 As shown, the speaker and 12V power socket are connected to the two output ends of a five-pin relay respectively: the 12V power socket is connected to the normally closed contact of the relay, the speaker is connected to the normally open contact of the relay, and the speaker switch is connected to the coil end of the relay. When the speaker switch is closed, the relay coil is energized. The control logic is as follows:

[0088] When the horn switch is pressed, the horn relay coil is energized, the relay operates, and switches from the normally closed contact to the normally open contact, turning on the horn power supply and simultaneously disconnecting the power supply of the 12V power socket connected to the normally closed contact of the relay.

[0089] This control strategy avoids the 12V power socket and the speaker from working at the same time, thus achieving the purpose of the speaker and the 12V power socket sharing power.

[0090] The following describes an embodiment of the vehicle power supply strategy for one of the multi-electric devices of the present invention, taking the shared power supply of the rear defrost, electric pedal, and left front door glass lift motor as an example:

[0091] First, determine the working priorities of the three electrical devices: rear defrost, electric pedal, and left front door glass lift motor. The working priorities are as follows:

[0092] Window lift motor > rear defrost > electric pedal

[0093] The priorities of power-consuming equipment are preset in the intelligent power distribution device for use by the intelligent power distribution device when distributing power.

[0094] The rear defrost, electric pedal, and left front door glass lift motor share a common power supply control schematic diagram as shown below: Figure 3 As shown, each electrical device has a control relay. According to the working priority, the electrical device with a lower priority is connected to the normally closed contact of the relay of the electrical device with the previous priority.

[0095] Taking glass lift, rear defrost, and electric pedal as examples, the connection relationship includes: the glass lift switch is connected to the glass lift motor relay coil end, the glass lift motor is connected to the normally open contact of the glass lift motor relay; the normally closed contact of the glass lift motor relay is connected to the common end of the rear defrost relay; the rear defrost switch is connected to the coil end of the rear defrost relay, the rear defrost heating wire is connected to the normally open contact of the rear defrost relay, and the normally closed contact of the rear defrost relay is connected to the common end of the electric pedal relay; the electric pedal switch is connected to the coil end of the electric pedal relay, and the electric pedal motor is connected to the normally open contact of the electric pedal relay. The control logic is as follows:

[0096] When the glass lift switch is pressed, the glass lift motor relay coil is energized, and the glass lift motor power is turned on. At the same time, the normally closed contact of the glass lift motor relay connected to the common end of the rear defrost relay is disconnected, so the rear defrost power circuit is broken; similarly, the electric pedal power circuit is broken, so even if the rear defrost switch or electric pedal switch is pressed, the rear defrost or electric pedal cannot work;

[0097] When the glass lift switch is not pressed, the common end of the glass lift motor relay is connected to the normally closed contact. When the rear defrost switch is pressed, the rear defrost relay is activated, and the common end of the rear defrost relay is connected to the normally open contact, turning on the rear defrost power supply. Therefore, the rear defrost works, and the electric pedal power supply circuit cannot be connected at this time.

[0098] When the rear defrost switch is not pressed, press the electric pedal switch, the electric pedal relay will be activated, the electric pedal power will be turned on, and the electric pedal will work;

[0099] When the electric pedal switch is working, if the rear defrost switch or the window lift switch is pressed, the power supply of the electric pedal will be cut off to ensure that the electrical equipment with high priority is powered first.

[0103] 1) Read the wiring layout diagram, which is used to guide the correct connection between the electrical equipment and the power supply resource, or to guide after-sales maintenance; the wiring layout diagram is as follows Figure 5 As shown, the correspondence between the hole positions and the power supply resources is preset in the power distribution device; when the power supply resource is a fuse box, there are many fuses and relays on the fuse box. After the fuses and relays are installed, some external interfaces will be brought out to connect with the outside. The wiring layout diagram refers to the correspondence between these external interfaces and the fuse and relay pins.

[0104] 2) Read the insurance layout diagram. In this embodiment, the insurance layout diagram is as follows: Figure 6 As shown; the fuses on the fuse box are fixed, but each fuse can be assigned to which electrical equipment it is assigned to, and different assignments correspond to different output fuse layout diagrams.
