All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

It should be noted that the terms "comprising" and "having" and any variations thereof in the embodiments and figures herein are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.

The embodiment of the application discloses a vehicle power distribution system, a power distribution method, a vehicle and a storage medium, which can improve the flexibility of load power distribution. The following will describe in detail.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a vehicle power distribution system according to an embodiment of the disclosure. As shown in fig. 1, the vehicle power distribution system 100 may include: at least two power distribution demand modules, including a first power distribution demand module 111 and a second power distribution demand module 112, a power distribution management module 120, and a load 130. It should be noted that in some embodiments, a vehicle power distribution system may include 3 or more power distribution demand modules. For ease of description, the following will take the first power distribution requirement module 111 as an example, to describe operations that any of the power distribution requirement modules disclosed in the embodiments of the present application may perform.

The first power distribution demand module 111 may include any controller within the vehicle having power distribution demands, such as an autopilot controller (Smart Control Unit, SCU), the power distribution demands of the SCU may include turning on a look-around camera, turning on Off-board lighting fixtures, etc. when the vehicle is in Off gear, and the SCU may generate power distribution instructions according to the power distribution demands.

The first power distribution demand module 111 may include any switch on the vehicle, including but not limited to a physical switch or a virtual switch displayed on a large screen on board the vehicle. The switch may generate the power distribution instructions upon detecting a user pressing, clicking, etc. trigger operation.

The first power distribution requirement module 111 may further include a vehicle module having communication connection with other terminal devices such as a smart phone, an internet of things device, and the like, for example, the T-Box may receive a power distribution requirement input by a user through the smart phone, so as to generate a power distribution instruction.

The power distribution management module 120 may include an in-vehicle controller with a certain operation function, such as a microcontroller (Micro Control Unit, MCU), an electronic control unit (Electronic Control Unit, ECU), and the like. The power distribution management module 120 may be communicatively coupled to each power distribution demand module, and the respective power distribution demand module may be in data communication with the power distribution management module 120 based on the communication connection.

The load 130 may include any on-board module or component on the vehicle that needs to be powered, such as, but not limited to, an air conditioner, lights, a seat, and the like. The load 130 may be connected with the power distribution management module 120. The load 130 and the power distribution management module 120 may be connected through a communication interface, or may be directly driven by a hard wire, and the power distribution management module 120 may perform data transmission with the load 130 based on a connection such as a communication connection or a hard wire connection.

In an embodiment of the present application, the first power distribution demand module 111 may be configured to generate a power distribution instruction and send the power distribution instruction to the power distribution management module 120.

Wherein, the power distribution instructions may include power distribution requirements of the load, the power distribution requirements may include: load power-up, load power-down, or load no distribution demand. Load power-up may refer to requesting the battery to power the load, load power-down may refer to requesting the battery to stop powering the load, and load no-power-distribution requirements may refer to no-requirement for battery power.

The first power distribution demand module 111 may generate a power distribution instruction in response to a trigger operation input by a user, or may generate a power distribution instruction based on a preset control policy, which is not limited in particular.

It should be noted that, each power distribution instruction generated by the first power distribution demand module 111 may include a power distribution demand of one load, or may include a power distribution demand of a plurality of loads, which is not limited in particular.

For example, a user may trigger a user operation to turn on the interior ceiling lamp through a console input, and the first power distribution demand module 111 may detect the user operation and generate a power distribution command for powering on the interior ceiling lamp.

For example, the user may trigger the vehicle to enter the in-vehicle meditation mode through the in-vehicle large screen, and the first power distribution demand module 111 may detect a user operation triggering the in-vehicle meditation mode, generate a power distribution instruction, where the power distribution instruction includes power distribution demands as follows: the vehicle-mounted large screen, the loudspeaker, the seat, the air conditioner, the lamp control and the like are powered on, and the chassis electronic system, the SCU and the like are powered off.

The power distribution management module 120 is configured to receive power distribution instructions sent by at least two power distribution demand modules respectively. The power distribution instructions sent by the different power distribution demand modules can include power distribution demands for the same load, and can also include power distribution demands for different loads. If the different power distribution instructions include power distribution requirements for the same load, the power distribution requirements for the same load may be the same or different, and the power distribution instructions are not particularly limited.

For example, the power distribution demand module 111 may send power distribution instructions for powering up the air conditioner, and the power distribution demand module 112 may send power distribution instructions for powering up the lighting fixtures outside the vehicle and powering down the air conditioner.

In addition, different power distribution demand modules may send power distribution instructions to the power distribution management module 120 at the same time, or may send power distribution instructions to the power distribution management module 120 at different times, which is not limited in detail.

The power distribution management module 120 may be further configured to determine a first target power distribution state of the load according to a power distribution requirement of the load included in each of the power distribution instructions.

The power distribution management module 120 may receive power distribution instructions sent by one or more power distribution demand modules at the same time, where loads included in each power distribution instruction may be the same or different; the power distribution requirements of different power distribution orders for the same load may be the same or different.

If the power distribution demands for the same load in the power distribution instructions received by the power distribution management module 120 are the same, the power distribution management module 120 may determine the first target power distribution state of the load as the power distribution state corresponding to the power distribution demand included in any one of the power distribution instructions.

For example, at least two power distribution demand modules in the vehicle power distribution system may include a power distribution demand module 1, a power distribution demand module 2, and a power distribution demand module N (N > 2, which is a positive integer), the 3 power distribution demand modules each send a power distribution instruction to the power distribution management module 120, and each power distribution instruction includes: if the power distribution needs for powering up the vehicle audio, the power distribution management module 120 may determine a first target power distribution state for the vehicle audio (load) as a powered-up state.

If the power distribution requirements for the same load in the power distribution instructions received by the power distribution management module 120 are different, the power distribution management module 120 may determine the first target power distribution state of the load according to the power distribution requirements of the same load in the power distribution instructions. The specific embodiments can be as follows:

optionally, the power distribution management module 110 may be further configured to determine, when a power distribution requirement included in any one of the power distribution instructions is power-on of the load, a first target power distribution state of the load as a power-on state. That is, whenever one of the power distribution demand modules requests that the load be powered up, the load should be in a powered up state.

For example, at least two power distribution demand modules in a vehicle power distribution system may include a power distribution demand module N and a power distribution demand module n+1. The power distribution demand module N may send a power distribution instruction to the power distribution management module 120 that the power distribution demand is power on of the vehicle audio, and the power distribution demand module n+1 may send a power distribution instruction to the power distribution management module 120 that the power distribution demand is power off of the vehicle audio.

The power distribution demand module N requests the vehicle audio to be powered up, which indicates that the user operation detected by the power distribution demand module N requires the use of the vehicle audio, and therefore, even though the power distribution demand module n+1 may request the vehicle audio to be powered down for the purpose of saving electric energy, the power distribution management module 120 may determine the first target power distribution state of the vehicle audio (load) as the powered-up state.

Optionally, the power distribution management module 120 may be further configured to determine a first target power distribution state of the load as a power-off state when the power distribution requirements included in each power distribution instruction received by the power distribution management module 120 are not power-on of the load. Wherein, the distribution demand that each distribution instruction includes is not the load electricity, can include: the power distribution instructions include power distribution requirements that power down the load or no power distribution requirements for the load. That is, each power distribution demand module is in a power-off state only when it does not request power to the same load.

For example, at least two power distribution demand modules in a vehicle power distribution system may include a power distribution demand module N and a power distribution demand module n+1. The power distribution demand module N may send a power distribution instruction to the power distribution management module 120 that the power distribution demand is for the in-vehicle light fixture to be powered off, and the power distribution demand module n+1 may send a power distribution instruction to the power distribution management module 120 that the power distribution demand is for the in-vehicle light fixture to be powered off.

The vehicle power distribution system may also include other power distribution demand modules in addition to power distribution demand module N and power distribution demand module n+1, but the other power distribution demand modules do not send power distribution instructions to power distribution management module 120 that include the power distribution demands of the in-vehicle lights. Accordingly, the power distribution management module 120 may determine a first target power distribution state of the in-vehicle lights (loads) as a power outage state.

The power distribution management module 120 may also be configured to control the switching of the load to the first target power distribution state. Wherein the first target power distribution state may include: a powered-up state or a powered-down state. When the load is in the power-on state, the battery of the vehicle may supply power to the load, and after the battery supplies power to the load, the load may run or sleep, which is not particularly limited. When the load is in a powered-off state, the battery of the vehicle may stop supplying power to the load, and the load may not consume power.

That is, the final first target power distribution state of the load is distributed, commonly determined by the individual power distribution demand modules, and not determined by the power supply gear of the vehicle.

For example, when the power supply range of the vehicle is engaged in the On range, the respective loads of the vehicle may be in the power-On state according to the setting of the On range of the vehicle. At this time, the first power distribution demand module 111 included in the vehicle power distribution system may generate a power distribution instruction for the power outage of the air conditioner in the power distribution demand, and transmit the power distribution instruction to the power distribution management module 120, and the remaining power distribution demand modules may not transmit the power distribution instruction. The power distribution management module 120 may determine a first target power distribution state of the air conditioner as a power-off state according to the received power distribution instruction, and control the air conditioner to switch to the power-off state, so that the battery stops supplying power to the air conditioner to reduce unnecessary power consumption.

For example, when the power supply range of the vehicle is shifted into the Off range, the respective loads of the vehicle may be in the power-Off state according to the setting of the Off range of the vehicle. At this time, implementing the vehicle power distribution system as shown in the embodiment of the application may also realize that one or more loads are in a powered-on state when the vehicle power supply gear is engaged in the Off gear.

Furthermore, the final first target distribution state of the load is not determined by a certain distribution demand module alone, but by each distribution demand module included in the vehicle distribution system together: if a first power distribution demand module 111 is present to request power-up of a load, determining a first target power distribution state of the load as a power-up state; if all the power distribution demand modules do not request the load to be electrified, the first target power distribution state of the load is determined to be a power-off state, so that conflicts caused by different power distribution demands of a plurality of power distribution demand modules aiming at the same load request can be reduced, and all the loads can be reasonably distributed.

It can be seen that the vehicle power distribution system disclosed in the foregoing embodiments can be implemented without being limited by the power supply gear of the vehicle to distribute power to the load, so that the flexibility of distributing power to the load can be improved.

To more clearly illustrate the vehicle power distribution system disclosed in the embodiments of the present application, referring to fig. 2, fig. 2 is a schematic structural diagram of another vehicle power distribution system disclosed in one embodiment. As shown in fig. 2, the vehicle power distribution system 200 may include n+1 power distribution demand modules, M power distribution management modules, and M loads. Wherein M may be a positive integer greater than or equal to 3.

It should be noted that, when the vehicle power distribution system includes a plurality of power distribution management modules, the number of the power distribution management modules may be the same as or different from the number of the power distribution demand modules; the number of the power distribution management modules and the number of the loads are the same, or can be different, and the power distribution management modules and the loads are not limited in particular.

Optionally, as shown in fig. 2, to improve management efficiency, each load included in the vehicle power distribution system 200 may be respectively connected to one power distribution management module in a communication manner, and each power distribution management module may receive power distribution instructions sent by a plurality of power distribution demand modules, determine a first target power distribution state of a load connected to the power distribution management module according to the received power distribution instructions, and control the load to switch to the first target power distribution state.

In addition, in the vehicle power distribution system as shown in fig. 2, if the power distribution command generated by a certain power distribution demand module includes the power distribution demands of a plurality of loads, the power distribution demand module may send the power distribution command to the power distribution management module communicatively connected to the plurality of loads, respectively.

For example, as shown in fig. 2, the power distribution demand module 1, the power distribution demand module 2, the power distribution demand module 3, and the power distribution demand module n+1 may each transmit a power distribution instruction to the power distribution management module of the load x (2 < x < M), where the power distribution instruction transmitted by each power distribution demand module includes the power distribution demand of the load x. The power distribution management module of the load x can control the load x to be switched to the first target power distribution state after determining the first target power distribution state of the load x according to the received power distribution instruction, so that power distribution of the load x is realized.

Based on the vehicle power distribution system shown in the foregoing embodiment, the following describes a control strategy of the power distribution demand module when the power supply range of the vehicle is in the Off (Off) range.

In one embodiment, the first power distribution demand module 111 is further configured to generate a power distribution command for powering up the load when it is determined that power supply to the load is required; and continuously sending a power distribution command for powering up the load to the power distribution management module 120 when the power supply gear of the vehicle is in the off gear.

When the power supply gear is in the Off gear, even if the load is switched to the power-on state and then sends a successful notification to the power distribution management module 120, the first power distribution demand module 111 can continuously send a power distribution instruction that the power distribution demand is that the load is powered on to the power distribution management module 120, and continuously send the power distribution instruction that the power distribution demand is that the load is powered on, so that the load is maintained in the power-on state and is not influenced by the fact that the power supply gear of the vehicle is in the Off gear.

For example, if the first power distribution requirement module 111 needs to power up the load x, a power distribution instruction of powersupplyreq_x=cmdon may be continuously sent to the power distribution management module 120, where powersupplyreq_x may be used to indicate the power distribution requirement of the load x, and CmdOn may be used to indicate that the power distribution of the load is On, i.e. the load is powered up.

In addition, if there are multiple power distribution demand modules in the vehicle power distribution system that need to power up the load x at the same time, the multiple power distribution demand modules may continuously send power distribution instructions of powersupplyseq_x=cmdlon to the power distribution management module 120, respectively.

Whether one or more power demand modules sent a powersupplyreq_x=cmdon power distribution command, the power distribution management module 120 may determine the first target power distribution state of the load x as a powered-on state, and control the load x to switch to the powered-on state so that the power source supplies power to the load x.

In one embodiment, the first power distribution requirement module 111 is further configured to generate a power distribution instruction for powering down the load when it is determined that the power is required to be powered down; and, when the power supply gear of the vehicle is in the off gear, after sending a power distribution instruction for power-off of the load to the power distribution management module 120 once, stopping the power distribution instruction for power-off of the load for the power distribution demand.

For example, if the first power distribution demand module 111 no longer needs to power up the load x, the power distribution management module 120 may be sent a power supply command of powersupplyseq_x=cmdoff, where CmdOff may be used to indicate that the power distribution of the load is Off, i.e. the load is powered Off.

When the power distribution management module 120 receives a power distribution instruction of powersupplyreq_x=cmdaff, if no other power distribution demand module (such as the second power distribution demand module 112) requests to power up the load x, the power distribution management module 120 may determine the first target power distribution state of the load x as a power-off state, and control the load x to switch to the power-off state, so as to cut off the power supplied by the power source to the load x.

In one embodiment, the power distribution instructions generated by the first power distribution demand module 111 may include power distribution demands of a plurality of loads.

For example, the vehicle may provide a camping mode that requires turning on the refrigerator, turning on the Off lighting, and turning on the Off speakers when the vehicle is powered on when the vehicle enters the camping mode. The first power distribution demand module 111 may generate and continue to transmit power distribution instructions upon detecting that a camping pattern is triggered. Wherein the generated power distribution instructions may include: powersupplyreq_1= CmdOn, powerSupplyReq _2= CmdOn, powerSupplyReq _3=cmdon; powersupplyreq_1 may be used to represent the power distribution requirements of the refrigerator, powersupplyreq_2 may be used to represent the power distribution requirements of the exterior lighting fixtures, and powersupplyreq_3 may be used to represent the power distribution requirements of the exterior speakers.

After receiving the power distribution command, the power distribution management module 120 may determine the first target power distribution states of the refrigerator, the external lighting device and the external speaker as the power-on states, and control the three loads to be switched to the power-on states, so that the power supply supplies power to the three loads.

Therefore, when the power supply gear of the vehicle is engaged with the Off gear, the power-on or power-Off of the load can be flexibly controlled according to the actual power distribution requirement of the power distribution requirement module, so that the power distribution state of the load is not limited by the Off gear of the power supply gear.

The vehicle power distribution system shown in the foregoing embodiment may also flexibly control the power distribution of the load when the power supply gear of the vehicle is in the On (On) gear, and the following describes the control strategy of the power distribution demand module when the power supply gear of the vehicle is in the On gear.

In one embodiment, the first power distribution demand module 111 is further configured to generate a power distribution command for powering up the load when it is determined that power supply to the load is required; the method comprises the steps of,

when the power supply gear of the vehicle is in the on gear and the power is not required to be maintained to be powered on, after a power distribution command for powering on the load is sent to the power distribution management module 120 once, the power distribution command for powering on the load is stopped.

For example, the first power distribution demand module 111 may stop transmitting after transmitting a power distribution instruction of powersupplyreq_x=cmdon to the power distribution management module 120 when the load x is required to be powered up and when the load x is not required to be maintained to be powered up.

Or, when the power supply gear of the vehicle is in the starting gear and the load needs to be maintained to be powered on, a power distribution command for the power distribution demand to power the load is continuously sent to the power distribution management module 120, so that the load is maintained in a powered-on state.

In one embodiment, the first power distribution demand module 111 is further configured to generate a power distribution command for powering down the load when it is determined that the load needs to be powered down, and stop sending the power distribution command for powering down the load after sending the power distribution command for powering down the load once to the power distribution management module 120. That is, the first power distribution demand module 111 has the same transmission strategy of the power distribution instruction to transmit the load power outage to the power distribution management module 120 when the power supply range of the vehicle is in the off range and the on range.

In one embodiment, the power distribution command sent by the first power distribution demand module 111 to the power distribution management module 120 may be sent when the power source of the vehicle is in an on gear, and the triggering operation of the first mode is detected, and the triggering operation of the first mode may be user-triggered.

After receiving the power distribution command sent by the first power distribution demand module 111, the power distribution management module 120 may determine a first target power distribution state of the load according to the power distribution command sent by each power distribution demand module, and control the load to switch to the first target power distribution state, so that the load of the vehicle operates in the first mode.

The first mode may be, for example, an in-vehicle meditation mode, requiring power supply to loads such as in-vehicle atmosphere lamps, chassis electronics, etc. to be turned off in case the power is in On gear. The first power distribution demand module 111 may generate a corresponding power distribution instruction when it detects that the vehicle power source is in On gear and the in-vehicle meditation mode is triggered, and transmit the power distribution instruction to the power distribution management module 120 to cause the vehicle to enter the in-vehicle meditation mode.

After the vehicle enters the first mode, other power distribution demand modules other than the first power distribution demand module 111 may still trigger other power distribution demands, and the first mode may be interrupted.

To properly interrupt the first mode, the first power distribution demand module 111 may generate a first exit command according to a current original power distribution state of the load when the vehicle ground power supply gear is in an on gear and a triggering operation of the first mode is not detected, where the first exit command may include a power distribution demand of the load when exiting the first mode.

And the first power distribution demand module 111 may be further configured to, when detecting a triggering operation of the first mode, send a power distribution instruction sent by the first power distribution demand module 111 to the power distribution management module 120, so that the power distribution management module 120 controls the load to enter the first target power distribution state according to each received power distribution instruction.

The power distribution management module 120 is further configured to detect an interruption instruction for the load sent by the second power distribution demand module after the control load is switched to the first target power distribution state; the interrupt instruction includes the power distribution demand for the load by the second power distribution demand module 112. That is, the interrupt command may be a power distribution command sent by another power distribution demand module to the power distribution management module 120, where the interrupt command sent by the second power distribution demand module 112 includes the power distribution demand of the same load as the power distribution command sent by the first power distribution demand module 111.

The first power distribution requirement module 111 is further configured to generate a second exit instruction according to a detection result of the interrupt instruction by the power distribution management module 120 and the first exit instruction; and upon detecting an exit operation of the first mode, sending a second exit instruction to the power distribution management module 120. The exit operation of the first mode may be triggered by a user, or may be triggered automatically when the power distribution management module 120 detects an interrupt command, which is not limited in particular.

The detection result of the interrupt instruction by the power distribution management module 120 may include: the power distribution management module 120 detects an interrupt instruction; alternatively, the power distribution management module 120 does not detect an interrupt instruction.

Optionally, the first power distribution demand module 111 may be further configured to, when the power distribution management module 120 detects an interruption command, change a power distribution demand of a load in the first exit command to a power distribution demand without a load, so as to obtain a second exit command; and/or the number of the groups of groups,

optionally, the first power distribution requirement module 111 may be further configured to determine, when the power distribution management module 120 does not detect the interruption command, a power distribution requirement of the load in the first exit command as a power distribution requirement of the load in the second exit command.

The power distribution management module 120 is further configured to determine a second target power distribution state of the load according to the second exit instruction, and control the load to switch to the second target power distribution state.

By way of example, the following illustrates how the first mode may be interrupted, taking as an example that the first mode includes power distribution requirements for a plurality of loads.

S1, before the user triggers the first Mode (ONx Mode) through a triggering operation, the first power distribution demand module 111 may store the original power distribution state powersupplyst_loadx of each load into the load state array statefarray [ StateOFF, stateON, stateOFF, stateON, … …, stateON ] in real time.

The powersupplyst_loadx may represent a power distribution state of an xth load of the plurality of loads included in the first mode, the load state data StatusArray [ ] is used to store original power distribution states corresponding to the respective loads, stateOFF may be used to represent that the original power distribution states are power-off states, and StateON may be used to represent that the original power distribution states are power-on states.

S2, when the triggering operation of the first Mode (ONx Mode) is detected, the first power distribution demand module 111 can convert the original power distribution state in the load state Array StatusARRAy to a corresponding Out_ ONx Mode_Array instruction. Wherein Out ONx1Mode Array [ ] can be used to represent the first exit instruction.

For example, the load status Array StatusARRAy [ StateOFF, stateON, stateOFF, stateON, stateOFF, stateON, stateON ] may be converted to an Out_ ONx1Mode_Array [ CmdOff, cmdOn, cmdOff, cmdOn, cmdOff, cmdOn, cmdOn ] instruction. That is, the original power distribution status of any load corresponds to the power distribution demand of that load in the first exit command.

S3, when the triggering operation of the first Mode (ONx Mode) is detected, the first power distribution demand module 111 may also trigger to acquire the power distribution request Array in_ ONx1 mode_array= [ CmdOff, cmdOff, cmdOn, cmdOff, cmdOff, cmdOn, cmdOn ] of ONx1 Mode.

The power distribution request Array in_ ONx1mode_array [ ] may include power distribution requirements for each load IN the first Mode, and the first power distribution requirement module 111 may generate power distribution instructions including power distribution requirements for a plurality of loads from the power distribution request Array in_ ONx1mode_array [ ]. That is, the power distribution instructions generated by the first power distribution demand module 111 may include: load 1 is powered off, load 2 is powered off, load 3 is powered on, load 4 is powered off, load 5 is powered off, load 6 is powered on, and load 7 is powered on.

The first power distribution management module 120, after comprehensively considering the power distribution instructions sent by the plurality of power distribution demand modules, controls each load to enter a first target power distribution state corresponding to each load so as to enable the vehicle to enter a first mode.

The distribution request Array in_ ONx1mode_array [ ] may be stored IN the first distribution demand module 111 IN advance, and may be preset according to actual service demands. If the association relationship between the first power distribution demand module 111 and each load needs to be changed, the power distribution request Array in_ ONx mode_array [ ] is rewritten.

S4, after the vehicle enters the first Mode, if the load x is interrupted by the power distribution command PowerSuplyReq_x of the second power distribution demand module 112, the first power distribution demand module 111 may update the Out_ ONx1Mode_array [ ] Array in real time. The updating may include: the command for load x is set NoCmd. Wherein the power distribution instruction powersupplyreq_x sent by the second power distribution demand module 112 may be used to represent an interrupt instruction.

If the interrupt instruction includes: the load 1 and the load 4 are powered up, the load 3 and the load 7 are powered down, and then the Out_ ONx Mode_array [ ] Array can be obtained from

[ CmdOff, cmdOn, cmdOff, cmdOn, cmdOff, cmdOn, cmdOn ] is updated to the point that,

[ NoCmd, cmdOn, noCmd, noCmd, cmdOff, cmdOn, noCmd ]. The updated Out_ ONx1Mode_array [ ] Array may be used to represent a second exit instruction.

And S5, when the exit operation of the first Mode is detected, the first power distribution demand module 111 can send the updated Out_ ONx1Mode_array [ ] Array to the power distribution management module 120, so that the power distribution management module 120 determines respective second target power distribution states of the loads according to the second exit instruction, and controls the loads to switch to the respective corresponding second target power distribution states so as to exit the first Mode correctly.

To more clearly describe the power distribution state of each load before triggering the first mode, upon entering the first mode, and after exiting the first mode. Please refer to the following table:

table 1 load distribution status table

As can be seen from the table above:

load 1: the original power distribution State1 before the first mode operation is StateOFF (the exit array is set to be cmdioff), when the first mode is entered, the power distribution demand of the power distribution command on the load 1 is cmdioff, and then the power distribution State2 when the first mode is entered is still StateOFF.

During the first mode the power distribution demand of load 1 is interrupted by an interrupt command, the power distribution demand of load 1 by the interrupt command is CmdOn, and the power distribution demand of load 1 in the second exit command is NoCmd. Since the power distribution requirement of the interrupt command on the load 1 is cmdlen, although the power distribution requirement of the load 1 in the second exit command is NoCmd, the second target power distribution state of the load 1 after exiting the first mode is StateON.

Load 3: the original power distribution State1 before the first mode operation is StateOFF (the exit array is set to be cmdioff), the power distribution demand of the power distribution command on the load 3 when entering the first mode is cmdion, and the power distribution State2 when entering the first mode is StateON.

During the first mode the power distribution demand of load 3 is interrupted by an interrupt command, the power distribution demand of load 3 by the interrupt command is cmdioff, and the power distribution demand of load 3 by the second exit command is NoCmd. Because the demands of the interrupt instruction and the second exit instruction on the load 3 are not CmdOn, the second target power distribution state of the load 3 after exiting the first mode is StateOFF; the load 5 is the same.

Load 2: the original power distribution State1 before the first mode operation is StateON (set exit array is cmdion), and the power distribution demand of the power distribution command on the load 2 is cmdioff when the first mode is entered, but since other power distribution demand modules except the first power distribution demand module 111 may need to keep the load 2 powered up, the other power distribution demand modules continuously send the power distribution command with the power distribution demand of cmdion. Even if the power distribution demand of the load 2 by the power distribution command transmitted by the first power distribution demand module 111 is cmdioff when the first mode is entered, the power distribution State2 when the load 2 enters the first mode is still StateON.

There is no interrupt command for load 2 during the first mode, so the power distribution requirement of load 2 in the second exit command is cmdn, corresponding to the original power distribution State1 of load 2 before entering the first mode, and the second target power distribution State load of the load after exiting the first mode is StateON.

Load 4: the original power distribution State1 before the first mode operation is StateON (set exit array is cmdion), and the power distribution demand of the power distribution command on the load 3 when entering the first mode is cmdioff. Since the other power distribution demand modules except the first power distribution demand module 111 do not need the load 4 to remain powered on, only the first power distribution demand module 111 transmits a power distribution instruction with the power distribution demand being StateOFF to the load 4, and thus the power distribution State2 when the load 4 enters the first mode is StateOFF.

During the first mode the power distribution demand of the load 4 is interrupted, the power distribution demand of the load 4 by the interruption command is CmdOn, and the power distribution demand of the load 4 in the second exit command is NoCmd. Since the power distribution requirement of the interrupt command to the load 4 is cmdlen, although the power distribution requirement of the load 4 in the second exit command is NoCmd, the second target power distribution state of the load 4 after exiting the first mode is StateON.

The load 6 and the load 7 are similar to the aforementioned loads, and the following description will be omitted.

It can be seen that, based on the vehicle power distribution system shown in the foregoing embodiment, it is also possible to control the vehicle to correctly enter and exit the preset first mode when the vehicle power supply gear is shifted into the on gear, and to accommodate any interrupt request during the first mode.

In summary, based on the vehicle power distribution system shown in the foregoing embodiment, the power distribution state of the load can be unhooked from the power supply gear of the vehicle, and the cost of changing the vehicle power distribution system can be reduced.

For example, if the power distribution demand module N needs to increase the power distribution demands on the load 1, the load 4 and the load 5, only the corresponding logic codes need to be written into the power distribution demand module N according to the control policy of the power distribution demand module, and the power distribution management module communicatively connected to the load 1, the load 4 and the load 5 does not need to be changed.

If the power distribution demand module N needs to delete the power distribution demands on the load 2 and the load 3, only the logic codes related to the load 2 and the load 3 in the control strategy of the power distribution demand module are deleted in the power distribution demand module N, and the power distribution management module in communication connection with the load 1, the load 4 and the load 5 does not need to be changed.

If the power distribution demand module N needs to change the original power distribution demands on the load 1 and the load 3 into the power distribution demands on the load 2, the load 3 and the load 5, only the logic codes in the power distribution demand module N need to be changed according to the control strategy of the power distribution task module, and the power distribution management module in communication connection with the loads 1, 2, 3 and 5 does not need to be changed.

Based on this, the vehicle power distribution system disclosed in the embodiment of the application has low modification cost, further improves the flexibility of the vehicle power distribution system, is favorable for modification in an Over-the-Air Technology (OTA) mode, and can be suitable for the gradually increased power distribution requirement of the vehicle.
