All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It is to be noted that the terms "comprises" and "comprising" and any variations thereof in the examples and figures of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively 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 are detailed below.
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 convenience of description, the following description will take the first power distribution demand module 111 as an example, and describes operations that any power distribution demand module disclosed in the embodiments of the present application can perform.
The first power distribution requirement module 111 may include any controller having a power distribution requirement in the vehicle, such as a Smart Control Unit (SCU), and the power distribution requirement of the SCU may include turning on a look-around camera, turning on an illumination lamp outside the vehicle, and the like when the vehicle is in an Off gear, and the SCU may generate a power distribution instruction according to the power distribution requirement.
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 the vehicle's large screen. The switch may generate a power distribution instruction upon detecting a user press, click, or the like triggering operation.
The first power distribution demand module 111 may further include a vehicle module in communication connection with other terminal devices such as a smart phone and an internet of things device, for example, a T-Box, where the T-Box may receive a power distribution demand input by a user through the smart phone to generate a power distribution instruction.
The power distribution management module 120 may include an in-vehicle controller having a certain operation function, such as a Micro Control Unit (MCU), an Electronic Control Unit (ECU), and the like. The power distribution management module 120 may be communicatively coupled to each power distribution demand module, and each power distribution demand module may communicate data with the power distribution management module 120 based on the communicative coupling.
The load 130 may include any on-board module or component of the vehicle that requires power, such as, but not limited to, air conditioning, lights, seats, etc. The load 130 may be connected to the 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 this embodiment, the first power distribution requirement 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 distribution instruction can include the distribution demand of load, and the distribution demand can include: load power-up, load power-down, or no power distribution demand by the load. The load power-up may refer to requesting the battery to supply power to the load, the load power-down may refer to requesting the battery to stop supplying power to the load, and the load no-power-distribution requirement may refer to no requirement for supplying power to the battery.
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 the power distribution instruction based on a preset control policy, which is not limited in detail.
It should be noted that each power distribution instruction generated by the first power distribution requirement module 111 may include a power distribution requirement of one load, and may also include power distribution requirements of multiple loads, which is not limited specifically.
For example, a user may input a user operation for triggering turning on of the interior dome lamp through the console, and the first power distribution requirement module 111 may detect the user operation and generate a power distribution instruction in which the power distribution requirement is power on of the interior dome lamp.
For example, the user may trigger the vehicle to enter the in-vehicle meditation mode through the vehicle-mounted large screen, and the first power distribution requirement module 111 may detect a user operation triggering the in-vehicle meditation mode, and generate a power distribution instruction including the power distribution requirements: the vehicle-mounted large screen, the loudspeaker, the seat, the air conditioner, the lamp controller 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 may be configured to receive power distribution instructions respectively sent by the at least two power distribution demand modules. The power distribution instructions sent by 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 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 are not particularly limited.
For example, the power distribution demand module 111 may send a power distribution instruction that the power distribution demand is power on of an air conditioner, and the power distribution demand module 112 may send a power distribution instruction that the power distribution demand is power on of a lighting fixture outside the vehicle and power off of 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 specifically.
The power distribution management module 120 may be further configured to determine a first target power distribution state of the load according to the power distribution demand of the load included in each power distribution instruction.
The power distribution management module 120 may receive power distribution instructions sent by one or more power distribution demand modules at the same time, and the loads included in each power distribution instruction may be the same or different; the power distribution requirements of different power distribution commands for the same load may be the same or different.
If the power distribution requirements for the same load in each power distribution instruction 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 requirement included in any one power distribution instruction.
For example, the 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), where the above-mentioned 3 power distribution demand modules all send power distribution instructions to the power distribution management module 120, and each power distribution instruction includes: the power distribution management module 120 may determine a first target power distribution state of the vehicle audio (load) as a powered-on state.
If the power distribution demands 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 demands for the same load by synthesizing the power distribution instructions. Specific embodiments may be as follows:
optionally, the power distribution management module 110 may be further configured to determine the first target power distribution state of the load as the power-on state when the power distribution requirement included in any one of the power distribution instructions is that the load is powered on. That is, whenever a power distribution demand module requests a load to be powered up, the load should be in a powered-up state.
For example, at least two power distribution demand modules in the 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 can send a power distribution instruction that the power distribution demand is for powering on the vehicle audio to the power distribution management module 120, and the power distribution demand module N +1 can send a power distribution instruction that the power distribution demand is for powering off the vehicle audio to the power distribution management module 120.
The power distribution demand module N requests the vehicle audio to be powered on, which indicates that the user operation detected by the power distribution demand module N requires the vehicle audio to be used, and thus, even though the power distribution demand module N +1 may request the vehicle audio to be powered off 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-on state.
Optionally, the power distribution management module 120 may be further configured to determine the first target power distribution state of the load as the power failure state when the power distribution requirements included in each power distribution instruction received by the power distribution management module 120 are not for power supply to the load. Wherein, the distribution demand that each distribution instruction includes does not all do not load power up, can include: the power distribution instructions include a power distribution requirement that the load is powered off or no power distribution requirement is required for the load. That is, when each power distribution demand module does not request to power up the same load, the load is in a power-off state.
For example, the at least two power distribution demand modules in the vehicle power distribution system may include power distribution demand module N and power distribution demand module N + 1. The distribution demand module N can send a distribution instruction that the distribution demand is the power failure of the in-vehicle lamp to the distribution management module 120, and the distribution demand module N +1 can send a distribution instruction that the distribution demand is the power failure of the in-vehicle lamp to the distribution management module 120.
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 the power distribution management module 120 that include the power distribution demands of the in-vehicle light fixtures. Accordingly, the power distribution management module 120 may determine a first target power distribution state of the in-vehicle light fixtures (loads) as the power-off state.
The power distribution management module 120 may be further configured to control the load to switch to the first target power distribution state. Wherein the first target power distribution state may include: a power-up state or a power-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 operate or sleep, which is not limited specifically. When the load is in the power-off state, the battery of the vehicle may stop supplying power to the load, and the load does not consume power.
That is, the final first target distribution state of the load is distributed, determined collectively by the individual distribution demand modules, and not by the power source gear of the vehicle.
For example, when the power source gear of the vehicle is shifted into the On gear, each load of the vehicle may be powered up according to the setting of the On gear 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 command in which the power distribution demand is a power outage of the air conditioner, and transmit the power distribution command to the power distribution management module 120, and the remaining power distribution demand modules may not transmit the power distribution command. The power distribution management module 120 may determine the 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, thereby reducing unnecessary power consumption.
For example, when the power gear of the vehicle is engaged in the Off gear, various loads of the vehicle may be in a power-Off state according to the setting of the Off gear of the vehicle. At this time, the vehicle power distribution system as shown in the embodiment of the present application may also be implemented to enable one or more loads to be in a power-on state when the vehicle power source gear is engaged in the Off gear.
In addition, the final first target distribution state of the load is not determined by a certain distribution demand module alone, but is determined by all distribution demand modules included in the vehicle distribution system: if there is a first power distribution demand module 111 requesting to power up the load, the first target power distribution state of the load is determined as a power-up state; if each power distribution demand module does not request the load to be powered on, the first target power distribution state of the load is determined to be a power-off state, so that conflicts caused by the fact that the power distribution demands of a plurality of power distribution demand modules are different aiming at the same load request can be reduced, and power distribution can be reasonably carried out on each load.
It can be seen that, by implementing the vehicle power distribution system disclosed in the foregoing embodiment, the load can be distributed without being limited by the vehicle power source gear, so that the flexibility of power distribution to the load can be improved.
For more clearly explaining the vehicle power distribution system disclosed in the embodiment of the present application, please refer to fig. 2, and 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 is the same as or different from the number of the loads, and is not limited specifically.
Optionally, as shown in fig. 2, in order to improve management efficiency, each load included in the vehicle power distribution system 200 may be respectively in communication connection with one power distribution management module, 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 the load connected to the power distribution management module according to each received power distribution instruction, and control the load to switch to the first target power distribution state.
In the vehicle power distribution system shown in fig. 2, if the power distribution command generated by a certain power distribution demand module includes power distribution demands of a plurality of loads, the power distribution demand module may transmit the power distribution command to each of the power distribution management modules communicatively connected to the plurality of loads.
For example, as shown in fig. 2, the distribution demand module 1, the distribution demand module 2, the distribution demand module 3, and the distribution demand module N +1 may all send a distribution instruction to a distribution management module with a load x (2 < x < M), where the distribution instruction sent by each distribution demand module includes a distribution demand with 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, and therefore power distribution of the load x is achieved.
Based on the vehicle power distribution system shown in the foregoing embodiment, the following describes the control strategy of the power distribution demand module when the power source gear of the vehicle is in the Off (Off) gear.
In one embodiment, the first power distribution requirement module 111 may be further configured to generate a power distribution instruction that the power distribution requirement is for powering on the load when it is determined that power needs to be supplied to the load; and when the power source gear of the vehicle is in the off gear, continuously sending a power distribution instruction with a power distribution requirement of powering on the load to the power distribution management module 120.
When the power source gear is in the Off gear, even if the power distribution management module 120 is informed of successful power supply after the load is switched to the power supply state, the first power distribution demand module 111 may continuously send the power distribution instruction with the power distribution demand being the power supply of the load to the power distribution management module 120, and continuously send the power distribution instruction with the power distribution demand being the power supply of the load, so that the load is maintained in the power supply state and is not affected by the fact that the power source gear of the vehicle is in the Off gear.
For example, if the first power distribution demand module 111 needs to power up the load x, a power supply req _ x ═ CmdOn power distribution command may be continuously sent to the power distribution management module 120, where the power supply req _ x may be used to indicate that the power distribution demand of the load x is On, and the CmdOn may be used to indicate that the power distribution of the load is On, that is, 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 supply req _ x ═ CmdOn power distribution commands to the power distribution management module 120, respectively.
Whether one or more power distribution demand modules send a power supply req _ 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 power-on state, and control the load x to switch to the power-on state, so that the power supply supplies power to the load x.
In one embodiment, the first power distribution requirement module 111 may be further configured to generate a power distribution instruction that the power distribution requirement is a power outage of the load when it is determined that the power outage of the load is required; and when the power supply gear of the vehicle is in the closing gear, after a power distribution instruction with a power distribution requirement of power outage of the load is sent to the power distribution management module 120, stopping the power distribution instruction with the power distribution requirement of power outage of the load.
For example, if the first power distribution demand module 111 no longer needs to power on the load x, the power distribution demand module may send a power supply req _ x ═ CmdOff power distribution command to the power distribution management module 120, and then stop sending the power distribution command, where the CmdOff power distribution command may be used to indicate that the power distribution of the load is Off, that is, the load is powered Off.
When the power distribution management module 120 receives a power distribution command with PowerSupplyReq _ x ═ cmdef, if no other power distribution demand module (for example, the second power distribution demand module 112) requests to power on 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 supply of the power supply 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, a vehicle may provide a camping mode in the field, when the vehicle enters the camping mode, requiring turning on the refrigerator, turning on the exterior lighting fixtures, and turning on the exterior speakers when the vehicle power is Off. The first power distribution demand module 111 may generate and continuously transmit power distribution instructions upon detecting a trigger of the camping mode in the field. Wherein the generated power distribution instructions may include: PowerSupplyReq _1 ═ CmdOn, PowerSupplyReq _2 ═ CmdOn, and PowerSupplyReq _3 ═ CmdOn; PowerSupplyReq _1 may be used to represent power distribution requirements for the refrigerator, PowerSupplyReq _2 may be used to represent power distribution requirements for the exterior lighting fixtures, and PowerSupplyReq _3 may be used to represent power distribution requirements for the exterior speakers.
After receiving the power distribution instruction, the power distribution management module 120 may determine a first target power distribution state of the refrigerator, the exterior lighting fixture, and the exterior speaker as a power-on state, and control the three loads to switch to the power-on state, so that the power supply supplies power to the three loads.
Therefore, by implementing the vehicle power distribution system, when the power supply gear of the vehicle is connected to 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 power supply gear Off gear.
The vehicle power distribution system shown in the foregoing embodiment may also flexibly control power distribution of the load when the power supply gear of the vehicle is in the On gear, and the following description introduces a 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 requirement module 111 may be further configured to generate a power distribution instruction that the power distribution requirement is for powering on the load when it is determined that power needs to be supplied to the load; and the number of the first and second groups,
when the power source gear of the vehicle is in the open gear and the load is not required to be maintained to be powered on, after the power distribution instruction with the power distribution requirement as the load power-on is sent to the power distribution management module 120 once, the power distribution instruction with the power distribution requirement as the load power-on is stopped from being sent.
For example, the first power distribution demand module 111 may stop sending the power distribution command of PowerSupplyReq _ x ═ CmdOn to the power distribution management module 120 once when the load x needs to be powered on and does not need to be powered on.
Alternatively, when the power source gear of the vehicle is in the open gear and the load needs to be maintained powered on, a power distribution instruction that the power distribution requirement is the power on of the load is continuously sent to the power distribution management module 120, so that the load is maintained in the power on state.
In one embodiment, the first power distribution demand module 111 may be further configured to generate a power distribution instruction with the power distribution demand of the load being powered off when it is determined that the load needs to be powered off, and stop sending the power distribution instruction with the power distribution demand of the load being powered off after sending the power distribution instruction with the power distribution demand of the load being powered off to the power distribution management module 120 once. That is, the first power distribution demand module 111 has the same transmission strategy for transmitting the power distribution instruction for load outage to the power distribution management module 120 when the power supply position of the vehicle is in the off-position and the on-position.
In one embodiment, the power distribution instruction sent by the first power distribution requirement module 111 to the power distribution management module 120 may be that the power source of the vehicle is in an open gear, and the trigger operation of the first mode is detected, and the trigger operation of the first mode may be user-triggered.
After receiving the power distribution instruction 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 by combining the power distribution instructions sent by the power distribution demand modules, 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.
For example, the first mode may be an in-vehicle meditation mode requiring the power supply to loads such as vehicle mood lights, chassis electronics, etc. to be turned off with the power supply in On gear. The first power distribution demand module 111 may generate a corresponding power distribution instruction and transmit the power distribution instruction to the power distribution management module 120 to enter the in-vehicle meditation mode when it is detected that the vehicle power is in the On gear and the in-vehicle meditation mode is triggered.
When 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 requirement module 111 may generate a first exit instruction according to the current original power distribution state of the load when the power supply gear of the vehicle is in the open gear and the triggering operation of the first mode is not detected, and the first exit instruction may include the power distribution requirement of the load when exiting the first mode.
And the first power distribution demand module 111 may be further configured to send, when the trigger operation of the first mode is detected, 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 interrupt instruction for the load sent by the second power distribution demand module after the load is controlled to be switched to the first target power distribution state; the interrupt instruction includes the power distribution demand of the second power distribution demand module 112 for the load. That is, the interruption instruction may be a power distribution instruction sent by another power distribution demand module to the power distribution management module 120, and the interruption instruction sent by the second power distribution demand module 112 and the power distribution instruction sent by the first power distribution demand module 111 include power distribution demands of the same load.
The first power distribution demand module 111 is further configured to generate a second quit instruction according to the detection result of the power distribution management module 120 on the interrupt instruction and the first quit instruction; and, upon detecting the exit operation of the first mode, sending a second exit instruction to the power distribution management module 120. The exit operation in the first mode may be triggered by a user, or may be triggered automatically when the power distribution management module 120 detects an interrupt instruction, which is not limited in particular.
The detection result of the power distribution management module 120 for the interrupt instruction 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 interrupt instruction, change a power distribution demand of a load in the first exit instruction into a load-less power distribution demand, so as to obtain a second exit instruction; and/or the presence of a gas in the gas,
optionally, the first power distribution demand module 111 may be further configured to determine, when the power distribution management module 120 does not detect the interrupt instruction, the power distribution demand of the load in the first exit instruction as the power distribution demand of the load in the second exit instruction.
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.
Illustratively, the following illustrates how the first mode may be interrupted, taking as an example that the first mode includes a power distribution requirement for a plurality of loads.
S1, before the user triggers the first Mode (ONx1Mode) through the trigger operation, the first power distribution demand module 111 may store the original power distribution status PowerSupplySt _ Loadx of each load into the load status array StatusArray [ StateOFF, StateON, … …, StateON ] in real time.
The powersupplySt _ Loadx may indicate a power distribution state of an xth load of the multiple loads included in the first mode, the load state data StatusArray [ ] is used to store an original power distribution state corresponding to each load, StateOFF may be used to indicate that the original power distribution state is a power-off state, and StateON may be used to indicate that the original power distribution state is a power-on state.
S2, when the trigger operation of the first Mode (ONx1Mode) is detected, the first power distribution demand module 111 may convert the original power distribution status in the load status Array StatusArray [ ] into the corresponding Out _ ONx1Mode _ Array [ ] command. Out _ ONx1Mode _ Array [ ] is available to represent the first exit instruction.
For example, the load state Array StatusArray [ StateOFF, StateON, StateOFF, StateON, StateOFF ], StateON ] may be converted to the Out _ ONx1Mode _ Array [ CmdOff, CmdOn, CmdOff, CmdOn, CmdOn ] instructions. That is, the original power distribution state of any load corresponds to the power distribution demand of that load in the first exit instruction.
S3, when detecting the triggering operation of the first Mode (ONx1Mode), the first power distribution demand module 111 may further trigger obtaining the power distribution request Array IN _ ONx1Mode _ Array of ONx1Mode ═ CmdOff, cmdeon, CmdOff, cmdeof, cmdeon ].
The distribution request Array IN _ ONx1Mode _ Array [ ] may include distribution requirements of the respective loads IN the first Mode, and the first distribution requirement module 111 may generate a distribution instruction including the distribution requirements of the plurality of loads according to the distribution request Array IN _ ONx1Mode _ Array [ ]. That is, the power distribution instructions generated by the first power distribution demand module 111 may include: the power of the load 1 is cut off, the power of the load 2 is cut off, the power of the load 3 is cut off, the power of the load 4 is cut off, the power of the load 5 is cut off, the power of the load 6 is cut off, and the power of the load 7 is cut off.
The first power distribution management module 120 controls each load to enter a corresponding first target power distribution state after comprehensively considering the power distribution instructions sent by the plurality of power distribution demand modules, so that the vehicle enters a first mode.
The power distribution request Array IN _ ONx1Mode _ Array [ ] can be stored IN the first power distribution demand module 111 IN advance, and can 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 _ ONx1Mode _ Array [ ] is rewritten.
S4, after the vehicle enters the first Mode, if the load x is interrupted by the power distribution command PowerSupplyReq _ 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 instruction corresponding to load x is set NoCmd. The power distribution instruction PowerSupplyReq _ x sent by the second power distribution demand module 112 may be used to indicate an interrupt instruction.
If the interrupt instruction includes: load 1 and load 4 are powered up and load 3 and load 7 are powered down, the Out _ ONx1Mode _ Array [ ] Array can be selected from
[ CmdOff, CmdOn, CmdOff, CmdOn, CmdOff, CmdOn, CmdOn ] is updated to,
[ NoCmd, CmdOn, NoCmd, NoCmd, CmdOff, CmdOn, NoCmd ]. The updated Out _ ONx1Mode _ Array [ ] Array may be used to represent the second exit instruction.
S5, when detecting the exiting operation of the first Mode, the first power distribution demand module 111 may send the updated Out _ ONx1Mode _ Array [ ] Array to the power distribution management module 120, so that the power distribution management module 120 determines the second target power distribution state of each load according to the second exiting instruction, and controls each load to switch to the corresponding second target power distribution state, so as to exit the first Mode correctly.
To more clearly describe the power distribution status of the respective loads before triggering the first mode, when entering the first mode, and after exiting the first mode. Please refer to the following table:
TABLE 1 load distribution State Table
Figure BDA0003280086900000151
As can be seen from the above table:
load 1: the original power distribution State1 before the first mode operation is StateOFF (the exit array is set to CmdOff), the power distribution demand of the power distribution command to the load 1 when entering the first mode is CmdOff, and the power distribution State2 when entering the first mode 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 the interrupt command to load 1 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 for the load 1 is CmdOn, 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 still StateON.
And (3) loading: the original power distribution State1 before the first mode operation is StateOFF (the exit array is set to cmdeof), the power distribution demand of the power distribution instruction to the load 3 when entering the first mode is cmdeon, 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 the interrupt command to load 3 is CmdOff, and the power distribution demand of load 3 in the second exit command is NoCmd. Since the requirements of the interrupt command and the second exit command on the load 3 are not CmdOn, the second target power distribution state of the load 3 is StateOFF after the first mode exits; the load 5 works the same.
And (3) loading 2: the original power distribution State1 before the first mode operation is StateON (the exit array is set to CmdON), and the power distribution demand of the power distribution command for the load 2 when entering the first mode is CmdOff, but since other power distribution demand modules except the first power distribution demand module 111 may require the load 2 to be powered on, the other power distribution demand modules continuously send the power distribution command with the power distribution demand of CmdON. Even though the power distribution demand to the load 2 by the power distribution command sent by the first power distribution demand module 111 when entering the first mode is cmdff, the power distribution State2 when the load 2 enters the first mode is still StateON.
There is no interrupt command to load 2 during the first mode, so the power distribution requirement of load 2 in the second exit command is CmdOn, corresponding to the original power distribution State1 of load 2 before entering the first mode, and the second target power distribution State load of load after exiting the first mode is StateON.
And (4) loading: the original power distribution State1 before the first mode of operation is StateON (the exit array is set to CmdON), and the power distribution demand of the power distribution command to the load 3 when entering the first mode is CmdOff. Since the other power distribution demand modules except the first power distribution demand module 111 do not need the load 4 to be powered on, only the first power distribution demand module 111 sends the 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 requirement of load 4 is interrupted, the power distribution requirement of load 4 is CmdOn by the interrupt command, and the power distribution requirement of load 4 in the second exit command is NoCmd. Since the power distribution demand of the interrupt command for the load 4 is CmdOn, although the power distribution demand 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 loads 6 and 7 are similar to the aforementioned loads and will not be described in detail below.
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 range is engaged in the open range, and to accommodate any interruption request during the first mode.
In summary, based on the vehicle power distribution system shown in the foregoing embodiment, in addition to the power distribution state of the load being decoupled from the power source gear of the vehicle, the cost of changing the vehicle power distribution system can be reduced.
For example, if the distribution demand module N needs to newly increase the distribution demands for the loads 1, 4 and 5, the corresponding logic code only needs to be written into the distribution demand module N according to the control policy of the distribution demand module, and the distribution management module in communication connection with the loads 1, 4 and 5 does not need to be changed.
If the distribution demand module N needs to delete the distribution demands for the loads 2 and 3, the logic codes related to the loads 2 and 3 in the control strategy of the distribution demand module just need to be deleted in the distribution demand module N, and the distribution management module communicatively connected to the loads 1, 4 and 5 does not need to be changed.
If the distribution demand module N needs to change the original distribution demand for the load 1 and the load 3 into the distribution demand for the load 2, the load 3, and the load 5, the logic code in the distribution demand module N only needs to be changed according to the control strategy of the distribution service demand module, and the 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 change cost, the flexibility of the vehicle power distribution system is further improved, the change is facilitated in an Over-the-Air Technology (OTA) mode, and the vehicle power distribution system can adapt to the gradually increased power distribution requirements of the vehicle.
