[0036] It should be understood that when used in the present specification and the appended claims, the term "comprising" indicates the presence of described features, wholes, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or combinations thereof.

[0037] It should also be understood that the term “and / or” used in the specification and appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0038] As used in the specification and appended claims of this application, the term "if" can be interpreted as "when" or "uponce" or "in response to determining" or "in response to detecting", depending on the context. Similarly, the phrase "if it is determined" or "if [described condition or event] is detected" can be interpreted as meaning "uponce it is determined" or "in response to determining" or "uponce [described condition or event] is detected" or "in response to detecting [described condition or event]", depending on the context.

[0039] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0040] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. appearing in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0041] With the development of new energy vehicles, in order to better provide services to users, the functions of vehicles are constantly increasing, and the power consumption of the whole vehicle is also increasing. In order to achieve the lightweight of the vehicle, and there is a need for no battery in the vehicle to start the engine, the capacity of the battery is gradually reduced.

[0042] During the vehicle production process, the vehicle needs to complete various assembly processes on the production line, such as battery assembly, software program flashing, seat and wiper inspection, etc.

[0043] At present, when the vehicle is on the production line, the battery cannot be charged, and some assembly processes need to be completed under the power supply of the battery (low voltage power supply), for example, the flashing of the software program needs to be completed when the power mode is ON (on state). As the vehicle functions increase, the assembly time of the entire production line increases, and the battery power consumption increases. Due to insufficient battery power, the battery will be depleted during the vehicle assembly process, and the vehicle cannot complete all the assembly processes and the vehicle cannot be offline, resulting in reduced vehicle production efficiency.

[0044] In view of the problem that the battery cannot support the entire vehicle assembly due to insufficient battery power, the inventor has come up with the following solution based on power saving: in the assembly process that does not require battery power, the battery power state can be manually switched to OFF (off state); in the assembly process that requires battery power, the battery power state can be manually switched to ON. This method manually switches the battery power state, which is not only cumbersome, but may also lead to errors in the battery power state switching.

[0045] The inventors came up with the following solutions based on the power supply:

[0046] Solution 1: Use the high-voltage system to recharge the battery when the battery power mode is in the ON position. However, since the vehicle is generally in factory mode during the assembly stage of the production line, the high-voltage system is not allowed to be powered on when the battery power mode is in the ON position. Therefore, this method is not feasible.

[0047] Solution 2: Production line transformation, adding charging equipment to the production line to charge the battery. However, production line transformation takes a long time, is expensive, and affects vehicle production during the production line transformation. Therefore, this method is not feasible.

[0048] Based on the above problems, the inventor proposed the method of the present application. When the vehicle is on the production line, the current state of the vehicle is set according to the vehicle state required for vehicle assembly. By detecting the current state of the vehicle, it is determined whether the battery can be charged. If the current state of the vehicle meets the preset requirements, the high-voltage system in the vehicle can be controlled to charge the battery, thereby avoiding the problem of the vehicle being unable to complete assembly and the vehicle being unable to go offline due to low battery power.

[0049] The following is a detailed description of the power management method for vehicles on the production line of an embodiment of the present application.

[0050] Figure 1 A schematic flow chart of a power management method for a vehicle on a production line provided by the present application is shown, referring to Figure 1 , the method is described in detail as follows:

[0051] S101, when a vehicle is in a production line assembly stage, detecting a current state of the vehicle, wherein the current state of the vehicle is determined based on a vehicle assembly process that currently needs to be performed.

[0052] In this embodiment, there is a production line for vehicle production when the vehicle is produced. Different workstations are set on the production line. Different assembly processes are performed when the vehicle is at different workstations. For example, there are software flashing stations, coolant filling stations, and vehicle equipment inspection stations on the production line. Vehicle equipment may include seats, wipers, air conditioners, etc. After the vehicle enters the production line assembly stage, the battery and wiring harness can be installed first. After the battery and wiring harness are installed, the battery powers the entire vehicle. Through the arrangement of workstations, the high-voltage system insulation test is first completed, so that the high-voltage system allows high voltage power-on to ensure power safety.

[0053] In this embodiment, different vehicle assembly processes may have different requirements for the vehicle status. For example, when performing process A, the vehicle's power status needs to be set to the off state (OFF position), and the power status represents the state of the battery; when performing the software flashing process, the vehicle's power status needs to be set to the on state (ON position).

[0054] In this embodiment, the current state of the vehicle may include the vehicle mode and the power state of the battery. The current state of the vehicle may be obtained from the central domain controller by the low-voltage power management system in the vehicle. The current state of the vehicle may be continuously detected at a preset frequency to timely detect changes in the vehicle state and determine whether the battery needs to be charged.

[0055] In this embodiment, the vehicle assembly process that needs to be performed by the vehicle at the current time can be determined by the diagnostic device scanning the identification code on the workstation. Or it can be determined by the diagnostic device (cloud) according to the vehicle location and the stage it is in. After the diagnostic device determines the vehicle assembly process that needs to be performed at the moment, the diagnostic device sends a diagnostic command to the vehicle, and the diagnostic command includes the state that the vehicle needs to switch to. The vehicle switches states according to the diagnostic command.

[0056] Specifically, after receiving a first instruction (diagnostic command) sent by a diagnostic device, the state of the vehicle is controlled to be switched based on the state indication of the vehicle in the first instruction, wherein the first instruction is generated after the diagnostic device determines the vehicle assembly process that currently needs to be executed by the vehicle and based on the state requirements of the vehicle by the vehicle assembly process.

[0057] As an example, after determining that the vehicle assembly process that needs to be executed currently is a software flashing process, the diagnostic device generates a first instruction, and the vehicle status indication in the first instruction includes that the power state of the battery is on and the vehicle mode is factory mode. After receiving the first instruction sent by the diagnostic device, the vehicle controls the power state of the battery to be switched to the on state and the vehicle mode to be switched to the factory mode based on the vehicle status indication in the first instruction, and the vehicle status is that the power state is on and the vehicle mode is factory mode.

[0058] S102: If the current state of the vehicle satisfies a preset condition, controlling a high-voltage system in the vehicle to charge a battery, wherein the preset condition indicates that the vehicle assembly process is at a stage where the high-voltage system is allowed to be started.

[0059] In the present embodiment, the preset condition is pre-set, and the preset condition is determined based on the vehicle state required by the vehicle assembly process that allows the high-voltage system to be started.

[0060] In this embodiment, the preset condition may include a first condition, wherein the first condition includes that the power state is an off state and the vehicle mode is a factory mode.

[0061] The preset condition may further include a second condition, the second condition including that the power state is a start-up state and the vehicle mode is a non-factory mode.

[0062] In this embodiment, after determining that the current state of the vehicle meets the preset conditions, the low-voltage power management system sends a charging request to the vehicle controller, and the charging request is used to instruct the vehicle controller to start the charging mode so that the high-voltage system in the vehicle charges the battery. The high-voltage system includes power batteries, etc.

[0063] In another embodiment, if the current state of the vehicle does not satisfy the preset condition, the high voltage system in the vehicle is controlled to prohibit charging of the battery.

[0064] For example, since the vehicle is in factory mode, if the power state of the battery is on, the high-voltage system is not allowed to start in order to ensure safety. Therefore, if the current state of the vehicle is that the power state is on and the vehicle mode is factory mode, the high-voltage system is prohibited from charging the battery.

[0065] In this application, when the vehicle is in the assembly stage of the production line, the current state of the vehicle is detected, and the current state is determined based on the vehicle assembly process that needs to be executed at present. If the current state of the vehicle meets the preset conditions, the high-voltage system of the vehicle is controlled to charge the battery. When the vehicle is in the assembly stage of the production line and the current state meets the preset requirements, the high-voltage system can be controlled to charge the battery. Compared with the existing situation that the battery cannot be charged in the assembly stage of the production line, the present application can also charge the battery in the assembly stage of the production line, which can ensure the battery power, and then ensure that the battery can better serve the assembly process. The present application will not cause the vehicle assembly to stagnate due to battery depletion, so that the vehicle can be assembled as soon as possible, improving the production efficiency of the vehicle.

[0066] In a possible implementation manner, the implementation method of step S102 may further include:

[0067] If the current state of the vehicle satisfies a preset condition, a target assembly process that needs to be powered by a battery among all remaining vehicle assembly processes is obtained.

[0068] Find the assembly time of each target assembly process. Calculate the sum of the assembly time of all target assembly processes to get the total power consumption time. Preset which vehicle assembly process needs battery power supply and the assembly time of each vehicle assembly process.

[0069] Get the remaining battery power. Estimate the estimated usage time of the remaining power.

[0070] The difference between the estimated usage time and the total power usage time is calculated. If the difference is greater than a preset value, it is determined that the battery power is sufficient to support the remaining vehicle assembly process and there is no need to charge the battery.

[0071] If the difference is less than or equal to a preset value, it is determined that the battery power is insufficient, and the high voltage system in the vehicle is controlled to charge the battery.

[0072] In this application, the current state of the vehicle is taken into consideration. When the current state meets the preset conditions, it is also considered whether the remaining power of the battery can support the remaining vehicle assembly process, and then it is determined whether to charge the battery, which not only ensures the completion of the vehicle assembly but also saves electricity.

[0073] In a possible implementation, since the battery has a certain capacity, the battery can reach a fully charged state after charging for a period of time. In order to save energy, after the charging time of the battery reaches a preset time, the high-voltage system can be controlled to stop charging the battery.

[0074] like Figure 2 Specifically, after step S102, the method may further include:

[0075] S201, starting from controlling a high voltage system in the vehicle to charge the battery, counting the continuous charging time of the battery.

[0076] In this embodiment, the timing starts from the moment when the battery starts to be charged, and the continuous charging time of the battery is counted.

[0077] S202, after the continuous charging time reaches a preset time, controlling the high voltage system in the vehicle to stop charging the battery.

[0078] In this embodiment, the preset time can be determined according to the charging performance of the battery. For example, the maximum charging time of the battery can be 5 hours, that is, the battery is fully charged after charging for 5 hours, and the preset time can be set to 5 hours.

[0079] Alternatively, the preset time is determined according to the total assembly time of the vehicle, etc. For example, the preset time can be set to 1.5 hours, etc.

[0080] In this embodiment, after the continuous charging time reaches the preset time, the low-voltage power energy management system sends a stop charging request to the vehicle controller. The stop charging request is used to instruct the vehicle controller to exit the charging mode so that the high-voltage system stops charging the battery.

[0081] In this embodiment, if the high-voltage system needs to stop charging the battery due to a change in the vehicle state before the continuous charging time reaches the preset time, the timing is stopped when charging the battery is stopped.

[0082] In the present application, the continuous charging time of the battery is counted when the battery starts to be charged. After determining that the continuous charging time of the battery reaches a preset time, the charging of the battery is stopped, which not only meets the requirement of charging the battery, but also saves energy.

[0083] In a possible implementation, when the current state of the vehicle does not meet the preset conditions, if it is detected that the currently executed vehicle assembly process has been completed, the current state of the vehicle can be switched to a state that meets the preset conditions so as to charge the battery in time.

[0084] In one possible implementation, in order to charge the battery in time, when the power state of the battery is on, if the vehicle assembly process that needs to be currently executed is completed, the power state of the battery can be switched from on to off so that the high-voltage system can charge the battery.

[0085] Specifically, if the vehicle assembly process currently to be executed is a software flashing process, during the software flashing process, the power state of the battery is on, and the vehicle mode is a factory mode.

[0086] After the software flashing process is completed, the diagnostic device may send a second instruction to the vehicle.

[0087] After receiving the second instruction sent by the diagnostic device, the vehicle controls the power state of the battery to be off and the vehicle mode to be factory mode based on the status indication of the vehicle in the second instruction, wherein the second instruction is sent by the diagnostic device to the vehicle after determining that the software flashing process is completed, and the status in the second instruction only includes the power state being off and the vehicle mode being factory mode.

[0088] In one possible implementation, after the vehicle is assembled and is no longer in the production line assembly stage, the vehicle can exit the factory mode, and the low-voltage power management system in the vehicle can detect the remaining power of the battery and determine whether the high-voltage system is needed to charge the battery based on the remaining power of the battery.

[0089] like Figure 3 As shown, in a possible implementation, the vehicle may include a central domain controller, a low-voltage power management system, and a vehicle controller. Below, the method of the present application is described by taking the vehicle software flashing as an example.

[0090] S11, the diagnostic device detects that the vehicle assembly process currently to be executed is a software flashing process.

[0091] S12, the diagnostic device determines the state that the vehicle needs to switch to based on the determined vehicle assembly process, and generates a first instruction based on the state that the vehicle needs to switch to, wherein the first instruction includes that the vehicle mode that the vehicle needs to switch to is the factory mode and the power state of the battery is the on state.

[0092] S13, the diagnostic device sends a first instruction to the central domain controller.

[0093] S14, after receiving the first instruction, the central domain controller switches the vehicle mode to the factory mode and the power state of the battery to the on state.

[0094] S15, the low-voltage power management system reads from the central domain controller that the vehicle mode is the factory mode and the battery power state is the on state.

[0095] In this embodiment, when the vehicle is in the assembly stage of the production line, the low-voltage power management system ignores the battery power value and can only focus on the vehicle status, and determines whether to recharge the battery according to the vehicle status.

[0096] S16, the low-voltage power management system sends a request to prohibit power replenishment to the vehicle controller.

[0097] S17, after receiving the request to prohibit charging, the vehicle controller controls the high-voltage system to be in a closed state to prohibit the high-voltage system from charging the battery.

[0098] S18, the diagnostic device detects that the software flashing process is completed, and the diagnostic device sends a second instruction to the central domain controller. The second instruction includes that the vehicle mode to be switched to is the factory mode and the power state of the battery is off.

[0099] S19, after receiving the second instruction, the central domain controller switches the vehicle mode to the factory mode and the power state of the battery to the off state.

[0100] S20, the low-voltage power management system reads from the central domain controller that the vehicle mode is the factory mode and the power state of the battery is the off state.

[0101] S21, the low-voltage power management system sends a power replenishment request to the vehicle controller.

[0102] S22, after receiving the charging request, the vehicle controller turns on the high-voltage system so that the high-voltage system charges the battery.

[0103] In actual use, after step S22, the diagnostic equipment can detect the next vehicle assembly process, determine the state that the vehicle needs to switch to next based on the next vehicle assembly process, and then send a third instruction to the central domain controller to switch the vehicle state to a state where the next vehicle assembly process can be carried out.

[0104] During actual use, after the diagnostic device detects that the software flashing process is completed, the above steps S18 to S22 are not executed. The diagnostic device can directly detect the next vehicle assembly process, determine the state that the vehicle needs to switch to next according to the next vehicle assembly process, and then send a third instruction to the central domain controller to switch the vehicle state, so that the vehicle state is switched to a state where the next vehicle assembly process can be carried out.

[0105] For example, if the next vehicle assembly process requires that the vehicle mode is factory mode and the battery power state is off, the diagnostic device sends a third instruction to the central controller. After receiving the third instruction, the central controller switches the vehicle mode to factory mode and the battery power state to off, and then executes the above-mentioned process from step S20 to step S22.

[0106] It should be understood that the size of the serial numbers of the steps in the above embodiments does not 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 embodiments of the present application.

[0107] Corresponding to the power management method for vehicles on the production line described in the above embodiment, Figure 4 A structural block diagram of a power management device for vehicles on a production line provided in an embodiment of the present application is shown. For ease of explanation, only the parts related to the embodiment of the present application are shown.

[0108] Reference Figure 4 The device 300 may include: a state detection module 310 and a charging control module 320 .

[0109] The state detection module 310 is used to detect the current state of the vehicle when the vehicle is in the assembly stage of the production line, and the current state of the vehicle is determined based on the vehicle assembly process that needs to be performed currently;
