Description

Technical Field

[0001] This application belongs to the field of intelligent vehicle technology, and in particular relates to a power management method, device, vehicle and storage medium for vehicles on a production line. Background Technology

[0002] When a vehicle is generated, different assembly processes need to be set according to the vehicle assembly steps. When the vehicle is on the production line, it needs to be assembled according to the set assembly processes. For example, first install the battery, then flash the software program, and then test the windshield wipers, etc.

[0003] Currently, in order to improve the level of vehicle intelligence, vehicle functions are constantly being added. This has led to an increase in the number of assembly processes that require battery power while the vehicle is on the production line. For example, the software flashing process requires battery power. However, in pursuit of vehicle lightweighting, the capacity of vehicle batteries is gradually decreasing. During the assembly process on the production line, excessive power consumption by the assembly process leads to battery depletion. Once the battery is depleted, it cannot provide power for subsequent assembly processes that require battery power, and the vehicle cannot be assembled, affecting vehicle production efficiency.

The first instruction is generated by the diagnostic device based on the vehicle assembly process's state requirements for the vehicle after determining the current vehicle assembly process to be performed.

[0016] In one possible implementation of the first aspect, if the vehicle assembly process that the vehicle currently needs to perform is a software flashing process, the vehicle status indication in the first instruction includes the battery power status being on and the vehicle mode being factory mode.

[0020] After receiving the second instruction sent by the diagnostic device, based on the vehicle status indication in the second instruction, the power state of the battery is controlled to be off and the vehicle mode is controlled to be factory mode. 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.

[0038] As used in this application specification and the appended claims, the term "if" may be interpreted, depending on the context, as "when," "once," "in response to determination," or "in response to detection." Similarly, the phrase "if determined" or "if detected [the described condition or event]" may be interpreted, depending on the context, as "once determined," "in response to determination," "once detected [the described condition or event]," or "in response to detection [the described condition or event]."

[0039] Furthermore, in the description of this application and the appended claims, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0040] References to "one embodiment" or "some embodiments" in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0041] With the development of new energy vehicles, in order to better serve users, vehicle functions are constantly increasing, and the overall power consumption of the vehicle is also constantly increasing. In order to achieve vehicle lightweighting and meet the requirement of starting the engine without a battery, the capacity of the battery is gradually decreasing.

[0042] During the vehicle manufacturing process, the vehicle needs to complete various assembly processes on the production line, such as battery assembly, software program writing, and testing of seats and wipers.

[0043] Currently, the battery cannot be charged while the vehicle is on the production line, but some assembly processes require battery power (low voltage power) to be completed. For example, software flashing needs to be done when the power mode is ON. Due to the increased vehicle functionality, the overall assembly time on the production line increases, and battery power consumption increases. If the battery power is insufficient, the battery will be depleted during vehicle assembly, preventing the vehicle from completing all assembly processes and thus preventing it from rolling off the production line, resulting in reduced vehicle production efficiency.

[0044] To address the problem of insufficient battery power preventing the battery from supporting the entire vehicle assembly, the inventors devised the following solution from a power-saving perspective: In assembly processes where battery power is not required, the battery's power state can be manually switched to the OFF position; in assembly processes where battery power is required, the battery's power state can be manually switched to the ON position. However, this method, involving manual switching of the battery's power state, is not only cumbersome but may also lead to incorrect switching.

[0045] Starting with the idea of ​​supplementing power, the inventor came up with the following solution:

[0046] Option 1: Use the high-voltage system to charge the battery when the battery power mode is ON. However, since vehicles are generally in factory mode during the assembly stage on the production line, and the high-voltage system is not allowed to be powered when the battery power mode is ON, this method is not feasible.

[0047] Option 2: Modify the production line by adding charging equipment to charge the batteries. However, this method is not feasible due to its time-consuming and costly nature, and the disruption to vehicle production during the modification process.

[0048] Based on the above problems, the inventors proposed the method of this application, which sets the current state of the vehicle according to the vehicle state required for vehicle assembly when the vehicle is on the production line. 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 that the vehicle cannot be assembled and cannot be rolled off the production line due to the battery being depleted.

[0049] The power management method for vehicles on the production line according to embodiments of this application will be described in detail below.

[0050] Figure 1 A schematic flowchart of the power management method for vehicles on a production line provided in this application is shown, with reference to... Figure 1 The method is described in detail below:

[0051] S101, when the vehicle is in the production line assembly stage, the current state of the vehicle is detected, and the current state of the vehicle is determined based on the vehicle assembly process that needs to be performed at the moment.

[0052] In this embodiment, vehicle production involves a production line with different workstations. Different assembly processes are performed at different workstations, such as software writing workstations, coolant filling workstations, and vehicle equipment testing workstations. Vehicle equipment may include seats, wipers, air conditioning, etc. After the vehicle enters the assembly stage, the battery and wiring harness can be installed first. After installation, the battery powers the entire vehicle. Through the workstation layout, high-voltage system insulation testing is performed first, allowing the high-voltage system to be energized and ensuring electrical safety.

[0053] In this embodiment, different vehicle assembly processes may have different requirements for the vehicle's state. For example, during process A, the vehicle's power state needs to be set to the OFF state, which represents the state of the battery; during the software flashing process, the vehicle's power state needs to be set to the ON state.

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

[0055] In this embodiment, the vehicle assembly process that the vehicle needs to perform at the current time can be determined by the diagnostic equipment scanning the identification code on the workstation. Alternatively, it can be determined by the diagnostic equipment (in the cloud) based on the vehicle's location and current stage. After determining the vehicle assembly process that needs to be performed, the diagnostic equipment sends a diagnostic command to the vehicle, which includes the state that the vehicle needs to switch to. The vehicle then switches states according to the diagnostic command.

[0056] Specifically, after receiving the first instruction (diagnostic command) sent by the diagnostic device, the state of the vehicle is switched based on the state indication of the vehicle in the first instruction. The first instruction is generated by the diagnostic device based on the state requirements of the vehicle assembly process after determining the current vehicle assembly process to be performed.

[0057] As an example, after determining that the current vehicle assembly process to be performed is a software flashing process, the diagnostic equipment generates a first instruction. The vehicle status indication in the first instruction includes the battery power status being "on" and the vehicle mode being "factory mode." Upon receiving the first instruction from the diagnostic equipment, the vehicle, based on the vehicle status indication in the first instruction, controls the battery power status to switch to "on" and the vehicle mode to switch to "factory mode." The vehicle's status is then defined as "power on" and "vehicle mode is factory mode."

[0058] S102, if the current state of the vehicle meets the preset conditions, then control the high-voltage system in the vehicle to charge the battery, wherein the preset conditions indicate that the vehicle assembly process is in a stage that allows the high-voltage system to be started.

[0059] In this embodiment, the preset conditions are pre-set and are determined based on the vehicle state required for the vehicle assembly process that allows the high-voltage system to be started.

[0060] In this embodiment, the preset conditions may include a first condition, which includes the power state being off and the vehicle mode being factory mode.

[0061] The preset conditions may also include a second condition, which includes the power status being in the start state and the vehicle mode being non-factory mode.

[0062] In this embodiment, after determining that the vehicle's current state meets preset conditions, the low-voltage power management system sends a power replenishment request to the vehicle controller. This request instructs the vehicle controller to activate the power replenishment mode, enabling the high-voltage system in the vehicle to charge the battery. The high-voltage system includes a power battery, etc.

[0063] In another embodiment, if the current state of the vehicle does not meet the preset conditions, the high-voltage system in the vehicle is controlled to prevent charging of the battery.

[0064] For example, if the battery is powered on and the vehicle is in factory mode, the high-voltage system is not allowed to start for safety reasons. Therefore, if the vehicle is currently powered on and in factory mode, the high-voltage system is prohibited from charging the battery.

[0065] In this application, when a vehicle is in the assembly stage on the production line, its current state is detected. The current state is determined based on the vehicle assembly process that needs to be performed. If the current state of the vehicle meets preset conditions, the high-voltage system of the vehicle is controlled to charge the battery. This application can control the high-voltage system to charge the battery when the vehicle is in the assembly stage and its current state meets preset requirements. Compared to existing methods where the battery cannot be charged during the assembly stage, this application can charge the battery during the assembly stage, ensuring the battery's charge level and thus ensuring that the battery can better serve the assembly process. This application prevents vehicle assembly from being halted due to a depleted battery, allowing the vehicle to complete assembly as quickly as possible and improving vehicle production efficiency.

[0066] In one possible implementation, step S102 may further include:

[0067] If the current state of the vehicle meets the preset conditions, obtain the target assembly process that requires battery power among all remaining vehicle assembly processes.

[0068] Find the assembly time for each target assembly process. Calculate the sum of the assembly times for all target assembly processes to obtain the total power consumption time. Pre-set which vehicle assembly processes require battery power and the assembly time for each vehicle assembly process.

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

[0070] Calculate the difference between the estimated usage time and the total power consumption time. If the difference is greater than the preset value, it is determined that the battery has sufficient power 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 the 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. Then, it is determined whether to charge the battery, which not only ensures the completion of vehicle assembly, but also saves energy.

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

[0074] like Figure 2 As shown, specifically, after step S102, the above method may further include:

[0075] S201, Starting from controlling the high-voltage system in the vehicle to charge the battery, the continuous charging time of the battery is counted.

[0076] In this embodiment, the timing starts from the moment the battery begins charging, and the continuous charging time of the battery is recorded.

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

[0078] In this embodiment, the preset duration can be determined based on the charging performance of the battery. For example, if the maximum charging time of the battery is 5 hours, that is, the battery is fully charged after 5 hours of charging, then the preset duration can be set to 5 hours.

[0079] Alternatively, the preset duration can be determined based on the total assembly time of the vehicle, for example, the preset duration can be set to 1.5 hours.

[0080] In this embodiment, after the continuous charging time reaches the preset time, the low-voltage power 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 vehicle's state changes before the preset charging time is reached, and it is necessary to stop the high-voltage system from charging the battery, the timing will stop when charging the battery is stopped.

[0082] In this application, the continuous charging time of the battery is counted when the battery starts charging. Once the continuous charging time of the battery reaches the preset time, the charging of the battery is stopped, which satisfies the requirements for charging the battery and also saves energy.

[0083] In one possible implementation, if the current state of the vehicle does not meet the preset conditions, and 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 a timely manner.

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

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

[0086] After the software flashing process is completed, the diagnostic equipment can send a second command 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 factory mode based on the vehicle status indication in the second instruction. The second instruction is sent by the diagnostic device to the vehicle after 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 assembly is completed and the vehicle is no longer in the production line assembly stage, the vehicle can exit the factory mode. The low-voltage power management system in the vehicle can detect the remaining power of the battery and determine whether the high-voltage system needs to charge the battery based on the remaining power.

[0089] like Figure 3 As shown, in one possible implementation, the vehicle may include a central domain controller, a low-voltage power management system, and a vehicle controller. The method described below will be illustrated using a vehicle software flashing example.

[0090] S11, the diagnostic equipment detects that the current vehicle assembly process to be performed is the software flashing process.

[0091] S12, the diagnostic equipment 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. The first instruction includes the vehicle mode that needs to be switched to as factory mode and the power status of the battery as on.

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

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

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

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

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

[0097] S17. After receiving a request to prohibit charging, the vehicle controller controls the high-voltage system to be shut down to prevent the high-voltage system from charging the battery.

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

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

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

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

[0102] S22. After receiving a power replenishment request, the vehicle controller activates the high-voltage system to charge the battery.

[0103] In actual use, after step S22, the diagnostic device 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 that can proceed with the next vehicle assembly process.

[0104] In actual use, after the diagnostic equipment detects that the software flashing process is completed, steps S18 to S22 are not executed. The diagnostic equipment can directly 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 that can proceed to the next vehicle assembly process.

[0105] For example, if the next vehicle assembly process requires the vehicle mode to be factory mode and the battery power status to be off, the diagnostic equipment sends a third instruction to the central controller. After receiving the third instruction, the central controller switches the vehicle mode to factory mode and switches the battery power status to off, and then executes the above steps S20 to S22.

[0106] It should be understood that the sequence number of each step in the above embodiments does not imply 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 this application.

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

[0109] The status detection module 310 is used to detect the current status of the vehicle when the vehicle is in the production line assembly stage. The current status of the vehicle is determined based on the vehicle assembly process that needs to be performed at the moment.

[0110] The charging control module 320 is used to control the high-voltage system in the vehicle to charge the battery if the current state of the vehicle meets preset conditions, wherein the preset conditions indicate that the vehicle assembly process is in a stage that allows the high-voltage system to be started.

[0111] In one possible implementation, the current state of the vehicle includes the vehicle mode and the power state of the battery, and the preset conditions include a first condition, which includes the power state being off and the vehicle mode being factory mode.

[0117] In one possible implementation, the state detection module 310 can specifically be used for:

[0118] After receiving the first instruction sent by the diagnostic device, the vehicle's state is switched based on the vehicle's state indication in the first instruction. The first instruction is generated by the diagnostic device based on the vehicle assembly process's state requirements for the vehicle after determining the current vehicle assembly process to be performed.
