Description

Technical Field

[0001] The present disclosure relates to the technical field of vehicles, and in particular, to a vehicle power-on method, device, equipment, medium, and vehicle. Background Art

[0002] Currently, during the vehicle startup process, usually after the body controller receives the startup signal, it directly wakes up all vehicle controllers, and then the domain controller controls the vehicle to start with high voltage, thereby realizing the startup of the vehicle.

[0003] However, from the moment all vehicle controllers are woken up to the completion of the vehicle's high-voltage startup, there is usually about 5 seconds during which all current consumption is provided by the low-voltage battery. Only after that will the high-voltage power of the power battery be converted into low-voltage power through a DC converter to provide low-voltage power for the entire vehicle.

[0004] Therefore, it is necessary for the low-voltage battery to have a strong discharge capacity to meet the vehicle's power consumption before the DC converter is connected. As a result, the requirement for the discharge capacity of the low-voltage battery is relatively high, increasing the cost of the battery. Summary of the Invention

[0005] To solve the above technical problems, the present disclosure provides a vehicle power-on method, device, equipment, medium, and vehicle.

[0008] Based on the health and temperature of the low-voltage battery, jointly determining whether the door unlocking request is normal; the health and temperature of the low-voltage battery are negatively correlated, and the higher the health of the low-voltage battery, the lower the temperature that the low-voltage battery can adapt to; if the determination is normal, controlling a preset controller to perform a high-voltage power-on operation, where the preset controller is a controller used to perform high-voltage power-on;

[0009] After determining that the high-voltage power-on is completed, waking up all vehicle controllers to complete the vehicle power-on.

[0014] Judge whether the high-voltage power-on is completed based on a preset judgment condition.

[0015] In some embodiments of the present disclosure, the preset judgment condition includes at least one of the output current of the DC converter being greater than zero, the input current of the DC converter being greater than zero, and the signal indicating that the high-voltage power-on of the battery management system is completed being set. Wherein, the output current and the input current of the DC converter are respectively determined based on the voltage value across the current sensor resistor, and the signal indicating that the high-voltage power-on of the battery management system is completed is determined based on the closed state of the main positive and main negative contactors of the power battery in the battery management system.

[0016] In some embodiments of the present disclosure, waking up the vehicle's entire vehicle controller includes:

[0017] Control the preset load of the vehicle to start and run the preset load, where the preset load is the load required to implement the preset personalized function.

[0018] The second aspect of the embodiments of the present disclosure provides a vehicle power-on device, and the device includes:

[0019] A request receiving module, configured to receive a door unlocking request sent by the user terminal;

[0020] A request recognition module, which judges whether the door unlocking request is normal based on the health and temperature of the low-voltage battery. The health and temperature of the low-voltage battery are negatively correlated. The higher the health of the low-voltage battery, the lower the temperature that the low-voltage battery can adapt to;

[0021] A first wake-up module, if the judgment result of the request recognition module is normal, controls the preset controller to perform a high-voltage power-on operation, where the preset controller is the controller used to perform the high-voltage power-on;

[0022] A judgment module, configured to judge whether the high-voltage power-on is completed based on a preset judgment condition;

[0023] A second wake-up module, configured to wake up the entire vehicle controller to complete the vehicle power-on after determining that the high-voltage power-on is completed.

[0024] In some embodiments of the present disclosure, the device further includes a signal sending module;

[0025] The signal sending module is configured to, after jointly judging that the door unlocking request is normal based on the health and temperature of the low-voltage battery, send a pre-power-on signal to the preset controller based on the body controller to wake up the preset controller.

When the computer program is executed by a processor, the vehicle power-on method according to the first aspect as described above is implemented.

[0031] The fifth aspect of the embodiments of the present disclosure provides a vehicle, including the electronic device according to the third aspect as described above.

[0032] The technical solutions provided by the embodiments of the present disclosure have the following advantages compared with the prior art:

[0033] The vehicle power-on method, device, equipment, medium and vehicle provided by the embodiments of the present disclosure can receive a door unlocking request sent by a user terminal. After receiving the door unlocking request, based on the health and temperature of the low-voltage battery, it is jointly determined whether the door unlocking request is normal; the health and temperature of the low-voltage battery are negatively correlated. The higher the health of the low-voltage battery, the lower the temperature that the low-voltage battery can adapt to; if it is determined to be normal, control a preset controller to perform a high-voltage power-on operation. The preset controller is a controller used to perform the high-voltage power-on. After determining that the high-voltage power-on is completed, wake up the vehicle controller to complete the vehicle power-on. Thus, during the vehicle startup process, the preset controller used to perform the high-voltage power-on operation can be woken up first. After controlling the preset controller to complete the high-voltage power-on, the vehicle controller is woken up to complete the high-voltage power-on. Since other controllers except the one performing the high-voltage power-on operation are not woken up during the process where the low-voltage battery is required to provide power before the high-voltage power-on, the number of controllers that the low-voltage battery needs to supply power to is reduced before the high-voltage power-on. Furthermore, the requirement for the discharge capacity of the low-voltage battery before the high-voltage power-on is reduced, that is, the capacity requirement of the low-voltage battery is reduced, and thus the cost of the low-voltage battery is reduced, and the service life of the low-voltage battery is improved.

It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0041] Many specific details are set forth in the following description in order to fully understand the present disclosure, but the present disclosure can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all the embodiments.

In addition, the method implementation manners may include additional steps and / or omit the steps shown. The scope of the present disclosure is not limited in this regard.

[0043] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover a non - exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0044] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise clearly specified in the context, it should be understood as "one or more".

[0045] Under normal circumstances, during the vehicle startup process, usually after the body controller receives the startup signal, it directly wakes up all vehicle controllers, and then the domain controller controls the high-voltage startup of the vehicle, thereby achieving the startup of the vehicle. However, from the moment all vehicle controllers are woken up to the completion of the vehicle's high-voltage startup, there is usually about 5 seconds during which the low-voltage battery provides all the current consumption. After that, the high-voltage power of the power battery is converted into low-voltage power through a DC converter to provide low-voltage power for the entire vehicle. Therefore, the low-voltage battery is required to have a strong discharge capacity to meet the vehicle's power consumption before the DC converter is connected, and thus the requirement for the discharge capacity of the low-voltage battery is relatively high, increasing the cost of the battery. To address this problem, the embodiments of the present disclosure provide a vehicle power-on method, which will be introduced below in conjunction with specific embodiments.

[0046] Figure 1 FIG. is a flowchart of a vehicle power-on method provided by an embodiment of the present disclosure. This method can be executed by a vehicle power-on device, which can be implemented in software and / or hardware, and can be configured in an electronic device. Specifically, the electronic device can include an in-vehicle terminal, or any device capable of processing the vehicle power-on method.

[0047] As Figure 1 shown, the vehicle power-on method provided by the embodiments of the present disclosure includes the following steps.

[0048] S110. Receive a door unlocking request sent by the user terminal.

[0049] In the embodiments of the present disclosure, the electronic device continuously receives the door unlocking request sent by the user terminal.

[0050] In the embodiments of the present disclosure, the door unlocking request can be that the user clicks the door unlocking button in the application software for controlling vehicle startup in the user terminal to send the door unlocking request to the electronic device; or it can be the door unlocking request sent by the user through the Bluetooth of the user terminal to the electronic device.

[0051] Among them, the door unlocking request includes vehicle identification, the position of the door to be unlocked, and the number of doors, etc. The door unlocking request can also include controlling the vehicle to power on without unlocking the door.

[0052] In the embodiments of the present disclosure, the electronic device can continuously receive the door unlocking request sent by the user terminal based on the body controller.

[0053] S120. Based on the health and temperature of the low-voltage battery, jointly determine whether the door unlocking request is normal.

[0054] In the embodiments of the present disclosure, the health state of the low-voltage battery is negatively correlated with the temperature. The higher the health state of the low-voltage battery, the lower the temperature that the low-voltage battery can adapt to.

[0055] In the embodiments of the present disclosure, after receiving the door unlocking request sent by the user terminal, the electronic device jointly determines whether the door unlocking request is normal based on the health state and temperature of the low-voltage battery. The health state of the low-voltage battery is negatively correlated with the temperature. The higher the health state of the low-voltage battery, the lower the temperature that the low-voltage battery can adapt to. The specific correlation between the health state and temperature of the low-voltage battery is shown in the following table:

[0056]

[0057] As can be seen from the above table, the health state of the low-voltage battery is negatively correlated with the temperature. The higher the health state of the low-voltage battery, the lower the temperature that the low-voltage battery can adapt to. The evaluation of the health state (SOH) of the low-voltage battery belongs to existing mature algorithms, such as the open-loop method based on the durability model, the closed-loop method based on the battery model, etc.

[0058] Specifically, after receiving the door unlocking request sent by the user terminal, the electronic device controls the body controller to identify the door unlocking requirement and performs the door unlocking operation based on the identification result. Among them, the specific implementation manner of performing the door unlocking operation is similar to the existing door unlocking method and will not be elaborated here.

[0059] S130. If it is determined to be normal, control the preset controller to perform the high-voltage power-on operation, where the preset controller is the controller used to perform the high-voltage power-on.

[0060] In the embodiments of the present disclosure, after the electronic device controls the body controller to perform the door unlocking operation, it monitors whether the door is unlocked successfully. After determining that the door is unlocked successfully, it controls the preset controller to perform the high-voltage power-on operation, where the preset controller is the controller used to perform the high-voltage power-on.

[0061] In the embodiments of the present disclosure, the preset controller may include a domain controller, a battery management system, and a DC converter; or it may include a controller used to perform the high-voltage power-on operation other than the domain controller, the battery management system, and the DC converter. The preset controller can be understood as the controller necessary to perform the high-voltage power-on. The required preset controller may be different depending on the vehicle configuration. Specifically, it can be determined and set according to the actual situation of the vehicle and will not be limited here.

[0062] Among them, the domain controller can be used for the control of the high-voltage power-on.

[0063] The battery management system can be used to receive the high-voltage power-on request, control the power battery contactor, monitor the battery cells, etc.

[0064] A DC converter can be used to convert the high-voltage power of a power battery into the low-voltage power required by a vehicle.

[0065] In an embodiment of the present disclosure, after the electronic device controls the body controller to perform a door unlocking operation, it monitors in real time whether the door unlocking is successful. After detecting that the door unlocking is successful, or while monitoring whether the door unlocking is successful, it performs a fault detection on a preset controller. After determining that the preset controller has no fault and the door unlocking is successful, it controls the preset controller to perform a high-voltage power-on operation. The preset controller is a controller used to perform the high-voltage power-on operation. The specific implementation manner of controlling the preset controller to perform the high-voltage power-on operation is similar to the existing vehicle high-voltage power-on implementation manner and will not be elaborated here.

[0066] In some embodiments of the present disclosure, the electronic device can, after determining that the door unlocking fails, feedback a notice of door unlocking failure to the user terminal so that the user can continue to send a door unlocking request for further door unlocking.

[0067] S140. After determining that the high-voltage power-on is completed, wake up the vehicle controller to complete the vehicle power-on.

[0068] In an embodiment of the present disclosure, after the electronic device determines that the high-voltage power-on is completed, it wakes up the vehicle controller to complete the vehicle power-on.

[0069] In an embodiment of the present disclosure, the vehicle controller refers to a controller other than the preset controller. For example, the vehicle controller can include a comfort load controller, etc.

[0070] In an embodiment of the present disclosure, the way to wake up the vehicle controller can be network wake-up or hardware signal wake-up, etc.

[0071] In an embodiment of the present disclosure, it is capable of receiving a door unlocking request sent by a client. After receiving the door unlocking request, it jointly determines whether the door unlocking request is normal based on the health and temperature of the low-voltage battery. The health and temperature of the low-voltage battery are negatively correlated. The higher the health of the low-voltage battery, the lower the temperature that the low-voltage battery can adapt to. If it is determined to be normal, it controls a preset controller to perform a high-voltage power-on operation. The preset controller is a controller used to perform the high-voltage power-on. After determining that the high-voltage power-on is completed, it wakes up the vehicle controller to complete the vehicle power-on. Thus, during the vehicle startup process, it can first wake up the preset controller used to perform the high-voltage power-on operation. After controlling the preset controller to complete the high-voltage power-on, it then wakes up the vehicle controller to complete the high-voltage power-on. Since during the process of requiring the low-voltage battery to provide power before the high-voltage power-on, it does not wake up other controllers except the one performing the high-voltage power-on operation, thereby reducing the controllers that the low-voltage battery needs to supply power to before the high-voltage power-on, and further reducing the requirement for the discharge capacity of the low-voltage battery before the high-voltage power-on, that is, reducing the capacity requirement of the low-voltage battery, and further reducing the cost of the low-voltage battery.

[0072] Based on the above embodiment of the present disclosure, according to Figure 1 the vehicle power-on method in, it can avoid waking up other controllers except the one performing the high-voltage power-on operation before the high-voltage power-on, thereby reducing the charge load of the low-voltage battery during the vehicle power-on process, and further increasing the service life of the low-voltage battery.

[0073] Based on the above embodiment of the present disclosure, after jointly determining that the door unlocking request is normal based on the health and temperature of the low-voltage battery, the vehicle power-on method may further include: sending a pre-power-on signal to the preset controller based on the body controller to wake up the preset controller.

[0074] In an embodiment of the present disclosure, the pre-power-on signal may be a signal used to wake up the preset controller, so that the preset controller performs a high-voltage power-on operation after receiving the pre-power-on signal.

[0075] Specifically, after jointly determining that the door unlocking request is normal based on the health and temperature of the low-voltage battery, and / or determining that the door unlocking is successful, the electronic device generates a pre-power-on signal, and sends the pre-power-on signal to the preset controller based on the body controller. After the preset controller receives the pre-power-on signal, it performs a high-voltage power-on operation.

[0076] Further, after controlling the preset controller to perform a high-voltage power-on operation, the vehicle power-on method may further include: determining whether the high-voltage power-on is completed based on a preset judgment condition.

[0077] In the embodiments of the present disclosure, the preset judgment conditions may include at least one of the output current of the DC converter being greater than zero, the input current of the DC converter being greater than zero, and the high-voltage completion signal of the battery management system being set, or may include the output current of the power battery being greater than zero, etc., which are not limited herein. Among them, the output current and input current of the DC converter are respectively determined based on the voltage value on the current sensor resistor, and the high-voltage completion signal of the battery management system is determined based on the closed state of the main positive and main negative contactors of the power battery in the battery management system.

[0078] In the embodiments of the present disclosure, the current sensor may be a Hall sensor, and the magnitudes of the output current and / or input current can be determined based on the change of the voltage value on the current sensor resistor.

[0079] When all the main positive and main negative contactors of the power battery are closed, it is determined that the high-voltage completion signal is set; otherwise, vice versa.

[0080] In the embodiments of the present disclosure, it is possible to determine that the power supply source of the low-voltage power supply system has changed from the low-voltage power supply at startup to the high-voltage power supply based on the output current of the DC converter, the input current of the DC converter, and the high-voltage completion signal of the battery management system.

[0081] Specifically, after the electronic device controls the preset controller to perform the high-voltage power-on operation, it monitors the high-voltage power-on situation in real time, and judges whether the high-voltage power-on is completed based on the preset judgment conditions. When it is monitored that the preset judgment conditions are met, it is determined that the high-voltage power-on is completed. If it is monitored that the preset judgment conditions are not met, it is determined that the high-voltage power-on is not completed, and the high-voltage power-on situation continues to be monitored.

[0082] In the embodiments of the present disclosure, by monitoring the high-voltage power-on situation in real time and then judging whether the high-voltage power-on is completed based on the preset judgment conditions, the accuracy of the high-voltage power-on monitoring is improved, so that after it is monitored that the high-voltage power-on is completed, the vehicle controller is woken up by timing, and the timeliness and accuracy of waking up the vehicle controller are improved.

[0083] In the embodiments of the present disclosure, waking up the vehicle controller may include: controlling the preset load of the vehicle to start to run the preset load, and the preset load is the load required to implement the preset personalized function.

[0084] In the embodiments of the present disclosure, the preset load may include various loads required to implement the preset personalized functions such as lighting control, seat heating / ventilation, steering wheel heating, audio control, seat welcome function, steering wheel memory, seat memory, vehicle atmosphere light, and driving mode.

[0085] In some embodiments of the present disclosure, an electronic device can send a wake-up signal to a preset load, so that the preset load starts and runs after receiving the wake-up signal.

[0086] In some other embodiments of the present disclosure, after determining that the high-voltage power-on is completed, the electronic device can control the switch of the preset load to switch from the off state to the on state, so that the preset load starts and runs.

[0087] In the embodiments of the present disclosure, after the high-voltage power-on is completed, it is possible to control the start of the preset load of the vehicle to run the preset load, so that the preset load can start and run in time after the high-voltage power-on is completed, so as to ensure that while reducing the capacity requirement of the low-voltage battery, thereby reducing the cost of the low-voltage battery and increasing the service life of the low-voltage battery, the user's needs can be met.

[0088] Figure 2 is a flowchart of another vehicle power-on method provided by the embodiments of the present disclosure. As Figure 2 shown, the vehicle power-on method includes the following steps:

[0089] S210. Receive a door unlock request sent by the user terminal.

[0090] S220. Based on the health and temperature of the low-voltage battery, jointly determine whether the door unlock request is normal.

[0091] S230. If the judgment is normal, send a pre-power-on signal to the preset controller based on the body controller to wake up the preset controller.

[0092] S240. Control the preset controller to perform a high-voltage power-on operation.

[0093] S250. Based on a preset judgment condition, judge whether the high-voltage power-on is completed.

[0094] S260. After determining that the high-voltage power-on is completed, wake up the vehicle controller to complete the vehicle power-on.

[0095] It should be noted that the specific implementation manners of steps S210-S260 are similar to those in the above method embodiments and will not be elaborated here.

[0096] In an embodiment of the present disclosure, a vehicle door unlocking request sent by a client can be received. After receiving the vehicle door unlocking request sent by the client, the body controller is controlled to perform a vehicle door unlocking operation based on the vehicle door unlocking request, and it is determined whether the vehicle door unlocking is successful. After determining that the vehicle door unlocking is successful, a pre-power-on signal is sent to a preset controller based on the body controller. After the preset controller receives the pre-power-on signal, it is awakened and controlled to perform a high-voltage power-on operation. After the preset controller performs the high-voltage power-on operation, it is determined whether the high-voltage power-on is completed based on a preset judgment condition. After determining that the high-voltage power-on is completed, the vehicle controller is awakened to complete vehicle power-on. Thus, during the vehicle startup process, the preset controller for performing the high-voltage power-on operation can be awakened first, and after controlling the preset controller to complete the high-voltage power-on, the vehicle controller is awakened to complete the high-voltage power-on, reducing the requirement for the discharge capacity of the low-voltage battery before the high-voltage power-on, that is, reducing the capacity requirement of the low-voltage battery, thereby reducing the cost of the low-voltage battery and increasing the service life of the low-voltage battery.

[0097] Figure 3 FIG. 4 is a schematic structural diagram of a vehicle power-on device provided by an embodiment of the present disclosure. The vehicle power-on device in the embodiment of the present disclosure can be disposed in an electronic device. The electronic device can be an in-vehicle terminal or any device capable of processing a vehicle power-on method, etc., which is not limited herein.

[0098] As Figure 3 shown in FIG. 5, the vehicle power-on device 300 may include a request receiving module 310, a request identifying module 320, a first wake-up module 330, a judgment module 340, and a second wake-up module 350.

[0099] The request receiving module 310 can be configured to receive a vehicle door unlocking request sent by a client.

[0100] The request identifying module 320 can be configured to determine whether the vehicle door unlocking request is normal based on the health and temperature of the low-voltage battery; the health and temperature of the low-voltage battery are negatively correlated. The higher the health of the low-voltage battery, the lower the temperature that the low-voltage battery can adapt to.

[0101] The first wake-up module 330 can be configured to, when the judgment result of the request identifying module is normal, control a preset controller to perform a high-voltage power-on operation. The preset controller is a controller for performing a high-voltage power-on.

[0102] The judgment module 340 can be configured to determine whether the high-voltage power-on is completed based on a preset judgment condition.

[0103] The second wake-up module 350 can be configured to, after determining that the high-voltage power-on is completed, wake up the vehicle controller to complete vehicle power-on.

[0104] In the embodiments of the present disclosure, it is capable of receiving a door unlocking request sent by a client. After receiving the door unlocking request, based on the health and temperature of the low-voltage battery, it jointly determines whether the door unlocking request is normal; the health and temperature of the low-voltage battery are negatively correlated. The higher the health of the low-voltage battery, the lower the temperature that the low-voltage battery can adapt to. If it is determined to be normal, it controls a preset controller to perform a high-voltage power-on operation. The preset controller is a controller used to perform the high-voltage power-on. After determining that the high-voltage power-on is completed, it wakes up the vehicle controller to complete the vehicle power-on. Thus, during the vehicle startup process, it can first wake up the preset controller used to perform the high-voltage power-on operation. After controlling the preset controller to complete the high-voltage power-on, it wakes up the vehicle controller to complete the high-voltage power-on. Since during the process of requiring the low-voltage battery to provide power before the high-voltage power-on, it does not wake up other controllers except the controller for performing the high-voltage power-on operation. In this way, before the high-voltage power-on, the number of controllers that the low-voltage battery needs to supply power to is reduced, thereby reducing the requirement for the discharge capacity of the low-voltage battery before the high-voltage power-on, that is, reducing the capacity requirement of the low-voltage battery, and further reducing the cost of the low-voltage battery.

[0105] In some embodiments of the present disclosure, the vehicle power-on device 300 may further include a signal sending module.

[0106] The signal sending module may be used to send a pre-power-on signal to the preset controller based on the body controller after jointly determining that the door unlocking request is normal based on the health and temperature of the low-voltage battery, so as to wake up the preset controller.

[0107] In some embodiments of the present disclosure, the preset judgment conditions include at least one of the output current of the DC converter being greater than zero, the input current of the DC converter being greater than zero, and the high-voltage completion signal of the battery management system being set. Among them, the output current and input current of the DC converter are respectively determined based on the voltage value on the current sensor resistor, and the high-voltage completion signal of the battery management system is determined based on the closed state of the main positive and main negative contactors of the power battery in the battery management system.

[0108] In some embodiments of the present disclosure, the second wake-up module 350 may specifically be used to control the startup of a preset load of the vehicle to run the preset load, and the preset load is a load required to implement a preset personalized function.

[0109] It should be noted that Figure 3 The illustrated vehicle power-on device 300 may execute each step in the above method embodiments and achieve each process and effect in the above method embodiments, which will not be elaborated here.

[0110] Figure 4 The structure diagram of an electronic device provided by the embodiments of the present disclosure is shown.

[0111] In the embodiments of the present disclosure, Figure 4 the electronic device shown may be a vehicle-mounted terminal or any device capable of being used for a vehicle power-on method, etc., which is not limited herein.

[0112] As Figure 4 shown, the electronic device may include a processor 410 and a memory 420 storing computer program instructions.
