Figure 1 As shown, the method includes:

[0044] Step S101: In response to an upgrade request from a vehicle controller, obtain battery information of the vehicle.

[0046] Among them, the battery information of the vehicle is information that characterizes the state of the battery in the vehicle. Optionally, the information that characterizes the state of the battery in the vehicle includes, but is not limited to, remaining power, charging state, state of health (SOH), temperature and other information. Among them, the battery information includes high-voltage battery information and low-voltage battery information. Specifically, a high-voltage battery usually refers to a battery with a voltage of more than 200V. There are also claims that its voltage is usually between 300 and 400V. High-voltage batteries are one of the core components of electric vehicles and are used to store and provide the electrical energy required to drive the motor. Its characteristics include large capacity, long driving range and fast charging capabilities. It is the key to achieving efficient and long-distance driving for electric vehicles. A low-voltage battery refers to a battery with a voltage of about 12V, which is usually used to power the vehicle's auxiliary systems and electronic equipment.

[0047] Among them, this application does not limit the process of obtaining the battery information of the vehicle in response to the upgrade request of the vehicle controller. Optionally, in response to the upgrade request of the vehicle controller, the battery management system (BMS) of the vehicle can be communicated to obtain the battery information of the vehicle. Optionally, after obtaining the battery information of the vehicle, the obtained battery information can also be verified to ensure its accuracy. Optionally, the battery information can also be recorded in a log for subsequent analysis and troubleshooting.

[0048] Step S102: Determine and display a controller upgrade method of the vehicle controller according to the high-voltage battery information and the low-voltage battery information.

[0049] Specifically, according to the high-voltage battery information and the low-voltage battery information obtained in step S101, the controller upgrade mode of the vehicle controller can be determined and displayed. Among them, the controller upgrade mode indicates the power supply type when the vehicle controller is software upgraded. Optionally, the controller upgrade mode is a low-voltage upgrade mode or a high-voltage upgrade mode. The power supply type includes a high-voltage power supply type and a low-voltage power supply type. Among them, the power supply type indicated by the low-voltage upgrade mode when the vehicle controller connected to the vehicle bus is software upgraded is a low-voltage power supply type. The power supply type indicated by the high-voltage upgrade mode when the vehicle controller connected to the vehicle bus is software upgraded is a high-voltage power supply type.

[0050] Among them, the present application does not limit the process of displaying the upgrade method of the vehicle controller. Optionally, the upgrade method of the vehicle controller can be displayed in the operation log of the gateway. Optionally, the upgrade method of the vehicle controller can also be displayed in the user interface.

[0051] Among them, the present application does not limit the process of determining and displaying the controller upgrade method of the vehicle controller according to the high-voltage battery information and the low-voltage battery information. Based on the description of the battery information in step S101, the process of determining and displaying the controller upgrade method of the vehicle controller according to the high-voltage battery information and the low-voltage battery information corresponds to the information indicated by the high-voltage battery information and the low-voltage battery information. Optionally, if the information indicated by the high-voltage battery information and the low-voltage battery information is power information, the controller upgrade method of the vehicle controller can be determined and displayed according to the power information indicated by the high-voltage battery information and the low-voltage battery information.

[0052] Step S103: performing an upgrade process on the vehicle controller according to the controller upgrade mode and software upgrade package of the vehicle controller.

[0053] Specifically, the upgrade process of the vehicle controller may be performed according to the controller upgrade mode of the vehicle controller determined and displayed in step S102 and the software upgrade package included in the upgrade request of the vehicle controller.

[0054] The present application does not limit the process of upgrading the vehicle controller according to the controller upgrade mode and software upgrade package of the vehicle controller. The vehicle controller can be powered by the power supply type indicated by the controller upgrade mode when performing software upgrade on the vehicle controller, and then the upgrade package of the vehicle controller is sent to the corresponding vehicle controller to upgrade the vehicle controller. If the controller upgrade mode of the vehicle controller determined in step S102 is two modes, the above process is repeated twice based on different controller upgrade modes.

[0055] If all vehicle controllers in the vehicle have completed the upgrade process through the upgrade process described above, it is determined that the vehicle controllers of the entire vehicle have completed the upgrade process.

[0056] Optionally, after determining that the vehicle controller of the entire vehicle has completed the upgrade process, a prompt message indicating that the upgrade has been completed may be generated and presented.

[0057] Optionally, during the upgrade process described above, if one or more vehicle controllers fail to upgrade, a prompt message of upgrade failure can be generated and presented, wherein the prompt message of upgrade failure indicates the identifier of the vehicle controller that failed to upgrade, and the prompt message of upgrade failure also indicates the reason for the failure of the vehicle controller.

[0058] The vehicle controller upgrade method provided in the embodiment of the present application obtains the battery information of the vehicle in response to the upgrade request of the vehicle controller, determines and displays the controller upgrade mode of the vehicle controller according to the high-voltage battery information and the low-voltage battery information, and performs the upgrade process of the vehicle controller according to the controller upgrade mode and the software upgrade package of the vehicle controller, wherein before upgrading the vehicle control, the controller upgrade mode of the vehicle controller is first determined according to the battery information of the vehicle, thereby avoiding problems such as low power or power feeding caused by unreasonable setting of the controller upgrade mode, thereby improving the success rate of the vehicle controller upgrade and the user experience, wherein, in the process of determining the controller upgrade mode of the vehicle controller, the high-voltage battery information and the low-voltage battery information are considered more comprehensively, so that the determined controller upgrade mode is more reasonable, further improving the success rate of the vehicle controller upgrade and the user experience, based on the above description, the vehicle controller upgrade method provided in the embodiment of the present application improves the success rate of the vehicle controller upgrade and the user experience.

[0059] In a possible embodiment, the high-voltage battery information indicates the power of the high-voltage battery, and the low-voltage battery information indicates the power of the low-voltage battery, wherein the power of the high-voltage battery refers to the power stored in the high-voltage battery, and the power of the low-voltage battery refers to the power stored in the low-voltage battery.

[0060] Specifically, according to the description in step S102, the process of determining and displaying the controller upgrade method of the vehicle controller according to the high-voltage battery information and the low-voltage battery information corresponds to the information indicated by the battery information. Optionally, if the high-voltage battery information indicates the high-voltage battery power and the low-voltage battery information indicates the low-voltage battery power, the process of determining and displaying the controller upgrade method of the vehicle controller according to the high-voltage battery information and the low-voltage battery information may include: determining and displaying the controller upgrade method of the vehicle controller according to the high-voltage battery power indicated by the high-voltage battery information, and the low-voltage battery power indicated by the low-voltage battery information.

[0061] Among them, the present application does not limit the process of determining and displaying the controller upgrade method of the vehicle controller based on the high-voltage battery power indicated by the high-voltage battery information and the low-voltage battery power indicated by the low-voltage battery information.

[0062] Optionally, at least one low-voltage battery threshold and at least one high-voltage battery threshold may be set first, and then the controller upgrade mode of the vehicle controller may be determined and displayed according to the relationship between the high-voltage battery power indicated by the high-voltage battery information and the low-voltage battery power indicated by the low-voltage battery information and the set thresholds, so as to complete the upgrade of the vehicle controller.

[0063] Optionally, a pre-calibrated mapping relationship may be obtained, wherein the pre-calibrated mapping relationship indicates a correspondence between the low-voltage battery power, the high-voltage battery power, and the controller upgrade mode of the vehicle controller. The pre-calibrated mapping relationship corresponds to vehicle information such as vehicle model and vehicle configuration, wherein the vehicle configuration includes but is not limited to configuration information such as vehicle controller configuration and vehicle battery configuration.

[0064] Among them, among all the information indicated in the battery information, the battery power has the greatest impact on the upgrade process of the vehicle controller. Therefore, when determining and displaying the controller upgrade method of the vehicle controller based on the high-voltage battery information and the low-voltage battery information, if the high-voltage battery power indicated by the high-voltage battery information and the low-voltage battery power indicated by the low-voltage battery information are used, the controller upgrade method of the vehicle controller can be determined more accurately, further improving the success rate of the vehicle controller upgrade and the user experience.

[0065] In a possible embodiment, the vehicle controller upgrade method further includes: storing the acquired vehicle battery information, the determined controller upgrade method of the vehicle controller, and the result of the upgrade process in the operation log of the gateway.

[0066] The operation log of the gateway is used to store data during the operation of the gateway. Therefore, when the gateway executes the vehicle controller upgrade method provided by the present application, the battery information of the vehicle obtained during the upgrade process of the vehicle controller, the determined controller upgrade method of the vehicle controller, and the result of the upgrade process can be stored in the operation log of the gateway.

[0067] Figure 2 The process diagram of the vehicle controller upgrade method provided in this application is as follows Figure 2 ,like Figure 2 As shown, in this embodiment Figure 1 Based on the embodiment, a process of determining and displaying a controller upgrade mode of a vehicle controller according to the high-voltage battery power indicated by the high-voltage battery information and the low-voltage battery power indicated by the low-voltage battery information is described in detail. The method includes:

[0068] Step S201: If the high-voltage battery information indicates that the power level of the high-voltage battery is greater than or equal to a first high-voltage power level threshold, it is determined and displayed that the controller upgrade mode of the vehicle controller is a high-voltage upgrade mode.

[0069] Specifically, if the high-voltage battery information indicates that the power of the high-voltage battery is greater than or equal to the first high-voltage power threshold, it can be determined and displayed that the controller upgrade mode of the vehicle controller is a high-voltage upgrade mode.

[0070] The first high-voltage power threshold is a power threshold at which the pre-calibrated high-voltage battery can support all vehicle controllers in the vehicle to complete the controller upgrade process and still ensure the normal operation of the vehicle after the upgrade. The first high-voltage power threshold corresponds to vehicle information such as vehicle model and vehicle configuration.

[0071] Among them, if the high-voltage battery information indicates that the high-voltage battery power is greater than or equal to the first high-voltage power threshold, it is determined that no matter how much the low-voltage battery power indicated by the low-voltage battery is, the power of the high-voltage battery can support all vehicle controllers in the vehicle to complete the controller upgrade processing. Therefore, it can be determined and displayed that the controller upgrade method of the vehicle controller is the high-voltage upgrade method.

[0072] Step S202: If the high-voltage battery information indicates that the high-voltage battery power is less than or equal to the second high-voltage power threshold, and the low-voltage battery information indicates that the low-voltage battery power is greater than or equal to the first low-voltage power threshold, it is determined and displayed that the controller upgrade mode of the vehicle controller is the low-voltage upgrade mode.

[0073] Specifically, if the high-voltage battery information indicates that the high-voltage battery power is less than or equal to the second high-voltage power threshold, and the low-voltage battery information indicates that the low-voltage battery power is greater than or equal to the first low-voltage power threshold, it can be determined and displayed that the controller upgrade method of the vehicle controller is a low-voltage upgrade method.

[0074] The second high-voltage power threshold is a power threshold at which the pre-calibrated high-voltage battery cannot supply power to the vehicle controller during the upgrade process of the vehicle controller. If the power of the high-voltage battery is less than the second high-voltage power threshold, the normal operation of the vehicle cannot be guaranteed. The second high-voltage power threshold corresponds to vehicle information such as vehicle model and vehicle configuration. The first high-voltage power threshold is greater than the second high-voltage power threshold.

[0075] Among them, if the high-voltage battery information indicates that the high-voltage battery power is less than or equal to the second high-voltage power threshold, it is determined that the high-voltage battery cannot power the vehicle controller during the upgrade process of the vehicle controller. Therefore, it can be determined in combination with the low-voltage battery power indicated by the low-voltage battery information.

[0076] The first low-voltage power threshold is a power threshold at which the pre-calibrated low-voltage battery can support all vehicle controllers in the vehicle to complete the controller upgrade process, and can still ensure the normal operation of the vehicle after the upgrade. The first low-voltage power threshold corresponds to vehicle information such as vehicle model and vehicle configuration. If the low-voltage battery information indicates that the low-voltage battery power is greater than or equal to the first low-voltage power threshold, it is determined that no matter how much high-voltage battery power is indicated by the high-voltage battery, the power of the low-voltage battery can support all vehicle controllers in the vehicle to complete the controller upgrade process.

[0077] Therefore, based on the above description, when the high-voltage battery information indicates that the high-voltage battery power is less than or equal to the second high-voltage power threshold, if the low-voltage battery information indicates that the low-voltage battery power is greater than or equal to the first low-voltage power threshold, it can be determined and displayed that the controller upgrade method of the vehicle controller is a low-voltage upgrade method.

[0078] Step S203: If the high-voltage battery information indicates that the high-voltage battery power is less than the first high-voltage power threshold, and the low-voltage battery information indicates that the low-voltage battery power is less than or equal to the second low-voltage power threshold, then suspend the upgrade process of the vehicle controller.

[0079] Specifically, if the high-voltage battery information indicates that the high-voltage battery power is less than a first high-voltage power threshold, and the low-voltage battery information indicates that the low-voltage battery power is less than or equal to a second low-voltage power threshold, the upgrade process of the vehicle controller can be suspended.

[0080] The first high-voltage power threshold is greater than the second high-voltage power threshold. For the description of the first high-voltage power threshold, reference can be made to the description in step S201, which will not be repeated here. For the description of the second high-voltage power threshold, reference can be made to the description in step S202, which will not be repeated here.

[0081] The second low-voltage power threshold is a power threshold at which the pre-calibrated low-voltage battery cannot power the vehicle controller during the upgrade process of the vehicle controller. If the low-voltage battery power is less than the second low-voltage power threshold, the normal operation of the vehicle cannot be guaranteed. The second low-voltage power threshold corresponds to vehicle information such as vehicle model and vehicle configuration. The first low-voltage power threshold is greater than the second low-voltage power threshold.

[0082] Specifically, based on the description of the first high-voltage power threshold, when the high-voltage battery information indicates that the high-voltage battery power is less than the first high-voltage power threshold, it can be determined that the high-voltage battery cannot support all vehicle controllers in the vehicle to complete the controller upgrade process. At this time, the low-voltage battery power indicated by the low-voltage battery information is determined. If it is determined that the low-voltage battery information indicates that the low-voltage battery power is less than or equal to the second low-voltage power threshold, it is determined that the low-voltage battery cannot power the vehicle controller during the upgrade process of the vehicle controller. Therefore, based on the above description, it is determined that the high-voltage battery and the low-voltage battery cannot support all vehicle controllers in the vehicle to complete the controller upgrade process, and the upgrade process of the vehicle controller can be suspended.

[0083] Optionally, in response to an upgrade request from the next vehicle controller, if it is determined that the high-voltage battery and the low-voltage battery can support all vehicle controllers in the vehicle to complete the controller upgrade process, the upgrade process of the vehicle controller can be resumed.

[0084] Optionally, while the upgrade process of the vehicle controller is suspended, a prompt message indicating that the upgrade of the vehicle controller has failed can be generated and presented. Optionally, the prompt message indicating that the upgrade of the vehicle controller has failed generated and presented here can present the reason for the upgrade failure. Optionally, the prompt message indicating that the upgrade of the vehicle controller has failed generated and presented here can also include a recommended upgrade sequence for the vehicle controller, so that the user can select some vehicle controllers to be upgraded first, thereby improving the user's upgrade experience.

[0085] Among them, in the determination process described in step S201, if it is determined that the high-voltage battery can support all vehicle controllers in the vehicle to complete the controller upgrade process, then the controller upgrade methods of the vehicle controllers are determined and displayed to be high-voltage upgrade methods, which can improve the efficiency of the vehicle controller upgrade on the basis of improving the success rate of the vehicle controller upgrade and user experience. In the determination process described in step S202, if it is determined that the high-voltage battery cannot power the vehicle controller during the upgrade process of the vehicle controller, the low-voltage battery power indicated by the low-voltage battery information is confirmed, and if it is determined that the low-voltage battery can support all vehicle controllers in the vehicle to complete the controller upgrade process, then the controller upgrade methods of the vehicle controllers are determined and displayed to be low-voltage upgrade methods, which can further improve the success rate and user experience of the vehicle controller upgrade. In the determination process described in step S203, if it is determined that the high-voltage battery can only support some vehicle controllers in the vehicle to complete the controller upgrade process, but the low-voltage battery cannot power the vehicle controller during the upgrade process of the vehicle controller, then the upgrade process of the vehicle controller is suspended, which improves the safety and user experience of the vehicle controller upgrade. In summary, the efficiency, success rate, safety and user experience of the vehicle controller upgrade are improved.

[0086] Step S204: If the high-voltage battery information indicates that the high-voltage battery power is less than the first high-voltage power threshold and greater than the second high-voltage power threshold, and the low-voltage battery information indicates that the low-voltage battery power is greater than the second low-voltage power threshold, then according to the high-voltage battery power indicated by the high-voltage battery information, the controller upgrade mode of at least one vehicle controller is determined and displayed as the high-voltage upgrade mode.

[0087] Specifically, if the high-voltage battery information indicates that the high-voltage battery power is less than a first high-voltage power threshold and greater than a second high-voltage power threshold, and the low-voltage battery information indicates that the low-voltage battery power is greater than the second low-voltage power threshold, then the controller upgrade mode of at least one vehicle controller can be determined and displayed as a high-voltage upgrade mode based on the high-voltage battery power indicated by the high-voltage battery information.

[0088] For the description of the first high-voltage power threshold, please refer to the description in step S201, which will not be repeated here. For the description of the second high-voltage power threshold, please refer to the description in step S202, which will not be repeated here. For the description of the second low-voltage power threshold, please refer to the description in step S203, which will not be repeated here. The first high-voltage power threshold is greater than the second high-voltage power threshold.

[0089] Specifically, when the high-voltage battery information indicates that the high-voltage battery power is less than the first high-voltage power threshold and greater than the second high-voltage power threshold, it can be determined that the high-voltage battery can support some vehicle controllers in the vehicle to complete the controller upgrade process. On this basis, if the low-voltage battery information indicates that the low-voltage battery power is greater than the second low-voltage power threshold, it can be determined that the low-voltage battery can at least support some vehicle controllers in the vehicle to complete the controller upgrade process. Therefore, based on the above description, the controller upgrade mode of at least one vehicle controller can be determined and displayed as a high-voltage upgrade mode based on the high-voltage battery power indicated by the high-voltage battery information.

[0090] Among them, after the high-voltage battery supplies power for the upgrade process of the vehicle controller in the determined high-voltage upgrade mode, the remaining high-voltage battery power is greater than the second high-voltage power threshold. That is, when determining the number and type of vehicle controllers in the high-voltage upgrade mode according to the high-voltage battery power indicated by the high-voltage battery information, it is necessary to ensure that after the high-voltage battery supplies power for the upgrade process of the vehicle controller in the determined high-voltage upgrade mode, the remaining high-voltage battery power can still ensure the normal operation of the vehicle.

[0091] Step S205, when it is determined based on the low-voltage battery power indicated by the low-voltage battery information that the remaining low-voltage battery power after the low-voltage battery is powered for the upgrade processing of other vehicle controllers is greater than or equal to the second low-voltage power threshold, the controller upgrade mode of other vehicle controllers is determined and displayed as the low-voltage upgrade mode.

[0092] Specifically, as described in step S204, if the high-voltage battery information indicates that the high-voltage battery power is less than a first high-voltage power threshold and greater than a second high-voltage power threshold, and the low-voltage battery information indicates that the low-voltage battery power is greater than a second low-voltage power threshold, then according to the high-voltage battery power indicated by the high-voltage battery information, after the controller upgrade mode of at least one vehicle controller is determined to be the high-voltage upgrade mode, it can be determined according to the low-voltage battery power indicated by the low-voltage battery information whether the remaining low-voltage battery power after the low-voltage battery supplies power for the upgrade processing of other vehicle controllers is greater than or equal to the second low-voltage power threshold, that is, whether the remaining low-voltage battery power after the low-voltage battery completes the upgrade processing of other vehicle controllers can ensure the normal operation of the vehicle.

[0093] Among them, according to the low-voltage battery power indicated by the low-voltage battery information, it is determined that after the low-voltage battery supplies power for the upgrade processing of other vehicle controllers, the remaining low-voltage battery power is greater than or equal to the second low-voltage power threshold, that is, after the low-voltage battery completes the upgrade processing of other vehicle controllers, the remaining low-voltage battery power can ensure the normal operation of the vehicle, the controller upgrade mode of other vehicle controllers can be determined and displayed as a low-voltage upgrade mode.

[0094] Step S206: When it is determined based on the low-voltage battery power indicated by the low-voltage battery information that the remaining low-voltage battery power after the low-voltage battery supplies power for the upgrade process of other vehicle controllers is less than a second low-voltage power threshold, the upgrade process of the vehicle controller is suspended.

[0095] Specifically, as described in step S204, if the high-voltage battery information indicates that the high-voltage battery power is less than a first high-voltage power threshold and greater than a second high-voltage power threshold, and the low-voltage battery information indicates that the low-voltage battery power is greater than a second low-voltage power threshold, then according to the high-voltage battery power indicated by the high-voltage battery information, after the controller upgrade mode of at least one vehicle controller is determined to be the high-voltage upgrade mode, it can be determined according to the low-voltage battery power indicated by the low-voltage battery information whether the remaining low-voltage battery power after the low-voltage battery supplies power for the upgrade processing of other vehicle controllers is greater than or equal to the second low-voltage power threshold, that is, whether the remaining low-voltage battery power after the low-voltage battery completes the upgrade processing of other vehicle controllers can ensure the normal operation of the vehicle.

[0096] Among them, according to the low-voltage battery power indicated by the low-voltage battery information, it is determined that after the low-voltage battery has supplied power to the upgrade processing of other vehicle controllers, the remaining low-voltage battery power is less than the second low-voltage power threshold, that is, after the low-voltage battery has completed the upgrade processing of other vehicle controllers, when the remaining low-voltage battery power cannot guarantee the normal operation of the vehicle, the upgrade processing of the vehicle controller can be suspended.

[0097] Optionally, in response to an upgrade request from the next vehicle controller, if it is determined that the high-voltage battery and the low-voltage battery can support all vehicle controllers in the vehicle to complete the controller upgrade process, the upgrade process of the vehicle controller can be resumed.

[0098] Optionally, while the upgrade process of the vehicle controller is suspended, a prompt message indicating that the upgrade of the vehicle controller has failed can be generated and presented. Optionally, the prompt message indicating that the upgrade of the vehicle controller has failed generated and presented here can present the reason for the upgrade failure. Optionally, the prompt message indicating that the upgrade of the vehicle controller has failed generated and presented here can also include a recommended upgrade sequence for the vehicle controller, so that the user can select some vehicle controllers to be upgraded first, thereby improving the user's upgrade experience.

[0099] In the determination process described in step S204, if it is determined that the high-voltage battery cannot support all vehicle controllers in the vehicle to complete the controller upgrade process, but the low-voltage battery at least supports some vehicle controllers to complete the controller upgrade process, then the controller upgrade mode of at least one vehicle controller can be determined as the high-voltage upgrade mode according to the high-voltage battery power indicated by the high-voltage battery information, and then it is determined whether the low-voltage battery can support other vehicle controllers to complete the controller upgrade process. This further improves the success rate of vehicle controller upgrades and user experience.

[0100] Optionally, the vehicle controller is a power vehicle controller or a non-power vehicle controller. The power vehicle controller is a vehicle controller used to maintain the whole vehicle in a high-voltage control state. Optionally, the power controller includes but is not limited to at least one of a battery management controller, a motor controller, a whole vehicle controller, etc. The non-power vehicle controller is a vehicle controller other than the power vehicle controller.

[0101] Specifically, since the power vehicle controller needs to maintain the entire vehicle in a high-voltage control state, under normal circumstances, the power vehicle controller cannot be upgraded while maintaining the entire vehicle in a high-voltage control state. Therefore, the controller upgrade mode of the power vehicle control can be determined as a low-voltage upgrade mode, that is, in the process of determining the controller upgrade mode of some vehicle controllers as a low-voltage upgrade mode and determining the controller upgrade mode of other vehicle controllers as a high-voltage upgrade mode described in this step, the vehicle controllers determined as the low-voltage upgrade mode include the power vehicle controller.

[0102] Among them, in the process of determining the vehicle controller with a low-voltage upgrade method, the controller upgrade method of the power vehicle controller is preferentially determined as a low-voltage upgrade method, which can ensure the success rate of the power vehicle controller upgrade and further improve the success rate and user experience of the vehicle controller of the entire vehicle.

[0103] The embodiment of the present application provides a process for determining and displaying the controller upgrade mode of the vehicle controller according to the high-voltage battery power indicated by the high-voltage battery information and the low-voltage battery power indicated by the low-voltage battery information. If it is determined that the high-voltage battery can support all vehicle controllers in the vehicle to complete the controller upgrade process, then the controller upgrade modes of the vehicle controllers are determined and displayed to be high-voltage upgrade modes, which can improve the efficiency of the vehicle controller upgrade on the basis of improving the success rate of the vehicle controller upgrade and user experience. If it is determined that the high-voltage battery cannot power the vehicle controller during the upgrade process of the vehicle controller, the low-voltage battery power indicated by the low-voltage battery information is confirmed. If it is determined that the low-voltage battery can support all vehicle controllers in the vehicle to complete the controller upgrade process, then the controller upgrade modes of the vehicle controllers are determined and displayed to be low-voltage upgrade modes, which can further improve the success rate of the vehicle controller upgrade and user experience. If it is determined that the high-voltage battery can only support some vehicle controllers in the vehicle to complete the controller upgrade process, but the low-voltage battery cannot power the vehicle controller during the upgrade process of the vehicle controller, then the upgrade process of the vehicle controller is suspended, which improves the safety and user experience of the vehicle controller upgrade. If it is determined that the high-voltage battery cannot support all vehicle controllers in the vehicle to complete the controller upgrade process, but the low-voltage battery supports at least some vehicle controllers to complete the controller upgrade process, then the controller upgrade mode of at least one vehicle controller can be determined and displayed as a high-voltage upgrade mode based on the high-voltage battery power indicated by the high-voltage battery information, and then it is determined whether the low-voltage battery can support other vehicle controllers to complete the controller upgrade process. The success rate of vehicle controller upgrades and user experience are further improved. In summary of the above description, the process of determining and displaying the controller upgrade mode of a vehicle controller based on the high-voltage battery power indicated by the high-voltage battery information and the low-voltage battery power indicated by the low-voltage battery information provided in the embodiment of the present application further improves the success rate of vehicle controller upgrades and user experience.

[0104] Figure 3 The process diagram of the vehicle controller upgrade method provided in this application is as follows Figure 3 ,like Figure 3 As shown, in this embodiment Figure 1 or Figure 2 Based on the embodiment, a process of performing an upgrade process of a vehicle controller according to a controller upgrade mode and a software upgrade package of the vehicle controller is described in detail. The method includes:

[0105] Step S301: If it is determined that the controller upgrade mode of the vehicle controller is the high-voltage upgrade mode, the entire vehicle is controlled to enter a high-voltage control state, and a vehicle controller upgrade package is sent to the corresponding vehicle controller to perform an upgrade process on the vehicle controller.

[0106] Specifically, as in the determination process in step S201, if it is determined that the controller upgrade method of the vehicle controller is a high-voltage upgrade method, the entire vehicle is controlled to enter a high-voltage control state, and the vehicle controller upgrade package is sent to the corresponding vehicle controller to perform an upgrade process on the vehicle controller.

[0107] Among them, if it is determined that the controller upgrade method of the vehicle controller is all high-voltage upgrade method, then the whole vehicle can be controlled to enter a high-voltage control state so that all vehicle controllers meet the power supply type during software upgrade, that is, the high-voltage power supply type, thereby improving the efficiency of the vehicle controller upgrade.

[0108] Among them, based on the description of the power vehicle controller and the non-power vehicle controller in step S206, under normal circumstances, the power vehicle controller cannot be upgraded while maintaining the whole vehicle in a high-voltage control state. Therefore, the controller upgrade method of the power vehicle control needs to be determined as a low-voltage upgrade method. However, if, as described above, it is determined that the controller upgrade methods of the vehicle controllers are all high-voltage upgrade methods, that is, the controller upgrade method of the power vehicle controller is also a high-voltage upgrade method, then the processing method of the vehicle controller is as follows:

[0109] Optionally, the vehicle controller is a power vehicle controller or a non-power vehicle controller. The power vehicle controller includes a main partition and a secondary partition. Specifically, the power vehicle controller includes a main partition and a secondary partition, which are controller partitions set in the power vehicle controller, and both the main partition and the secondary partition can perform all the functions of the power vehicle controller. In some scenarios, the main partition can perform the main functions of the vehicle controller, the secondary partition can perform the secondary functions of the vehicle controller, and the main partition and the secondary partition can switch with each other. For example, during the upgrade process of the power vehicle controller, if the controller upgrade mode of the power vehicle controller is a high-voltage upgrade mode, the main partition can perform the function of maintaining the entire vehicle in a high-voltage control state, and the secondary partition can perform the function of controller upgrade.

[0110] Optionally, if the vehicle controller is a power vehicle controller or a non-power vehicle controller. The power vehicle controller includes a primary partition and a secondary partition. Then, the whole vehicle is controlled to enter a high-voltage control state, and the vehicle controller upgrade package is sent to the corresponding vehicle controller to perform the upgrade process of the vehicle controller, which may include:

[0111] First, a high voltage maintenance request is sent to the main partition of the power vehicle controller to control the entire vehicle to enter a high voltage control state, so that all vehicle controllers meet the power supply type during software upgrade.

[0112] Then, the vehicle controller upgrade package of the non-powered vehicle controller is sent to the corresponding non-powered vehicle controller to perform the upgrade process of the non-powered vehicle controller. The specific description of this step can refer to the description in step S301 and step S302, which will not be repeated here.

[0113] Secondly, the vehicle controller upgrade package of the power vehicle controller is sent to the corresponding secondary partition of the power vehicle controller to perform the upgrade process of the power vehicle controller. At this time, among the main partition and the secondary partition of the vehicle controller, only the secondary partition has completed the upgrade process.

[0114] Finally, after determining that all vehicle controllers have completed the upgrade process, a partition switching request is sent to the power vehicle controller, so that each power vehicle controller performs a partition switching process.

[0115] Specifically, after the partition switching process is performed, the secondary partition that has completed the upgrade process is switched to the primary partition, so that the partition that executes the power vehicle controller is the partition that has completed the upgrade.

[0116] Optionally, after the partition switching process is performed, the controller partition that becomes the secondary partition may be switched to perform the upgrade process, so that both partitions of the power vehicle controller are upgraded.

[0117] Among them, if it is determined that the controller upgrade mode of the vehicle controller is all high-voltage upgrade mode, then the whole vehicle can be controlled to enter the high-voltage control state so that all vehicle controllers meet the power supply type when performing software upgrades, that is, the high-voltage power supply type, thereby improving the efficiency of the vehicle controller upgrade. Among them, when upgrading the power vehicle controller under the high-voltage power supply type, the controller partition can be set to ensure that the controller upgrade is completed on the basis of maintaining the high-voltage state of the whole vehicle, thereby improving the success rate of the power vehicle controller upgrade, and further improving the success rate of the vehicle controller upgrade and user experience.

[0118] Step S302: If it is determined that the controller upgrade mode of the vehicle controller is the low-voltage upgrade mode, the entire vehicle is controlled to enter a low-voltage control state, and a vehicle controller upgrade package is sent to the corresponding vehicle controller to perform an upgrade process on the vehicle controller.

[0119] The software upgrade package includes a vehicle controller upgrade package. Specifically, the vehicle controller upgrade package is a compressed package for upgrading the corresponding vehicle controller. Optionally, when upgrading the vehicle controller, the vehicle controller upgrade package can be sent to the corresponding vehicle controller so that the vehicle controller that receives the vehicle controller upgrade package performs the upgrade process.

[0120] Specifically, as in the determination process in step S202, if it is determined that the controller upgrade method of the vehicle controller is a low-voltage upgrade method, the entire vehicle is controlled to enter a low-voltage control state, and the vehicle controller upgrade package is sent to the corresponding vehicle controller to perform an upgrade process on the vehicle controller.

[0121] Among them, if it is determined that the controller upgrade method of the vehicle controller is a low-voltage upgrade method, the entire vehicle can be controlled to enter a low-voltage control state so that all vehicle controllers meet the power supply type during software upgrade, that is, the low-voltage power supply type, thereby improving the efficiency of the vehicle controller upgrade.

[0122] Step S303: If the controller upgrade mode of at least one vehicle controller is determined to be the high-voltage upgrade mode, and the controller upgrade mode of other vehicle controllers is determined to be the low-voltage upgrade mode, the entire vehicle is first controlled to enter a low / high-voltage control state, and the vehicle controller upgrade package of the vehicle controller in the low / high-voltage upgrade mode is sent to the corresponding vehicle controller to perform the upgrade process of the vehicle controller in the low / high-voltage upgrade mode; after the upgrade process of the vehicle controller in the low / high-voltage upgrade mode is completed, the entire vehicle is controlled to enter another voltage control state, and the vehicle controller upgrade package of the vehicle controller in another controller upgrade mode is sent to the corresponding vehicle controller to perform the upgrade process of the vehicle controller in the other controller upgrade mode.

[0123] Specifically, as in the determination process in step S204 and step S205, if it is determined that the controller upgrade mode of at least one vehicle controller is determined to be a high-voltage upgrade mode, and the controller upgrade modes of other vehicle controllers are determined to be low-voltage upgrade modes, the whole vehicle is first controlled to enter a high-voltage control state, and the vehicle controller upgrade package of the vehicle controller in the high-voltage upgrade mode is sent to the corresponding vehicle controller to perform the upgrade process of the vehicle controller in the high-voltage upgrade mode; after the upgrade process of the vehicle controller in the high-voltage upgrade mode is completed, the whole vehicle is controlled to enter a low-voltage control state, and the vehicle controller upgrade package of the vehicle controller in the low-voltage upgrade mode is sent to the corresponding vehicle controller to perform the upgrade process of the vehicle controller in the low-voltage upgrade mode; wherein the vehicle controller is a power vehicle controller or a non-power vehicle controller. The vehicle controller determined to be in the low-voltage upgrade mode includes a power vehicle controller.

[0124] Alternatively, as in the determination process in step S204 and step S205, if it is determined that the controller upgrade mode of at least one vehicle controller is determined to be a high-voltage upgrade mode, and the controller upgrade modes of other vehicle controllers are determined to be low-voltage upgrade modes, the entire vehicle is first controlled to enter a low-voltage control state, and the vehicle controller upgrade package of the vehicle controller in the low-voltage upgrade mode is sent to the corresponding vehicle controller to perform the upgrade process of the vehicle controller in the low-voltage upgrade mode; after the upgrade process of the vehicle controller in the low-voltage upgrade mode is completed, the entire vehicle is controlled to enter a high-voltage control state, and the vehicle controller upgrade package of the vehicle controller in the high-voltage upgrade mode is sent to the corresponding vehicle controller to perform the upgrade process of the vehicle controller in the high-voltage upgrade mode; wherein the vehicle controller is a power vehicle controller or a non-power vehicle controller. The vehicle controller determined to be in the low-voltage upgrade mode includes a power vehicle controller.

[0125] Among them, the description of the power vehicle controller and the non-power vehicle controller can refer to the description in step S206, which will not be repeated here. Specifically, based on the description in step S206, the power vehicle controller is upgraded when controlling the entire vehicle to enter a low-voltage control state, which can ensure the success rate of the power vehicle controller upgrade and further improve the success rate of the vehicle controller upgrade and user experience.

[0126] Optionally, if it is determined that the vehicle controller in the high-voltage upgrade mode includes a power vehicle controller, the power vehicle controller in the high-voltage upgrade mode can be controlled to perform an upgrade process according to the upgrade process of the vehicle controller described in step S301.

[0127] Among them, if it is determined that the controller upgrade mode of at least one vehicle controller is determined to be a high-voltage upgrade mode, and the controller upgrade modes of other vehicle controllers are determined to be low-voltage upgrade modes, by controlling the entire vehicle to enter a low / high-voltage control state, all vehicle controllers in the low / high-voltage upgrade mode can meet the power supply type during software upgrade, that is, the low / high-voltage power supply type, and all vehicle controllers in the low / high-voltage upgrade mode can be controlled to upgrade, thereby improving the efficiency of vehicle controller upgrades.

[0128] The embodiment of the present application provides a process for upgrading the vehicle controller according to the controller upgrade mode and software upgrade package of the vehicle controller. If it is determined that the controller upgrade modes of the vehicle controllers are all high-voltage upgrade modes, the whole vehicle can be controlled to enter a high-voltage control state so that all vehicle controllers meet the power supply type during software upgrade, that is, the high-voltage power supply type, thereby improving the efficiency of the vehicle controller upgrade. Among them, when upgrading the power vehicle controller under the high-voltage power supply type, the controller partition can be set to ensure that the controller upgrade is completed on the basis of maintaining the high-voltage state of the whole vehicle, thereby improving the success rate of the power vehicle controller upgrade, and further improving the success rate of the vehicle controller upgrade and user experience. If it is determined that the controller upgrade mode of the vehicle controller is all low-voltage upgrade mode, then the whole vehicle can be controlled to enter a low-voltage control state so that all vehicle controllers meet the power supply type when performing software upgrades, that is, the low-voltage power supply type, thereby improving the efficiency of vehicle controller upgrades; if it is determined that the controller upgrade mode of at least one vehicle controller is determined to be a low-voltage upgrade mode, and the controller upgrade modes of other vehicle controllers are determined to be high-voltage upgrade modes, by controlling the whole vehicle to enter a low / high-voltage control state, all vehicle controllers in the low / high-voltage upgrade mode meet the power supply type when performing software upgrades, that is, the low / high-voltage power supply type, and controlling all vehicle controllers in the low / high-voltage upgrade mode to upgrade can improve the efficiency of vehicle controller upgrades. In summary, the efficiency, success rate, and user experience of vehicle controller upgrades are improved.

[0129] In a possible embodiment, in addition to determining the controller upgrade mode of the vehicle controller according to the high-voltage battery information and the low-voltage battery information described in step S102, the vehicle controller upgrade method further includes: first receiving a controller upgrade list sent by the cloud, and then performing an upgrade process on the vehicle controller according to the controller upgrade mode and software upgrade package of the vehicle controller indicated by the controller upgrade list.

[0130] The controller upgrade list indicates a control upgrade method of the vehicle controller. The present application does not limit the method of determining the controller upgrade list in the cloud, and it can be a pre-built list, a pre-built list updated at a preset update time, or a pre-built list updated after the configuration information of the vehicle is updated.

[0131] The process of performing the upgrade process of the vehicle controller according to the controller upgrade method and software upgrade package of the vehicle controller indicated in the controller upgrade list can be referred to. Figure 3 The description of the process of performing the upgrade process of the vehicle controller according to the controller upgrade method and software upgrade package of the vehicle controller in the illustrated embodiment will not be repeated here.

[0132] Optionally, since the controller upgrade method of the vehicle controller is indicated by the controller upgrade list, if the upgrade process of the vehicle controller is directly performed according to the controller upgrade method and software upgrade package of the vehicle controller indicated by the controller upgrade list, the low battery or power supply situation described in the prior art may occur. Therefore, the embodiment of the present application proposes that in the process of performing the upgrade process of the vehicle controller according to the controller upgrade method and software upgrade package of the vehicle controller indicated by the controller upgrade list, the controller upgrade list can be first verified according to the low-voltage battery information and the high-voltage battery information to ensure that each vehicle controller can operate normally after the upgrade process is completed according to the controller upgrade method of the vehicle controller indicated by the controller upgrade list.

[0133] Among them, the present application does not limit the process of upgrading the vehicle controller according to the controller upgrade method, low-voltage battery information, high-voltage battery information, and software upgrade package of the vehicle controller indicated by the controller upgrade list. Optionally, the process of upgrading the vehicle controller according to the controller upgrade method and software upgrade package of the vehicle controller indicated by the controller upgrade list may include: first verifying the controller upgrade list according to the low-voltage battery information and the high-voltage battery information. Specifically, the purpose of verifying the controller upgrade list according to the low-voltage battery information and the high-voltage battery information is to enable the battery power to support the vehicle controller to complete the upgrade of the vehicle controller according to the controller upgrade method indicated by the controller upgrade list. Among them, the process of verifying the controller upgrade list according to the low-voltage battery information and the high-voltage battery information can refer to Figure 2 In the illustrated embodiment, the process of determining the controller upgrade method of the vehicle controller based on the high-voltage battery power indicated by the high-voltage battery information and the low-voltage battery power indicated by the low-voltage battery information is similar in principle and will not be repeated here.

[0134] If the verification is passed, the vehicle controller is upgraded according to the controller upgrade method and software upgrade package of the vehicle controller indicated in the controller upgrade list.

[0135] Specifically, the upgrade process described here can be referred to Figure 3 The description in the illustrated embodiment will not be repeated here.

[0136] If the verification fails, the controller upgrade list is corrected according to the low-voltage battery information and the high-voltage battery information, and the vehicle controller is upgraded according to the controller upgrade method and software upgrade package of the vehicle controller indicated in the corrected controller upgrade list. Alternatively, if the verification fails, a prompt message indicating that the verification fails is generated and presented.

[0137] Specifically, the purpose of performing the upgrade process of the vehicle controller according to the controller upgrade method and software upgrade package of the vehicle controller indicated by the revised controller upgrade list is to enable the battery power to support the vehicle controller to complete the upgrade process of the vehicle controller according to the controller upgrade method indicated by the controller upgrade list. The process of performing the upgrade process of the vehicle controller according to the controller upgrade method and software upgrade package of the vehicle controller indicated by the revised controller upgrade list can refer to Figure 2 In the illustrated embodiment, the process of determining the controller upgrade method of the vehicle controller based on the high-voltage battery power indicated by the high-voltage battery information and the low-voltage battery power indicated by the low-voltage battery information is similar in principle and will not be repeated here.

[0138] Among them, in the process of upgrading the vehicle controller according to the controller upgrade method and software upgrade package of the vehicle controller indicated by the controller upgrade list, the vehicle controller is not upgraded directly according to the upgrade method of the vehicle controller indicated by the list. Instead, the controller upgrade list is verified according to the low-voltage battery information and the high-voltage battery information. This can improve the accuracy of the controller upgrade list, thereby improving the success rate of the vehicle controller upgrade and user experience.

[0139] Among them, before each vehicle controller update process is performed, the controller upgrade list is obtained from the cloud in real time, which can improve the real-time performance of the controller upgrade method and further improve the success rate of the vehicle controller upgrade and user experience.

[0140] In a possible embodiment, the controller upgrade list is determined by the cloud after acquiring the battery information based on the high-voltage battery information and the low-voltage battery information in the battery information.

[0141] Among them, the controller upgrade list is determined by the cloud after obtaining the battery information based on the high-voltage battery information and low-voltage battery information in the battery information. The specific process and effect can be referred to Figure 2 The description in the illustrated embodiment will not be repeated here.

[0142] Among them, before each vehicle controller update process, the controller upgrade list is obtained from the cloud in real time, which can improve the real-time performance of the controller upgrade method. The controller upgrade list is determined by the cloud after obtaining the battery information based on the high-voltage battery information and low-voltage battery information in the battery information. Therefore, it is more accurate, further improving the success rate of the vehicle controller upgrade and user experience.

[0143] Figure 4 A schematic diagram of the structure of the vehicle controller upgrade device provided in this application, such as Figure 4As shown, the vehicle controller upgrade device 40 provided in this embodiment includes:

[0144] The acquisition module 401 is used to acquire the battery information of the vehicle in response to the upgrade request of the vehicle controller; wherein the battery information includes high-voltage battery information and low-voltage battery information; the upgrade request of the vehicle controller includes a software upgrade package;

[0145] A determination module 402 is used to determine a controller upgrade mode of the vehicle controller according to the high-voltage battery information and the low-voltage battery information; wherein the controller upgrade mode indicates a power supply type when performing a software upgrade on the vehicle controller;

[0146] The upgrade module 403 is used to perform an upgrade process of the vehicle controller according to the controller upgrade mode and software upgrade package of the vehicle controller.
