Description

Technical Field

[0001] The present application relates to the field of vehicle control technology, and in particular to a software upgrading method, apparatus, computer equipment and storage medium. Background Art

[0002] With the continuous development of automotive technology, vehicles are becoming increasingly intelligent and connected. Over-the-air (OTA) software updates have become a crucial tool for vehicle maintenance and feature updates. In existing technologies, vehicle software updates primarily rely on a control unit connected to the vehicle's CAN bus or other communication interfaces to obtain real-time vehicle status information, such as ignition status and gear position, to determine whether the vehicle is in a suitable state for a software update.

[0003] However, in practical applications, relying solely on CAN bus signals or connected control units to obtain vehicle status information presents numerous problems. For one thing, CAN bus signals are susceptible to interference, especially in complex electromagnetic environments, such as when a vehicle is traveling near high-voltage power lines, passing near large electronic equipment, or experiencing malfunctions in the vehicle's own electronic equipment. This interference can cause the acquired vehicle status information to be erroneous or unstable, thus affecting accurate judgment of the vehicle's status. Furthermore, the control units connected to the CAN bus may themselves experience malfunctions, such as hardware failures, software vulnerabilities, or communication failures. These failures can also result in inaccurate vehicle status information, impacting the accuracy and security of software upgrades. Summary of the Invention

[0004] In view of this, the present application proposes a software upgrade method, apparatus, computer equipment and storage medium to solve the problem in the related art that inaccurate vehicle status information affects software upgrades.

[0043] The following describes exemplary embodiments of the present application in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. Instead, these embodiments are provided to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0044] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this application belongs.

[0045] The following describes the technical scenarios involved in the embodiments of this application.

[0046] OTA (Over-The-Air) is a remote wireless upgrade technology used in automobiles. It is one of the core technologies for automotive software updates, upgrading vehicle systems and functions via the internet. It mainly includes two types: SOTA (Software Over The Air) and FOTA (Firmware Over The Air). The former is similar to updating an app on a mobile phone, while the latter is equivalent to upgrading the smartphone system.

[0047] TBOX: A telematics box (TBOX) is a smart device installed in a vehicle, primarily used to enable communication and data transmission between the vehicle and external networks. Its main functions include remote monitoring and diagnosis, over-the-air (OTA) updates, vehicle positioning and tracking, and data collection and storage.

[0048] VCU: The vehicle control unit (VCU) is the core control unit of an electric or hybrid vehicle. It coordinates and manages the operation of various vehicle subsystems to ensure efficient and safe operation. It serves as the vehicle's "brain," collecting real-time sensor data, processing driving commands, and sending instructions to other controllers (such as the motor controller and battery management system) to implement functions such as power distribution, energy management, and fault diagnosis.

[0049] BMS: Battery Management System is an important control unit in new energy vehicles, mainly used to monitor and manage the status of the battery to ensure that the battery works under safe and efficient conditions.

[0050] MCU: Microcontroller Unit is an important control unit in new energy vehicles, mainly used to control the engine, transmission, braking system, instrument panel, etc.

[0051] SOC (State of Charge) is a key parameter in the battery management system (BMS), used to monitor the remaining battery charge and help users understand the vehicle's range.

[0052] According to an embodiment of the present application, an embodiment of a software upgrade method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0053] Example 1:

[0054] In this embodiment, a software upgrade method is provided, which can be used for a vehicle-mounted terminal (TBOX, Telematics Box). Figure 1 is a flowchart of a software upgrade method according to an embodiment of the present application, such as Figure 1 As shown, the process includes the following steps:

[0055] Step S101 , in response to a software upgrade request, determining whether the current vehicle state meets a first safety operating condition requirement.

[0056] Specifically, the software upgrade request can be understood as an OTA upgrade request. OTA (Over-The-Air) is a remote wireless upgrade technology used in automobiles to upgrade vehicle systems and functions via the internet. Vehicle status includes but is not limited to vehicle speed, gear status, and parking brake status.

[0057] More specifically, the software upgrade request is sent by the cloud server to the vehicle terminal of the current vehicle.

[0058] In some specific embodiments, the above step S101 includes step S1011:

[0059] Step S1011: If at least one of the following multiple first state requirements is not satisfied, then determining that the vehicle state of the current vehicle does not satisfy the first safety operating condition requirement; if all of the multiple first state requirements are satisfied, then determining that the vehicle state of the current vehicle satisfies the first safety operating condition requirement;

[0060] Among them, the multiple first status requirements include: whether the vehicle has completed the low-voltage power-on operation, whether the vehicle handbrake is in the pulled-up state, whether the vehicle gear is in neutral or parked state, and whether the vehicle speed is zero for several consecutive seconds (for example, the vehicle speed is 0 km / h for 5 seconds).

[0061] Step S102: When the current vehicle state meets the first safety operating condition requirement, a prompt message for software upgrade confirmation is sent to the display terminal.

[0062] Specifically, when the on-board terminal determines that the current vehicle status meets the first safety operating condition requirement, the vehicle terminal will send a software upgrade confirmation prompt message to the display terminal, so that the user / driver can perform a software upgrade confirmation operation (such as allowing the upgrade operation or rejecting the upgrade operation) on the display terminal according to the prompt message; when the display terminal receives the upgrade permission operation, it will send a software upgrade confirmation instruction to the on-board terminal; on the contrary, if the display terminal receives the upgrade rejection operation, the subsequent process will be stopped.

[0063] In some specific embodiments, the display terminal is a user terminal device or an instrument display device of the current vehicle.

[0064] In some specific embodiments, the above step S102 includes steps S1021 and S1022:

[0065] Step S1021: When the display terminal is the user terminal device, the software upgrade confirmation prompt information is sent to the cloud server, so that the cloud server forwards the software upgrade confirmation prompt information to the user terminal device, for example Figure 2 shown.

[0066] Specifically, the display terminal is the corresponding application in the user terminal device, that is, the APP terminal.

[0067] Step S1022: When the display terminal is the instrument display device, the prompt information of the software upgrade confirmation is sent to the instrument display device via the serial communication protocol, for example Figure 2 shown.

[0068] Specifically, the serial communication protocol includes but is not limited to the CAN bus.

[0069] Step S103, when receiving the software upgrade confirmation instruction from the display terminal, forwarding the software upgrade confirmation instruction to the vehicle controller, so that the vehicle controller responds to the software upgrade confirmation instruction and again determines whether the vehicle status of the current vehicle meets the second safety operating condition requirement.

[0070] Specifically, after receiving the software upgrade confirmation instruction from the display terminal, the on-board terminal will forward its software upgrade confirmation instruction to the vehicle controller (VCU, Vehicle Control Unit, VCU). After receiving the software upgrade confirmation instruction, the vehicle controller will again detect the vehicle status of the current vehicle to determine whether the vehicle status meets the second safety operating condition requirement; the second safety operating condition is different from the first safety operating condition requirement; when the vehicle status meets the second safety operating condition requirement, the vehicle controller will send an upgrade permission instruction to the on-board terminal; on the contrary, if the vehicle status does not meet the second safety operating condition requirement, the subsequent software upgrade process will not be executed, and the prompt information of the upgrade failure will be fed back to the user terminal device or the instrument display device of the current vehicle.

[0071] Step S104 , in response to the upgrade permission instruction from the vehicle controller, download the software upgrade package to perform software upgrade.

[0072] Specifically, the vehicle terminal downloads the software upgrade package from the cloud server; the vehicle terminal verifies the integrity of the software upgrade package (for example, using hash verification methods) to ensure that the downloaded upgrade package has not been tampered with or damaged; after passing the verification, the vehicle terminal begins to install the software upgrade package. During the installation process, various systems of the vehicle (such as the powertrain, chassis system, and body electronic system) are updated according to the instructions in the upgrade package.

[0073] In the embodiment of the present application, multiple judgments on the vehicle safety upgrade working conditions are made by the vehicle terminal TBOX and the vehicle controller VCU, reducing the reliance on a single judgment path and enhancing the security and stability of the OTA process. Preferably, by performing a precondition judgment on the user's confirmation of the upgrade operation, if the vehicle conditions are not met, the user does not need to confirm the upgrade operation, rather than being informed that the upgrade conditions are not met after confirming the upgrade operation, thereby improving the user's operating experience.

[0074] Example 2

[0075] Corresponding to the implementation of the above software upgrade method, the embodiment of the present application also provides a software upgrade method that can be used for the vehicle control unit (VCU) of the vehicle, such as Figure 3 As shown: The method includes:

[0076] Step S201: In response to a software upgrade confirmation instruction, determine whether the current vehicle state meets a second safety operating condition requirement.

[0077] Specifically, the software upgrade confirmation instruction is sent by the display terminal to the vehicle controller via the vehicle terminal in response to the upgrade confirmation operation;

[0078] More specifically, the upgrade confirmation operation is an operation performed by the user on the display terminal after the display terminal receives the prompt information of the software upgrade confirmation; the prompt information of the software upgrade confirmation is sent to the display terminal by the vehicle-mounted terminal in response to the software upgrade request when it is determined that the vehicle status of the current vehicle meets the first safety operating condition requirement.

[0079] Step S202: When the current vehicle state meets the second safety operating condition requirement, an upgrade permission instruction is sent to the vehicle-mounted terminal, so that the vehicle-mounted terminal responds to the upgrade permission instruction and downloads the software upgrade package to perform software upgrade.

[0080] In the above steps S201-S202, the vehicle terminal responds to the software upgrade request from the cloud server and determines whether the current vehicle state meets the first safety operating condition requirement. When the current vehicle state meets the first safety operating condition requirement, a prompt message for software upgrade confirmation is sent to the display terminal. The user / driver performs a software upgrade confirmation operation (e.g., allows the upgrade operation or rejects the upgrade operation) on the display terminal according to the prompt message. When the display terminal receives the software upgrade permission operation, it sends a software upgrade confirmation instruction to the vehicle terminal. On the contrary, if the display terminal receives the software upgrade rejection operation, the subsequent process is stopped.

[0081] After receiving the software upgrade confirmation instruction from the display terminal, the on-board terminal will forward its software upgrade confirmation instruction to the vehicle controller (VCU). After receiving the software upgrade confirmation instruction, the vehicle controller will again detect the vehicle status of the current vehicle to determine whether the vehicle status meets the second safety operating condition requirement; the second safety operating condition is different from the first safety operating condition requirement; when the vehicle status meets the second safety operating condition requirement, the vehicle controller will send an upgrade permission instruction to the on-board terminal; on the contrary, if the vehicle status does not meet the second safety operating condition requirement, the subsequent software upgrade process will not be executed, and the prompt information of the upgrade failure will be fed back to the user terminal device or the instrument display device of the current vehicle; after receiving the upgrade permission instruction, the on-board terminal will download the software upgrade package from the cloud server for software upgrade.

[0082] In some specific embodiments, the above step S201 includes step S2011:

[0083] Step S2011: If at least one of the following multiple second state requirements is not satisfied, determining that the vehicle state of the current vehicle does not satisfy the second safety operating condition requirement; if all of the multiple second state requirements are satisfied, determining that the vehicle state of the current vehicle satisfies the second safety operating condition requirement;

[0084] Among them, the multiple second status requirements include: whether the vehicle has completed the low-voltage power-on operation, whether the vehicle handbrake is in the pulled-up state, whether the vehicle gear is in neutral or parked state, whether the vehicle speed is zero for several consecutive seconds, the remaining battery power is greater than the preset power and the vehicle is in a non-charging state.

[0085] In the embodiment of the present application, multiple judgments on the vehicle safety upgrade working conditions are made by the vehicle terminal TBOX and the vehicle controller VCU, reducing the reliance on a single judgment path and enhancing the security and stability of the OTA process. Preferably, by performing a precondition judgment on the user's confirmation of the upgrade operation, if the vehicle conditions are not met, the user does not need to confirm the upgrade operation, rather than being informed that the upgrade conditions are not met after confirming the upgrade operation, thereby improving the user's operating experience.

[0091] The software upgrade module is used to download a software upgrade package to perform software upgrade in response to the upgrade permission instruction of the vehicle controller.
