[0002] As competition intensifies in the two-wheeled vehicle market, including electric vehicles and motorcycles, manufacturers typically produce a variety of configurations and models to meet diverse consumer needs and offer a wider range of choices in order to capture market share. Regarding instrument systems, different models often feature different software configurations to suit their unique functionalities and user interface requirements.

[0003] In related technologies, when certain car models become best-selling models, automakers will switch the instrument cluster systems of other models to match the best-selling models' systems to ensure other models also adapt to the current market. In this context, the reuse of instrument cluster systems across multiple models becomes increasingly important. However, switching instrument cluster systems between different models typically relies on OTA (Over-the-Air Technology), which uses cloud servers or local area network servers for remote instrument cluster system switching.

[0004] However, the remote instrument system switching method involves complex procedures and is inefficient due to limitations in the stability of external servers and network conditions, especially when a large number of instrument systems need to be switched simultaneously.

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings. Wherein, when the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0029] It should be understood that the embodiments described below do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. Depending on the context, the word "if" as used in this application can be interpreted as "when," "when," or "in response to determination."

[0032] In related technologies, when certain car models become best-selling models, automakers will switch the instrument cluster systems of other models, especially those in inventory, to the best-selling models to ensure that other models also adapt to the current market. In this context, the reuse of instrument cluster systems across multiple models becomes increasingly important. However, switching instrument cluster systems between different models typically relies on OTA (Over-the-Air Technology), which involves remotely switching instrument cluster systems via cloud servers or local area network servers.

[0033] However, the remote instrument system switching method involves complex procedures and is inefficient due to limitations in the stability of external servers and network conditions, especially when a large number of instrument systems need to be switched simultaneously.

[0034] This application improves the efficiency of instrument system switching by pre-storing instrument system software packages for several vehicle models in a preset storage area of ​​the instrument panel. When it is necessary to switch to the instrument system of a popular target vehicle model, the instrument system software of the popular target vehicle model can be directly obtained from the preset storage area for installation and switching, without relying on an external server to download the instrument system software package of the popular vehicle model.

[0035] The application scenarios of the vehicle instrument system switching method in this application include vehicles; the vehicle can be a two-wheeled vehicle such as a motorcycle or electric vehicle; the vehicle can also be a multi-wheeled vehicle such as a car, and this application does not impose any limitations. The vehicle includes an on-board instrument component, which can be an instrument control unit, such as a system-on-a-chip (SOC) or other device with processing and computing functions. The vehicle instrument system switching method of this application can be executed by the on-board instrument component, which can be implemented through software and / or hardware. The on-board instrument component can consist of two or more physical entities, or it can consist of a single physical entity. The hardware referred to by the on-board instrument component can essentially refer to computer equipment.

[0036] The following will be combined with the appendix Figures 1 to 6 This application provides a detailed description of the vehicle instrument system switching method provided in the embodiments.

[0037] Please see Figure 1 The vehicle instrument system switching method provided in this application embodiment is applied to vehicle instrument components. The preset storage area of ​​the vehicle instrument component stores several instrument system software packages corresponding to different vehicle models. The method includes the following steps:

[0038] Step S101: In response to the instrument system switching operation, display the vehicle model list; the vehicle model list includes several vehicle model identifiers.

[0039] In one embodiment, the in-vehicle instrument cluster includes an instrument control unit; the instrument control unit stores instrument system software packages corresponding to several vehicle models in a preset storage area.

[0040] In another embodiment, considering the variety of vehicle models and the large number of instrument system software packages, the amount of stored data will also increase. To reduce the storage pressure on the instrument control unit, the vehicle instrument component includes an instrument control unit and a memory. The memory has a preset storage area that stores several instrument system software packages corresponding to different vehicle models. The instrument control unit is connected to the memory, and the instrument control unit can retrieve the stored instrument system software packages from the memory.

[0041] It should be understood that the instrument system of this application includes an instrument interface and / or instrument firmware, etc. The instrument interface is the visual part through which the user interacts with the instrument, responsible for displaying the information collected and processed by the instrument system. The instrument firmware is a software program embedded in the instrument hardware, controlling the hardware operation and functional implementation of the instrument. It is understood that different vehicle models have different instrument interfaces and / or instrument firmware. Therefore, when switching instrument systems based on different vehicle models, this includes switching the instrument interface and / or switching the instrument firmware. In this case, switching the instrument interface refers to switching the interface layout and / or interface content, etc., and switching the instrument firmware refers to switching the user interaction performance and / or interaction logic, etc.

[0042] It should be understood that the instrument system switching in this application embodiment can be performed on vehicles that are not yet sold in inventory, or on vehicles that have already been sold. Whether the instrument system switching is performed on unsold vehicles in inventory or on vehicles that have already been sold, the instrument system switching operation is triggered by an engineer who initiates the instrument system program with preset permissions.

[0043] In an optional embodiment, the instrument system switching operation can be a power-on operation of the vehicle instrument components, that is, when the engineer starts the instrument system program with preset permissions to power on the vehicle instrument components, the vehicle model list is displayed.

[0044] In another optional embodiment, the instrument cluster includes an instrument cluster system switching control. The instrument cluster system switching operation can be triggered by a user, meaning that when an engineer activates the instrument cluster system with preset permissions, thereby triggering the instrument cluster system switching control, a vehicle model list is displayed. The in-vehicle instrument cluster includes a touchscreen; the instrument cluster system switching control can be a control on the instrument cluster touchscreen; or it can be a physical control located on the steering wheel or center console, etc.

[0045] In another optional embodiment, the instrument system switching operation can be a switching signal received by the on-board instrument component. For example, the on-board instrument component is communicatively connected to a server. When an engineer starts the instrument system program with preset permissions, the engineer sends a switching signal to the on-board instrument component through the server. When the on-board instrument receives the switching signal sent by the server, it displays a list of vehicle models. It should be understood that although the on-board instrument component in this embodiment also communicates remotely with the server to realize the instrument system switching, since the on-board instrument component and the server in this embodiment only transmit switching signals, and subsequently only transmit vehicle model identifiers on the server, compared with the method in related technologies that requires downloading the instrument system software package, the amount of information transmitted in this embodiment is small, and the impact on the switching efficiency of the instrument system is not significant.

[0046] Step S102: Obtain the target vehicle identifier selected in the vehicle list, and retrieve the target instrument system software package corresponding to the target vehicle identifier from the preset storage area.

[0047] In one embodiment, the in-vehicle instrument cluster includes a touchscreen; a list of vehicle models is displayed on the touchscreen, and in response to a user's triggering operation on one of the vehicle model identifiers on the touchscreen, the triggered vehicle model identifier is used as the target vehicle model identifier.

[0048] It is understandable that the vehicle model identifier and the corresponding instrument system software package are stored in the preset storage area. The vehicle instrument component can then query the target instrument system software package corresponding to the target vehicle model identifier based on the correspondence.

[0049] Step S103: Switch to the target instrument system according to the target instrument system software package.

[0050] Understandably, the vehicle instrument cluster installs the target instrument system based on the target instrument system software package, switches the system to the newly installed target instrument system, and then automatically restarts the vehicle to run the switched target instrument system.

[0051] This application embodiment pre-stores instrument system software packages corresponding to several vehicle models in a preset storage area of ​​the vehicle instrument component. Then, when responding to an instrument system switching operation, a vehicle model list is displayed. The vehicle model list includes several vehicle model identifiers. The target vehicle model identifier selected in the vehicle model list is obtained, and the software package corresponding to the target vehicle model identifier is retrieved from the preset storage area. At this time, there is no need to use an external server to download the system software package. The system can be switched to the target instrument system directly based on the stored target instrument system software package. The operation is simple and the efficiency of instrument system switching is improved.

[0052] Please see Figure 2 In one embodiment, the preset storage area also stores vehicle model configuration files; step S101, which involves displaying the vehicle model list in response to an instrument system switching operation, includes:

[0053] Step S1011: In response to the instrument system switching operation, obtain the vehicle configuration file.

[0054] The vehicle model configuration file records and describes information about several vehicle models, which may include model identification, model parameters, etc. Optionally, the vehicle model configuration file is associated with the instrument cluster system software packages corresponding to several vehicle models. That is, the number of vehicle models whose instrument cluster system software packages are stored in the preset storage area determines the number of vehicle models whose information is recorded and described in the vehicle model configuration file.

[0055] Step S1012: Display the vehicle model list based on the vehicle model configuration file.

[0056] The in-vehicle instrument cluster parses the vehicle model configuration file, extracts the vehicle model information, and obtains a list of vehicle models. For example, it extracts the model identifier from the configuration file to obtain a list of vehicles displaying each model identifier.

[0057] The vehicle list can be a drop-down menu, a list view, or a table, etc., and this application does not impose any restrictions.

[0058] This application embodiment displays a vehicle model list based on a vehicle model configuration file, which can improve the accuracy of the displayed vehicle model list and make it easier for users to browse and select the target vehicle model.

[0059] Please see Figure 3 In one embodiment, before the step of obtaining the vehicle model configuration file in response to the instrument system switching operation in step S1011, the following steps are included:

[0060] Step S111: In response to the file update operation, receive the updated vehicle configuration file.

[0061] It should be understood that during vehicle production, corresponding model configuration files are set for the various vehicle models produced, and these configuration files are then stored in a preset storage area. However, as the market changes, new models with different configurations may be produced, and these new models with different configurations may become best-selling models. Therefore, in order to better sell the vehicles in the previous inventory, it is necessary to update the model configuration files to update the stored instrument system software package and switch to the instrument system of the best-selling models.

[0062] Optionally, after the in-vehicle instrument cluster is powered on, a control will be displayed to indicate whether to update the file. In response to the user triggering the update control, the updated vehicle model configuration file will be retrieved from the server or an inserted external device.

[0063] Step S112: Replace the vehicle model configuration file in the preset storage area with the updated vehicle model configuration file.

[0064] This application embodiment receives the updated vehicle model configuration file and replaces the vehicle model configuration file in the preset storage area, so that the stored vehicle model configuration file can adapt to the needs of market vehicle models and facilitate users to switch to the target instrument system.

[0065] Please see Figure 4 In one embodiment, step S102, which involves obtaining the target vehicle identifier selected in the vehicle list and retrieving the target instrument system software package corresponding to the target vehicle identifier from a preset storage area, includes:

[0066] Step S1021: Determine whether the target instrument system software package is stored in the preset storage area.

[0067] Step S1022: When the target instrument system software package is not stored in the preset storage area, download the target instrument system software package to the preset storage area; retrieve the target instrument system software package from the preset storage area.

[0068] Understandably, when the updated vehicle configuration file includes newly added vehicles, the instrument cluster system software package corresponding to the newly added vehicles may not be available in the preset storage area. In this case, it is necessary to download the target instrument cluster system software package to the preset storage area and then retrieve the target instrument cluster system software package from the preset storage area.

[0069] In this embodiment of the application, when the target instrument system software package is not stored in the preset storage area, the target instrument system software package is downloaded to the preset storage area; obtaining the target instrument system software package from the preset storage area can ensure that the vehicle instrument switches to run the target instrument system.

[0070] Please see Figure 5 In one embodiment, step S1022, when the preset storage area does not store the target instrument system software package, includes the step of downloading the target instrument system software package to the preset storage area, which includes:

[0071] Step S1211: Establish a communication channel for connection with the server;

[0072] Step S1212: Based on the selected target vehicle model identifier, obtain the target instrument system software package corresponding to the target vehicle model identifier from the server through the communication channel, and store the target instrument system software package in the preset storage area.

[0073] Optionally, the vehicle instrument cluster can connect to the server via a local area network or public network to establish a communication channel with the server.

[0074] Optionally, the in-vehicle instrument cluster component sends the selected target vehicle model identifier to the server via a communication channel; the server locates the corresponding target instrument cluster system software package based on the target vehicle model identifier; in response to a switching command triggered by the engineer on the server, the server sends the target instrument cluster system software package to the in-vehicle instrument cluster component. The in-vehicle instrument cluster component reports the progress of acquiring the target instrument cluster system software package to the server at preset time intervals until the complete target instrument cluster system software package is acquired.

[0075] Based on the communication channel connected to the server, the embodiments of this application can conveniently obtain the target instrument system software package corresponding to the target vehicle model identifier from the server.

[0076] In another embodiment, step S1022, which involves downloading the target instrument system software package to the preset storage area when the preset storage area does not contain the target instrument system software package, includes:

[0077] Step S1221: When an external device is detected, the target instrument system software package corresponding to the target vehicle model identifier is obtained from the external device, and the target instrument system software package is stored in a preset storage area.

[0078] The external device can be a USB device, which stores the target instrument system software package corresponding to the target vehicle model identifier.

[0079] This application embodiment enables the direct and quick acquisition of the target instrument system software package corresponding to the target vehicle model identifier by using an inserted external device.

[0080] Please see Figure 6 In one embodiment, after step S112, which involves replacing the vehicle model configuration file in the preset storage area with the updated vehicle model configuration file, the process includes:

[0081] Step S1121: Determine the newly added vehicle model identifier based on the updated vehicle model configuration file and the previous vehicle model configuration file;

[0082] Step S1122: Download the instrument system software package corresponding to the newly added vehicle model identifier to the preset storage area.

[0083] It is understood that the method of downloading the instrument system software package corresponding to the newly added vehicle model identifier to the preset storage area is the same as the method of downloading the target instrument system software package mentioned above. It can be downloaded from the server or from the inserted external device, and this application does not impose any restrictions.

[0084] In this embodiment, after updating the vehicle model configuration file, the instrument system software package corresponding to the newly added vehicle model identifier is downloaded to a preset storage area in advance. Compared with downloading the corresponding target instrument system software package only after the user triggers the instrument system switch and determines the target vehicle model identifier, the download efficiency of the target instrument system and the switching efficiency of the instrument system can be improved.

[0087] The software package acquisition module 202 is used to acquire the target vehicle identifier selected in the vehicle list and retrieve the target instrument system software package corresponding to the target vehicle identifier from the preset storage area.

[0088] The system switching module 203 is used to switch to the target instrument system according to the target instrument system software package and run the switched target instrument system.
