Description
Technical Field
[0001] This application relates to the field of vehicle technology, and more specifically to a vehicle instrument cluster, configuration and upgrading method and system. Background Technology
[0002] The instrument panel in a vehicle is the core device for displaying the vehicle's operating status. It is mainly used to detect and provide feedback on the working status of various systems, enabling users to obtain information about the vehicle's status, such as mileage, speed, and fault information.

[0036] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0037] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.
[0038] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.
[0039] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.
[0040] See Figure 1 This is a schematic diagram illustrating an application scenario provided by an embodiment of this application. For example... Figure 1 As shown, the vehicle 100 includes an instrument panel 101, which is the core device for displaying the operating status of the vehicle 100. It is mainly used to detect and provide feedback on the working status of each system, so that the user can obtain the vehicle's status information.
[0041] It is understandable that the instrument 101 is used to output vehicle operating status information of the vehicle 100, such as mileage, speed, fault information, etc.
[0042] It should be pointed out that, Figure 1 This is merely an illustrative example of an application scenario involved in the embodiments of this application and should not be construed as limiting the scope of protection of this application. For example, the vehicles involved in the above application scenario can be fuel vehicles, pure electric vehicles, hybrid vehicles, etc., and the embodiments of this application do not specifically limit the type of vehicle. In addition, it can be understood that, in addition to Figure 1 Besides the instruments involved, there are other functional units or modules, which will not be described in detail in the embodiments of this application.
[0043] Currently, the design methods of instrument clusters in vehicles include: (1) using small-sized liquid crystal displays (LCDs) and pointer displays to reduce the number of hardware and costs; (2) displaying the vehicle's operating status information on the same LCD and using multi-function button programming to switch the displayed information, thereby reducing the number of buttons.
[0044] In practical applications, vehicles of the same model but with different powertrain configurations typically display different information on their instrument clusters. Therefore, the output signals for vehicles of the same model but different powertrain configurations usually differ. For example, a gasoline-powered vehicle might output specific signals such as fuel gauge, coolant temperature gauge, and average fuel consumption; a pure electric vehicle might output signals such as battery level, driving mode, and remaining range; and a hybrid vehicle might output signals such as power mode.
[0045] However, the instrument cluster designed using the above method can only output the operating status of a vehicle with one powertrain type. Therefore, this may result in low hardware reuse across instrument clusters of the same model with different powertrain configurations, thus increasing hardware costs.
[0046] To address the aforementioned issues, this application embodiment designs display circuits that match the powertrain configurations of different vehicles of the same model. Furthermore, the display circuits corresponding to different powertrain configurations of the same model are configured in the vehicle's instrument cluster, enabling the same instrument cluster to output vehicle operating status information for different powertrain configurations. Based on this, the hardware used by different display circuits to display the same vehicle operating status information is identical, resulting in a high degree of hardware reuse in the instrument cluster, thereby reducing hardware usage costs to some extent.
[0047] Specifically, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments.
[0048] See Figure 2This is a structural schematic diagram of a vehicle instrument cluster provided in an embodiment of this application. Figure 2 As shown, the vehicle instrument cluster includes a display module, which comprises at least two display circuits. Each display circuit controls the output of vehicle operating status information that matches the power type corresponding to the display circuit.
[0049] Understandably, vehicle powertrain types typically include gasoline-powered vehicles, hybrid vehicles, and pure electric vehicles. Different powertrain types usually require different information to be displayed on the display module. For example, gasoline-powered vehicles might display vehicle operating status information such as fuel gauge, coolant temperature gauge, and average fuel consumption; hybrid vehicles might display vehicle operating status information such as driving mode; and pure electric vehicles might display vehicle operating status information such as battery level, driving mode, and remaining range.
[0050] In this embodiment of the application, when it is necessary to output vehicle operating status information that matches the power type, the corresponding vehicle operating status information can be output through a display circuit that corresponds to the power type of the vehicle.
[0051] It should be noted that when the vehicle instrument cluster is installed on a vehicle, the display circuit in the display module is a display circuit corresponding to the vehicle's power type. For example, when the vehicle has a first power type, the display circuit in the display module is a first display circuit; when the vehicle has a second power type, the display circuit in the display module is a second display circuit. And so on. The embodiments in this application will not be described in detail here.
[0052] In addition, to improve hardware reusability, before designing display circuits that match different power types, it is usually necessary to clarify the signal requirements corresponding to different power types and the acquisition methods of each signal, thereby summarizing and organizing them into a structured functional list. The functional list includes, but is not limited to, input methods, signal sources, and power configurations.
[0053] For example, the function list is shown in Table 1. Regarding the power thermal management status indicator, the input method for gasoline and hybrid vehicles is CAN signal (LV0 & LV1), while the input method for pure electric vehicles is CAN signal (LV0); the signal is transmitted via message A and displayed as an icon. Regarding the turn signals, the input method for gasoline, hybrid, and pure electric vehicles is a hard-wired signal; the signal is transmitted via message B and displayed as an icon.
[0054] Table 1: It should be noted that the signal source and processing method for the same signal are usually the same for different power types of the same vehicle model. This provides a basis for hardware reuse in display circuits.
[0055] In this embodiment, after obtaining the functional list of the functional architecture, the signals are categorized according to the signal requirements of different power types. For example, according to the signal input method, they can be divided into CAN signal acquisition, hard-wired signal acquisition, button signals, and radar signal lights.
[0056] Furthermore, based on the signal requirements of vehicles with different power types, the maximum number of input / output interfaces is reserved, and the required chip memory is estimated for hardware selection.
[0057] For example, the corresponding display screens for different power types are shown in Table 2. Gasoline vehicles require a 3.5-inch segmented code display instrument cluster; hybrid vehicles require a 3.5-inch TFT display instrument cluster; and pure electric vehicles require a 3.5-inch segmented code display instrument cluster. It is understandable that a segmented code display can meet the information display needs of both gasoline and pure electric vehicles, and its usage cost is relatively low. Therefore, segmented code displays can be chosen for gasoline and pure electric vehicles. Hybrid vehicles have text display requirements; therefore, TFT displays can be chosen for hybrid vehicles.
[0058] Table 2: In the embodiments of this application, the same hardware is used for the same signal requirements, thereby improving the hardware reuse of the display circuit while meeting the signal requirements of vehicles with different power types.
[0059] In practical applications, in order to display vehicle operating status information, the vehicle instrument cluster needs to be able to collect the vehicle operating status number, thereby generating corresponding control commands to display the vehicle operating status information on the display module.
[0060] Therefore, in one possible implementation, the display circuit includes: a data acquisition module, a data processing module, and a display control module. The data acquisition module is used to acquire vehicle operating status signals that match the power type. The data processing module is used to generate display control commands corresponding to the vehicle operating status signals. The display control module is used to output vehicle operating status information corresponding to the display control commands.
[0061] See Figure 3 This is a schematic diagram of a display circuit provided in an embodiment of this application. Figure 3 As shown, the display circuit includes a power supply module, a CAN signal acquisition module, a hard-wired signal acquisition module, a data processing module, and a display control module.
[0062] Understandably, the power module provides stable and reliable power to the CAN signal acquisition module, hard-wired signal acquisition module, data processing module, and display control module. Both the CAN signal acquisition module and the hard-wired signal acquisition module are data acquisition modules. The CAN signal acquisition module acquires capability recovery indication signals and power management status indication signals via the CAN bus. The hard-wired signal acquisition module acquires gear position signals, battery charging signals, oil pressure alarm signals, handbrake status signals, brake fluid level signals, driver's door signals, other door signals, position signals, left turn signal signals, right turn signal signals, rear fog light signals, low beam headlight signals, high beam headlight signals, and other signal lights via hard wiring.
[0063] It should be noted that the data acquisition module is also used to acquire button signals and radar signals. As can be understood, button signals are signals generated by the user operating buttons on the vehicle. For example, when a user presses the seatbelt unlock button, the vehicle generates a seatbelt unlock signal. Of course, the data acquisition module in this embodiment can also be used to acquire other signals related to the vehicle's operating status, such as engine speed signals and motor power signals. This embodiment does not impose specific limitations on these aspects.
[0064] like Figure 3 As shown, the data acquisition module transmits the collected vehicle operating status signals to the data processing module. The data processing module can perform algorithmic calculations and analysis on the vehicle operating status signals, thereby generating display control commands corresponding to the vehicle operating status signals.
[0065] As can be understood, display control commands are used to instruct the display control module to perform corresponding display operations. For example, display control commands can be "left turn indicator light on", "right turn indicator light on", "engine malfunction alarm", "seatbelt reminder", or "driver's door not closed reminder", etc.
[0066] Furthermore, the data acquisition module transmits the display control command to the display control module, enabling the display control module to execute the display operation corresponding to the display control command.
[0067] For example, if the display control command is "Left turn indicator light on", the display control module will control the left turn indicator light to illuminate; if the display control command is "Right turn indicator light on", the display control module will control the right turn indicator light to illuminate; if the display control command is "Engine malfunction alarm", the display control module will control the engine malfunction indicator light to illuminate; if the display control command is "Driver's door not closed reminder", the display control module will control the driver's door indicator light to illuminate.
[0068] In addition, in this embodiment, the display control module includes: a buzzer control module, an indicator light control module, a motor control module, an LCD screen control module, and a backlight control module.
[0069] Understandably, the buzzer control module is used to emit alert sounds to remind users of important information or operational feedback; the indicator light control module is used to control whether the indicator lights are on, providing users with real-time feedback on the vehicle's operating status; the motor control module is used to drive the rotation of the pointer gauges, providing users with information on the vehicle's speed, RPM, or power; the LCD screen control module is used to drive the screen to display information such as the vehicle's battery level, oil pressure, and coolant temperature; and the backlight control module is used to adjust the brightness of the instrument panel's backlight to ensure that users can clearly read the data under different lighting conditions.
[0070] In practical applications, vehicles may need to output multiple vehicle operating status information simultaneously, such as engine fault information, vehicle speed information, and fuel level information. To ensure driving safety, in one possible implementation, the display control module is specifically used to: execute the display operation corresponding to each display control instruction according to the priority of each of the multiple display control instructions.
[0071] It is understandable that the priority of the displayed control commands is used to characterize the importance of the vehicle operating status information corresponding to the vehicle operating status signals. For example, the importance of critical emergency information (such as regulatory requirements information, fault information, etc.) > the importance of variable / optional information (such as vehicle speed, battery level, etc.) > the importance of auxiliary information (such as power, fuel level, etc.).
[0072] Therefore, in this embodiment, different priorities can be pre-assigned to display control commands corresponding to vehicle operating status information. When the display control module receives multiple display control commands, it can prioritize and execute the display operation corresponding to the display control command with the highest priority.
[0073] For example, when the display control module receives two display control commands, "engine malfunction alarm" and "seatbelt reminder", the display control module will prioritize illuminating the seatbelt indicator light because the "engine malfunction alarm" has a higher priority than the "seatbelt reminder".
[0074] It should be noted that, in the embodiments of this application, the display control module can support multi-task scheduling, that is, it can execute multiple display operations corresponding to multiple display control instructions at the same time, thereby improving the task processing speed of the display control module.
[0075] In this embodiment, the data acquisition module, data processing module, and display control module are each an independent module, with logical separation and clear functional positioning. This allows for modular reuse in display circuits corresponding to different power types, reducing the amount of code.
[0076] As mentioned above, vehicle powertrain types typically include gasoline-powered vehicles, hybrid vehicles, and pure electric vehicles. Therefore, in one possible implementation, at least two display circuits are included: a first display circuit, a second display circuit, and a third display circuit. The three display circuits will now be described in detail.
[0077] First display circuit: The first display circuit is used to control the output of vehicle operating status information that matches the type of fuel-powered vehicle. This vehicle status information, matching the type of fuel-powered vehicle, includes, but is not limited to, vehicle speed, engine speed, and fuel level.
[0078] See Figure 4A This is a schematic diagram of another display circuit provided in an embodiment of this application. Figure 4A As shown, the data acquisition module includes: a CAN IC and a hard-wired signal acquisition module, which is the left half near the instrument signal ground (GND); the data processing module is an MCU; the display control module includes an LCD (LCD control module), a MOTOR (motor drive module), a LAMOCONTROL (indicator light control module), and a SPEAKER (buzzer control module).
[0079] In this embodiment, the CAN IC and hard-wired signal acquisition module are used to acquire vehicle operating status signals corresponding to fuel vehicles; the microcontroller control unit or MCU is used to process vehicle operating status signals corresponding to fuel vehicles; and the display control module is used to output vehicle operating status data corresponding to fuel vehicles.
[0080] It should be noted that the MOTOR is used to drive the rotation of the speedometer and tachometer, providing users with information on vehicle speed and engine speed.
[0081] In addition, Figure 4A The diagram shows the connection method between the hard-wired signal acquisition module and the equipment related to the fuel-powered vehicle, specifically the left half near GND. Of course, in Figure 4A The diagram also shows the connection method between the hard-wired signal acquisition module and the MCU, as well as the connection methods between the MCU and the CAN IC, LCD, MOTOR, LAMO CONTROL, and SPEAKER, i.e., the right half away from GND.
[0082] Furthermore, when the vehicle's power type is a gasoline vehicle, relevant modules or devices can be connected to the display module according to the first display circuit, thereby enabling the vehicle to output vehicle status data information corresponding to a gasoline vehicle.
[0083] In this embodiment of the application, the first display circuit includes: a speedometer, a tachometer, an indicator light, a code break screen, a first button, and a second button.
[0084] As is understandable, the speedometer displays the vehicle's speed; the tachometer displays the engine's speed; and the display screen shows fixed numbers, symbols, or images. The first button is used to implement the first preset function, and the second button is used to implement the second preset function.
[0085] It should be noted that the first preset function and the second preset function are pre-set functions. For example, the first preset function and the second preset function can be any one of the following: switching and / or resetting the display mode of the vehicle mileage, switching and / or activating the vehicle's cruise control mode, adjusting tire pressure, etc. Those skilled in the art can set different first preset functions and second preset functions according to actual needs, and the comparison of the embodiments in this application does not impose specific limitations.
[0086] In this embodiment, the function corresponding to the button can be realized by a short press, so the user does not need to spend a long time pressing the button, which improves the user experience to a certain extent.
[0087] See Figure 4B This is a schematic diagram illustrating the effect of a vehicle instrument cluster device provided in an embodiment of this application. Figure 4B As shown, the instrument cluster includes: a speedometer (left half of the instrument cluster), a tachometer (right half of the instrument cluster), and a trip odometer (center of the instrument cluster). The first and second buttons are located at the bottom of the trip odometer. The first button is the TRIP button, and the second button is the SET button. The TRIP button can be used to switch and / or reset the vehicle's mileage display mode; the SET button can be used to switch and / or activate the vehicle's cruise control mode, or adjust tire pressure, etc.
[0088] In addition, Figure 4B The diagram shows indicator lights corresponding to various operating systems in a gasoline-powered vehicle, such as the battery level indicator, remaining range indicator, left turn indicator, right turn indicator, driver's side door indicator, fuel pressure indicator, brake system malfunction indicator, and ABS indicator. The display color and location of different types of indicator lights are usually different.
[0089] It should be noted that those skilled in the art can also set other indicator lights and their corresponding display colors and positions, and this application embodiment does not impose specific limitations on this.
[0090] To enable users to obtain important vehicle operating status information in a timely manner, this embodiment of the application can classify the vehicle operating status information according to its importance. Furthermore, the display method of the vehicle operating status information can be arranged according to field of vision requirements, thereby ensuring that steering wheel operation does not affect the display method of the vehicle operating status information.
[0091] For example, the importance of critical emergency information (such as regulatory requirements, fault information, etc.) is greater than that of variable / optional information (such as vehicle speed, battery level, etc.) which is greater than that of auxiliary information (such as power, fuel level, etc.). Fault information can be highlighted, such as by placing it in a more prominent position or displaying it in a larger font; auxiliary information can be de-emphasized, such as by placing it at the edge or displaying it in a smaller font.
[0092] Second display circuit: The second display circuit is used to control the output of vehicle operating status information matched to the hybrid vehicle type. It is understood that the vehicle status information matched to the hybrid vehicle type includes, but is not limited to, vehicle speed, power, fuel level, and battery level.
[0093] See Figure 5A This is a schematic diagram of another display circuit provided in an embodiment of this application. Figure 5A As shown, the data acquisition module includes: a CAN IC and a hard-wired signal acquisition module, which is the left half near GND; the data processing module is an MCU; the display control module includes an LCD (LCD control module), a MOTOR (motor drive module), a LAMO CONTROL (indicator light control module), and a SPEAKER (buzzer control module).
[0094] In this embodiment, the CAN IC and hard-wired signal acquisition module are used to acquire vehicle operating status signals corresponding to the hybrid vehicle; the microcontroller control unit or MCU is used to process the vehicle operating status signals corresponding to the hybrid vehicle; and the display control module is used to output vehicle operating status data corresponding to the hybrid vehicle.
[0095] It should be noted that the MOTOR is used to drive the rotation of the speedometer and power gauge, providing users with information on the vehicle's speed and power.
[0096] In addition, Figure 5A The diagram shows the connection method between the hardwired signal acquisition module and the hybrid vehicle-related equipment, specifically the left half near GND. Of course, in... Figure 5A The diagram also shows the connection method between the hard-wired signal acquisition module and the MCU, as well as the connection methods between the MCU and the CAN IC, LCD, MOTOR, LAMO CONTROL, and SPEAKER, i.e., the right half away from GND.
[0097] Furthermore, when the vehicle's power type is a hybrid vehicle, relevant modules or devices can be connected to the display module according to the second display circuit, thereby enabling the vehicle to output vehicle status data information corresponding to the hybrid vehicle.
[0098] In this embodiment of the application, the second display circuit includes: a speedometer, a power meter, an indicator light, a TFT screen, a second button, and a third button.
[0099] It is understandable that the speedometer displays the vehicle's speed; the power meter displays the vehicle's output power; and the TFT screen meets the requirements for displaying text information. The second button is used to implement the second preset function, and the third button is used to implement the third preset function.
[0100] It should be noted that the second and third preset functions are pre-set functions. For example, the second and third preset functions can be any one of switching and / or activating the vehicle's cruise control mode, adjusting tire pressure, adjusting brightness, etc. Those skilled in the art can set different second and third preset functions according to actual needs, and the comparison of the embodiments in this application does not impose specific limitations.
[0101] In this embodiment, the function corresponding to the button can be realized by a short press, so the user does not need to spend a long time pressing the button, which improves the user experience to a certain extent.
[0102] See Figure 5B This is a schematic diagram illustrating the effect of another vehicle instrument cluster device provided in an embodiment of this application. Figure 5B As shown, the instrument cluster includes: a speedometer (left half of the instrument cluster), a power gauge (right half of the instrument cluster), and a TFT screen (center of the instrument cluster). The second and third buttons are located at the bottom of the TFT screen. The second button is the SET button, and the third button is the brightness button. The SET button can be used to switch and / or activate the vehicle's cruise control mode, or adjust tire pressure, etc.; the brightness button is used to adjust the display brightness of the display module.
[0103] In addition, Figure 5B The diagram also shows indicator lights corresponding to the various systems related to the hybrid vehicle; for details regarding the indicator lights, please refer to the description in the above method embodiments. It should be noted that... Figure 5B The indicator lights shown include power mode indicator lights and indicator lights corresponding to various operating systems in fuel vehicles and pure electric vehicles, such as fuel level indicator lights, battery level indicator lights, and electric range indicator lights.
[0104] The third display circuit is used to control the output of vehicle operating status information that matches the type of pure electric vehicle. This vehicle status information, which matches the type of pure electric vehicle, includes, but is not limited to, vehicle speed, battery level, and remaining range.
[0105] See Figure 6A This is a schematic diagram of another display circuit provided in an embodiment of this application. Figure 6A As shown, the data acquisition module includes: a CAN IC and a hard-wired signal acquisition module, which is the left half near GND; the data processing module is a microcontroller control unit or MCU; the display control module includes LCD (LCD control module), MOTOR (motor drive module), LAMOCONTROL (indicator light control module) and SPEAKER (buzzer control module).
[0106] In this embodiment, the CAN IC and hard-wired signal acquisition module are used to acquire vehicle operating status signals corresponding to the pure electric vehicle; the microcontroller control unit or MCU is used to process the vehicle operating status signals corresponding to the pure electric vehicle; and the display control module is used to output vehicle operating status data corresponding to the pure electric vehicle.
[0107] It should be noted that the MOTOR is used to drive the rotation of the speedometer and power gauge, providing users with information on the vehicle's speed and power.
[0108] In addition, Figure 6A The diagram shows the connection method between the hard-wired signal acquisition module and the equipment related to the pure electric vehicle, specifically the left half near GND. Of course, in... Figure 6A The diagram also shows the connection method between the hard-wired signal acquisition module and the MCU, as well as the connection methods between the MCU and the CAN IC, LCD, MOTOR, LAMO CONTROL, and SPEAKER, i.e., the right half away from GND.
[0109] Furthermore, when the vehicle's power type is a pure electric vehicle, relevant modules or devices can be connected to the display module according to the third display circuit, so that the vehicle can output vehicle status data information corresponding to the pure electric vehicle.
[0110] In this embodiment of the application, the third display circuit includes: a speedometer, a power meter, an indicator light, a broken code screen, a second button, and a third button.
[0111] It is understood that the speedometer displays the vehicle's speed; the power meter displays the vehicle's output power; and the display screen shows fixed numbers, symbols, or images. The second button is used to implement a second preset function, and the third button is used to implement a third preset function.
[0112] It should be noted that the second and third preset functions are pre-set functions. For example, the second and third preset functions can be any one of switching and / or activating the vehicle's cruise control mode, adjusting tire pressure, adjusting brightness, etc. Those skilled in the art can set different second and third preset functions according to actual needs, and the comparison of the embodiments in this application does not impose specific limitations.
[0113] In this embodiment, the function corresponding to the button can be realized by a short press, so the user does not need to spend a long time pressing the button, which improves the user experience to a certain extent.
[0114] See Figure 6B This is a schematic diagram illustrating the effect of another vehicle instrument cluster device provided in an embodiment of this application. Figure 6B As shown, the instrument cluster includes: a speedometer (left half of the instrument cluster), a tachometer (right half of the instrument cluster), and a data entry display (center of the instrument cluster). The second and third buttons are located at the bottom of the data entry display. The second button is the SET button, and the third button is the brightness button. The SET button can be used to switch and / or activate the vehicle's cruise control mode, or adjust tire pressure, etc.; the brightness button is used to adjust the display module's brightness.
[0115] In addition, Figure 6B The diagram also shows indicator lights corresponding to various systems related to the pure electric vehicle; for details regarding the indicator lights, please refer to the description in the above method embodiments. It should be noted that... Figure 6B The indicator lights shown include those corresponding to various operating systems in a pure electric vehicle, such as battery level and remaining range indicators.
[0116] It should be noted that the hardware used in the three display circuits mentioned above to display the same operating status information is the same. For example, the same pin is used when collecting the vehicle's turn signal indication signal; the same indicator light is located in the same mold position on the instrument panel, etc.
[0117] In this embodiment, a display circuit matching the powertrain configuration is designed for vehicles of the same model but with different powertrain configurations. Furthermore, the display circuits corresponding to different powertrain configurations of the same model are configured in the vehicle's instrument cluster, enabling the same instrument cluster to output vehicle operating status information for different powertrain configurations. Based on this, the hardware used by different display circuits to display the same vehicle operating status information is identical, resulting in a high degree of hardware reuse in the instrument cluster, thereby reducing hardware usage costs to some extent.
[0118] In order to enable vehicles with different power types to display corresponding vehicle operating status information in the aforementioned vehicle instrument cluster, this application embodiment also provides a configuration method for the vehicle instrument cluster.
[0119] See Figure 7 This is a schematic flowchart illustrating a method for configuring a vehicle instrument cluster according to an embodiment of this application. Figure 7As shown, the configuration method is applied to an in-vehicle terminal, and the vehicle includes the vehicle instrument cluster device in the above method example, specifically including the following steps.
[0120] Step S701: Receive the triggered function configuration instruction.
[0121] It is understood that the function configuration instructions include configuration information that matches the vehicle's powertrain type. For example, powertrain mode, engine type, battery size, and steering function of the steering system. In this embodiment, the user can set configuration information that matches the vehicle's powertrain type on the configuration platform.
[0122] In practice, the configuration information is usually set by developers or after-sales personnel, eliminating the need for car owners to configure the relevant information themselves. This avoids complex online operations for car owners and improves the user experience to some extent. Step S702: Write the configuration information into the vehicle instrument cluster so that the vehicle instrument cluster can output vehicle operating status information that matches the vehicle power type.
[0123] In this embodiment, the vehicle-mounted terminal and the aforementioned vehicle instrument cluster are communicatively connected. When the vehicle-mounted terminal receives a function configuration command, it first parses the corresponding configuration information from the command and then writes the configuration information into the vehicle instrument cluster. This enables the instrument cluster to output vehicle operating status information that matches the vehicle's power type, achieving differentiated display.
[0124] In practical applications, upgrading the software related to a vehicle's instrument cluster usually requires manual updates, which can lead to high labor costs and low efficiency. Furthermore, it may require driving the vehicle to a dealership for the upgrade, potentially resulting in higher labor costs and a poor user experience.
[0125] See Figure 8 This is a flowchart illustrating a method for upgrading a vehicle instrument cluster provided in an embodiment of this application. Figure 8 As shown, the upgrade method is applied to an in-vehicle terminal, and the vehicle includes the vehicle instrument cluster as described in the above method example, specifically including the following steps.
[0126] Step S801: Establish a communication connection between the vehicle terminal and the car dealer's server.
[0127] In this embodiment, when the vehicle is in the OFF position, the in-vehicle terminal device can establish a communication connection with the vehicle manufacturer's server (e.g., OTA platform, service software, etc.) through the vehicle networking system T-BOX. Furthermore, it enables software maintenance related to the vehicle's instrument cluster.
[0128] Step S802: Receive the instrument cluster software upgrade package sent by the car dealer's server.
[0129] In this embodiment, developers or sales personnel can view the software version and vehicle conditions on the vehicle dealer's server to determine the instrument cluster software upgrade package. Once a communication connection is established between the in-vehicle terminal and the vehicle dealer's server, the developers or sales personnel can send the instrument cluster software upgrade package to the in-vehicle terminal through the vehicle dealer's server.
[0130] Furthermore, based on the communication connection with the car manufacturer's server, the in-vehicle terminal can receive the instrument cluster software upgrade package.
[0131] Step S803: Update the vehicle's instrument cluster according to the instrument cluster software upgrade package.
[0132] Understandably, once the vehicle terminal receives the instrument cluster software upgrade package sent by the car manufacturer's server, it can update the relevant software of the vehicle's instrument cluster device according to the upgrade package.
[0133] In this embodiment, remote communication between the vehicle terminal and the dealer's service center enables large-scale software upgrades of vehicle instrument clusters, quickly fixing defects and avoiding wasted manpower. Furthermore, eliminating the need to drive vehicles to dealerships for software upgrades reduces labor costs for owners, lowering after-sales maintenance expenses and improving user experience to some extent.
