Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] This application provides a method for updating vehicle software configuration. The executing entity can be an electronic device, such as the vehicle's infotainment system. The following description uses the vehicle infotainment system as the executing entity of the method. Figure 1 This is a flowchart illustrating the vehicle software configuration update method provided in an embodiment of this application. (Refer to...) Figure 1 The method may include: Step 110: Determine the vehicle's hardware steering mode; Step 120: If the vehicle's hardware steering mode is switched, verify whether the software steering mode of the currently activated software configuration of the vehicle matches the vehicle's current target hardware steering mode. Step 130: If the software steering mode of the currently activated software configuration of the vehicle does not match the target hardware steering mode, upgrade the first software configuration package to the second software configuration package; the first software configuration package is the software configuration package of the currently activated software configuration of the vehicle, and the software steering mode of the second software configuration package matches the target hardware steering mode. Step 140: Update the vehicle's software configuration based on the second software configuration package.

[0022] In step 110, the vehicle system can detect the vehicle's hardware steering mode in real time to determine whether the vehicle is in left-hand drive or right-hand drive mode.

[0023] In step 120, if the vehicle's hardware steering mode changes, for example, from left-hand drive to right-hand drive, the vehicle system can check whether the software steering mode of the currently activated software configuration matches the vehicle's current target hardware steering mode. If the software steering mode of the activated software configuration matches the vehicle's current target hardware steering mode, the current state can be maintained; if the software steering mode of the activated software configuration does not match the vehicle's current target hardware steering mode, the vehicle's software configuration needs to be updated.

[0024] In step 130, the vehicle system can upgrade the first software configuration package to a second software configuration package that matches the target hardware steering mode.

[0025] In step 140, the vehicle system can update the vehicle's software configuration based on the second software configuration package, so that the vehicle's software configuration matches the vehicle's current target hardware steering mode.

[0026] The vehicle software configuration update method provided in this application updates the vehicle software configuration by upgrading the vehicle's software configuration package when the vehicle's hardware steering mode is switched, resulting in a new software version. This new software version's software steering mode matches the vehicle's current target hardware steering mode, thereby achieving automatic updates to the vehicle software configuration after the vehicle's left and right steering hardware is switched. This reduces vehicle development costs, avoids the problem of software and hardware configuration fragmentation caused by the vehicle's hardware steering mode switch, reduces the safety risks caused by software and hardware configuration fragmentation, and improves user experience.

[0027] In some embodiments, the vehicle's software configuration includes at least one of a user interface configuration and a vehicle dynamics control system configuration.

[0028] User interface configuration mainly refers to the configuration of the human-computer interaction user interface, while vehicle dynamic control system configuration mainly refers to the relevant configurations for maintaining vehicle stability.

[0029] The vehicle software configuration update method provided in this application updates the user interface configuration and the vehicle dynamic control system configuration by upgrading the vehicle's software configuration package when the vehicle's hardware steering mode changes. This ensures that the updated software steering mode matches the vehicle's current target hardware steering mode, thereby achieving automatic updates to the vehicle software configuration after the vehicle's left and right steering hardware switches. This reduces vehicle development costs, avoids the problem of software and hardware configuration fragmentation caused by the vehicle's hardware steering switch, reduces the safety risks caused by software and hardware configuration fragmentation, and improves the user experience.

[0030] In some embodiments, updating the user interface configuration based on the second software configuration package includes: loading a target user interface template from the second software configuration package; matching the target user interface template with a target hardware rudder mode; rearranging the positions and visually rendering the user interface components based on the target user interface template, and adjusting the coordinate mapping logic of the virtual button positions of the user interface components so that the virtual button positions correspond to the user touch sensing areas; and adjusting the voice pop-up position and sound field channel weights of the voice interaction components in the user interface components based on the target user interface template.

[0031] The vehicle infotainment system can load a target user interface template from the second software configuration package. The target user interface template matches the target hardware steering pattern. The target user interface template defines not only the absolute positions of icons, controls, and information, but also their layout anchor point relationships. For example, in the left-hand drive template, the anchor points for the navigation bar, shortcut virtual buttons for frequently used settings (such as air conditioning and music), and the status information bar are set in the left half of the screen and slightly to the left of the center line; while in the right-hand drive template, the anchor points for these same elements are mirrored and set in the right half of the screen and slightly to the right of the center line.

[0032] The process of updating the user interface configuration of the vehicle's infotainment system is dynamic and real-time. When updating the user interface configuration, the system does not restart the entire infotainment system. Instead, it iterates through the view layers of all currently running applications and rearranges and visually renders all reconfigurable user interface components according to the new target user interface template rules. For example, the card-style menu on the main screen is shifted from the left side to the right; the slider and temperature display on the air conditioning control panel are moved from near the driver's left to near the driver's right; and the search box and menu buttons on the map navigation interface are moved from the upper left to the upper right. This adjustment ensures that all interactive hotspots are biased towards the new driver side, reducing the need for hand reach and eye movement during operation. After the interface layout switch, to ensure the accuracy of touch interaction, the coordinate mapping logic of the virtual button positions corresponding to different user interface components on the touchscreen is also recalibrated to ensure that the new virtual button positions on the screen correspond to the user's touch-sensitive area. For example, in right-hand drive mode, the touch-sensitive area of ​​a "HOME" button located in the upper right corner of the screen is limited to the display area of ​​the icon, avoiding accidental touches or touch malfunctions due to layout changes.

[0033] The vehicle's infotainment system will also be adapted to the voice interaction components. Specifically, the location of the voice interaction pop-up window will be adjusted from the front left of the cockpit to the front right. The weights of the sound field channels in the voice synthesis will also be adjusted accordingly. For example, in right-hand drive mode, the volume weight of the right speaker will be increased to create the auditory experience of the sound source coming from the driver's side, improving the intuitiveness of the interaction.

[0034] The vehicle software configuration update method provided in this application updates the user interface configuration by upgrading the vehicle's software configuration package when the vehicle's hardware steering mode changes. This ensures that the driver's side operation convenience and visual focus are always in the optimal position. Moreover, the entire dynamic adaptation process is completed within seconds, and the user cannot perceive the system delay. This achieves efficient, accurate, and user-friendly automatic adaptation of the user interface when the vehicle switches between left and right steering hardware, without requiring manual user intervention or system restart, thus improving the user experience.

[0035] In some embodiments, the vehicle dynamic control system configuration includes a vehicle braking force configuration; updating the vehicle braking force configuration based on a second software configuration package includes: obtaining a vehicle braking force distribution strategy from the second software configuration package and sending it to the vehicle's chassis domain controller, so that the chassis domain controller distributes the vehicle's braking force based on the braking force distribution strategy; wherein the braking force distribution strategy includes at least one of the vehicle's target braking force curve, a front and rear axle braking force distribution ratio correction coefficient, and a yaw rate control response threshold.

[0036] When a vehicle physically switches between left-hand drive and right-hand drive modes, not only does the user interface need to be adjusted, but the underlying vehicle dynamic control system must also be reconfigured. The most critical aspect is the braking force distribution strategy of the vehicle stability system (such as Electronic Stability Control (ESC) / Electronic Stability Program (ESP)). Traditional braking force distribution strategies are based on a fixed vehicle model and do not consider the potential impact of driver position changes on the vehicle's dynamic balance perception and actual center of gravity distribution. This application proactively adjusts the braking force distribution to adapt to the current hardware steering mode through software logic. In left-hand drive mode, the vehicle system uses a set of braking force distribution calibration parameters that are biased towards the left side. For example, during emergency braking or cornering, the target braking force weight on the left wheels (on the same side as the driver) is slightly increased to help counteract the asymmetric load tendency caused by the driver's weight being on the left, optimizing the vehicle's pitch and yaw stability. Similarly, when the vehicle system determines it is in right-hand drive mode, it automatically switches to another set of calibration parameters, adjusting the priority of braking force distribution to the right wheels.

[0037] Specifically, the vehicle's infotainment system can obtain the vehicle's braking force distribution strategy from the second software configuration package and send it to the vehicle's chassis domain controller. The adjustment of the braking force distribution strategy is not limited to simple left-right weight switching; its parameter set is pre-determined through bench testing and real-vehicle calibration, including target braking force curves for different steering modes, front-to-rear axle braking force distribution ratio correction coefficients, and yaw rate control response thresholds. All these parameters are transmitted from the infotainment system or gateway to the vehicle's chassis domain controller in the form of data frames via the Controller Area Network (CAN) bus, enabling the chassis domain controller to distribute the vehicle's braking force based on the braking force distribution strategy.

[0038] The vehicle software configuration update method provided in this application updates the vehicle braking configuration by upgrading the vehicle's software configuration package when the vehicle's hardware steering mode is switched. This makes the updated vehicle braking configuration conform to the driver's usage habits under the current target hardware steering mode, which can optimize the vehicle's pitch and yaw stability, improve driving safety, and optimize the user experience.

[0039] In some embodiments, the vehicle dynamic control system configuration includes vehicle attitude configuration; updating the vehicle attitude configuration based on a second software configuration package includes: obtaining a vehicle attitude adjustment strategy from the second software configuration package and sending it to the vehicle's chassis domain controller, so that the chassis domain controller adjusts the reference coordinate system of the target sensor based on the vehicle attitude adjustment strategy; the target sensor is used to collect vehicle attitude data.

[0040] To ensure control precision, the vehicle system also works in conjunction with target sensors such as inertial measurement units and wheel speed sensors to collect vehicle attitude data. Based on the identified hardware steering mode, the chassis domain controller performs software-level fine-tuning of the reference coordinate system of the target sensor signals to ensure that the vehicle system's judgment of vehicle attitude is consistent with the driver's actual position perception.

[0041] The vehicle software configuration update method provided in this application updates the vehicle attitude configuration by upgrading the vehicle's software configuration package when the vehicle's hardware steering mode is switched. This ensures that the updated vehicle attitude configuration conforms to the driver's usage habits under the current target hardware steering mode. By implementing the linkage between the braking force distribution strategy and the driver's position at the software level, it ensures that the vehicle can provide consistent and stable braking dynamic performance regardless of whether the steering wheel is on the left or right, thereby improving driving safety and user experience.

[0042] In some embodiments, upgrading a first software configuration package to a second software configuration package includes: obtaining a differential data packet for upgrading the first software configuration package to a second software configuration package; the differential data packet is determined based on the first software configuration package and a third software configuration package stored in a local configuration library or in the cloud; the software steering mode of the third software configuration package is matched with the target hardware steering mode; and the second software configuration package is generated based on the first software configuration package and the differential data packet.

[0043] The vehicle's infotainment system first attempts to load the complete software configuration package for the target hardware steering mode (e.g., right-hand drive), i.e., the third software configuration package, from the local configuration library. If it does not exist in the local configuration library or the version is incompatible, it will connect to the cloud server via the in-vehicle T-Box to query and download the corresponding third software configuration package. To improve update efficiency and reduce network bandwidth consumption, the vehicle's infotainment system prioritizes incremental update technology. This technology does not transmit the entire software package, but rather compares the differences between the old and new versions, downloading and applying only the differences. Furthermore, compression and verification technologies are used during data transmission to ensure the integrity and security of the data packets.

[0044] Specifically, the vehicle system first obtains the differential data packets of the first software configuration package and the third software configuration package, and then generates a second software configuration package based on the first software configuration package and the differential data packets, which is used to update the vehicle software configuration.

[0045] The vehicle software configuration update method provided in this application update the vehicle software configuration by incrementally updating the vehicle software configuration package when the vehicle's hardware steering mode changes, thereby improving update efficiency and optimizing user experience.

[0046] In some embodiments, determining the hardware steering mode of a vehicle includes: acquiring the positions of the vehicle's steering wheel and pedals; if the steering wheel and pedals are both located on the same side of the vehicle, determining the vehicle's hardware steering mode based on the location of the steering wheel and pedals.

[0047] The vehicle's infotainment system can determine in real time whether the steering wheel and pedal assembly are currently installed on the left or right side of the vehicle by reading electrical signals from preset wiring harness connectors (e.g., steering wheel ignition signals, pedal assembly ID codes) or dedicated position sensors (such as Hall effect sensors mounted on the left and right mounting bases of the dashboard), thereby determining the vehicle's hardware steering mode. When both the steering wheel and pedal assembly are installed on the left side of the vehicle, the vehicle is determined to be in left-hand drive mode; when both are installed on the right side, the vehicle is determined to be in right-hand drive mode.

[0048] The vehicle software configuration update method provided in this application determines the vehicle's hardware steering mode by judging the position of the steering wheel and pedals. This method can accurately identify the switching of the vehicle's hardware steering mode, facilitating timely updates to the vehicle's software configuration.

[0049] In some embodiments, the method for updating vehicle software configuration further includes: if updating the vehicle software configuration fails, when the vehicle system restarts, reverting the vehicle software configuration to the software configuration before the update; if it is not possible to revert to the software configuration before the update, entering a downgrade mode; the downgrade mode provides a basic driving interface.

[0050] To address potential anomalies during vehicle software configuration updates, such as power outages, corrupted local software images, or network connection timeouts leading to update failures, this method incorporates a multi-layered fault-tolerance mechanism. First, if the update process is unexpectedly interrupted, the vehicle's infotainment system will boot into a simplified recovery environment upon the next startup. This environment will diagnose the cause of the update failure and automatically attempt to roll back to the previously known and stable software version before the switch. If the rollback is successful, the system will boot normally and notify the user that the previous switch failed. If the rollback also fails, the system will enter a limited "degraded mode." In this mode, complex entertainment functions and customizable interfaces will be disabled, providing only a basic driving interface (such as displaying vehicle speed and remaining range) to ensure safe driving. It will also ensure that core actuators such as steer-by-wire and brake-by-wire can receive basic operating commands, allowing the user to drive the vehicle to a repair shop rather than experiencing complete malfunction.

[0051] In addition, throughout the entire update process, from initial hardware checks and user interaction to each step of the software update (including success, cancellation, or failure), the vehicle's infotainment system records everything in a dedicated log file stored in non-volatile memory. The log includes timestamps, hardware status snapshots, software version numbers, user operation records, and any error codes encountered. This log can be read by technicians via a diagnostic interface for subsequent fault localization and system optimization iterations, thus forming the basis for user interaction and error handling.

[0052] The vehicle software configuration update method provided in this application embodiment can cope with the failure of updating vehicle software configuration by setting a fault tolerance mechanism for vehicle software configuration. When updating vehicle software configuration fails and retracing the original vehicle software configuration also fails, the vehicle system only supports the basic driving interface that ensures the safe driving of the vehicle (such as displaying vehicle speed and remaining range), thereby allowing the user to drive the vehicle to a repair shop instead of being completely paralyzed, thus improving driving safety.

[0053] Based on the above description, the complete process of the vehicle software configuration update method provided in this application is as follows: The vehicle has pre-installed standard wiring harness connectors and mechanical mounting points in the driver's and passenger's seats of the upper body (i.e., the passenger compartment). The assemblies for the steering wheel, brake, and accelerator pedals integrate dedicated identification chips (such as EEPROMs storing component IDs and types) or a specific set of physical pins. When the steering wheel is installed into an interface on one side, the vehicle's infotainment system can read the identification information of that operating component through the circuit connection of that interface. The infotainment system has pre-stored logical rules; for example, if a component with the identification ID "LHD_Steering_Wheel" is installed in the left-side interface, it determines that the current mode is left-hand drive; if a component with the identification ID "RHD_Steering_Wheel" is installed in the right-side interface, it determines that the current mode is right-hand drive. This detection is performed in real time or during the power-on self-test phase. The infotainment system continuously listens for status messages from the body domain controller or directly from hardware interfaces (such as authentication signals from the steering wheel wiring harness connector). When the vehicle's infotainment system detects a shift in the physical steering wheel position from left-hand drive to right-hand drive, it receives a CAN signal or a dedicated hardware interrupt signal containing a "right-hand drive mode" identifier. Upon receiving this signal, or upon receiving a mode switch command initiated by the user through the infotainment interface, the system immediately initiates a software compatibility verification process.

[0054] The software compatibility verification process accesses a pre-stored database within the vehicle containing both left-hand drive and right-hand drive software configurations (this database can be stored in a specific partition of the vehicle's storage unit). It verifies whether the currently active software configuration (such as interface layout logic and chassis communication protocol version) matches the newly detected target hardware drive mode. If the verification result is a match, the status quo is maintained; if the verification result is a mismatch, the vehicle system will not automatically update the vehicle software configuration. Instead, it will first display a high-priority reminder dialog box on the vehicle's central control screen via the user interface. This dialog box clearly informs the user: "Hardware configuration has been changed to [right-hand drive / left-hand drive], but the current system software is in [left-hand drive / right-hand drive] mode. Do you want to switch the software configuration immediately to match?" To prevent accidental operation, the dialog box provides three touch-sensitive options: "Switch Now," "Cancel," and "View Help," accompanied by clear voice prompts to guide the user to confirm.

[0055] After the user confirms the switch, the software update and configuration switch phase begins. The vehicle system retrieves a software configuration package matching the target hardware steering mode from the local configuration library or the cloud. It then updates the software configuration package using incremental update technology. Each software configuration library is a complete software environment encapsulation, containing not only a driver-oriented user interface layout, virtual button positioning, voice interaction interface orientation, and menu logic, but also a set of specific parameters related to the chassis control domain, especially the braking force distribution strategy parameters concerning the difference between left and right steering wheels in the vehicle stability system.

[0056] During the software configuration switching and writing phase, a phased, domain-specific control strategy is employed to ensure safety. First, the vehicle's operating system's own display and interaction logic is updated; once completed, the new user interface takes effect immediately. Next, the vehicle system sends the new mode commands and related parameter sets (such as the braking force distribution curve for right-hand drive mode) to the chassis domain controller via the vehicle's CAN bus or in-vehicle Ethernet communication network. Upon receiving the commands, the vehicle stability system dynamically loads the new control parameters, completing the reconfiguration. Throughout the update process, for critical safety functions such as braking and steering, the vehicle system ensures the continuity of its control logic. For example, when writing new parameters, the original basic control strategy remains unchanged; switching to the new strategy only occurs after the parameter update takes effect, thus avoiding functional interruptions or loss of control during the update period.

[0057] Furthermore, at the user interface level, the vehicle's infotainment system retrieves the corresponding graphical configuration file from local storage. In left-hand drive mode, the main interface layout of the central control screen and commonly used virtual buttons (such as air conditioning, volume, and navigation shortcut settings) will be shifted to the left to ensure optimal visibility and touch convenience for the driver even when their body is slightly turned to the left of the vehicle's center line. Conversely, in right-hand drive mode, these interface elements are shifted to the right. Simultaneously, the voice interaction system's display interface is also adjusted. For example, in right-hand drive mode, the voice recognition beamforming pickup area is preferentially pointed to the right, and the voice feedback text box displayed on the screen is correspondingly positioned on the right half of the screen to align with the operational intuition of right-hand drive users in markets such as the Middle East and Southeast Asia. Software adaptation is not limited to the human-machine interface but also includes the vehicle's control domain. After completing its interface switching, the vehicle's infotainment system sends a signal message containing the current steering mode identifier (such as "LHD" or "RHD") to the chassis domain controller via the vehicle's high-speed CAN (Controller Area Network) bus. Upon receiving this message, the chassis domain controller adjusts the control parameters of the vehicle stability system accordingly. For example, during emergency braking or dynamic stability control, it fine-tunes the braking force distribution strategy of the left and right wheels based on the driver's position (left-hand drive or right-hand drive) to compensate for the differences in dynamic characteristics caused by changes in driver mass distribution, thereby maintaining optimal vehicle stability.

[0058] Simultaneously, during the update process, the vehicle's infotainment system interface switches to a full-screen progress display page. This page includes a dynamically updated progress bar, the name of the module currently being updated (e.g., "Updating dashboard display logic," "Synchronizing chassis stability system parameters"), and clear text prompts such as "Do not disconnect power, do not operate the vehicle." Throughout the update process, the vehicle's infotainment system primarily uses a separate, complete software image from local storage for overwriting or activation. It only attempts to connect to the cloud server when digital signature verification or obtaining the latest parameters is required. This approach minimizes network dependence and improves switching speed and reliability.

[0059] Once the update task is complete, the vehicle's infotainment system will send confirmation signals to each control domain and record the success status of this switchover event. Simultaneously, the infotainment system will update the currently active software configuration identifier to a new identifier consistent with the hardware status, establishing a baseline for the next verification. If an error occurs at any stage of the update process (such as download failure, write verification error, or domain controller unresponsiveness), the infotainment system will interrupt the process, roll back to the previous stable and usable software configuration, and issue a clear fault warning to the user through both the graphical interface and voice prompts, prompting the user to check the network connection or contact service support, thereby ensuring that the vehicle's basic driving functions remain available.

[0060] The vehicle software configuration update apparatus provided in this application will be described below. The vehicle software configuration update apparatus described below can be referred to in correspondence with the vehicle software configuration update method described above.

[0061] Figure 2 This is a schematic diagram of the vehicle software configuration update device provided in an embodiment of this application. (Refer to...) Figure 2 The vehicle software configuration update device provided in this application embodiment is applied to an in-vehicle infotainment system, and the device may include: The determination module 210 is used to determine the hardware steering mode of the vehicle; The verification module 220 is used to verify whether the software steering mode of the currently activated software configuration of the vehicle matches the current target hardware steering mode of the vehicle if the hardware steering mode of the vehicle is switched; the upgrade module 230 is used to upgrade the first software configuration package to the second software configuration package if the software steering mode of the currently activated software configuration of the vehicle does not match the target hardware steering mode; the first software configuration package is the software configuration package of the currently activated software configuration of the vehicle, and the software steering mode of the second software configuration package matches the target hardware steering mode; The update module 240 is used to update the software configuration of the vehicle based on the second software configuration package.

[0062] The vehicle software configuration update device provided in this application update the vehicle software configuration by upgrading the vehicle's software configuration package when the vehicle's hardware steering mode is switched, resulting in a new software version. This new software version's software steering mode matches the vehicle's current target hardware steering mode, thereby achieving automatic update of the vehicle software configuration after the vehicle's left and right steering hardware is switched.
