[0038] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.

[0039] To make the objectives, technical solutions, and advantages of the present invention clearer, specific embodiments will be described below in conjunction with the accompanying drawings.

[0040] Figure 1 The following is a flowchart illustrating the implementation of a control method for a vehicle headlight maintenance mode according to an embodiment of the present invention. The execution subject of this method can be an electronic device with control functions, or it can be different devices, such as a headlight controller (Lighting Control Module, LCM) and a headlight driver (Lighting Control Drive, LCD), as detailed below:

[0041] Step 101: Upon receiving the maintenance mode activation command, obtain the vehicle status.

[0042] The maintenance mode can be turned on or off by the user via a virtual switch on the vehicle's HUT, and the current status of the maintenance mode is displayed.

[0043] In one embodiment, the maintenance mode activation command is generated by the HUT based on a received trigger signal, and is sent to the LCM as an event frame. The HUT sets the value of the corresponding maintenance mode switch signal status bit to a preset value indicating no action. Here, the trigger signal can be generated by the user clicking the virtual switch corresponding to maintenance mode activation on the HUT. By assigning values ​​to the maintenance mode switch signal status bits, corresponding maintenance mode activation commands, maintenance mode deactivation commands, and no-action states can be generated. For example, the maintenance mode activation command can be LightFixModSwt = 0x2:Open, the maintenance mode deactivation command can be LightFixModSwt = 0x1:Close, and no action can be LightFixModSwt = No_Action.

[0044] In one embodiment, to ensure effective reception of the instruction, the maintenance mode activation instruction sent by the HUT can be sent to the LCD in the form of event frames. For example, N consecutive frames of the same LightFixModSwt = 0x2:Open can be sent to the LCD, where N is an integer greater than or equal to 2, such as 3, 4, 5, 6, etc. When the LCD receives N identical event frames containing the maintenance mode activation instruction, i.e., after receiving N frames of LightFixModSwt = 0x2:Open, it obtains the vehicle status. When it determines that the vehicle status meets the conditions, it enters the maintenance mode, as described in step 102.

[0045] After the user activates the maintenance mode, both the HUT and LCD simultaneously memorize the current maintenance mode switch signal status. When a subsequent command corresponding to the headlight welcome operation is triggered, the welcome operation is performed directly without needing to determine whether the maintenance mode is activated, thus saving maintenance command execution time. It should be noted that both the HUT and LCD memorize the set welcome switch status. If the value memorized by the LCD differs from that of the HUT, the LCD will use the real-time value sent by the HUT.

[0046] Here, after sending N frames of valid instructions, the purpose of setting the value of the maintenance mode switch signal status bit to the preset value of the inactive flag is to prevent other operations from accidentally triggering error signals.

[0047] Step 102: When the vehicle status meets the preset conditions for activating the maintenance mode, enter the maintenance mode.

[0048] This step may also include: checking whether the vehicle status meets the preset conditions for activating the maintenance mode.

[0049] Here, vehicle status includes the vehicle's current gear and speed; maintenance mode can only be entered when the vehicle status meets the preset conditions for activating maintenance mode. The preset conditions for activating maintenance mode are that the vehicle's current gear is ON and the vehicle speed is 0 km / h.

[0050] The vehicle status meets the preset conditions for activating maintenance mode, including: the vehicle is currently in the ON gear and the vehicle speed is the preset speed, which is 0 km / h, meaning the vehicle is stationary.

[0051] This also includes situations where the vehicle's status does not meet the preset conditions for activating the maintenance mode, namely: the vehicle's current gear is not in the ON position, and / or the vehicle speed is greater than the preset speed. In other words, if either the vehicle's current gear being in the ON position or the vehicle speed being the preset speed is not met, the vehicle's status does not meet the preset conditions for activating the maintenance mode, and further checks are needed to determine if the vehicle's status meets these conditions.

[0052] Step 103: Upon receiving the command to deploy the vehicle lights, control the vehicle lights to perform the deployment action according to the command.

[0053] The headlights are positioned around the exterior headlights, and their deployment includes illuminating and extending beyond the vehicle's surface. See also Figure 2 The diagram shows the vehicle headlights. In this embodiment, the headlights corresponding to the maintenance mode are positioned around the exterior headlights, such as above, below, to the left, or to the right of the headlights. (See attached diagram.) Figure 2 The headlights are located above the headlights and are in a closed state. The headlights are represented by B, and the headlights are represented by A.

[0054] The headlight deployment command is sent from the Central Electronic Control Module (CEM) to the LDC via the LCM. The command is sent continuously as N event frames, with LCMCmd = 0x0: Noaction. When the LCD receives N consecutive frames of LCMCmd = 0x1: Open, the headlights deploy. The deployment action includes illuminating the headlights and extending them beyond the vehicle's surface. See [link to relevant documentation]. Figure 3 The diagram shown illustrates the headlights in their deployed state. Figure 3 It includes a headlight closed position 31, a headlight extended position 32, and a drive motor, which is used to drive the headlight to extend or close. By extending or closing the headlight, the technological feel and convenience of the headlight can be achieved, better reflecting the intelligence and humanization of the headlight.

[0055] In one embodiment, when a fault command is received during the unfolding or closing of the headlights, the headlights are controlled to stop operating and maintain their current state to prevent further damage from continued operation.

[0056] The fault command is generated by the LCM after detecting a headlight malfunction. Based on the cause of the malfunction, the LCM generates a fault command and sends it to the LDC, which then controls the headlight to stop operating. The fault command can be LCM_ExcpnRmnd = 0x0: No Exception. The cause of the malfunction could be a stuck rotor or a failed ice-breaking operation. This can be determined by checking for large fluctuations in the headlight current or whether a timeout has occurred.

[0057] In addition, faults detected by the LCM may include: excessively high headlight motor temperature, open circuit or short circuit in the headlight circuit, etc. In this case, the LCM will send an abnormal alarm signal to the HUT via the CEM, and the HUT will display the alarm information, including the cause of the fault. After the user understands the fault through the HUT and repairs it, they can reactivate the corresponding headlight function by resetting the virtual button corresponding to the headlight thermal protection state and the virtual button corresponding to the headlight fault state. See also Figure 4 The functional interface diagram includes, in addition to the headlight thermal protection state and headlight malfunction state, headlight anti-pinch state and headlight learning state. The headlight anti-pinch state activates when the mechanical moving parts of the headlight are jammed by an obstacle. The headlight learning state is activated because the headlight has two settings; when the movements of the two headlights are inconsistent, a malfunction is considered, requiring manual reset and restart.

[0058] See Figure 5 This diagram illustrates the interactions between different entities. Between the LCM and CEM, the LCM receives a command from the CEM to extend or deactivate the headlights and then controls the LDC to execute the corresponding headlight extension or deactivation action. The LCM sends detected faults or headlight status information to the CEM. Between the CEM and HUT, the CEM, acting as the central electronic control module, generates corresponding commands from the signals received from the HUT and forwards them to the LCM, such as a maintenance mode activation or deactivation signal. Figure 4 The value of the switch signal status bit corresponding to the function interface is used to generate the corresponding maintenance mode opening command, such as LightFixModSwt = 0x2: Open, or the maintenance mode closing command LightFixModSwt = 0x1: Close. HUT displays the vehicle headlight abnormality alarm, headlight status, headlight mode switch status, etc., sent by CEM in real time, so that users can understand the headlight status in a timely manner. Figure 5 It also includes ESP, which sends vehicle speed information to CEM so that CEM can detect whether the current vehicle status meets the preset conditions for activating maintenance mode.

[0059] pass Figure 4 and Figure 5 It can realize information interaction between different entities, and generate corresponding functional instructions by assigning values ​​to the status bits of the interactive information switch signal, and different entities execute the corresponding instructions to realize the corresponding operations.

[0060] In one embodiment, while the headlights are unfolding, the HUT displays footage of the unfolding action; conversely, while the headlights are returning to the closed state, the HUT displays footage of the headlights returning to the closed state, allowing the user to be aware of the headlight status. Additionally, while the headlights are unfolding, the headlight control button indicator light on the HUT illuminates to indicate the current unfolded state; conversely, while the headlights are returning to the closed state, the indicator light turns off to indicate the current closed state.

[0061] In one embodiment, the HUT has headlight control modes other than the maintenance mode. The maintenance mode is the automatic operation mode for the headlights, and therefore may also include manual mode and performance mode. The maintenance mode and other headlight control modes are set to be mutually exclusive. When the user clicks the virtual button corresponding to the maintenance mode, the virtual buttons corresponding to other modes are disabled. To prevent repeated operations, after the user clicks the virtual button corresponding to the maintenance mode, the virtual button corresponding to the maintenance mode is disabled, but the signal status bits of the performance mode and welcome mode switches remain unchanged.

[0062] In this embodiment of the invention, upon receiving a maintenance mode activation command and confirming that the vehicle's status meets preset conditions for maintenance mode activation, the system enters maintenance mode. Upon receiving a headlight deployment command, the system controls the headlights to deploy automatically, enhancing their effect and increasing their range of motion. Furthermore, the headlights are positioned around the exterior headlights, and their deployment includes illuminating and extending beyond the vehicle's surface, allowing users to fully experience the technological sophistication and convenience of intelligent flip-up lights.

[0063] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0064] The following are device embodiments of the present invention. For details not described in detail, please refer to the corresponding method embodiments described above.

[0065] Figure 6 A schematic diagram of the control device for vehicle headlight maintenance mode provided in an embodiment of the present invention is shown. For ease of explanation, only the parts related to the embodiment of the present invention are shown, and are described in detail below:

[0066] like Figure 6 As shown, the control device for the vehicle headlight maintenance mode includes: an acquisition module 601 and a control module 602.

[0067] The acquisition module 601 is used to acquire the vehicle status when a maintenance mode activation command is received;

[0068] The control module 602 is used to enter the maintenance mode when the vehicle status meets the preset conditions for opening the maintenance mode;

[0069] The control module 602 is also used to control the headlights to perform an unfolding action when it receives a headlight unfolding command. The headlights are located around the front headlights outside the vehicle. The unfolding action of the headlights includes illuminating the headlights and extending them out of the vehicle body surface.

[0070] In one possible implementation, when the acquisition module 601 receives the maintenance mode activation command, it is used to:

[0071] The connection receives N identical event frames, each event frame including a maintenance mode activation command, where N is a positive integer greater than or equal to 2.

[0072] In one possible implementation, the maintenance mode activation command is generated by the HUT based on the received trigger signal, and the maintenance mode activation command is issued in the form of an event frame, and the value of the corresponding maintenance mode switch signal status bit is set to a preset value that indicates no action.

[0073] In one possible implementation, the vehicle state includes the vehicle's current gear and speed;

[0074] The control module 602 is used to enter maintenance mode when the vehicle is currently in the ON gear and the vehicle speed is the preset speed.

[0075] In one possible implementation, the control module 602 is further configured to: detect whether the vehicle status meets the preset conditions for activating the maintenance mode;

[0076] And when the vehicle is not currently in the ON gear, and / or the vehicle speed is greater than the preset speed, the process will jump to the step of "checking whether the vehicle status meets the preset conditions for opening the maintenance mode".

[0077] In one possible implementation, the control module 602 is further used for:

[0078] If a fault command is received during the unfolding or closing of the headlights, the headlights will stop operating and remain in their current state.

[0079] In one possible implementation, while the headlights are unfolding, the HUT plays footage of the headlights unfolding, and the headlight control button indicator lights up.

[0080] As the headlights return to the closed position, the HUT displays a video of the headlights returning to the closed position, and the headlight control button indicator light turns off.

[0081] The aforementioned headlight maintenance mode control device acquires the vehicle status upon receiving a maintenance mode activation command via an acquisition module. When the vehicle status meets the preset conditions for activating the maintenance mode, the control module enters maintenance mode. Upon receiving a headlight deployment command, it controls the headlights to automatically deploy, enhancing the headlight effect and increasing the headlight movement range. Furthermore, since the headlights are positioned around the exterior headlights, the deployment action includes illuminating the headlights and extending them beyond the vehicle's surface, allowing users to fully experience the technological sophistication and convenience of intelligent flip-up lights.

The control module is used to detect whether the vehicle status meets the preset conditions for opening the maintenance mode; when the vehicle status does not meet the preset conditions for opening the maintenance mode, it continues to detect whether the vehicle status meets the preset conditions for opening the maintenance mode; when the vehicle status meets the preset conditions for opening the maintenance mode, it enters the maintenance mode; the vehicle status includes the vehicle's current gear and speed; the HUT and LCD simultaneously memorize the value of the current maintenance mode switch signal status bit, so that when the headlight deployment command is triggered later, the headlight deployment action is performed directly without the need to perform a judgment operation on whether the maintenance mode is open; The headlight deployment command is sent from the CEM to the LCD via the LCM. The control module is also used to control the headlights to perform deployment actions according to the headlight deployment command when the LCD receives the headlight deployment command. The headlights are located around the front headlights outside the vehicle. The headlight deployment action includes illuminating the headlights and extending them out of the vehicle body surface.
