Description

Technical Field

[0001] This application relates to the field of vehicle lighting control technology, and in particular to a method and device for controlling a vehicle-mounted portable auxiliary light. Background Technology

[0002] To improve the convenience and safety of retrieving items from in-vehicle storage spaces, supplementary lights are widely used in various scenarios such as retrieving items from in-vehicle storage spaces, outdoor camping, and emergency lighting.

[0003] Currently, auxiliary lights are mainly controlled in three ways. The first type is manually controlled auxiliary lights, whose on / off operation relies entirely on the user's physical operation. Therefore, the user must accurately locate and operate the light before retrieving items. If the vehicle's infotainment system is not activated or the user's hands are unavailable, immediate illumination is not possible. The second type is sensor-activated lights based on human infrared or light sensors. These lights directly turn on or off based on sensor detection results. Due to their simple control logic, they are prone to contradictions, such as not lighting when illumination is needed and remaining on when there is no need for illumination. The third type is in-vehicle lights controlled via the vehicle's infotainment system or mobile applications. Normal operation requires the vehicle's infotainment system to be activated, Bluetooth to be connected, and the application to be ready. However, at the moment the vehicle is unlocked and the storage space is opened, the vehicle's infotainment system often has not yet started up or recognized the retrieval scenario, thus failing to provide illumination immediately upon opening the storage space, resulting in a delayed lighting response.

[0004] However, in practical use, the lighting needs of in-vehicle storage spaces are not always driven by a single control source. Because the different control methods in existing solutions are independent of each other, it is difficult to achieve timely response and coordinated control of supplementary lighting.

[0017] Figure 1 A flowchart illustrating a method for controlling a vehicle-mounted portable auxiliary light, provided in an embodiment of this application; Figure 2 This is a schematic diagram of a vehicle-mounted portable auxiliary light control device provided in an embodiment of this application. Detailed Implementation

[0018] To better understand the above technical solutions, exemplary embodiments of this application will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of this application are shown in the drawings, it should be understood that this application can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this application can be understood more clearly and thoroughly, and that the scope of this application can be fully conveyed to those skilled in the art.

[0019] Figure 1 This is a flowchart illustrating a method for controlling a vehicle-mounted portable auxiliary light, as provided in an embodiment of this application. Figure 1 As shown, the method includes: In standby mode, the S100 and fill light acquire data from multiple sensor sources in real time, determine the light intensity, and generate motion recognition results to generate control output signals.

[0020] For example, the supplementary light is in a low-power standby state, the LED light source is off, and the control unit, light sensor, and infrared sensor maintain low-power detection to collect the current ambient light intensity. The infrared sensor also detects in real time whether there are human actions such as approaching, searching, or moving. When the collected light intensity is lower than a preset brightness threshold, it is determined that the ambient brightness is too dark. If human action is detected at this time, it means that the current scene needs to provide supplementary lighting. The supplementary light then responds quickly and generates a control output signal based on the light intensity to meet the lighting requirements.

[0021] Multi-source sensors can also be selected from one or more of the following: human infrared sensor, millimeter-wave radar, ultrasonic, proximity sensor, distance sensor, camera / image sensor, and fusion for action recognition and judgment. The light sensor can determine the light intensity by means of camera brightness estimation, etc. If the supplementary lighting control unit has a communication connection with the vehicle's system, it can also obtain ambient light information or vehicle sensor information through the vehicle's system.

[0022] S200. Based on the preset priority activation rules, determine the currently effective control signals; the control signals include: control output signals, vehicle control signals and forced control signals; the preset priority activation rules include: sorting the currently received control signals according to the order of forced control signals, vehicle control signals and control output signals in terms of activation priority.

[0023] The mandatory control signal originates from the internal forced judgment of the auxiliary light control unit or is generated by direct user control. The vehicle-mounted control signal originates from the control signal generated by the vehicle-mounted system in specific scenarios after the auxiliary light control unit establishes a connection with the vehicle-mounted system, and is then sent to the auxiliary light control unit. The control output signal is generated by the auxiliary light control unit based on multi-source sensor data. The priority of activation, from highest to lowest, is as follows: mandatory control signal, vehicle-mounted control signal, and control output signal. When multiple control signals are generated or received by the auxiliary light control unit at the same time, the control signal with the highest activation priority is selected as the currently active control signal, and other control signals are suspended or discarded.

[0024] S300: If a forced control signal is received, the lighting state of the fill light body is controlled based on the forced control signal; otherwise, the automatic lighting mode is entered. The automatic lighting mode includes: when the light intensity is lower than the preset brightness and the action recognition result is different from the preset standby state, the fill light body is controlled to turn on the lighting based on the control output signal; after the lighting is turned on and a preset delay time has elapsed, the lighting is turned off and the standby mode is restored.

[0025] For example, when the fill light control unit receives a forced control signal, it directly uses the forced control signal as the currently effective control signal to control the fill light to perform the corresponding on or off lighting operation. During the period when the forced control signal is effective, other types of control signals do not participate in the control decision.

[0026] Since the vehicle's infotainment system is not always active, it may not respond promptly to the lighting needs of the current scene. Therefore, when the auxiliary light control unit does not receive a mandatory control signal, the auxiliary light prioritizes entering the automatic lighting mode driven by the control output signal. This does not conflict with the vehicle's infotainment system's control signal having higher priority than the control output signal. In automatic lighting mode, the auxiliary light control unit continuously acquires light intensity information and motion recognition results, comparing them with preset brightness thresholds and preset standby states, respectively. When the light intensity is lower than the preset brightness threshold, and the motion recognition result differs from the preset standby state (e.g., the motion recognition result indicates the detection of a person approaching, searching, or moving), the auxiliary light control unit determines that there is a lighting need in the current environment and controls the auxiliary light to turn on based on the control output signal. After the auxiliary light turns on, the auxiliary light control unit continuously monitors whether the motion recognition result returns to the preset standby state. The preset standby state is when the motion recognition result is stationary, or the effective detection range of the infrared sensor is normal and not covered. If the action recognition result remains in the preset standby state for the preset delay time, it indicates that no lighting is needed in the current scene. In this case, the auxiliary light control unit controls the auxiliary light to turn off the illumination and returns to standby mode, waiting for the next trigger. The preset delay time can be calibrated according to the vehicle model, installation location, or specific application scenario, for example, set to 5 seconds, 10 seconds, or other suitable durations.

[0027] S400, in response to the vehicle control unit takeover command, sends the current lighting parameters of the auxiliary light and enters the vehicle control unit takeover mode. Based on the vehicle control unit control signal, it controls the lighting state of the auxiliary light body; the vehicle control signal includes the lighting parameters to ensure continuous lighting.

[0028] While the auxiliary light is providing illumination in automatic lighting mode, if the vehicle's infotainment system has been activated and recognizes a preset scenario such as retrieving an item, opening a lid, or providing illumination in a storage space, the system sends a takeover command to the auxiliary light. Upon receiving the takeover command, the auxiliary light acquires its current lighting parameters and sends them to the infotainment system. The infotainment system, upon receiving these parameters, generates a control signal based on them and sends it back to the auxiliary light. Because the control signal contains the auxiliary light's current lighting parameters, the output value of the control signal remains unchanged when the auxiliary light control unit switches from automatic lighting mode to takeover mode; the lighting status does not flicker, interrupt, or abruptly change due to the mode switch. The auxiliary light control unit switches the currently effective control signal from a control output signal to an infotainment control signal, entering takeover mode. Thereafter, the infotainment control signal dominates the update of the auxiliary light's lighting status, and the auxiliary light control unit no longer generates control output signals based on local sensor data.

[0029] S500: When the vehicle takeover command is terminated and no forced control signal is received, the auxiliary lights enter automatic lighting mode.

[0030] While the auxiliary light is in vehicle-to-everything (V2X) takeover mode, the auxiliary light control unit continuously monitors the validity of the V2X takeover command. The V2X takeover command terminates when the communication link between the auxiliary light and the V2X is lost, or when the V2X actively relinquishes control. After detecting the termination of the V2X takeover command, the auxiliary light control unit further determines whether a mandatory control signal has been received. If a mandatory control signal exists, the lighting control operation corresponding to the mandatory control signal is executed first; if no mandatory control signal is received, the auxiliary light exits the V2X takeover mode and re-enters automatic lighting mode. In automatic lighting mode, the auxiliary light control unit re-determines the issue based on light intensity information and motion recognition results. Therefore, when V2X control becomes unavailable or actively exits, the auxiliary light can automatically switch back to its own closed-loop control, thereby improving the continuity and reliability of the lighting function.

[0031] Optionally, in some embodiments of this application, the supplementary light, in standby mode, acquires light intensity and motion recognition results in real time to generate a control output signal, including: the lighting state is off, light intensity is acquired through a light sensor, and motion recognition results are identified through an infrared sensor; the motion recognition results include human motion recognition results and / or effective recognition distance information; and the light intensity and motion recognition results are used as input parameters for generating the control output signal.

[0032] For infrared sensor signals, the fill light control unit extracts multiple action characteristics within a preset time window, including: the duration for which the output signal is continuously higher than a preset action threshold, the number of actions exceeding the preset action threshold within the preset time window, and the signal's trend within the preset time window. Simultaneously, the fill light control unit can also combine this information with a distance sensor to obtain the minimum distance value detected within the preset time window.

[0033] The supplementary lighting control unit normalizes the aforementioned duration, number of actions, and trend characteristics, then performs a weighted sum to generate an action confidence score. Simultaneously, it compares the minimum distance value detected by the distance sensor with a preset distance threshold to generate a distance determination result. When the action confidence score is greater than the preset action confidence threshold and / or the minimum distance value is less than the preset distance threshold, the supplementary lighting control unit determines that the current action recognition result differs from the preset standby state. This indicates that there is a valid action in the current environment, such as a person approaching, searching, or moving. Ultimately, based on the action recognition result, the control unit generates a control output signal that meets the current lighting requirements according to the light intensity value, controlling the supplementary lighting to turn on.

[0034] In this embodiment of the application, the fill light control unit can determine effective actions based on multi-dimensional feature fusion in standby mode through the above method, reducing frequent false lighting caused by instantaneous interference or false triggering from a distance, while maintaining response sensitivity in real object retrieval scenarios.

[0035] Optionally, in some embodiments of this application, the forced control signal includes: a safety protection signal generated by the auxiliary light based on the power monitoring circuit or the temperature monitoring circuit, or a received user control signal; wherein, the safety protection signal has a higher priority than the user control signal; the vehicle control signal is generated by the vehicle system after recognizing the current auxiliary light usage scenario; the control output signal is generated by the auxiliary light based on the light intensity and action recognition results; the currently effective control signal is determined based on a preset priority rule, including: when there is only one type of control signal, it is directly determined as the currently effective control signal; when two or more control signals are received at the same time, the control signal with the higher priority is determined as the currently effective control signal.

[0036] The fill light incorporates a power monitoring circuit and a temperature monitoring circuit. The power monitoring circuit monitors the battery's current charge level in real time, generating a low-battery protection signal when the charge level falls below a preset threshold. The temperature monitoring circuit monitors the internal temperature of the lamp body or the driver circuit in real time, generating an overheat protection signal when the temperature exceeds a preset threshold. The fill light control unit also receives user control signals directly from the user via physical buttons, touch sensors, or voice commands, such as turning the light on or off by pressing a power button. Upon receiving either a safety protection signal or a user control signal, the fill light control unit recognizes them as mandatory control signals. The safety protection signals generated based on the low-battery and overheat protection signals have higher priority than user control signals. This means the fill light control unit prioritizes executing the lighting control operations corresponding to the safety protection signals, such as reducing brightness or shutting down the output when the battery is low or the light is overheating, to improve the safety of the fill light during use.

[0037] Upon receiving a manual shutdown command from the user, the supplementary lighting control unit initiates a preset suppression timer. During this time, even if the user approaches the storage space again and the ambient light intensity remains below a preset brightness threshold, the supplementary lighting control unit will prevent the automatic lighting mode from being triggered. This reduces the likelihood of the light immediately relighting due to accidental sensor activation after the user manually shuts it off. After the suppression time ends, the supplementary lighting control unit resumes its normal automatic lighting mode activation function.

[0038] The vehicle's infotainment system establishes a wireless communication connection with the auxiliary lighting control unit via a Bluetooth communication module. After identifying the current auxiliary lighting usage scenario, the system generates a control signal and sends it to the auxiliary lighting control unit wirelessly. The system identifies the current auxiliary lighting usage scenario based on at least one of the following: front trunk open / closed status, rear trunk open / closed status, vehicle locked status, driving status, parked status, infotainment system wake-up status, and / or Bluetooth connection status. For example, when the system detects that the trunk is open and the vehicle is parked, it identifies it as a retrieval scenario; when the system detects that the vehicle is parked and the user enters camping mode via the infotainment panel, it identifies it as a lighting scenario.

[0039] In automatic lighting mode, the supplementary lighting control unit generates a control output signal based on the light intensity collected by the light sensor and the motion recognition result detected by the infrared sensor. When the light intensity is lower than a preset brightness threshold and the motion recognition result is different from the preset standby state, the supplementary lighting control unit generates a control output signal to turn on the lighting.

[0040] The auxiliary light control unit may receive multiple control signals simultaneously. For example, while executing a control output signal in automatic lighting mode, it may also receive a mandatory control signal input by the user via physical buttons, or simultaneously receive a vehicle control signal from the vehicle's infotainment system. In response to these situations, the auxiliary light control unit determines the currently active control signal according to a preset priority rule: when only one control signal exists at a time, that signal is directly designated as the active signal; when two or more control signals exist simultaneously, their priorities are compared, and the control signal with the highest priority is designated as the active signal, while the remaining control signals are suspended or discarded. The priority, from highest to lowest, is: mandatory control signals belonging to safety protection signals, mandatory control signals belonging to user control signals, vehicle control signals, and control output signals. Therefore, the auxiliary light can make a unique control decision based on a clear priority rule at any given time, thereby reducing the risk of conflicts between multiple control signals.

[0041] Optionally, in some embodiments of this application, the supplementary light uses a safety protection signal generated by a power monitoring circuit or a temperature monitoring circuit, including: acquiring evaluation parameters and the current usage scenario of the supplementary light; the evaluation parameters include the current battery power, the current lamp body temperature, the current output power and / or continuous working duration; and based on the current usage scenario of the supplementary light, determining the risk threshold and protection response mode corresponding to each evaluation parameter, and generating a safety protection signal for the corresponding scenario.

[0042] For example, the auxiliary light control unit obtains the current battery level through a power monitoring circuit, the current lamp body temperature through a temperature monitoring circuit, the current output power through a power management circuit, and the continuous operating time through an internal timer. The auxiliary light control unit selects at least two of the above evaluation parameters as input parameters for safety protection evaluation, and obtains the current auxiliary light usage scenario from the vehicle's infotainment system, or determines it automatically based on local conditions.

[0043] The current usage scenarios for the supplementary lighting include item retrieval, illumination, and standby scenarios. Through vehicle-mounted system identification, the system dynamically adjusts various risk thresholds and outputs safety protection signals adapted to the usage scenario. Specifically, the vehicle-mounted system identifies the current supplementary lighting usage scenario based on at least one of the following: front trunk open / closed status, rear trunk open / closed status, vehicle locked status, driving status, parked status, vehicle-mounted system wake-up status, and / or Bluetooth connection status. For example, when the vehicle-mounted system detects that the trunk is open and the vehicle is parked, it identifies it as an item retrieval scenario and sends an item retrieval scenario identifier to the supplementary lighting control unit; when the vehicle-mounted system detects that the vehicle is parked and the user enters camping mode via the vehicle-mounted system panel, it identifies it as an illumination scenario and sends a illumination scenario identifier to the supplementary lighting control unit; when the vehicle-mounted system detects that the vehicle is locked or driving, it identifies it as a standby scenario and sends a standby scenario identifier to the supplementary lighting control unit.

[0044] For example, in the object retrieval scenario, the object retrieval operation only needs to be completed in a short time. The power protection threshold is reduced from 15% to 8% to extend the lighting time of the current object retrieval scenario. When the battery power percentage is not lower than 8%, no safety protection signal is output. Otherwise, the lighting function is restricted. By setting the drive duty cycle of the safety protection signal to 0%, automatic lighting is prohibited, thereby stopping the lighting and reducing the risk of over-discharge of the fill light battery. At the same time, the temperature protection threshold is increased from 65°C to 70°C, so that the fill light does not immediately turn off in a short time. This achieves temperature protection while improving the continuity of fill light use.

[0045] In lighting scenarios, such as outdoor camping, supplementary lights are often used for extended periods, which increases the risk of overheating. To improve the safety of the lights, the temperature protection threshold is lowered from 65°C to 60°C. When the temperature of the lights exceeds 60°C, the duty cycle of the safety protection signal output is reduced to decrease the lighting brightness or send a reminder signal to the user.

[0046] In standby mode, when the fill light is not in use, if the battery level is lower than the power protection threshold or the lamp body temperature exceeds the temperature protection threshold, the fill light control unit will directly output a safety protection signal to shut down the lamp and prevent switching to automatic lighting mode until the battery level and lamp body temperature return to normal.

[0047] In other embodiments of this application, the safety protection also includes triggering operations such as reminders, reducing brightness, limiting color temperature / brightness, prohibiting automatic lighting, or turning off output in cases such as low battery power, high ambient temperature, abnormal charging, overheating of the lamp body, or communication abnormality, according to preset protection strategies.

[0048] This application embodiment effectively reduces the problem of overprotection or underprotection in different scenarios by determining the risk threshold and protection response method of each evaluation parameter according to the usage scenario, thereby adapting to the actual needs of different usage scenarios.

[0049] Optionally, in some embodiments of this application, generating action recognition results includes: filtering the collected sensor data using an extended Kalman filter algorithm constrained by human kinematic parameters to generate action recognition results; wherein the noise covariance matrix parameter of the extended Kalman filter algorithm is determined according to the current lighting usage scenario.

[0050] For example, the supplemental lighting control unit acquires raw sensor data through infrared sensors and / or distance sensors. Since human movement near the vehicle's storage space is physically restricted, the supplemental lighting control unit uses pre-stored human kinematic parameters as physical prior constraints to construct a state transition model using an extended Kalman filter algorithm.

[0051] Specifically, the supplementary lighting control unit constructs a state vector x=[d,v,a] that includes the target distance, approach speed, and acceleration. T Where d represents the target distance detected by the sensor, v represents the target velocity, a represents the target acceleration, and T represents the transpose. A state transition matrix is ​​established based on a uniformly accelerated motion model to predict the state vector at the current moment. This state transition matrix includes parameters such as the sampling time interval, used to predict the current state based on the state at the previous moment. Since the infrared signal intensity collected by the infrared sensor has a nonlinear relationship with the target distance (i.e., the signal intensity is inversely proportional to the square of the distance), and the distance sensor has nonlinear characteristics such as blind spots or multipath reflections at close range, the supplementary lighting control unit uses an extended Kalman filter algorithm to process this nonlinear observation relationship and corrects the predicted state in the update step.

[0052] In the prediction step, human kinematic parameters are used as constraints for state transitions, with pre-set velocity and acceleration limits. When the predicted approach velocity exceeds the velocity limit or the predicted acceleration exceeds the acceleration limit, the supplementary lighting control unit determines that the current predicted state is unreasonable. It clamps the corresponding components in the predicted state to the physical limit range and simultaneously increases the process noise covariance matrix, reducing the confidence in the predicted state and making the filtering results more dependent on the current observation values ​​in subsequent update steps. By combining clamping and covariance adjustment, abnormal jumps in state estimation caused by instantaneous sensor interference are effectively reduced, improving the stability of action recognition results.

[0053] The supplementary lighting control unit receives scene identifiers from the vehicle's infotainment system via wireless communication and determines the filtering parameters of the extended Kalman filter algorithm based on the current supplementary lighting usage scenario. Specifically, after the vehicle's infotainment system identifies the current supplementary lighting usage scenario, it sends the corresponding scene identifier to the supplementary lighting control unit. The supplementary lighting control unit determines the current scene type based on the received scene identifier and then adjusts the process noise covariance matrix and / or measurement noise covariance matrix of the extended Kalman filter algorithm. In object retrieval scenarios, the process noise covariance matrix is ​​increased to make the filter more sensitive to state changes, reduce the filter's over-reliance on motion models, and allow action recognition results to quickly respond to changes in human movement. In lighting scenarios, the acceleration term covariance in the process noise covariance matrix is ​​reduced to suppress fluctuations in action recognition results caused by slight human body tremors. In standby scenarios, the measurement noise covariance matrix is ​​increased to make the filter smoother and suppress false triggering caused by sensor noise.

[0054] This embodiment generates motion recognition results by using the target distance and target velocity estimates output by the extended Kalman filter algorithm. This enables stable estimation of physically meaningful target distance and velocity from noisy, nonlinear sensor data, reducing false triggering caused by transient sensor interference. Furthermore, when the communication connection is not established or the vehicle-mounted system is not in takeover mode, the supplementary lighting control unit can maintain default filtering parameters for motion recognition. It then switches to the corresponding filtering parameter configuration after the vehicle-mounted system issues a scene identifier, thus balancing vehicle-mounted system linkage and local autonomous control.

[0055] Optionally, in some embodiments of this application, in response to a vehicle-mounted unit takeover command, the current lighting parameters of the supplementary light are sent, and the vehicle-mounted unit takeover mode is entered. Based on the vehicle-mounted unit control signal, the lighting state of the supplementary light body is controlled, including: after establishing wireless communication between the vehicle-mounted unit and the supplementary light, identifying the current usage scenario of the supplementary light, and sending a vehicle-mounted unit takeover command to the supplementary light; the supplementary light responds to the vehicle-mounted unit takeover command and sends the current lighting parameters to the vehicle-mounted unit; the lighting parameters include the current driving duty cycle value and / or color temperature value of the light body; the vehicle-mounted unit generates a vehicle-mounted unit control signal based on the current usage scenario and lighting parameters of the supplementary light and sends it back to the supplementary light; through a seamless handover method, the supplementary light switches from automatic control mode to vehicle-mounted unit takeover mode, stops generating control output signals, and controls the lighting state of the supplementary light body based on the vehicle-mounted unit control signal.

[0056] During automatic lighting mode, the auxiliary light control unit establishes a wireless communication connection with the vehicle's infotainment system. When the infotainment system recognizes a specific usage scenario, it sends a takeover command to the auxiliary light, which then enters takeover mode. Once the infotainment system detects that a communication connection has been established with the auxiliary light, it can obtain vehicle status information, including at least one of the following: front trunk open / closed status, rear trunk open / closed status, locked status, driving status, parked status, infotainment system wake-up status, and / or Bluetooth connection status. Based on this status information, the infotainment system identifies the current auxiliary light usage scenario. For example, if the infotainment system detects that the trunk is open and the vehicle is parked, it identifies it as a retrieval scenario.

[0057] The vehicle's infotainment system sends a takeover command to the auxiliary lights. Upon receiving the takeover command, the auxiliary lights control unit reads the real-time drive parameters of the lights, including the current drive duty cycle and / or color temperature, as lighting parameters, and sends these lighting parameters back to the vehicle's infotainment system.

[0058] After receiving the lighting parameters from the auxiliary light, the vehicle's infotainment system generates control signals based on these parameters and the currently identified usage scenario. For example, in a scenario where items are being retrieved, the system maintains the current brightness output based on the lighting parameters, and simultaneously generates subsequent brightness adjustment or shutdown commands as control signals based on the duration the trunk is open, user actions, or changes in vehicle status, and sends these commands back to the auxiliary light.

[0059] In this embodiment, the vehicle-mounted system identifies the current usage scenario of the auxiliary light and actively initiates a takeover. The system uses the current illumination parameters of the auxiliary light as the basis for generating the vehicle-mounted system control signal, thereby matching the vehicle-mounted system control signal with the current state of the auxiliary light. This improves the consistency between the vehicle-mounted system control signal and the actual state of the auxiliary light, as well as the matching efficiency and control accuracy during the transfer of auxiliary light control.

[0060] Optionally, in some embodiments of this application, seamless handover includes: the supplementary light uses the lighting parameters as the output value of the current control signal, so that the light output state remains unchanged before and after the control signal source is switched, and the control signal is switched from the control output signal to the vehicle control signal; after the control signal source is switched, the supplementary light updates the output value of the current control signal based on the vehicle control signal.

[0061] The auxiliary light control unit switches the currently effective control signal from the control output signal autonomously generated in automatic lighting mode to the vehicle's infotainment system control signal. It uses the current lighting parameters reported by the auxiliary light to the vehicle's infotainment system as the initial output value of the vehicle's control signal, ensuring that the drive output value remains consistent before and after the switch. The auxiliary light control unit stops generating control output signals based on local light intensity information and motion recognition results. Instead, it updates the drive duty cycle and / or color temperature value of the lamp body according to the vehicle's infotainment system control signal to control the lighting state of the auxiliary light. During the control transfer process, the auxiliary light control unit does not reset, restart, or reset the drive output to zero; it only switches the source of the control signal from local automatic judgment logic to the control signal issued by the vehicle's infotainment system.

[0062] After the control signal source is switched, if the target drive output value corresponding to the vehicle control signal is different from the current drive output value, the drive output value can be gradually adjusted from the current value to the target value according to the preset gradual change rate so that the brightness change of the auxiliary light is smooth and continuous.

[0063] In this embodiment, when the supplementary light switches from automatic lighting mode to vehicle control mode, the output value of the current control signal remains unchanged, and the lighting state does not flicker, interrupt, or change suddenly in brightness due to the switch of control mode, thereby achieving a seamless transfer of control between the supplementary light body and the vehicle system.

[0064] Optionally, in some embodiments of this application, when the first dimming curve of the supplementary light is different from the second dimming curve of the vehicle system, the supplementary light updates the output value of the current control signal based on the vehicle system control signal, which further includes: the vehicle system acquiring the lighting parameters uploaded by the supplementary light, the lighting parameters including the curve identifier of the first dimming curve; the vehicle system determining the target physical brightness value corresponding to the supplementary light under the current driving duty cycle value according to the curve identifier; the vehicle system mapping the target physical brightness value to the equivalent driving duty cycle value under the second dimming curve according to the second dimming curve; the vehicle system generating a vehicle system control signal based on the equivalent driving duty cycle value and sending it to the supplementary light; the supplementary light updating the output value of the current control signal with the equivalent driving duty cycle value according to the vehicle system control signal.

[0065] For example, the auxiliary light control unit pre-stores a first dimming curve for the auxiliary light itself. After establishing a communication connection with the vehicle's infotainment system, during the lighting parameter reporting process, the auxiliary light control unit sends the curve identifier of the first dimming curve to the vehicle's infotainment system. The curve identifier may include a curve type identifier and / or curve parameter values. The curve type identifier may be a linear dimming curve, a logarithmic dimming curve, an exponential dimming curve, or a gamma correction curve. The vehicle's infotainment system pre-stores its own second dimming curve. After receiving the current drive duty cycle value and the curve identifier of the first dimming curve reported by the auxiliary light, the vehicle's infotainment system determines the type of the first dimming curve and its mapping relationship with the second dimming curve based on the curve identifier, thereby calculating the target physical brightness value.

[0066] Specifically, the vehicle-mounted system can calculate the target physical brightness value using piecewise linear interpolation. Based on the curve identifier of the first dimming curve, the system obtains a sequence of piecewise linear calibration points corresponding to the first dimming curve. This sequence contains multiple correspondences between drive duty cycle values ​​and physical brightness values. For example, taking a Gamma 2.2 correction curve as the first dimming curve, the drive duty cycle value can be any value within the range of 0% to 100%. The system obtains the current drive duty cycle value P = 50% and the calibration point sequence of the first dimming curve. The system calibrates the interval [P] within the first dimming curve. k ,P k+1 The corresponding calibrated physical brightness range is [L]. k ,L k+1 The vehicle's infotainment system uses piecewise linear interpolation to calculate the target physical brightness value L corresponding to the current drive duty cycle value P. target : ; Among them, L k+1 and L k These represent the upper and lower boundaries of the physical brightness value, P. k+1 and P k These represent the upper and lower boundaries of the drive duty cycle value, respectively. Both the physical brightness value and the drive duty cycle value are normalized dimensionless values. The target physical brightness value L target The accuracy depends on the number and distribution of calibration points on the first dimming curve; more calibration points and a more uniform distribution can improve the interpolation accuracy.

[0067] Alternatively, the vehicle-mounted system can also use nonlinear interpolation methods, such as cubic spline interpolation or Hermite interpolation, to achieve higher precision mapping.

[0068] Calculate the target physical brightness value L corresponding to the supplementary light under the current driving duty cycle. target Then, the vehicle's infotainment system adjusts the target physical brightness value L according to its own second dimming curve. target This is mapped to an equivalent drive duty cycle value P′. The vehicle system acquires a piecewise linear calibration point sequence of the second dimming curve and calibrates the target physical brightness value L within the second dimming curve. target The interval is [L] m ,L m+1 The corresponding drive duty cycle range is [P]. m ,P m+1 The vehicle-mounted system uses piecewise linear interpolation to calculate the target physical brightness value L. target The corresponding equivalent drive duty cycle P': ; In practical applications of supplemental lighting, the human eye is more sensitive to changes in brightness in dark areas and relatively less sensitive to changes in brightness in bright areas. Therefore, in some embodiments of this application, the second dimming curve can set more dense calibration points in the dark area to improve the mapping accuracy of the low-brightness range, thereby optimizing the perceived effect on the human eye.

[0069] The vehicle's infotainment system uses the equivalent drive duty cycle P′ as a basis, combines it with the currently identified usage scenario to generate a vehicle control signal, and sends this control signal to the auxiliary light. The auxiliary light control unit updates the output value of the current control signal based on the received vehicle control signal and the equivalent drive duty cycle P′. Because this mapping process uses the target physical brightness value L... target A mapping conversion was performed between the first dimming curve of the auxiliary light and the second dimming curve of the vehicle system for the intermediate quantity. Even if the dimming curve types of the auxiliary light and the vehicle system are different, the equivalent drive duty cycle value issued by the vehicle system can make the auxiliary light produce the same physical brightness as before the replacement, thereby ensuring the consistency of physical brightness before and after the replacement.

[0070] This application embodiment identifies the difference between the dimming curves of the auxiliary light and the vehicle's infotainment system by using curve markers, and uses a piecewise linear interpolation algorithm to map the physical brightness corresponding to the current driving duty cycle value of the auxiliary light to the equivalent driving duty cycle value under the vehicle's infotainment system's dimming curve. This solves the problem of brightness jump at the moment of replacement caused by different dimming curves, and enables the auxiliary light to maintain the same physical brightness before and after replacement even when the dimming curves are inconsistent, further improving the reliability and applicability of seamless replacement.

[0071] It should be noted that piecewise linear interpolation in the above embodiments is used to achieve efficient calculation under the condition of limited computing power in the supplementary lighting control unit, such as the MCU (Microcontroller Unit). Piecewise linear interpolation only requires storing a small number of calibration points and the calculation process is simple, making it suitable for real-time execution on low-computing-power MCUs. When the vehicle's computing power allows, higher-precision interpolation algorithms such as cubic spline interpolation or Hermite interpolation can also be used to further improve the mapping accuracy.

[0072] Optionally, in some other embodiments of this application, the vehicle system calculates the equivalent drive duty cycle value based on the second dimming curve using the Newton-Raphson iterative method.

[0073] Specifically, the vehicle system uses the current drive duty cycle of the auxiliary light as the initial iteration value; based on the second dimming curve, the Newton-Raphson iteration method is used to iteratively solve the initial iteration value until the error between the physical brightness value of the second dimming curve under the current iteration value and the target physical brightness value is less than the preset error threshold; the current iteration value after iteration convergence is determined as the equivalent drive duty cycle value.

[0074] For example, when the first dimming curve of the auxiliary light differs from the second dimming curve of the vehicle's infotainment system, the system needs to map the target physical brightness value corresponding to the current drive duty cycle of the auxiliary light to the equivalent drive duty cycle value under the second dimming curve. When the second dimming curve is a nonlinear curve (e.g., an exponential dimming curve, a logarithmic dimming curve, or an S-shaped dimming curve) or cannot be accurately fitted by a low-order polynomial, the system uses the Newton-Raphson iterative method for numerical solution.

[0075] Specifically, the vehicle-mounted system uses the current drive duty cycle value P of the supplementary light as the initial iteration value P0. Based on the second dimming curve, the system establishes a mapping function f(P) between the drive duty cycle value and the physical brightness value, where f(P) represents the physical brightness value corresponding to the second dimming curve when the drive duty cycle value is P, and solves the equation f(P) = L. target This results in a new drive duty cycle value P', ensuring that under the second dimming curve, when the fill light is driven by P', it can output the same physical brightness L as the fill light in its current state. target Since f(P) may be a nonlinear function, the Newton-Raphson iteration method is used to numerically solve the equation, starting from the initial value P0 and iterating step by step to approximate the solution P' of the equation.

[0076] During the iteration process, the vehicle's infotainment system will display the drive duty cycle value P after each iteration. i+1 Substituting into the mapping function f(P), where i represents the iteration number, calculate the error |f(P)| between the current physical brightness value and the target physical brightness value. i+1 ) L target When the error is less than a preset error threshold, the iteration is considered to have converged, the iteration is stopped, and the current driving duty cycle value P is set. i+1 The equivalent driving duty cycle value P′ is determined.

[0077] The embodiments of this application calculate the equivalent drive duty cycle value using the Newton-Raphson iterative method, which can dynamically adapt to dimming curves of any complex shape without relying on pre-stored mapping tables or fitting polynomials, and precisely control the mapping accuracy through a preset error threshold, so that the error converges to any desired level.

[0078] Optionally, in some embodiments of this application, the method further includes: the vehicle system responds to the preset scene recognition result, calls the corresponding preset scene lighting strategy, and, in combination with vehicle status information, light intensity and action recognition result, performs graded adjustment of the lighting state of the supplementary light body.

[0079] The ambient light determination function of the supplementary light can be based on multi-level brightness assessment or continuous brightness assessment. The supplementary light control unit adjusts the output brightness of the supplementary light in stages or continuously based on the ambient light value collected by the ambient light sensor, combined with preset brightness curves, scene mode parameters, or user preference parameters. For example, the output brightness is higher when the environment is darker and lower when the environment is brighter, to adapt to different preset scenarios such as retrieving items from storage spaces, applying makeup in the car, camping lighting, and emergency lighting.

[0080] For example, the vehicle's infotainment system or fill light control unit can invoke the corresponding brightness and color temperature strategy in a makeup scenario. By combining the pre-calibrated ambient light brightness or skin tone presentation test results of different locations in the cabin, it can automatically adjust to a more suitable base value of brightness and color temperature parameters for makeup or selfies, thereby reducing problems such as overexposure, underexposure, or skin tone distortion in the fill light.

[0081] In camping mode, the vehicle's infotainment system or auxiliary light control unit can automatically adjust the brightness of the auxiliary light or ambient light by combining outdoor ambient brightness, power consumption strategy, user settings, and preset lighting curves, so as to avoid the lighting being too bright and dazzling or too dim and insufficient, while also taking into account battery life.

[0082] Infrared detection or other motion detection modules are not only used to determine whether there is a movement of approaching or searching, but can also combine the duration of the movement, the frequency of the movement, the trend of sensor signal changes, vehicle status, installation position or multi-sensor fusion results to perform more stable usage status identification of the current state, thereby reducing false triggering caused by luggage shaking, changes in obstruction, vehicle vibration, etc.

[0083] This application extends ambient light judgment from binary brightness judgment to multi-level or continuous brightness judgment, and combines scene mode parameters to adaptively adjust brightness and color temperature. It also extends action judgment from single trigger to multi-dimensional feature comprehensive judgment, enabling the fill light to adaptively adjust lighting parameters in different scenarios. This improves the fill light's environmental adaptability, scene specificity, and anti-interference ability in complex vehicle environments.
