[0002] With the rapid development of new energy vehicles and intelligent driving technology, modern vehicles have evolved from traditional means of transportation into mobile living spaces that integrate intelligence, personalization, and emotional connection. In intelligent cockpit systems, the suspension system and ambient lighting system, as core configurations for enhancing the driving experience, respectively play key roles in optimizing vehicle dynamic performance and creating a cabin atmosphere.

[0003] The suspension system, by adjusting suspension stiffness and height, can adapt to different road conditions and improve ride comfort; while the ambient lighting system provides users with emotional and contextual visual feedback through changes in color, brightness, and dynamic effects. However, the coordinated control capabilities of these two systems in current vehicles still have significant shortcomings. Summary of the Invention

[0032] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0033] With the continuous advancement of the automotive industry, automobiles are no longer merely transportation tools, but have gradually evolved into mobile living spaces integrating comfort, intelligence, and personalization. Improving the intelligent environment of the vehicle cabin is a crucial direction for enhancing user experience. In-vehicle comfort systems are evolving from single-function modules to multi-system collaborative control, integrating various sensing and execution units to achieve comprehensive control of the cabin environment. For example, in intelligent cockpit systems, the suspension system and ambient lighting system, as core configurations for enhancing the driving experience, respectively play key roles in optimizing vehicle dynamics and creating a conducive cabin atmosphere.

[0034] Suspension systems are increasingly used in mid-to-high-end vehicles. By adjusting the stiffness and damping characteristics of the suspension, they can effectively improve the ride smoothness and comfort of the vehicle under different road conditions. Suspension systems typically have multiple height adjustment modes to adapt to various driving scenarios such as urban roads, highway driving, or complex terrain. They can also adjust in real time based on parameters such as vehicle speed and body posture to optimize the dynamic performance of the entire vehicle. Ambient lighting systems have also become an important feature for enhancing cabin quality. Ambient lighting can create diverse visual atmospheres through color temperature, brightness, and dynamic changes to meet the emotional and sensory needs of users in different situations. Currently, some vehicles have implemented linked control between ambient lighting and music, door opening status, or driving mode, thereby enhancing the immersiveness and intuitiveness of human-machine interaction.

[0035] In related technologies, the state changes of the suspension system are usually only operated as an independent function of the chassis control layer. The important information reflecting the vehicle's driving posture, road condition adaptation or driving mode switching is not effectively transmitted to the visual interaction system in the cabin, so that the driver and passengers cannot perceive the actual working status of the suspension system through intuitive visual feedback.

[0036] For example, when the vehicle automatically lowers its height to enhance stability due to increased speed, or actively raises the ground clearance in off-road mode, the interior lighting system remains unchanged and fails to synchronously present the changes in the lighting environment that match the vehicle's physical posture, thus reducing the continuity and immersiveness of human-vehicle interaction.

[0037] Meanwhile, existing ambient lighting control systems are mostly based on preset scenarios or static signal triggers, lacking the ability to respond to real-time dynamic conditions of the vehicle. Especially during continuous suspension adjustments or transient changes in operating conditions, they cannot achieve synchronous evolution of light color, brightness, or dynamic effects. This not only limits the cabin environment system's ability to comprehensively present the overall vehicle status but also weakens the user's perception of the vehicle's level of intelligence.

[0038] Therefore, there is an urgent need to establish a technical approach that can convert the suspension operating state into perceptible visual signals to fill the technical gaps in the current intelligent cockpit regarding the completeness of vehicle state feedback and multi-domain system collaborative control. This would allow the physical state of the vehicle suspension system (rigid, flexible, high, low, fast, slow) to be mapped in real time to the visual emotional language of the ambient lighting in the cabin (cold, warm, still, dynamic). Furthermore, the inventors propose to construct a dynamic linkage mechanism between the suspension system and the ambient lighting system, converting the physical state parameters of the vehicle suspension into the visual language of the cabin ambient lighting in real time. This would achieve deep synergy between the vehicle suspension state and user perception, enhancing the user's perceptual experience and emotional resonance.

[0039] The execution subject of this invention embodiment can be an electronic device with processing capabilities, such as an existing controller in a vehicle or a separately set controller. The controller can be an electronic control unit (ECU), a microcontroller unit (MCU), etc., and this invention embodiment is not limited thereto.

[0040] Figure 1 A flowchart of a first embodiment of the vehicle control method provided by the present invention is shown. Figure 1 As shown, the method includes the following steps:

[0041] Step 110: Obtain the state parameters of the suspension of each wheel of the vehicle.

[0042] The state parameters include at least one of the following: suspension damping mode, suspension height, and suspension height change rate.

[0043] For example, the vehicle can be a passenger car, a sports utility vehicle, or other intelligent connected vehicle equipped with a suspension system and a cabin ambient lighting system, and the embodiments of the present invention are not limited thereto.

[0044] Suspension refers to the general term for the elastic suspension system that connects the vehicle body and wheels in a vehicle. It can be configured independently for each wheel of the vehicle and is used to buffer road impacts and adjust the vehicle's posture. It should be noted that the specific type of suspension is not limited in the embodiments of this invention. Any suspension structure with active adjustment capability is applicable, such as air spring suspension, coil spring suspension, and other controllable suspensions.

[0045] State parameters are core characteristic parameters characterizing the real-time operating state of the suspension. Among them, the suspension damping mode refers to the stiffness or softness of the suspension dampers, reflecting the suspension's ability to absorb shocks. This damping mode can be, for example, soft, moderate, stiff, or firm, and can be characterized by the drive current of the damping adjustment valve, the pulse width modulation duty cycle, or the output setting of the damping controller. Suspension height refers to the relative vertical distance between the wheels and the vehicle body, characterizing the vehicle's elevation relative to the ground. The rate of change of suspension height refers to the magnitude of the change in suspension height per unit time, reflecting the speed of change in suspension height.

[0046] In one example, the suspension's state parameters can be obtained through various methods, such as real-time sensor acquisition, prediction of road conditions ahead, and learning of the user's historical driving habits.

[0047] For example, the vehicle obtains its current location information and driving route information in real time through the in-vehicle navigation module. When it detects that the user manually adjusts the suspension height and damping mode multiple times in the same driving route, the vehicle marks the route as a special route and stores the location information of the route and the corresponding user-defined suspension settings. When the vehicle subsequently travels to the special route again through navigation positioning, the electronic equipment automatically retrieves the stored suspension settings and uses them as the suspension status parameters.

[0048] Alternatively, status parameters can be collected through sensors. Taking suspension height as an example, a height sensor is placed near each wheel. The height sensor can be a linkage position sensor, a Hall displacement sensor, or an inductive displacement sensor, which outputs voltage signals, digital signals, or bus messages corresponding to the wheel suspension travel in real time. Electronic equipment can receive the height signals of each wheel through the vehicle communication bus and convert the raw signals into suspension height values.

[0049] Taking suspension damping mode as an example, the execution current, valve opening, pulse width modulation (PWM) duty cycle, or mode register state of the damping regulator can reflect the current damping mode of the shock absorber. For example, the electronic device can directly read from the suspension control unit, or it can analyze the current suspension damping mode by detecting the drive current of the suspension shock absorber. It can be understood that suspension damping adjustment can be achieved by driving the damping solenoid valve with PWM current. The magnitude of the drive current can be precisely controlled by changing the duty cycle of the PWM signal, thereby achieving stepless adjustment of the suspension damping. Furthermore, the electronic device can determine the softness or stiffness of the current suspension damping mode by detecting the drive current value of the damping solenoid valve in real time; where a larger drive current results in smaller suspension damping and a softer suspension operation, and a smaller drive current results in larger suspension damping and a stiffer suspension operation.

[0050] Taking the suspension height change rate as an example, the electronic device obtains the suspension height change rate by performing differential calculations on the continuously collected suspension height data.

[0051] State parameters can also be predicted from road conditions ahead. For example, obtain road condition information ahead; predict state parameters based on the road condition information ahead. Here, the road condition information ahead is determined based on navigation planning information or based on recognition by image acquisition equipment.

[0052] For example, forward road condition information refers to road surface features along the vehicle's path that can affect suspension attitude, including road undulations, potholes, speed bumps, slopes, and curves. Navigation planning information refers to road condition data included in the driving route planned by the in-vehicle navigation system based on the destination. Image acquisition equipment refers to the vehicle's forward-facing camera, radar, stereo vision components, or surround-view perception components; the acquired images, after being recognized by the in-vehicle controller, can extract road condition information such as slopes, curves, potholes, speed bumps, construction areas, or gravel roads. Predictive state parameters refer to the ability to anticipate and adjust the attitude of each wheel suspension based on forward road condition information, enabling proactive linkage of ambient lighting.

[0053] In one example, after path planning is completed, the in-vehicle navigation terminal can output road attribute information within a certain pre-aimed distance ahead. Combined with the vehicle's current speed, positioning results, and road slope model, it generates road condition information for the road ahead and sends it to the electronic device. Alternatively, when the image acquisition device identifies low-lying road surfaces, continuous undulating sections, or obstacles ahead, the image recognition results can be combined with the target category, location, and size output by the deep learning detection model to constitute road condition information for the road ahead. Then, based on the identified road condition information such as potholes and speed bumps, and combined with the vehicle's speed and suspension adjustment characteristics, the electronic device predicts the upcoming suspension height changes, damping adjustment requirements, and corresponding height change rates for each wheel, thus completing the prediction of the suspension state parameters for each wheel.

[0054] This approach acquires road condition information before the vehicle reaches complex road conditions and uses this information to predict suspension state parameters in advance. This transforms suspension control from a passive response to a feedforward prediction, thereby improving the timeliness and accuracy of suspension adjustments. Because the state parameters can be generated in advance, subsequent linkage control with ambient lighting can establish a correspondence before the suspension action occurs, reducing display lag and enhancing the perceptibility of the vehicle's dynamic state and the consistency of the cabin environment.

[0055] Optionally, the predicted state parameters have a higher priority than the real-time acquired state parameters. In other words, when a predicted state parameter is received, the ambient light is controlled based on the predicted state parameter; when no predicted state parameter is received, the real-time acquired state parameters are obtained.

[0056] In one possible implementation, the state parameters only include suspension height. In this case, the electronic device uses the height values ​​of each wheel as the core characterization of the suspension state, expressing the vehicle's rise and fall, and the relative height differences between the four wheels. In another possible implementation, the state parameters include suspension height and suspension damping mode. The electronic device can not only grasp changes in ground clearance but also identify whether the suspension is currently biased towards flexible damping or rigid support. In yet another possible implementation, the state parameters further include the suspension height change rate, thereby describing the dynamic trend of the suspension state, such as identifying whether the suspension corresponding to a particular wheel is rapidly rising, rapidly falling, or remaining stable. Based on the above acquisition process, the electronic device can form a set of state parameters including wheel identification, sampling timestamp, height value, damping mode, and change rate.

[0057] Step 120: Determine the lighting parameters of the ambient lights in the corresponding areas of each wheel based on the status parameters of each wheel.

[0058] For example, the ambient lighting corresponding to each wheel refers to the lighting area in the cabin that is associated with the wheel according to its spatial position. For example, the left front wheel corresponds to the ambient lighting area on the left front door panel of the driver's seat or the left side of the instrument panel, the right front wheel corresponds to the ambient lighting area on the right front door panel of the passenger seat or the right side of the instrument panel, the left rear wheel corresponds to the light strip area on the left rear door panel or the left side of the rear cabin, and the right rear wheel corresponds to the light strip area on the right rear door panel or the right side of the rear cabin.

[0059] Lighting parameters define the specific display characteristics of ambient lighting, and may include one or more of the following: color temperature, color category, brightness level, dynamic effects, and illumination duration. Color temperature characterizes the visual characteristics of the light, indicating whether it is cool or warm; brightness characterizes the light's intensity and can be expressed as a percentage, duty cycle, or drive current value; dynamic effects characterize the light's movement, such as light flow, pulse flashing, gradation, breathing, or constant illumination.

[0060] In some possible implementations, for each wheel, the electronic device can determine the lighting parameters of the ambient light corresponding to that wheel based on the wheel's suspension height. Specifically, it can first determine the current height offset of the wheel by subtracting a preset reference height from the wheel's suspension height. If the current height offset is greater than 0 (suspension raised), the brightness and color temperature of the ambient light corresponding to that wheel are increased by a preset ratio (the larger the offset, the greater the increase in brightness and color temperature), while the dynamic effect is determined to be "flowing from the lower part of the door panel to the upper middle part of the door panel," conforming to the posture of the suspension raised. If the current height offset is less than 0 (suspension lowered), the brightness and color temperature of the ambient light corresponding to that wheel are decreased by a preset ratio (the larger the absolute value of the offset, the greater the decrease in brightness and color temperature), while the dynamic effect is determined to be "flowing from the upper middle part of the door panel to the lower part of the door panel," conforming to the posture of the suspension lowered. If the current height offset is 0 (suspension at the reference height), the brightness is set to the preset reference brightness, the color temperature is set to the preset reference color temperature, and the dynamic effect is set to static constant light, ensuring that the lighting effect is accurately matched with the suspension height state.

[0061] In some possible implementations, for each wheel, electronic devices can determine the lighting parameters of the ambient lighting in the corresponding area based on the suspension damping mode of that wheel. Specifically, the corresponding stiffness coefficient can be determined first based on the suspension damping mode to precisely adjust the color temperature. Then, based on the mapping relationship between the stiffness coefficient and color temperature, brightness, and dynamic effects, the lighting parameters of the ambient lighting in the corresponding area of ​​that wheel can be determined. For example, the smaller the stiffness coefficient (softer damping), the warmer the color temperature (e.g., 3000K-4000K); the larger the stiffness coefficient (harder damping), the cooler the color temperature (e.g., 5000K-6000K); if the damping mode is moderate, the color temperature is set to neutral white (e.g., 4000K-5000K), ensuring that the color temperature directly corresponds to the stiffness of the suspension damping, allowing passengers to perceive the suspension damping mode through the warmth or coolness of the lighting.

[0062] In some possible implementations, if the rate of change of the suspension height of the target wheel is determined to be greater than or equal to a preset threshold, the lighting parameters of the ambient light in the area corresponding to the target wheel are set to the target color and the target dynamic effect.

[0063] For example, the target wheel refers to the wheel whose suspension height change rate meets the judgment condition (greater than or equal to a preset threshold). This could be any one of the four wheels: front left, front right, rear left, or rear right. The suspension height change rate refers to the magnitude of the change in suspension height of the target wheel per unit time, reflecting the speed of suspension height change. The larger the value, the more drastic the change in suspension posture. The preset threshold is a critical value set before the vehicle leaves the factory based on suspension performance and safety warning requirements. It is used to distinguish between normal and transient operating conditions (such as driving over potholes, rapid acceleration, rapid deceleration, and unilateral bumps). It is understood that this preset threshold can be adaptively adjusted according to the vehicle's driving mode; for example, the value of the preset threshold may differ between Sport mode and Comfort mode.

[0064] The target color is a preset warning color used to indicate transient operating conditions. It must be eye-catching and easily identifiable to visually remind drivers and passengers that the vehicle is currently experiencing a drastic change in suspension posture. The target dynamic effect is a preset lighting animation effect that matches the warning color, used to enhance the warning and avoid confusion with regular lighting dynamic effects. Setting the lighting parameters refers to directly switching the current color and dynamic effect of the ambient light in the area corresponding to the target wheel to the preset target color and target dynamic effect.

[0065] For example, for each wheel, the electronic device can perform differential calculations on continuously collected suspension height data to obtain the suspension height change rate of each wheel. Simultaneously, it calls a preset threshold and compares the suspension height change rate of each wheel with the preset threshold one by one. When the suspension height change rate of a certain wheel (i.e., the target wheel) is detected to be greater than or equal to the preset threshold, it is determined that the target wheel is in a transient condition. The lighting parameters of the ambient light in the area corresponding to the target wheel are then set, such as setting the target color to red (a conspicuous warning color, distinct from conventional warm and cool color temperatures), and setting the target dynamic effect to high-frequency pulse flashing (e.g., flashing 3-5 times per second, with the pulse amplitude changing from dark to bright and then back to dark, enhancing the warning effect). Understandably, in this implementation, the switching process requires no waiting time, responding in real-time to changes in suspension status, ensuring that occupants can quickly perceive the transient attitude changes of the target wheel through the lighting, while not affecting the normal display status of the ambient lights in areas corresponding to other non-target wheels.

[0066] With this approach, ambient lighting no longer switches based solely on static scenes, but can respond instantly to rapid changes in the suspension, allowing users to more intuitively perceive changes in vehicle posture and chassis adjustment status, improving the real-time performance and consistency of cockpit interaction, and enhancing the safety alerts and contextual expression capabilities during vehicle operation.

[0067] In some possible implementations, the electronic device can establish a mapping relationship between state parameters and lighting parameters, and generate lighting parameters for each wheel's corresponding area based on this mapping relationship. The mapping relationship can be implemented using a lookup table, a rule engine, or a function operation. Taking the function operation method as an example, a functional relationship can be set between the lighting parameter set K and the suspension damping mode DampMode, suspension height DampHeight, and suspension height change rate DampRate, i.e., K = f(DampMode, DampHeight, DampRate). Here, the function f is used to convert the chassis physical state into a visual representation. If the suspension height is lowered and the damping mode is stiffer, the function output can make the corresponding area of ​​light appear cooler, with higher contrast and a faster pace, to indicate that the vehicle is in a state that emphasizes handling stability. If the suspension height is raised and the damping mode is softer, the function output can make the corresponding area of ​​light appear warmer, with lower brightness and a slower gradient, to indicate that the vehicle is in a state that emphasizes comfort and passability. If the absolute value of the suspension height change rate is large, it indicates that the suspension is adjusting rapidly. The function output can increase the intensity of the dynamic effect, for example, by increasing the pulse frequency or shortening the gradient period, to enhance the user's perception of transient changes.

[0068] Optionally, to make the mapping results more closely match the vehicle's usage context, driving mode, vehicle environmental conditions, and user preference information can be introduced as constraints based on the state parameters. Driving modes can include Sport, Comfort, Standard, and Off-Road modes. When the vehicle is in Sport mode, the same suspension height change can be mapped to a more pronounced cool color tone and higher brightness to enhance the dynamic driving atmosphere; when the vehicle is in Comfort mode, the same suspension change can be mapped to a softer warm color tone and a smoother brightness change to avoid excessive visual stimulation. Vehicle environmental conditions can include information such as nighttime, rainy weather, tunnels, the number of occupants, and music playback status. Electronic devices can limit the upper limit of brightness, dynamic intensity, and color contrast based on the environmental conditions. For example, when driving at night, the upper limit of brightness can be lowered to reduce visual interference for the driver; in rainy weather or complex conditions, the proportion of warning colors can be increased to enhance the indication of the vehicle's dynamic status. User preference information can be derived from historical usage records. For example, if a user prefers warm color gradient feedback under specific road conditions, the electronic device can personalize the color and brightness parameters while maintaining the basic mapping rules.

[0069] Furthermore, to avoid frequent jumps in lighting parameters due to minor fluctuations in suspension status, a smooth transition process can be introduced during the lighting parameter calculation. After obtaining the lighting parameters at the current moment, the electronic device can perform linear interpolation, exponential smoothing, or limit updates based on the actual output parameters from the previous moment, thus ensuring continuous changes in color, brightness, and dynamic effects over time. Taking linear interpolation as an example, when the current brightness increases from 30 to 60, the electronic device does not switch directly within a single control cycle, but adjusts gradually in segmented increments over a preset transition time, thereby eliminating abrupt changes. For color changes, interpolation can also be performed in the RGB (Red, Green, Blue) space or HSV (Hue Saturation Value) space, making the transition between warm and cool tones more natural. For dynamic effects, by setting a minimum hold time and switching threshold, repeated switching between pulses, gradients, and constant brightness due to fluctuations in state parameters near the threshold can be avoided. Thus, the lighting parameters of each wheel's corresponding area can not only accurately reflect the suspension status but also be expressed in a continuous, perceptible, and non-abrupt manner, thereby transforming the dynamic adjustment process of the chassis system into a stable and reliable visual mapping result.

[0070] Step 130: Based on the lighting parameters of the ambient lights in the corresponding areas of each wheel, control the display status of the ambient lights so that the display status of the ambient lights matches the status of the suspension.

[0071] For example, display status refers to the overall performance result of ambient lighting after it is actually lit, including the color, brightness, lighting sequence, dynamic change form, and spatial distribution of each zone light strip or light source. Display status matching means that the color temperature, brightness, dynamic effect, etc. of the ambient lighting are synchronized in real time with the status of the corresponding wheel suspension. That is, when the suspension status changes, the display effect of the ambient lighting in the corresponding area is also adjusted accordingly to ensure that the lighting effect can intuitively reflect the changes in the vehicle's posture.

[0072] In one example, the electronic device can generate lighting commands based on the lighting parameters of the ambient lights in the corresponding areas of each wheel. These commands include area identification, color temperature, color value, brightness value, dynamic effects, change cycle, and execution duration. The commands are then sent to the ambient light control module, which configures the LED drive current, PWM duty cycle, and channel timing for the corresponding areas. This ensures that the ambient lights in the front left, front right, rear left, and rear right areas present a visual effect consistent with the suspension state of the corresponding wheels. For instance, when the suspension height of the front left wheel decreases rapidly and the damping mode switches to a stiffer state, the front left area light can change from a neutral, constant brightness to a rapid, gradual blue transition. When the rear right wheel experiences a sudden increase in the rate of change of suspension height due to road impact, the rear right area light can briefly display a highly recognizable pulse effect. When the suspensions of all four wheels rise simultaneously with a small rate of change, the four areas of light can collectively present a consistent warm color with a slow transition, expressing the overall lifting of the vehicle's posture.

[0073] Optionally, if the electronic device predicts speed bumps, potholes or sharp turns ahead based on the navigation map, front-view camera or user's historical habits, it can obtain the status parameters in advance and pre-change the lighting display status of the corresponding area before the suspension is actually adjusted, forming a warning-style linkage to improve the user's anticipatory perception of the upcoming chassis actions of the vehicle.

[0074] By mapping the suspension status of each wheel to the corresponding visual area inside the cockpit respectively, the user can directly judge which part of the vehicle's suspension is being adjusted from the spatial distribution of the cockpit lights, thereby enhancing the intuitive understanding of the vehicle's attitude changes, load changes and road surface disturbances. Compared with the solution of uniformly changing the lights only based on the vehicle mode switch, this method can provide a more fine-grained and more real-time status expression and avoid the perception fragmentation caused by the general lighting feedback. Further, by controlling lighting parameters such as color, brightness and dynamic effects, the directionality, intensity and change speed of the suspension status can be expressed simultaneously, turning the chassis adjustment information from an invisible internal control quantity into a visual language that can be perceived by the driver and passengers. Thus, the originally separate control link between the suspension system and the ambient light system is打通, and a complete linkage mechanism from status acquisition, parameter mapping to visual execution is formed during the vehicle operation.

[0075] In this embodiment, by obtaining the status parameters of the suspensions of each wheel of the vehicle, combining the status parameters of each wheel to determine the lighting parameters of the ambient lights in the corresponding area, and then controlling the display status of the ambient lights according to the determined lighting parameters, the display status of the ambient lights is kept in line with the status of the suspension. This method realizes the precise linkage between the suspension status and the in-vehicle ambient lights, and relies on the independent status parameters of each wheel to achieve zoned lighting control, which can accurately capture the subtle changes in the body posture, enabling the passengers to directly perceive the working status of the vehicle suspension through the lights, realizing the deep coordination between the cockpit environment and the vehicle status, enhancing the user's perception experience and emotional resonance, and enhancing the intelligent experience of driving.

[0076] Figure 2 The flowchart of the second embodiment of the vehicle control method provided by the present invention is shown. As Figure 2 shown, the method includes the following steps:

[0077] Step 210: Obtain the status parameters of the suspensions of each wheel of the vehicle.

[0078] It should be noted that this step is similar to the前述 step 110 and will not be elaborated here.

[0079] Step 220: For each wheel, determine the current height offset of the wheel according to the difference between the suspension height of the wheel and the preset reference height.

[0080] For example, suspension height refers to the vertical distance between the suspension body and the wheel in real time for a single wheel. Figure 3 This diagram illustrates a suspension height variation method provided by the present invention. (Refer to...) Figure 3 As shown, the preset reference height is the standard suspension height set under normal driving conditions, serving as a reference for attitude judgment. The current height offset characterizes the degree of suspension rise or fall relative to the standard attitude; a positive offset indicates that the suspension has risen, such as... Figure 3 In H1; a negative offset indicates that the suspension is lowered, such as... Figure 3 H2 in it.

[0081] In one example, the electronic device subtracts the preset reference height from the real-time collected or predicted suspension height for each wheel, and calculates the difference, which is the current height offset of that wheel.

[0082] Step 230: Determine the current stiffness coefficient of the suspension damping of the wheel based on the suspension damping mode of the wheel.

[0083] For example, the suspension damping mode is a stepless adjustment mode for suspension stiffness achieved by driving the damping solenoid valve with PWM current. The damping stiffness can be determined by detecting the magnitude of the driving current. The current stiffness coefficient is a numerical coefficient used to quantify the degree of suspension damping stiffness; the larger the coefficient, the stiffer the suspension damping, and the smaller the coefficient, the softer the suspension damping.

[0084] In one example, for each wheel, the suspension damping mode is determined by detecting the PWM drive current value of the suspension damping solenoid valve. Different suspension damping modes correspond to different stiffness coefficients, thereby obtaining the current stiffness coefficient. For example, Table 1 shows a correspondence between suspension damping modes and stiffness coefficients provided by an embodiment of the present invention.

[0085] Table 1. Correspondence between suspension damping modes and stiffness coefficients

[0086]

[0087] Furthermore, the current stiffness coefficient can be determined based on the suspension damping mode, as shown in Table 1.

[0088] Step 240: Determine the lighting parameters of the ambient light in the area corresponding to the wheel based on the current height offset and the current hardness coefficient.

[0089] For example, for each wheel, the current height offset and current stiffness coefficient are input into a preset mapping model to obtain the lighting parameters of the ambient light in the corresponding area of ​​that wheel. These lighting parameters include at least one of brightness, color temperature, and dynamic effects. This mapping model can be implemented using a lookup table, a linear weighting method, or a nonlinear function to establish a stable correspondence between wheel attitude changes and lighting performance. For instance, when the suspension height of a wheel is increased and the damping mode is in a stiffer state, based on the mapping of the current height offset and current stiffness coefficient, the ambient light in the corresponding area can be controlled to have higher brightness and stronger dynamic changes to reflect that the wheel is in a state of enhanced support. When the suspension height is decreased and the damping mode is in a softer state, the ambient light in the corresponding area can be controlled to have lower brightness and gentler changes to reflect a comfortable cruising state. By jointly mapping the height offset and stiffness coefficient to the lighting parameters, the ambient light in the corresponding area of ​​each wheel can accurately reflect the combined characteristics of the suspension attitude and damping state, thereby improving the consistency between cabin visual feedback and chassis status.

[0090] In some possible implementations, the brightness and dynamic effects in the lighting parameters are determined based on the current height offset; the color temperature in the lighting parameters is determined based on the current height offset and the current hardness coefficient.

[0091] For example, brightness can be determined through a lookup table, piecewise function, or continuous mapping. Dynamic effects can be set based on the absolute value and magnitude of the current height offset. A gentle breathing effect can be used when the current height offset is small, a slow gradient effect when the current height offset is moderate, and a more pronounced pulse or flowing effect when the height offset is large, thus ensuring that the lighting changes in the wheel-corresponding area are consistent with the suspension movements. In this way, the ambient lighting in the wheel-corresponding area can more accurately reflect the real-time state of the suspension, enhancing the user's intuitive perception of vehicle attitude changes and improving the consistency and responsiveness of the cabin environment. Because brightness, dynamic effects, and color temperature are respectively correlated with different suspension parameters, the lighting output has higher distinguishability and interpretability, which helps to improve the problems of lag and limited expression in existing ambient lighting.

[0092] For example, when the current height offset is positive and increasing, it indicates a more significant increase in the suspension height relative to the reference height. The ambient lighting brightness is increased accordingly, and the dynamic effect is set to allow light to flow upwards to enhance the perceptibility of changes in vehicle posture. If the current height offset is negative and the absolute value is large, it indicates a more significant decrease in the suspension height relative to the reference height. The brightness of the ambient lighting in that area is reduced accordingly, and the dynamic effect is set to allow light to flow downwards from the upper part of the door panel. When the height offset is close to zero, the reference brightness and static constant illumination are maintained.

[0093] Determining the color temperature can take into account the current height offset and the current hardness coefficient. In one possible implementation, the electronic device can first input these two values ​​into a preset mapping model and then output the corresponding color temperature value. When the current hardness coefficient is high and the current height offset is large, the color temperature can be adjusted towards a cool white or bluish range to create a stronger sense of motion cues; when the current hardness coefficient is low and the current height offset is small, the color temperature can be adjusted towards a warm white or yellowish range to create a soothing and soft visual effect.

[0094] In another possible implementation, the current height coefficient of the suspension is determined based on the current height offset; and the color temperature is determined based on the current height coefficient and the current stiffness coefficient.

[0095] The current height coefficient is a dimensionless coefficient obtained by normalizing the height offset, used to quantify the impact of height changes on the color of the headlights. The current height coefficient of the suspension can be obtained by transforming the current height offset through a mapping function, enabling it to distinguish between rising, falling, or approaching a reference height. Based on this current height coefficient, combined with the current stiffness coefficient, the electronic equipment can determine the color temperature output through a preset lookup table or functional relationship. For example, it outputs a warmer color temperature when the vehicle body is raised and the suspension is softer, and a cooler color temperature when the vehicle body is lowered and the suspension is stiffer, ensuring that the color temperature is consistent with changes in vehicle attitude. In this way, changes in suspension height can first be converted into a more stable and calculable current height coefficient, which then works with the current stiffness coefficient to generate the color temperature, allowing the headlight output to simultaneously reflect vehicle attitude and suspension support characteristics. Since the color temperature is no longer directly driven by the original offset, the impact of sensor transient fluctuations on the headlight display can be reduced, improving display continuity and consistency. At the same time, mapping based on intermediate parameters also facilitates the unified configuration of color temperature rules for different vehicle models, different driving modes, and different cabin scenarios, thereby enhancing the adaptability and scalability of ambient lighting and suspension linkage.

[0096] In one possible implementation, the electronic device can divide the current height offset into multiple levels, each corresponding to a different current height coefficient, thereby generating continuous or discrete coefficient values. In another possible implementation, the current suspension travel ratio is determined based on the current height offset; when the current height offset is greater than 0, the current height coefficient is determined based on the current travel ratio and a first preset mapping relationship, where the first preset mapping relationship indicates a positive correlation between the travel ratio and the height coefficient; when the current height offset is less than 0, the current height coefficient is determined based on the current travel ratio and a second preset mapping relationship, where the second preset mapping relationship indicates a negative correlation between the travel ratio and the height coefficient.

[0097] The current travel ratio characterizes the proportion of suspension extension / retraction under current operating conditions. The first and second preset mapping relationships can be constructed using calibration tables, piecewise functions, or continuous functions. The current travel ratio can be determined based on the height offset and the maximum permissible suspension travel (e.g., ...). Figure 3 The ratio between L and L is calculated to ensure a unified normalized expression for different vehicle models or suspension structures.

[0098] For example, when the suspension is in a raised state, the current height offset is greater than 0, the current travel ratio increases, and the electronic device outputs a height coefficient that increases with the travel ratio according to a first preset mapping relationship to reflect the increase in suspension height. When the suspension is in a lowered state, the current height offset is less than 0, and after the change in the current travel ratio, the electronic device outputs a height coefficient with the opposite trend according to a second preset mapping relationship to reflect the change in the degree of suspension lowering. The mapping relationship can be implemented using linear interpolation, piecewise fitting, or nonlinear regression, and can be calibrated and configured according to suspension structural parameters, vehicle height range, and control accuracy requirements. In practical applications, this mapping module can also select other algorithm models, which are not limited in this embodiment of the invention.

[0099] Figure 4 A schematic diagram illustrating the relationship between travel ratio and height coefficient provided by the present invention is shown, as follows: Figure 4 As shown, the horizontal axis represents the travel ratio, which is the ratio of the current height offset to the maximum allowable suspension travel L, reflecting the degree of suspension adjustment. It should be noted that since the offset ranges from -L / 2 to +L / 2, multiplying it by 2 normalizes it to the 0-1 range. Therefore, for ease of calculation, the current height offset is multiplied by a coefficient of 2 to map it to the 0-1 range. Figure 4 The height coefficient is represented by 2H1 or 2H2. The vertical axis represents the height coefficient, ranging from MinH to MaxH. At the reference position (travel ratio of 0), the height coefficient is fixed at 1. The ascending curve represents the first preset mapping relationship, that is, when the suspension rises (the offset is positive), the larger the travel ratio (the higher the suspension rises), the higher the height coefficient Fh increases linearly, from 1 to MaxH; the descending curve represents the second preset mapping relationship, that is, when the suspension lowers (the offset is negative), the larger the travel ratio (the lower the suspension lowers), the higher the height coefficient Fh decreases linearly, from 1 to MinH.

[0100] Specifically, the electronic equipment can first divide the current height offset by the maximum permissible suspension travel to obtain the current travel ratio. Then, based on the sign of the current height offset, it selects different mapping relationships to output the current height coefficient. This allows different calculation paths to correspond to the two types of operating conditions: raising and lowering, avoiding control distortion caused by a uniform mapping. In this way, the physical height change of the suspension can be stably converted into a standardized height coefficient, improving the consistency and calibrability of parameter expression under different operating conditions. It also provides continuous and distinguishable input for subsequent lighting parameter calculations, thereby enhancing the matching accuracy between suspension status and cockpit visual feedback.

[0101] The mapping relationship between color temperature Kd and current height coefficient Fh and current hardness coefficient Fm can be expressed as: Kd=Kb×Fh×Fm; where Kb represents the base color temperature of the ambient light, which can be set by the user or be the default value calibrated.

[0102] Step 250: Perform linear interpolation on the lighting parameters of the ambient lights in the corresponding areas of adjacent wheels to obtain the lighting parameters of the ambient lights on the line connecting adjacent wheels.

[0103] For example, adjacent wheels refer to the front and rear wheels on the same side of the vehicle or the left and right wheels on the same axle. The line connecting adjacent wheels refers to the continuous light strip area of ​​the ambient lighting between the corresponding areas of two adjacent wheels. The lighting parameters of the ambient lights on the line connecting adjacent wheels are used to characterize the lighting parameters of the ambient lights between the corresponding areas of two adjacent wheels, so as to indicate the transition display state on the line. Its interpolation result can make the lighting effects of different areas transition continuously in space, avoiding abrupt changes at the boundary of the area.

[0104] Linear interpolation refers to performing numerical smoothing calculations between two defined lighting parameters to make the light strip effect coherent and natural.

[0105] In one example, the electronic control unit extracts the color temperature, brightness, and other lighting parameters of the ambient lights in the corresponding areas of the front and rear wheels on the same side, and performs numerical transition calculations on the light strip between the two areas according to a linear ratio to obtain the lighting parameters corresponding to each LED on the connecting line.

[0106] Step 260: Control the display status of the ambient lights based on the lighting parameters of the ambient lights in the corresponding areas of each wheel and the lighting parameters of the ambient lights on the connecting lines of adjacent wheels.

[0107] For example, the ambient lighting control module drives the entire ambient lighting in the vehicle to display based on the basic lighting parameters of the corresponding area of ​​each wheel and the lighting parameters obtained by interpolation between adjacent areas, so that the lighting effect is precisely matched with the suspension posture and there is no obvious separation between areas.

[0108] For example, when controlling the display status of ambient lighting, the ambient lighting control module uses the lighting parameters of the corresponding areas of each wheel as discrete control points, and the lighting parameters of the lines connecting adjacent wheels as intermediate transition control points, and drives the corresponding light strips to emit light according to the preset display mapping relationship. For the same wheel area, the light strip can present the main display effect consistent with the state of that wheel; for the line area between adjacent wheels, the transition display effect is output according to the interpolated parameters, so that the ambient lighting of the whole vehicle presents a smooth and connected light effect distribution in the circumferential or lateral direction. Figure 5 A schematic diagram of an ambient light provided by the present invention is shown, such as... Figure 5 As shown, taking four wheels as an example, the interior ambient lighting uses the positions of the four wheels as four execution base points, corresponding to the front left, front right, rear left, and rear right areas respectively. The color temperature of each base point is independently determined by the suspension state parameters of the corresponding wheel. When the color temperature of a certain base point changes, the color temperature of all LED beads on the ambient light strip segment between that base point and the adjacent base point is smoothly calculated according to the position ratio, so that the color temperature of adjacent areas presents a continuous gradient effect, avoiding abrupt changes or a disjointed feeling in the lighting.

[0109] In this way, ambient lighting no longer forms discrete bright spots only in the areas corresponding to the wheels, but can establish a continuous visual transition between adjacent areas, making the suspension status reflected in the cabin more natural and consistent. When the vehicle is in different road conditions or changes in posture, the spatial changes in lighting can also be updated synchronously, thereby enhancing the coherence of vehicle status prompts, the overall atmosphere of the cabin, and the user's perception of dynamic changes in the vehicle.

[0110] It should be noted that the overall color temperature of the ambient lighting can be dynamically adjusted in the following two ways, as detailed below:

[0111] The first method is based on color temperature adjustment using RGB LEDs. Specifically, the color temperature in the lighting parameters can be synthesized by controlling the number and brightness ratio of different colored LEDs. For example, an RGB LED set contains red, green, and blue LEDs. The warmth or coolness of the color temperature is determined by the proportion of red and blue LEDs: when the color temperature is warm, the number or brightness of red LEDs is increased, and the proportion of blue LEDs is decreased; when the color temperature is cool, the number or brightness of blue LEDs is increased, and the proportion of red LEDs is decreased. Green LEDs are mainly used to help balance the color. Through the combination and ratio of the three, a continuous color temperature change from warm white to cool white can be achieved. In one example, when matching a warm-toned scene with a softer suspension and lower ride height, the conduction ratio of red LEDs can be increased and the conduction ratio of blue LEDs can be decreased to synthesize a warm white light with a low color temperature. When matching a cool-toned scene with a stiffer suspension and higher ride height, the proportion of blue LEDs can be increased to synthesize a cool white light with a high color temperature. By dynamically adjusting the number and brightness of each color LED, a color temperature effect that matches the suspension status can be achieved.

[0112] The second approach involves adjusting the color temperature of a dedicated white light. Specifically, the color temperature parameters of the dedicated white light can be directly adjusted to achieve overall color temperature changes. For example, this solution uses a separate adjustable white light unit within the ambient light. The white light itself supports color temperature adjustment, and its color temperature can be directly controlled via a drive signal, without relying on the mixing of multiple color LEDs. The adjustment range covers warm white to cool white, and it can directly output light matching the target color temperature. In one example, after calculating the color temperature based on the state parameters, a corresponding drive signal is sent directly to the white light unit. The white light responds to the signal and adjusts its own color temperature, while simultaneously working with other RGB LEDs to create the overall color effect of the ambient light. Changes in the white light's color temperature directly affect the overall warm or cool tone of the light, achieving precise and continuous color temperature adjustment.

[0113] The two methods mentioned above can be used individually or in combination: for example, using an independent white light as the base color, and then using RGB light groups for color compensation and enhancement, ultimately achieving a color temperature effect that precisely matches the suspension status, ensuring that drivers and passengers can intuitively perceive changes in the working status of the vehicle suspension.

[0114] In this embodiment, by acquiring the state parameters of the suspension of each wheel, the height offset and stiffness coefficient are calculated respectively to determine the lighting parameters of the ambient lights in the corresponding areas. Then, linear interpolation is used to achieve a smooth transition of lights in adjacent areas. Finally, the ambient light display is controlled based on the lighting parameters of the ambient lights in the corresponding areas of each wheel and the lighting parameters of the ambient lights on the lines connecting adjacent wheels, achieving a refined linkage between the suspension state and the interior ambient lights. This method allows the ambient lights to present corresponding brightness, color temperature, and dynamic effects as the suspension height changes and damping is adjusted. The light transition is smooth and seamless, intuitively reflecting the vehicle's suspension working state and changes in vehicle body posture, enhancing the technological feel of the vehicle interior and the driving and riding interaction experience. At the same time, it eliminates the need for manual adjustment of the ambient lights, enhancing the intelligence and convenience of vehicle use.

[0115] Figure 6 A schematic diagram of the structure of an electronic device provided by the present invention is shown. Figure 7 The diagram illustrates a data flow method provided by the present invention. (Refer to...) Figure 6 and Figure 7 As shown, the electronic device includes a suspension state prediction module, a suspension state acquisition module, a lighting decision module, and an ambient lighting execution module. These modules work together to achieve linkage control between the suspension state and the interior ambient lighting.

[0116] The intelligent driving module identifies special road sections marked by the user through navigation and positioning, or identifies road conditions ahead through image acquisition equipment and navigation planning information, and sends the road conditions ahead or the special road section markings marked by the user to the suspension status prediction module.

[0117] The suspension actuator module is used to drive the suspension to complete the height and damping adjustment actions based on the predicted state parameters.

[0118] The suspension state prediction module is used to obtain suspension state parameters based on user driving habits according to special road segment markings, or to predict suspension state parameters based on road condition information ahead. For example, this module can identify a continuous bumpy road segment 100 meters ahead using an onboard camera, adjust the suspension drive current in advance to reduce suspension damping stiffness, and obtain state parameters; it can also identify special road segments where the user has manually adjusted the suspension multiple times using GPS positioning, and automatically match a preset suspension height setting; before the suspension execution module completes the adjustment, the suspension state prediction module sends the estimated state parameters to the lighting decision module, causing the ambient lights to respond in advance to achieve a road condition warning effect. Optionally, after acquiring complex road condition information ahead, the electronic device can generate a warning signal and send this warning signal along with the predicted state parameters to the lighting decision module, causing the ambient lights to respond in advance before the suspension changes, providing the user with a road condition change warning.

[0119] The suspension status acquisition module is used to acquire the status parameters of each wheel suspension in real time, including suspension height and suspension damping mode. For example, the suspension height is obtained by acquiring the relative vertical distance between the vehicle body and the wheel through a height sensor; the suspension damping mode is determined by detecting the PWM drive current value of the damping solenoid valve. The larger the drive current, the smaller the suspension damping and the softer the suspension; the smaller the drive current, the larger the suspension damping and the stiffer the suspension. At the same time, this module can combine the suspension height change rate and damping mode to identify transient conditions such as rapid cornering, rapid acceleration nose-up, or sudden braking nose-down, providing status basis for lighting control.

[0120] The lighting decision module receives estimated state parameters from the suspension prediction module and real-time state parameters from the suspension state acquisition module, and generates ambient lighting parameters based on a preset mapping relationship. For example, this module can receive a user-preset base color temperature Kb, determine the current height offset for each wheel based on the difference between the suspension height and the preset reference height, and thus determine the current height coefficient Fh. It also determines the current stiffness coefficient Fm based on the suspension damping mode, calculates the color temperature of the corresponding area's ambient light using the formula Kd=Kb×Fh×Fm, and determines the brightness and dynamic effect parameters based on the current height offset. Simultaneously, the module determines whether the vehicle is in a transient condition based on the suspension height change rate. If it is in a transient condition, the module can directly output the target color and target dynamic effect lighting parameters to provide a warning. Optionally, if the lighting decision module receives a warning signal, it uses the predicted state parameters to determine the lighting parameters; if it does not receive a warning signal, it uses the real-time acquired state parameters to determine the lighting parameters.

[0121] The ambient lighting execution module receives lighting parameters output by the lighting decision module and controls the display status of the ambient lighting inside the vehicle. For example, based on the lighting parameters of the corresponding areas of each wheel, the module drives the ambient lighting to present brightness, color temperature, and dynamic effects that match the suspension status; at the same time, it performs linear interpolation processing on the lighting parameters of the corresponding areas of adjacent wheels to achieve a smooth and natural transition of the light strips and avoid display discontinuities.

[0122] Throughout the entire process, the suspension state prediction module and the suspension state acquisition module provide forward-looking and real-time state parameters, respectively. The lighting decision module generates appropriate lighting control commands based on the two types of parameters. Finally, the ambient lighting execution module completes the display control, enabling the ambient lighting in the vehicle to be linked with the real-time and predicted states of the suspension. This allows drivers and passengers to intuitively perceive the vehicle's driving conditions and suspension attitude changes through the lighting, enhancing the intelligent driving experience and visual interaction.
