Description

Technical Field

[0001] This application relates to the field of new energy power supply technology, and more specifically, to a method, device, equipment, and medium for powering the central control screen of a vehicle. Background Technology

[0002] With the rapid development of intelligent electric vehicles, in-vehicle central control screens are evolving towards larger sizes, higher brightness, and multi-functional integration (such as navigation, entertainment, and vehicle control), resulting in a significant increase in energy consumption. To isolate the direct impact of the central control screen's power consumption on the vehicle's battery, existing technologies typically equip the screen with a separate built-in battery, which directly powers the screen.

[0003] However, this approach introduces a new systemic problem: the screen's built-in battery constitutes an additional load that must be periodically charged by the vehicle's main battery. Its energy relies entirely on replenishment from the main battery while the vehicle is in motion or charging, effectively adding a forced, periodic high-power charging step between the screen and the main battery. This leads to energy conversion and storage losses, and also increases the burden on system management.

[0004] Therefore, a solution is needed. Summary of the Invention

The second control module is used to control the solar power generation system and the screen's built-in battery to work together to power the central control screen if the power generation is greater than or equal to the first power generation threshold and less than the second power generation threshold. The third control module is used to control the solar power generation system to supply power to the central control screen and the screen's built-in battery if the power generation is greater than or equal to the second power generation threshold, and to control the main battery to stop supplying power to the screen's built-in battery.

[0013] In one feasible implementation, the device further includes: The record acquisition module is used to acquire the historical power generation records of the solar panel after the vehicle is detected to start. The attitude determination module is used to determine the optimal power generation attitude based on the historical power generation records. An attitude adjustment module is used to control the adjustment subsystem to adjust the solar panel to the optimal power generation attitude.

[0014] In one feasible implementation, the central control screen has a built-in light detection device; The device further includes: The light intensity data acquisition module is used to acquire the real-time detection data output by the light detection device; An orientation determination module is used to determine the incident direction of sunlight based on the real-time detection data; The attitude determination module is used to determine the optimal power generation attitude based on the historical power generation records, for the following purposes: Based on the historical power generation records, the optimal power generation posture adapted to the direction of sunlight incidence is periodically determined, and the posture of the solar panel is adjusted according to the changes in the direction of sunlight incidence.

[0021] Furthermore, an adjustment gap is provided between the solar panel and the back panel of the central control screen, and an adjustment subsystem is arranged in this gap. This structural design allows the solar panel to adjust its posture independently of the central control screen, and it will not cause the central control screen to change its posture when tracking sunlight, thereby ensuring that users have a stable screen viewing experience while driving.

[0022] Based on this, this method dynamically and intelligently switches between three working modes: "pure battery power supply", "photovoltaic-storage coordinated power supply" and "pure solar power supply and charging" by real-time detection of the current power generation of the solar power system and comparison with the preset first power generation threshold and second power generation threshold.

[0023] Compared to existing technologies where the screen's built-in battery relies entirely on the vehicle's main battery for charging, this application introduces the aforementioned solar power generation system and intelligent power supply strategy to provide an incremental, local energy source for the central control screen system. This not only significantly reduces the frequency and intensity of the screen's built-in battery's dependence on the vehicle's main battery for charging, alleviating energy conversion losses and system management burdens caused by periodic charging, but also enables the central control screen system to self-supply energy when there is sufficient sunlight, thereby reducing the consumption of the vehicle's overall electrical energy at the system level.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0032] With the rapid development of intelligent electric vehicles, in-vehicle central control screens are evolving towards larger sizes, higher brightness, and multi-functional integration (such as navigation, entertainment, and vehicle control), resulting in a significant increase in energy consumption. To isolate the direct impact of the central control screen's power consumption on the vehicle's battery, existing technologies typically equip the screen with a separate built-in battery, which directly powers the screen.

[0033] However, this approach introduces a new systemic problem: the screen's built-in battery constitutes an additional load that must be periodically charged by the vehicle's main battery. Its energy relies entirely on replenishment from the main battery while the vehicle is in motion or charging, effectively adding a forced, periodic high-power charging step between the screen and the main battery. This leads to energy conversion and storage losses, and also increases the burden on system management.

[0034] Based on this, embodiments of this application provide a method, apparatus, device, and medium for powering a vehicle's central control screen, which will be described below through embodiments.

[0035] To facilitate understanding of this embodiment, a method for powering a vehicle's central control screen, disclosed in this application, is first described. This method is applied to the vehicle's control terminal (which can be called a control system; for ease of description, it will be referred to as the system below). The control terminal, the central control screen, and the solar power generation system are electrically connected. The central control screen has a built-in battery, and the vehicle's main battery powers the built-in battery. Figure 1The diagram shows a top view of the central control screen and the solar power generation system. The solar power generation system includes a solar panel 101 and an adjustment subsystem 102 for adjusting the posture of the solar panel. The size difference between the solar panel 101 and the central control screen 103 is less than a preset difference (e.g., they are the same size, both 28 inches). The solar power generation system is located on the back panel of the central control screen 103. The solar panel 101 is in an initial posture (e.g., ...). Figure 1 In the posture shown, it is set parallel to the back panel of the central control screen 103, and a preset adjustment gap (assumed to be 1-2cm) is maintained between the two, and the adjustment subsystem 102 is set in the adjustment gap.

[0036] Furthermore, Figure 2 This illustration shows an installation diagram of a central control screen and a solar power generation system in a vehicle, as provided in an embodiment of this application. Figure 2 In the side view shown, the central control screen 103 is still located in the first row of the vehicle. A solar power generation system (solar panel 101 and regulation subsystem 102) is set behind the central control screen 103, so that the solar panel 101 can receive the outside light through the windshield and generate solar power.

[0037] Next, the method of the embodiments of this application will be described. Figure 3 A flowchart illustrating a power supply method for a vehicle's central control screen according to an embodiment of this application is shown, such as... Figure 3 As shown, the method includes the following steps: Step 301: After the central control screen is turned on, detect the current power generation of the solar power generation system.

[0038] When the vehicle starts and enters an operable state, this embodiment of the application initiates a monitoring process for energy supply. After the central control screen is activated, since the central control screen requires power, it needs to obtain the power generation of the solar power generation system behind the back panel, that is, the actual electrical power generated by the solar power panel at this moment.

[0039] The "power generation" mentioned here does not refer to the cumulative value over a day or a period of time, but rather to the instantaneous electrical power output of the solar panel at the moment of testing, based on the current sunlight conditions, its own angle, and its operating status. This value changes in real time, and its level directly reflects the efficiency of converting solar energy into electrical energy at that specific time and place.

[0040] Power generation can be detected using a sensor module installed in the solar panel's output circuit. This module continuously reads voltage and current signals and calculates the instantaneous power value. This value becomes the fundamental basis for all subsequent power supply logic judgments. Since the control terminal is electrically connected to the solar power generation system, it can obtain the power generation detected by the sensor module.

[0041] The reason for choosing to perform the test after the central control screen is turned on is that the entire power supply chain is activated at this time. The solar panel, the screen's built-in battery, and the central control screen itself constitute a complete closed-loop system with energy to be allocated. The detected power generation will serve as a "command signal" to determine how energy flows within this closed loop. For example, the detected power generation may be low in the early morning or on a cloudy day; while on a sunny day at noon with a suitable panel angle, the power generation may reach a very high level. This embodiment of the application makes the power supply decision most suitable for the current environment based on the perception of this real-time state, rather than relying on any preset, fixed schedule or simple on / off switches.

[0042] Step 302: If the power generation is less than the first power generation threshold, control the built-in battery of the screen to supply power to the central control screen.

[0043] The first power generation threshold is determined based on the average power required to maintain the operation of the central control screen. For example, if the average power consumption of the central control screen under typical operating conditions is approximately 9 watts, the first power generation threshold can be set to 10 watts, slightly higher than this value. This setting aims to establish a reliable power supply switching boundary. When the detected real-time power generation is lower than a preset, lower power threshold (i.e., the first power generation threshold), this solution determines that the current output of the solar power system is insufficient to independently support the operation of the central control screen. This situation typically occurs in environments with low light, such as early morning, dusk, rainy weather, or when a vehicle enters a tunnel or underground parking garage.

[0044] At this time, the solar power system will temporarily cease its primary responsibility of directly powering the central control screen. The entire power demand of the central control screen will be met by its built-in battery. The built-in battery begins to release its stored energy to ensure the normal operation of the screen's functions is unaffected by changes in ambient light. It is important to note that the power in the built-in battery is supplied by the vehicle's main battery at this time.

[0045] The core logic of this mode is to prioritize the absolute reliability of power supply. The specific value of the first power generation threshold can be calibrated and optimized based on the actual power consumption characteristics of the screen and the system's stability requirements. Essentially, it draws a clear baseline between "utilizing solar energy as much as possible" and "ensuring basic operation." When the power generation falls below this line, the system will automatically switch to a robust mode powered entirely by the screen's built-in battery.

[0046] Meanwhile, in this mode, the meager electrical energy generated by the solar power system, while insufficient to directly power the screen, can still be channeled for other auxiliary purposes depending on the specific circuit design. For example, it can power low-power monitoring circuits within the system, assist the main battery in charging the screen's built-in battery, or logically be temporarily not used. Crucially, the power supply responsibility for the central control screen is clearly and entirely borne by the screen's built-in battery at this time.

[0047] Step 303: If the power generation is greater than or equal to the first power generation threshold and less than the second power generation threshold, then control the solar power generation system and the screen's built-in battery to work together to power the central control screen.

[0048] When the detected (real-time) power generation falls between the first and second power generation thresholds, it indicates that the output capacity of the solar power system is sufficient to cover the basic operating needs of the central control screen, with a slight surplus, but it has not yet reached a level sufficient to simultaneously and efficiently support screen operation and battery charging. For example, if the average power consumption of the central control screen is 9 watts and the effective charging power requirement of the screen's built-in battery is 5 watts, then the second power generation threshold can be set at around 14 watts.

[0049] Within this power generation range, this solution employs a collaborative power supply strategy. The electricity generated by the solar power system will serve as the primary, but not the sole, power source, directly supporting the current operation of the central control screen. Simultaneously, the screen's built-in battery will continue to operate as part of the power supply circuit, sharing the load with the solar power system. This collaboration can involve sharing the total load, or the solar power output can handle the basic load while the screen's built-in battery is responsible for handling any sudden peak power consumption that may occur.

[0050] This design consideration is to maximize the direct utilization of clean electricity generated in real-time, minimizing the consumption of energy stored in batteries, especially in situations where solar output is "sufficient but not abundant." It allows solar power to assume the primary responsibility for immediate power supply, while the screen's built-in battery takes on a secondary and buffering role, with its discharge rate significantly reduced, potentially even approaching zero discharge. This helps extend the battery's continuous operating time after a single charge and slows its aging. At this point, since the power generation has not yet reached the second power generation threshold, the system typically does not actively initiate a charging cycle for the screen's built-in battery, but instead prioritizes ensuring the immediate supply to the screen's load.

[0051] Step 304: If the power generation is greater than or equal to the second power generation threshold, control the solar power generation system to supply power to the central control screen and the screen's built-in battery, and control the main battery to stop supplying power to the screen's built-in battery.

[0052] When the detected real-time power generation reaches or exceeds the second power generation threshold, it indicates that the output capacity of the solar power generation system is already in a very sufficient state. At this time, the electricity generated by the solar panels can not only fully meet the power requirements of the central control screen in real time, but also has enough surplus to effectively charge the screen's built-in battery.

[0053] In this scenario, the solution employs a highly efficient energy distribution mode. The solar power system becomes the sole energy source and core of the entire central control screen's power supply architecture. Its output is divided into two paths: one directly supplies the central control screen, ensuring a stable power supply for its current operation; the other flows to the screen's built-in battery to replenish its power.

[0054] Simultaneously, a crucial control command is executed: the vehicle's main battery stops supplying power to the screen's built-in battery. This means that the task of charging the screen's built-in battery, originally undertaken by the vehicle's overall energy system, is completely relieved. The central control screen and its built-in battery achieve a degree of "self-sufficiency" in energy, forming a localized, solar-powered microgrid. This not only directly reduces the demand for energy from the vehicle's main battery, lowering overall vehicle energy consumption, but also avoids the efficiency loss caused by the secondary energy conversion from the main battery to the screen's built-in battery.

[0055] This mode typically occurs in environments with ideal lighting conditions, such as when the vehicle is parked facing south on a sunny day, and / or when the solar panels are adjusted to their optimal position for receiving sunlight. This approach achieves the design goal of utilizing ambient energy to power onboard electronic devices and reducing the load on the vehicle's powertrain.

[0056] This application provides a method, apparatus, device, and medium for powering a vehicle's central control screen. By installing a solar power generation system on the back panel of the central control screen, it achieves efficient utilization of external solar energy. The size of the solar panel is matched to the central control screen, ensuring that its integration does not interfere with the user's driving visibility.

[0057] Furthermore, an adjustment gap is provided between the solar panel and the back panel of the central control screen, and an adjustment subsystem is arranged in this gap. This structural design allows the solar panel to adjust its posture independently of the central control screen, and it will not cause the central control screen to change its posture when tracking sunlight, thereby ensuring that users have a stable screen viewing experience while driving.

[0058] Based on this, this method dynamically and intelligently switches between three working modes: "pure battery power supply", "photovoltaic-storage coordinated power supply" and "pure solar power supply and charging" by real-time detection of the current power generation of the solar power system and comparison with the preset first power generation threshold and second power generation threshold.

[0059] Compared to existing technologies where the screen's built-in battery relies entirely on the vehicle's main battery for charging, this application introduces the aforementioned solar power generation system and intelligent power supply strategy to provide an incremental, local energy source for the central control screen system. This not only significantly reduces the frequency and intensity of the screen's built-in battery's dependence on the vehicle's main battery for charging, alleviating energy conversion losses and system management burdens caused by periodic charging, but also enables the central control screen system to self-supply energy when there is sufficient sunlight, thereby reducing the consumption of the vehicle's overall electrical energy at the system level.

[0060] In one feasible implementation, the method further includes: After detecting vehicle startup, the system acquires the historical power generation records of the solar panel; determines the optimal power generation posture based on the historical power generation records; and controls the adjustment subsystem to adjust the solar panel to the optimal power generation posture.

[0061] After vehicle startup is detected, the power generation records of the solar panels over a past period (e.g., the past few days or a similar time period) can be obtained. By analyzing this historical data, the solar panel attitude angle that maximizes power generation at specific times, locations, or weather conditions can be determined. Based on these patterns, a predicted "optimal power generation attitude" for the current moment is determined, and accordingly, the adjustment subsystem is controlled to adjust the solar panels to this optimal power generation attitude at the start of driving.

[0062] The purpose of this pre-adjustment strategy is to enable the solar panels to quickly enter a relatively efficient power generation state after the vehicle is started, rather than starting the search from the default position, thereby shortening the response time for the system to reach optimal power generation efficiency and improving the energy capture capability in the initial stage.

[0063] Regarding how to determine the sun's position for accurate tracking, this solution provides several feasible technical approaches. For example, in one feasible implementation, existing environmental sensing elements in the central control screen area can be utilized (saving costs and reducing resource waste). For instance, the central control screen itself may have a built-in light intensity sensor for automatically adjusting screen brightness based on ambient light. In this case, the method further includes: Acquire real-time detection data output by the light detection device; determine the incident direction of sunlight based on the real-time detection data. Then, determine the optimal power generation posture based on the historical power generation records, including: Based on the historical power generation records, the optimal power generation posture adapted to the direction of sunlight incidence is periodically determined, and the posture of the solar panel is adjusted according to the changes in the direction of sunlight incidence.

[0064] In other words, the embodiments of this application can acquire real-time detection data output by the sensor, and indirectly calculate the relative incident direction of sunlight by comparing and analyzing multi-directional light intensity information. In this case, the aforementioned process of determining the optimal attitude based on historical power generation records can be combined with real-time sensing. The system can periodically (e.g., once per second or every few seconds) predict and calculate a theoretical value of the "optimal power generation attitude" that is adapted to the current estimated sun position, based on the solar motion patterns summarized from historical records. At the same time, this theoretical attitude is fine-tuned and calibrated by combining the solar incident direction information fed back in real time by the light detection device. In this way, the attitude adjustment of the solar panel can be dynamically carried out based on the continuous tracking of changes in the solar incident direction, forming a composite control strategy of "prediction first, perception correction", thereby maintaining the optimal relative angle between the solar panel and the sunlight more smoothly and accurately, maximizing the power generation efficiency throughout the day.

[0065] It's important to note that acquiring sunlight direction data isn't limited to reusing the screen's existing light intensity sensor. For more accurate and faster tracking, a dedicated light detection device can be configured separately for the solar power system. For example, a dedicated sensor capable of detecting differences in light intensity from multiple directions could be used, or a visual positioning unit capable of directly measuring the sun's relative azimuth and altitude angles could be employed.

[0066] The main advantage of using dedicated sensors lies in improving the system's control efficiency and response speed. Dedicated sensors can be optimized for the needs of solar tracking, and their sampling frequency, detection angle, and installation angle can all be set independently to obtain the key parameters needed to calculate the sun's position more directly. This avoids data interference or scheduling delays that may occur when sharing sensors with functions such as screen backlight adjustment, allowing the adjustment subsystem to drive the solar panels to align with the sun more quickly and accurately, thereby maintaining high power generation efficiency more stably in dynamic driving environments.

[0067] This design choice reflects the flexibility of this solution in implementation: it can utilize the vehicle's existing hardware resources to reduce costs, or it can pursue higher performance by adding dedicated components. Regardless of the sensing method used, the ultimate goal is to serve the same core control logic—that is, to dynamically adjust the solar panel attitude based on changes in the sun's position to continuously optimize light capture efficiency.

[0068] In one alternative implementation, the adjustment subsystem includes: a micro stepper motor and a dual-axis mechanical mechanism; the micro stepper motor drives the solar panel through the dual-axis mechanical structure to adjust the attitude of the solar panel.

[0069] In this implementation, the micro stepper motor serves as the core actuator, responsible for providing precise rotational power. Its output is transmitted and converted through a specially designed dual-axis mechanical mechanism. This dual-axis mechanism typically comprises two sets of spatially orthogonal rotating axes; for example, one set controls the solar panel's left-right rotation around a vertical axis (azimuth adjustment), and the other controls its up-down pitch around a horizontal axis (elevation adjustment). The micro stepper motor is connected to these two sets of axes via gears, linkages, or direct drive, thereby decomposing and converting the motor's precise angular displacement into attitude changes of the solar panel in two dimensions.

[0070] The advantage of this design lies in achieving high-precision and high-reliability control of the solar panel's orientation. The micro stepper motor itself is characterized by precise positioning, rapid response, and ease of digital control, making it ideal for small-amplitude, frequent correction movements. The dual-axis mechanical mechanism provides the necessary degrees of freedom and structural support, ensuring that the solar panel can flexibly and stably point towards the target direction throughout the entire design range. The entire adjustment process is smooth and virtually silent, causing no disturbance to the vehicle's interior environment. By receiving commands from the control unit, this adjustment subsystem can drive the solar panel to continuously align with the sun, thereby maximizing the capture of solar energy in various parking and driving positions of the vehicle.

[0071] It should be noted that the adjustment action here is performed completely independently. The solar panel is connected to the dual-axis mechanical mechanism via its own bracket. This entire drive and support structure is arranged within the adjustment gap reserved between the solar panel and the back panel of the central control screen, and is independent of the fixed housing of the central control screen.

[0072] The physical existence of this adjustment gap is key to achieving mechanical decoupling. It ensures that the solar panel and its adjustment mechanism have the necessary, unobstructed space for movement during operation. When the micro stepper motor drives the dual-axis mechanism, thereby causing the solar panel to rotate left and right or tilt up and down, all its mechanical movements are contained within this gap and are not transmitted to the housing of the central control screen.

[0073] As an independent display module, the central control screen's posture and position are fixed by the vehicle's original installation structure on the center console, and will not change in any way due to adjustments to the solar panels. This ensures the absolute protection of the user's visual experience and operating habits. This physical isolation, achieved through preset adjustment gaps, is a crucial design principle that ensures the integration of high-performance solar tracking functions without sacrificing the stability of core human-machine interaction.

[0074] In one feasible implementation, controlling the solar power generation system and the screen's built-in battery to work together to power the central control screen includes: The solar power generation system is controlled to supply power to the central control screen; when the relationship between the power consumption of the central control screen and the power generation is detected to meet the preset power shortage conditions, the solar power generation system is assisted in supplying power to the central control screen through the built-in battery of the screen.

[0075] In this mode, the system first establishes the solar power generation system as the primary power source. The electricity generated by the solar panels is preferentially and directly delivered to the central control screen, striving to meet the basic operational needs of the screen by relying on real-time captured solar energy.

[0076] Meanwhile, the system continuously monitors the relationship between the actual power consumption of the central control screen (i.e., load power) and the real-time power generation of the solar power system (i.e., supply power). When the relationship between the two meets a preset "power shortage condition," the system will trigger a coordinated action. For example, a typical power shortage condition could be "the instantaneous power consumption of the screen exceeds the current solar power generation," which usually occurs when the screen performs high-power operations (such as instantly increasing brightness, starting high-performance navigation rendering, or processing complex graphics).

[0077] Once the condition is met, the system will immediately activate the screen's built-in battery. The built-in battery does not continuously discharge; instead, it acts as a dynamic, responsive auxiliary power source, precisely supplementing the energy deficit when there is a momentary shortage in solar power. This synergy is essentially a hybrid power supply strategy of "solar power priority, with the built-in battery providing immediate backup." It maximizes the use of immediate solar energy while ensuring stable and sufficient power supply through the rapid response of the built-in battery, enabling the central control screen to receive seamless power support when facing fluctuating loads, thus achieving an optimized balance between energy saving and performance.

[0078] Based on the same technical concept, this application embodiment also provides a vehicle central control screen power supply device, the device is mounted on the vehicle's control terminal, the control terminal, the central control screen, and the solar power generation system are electrically connected respectively; the central control screen is provided with a screen built-in battery, and the vehicle's main battery powers the screen built-in battery.

[0088] The device further includes: The light intensity data acquisition module is used to acquire the real-time detection data output by the light detection device.

[0089] The direction determination module is used to determine the incident direction of sunlight based on the real-time detection data.

[0090] The attitude determination module is used to determine the optimal power generation attitude based on the historical power generation records, for the following purposes: Based on the historical power generation records, the optimal power generation posture adapted to the direction of sunlight incidence is periodically determined, and the posture of the solar panel is adjusted according to the changes in the direction of sunlight incidence.

[0091] In one feasible implementation, the regulating subsystem includes: a miniature stepper motor and a dual-axis mechanical mechanism.

[0092] The micro stepper motor drives the solar panel through the dual-axis mechanical structure to adjust the posture of the solar panel.

[0093] In one feasible implementation, the second control module is used to control the solar power generation system and the screen's built-in battery to work together to power the central control screen, for the following purposes: Control the solar power generation system to supply power to the central control screen.
