[0024] S1, the environment perception and dynamic adjustment module perceives the environment data and transmits it to the control module, the control module receives the data and issues a control instruction according to a preset algorithm, the environment perception and dynamic adjustment module receives the adjustment instruction of the control module, and dynamically adjusts the brightness and color temperature of the display screen;

[0025] S2, the energy recovery and reuse module transfers the recovered energy to the power management unit for storage and utilization, and receives feedback information from the power management unit to optimize the energy recovery process;

[0026] S3, the content optimization and compression module receives the content information from the display screen, transmits it to the display screen for display after optimization and compression, and receives the instruction of the control module to adjust the optimization strategy according to the current energy consumption status;

[0027] S4, the intelligent sleep and wake-up preheating module predicts the sleep and wake-up timing of the display screen according to the user's driving habits, sends corresponding instructions to the control module, and is responsible for preheating the display screen and related hardware during the wake-up process;

[0028] The term "preheating" here does not mean preheating of the engine or mechanical parts in the traditional sense, but a preparation or optimization measure for the display and related hardware during the wake-up process.

[0029] S5, the power management unit receives the power input from the energy recovery and reuse module, distributes the power to each module, monitors the power consumption of the system, and provides feedback to the control module;

[0030] S6. The display screen module receives data and instructions from the control module and the content optimization and compression module, displays corresponding content according to these instructions, and feeds back its own status information to the control module for dynamic adjustment.

[0031] Among them, the environmental perception and dynamic adjustment module includes an ambient light sensor, a temperature sensor and an infrared human body sensor. The infrared human body sensor detects whether the passenger is watching the display screen. The ambient light sensor uses a high-precision ambient light sensor to perceive the brightness changes of the surrounding environment in real time and pass the data to the control unit.

[0032] The use of high-precision ambient light sensors (such as BH1750, etc.) can sense the brightness changes of the surrounding environment in real time. The control unit dynamically adjusts the backlight brightness of the display according to the preset algorithm or machine learning model to ensure a comfortable visual experience under different lighting conditions while reducing unnecessary energy consumption; an integrated temperature sensor is used to monitor the temperature of the display and its surroundings. In a high temperature environment, the brightness of the display may be automatically reduced to reduce heat generation, and power consumption can be reduced by adjusting parameters such as the refresh rate. At the same time, the temperature sensor can also be integrated with the vehicle's air-conditioning system to achieve a more intelligent temperature control strategy; when the infrared human body sensor detects that no one is watching, the display can automatically reduce the brightness or enter sleep mode to save energy.

[0033] The integrated temperature sensor is PT100 and the infrared human body sensor is XH001.

[0034] Among them, thermocouple effect recovery, micro generator and energy management system, thermocouple effect recovery absorbs the heat generated by the display backlight LED during operation and converts it into electrical energy. The micro generator uses the kinetic energy of wheel rotation or braking to drive the micro generator to generate electricity and provide auxiliary power supply for the vehicle display system.

[0035] The model of the thermocouple is K-type thermocouple, and the small generator is specifically LC2000I.

[0036] The energy recovery and reuse module is connected to hardware such as the thermocouple effect recovery device and the micro generator, transfers the recovered energy to the power management unit for storage and utilization, receives feedback information from the power management unit, and optimizes the energy recovery process.

[0037] Among them, the content optimization and compression module includes content analysis, resolution and color depth adjustment, and encoding method optimization. Content analysis uses image processing and machine learning technology to analyze the content displayed on the vehicle display screen and identify text, pictures and videos. Resolution and color depth adjustment dynamically adjusts the resolution and color depth of the display screen according to the importance and complexity of the analyzed content.

[0038] The content optimization and compression module is closely related to the content analysis algorithm, encoding processing unit, etc. It receives content information from the display screen or external data source, and transmits it to the display screen for display after optimization and compression. At the same time, it receives instructions from the control module, adjusts the optimization strategy according to the current energy consumption status, and performs intelligent analysis and optimization processing on the content displayed on the vehicle display screen. It reduces energy consumption during data transmission and rendering by lowering the resolution, adjusting the color depth, or using efficient encoding algorithms.

[0039] Among them, the optimization of encoding methods includes using compression algorithms such as JPEG to encode static images, and using the HEVC high-efficiency video coding standard to compress video content.

[0040] Content analysis includes identifying different types of content such as text, images, and videos, and evaluating their importance and complexity. For non-critical information or background parts, resolution and color depth adjustment can be used to present lower resolution and color depth to reduce energy consumption during data transmission and rendering.

[0041] Starting from the content level, the energy consumption of the display screen is reduced through optimization and compression, and image processing and machine learning technologies are introduced to improve the accuracy and efficiency of content analysis.

[0042] Among them, the intelligent sleep and wake-up preheating module includes driving habit analysis, sleep and wake-up prediction and intelligent scheduling. The driving habit analysis uses machine learning algorithms to conduct in-depth analysis of the driver's driving habits. The sleep and wake-up prediction is specifically based on the analysis results of driving habits, predicting when the vehicle display may enter a sleep state or when it needs to be woken up. Intelligent scheduling is specifically to intelligently schedule the working status of the display according to the prediction results, and reduce unnecessary energy consumption and wake-up delays by optimizing the timing and process of sleep and wake-up.

[0043] By analyzing historical data (such as driving routes, driving time, display screen usage frequency, etc.), the driver's possible behavior patterns in the future are predicted. In particular, when it is predicted that the driver is about to reach the destination and park, the display screen can be automatically set to sleep mode; when it is predicted that the driver is about to start the vehicle, the display screen can be woken up in advance and related hardware can be preheated. By optimizing the timing and process of sleep and wake-up, unnecessary energy consumption and wake-up delays can be reduced.

[0044] By combining machine learning technology to achieve intelligent sleep and wake-up predictions, the energy management efficiency of the vehicle display system is improved, and by optimizing the timing and process of sleep and wake-up, more precise energy control is achieved.

[0045] Among them, the power management unit includes a power monitoring unit, a dynamic power allocation unit and an energy-saving strategy execution unit. The power monitoring unit monitors the power consumption of the vehicle display and its related hardware in real time, including current and voltage. The dynamic power allocation unit dynamically adjusts the power allocation strategy according to the current working status and load conditions of the vehicle display. The energy-saving strategy execution unit performs corresponding power management operations according to the preset energy-saving strategy or user-defined energy-saving mode.

[0046] The power monitoring unit detects and handles power anomalies to prevent increased energy consumption or equipment damage caused by power problems. The dynamic power allocation unit automatically reduces the power supply of related hardware when the display is in standby or dormant mode to reduce unnecessary energy consumption. At the same time, when the display needs high-performance operation, it provides sufficient power support in time to ensure stable operation of the system; when the vehicle is turned off or parked for a long time, the energy-saving strategy execution unit automatically puts the vehicle display and related hardware into low-power mode or completely power-off state; when the vehicle is started or the user needs to use the display, it quickly restores its normal working state.

[0047] It realizes accurate monitoring and dynamic management of the power consumption of the vehicle display and related hardware, improves power utilization efficiency, reduces the risk of increased energy consumption and equipment damage due to power problems, improves system stability and reliability, and provides a flexible energy-saving strategy execution mechanism to meet users' different energy-saving needs and usage scenarios.

[0048] Among them, the display screen module includes dynamic backlight adjustment and pixel-level brightness control. The display screen module can automatically adjust the backlight brightness according to the intensity of the ambient light to avoid unclear screen visibility under strong light. The pixel-level brightness control includes OLED display technology. The display screen module can achieve pixel-level brightness control and adjust the brightness of each pixel according to the actual situation of the display content.
