Description

Technical Field

[0001] This invention relates to the field of automotive smart cockpit technology, and more particularly to a method for regulating the temperature and pressure of a display screen based on an MCU. Background Technology

[0002] With the rapid development of new energy vehicles and intelligent cockpit technologies, in-vehicle displays are no longer simply information display terminals, but key components integrating core functions such as human-machine interaction, vehicle control, and entertainment applications. Users have increasingly higher demands for the user experience of displays, especially in terms of touch comfort, response speed, and natural interaction. Under long-term operation or extreme environmental conditions, the surface temperature of displays will change significantly, and the sensitivity and feedback of touch operations will also be affected by hardware and the environment. Therefore, how to achieve adaptive adjustment of displays to temperature and pressure has become an important technological direction for improving the level of cockpit intelligence and user experience.

[0003] Currently, several methods exist for adjusting display temperature or touch pressure. A common approach involves using an independent temperature sensor to detect ambient temperature; when the temperature is too high, the system reduces screen brightness or disables some display functions to passively cool the screen. For touch pressure, traditional solutions often employ pressure detection chips based on capacitance or resistance changes, setting fixed pressure thresholds to determine whether a click or swipe operation is performed. These methods are typically managed centrally by a central processing unit (CPU) or graphics processing unit (GPU), with temperature and pressure adjustments handled by different control logics or controllers, operating independently.

[0004] In summary, the temperature and pressure regulation of existing in-vehicle displays are independent of each other, lacking a unified acquisition and collaborative processing mechanism based on the same MCU; at the same time, they cannot adaptively adjust touch sensitivity according to individual user operating habits, resulting in inconsistent touch experiences for different users. Summary of the Invention

[0005] The purpose of this invention is to provide a method for regulating the temperature and pressure of a display screen based on an MCU, which solves the technical problems of existing vehicle display screens where temperature and pressure regulation are independent, lack of a collaborative processing mechanism based on the same MCU, and inability to adaptively adjust touch sensitivity according to individual user habits.

[0006] To achieve the above objectives, the present invention provides a method for regulating the temperature and pressure of a display screen based on an MCU, the method comprising the following steps: Acquiring temperature and pressure data: The MCU collects screen surface temperature data in real time through a screen temperature sensor integrated on the display, collects in-vehicle ambient temperature data in real time through an ambient temperature sensor installed in the vehicle, and collects touch point pressure data in real time through a pressure sensor array integrated on the display. Temperature regulation: The MCU determines the target temperature range corresponding to the current vehicle interior temperature based on the collected screen surface temperature data and vehicle interior ambient temperature data, and generates a temperature regulation command through a temperature control algorithm to control the heating execution unit or heat dissipation execution unit of the display screen to work, so that the surface temperature of the display screen is adjusted to the target temperature range. Pressure regulation: When the MCU determines that the surface temperature of the display screen has reached the target temperature range, the MCU identifies the current user's touch pressure characteristics through a pressure regulation algorithm based on the collected touch point pressure data, and dynamically adjusts the touch response sensitivity parameters of the display screen accordingly, so that different users can obtain a consistent touch response experience under different pressure levels. Command output: The MCU sends the processed temperature and pressure regulation results to the secondary controller for execution via the communication bus.

[0007] In the temperature adjustment step, the MCU determines the target temperature range corresponding to the current vehicle interior temperature based on the collected screen surface temperature data and vehicle interior ambient temperature data. When the ambient temperature inside the vehicle is higher than the first ambient temperature threshold, the MCU determines that the current environment is high-temperature and selects a target temperature range with a lower temperature to meet the user's need for a cool touch in a high-temperature environment. When the ambient temperature inside the vehicle is lower than the second ambient temperature threshold, the MCU determines that the current environment is low and selects a target temperature range that is slightly higher to meet the user's need for a warm touch in a low-temperature environment. When the ambient temperature inside the vehicle is between the second ambient temperature threshold and the first ambient temperature threshold, the MCU selects the intermediate temperature range.

[0008] In the temperature adjustment step, the first ambient temperature threshold is a preset value within the range of 32℃-35℃, and the target temperature range for the slightly lower temperature is 20℃-22℃; the second ambient temperature threshold is a preset value within the range of 10℃-15℃, and the target temperature range for the slightly higher temperature is 25℃-27℃; the intermediate temperature range is 22℃-25℃.

[0009] The temperature regulation step further includes user preference adaptive learning: The MCU records the user's manual adjustment behavior under different in-vehicle ambient temperatures. When it detects that the user has actively adjusted the screen temperature in the same direction multiple times under the same ambient temperature conditions, the MCU automatically updates the target temperature range corresponding to that ambient temperature. Specifically, when a user adjusts the screen temperature to below the current low-temperature target temperature range more than a preset number of times in a high-temperature environment, the MCU further reduces the target temperature range corresponding to that ambient temperature; when a user adjusts the screen temperature to above the current high-temperature target temperature range more than a preset number of times in a low-temperature environment, the MCU further increases the target temperature range corresponding to that ambient temperature.

[0010] The specific content of the pressure regulation step is as follows: The MCU determines whether the surface temperature of the display screen has reached the target temperature range; When the surface temperature of the display screen reaches the target temperature range, the MCU performs the following operations: The MCU continuously collects touch point pressure data within a preset time period and records the touch point pressure value corresponding to each valid touch; The MCU calculates the average touch point pressure value based on the recorded pressure values ​​of multiple touch points; The MCU compares the average touch point pressure value with a first pressure threshold and a second pressure threshold, wherein the first pressure threshold is less than the second pressure threshold; When the average touch point pressure value is lower than the first pressure threshold, the MCU determines that the current user is a light-touch user and increases the touch response sensitivity, reducing the minimum pressure required to trigger an effective touch to the first sensitivity level. When the average touch point pressure value is higher than the second pressure threshold, the MCU determines that the current user is a heavy-press user and reduces the touch response sensitivity, increasing the minimum pressure required to trigger an effective touch to the second sensitivity level. When the average touch point pressure value is greater than or equal to the first pressure threshold and less than or equal to the second pressure threshold, the MCU determines that the current user is a standard user and keeps the current touch response sensitivity unchanged. When the surface temperature of the display screen does not reach the target temperature range, the MCU does not perform the above operation and uses the preset default sensitivity parameter as the touch response sensitivity.

[0011] In the pressure adjustment step, the preset time period is a preset value within the range of 30 seconds to 5 minutes; A valid touch is a touch event in which the pressure value at the touch point is greater than or equal to the minimum pressure required to trigger a valid touch and the touch duration is greater than a preset time threshold.

[0012] In the pressure adjustment step, the first pressure threshold is a preset value within the range of 0.6 Newtons to 0.8 Newtons, and the second pressure threshold is a preset value within the range of 1.2 Newtons to 1.5 Newtons. The minimum pressure required to trigger a valid touch corresponding to the first sensitivity level is a preset value within the range of 0.4 Newtons to 0.6 Newtons; The minimum pressure required to trigger a valid touch at the second sensitivity level is a preset value within the range of 1.0 Newton to 1.3 Newton. The minimum pressure required to trigger an effective touch, corresponding to the default sensitivity parameter, is a preset value within the range of 0.8 Newtons to 1.0 Newtons.

[0013] The pressure regulation step further includes storing and loading user pressure characteristics: The MCU associates the identified user touch pressure characteristics with the corresponding user identifier and stores them in non-volatile memory; When the MCU detects that the same user is using the device again, it directly loads the touch response sensitivity parameters corresponding to that user from the non-volatile memory, without having to re-execute the calculation and comparison of the average touch point pressure value.

[0014] In the pressure regulation step, when the surface temperature of the display screen fluctuates within the target temperature range, the MCU handles the situation as follows: When the surface temperature of the display screen fluctuates within the target temperature range but never exceeds that range, the MCU maintains the pressure regulation operation it is currently performing. When the surface temperature of the display briefly exceeds the target temperature range and then quickly returns to normal, the MCU pauses the execution of the pressure regulation operation, uses the default sensitivity parameters, and resumes the execution of the pressure regulation operation after the temperature stabilizes and returns to the target temperature range and remains stable for a preset duration. The preset stabilization time is a preset value within the range of 5 to 30 seconds.

[0015] This invention discloses a method for regulating the temperature and pressure of a display screen based on an MCU. In terms of temperature regulation, the MCU dynamically determines the target temperature range based on the ambient temperature inside the vehicle and controls the heating or cooling unit in a closed loop, allowing the screen surface temperature to actively adapt to environmental changes. Furthermore, the method uses whether the screen temperature reaches the target range as a trigger condition, initiating user-specific habit recognition only after the temperature reaches the target. Touch response sensitivity is dynamically adjusted based on collected touch point pressure data. Therefore, this technical solution not only solves the resource redundancy and response delay problems caused by independent temperature and pressure regulation but also achieves adaptive pressure regulation based on user operating habits, significantly improving the consistency of touch experience across different environments and users.

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0017] Figure 1 This is a flowchart of the steps of the MCU-based display temperature and pressure adjustment method provided by the present invention. Detailed Implementation

[0018] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0019] Please see Figure 1 This invention provides a method for regulating the temperature and pressure of a display screen based on an MCU, the method comprising the following steps: S1. Acquiring temperature and pressure data: The MCU acquires screen surface temperature data in real time through the screen temperature sensor integrated on the display screen, acquires in-vehicle ambient temperature data in real time through the ambient temperature sensor set in the vehicle, and acquires touch point pressure data in real time through the pressure sensor array integrated on the display screen. S2. Temperature regulation: The MCU determines the target temperature range corresponding to the current vehicle interior temperature based on the collected screen surface temperature data and vehicle interior ambient temperature data, and generates a temperature regulation command through a temperature control algorithm to control the heating execution unit or heat dissipation execution unit of the display screen to work, so that the surface temperature of the display screen is adjusted to the target temperature range. S3. Pressure Adjustment: When the MCU determines that the surface temperature of the display screen has reached the target temperature range, the MCU identifies the current user's touch pressure characteristics through a pressure adjustment algorithm based on the collected touch point pressure data, and dynamically adjusts the touch response sensitivity parameters of the display screen accordingly, so that different users can obtain a consistent touch response experience under different pressure levels. S4, Instruction Output: The MCU sends the processed temperature and pressure regulation results to the secondary controller for execution via the communication bus.

[0020] In this embodiment, regarding temperature regulation, the MCU dynamically determines the target temperature range based on the ambient temperature inside the vehicle and controls the heating or cooling units in a closed loop, allowing the screen surface temperature to proactively adapt to environmental changes. Furthermore, the system uses whether the screen temperature reaches the target range as a trigger condition, initiating user-specific habit recognition only after the temperature reaches the target. Touch response sensitivity is dynamically adjusted based on collected touch point pressure data. Therefore, this technical solution not only solves the resource redundancy and response delay problems caused by independent temperature and pressure regulation but also achieves adaptive pressure regulation based on user operating habits, significantly improving the consistency of touch experience across different environments and users.

[0021] Furthermore, in the temperature adjustment step, the MCU determines the specific content of the target temperature range corresponding to the current vehicle interior temperature based on the collected screen surface temperature data and vehicle interior ambient temperature data. When the ambient temperature inside the vehicle is higher than the first ambient temperature threshold, the MCU determines that the current environment is high-temperature and selects a target temperature range with a lower temperature to meet the user's need for a cool touch in a high-temperature environment. When the ambient temperature inside the vehicle is lower than the second ambient temperature threshold, the MCU determines that the current environment is low and selects a target temperature range that is slightly higher to meet the user's need for a warm touch in a low-temperature environment. When the ambient temperature inside the vehicle is between the second ambient temperature threshold and the first ambient temperature threshold, the MCU selects the intermediate temperature range.

[0022] Furthermore, in the temperature adjustment step, the first ambient temperature threshold is a preset value within the range of 32℃-35℃, and the target temperature range for the slightly lower temperature is 20℃-22℃; the second ambient temperature threshold is a preset value within the range of 10℃-15℃, and the target temperature range for the slightly higher temperature is 25℃-27℃; the intermediate temperature range is 22℃-25℃.

[0023] In this embodiment, the MCU internally stores a first ambient temperature threshold (e.g., 32°C) and a second ambient temperature threshold (e.g., 15°C). When the in-vehicle ambient temperature sensor detects a current in-vehicle temperature of 38°C, the MCU determines that it is in a high-temperature environment and automatically selects a slightly lower target temperature range of 20°C-22°C as the adjustment target, maintaining the screen surface temperature within this range, providing a cool sensation when the user touches it. When the in-vehicle ambient temperature is 5°C, the MCU determines that it is in a low-temperature environment and automatically selects a slightly higher target temperature range of 25°C-27°C, providing a warm sensation when the user touches it. When the in-vehicle ambient temperature is 25°C, the MCU determines that it is in a normal temperature environment and selects a neutral temperature range of 22°C-25°C, providing a neutral and comfortable sensation when the user touches it.

[0024] Furthermore, the temperature regulation step also includes user preference adaptive learning: The MCU records the user's manual adjustment behavior under different in-vehicle ambient temperatures. When it detects that the user has actively adjusted the screen temperature in the same direction multiple times under the same ambient temperature conditions, the MCU automatically updates the target temperature range corresponding to that ambient temperature. Specifically, when a user adjusts the screen temperature to below the current low-temperature target temperature range more than a preset number of times in a high-temperature environment, the MCU further reduces the target temperature range corresponding to that ambient temperature; when a user adjusts the screen temperature to above the current high-temperature target temperature range more than a preset number of times in a low-temperature environment, the MCU further increases the target temperature range corresponding to that ambient temperature.

[0025] In this implementation, the MCU continuously records the user's manual temperature adjustment operations. For example, in a high-temperature summer environment (in-vehicle ambient temperature above 35°C), the system's default target temperature range for lower temperatures is 20°C-22°C. If the user repeatedly and manually lowers the screen temperature to 19°C, the MCU recognizes this behavior and automatically updates the target temperature range corresponding to the ambient temperature, adjusting the lower temperature range to 19°C-21°C. Similarly, in a low-temperature winter environment, if the user repeatedly and manually raises the screen temperature to 28°C, the MCU automatically updates the higher temperature range to 26°C-28°C, achieving adaptive learning of the user's temperature preferences.

[0026] Furthermore, the specific details of the pressure regulation step are as follows: The MCU determines whether the surface temperature of the display screen has reached the target temperature range; When the surface temperature of the display screen reaches the target temperature range, the MCU performs the following operations: The MCU continuously collects touch point pressure data within a preset time period and records the touch point pressure value corresponding to each valid touch; The MCU calculates the average touch point pressure value based on the recorded pressure values ​​of multiple touch points; The MCU compares the average touch point pressure value with a first pressure threshold and a second pressure threshold, wherein the first pressure threshold is less than the second pressure threshold; When the average touch point pressure value is lower than the first pressure threshold, the MCU determines that the current user is a light-touch user and increases the touch response sensitivity, reducing the minimum pressure required to trigger an effective touch to the first sensitivity level. When the average touch point pressure value is higher than the second pressure threshold, the MCU determines that the current user is a heavy-press user and reduces the touch response sensitivity, increasing the minimum pressure required to trigger an effective touch to the second sensitivity level. When the average touch point pressure value is greater than or equal to the first pressure threshold and less than or equal to the second pressure threshold, the MCU determines that the current user is a standard user and keeps the current touch response sensitivity unchanged. When the surface temperature of the display screen does not reach the target temperature range, the MCU does not perform the above operation and uses the preset default sensitivity parameter as the touch response sensitivity.

[0027] The preset time period is a preset value within the range of 30 seconds to 5 minutes; The effective touch is a touch event in which the pressure value of the touch point is greater than or equal to the minimum pressure required to trigger the effective touch and the touch duration is greater than a preset time threshold. The first pressure threshold is a preset value within the range of 0.6 Newtons to 0.8 Newtons, and the second pressure threshold is a preset value within the range of 1.2 Newtons to 1.5 Newtons; The minimum pressure required to trigger a valid touch corresponding to the first sensitivity level is a preset value within the range of 0.4 Newtons to 0.6 Newtons; The minimum pressure required to trigger a valid touch at the second sensitivity level is a preset value within the range of 1.0 Newton to 1.3 Newton. The minimum pressure required to trigger an effective touch, corresponding to the default sensitivity parameter, is a preset value within the range of 0.8 Newtons to 1.0 Newtons.

[0028] In this embodiment, we take a user accustomed to light touch operation as an example. Once the display surface temperature stabilizes within the target temperature range (e.g., 22℃-25℃), the MCU begins pressure adjustment. The MCU collects pressure data from 20 effective touch points within 30 seconds, calculating an average touch point pressure value of 0.65 Newtons. The MCU compares this value with a first pressure threshold of 0.7 Newtons and a second pressure threshold of 1.2 Newtons. Determining that 0.65 Newtons is lower than the first pressure threshold, the MCU identifies the user as a light-touch user and increases the touch response sensitivity, reducing the minimum pressure required to trigger an effective touch from the default 0.9 Newtons to 0.5 Newtons (the first sensitivity level). Afterward, the user only needs a light pressing pressure to trigger the touch response, achieving a smooth and comfortable operating experience.

[0029] For users who are accustomed to pressing hard, the MCU collects and calculates an average touch point pressure value of 1.4 Newtons, which is higher than the second pressure threshold of 1.2 Newtons. They are identified as hard-pressing users, and the minimum pressure required to trigger a valid touch is increased to 1.2 Newtons (second sensitivity level) to avoid accidental triggering caused by unintentional touch.

[0030] When the surface temperature of the display screen deviates from the target temperature range briefly due to the start / stop of the air conditioner or exposure to sunlight, the MCU pauses the pressure regulation operation, restores the default sensitivity parameter of 0.9 Newtons, and resumes pressure regulation after the temperature returns to the target range.

[0031] Furthermore, the pressure regulation step also includes storing and loading user pressure characteristics: The MCU associates the identified user touch pressure characteristics with the corresponding user identifier and stores them in non-volatile memory; When the MCU detects that the same user is using the device again, it directly loads the touch response sensitivity parameters corresponding to that user from the non-volatile memory, without having to re-execute the calculation and comparison of the average touch point pressure value.

[0032] In this embodiment, taking a family car scenario as an example, the husband is accustomed to heavy pressing (average pressure 1.4 Newtons), while the wife is accustomed to light touching (average pressure 0.65 Newtons). After the MCU initially identifies the husband's pressure characteristics, it associates his pressure characteristic profile with the user identifier "User1" and stores it in non-volatile memory. When the husband gets in the car again, the MCU quickly collects several touch point pressure data points, identifies the pressure characteristics as matching the stored "User1," and directly loads the corresponding touch response sensitivity parameters (trigger threshold 1.2 Newtons) from memory, without needing to recalculate the average value or make comparison adjustments, achieving a millisecond-level fast response. Similarly, when the wife uses the car, the MCU automatically loads her corresponding sensitivity parameters (trigger threshold 0.5 Newtons), achieving seamless switching between multiple users.

[0033] Furthermore, in the pressure regulation step, when the display surface temperature fluctuates within the target temperature range, the MCU handles the situation as follows: When the surface temperature of the display screen fluctuates within the target temperature range but never exceeds that range, the MCU maintains the pressure regulation operation it is currently performing. When the surface temperature of the display briefly exceeds the target temperature range and then quickly returns to normal, the MCU pauses the execution of the pressure regulation operation, uses the default sensitivity parameters, and resumes the execution of the pressure regulation operation after the temperature stabilizes and returns to the target temperature range and remains stable for a preset duration. The preset stabilization time is a preset value within the range of 5 to 30 seconds.

[0034] In this embodiment, a real-world scenario during vehicle operation is considered. When the vehicle moves from a shaded area into direct sunlight, the screen surface temperature may rapidly rise from 23°C to 26°C (still on the edge of the target range of 22°C-25°C). At this point, the MCU determines that although the temperature fluctuates, it has not exceeded the range, and maintains the current pressure adjustment operation unchanged, so the user is unaware of it. When the vehicle is briefly exposed to strong sunlight, causing the screen surface temperature to rapidly rise from 24°C to 27.5°C (exceeding the 25°C upper limit), and then quickly drop back to 24°C due to air conditioning cooling, the MCU detects that the temperature has exceeded the range and immediately pauses the pressure adjustment operation, using the default sensitivity parameter of 0.9 Newtons. After the temperature stabilizes back to 24°C and remains stable for 10 seconds (preset stabilization time), the MCU resumes the pressure adjustment operation, reloading the user pressure characteristic data before the pause, ensuring the stability and reliability of the pressure adjustment function.

[0035] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
