A method for controlling heating of automobile steering wheel

Abstract

The present invention relates to the technical field of steering wheel heating control, and discloses a method for controlling the heating of a car steering wheel, comprising: firstly collecting the temperature setting information when the driver uses the steering wheel heating, and counting the number of times each temperature is used to determine the driver's commonly used temperature as a benchmark. Subsequently, when the driver activates the steering wheel heating function, the system sets the temperature of the holding area to the commonly used temperature, and at the same time, performs temperature adjustment on the non-holding area, so that its temperature is higher or lower than the commonly used temperature, thereby forming a high temperature area, a commonly used temperature area and a low temperature area on the steering wheel. The system monitors the temperature changes of each area of ​​the steering wheel in real time. Once it detects that the driver has changed the holding position, it determines that the temperature of the area he enters is too high or too low, and divides the new holding area and adjusts the temperature control, so that the holding area presents a hot and cold alternating state, thereby guiding the driver to automatically restore the holding area of ​​the steering wheel to the commonly used area.

Description

Technical Field

[0001] The invention relates to the technical field of steering wheel heating control, in particular to a vehicle steering wheel heating control method. Background Art

[0002] With the development of intelligent vehicle technology, car comfort and driving experience have become one of the important factors to improve driver satisfaction, and steering wheel heating is a common and practical configuration. However, most steering wheel heating systems on the market currently only provide simple temperature settings and fail to make intelligent adjustments based on the driver's personalized needs and driving habits; this means that the system cannot adapt to the driver's temperature requirements in different driving states and environments, resulting in the heating effect being too strong or too weak, thus affecting driving comfort and safety.

[0003] The steering wheel heating control system in the prior art mainly relies on preset temperatures or simple manual temperature adjustment to meet the driver's needs, which is usually not adaptable to the driver's habits. For example, some systems only allow the driver to manually adjust the heating temperature, but cannot record the driver's commonly used settings or dynamically adjust according to the driver's needs; in addition, the temperature adjustment range provided by some systems is too simple, and may not take into account the driver's comfort or the influence of environmental factors, which can easily lead to a poor driving experience.

[0004] In addition, although the steering wheel heating system can provide heating function, the heating range and heating intensity of most products cannot intelligently adapt to the actual area where the driver holds his hands. For the area where the driver holds his hands for a long time, the temperature of the steering wheel may increase due to the wrapping of the palms, which may cause the driver to unconsciously shift the grip position of the steering wheel, causing the driver to change the grip position of the steering wheel to a position that is not often used, which not only affects driving comfort, but may also interfere with the driver's attention and even affect driving safety.

[0005] In addition, most existing heating control systems ignore the changes in the position of the driver's grip on the steering wheel, and usually do not detect whether the driver has changed the grip position. There are no corresponding handling measures for changes in the driver's grip position, which may cause the driver to drive in an uncommon grip position, thereby affecting driving safety.

[0006] In summary, the existing steering wheel heating control technology fails to effectively perform intelligent adjustment according to the driver's usage habits, and fails to fully consider the dynamic changes of the hand grip position, affecting the driving comfort and safety; for this reason, this method proposes a steering wheel heating control system that can be intelligently adjusted according to the driver's commonly used temperature and hand grip area to enhance the driver's driving experience.

[0073] Repeat steps S12-S22 until the adjustment area overlaps with the current use area, completing the second guidance temperature control strategy.

[0074] The present invention has the following beneficial effects:

[0075] 1. With the driver's consent, the temperature set when using the steering wheel heating function is fully collected within the preset collection period, so that the number of times each temperature is set can be systematically recorded; this data collection method enables the system to automatically determine and filter out the heating temperatures commonly used by the driver, thereby providing accurate benchmark parameters for subsequent intelligent heating control; using real historical data to establish a personalized temperature control model avoids the disadvantages of the traditional single preset mode; this strategy realizes the dynamic update and optimization of temperature control parameters, so that the system can respond quickly when facing different driving environments and driver's individual needs; at the same time, the information collection process reduces the driver's operating burden during manual adjustment; therefore, this strategy not only improves the adaptability and intelligence level of the system, but also provides a data basis for the implementation of the overall temperature control strategy.

[0076] 2. Automatically setting the temperature to the driver's commonly used temperature when the driver starts the steering wheel heating function reflects the advantages of intelligence and convenience. The design makes full use of the historical temperature data collected in the early stage, so that the temperature control state that the driver is accustomed to can be restored at the moment of system startup. This automatic recovery mechanism greatly simplifies the driver's operating process, allowing the driver to enjoy a comfortable experience without having to manually adjust the temperature frequently. At the same time, the automatic setting of the commonly used temperature enables the temperature control system to quickly match the driver's needs and reduce the discomfort caused by temperature deviation. This step also lays the foundation for subsequent regulation of temperature differences in different areas, making the overall temperature distribution of the steering wheel more ergonomic.

[0077] 3. By monitoring the temperature of each area of ​​the steering wheel in real time during driving, the dynamic perception and self-correction function of the temperature control system is realized; by continuously collecting temperature data of each area, the system can determine in real time whether the current heating state matches the driver's hand holding area; when it is detected that the temperature of two areas exceeds the normal temperature, the system quickly marks it as the current use area and triggers subsequent temperature adjustment measures; this real-time monitoring mechanism can capture temperature anomalies or local overheating in time, thereby avoiding discomfort or safety hazards caused by excessive temperature differences; at the same time, continuous data monitoring provides an important basis for the system's subsequent temperature guidance strategy, so that the temperature control strategy has a closed-loop feedback characteristic; this method not only improves the temperature control accuracy and response speed, but also actively adapts to the driver's adjustment of the grip position during driving; thus, the system ensures the driver's comfort while also enhancing safety and stability; this real-time monitoring and feedback mechanism embodies the advantages of adaptive and multi-level regulation of the intelligent temperature control system.

[0078] 4. Fine division of the steering wheel area is the key to ensuring the accuracy of temperature control. This process obtains the center points of the two areas in the current use area and connects them to form a dividing line, thereby dividing the steering wheel into an upper area and a lower area. In each area, the overlapping part with the current use area is eliminated to form area one and area two, so that the temperature control system can implement precise heating for each independent area. This area division method based on geometric centers and lines ensures the scientific nature and adaptability of steering wheel temperature control. It not only makes temperature control more detailed, but also ensures differentiated management of heating temperatures in different areas. At the same time, by clearly dividing the areas, the system can avoid temperature control overlap and adjustment errors, thereby improving the balance of temperature distribution. This method also provides a clear physical boundary for subsequent temperature guidance strategies, making the entire temperature control process more efficient and intelligent.

[0079] 5. The first temperature control strategy is used to accurately control the temperature of the non-driver gripping area on the steering wheel, and three different temperature distributions can be formed on the steering wheel, namely, the common temperature, the area above the common temperature and the area below the common temperature, so as to provide clear temperature indications for the subsequent driver to change the grip position; this design enables the system to detect the temperature level of the area the driver enters in real time after the driver changes the grip position, and quickly determine whether the current gripping area is higher or lower than the common temperature, thereby providing a basis for selecting and executing the first guiding temperature control strategy or the second guiding temperature control strategy; this multi-temperature distribution scheme not only realizes the hierarchical regulation of the overall temperature field of the steering wheel, but also ensures that when the driver adjusts the grip posture, the system can quickly respond and identify the temperature state of the new gripping area through temperature differentiation processing, so as to know whether the common temperature is high or low for the driver in the current environment, and then perform adaptive temperature adjustment and guidance. This method helps to ensure the driver's driving comfort and improve driving safety at the same time.

[0080] 6. The No. 1 guided temperature control strategy executed when the transfer area is in the No. 1 area fully demonstrates the advantages of zone guided regulation. In this strategy, by obtaining the center point of the transfer area and constructing the transfer dividing line, the steering wheel is further subdivided into the No. 1 divided area and the No. 2 divided area, so as to realize the refined management of local temperature control. By controlling the heating temperature of the No. 1 divided area within a certain proportion of the transfer temperature, while the temperature of the No. 2 divided area is kept at the transfer temperature level, the contrast between the hot and cold temperatures is obvious. This design enables the driver to sense the temperature imbalance when holding the wheel, so as to spontaneously adjust the holding position to restore the comfortable state, thereby guiding the driver's hand holding position back to the commonly used position. At the same time, the strategy continuously compares the adjustment area with the current use area during the continuous monitoring of temperature changes, ensuring the closed-loop feedback and continuous iterative optimization of temperature control. Zone guided regulation not only improves the temperature control response speed, but also ensures the driver's safety and comfort experience. The implementation of this strategy realizes dynamic temperature guidance and intelligent adjustment, thereby significantly improving the system's ability to adapt to temperature changes in the hand holding area.

[0081] 7. The No. 2 guided temperature control strategy executed when the transfer area is in the No. 2 area embodies a more obvious advantage in temperature gradient control. This strategy divides the steering wheel into the No. 1 and No. 2 areas by obtaining the center points of the transfer areas to form transfer dividing lines, and sets different heating temperatures for them respectively. In this process, the temperature of the No. 1 area is set to the transfer temperature, while the temperature of the No. 2 area is controlled at a higher multiple of the transfer temperature, thus forming a significant difference in temperature. This obvious temperature difference design provides the driver with an intuitive temperature guidance signal, prompting him to automatically adjust the grip position to achieve the most suitable temperature control state, thereby guiding the driver's hand holding the steering wheel back to the commonly used position. At the same time, the system can accurately compare the adjustment area with the current use area while constantly monitoring the temperature changes in each area, thereby ensuring the accuracy and continuity of the temperature control. This partitioned temperature gradient control method enables the temperature control system to meet the comfort requirements while also improving the overall operational safety and intelligent response level.

[0085] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0088] Set the duration for executing the information collection strategy, recorded as the collection cycle;

[0089] During the collection period, after obtaining the driver's consent, the driver's steering wheel usage information is collected, specifically:

[0090] Get the heating temperature set by the driver each time the steering wheel heating function is used;

[0091] Get the number of times each heating temperature is set respectively and compare them;

[0092] The heating temperatures that are set the most times are screened and recorded as the driver's commonly used temperatures; within the preset collection period, the temperatures set when using the steering wheel heating function are comprehensively collected with the driver's consent, so that the number of times each temperature is set can be systematically recorded; this data collection method allows the system to automatically determine and screen out the heating temperatures commonly used by the driver, thereby providing accurate benchmark parameters for subsequent intelligent heating control; using real historical data to establish a personalized temperature control model avoids the drawbacks of the traditional single preset mode; this strategy realizes the dynamic update and optimization of temperature control parameters, so that the system can respond quickly when facing different driving environments and driver's individual needs; at the same time, the information collection process reduces the driver's operational burden during manual adjustment; therefore, this strategy not only improves the adaptability and intelligence level of the system, but also provides a data basis for the implementation of the overall temperature control strategy.

[0093] After completing the information collection strategy, when the driver is driving the vehicle and uses the steering wheel heating function, the heating of the steering wheel is intelligently controlled, including:

[0094] When the steering wheel heating function is turned on, the heating temperature of the steering wheel is controlled to be equal to the commonly used temperature; when the driver starts the steering wheel heating function, the temperature is automatically set to the driver's commonly used temperature. This measure reflects the advantages of intelligence and convenience; the design makes full use of the historical temperature data collected in the early stage, so that the temperature control state that the driver is accustomed to is restored at the moment the system is started; this automatic recovery mechanism greatly simplifies the driver's operating process, allowing the driver to enjoy a comfortable experience without having to manually adjust the temperature frequently; at the same time, the automatic setting of the commonly used temperature enables the temperature control system to quickly match the driver's needs and reduce the discomfort caused by temperature deviation; this step also lays the foundation for subsequent regulation of temperature differences in different areas, making the overall temperature distribution of the steering wheel more ergonomic.

[0095] When the driver is using the steering wheel, the temperature of each area on the steering wheel is monitored;

[0096] When it is monitored that the temperature of two areas rises to a value higher than the normal temperature, the two areas are recorded as the current use areas;

[0097] The heating temperature of the currently used area on the steering wheel is controlled to be lowered so that the temperature of the currently used area is equal to the commonly used temperature, and the first temperature adjustment strategy is implemented for other areas on the steering wheel except the currently used area; by real-time monitoring of the temperature of each area of ​​the steering wheel during driving, the dynamic perception and self-correction function of the temperature control system is realized; by continuously collecting temperature data of each area, the system can judge in real time whether the current heating state matches the driver's hand holding area; when it is detected that the temperature of two areas exceeds the commonly used temperature, the system quickly marks them as the currently used areas and triggers subsequent temperature adjustment measures; this real-time monitoring mechanism can capture temperature anomalies or local overheating in time, thereby avoiding discomfort or safety hazards caused by excessive temperature differences; at the same time, continuous data monitoring provides an important basis for the system's subsequent temperature guidance strategy, so that the temperature control strategy has a closed-loop feedback characteristic; this method not only improves the temperature control accuracy and response speed, but also actively adapts to the driver's adjustment of the grip position during driving; thus, the system ensures the driver's comfort while also enhancing safety and stability; this real-time monitoring and feedback mechanism embodies the advantages of adaptive and multi-level regulation of the intelligent temperature control system.

[0098] After completing the first temperature adjustment strategy, the temperature of each area on the steering wheel is monitored, and the guided temperature control strategy is selected for execution.

[0099] The first temperature adjustment strategy for other areas of the steering wheel except the currently used area includes:

[0100] The area on the steering wheel is divided into area No. 1 and area No. 2;

[0101] The heating of area 1 and area 2 on the steering wheel is controlled separately.

[0102] Reference Figure 1 , the dividing of the area on the steering wheel includes:

[0103] Obtain the center points of two areas in the currently used area respectively, connect them, and record the line as the dividing line;

[0104] Use a dividing line to divide the steering wheel into two areas, and record the area above the dividing line as the upper area, and record the area below the dividing line as the lower area;

[0105] Remove the part of the area that overlaps with the currently used area from the upper area, and record the remaining area as area No. 1;

[0106] In the lower area, the part of the area that overlaps with the current use area is removed, and the remaining area is recorded as area No. 2. Fine division of the steering wheel area is the key link to ensure the accuracy of temperature control; this process obtains the center points of the two areas in the current use area and connects them to form a dividing line, thereby dividing the steering wheel into an upper area and a lower area; in each area, the part that overlaps with the current use area is removed to form area No. 1 and area No. 2, so that the temperature control system can implement precise heating for each independent area; this area division method based on geometric centers and lines ensures the scientific nature and adaptability of steering wheel temperature control; it not only makes temperature control more detailed, but also ensures differentiated management of heating temperatures in different areas; at the same time, by clearly dividing the areas, the system can avoid temperature control overlaps and adjustment errors, thereby improving the balance of temperature distribution; this method also provides a clear physical boundary for subsequent temperature guidance strategies, making the entire temperature control process more efficient and intelligent.

[0107] The heating control of the first area and the second area on the steering wheel respectively includes:

[0108] Set the temperature percentage used to control the heating temperature of area 1 and area 2, and record it as the temperature difference ratio;

[0109] Calculate the product of the common temperature and the temperature difference ratio, and record the result as the temperature difference;

[0112] Control the heating temperature of area No. 1 to be equal to temperature No. 1;

[0113] The heating temperature of the No. 2 area is controlled to be equal to the No. 2 temperature. The first temperature control strategy is used to accurately control the temperature of the non-driver grip area on the steering wheel, and three different temperature distributions can be formed on the steering wheel, namely, the area with common temperature, higher than common temperature and lower than common temperature, so as to provide clear temperature indication for the subsequent driver to change the grip position; this design enables the system to detect the temperature level of the area entered by the driver in real time after the driver changes the grip position, and quickly determine whether the current grip area is higher or lower than the common temperature, thereby providing a basis for selecting and executing the No. 1 guided temperature control strategy or the No. 2 guided temperature control strategy; this multi-temperature distribution scheme not only realizes the hierarchical regulation of the overall temperature field of the steering wheel, but also ensures that the system can quickly respond and identify the temperature state of the new grip area when the driver adjusts the grip posture through temperature differentiation processing, so as to know whether the common temperature is high or low for the driver in the current environment, and then perform adaptive temperature adjustment and guidance, which helps to ensure the driver's driving comfort and improve driving safety at the same time.

[0114] After the first temperature adjustment strategy is completed, the temperature of each area on the steering wheel is monitored, and the guiding temperature control strategy is selected for execution, including:

[0115] Monitor the temperature of each area on the steering wheel to determine whether there is a transfer area;

[0116] If there is no transfer area, the heating temperature of each area on the current steering wheel remains unchanged;

[0117] When there is a transfer area, obtain the location of the transfer area;

[0118] If the transfer area is within area No. 1, the No. 1 guided temperature control strategy is executed;

[0119] If the transfer area is within the No. 2 area, the No. 2 guided temperature control strategy is executed;

[0120] If the transfer area is within area 1 and area 2 at the same time, the driver is prompted to manually adjust the heating temperature of the steering wheel.

[0121] The monitoring of the temperature of each area on the steering wheel to determine whether there is a transfer area includes:

[0122] When the temperature of two areas is monitored to rise, the two areas are marked as two marked areas;

[0123] Compare the two marked regions with the currently used region;

[0124] If the two marked areas overlap with the currently used area, it is determined that there is no transfer area;

[0125] If there is no overlap between the two marked areas and the currently used area, it is determined that there is a transfer area, and the two marked areas are used as two transfer areas.

[0126] If the transfer area is within area No. 1, the No. 1 guiding temperature control strategy is executed, including:

[0127] S1. Reference Figure 2 , respectively obtain the center points of the two transfer areas and record them as two transfer division points;

[0128] S2. Draw a straight line through the two transfer dividing points and record the straight line as the transfer dividing line;

[0130] S4, recording the area on the steering wheel below the transfer dividing line as the second dividing area;

[0131] S5, obtaining the temperature of the transfer area, and recording it as the transfer temperature;

[0132] S6, controlling the heating temperature of the first divided area to be less than or equal to half of the transfer temperature;

[0133] S7, controlling the heating temperature of the second divided area to be equal to the transfer temperature;

[0134] S8, monitoring the temperature of each area on the steering wheel, obtaining the area with increased temperature, and recording it as the adjustment area;

[0135] S9, comparing the adjustment area with the currently used area;

[0136] S10, if the adjustment area and the current use area overlap, control the heating temperature of the adjustment area on the steering wheel to be equal to the transfer temperature, use the transfer temperature as the common temperature, use the transfer area as the current use area, and execute the first temperature adjustment strategy;

[0137] S11. If the adjustment area does not overlap with the current use area, the original transfer area is deleted, the temperature of each area on the steering wheel is monitored, and the area with increased temperature is obtained and recorded as the transfer area;

[0138] Repeat steps S1-S11 until the adjustment area overlaps with the current use area, and the first guided temperature control strategy is completed. The No. 1 guided temperature control strategy executed when the transfer area is in the No. 1 area fully demonstrates the advantages of partitioned guided control; in this strategy, by obtaining the center point of the transfer area and constructing the transfer dividing line, the steering wheel is further subdivided into the No. 1 divided area and the No. 2 divided area, so as to achieve refined management of local temperature control; by controlling the heating temperature of the No. 1 divided area within a certain proportion of the transfer temperature, while the temperature of the No. 2 divided area is kept at the transfer temperature level, the contrast between hot and cold temperatures is obvious; this design enables the driver to perceive the temperature imbalance when holding the wheel, so as to spontaneously adjust the holding position to restore the comfortable state, thereby guiding the driver's hand holding position back to the commonly used position; at the same time, the strategy continuously compares the adjustment area with the current use area during the continuous monitoring of temperature changes, ensuring the closed-loop feedback and continuous iterative optimization of temperature control; partitioned guided control not only improves the temperature control response speed, but also ensures the driver's safety and comfort experience; the implementation of this strategy realizes dynamic temperature guidance and intelligent adjustment, thereby significantly improving the system's ability to adapt to temperature changes in the hand holding area.

[0139] If the transfer area is within the No. 2 area, the No. 2 guiding temperature control strategy is executed, including:

[0140] S12, respectively obtaining the center points of the two transfer areas and recording them as two transfer division points;

[0141] S13, draw a straight line through the two transfer division points, and record the straight line as the transfer division line;

[0142] S14, recording the area on the steering wheel above the transfer dividing line as a first dividing area;

[0143] S15, recording the area on the steering wheel below the transfer dividing line as the second dividing area;

[0144] S16, obtaining the temperature of the transfer area, and recording it as the transfer temperature;

[0145] S17, controlling the heating temperature of the first divided area to be equal to the transfer temperature;

[0146] S18, controlling the heating temperature of the second divided area to be greater than or equal to twice the transfer temperature;

[0147] S19, monitoring the temperature of each area on the steering wheel, obtaining an area with increased temperature, and recording it as an adjustment area;

[0148] S20, comparing the adjustment area with the currently used area;

[0149] S21, if the adjustment area and the current use area overlap, control the heating temperature of the adjustment area on the steering wheel to be equal to the transfer temperature, use the transfer temperature as the common temperature, use the transfer area as the current use area, and execute the first temperature adjustment strategy;

[0150] S22, if the adjustment area does not overlap with the current use area, the original transfer area is deleted, the temperature of each area on the steering wheel is monitored, and the area with increased temperature is obtained and recorded as the transfer area;

[0151] Repeat steps S12-S22 until the adjustment area overlaps with the current use area, and the second guided temperature control strategy is completed. The second guided temperature control strategy executed when the transfer area is in the second area reflects a more obvious advantage in temperature gradient control; this strategy divides the steering wheel into the first and second divided areas by obtaining the center points of the transfer areas to form a transfer dividing line, and sets different heating temperatures for them respectively; in this process, the temperature of the first divided area is set to the transfer temperature, while the temperature of the second divided area is controlled at a higher multiple of the transfer temperature, thereby forming a significant difference in temperature; this obvious temperature difference design provides the driver with an intuitive temperature guidance signal, prompting him to automatically adjust the grip position to achieve the most suitable temperature control state, thereby guiding the driver's hand holding the steering wheel back to the commonly used position; at the same time, the system can accurately compare the adjustment area with the current use area in the process of continuously monitoring the temperature changes in each area, thereby ensuring the accuracy and continuity of the temperature control adjustment; this partitioned temperature gradient control method enables the temperature control system to meet the comfort requirements while also improving the overall operational safety and intelligent response level.
