[0043] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0044] The present application embodiment provides a vehicle seat heating control method, which is executed by a vehicle seat heating system. Please refer to Figure 1, which shows a logical structural block diagram of the vehicle seat heating system provided in an embodiment of the present application. The vehicle seat heating system includes: a seat control module 101, a thermistor 102 (Negative Temperature Coefficient, NTC), and a heating element 103. The seat control module 101 can be a seat controller (Seat Control Unit, SCU), for example, a seat heating controller. The resistance of the NTC thermistor 102 changes with temperature. The higher the temperature, the smaller the resistance of the NTC thermistor 102. The heating element 103 can be a heating wire. After the voltage is configured for the heating element 103, the temperature of the heating element 103 will increase, thereby heating the seat. The design of the heating element 103 needs to take into account both heating efficiency and energy consumption, ensuring rapid heating while avoiding energy waste.

[0045] In the embodiment of the present application, the vehicle seat heating system further includes a user input device 104 and a gateway (Central Gateway, CGW) 105 .

[0046] The user input device 104 is communicatively connected to the gateway 105, which is in turn communicatively connected to the seat control module 101. This communication connection may involve direct communication via CAN, LIN, or Ethernet, or indirect communication via a gateway router. The user input device 104 may be a mobile terminal communicatively connected to an onboard terminal, or it may be an onboard terminal. For example, the user input device 104 may be an onboard host computer. The user may perform user operations based on the user input device 104 to set the heating level.

[0047] The seat control module 101 and NTC thermistor 102 are connected via a wiring harness. NTC thermistor 102 is mounted on the seat and serves as a temperature sensing element to determine the seat temperature. As the seat temperature changes, the temperature of NTC thermistor 102 also changes, and consequently, the resistance of NTC thermistor 102 also changes. Specifically, the higher the temperature of NTC thermistor 102, the lower its resistance. After obtaining the resistance of NTC thermistor 102, the seat control module 101 determines the seat temperature based on a mapping between the resistance and temperature of NTC thermistor 102 and the resistance of NTC thermistor 102.

[0048] The seat control module 101 and the heating element 103 are connected via a wiring harness. The heating element 103 is mounted on the seat, specifically inside the seat. The seat control module 101 sets the voltage applied to the heating element 103 based on the initial temperature and the heating level indicated by the seat heating command. The heating element 103 then heats the seat, increasing the seat temperature. The NTC thermistor 102 and the heating element 103 are also connected via a wiring harness.

[0049] In this embodiment of the present application, when the user activates the seat heating function, the seat control module 101 automatically implements different heating strategies based on the ambient temperature (the initial resistance of the NTC thermistor 102). Based on the different heating strategies, the voltage applied to the heating element 103 is configured. The heating element 103 operates to heat the seat, raising the seat temperature to the set value. When the seat temperature changes, the resistance of the NTC thermistor 102 also changes. The seat control module 101 then adjusts the heating strategy based on the resistance of the NTC thermistor 102, ensuring that the seat reaches the desired temperature in the shortest possible time.

[0050] Based on the above Figure 1 The vehicle seat heating system implementation environment shown in the figure, the embodiment of the present application provides a vehicle seat heating method, such as Figure 2 As shown, the method is applied to a vehicle seat heating system, and the method includes steps 201 to 203.

[0051] Step 201: In response to receiving a seat heating instruction, obtain an initial temperature of the seat.

[0052] In the present embodiment, the seat temperature refers to the seat's internal temperature. It will be appreciated that since the thermistor is enclosed within the seat body, the seat temperature determined based on the thermistor's resistance can be considered the seat's internal temperature, while the seat's surface temperature increases as the seat's internal temperature increases. Therefore, the seat's surface temperature can be controlled by controlling the seat's internal temperature.

[0053] In an embodiment of the present application, a user sets a heating level through a user input device. The user input device generates a seat heating command based on the user's operation and forwards the seat heating command to a seat heating controller via a gateway. The seat heating command includes the heating level. Based on the seat heating command, the seat heating controller obtains the resistance of a thermistor connected to the seat heating controller, i.e., the initial resistance of the thermistor upon receiving the seat heating command. Based on the initial resistance value and the relationship between the thermistor resistance and temperature, the seat heating controller then obtains an initial temperature corresponding to the initial resistance value, which is recorded as the initial temperature of the seat.

[0054] In another embodiment of the present application, the seat temperature is the seat surface temperature. Specifically, after receiving the seat heating instruction, the seat heating controller can obtain the seat surface temperature from the temperature sensor. Specifically, the seat temperature is measured by the temperature sensor. When the temperature sensor obtains the seat surface temperature, it will be sent to the seat heating controller, so that the seat heating controller obtains the seat surface temperature.

[0055] Step 202 : When the initial temperature is not lower than the initial temperature threshold, in response to the seat heating instruction, heat the seat in a normal heating mode.

[0056] It is understood that before the seat is heated, it is in an unheated state, and the seat temperature is primarily affected by the ambient temperature. The lower the ambient temperature, the lower the initial temperature, and conversely, the higher the ambient temperature, the higher the initial temperature. Therefore, the initial temperature can represent the ambient temperature. The ambient temperature can be the temperature inside the vehicle or the temperature outside the vehicle. When representing the ambient temperature by the initial temperature, it can be assumed that the initial temperature is equal to the ambient temperature, or that the temperature difference between the initial temperature and the ambient temperature is within a preset temperature difference range. Furthermore, after obtaining the initial seat temperature, by determining the initial seat temperature, the ambient temperature of the seat can be determined, allowing different heating strategies to be implemented under different ambient temperatures.

[0057] In the embodiment of the present application, the initial temperature threshold can be set as needed. The initial temperature threshold can be a specific temperature value. For example, the initial temperature threshold can be 15°C, 20°C, or 25°C.

[0058] In the embodiment of the present application, when the initial temperature is not lower than the initial temperature threshold, it means that the ambient temperature is not very low. Therefore, based on the heating gear indicated by the seat heating instruction, the seat is heated through the normal heating mode, which can not only meet the user's seat heating needs, but also reduce energy consumption compared to the rapid heating mode.

[0059] Step 203 : When the initial seat temperature is lower than the initial temperature threshold, in response to the seat heating instruction, the seat is heated in a rapid heating mode, wherein the heating power corresponding to the rapid heating mode is greater than the heating power corresponding to the normal heating mode.

[0060] In this embodiment of the present application, for the same heating level, the heating power corresponding to the rapid heating mode is greater than the heating power corresponding to the normal heating mode, where the heating power is the average heating power. That is, for the same heating level and for the same time, the average heating power corresponding to the rapid heating mode is greater than the average heating power corresponding to the normal heating mode. Therefore, for the same heating level and for the same time, the seat temperature rises faster in the rapid heating mode than in the normal heating mode.

[0061] In the embodiment of the present application, the initial temperature can represent the ambient temperature. Therefore, if the initial temperature is lower than the initial temperature threshold, it indicates that the ambient temperature is relatively low. To ensure user comfort, the seat temperature needs to be quickly increased under low ambient temperature conditions. In this case, the seat temperature is quickly increased based on a higher target temperature in the rapid heating mode. If the initial temperature is not lower than the initial temperature threshold, it indicates that the ambient temperature is relatively high. In this case, the seat is heated in the normal heating mode at a target temperature lower than that of the rapid heating mode, without requiring a higher heating efficiency to quickly increase the seat temperature. This avoids energy waste and prevents user discomfort caused by higher seat surface temperatures due to higher heating efficiency.

[0062] Figure 3 This is another flow chart of vehicle seat heating provided according to an embodiment of the present application. Figure 3 As shown, the vehicle seat heating includes the following steps:

[0063] Step 301: In response to receiving a seat heating instruction, obtain an initial temperature of the seat.

[0064] Step 301 may refer to the above-mentioned step 101 and will not be described in detail here.

[0065] Step 302 : When the initial seat temperature is lower than the initial temperature threshold, the seat temperature target temperature is set to a first target temperature based on the heating level indicated by the seat heating instruction.

[0066] In the embodiment of the present application, the target temperature is the temperature that the seat is expected to reach when the seat is heated. During the seat heating process, the target temperature may change. For example, at the beginning of heating, the seat temperature may be expected to increase rapidly, but after a period of heating, the seat temperature may be expected to decrease to avoid overheating. Therefore, the target temperature may be higher at the beginning of heating and lower after a period of heating.

[0067] In this embodiment, if the seat temperature is greater than the target temperature, the heating element power is reduced or stopped to lower the seat temperature. If the seat temperature is less than the target temperature, the heating element power is increased to raise the seat temperature. If the seat temperature is at the target temperature, the heating element power is periodically activated to maintain the seat temperature at the target temperature. In other words, in this embodiment, the seat temperature is directed toward the target temperature, thereby facilitating seat temperature control based on the target temperature.

[0068] When a user performs a user operation using a user input device, the user can set a heating level at which heating is to be initiated. The seat heating controller sets a target temperature, i.e., a first target temperature, based on the heating level indicated by the seat heating instruction. Specifically, the first target temperature corresponding to the heating level indicated by the seat heating instruction can be determined based on a correspondence between the heating level and the target temperature.

[0069] Step 303: Heat the seat so that the seat temperature rises from the initial temperature to the first target temperature, and record the heating time consumed in the heating stage.

[0070] By configuring the voltage applied to the heating element, the heating element is heated to heat the seat, so that the heating process of the seat enters the heating stage and starts recording the heating time consumed in the heating stage.

[0071] Step 304: Determine the temperature maintenance duration of the temperature maintenance phase based on the temperature rise duration, and maintain the seat temperature at the first target temperature during the temperature maintenance phase.

[0072] In the embodiment of the present application, after the seat temperature reaches the first target temperature, the heating process of the seat enters the temperature maintenance stage, and the seat temperature will be maintained at the first target temperature during the temperature maintenance stage.

[0073] In the embodiment of the present application, the temperature maintenance time is determined based on the temperature rise time, wherein the temperature rise time is positively correlated with the temperature maintenance time. For example, the temperature maintenance time is in positive proportion to the temperature rise time.

[0074] In the embodiment of the present application, the first coefficient corresponding to the heating gear indicated by the user is determined based on the correspondence between the heating gear and the first coefficient, and the temperature maintenance time is determined by the heating time and the first coefficient. The coefficients corresponding to different heating gears are different or the same. For example, when the heating gear indicated by the user is gear 3, the first coefficient is determined to be 0.8 according to the heating gear and coefficient table, then the temperature maintenance time = 0.8 × heating time. For another example, when the heating gear indicated by the user is gear 2, the first coefficient is determined to be 0.33 according to the heating gear and coefficient table, then the temperature maintenance time = 0.33 × heating time. For another example, when the heating gear indicated by the user is gear 1, the first coefficient is determined to be 1 according to the heating gear and coefficient table, then the temperature maintenance time = 1 × heating time.

[0075] In another embodiment of the present application, the temperature maintenance time and the temperature rising time are in a logarithmic or exponential relationship.

[0076] In the embodiment of the present application, the longer the heating time, the lower the ambient temperature, and the shorter the heating time, the higher the ambient temperature. Since the heating time is positively correlated with the temperature maintenance time, the temperature maintenance time in the temperature maintenance stage can vary according to the ambient temperature. That is, in the embodiment of the present application, the temperature maintenance time in the temperature maintenance stage will be longer than that in the case of lower ambient temperature. Since the heating time is positively correlated with the temperature maintenance time, the temperature maintenance time corresponding to the ambient temperature can be flexibly adapted to avoid mismatch between the ambient temperature and the temperature maintenance time, which may cause the seat temperature to drop or the seat temperature to be too high, causing discomfort to the user.

[0077] In the embodiment of the present application, before determining the temperature maintenance duration of the temperature maintenance stage based on the temperature rise duration, the method further includes: step 3041 and step 3042.

[0078] Step 3041: If the heating time is greater than the second time threshold, switch from the rapid heating mode to the normal heating mode, and heat the seat based on the normal heating mode.

[0079] Step 3042: If the heating time is not greater than the second time threshold, then executing the step of determining the temperature maintenance time of the temperature maintenance stage based on the heating time.

[0080] After the heating element heats the seat, the seat temperature may or may not rise from the initial temperature to the first target temperature due to the influence of the ambient temperature. Therefore, in this embodiment of the application, the time it takes for the seat temperature to rise from the initial temperature, i.e., the heating time of the heating phase, is also recorded. This heating time is then used to determine whether the seat temperature has risen to the first target temperature within a second time threshold.

[0081] In an embodiment of the present application, for the same heating time and the same heating gear, the minimum value of the seat target temperature in the rapid heating mode is greater than or equal to the minimum value of the seat target temperature in the normal heating mode, and for the same heating gear, the maximum value of the seat target temperature in the rapid heating mode is greater than the maximum value of the seat target temperature in the normal heating mode. After switching from the rapid heating mode to the normal heating mode, the target temperature of the seat will also be adjusted accordingly. For example, after switching from the rapid heating mode to the normal heating mode, the target temperature will be lowered or remain unchanged.

[0082] In another embodiment of the present application, before determining the temperature maintenance duration of the temperature maintenance stage based on the temperature rise duration, the method further includes: step 3043 and step 3046.

[0083] Step 3043: If the heating time is greater than the second time threshold, determine whether the heating level indicated by the seat heating instruction is the maximum heating level.

[0084] Step 3044: When the heating gear indicated by the seat heating instruction is the maximum heating gear, the rapid heating mode is switched to the normal heating mode, and the seat is heated based on the normal heating mode.

[0085] Step 3045: When the heating level indicated by the seat heating instruction is less than the maximum heating level, the rapid heating mode is switched to the normal heating mode, and the heating level is increased, and the seat is heated based on the increased heating level.

[0086] Step 3046: If the heating time is not greater than the second time threshold, then the step of determining the temperature maintenance time of the temperature maintenance stage based on the heating time is executed.

[0087] In the embodiment of the present application, if the heating time is too long, it indicates that the environment is too cold. Considering that the heating element operates at a high power for a long time in the rapid heating mode, it is determined whether the heating level indicated by the seat heating instruction is the maximum heating level. If it is the maximum heating level, the risk factor of the heating element increases. Therefore, the seat is switched from rapid heating mode to normal heating mode to lower the target temperature of the seat. The seat is then heated based on the normal heating mode, thereby improving safety. If the heating level indicated by the seat heating instruction is less than the maximum heating level, the heating element is sufficiently safe. To quickly increase the temperature, the rapid heating mode is switched to normal heating mode, and the heating level is increased. In normal heating mode, the seat is heated based on the increased heating level.

[0088] Step 305: After the temperature maintenance stage, if the heating gear is greater than the lowest heating gear, after the temperature maintenance stage, the heating gear is reduced, and the seat is heated based on the reduced heating gear.

[0089] In an embodiment of the present application, after the temperature maintenance stage, the seat temperature has reached the first target temperature and maintained the first target temperature for a certain period of time. The seat surface temperature is sufficient to meet the user's needs after changing with the seat temperature. If the seat temperature continues to maintain the first target temperature, the seat surface temperature will be too high. Therefore, after the temperature maintenance stage, if the heating gear is greater than the lowest heating gear, the heating gear is lowered, and the seat is heated based on the lowered heating gear.

[0090] Step 306: If the heating gear is the lowest heating gear, set the target temperature to a second target temperature so that the seat temperature is maintained at the second target temperature, wherein the second target temperature is lower than the first target temperature.

[0091] If the heating level is at the lowest setting, the heating level cannot be lowered. To prevent the seat from overheating and causing the seat surface temperature to overheat, the target temperature is adjusted to a second target temperature to lower the seat temperature. Specifically, the seat temperature can be lowered and maintained at the target temperature by reducing the power of the heating element or stopping the heating element. Specifically, the second target temperature corresponding to the heating level indicated by the seat heating instruction can be determined based on the corresponding relationship between the heating level and the target temperature.

[0092] In some embodiments, after the temperature maintenance stage, if the heating level is greater than the lowest heating level, the heating level is lowered, including: step 3051 and step 3052.

[0093] Step 3051: Determine the sum of the heating time and the temperature maintenance time to obtain a first time.

[0094] Step 3052: Based on the first duration, reduce the heating level.

[0095] A longer heating time indicates a lower ambient temperature, and the heating time is positively correlated with the temperature maintenance time. The first time is the sum of the heating time and the temperature maintenance time. Therefore, different first time periods correspond to different ambient temperatures. In this embodiment of the present application, the heating level is lowered based on the first time period, corresponding to different ambient temperatures. The first time period is used to determine the timing of lowering the heating level at different ambient temperatures, thereby improving energy efficiency.

[0096] In some embodiments, lowering the heating level based on the first duration includes: step 401 - step 402 .

[0097] Step 401: When the first duration is not greater than the first duration threshold, after the temperature maintenance phase, the target temperature is set to a third target temperature, wherein the third target temperature is lower than the first target temperature.

[0098] In the embodiment of the present application, different heating gears have corresponding target temperatures. Under the same heating mode, the target temperature corresponding to a higher heating gear is higher than the target temperature corresponding to a lower heating gear. In the embodiment of the present application, if the first duration is not greater than the first duration threshold, it indicates that the ambient temperature is not very cold. To avoid energy waste, after the temperature maintenance phase, the target temperature is lowered so that the seat temperature approaches the target temperature, thereby avoiding energy waste caused by high-temperature heating of the seat before downshifting.

[0099] In the embodiment of the present application, when determining the target temperature corresponding to the heating gear based on the correspondence between the heating gear and the target temperature, the target temperature corresponding to each heating gear in different heating stages can also be determined based on the correspondence between the target temperature and the heating stage, where the heating stage includes a temperature rise stage and a temperature maintenance stage. Therefore, based on the correspondence between the heating gear and the target temperature and the correspondence between the target temperature and the heating stage, a third target temperature corresponding to the heating gear after the temperature maintenance stage and / or a first target temperature corresponding to the heating gear during the temperature rise stage can be determined.

[0100] Step 402: When the downshift time point is reached, reduce the heating gear, wherein the downshift time point is determined according to the heating start time point and the first duration threshold.

[0101] In an embodiment of the present application, when the seat starts to heat, the heating start time point will be recorded. The heating start time point is also the start time of the heating phase. Then, the time point for lowering the heating gear is determined by the heating start time point and the first duration threshold to obtain the downshifting time point.

[0102] In some embodiments, the first duration threshold can be determined based on the ambient temperature. Thus, if the first duration is no greater than the first duration threshold, the time it takes for the seat temperature to decrease from the first target temperature to the third target temperature can vary with changes in the ambient temperature. The ambient temperature is the initial temperature, and the time it takes for the seat temperature to decrease from the first target temperature to the third target temperature is negatively correlated with the ambient temperature. That is, for the same heating level, the lower the ambient temperature, the longer it takes for the seat temperature to decrease from the first target temperature to the third target temperature, and the higher the ambient temperature, the shorter it takes for the seat temperature to decrease from the first target temperature to the third target temperature. Specifically, the first duration threshold corresponding to the current ambient temperature can be determined by setting a corresponding relationship between the first duration threshold and the ambient temperature.

[0103] In some embodiments, the first duration threshold is determined based on the heating level indicated by the user. Thus, if the first duration is no greater than the first duration threshold, the time it takes for the seat temperature to decrease from the first target temperature to the third target temperature can vary with the user-indicated heating level. For example, if the user-indicated heating level is level 3, the first duration threshold is 80%; if the user-indicated heating level is level 2, the first duration threshold is 33%; and if the user-indicated heating level is level 1, the first duration threshold is 100%.

[0104] In some embodiments, specifically, the correspondence between the ambient temperature and / or the heating level indicated by the user and the first duration threshold can be set, so that the first duration threshold corresponding to the current ambient temperature and / or the heating level indicated by the user can be determined based on the ambient temperature and / or the heating level indicated by the user.

[0105] In some embodiments, based on the first duration, lowering the heating level includes: step 403 .

[0106] Step 403: When the first duration is greater than the first duration threshold, after the temperature maintenance stage, reduce the heating gear.

[0107] In the embodiment of the present application, when the first time length is greater than the first time length threshold, it means that the ambient temperature is very cold, but because the first time length is long, the seat has been heated at a higher temperature for a sufficiently long time, and the seat surface temperature under the influence of the seat temperature is sufficient to meet the user's needs. In order to avoid energy waste, when the first time length is greater than the first time length threshold, the heating gear is directly lowered after the temperature maintenance stage.

[0108] In the process of executing the rapid heating mode, the heating time of the heating stage will be affected by the ambient temperature. The present application utilizes the rule that the heating time of the heating stage will be affected by the ambient temperature to make the temperature maintenance time of the temperature maintenance stage positively correlated with the heating time. The first coefficient of the temperature maintenance time and the heating time of the present application changes with the heating gear input by the user, so that the temperature maintenance time can be dynamically set according to the ambient temperature and / or the heating gear input by the user. At the same time, the first time threshold in the present application also changes with the change of the ambient temperature and / or the heating gear input by the user. Therefore, the first time threshold can be adjusted based on the ambient temperature and / or the heating gear input by the user to make the timing of downshifting or lowering the target temperature more consistent with the ambient temperature and / or the heating gear input by the user. The present application reasonably adjusts the duration and target temperature of the heating stage and the maintenance stage according to the external temperature and the heating gear selected by the user, so that the final downshift to energy-saving temperature maintenance strategy is reasonably arranged, thereby improving driving comfort and optimizing energy efficiency.

[0109] Preferably, heating the seat based on the lowered heating gear includes: steps 501 to 503.

[0110] Step 501: When the lowered heating level is greater than the lowest heating level, heat the seat for a second time period based on the lowered heating level.

[0111] Step 502: Lower the heating level again after the second time period, and repeat the step of heating the seat for a second time period based on the lowered heating level when the lowered heating level is greater than the lowest heating level, until the heating level reaches the lowest heating level.

[0112] Step 503: When the lowered heating gear is the lowest heating gear, heat the seat at the lowest heating gear.

[0113] In an embodiment of the present application, after the heating gear is lowered, it will be determined whether the lowered heating gear is greater than the lowest heating gear. If the lowered heating gear is the lowest heating gear, the seat will be heated at the lowest heating gear. If the lowered heating gear is greater than the lowest heating gear, the seat will be heated for a second time period based on the lowered heating gear. After the second time period, the heating gear will be lowered again, and it will be determined again whether the lowered heating gear is greater than the lowest heating gear.

[0114] In the embodiment of the present application, when the initial temperature is not lower than the initial temperature threshold, the seat is heated in a normal heating mode in response to a seat heating instruction, including: steps 2021 and 2022.

[0115] Step 2021: When the initial temperature of the seat is not lower than the initial temperature threshold, the seat is heated for a third time period based on the heating level indicated by the seat heating instruction.

[0116] Because the initial seat temperature is not lower than the initial temperature threshold, the initial temperature is relatively high. Since the initial temperature represents the ambient temperature, a high initial temperature indicates a high ambient temperature. When the ambient temperature is relatively high, the seat temperature reaches the target temperature and maintains the target temperature for a period of time based on the third heating time indicated by the user.

[0117] Step 2022: If the heating level is greater than the lowest heating level, reduce the heating level, and heat the seat based on the reduced heating level.

[0118] The seat heating based on the lowered heating level can be performed with reference to steps 501 to 503 above, which will not be described in detail here. That is, whether the seat is heated in the rapid heating mode or the normal heating mode, the present application will perform steps 501 to 503 after heating the seat based on the user-indicated heating level and lowering the heating level to gradually lower the heating level, thereby fully utilizing the residual heat of the seat and avoiding energy waste.

[0119] After heating the seat for the third period of time, if the heating level is greater than the lowest heating level, the heating level is lowered, and the seat is heated based on the lowered heating level. This can fully utilize the residual temperature of the seat to increase the surface temperature of the seat and avoid excessive energy consumption, and can also avoid discomfort to the user caused by the rapid drop in seat temperature.
