[0038] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 this application.

[0039] 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.

[0040] In a first aspect, an embodiment of the present application provides a steering wheel heating control method.

[0041] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of an embodiment of the steering wheel heating control method of the present application. Figure 1 As shown, the steering wheel heating control method includes:

[0042] Step S10: estimating the target vehicle interior temperature increase required for the current vehicle interior temperature to rise to a preset target vehicle interior temperature within the scheduled vehicle use time.

[0043] For example, in an embodiment of the present application, user appointment information can be received through the on-board communication module, the on-board communication module wakes up the body controller and the vehicle controller, and temperature sensors can be installed on the steering wheel and inside the vehicle to monitor the steering wheel surface temperature and the temperature inside the vehicle in real time. The transmission frequency of the sensor can be set to once per minute, and the central control system can receive temperature data sent by the temperature sensor.

[0044] Specifically, users can select the time to reserve a car through a mobile phone APP or other device terminal, where the reserved car time M Y and the preset target interior temperature T CNYThe specific value of can be determined according to the actual needs of the user and is not limited here. For example, the reserved car time can be 10 minutes. It is understandable that drivers often want the temperature in the car to reach a comfortable level before they get in the car, so they usually choose to start the air conditioning and heating in advance during the reserved car time. The air conditioning and heating will affect the steering wheel temperature. Therefore, when controlling the steering wheel heating, it is necessary to consider the impact of the air conditioning and heating on the steering wheel heating control. Specifically, this can be done by estimating the current temperature T in the car due to the air conditioning and heating. CNN The temperature inside the vehicle rises to the target temperature T within the scheduled time. CNY The required target vehicle interior temperature increase is used to more accurately control the heating of the steering wheel.

[0045] It should be noted that the embodiment of the present application can control the current temperature in the car to rise to a preset target car temperature within the scheduled car use time while controlling the heating of the steering wheel, so as to achieve preheating of the car temperature before using the car, thereby ensuring that the car interior environment has reached a comfortable temperature when the owner enters the vehicle, allowing the owner to directly enjoy the warm car interior environment after the scheduled car use time, without having to wait for the temperature to rise after starting the car, thereby improving the driving experience.

[0046] Step S20: Determine a target steering wheel temperature rise based on the target vehicle interior temperature rise and a preset mapping relationship between the vehicle interior temperature rise and the steering wheel temperature rise.

[0047] Exemplarily, in an embodiment of the present application, a mapping relationship between the temperature rise inside the vehicle and the temperature rise of the steering wheel when the air conditioning heating is turned on can be established through multiple preliminary experiments. For example, a 5°C increase in the temperature inside the vehicle can cause the steering wheel temperature to rise by 2°C. Therefore, the target temperature rise inside the vehicle and the mapping relationship are known, and the target steering wheel temperature rise can be calculated. The calculation of the target steering wheel temperature rise takes into account the impact of air conditioning heating on the increase in steering wheel temperature, thereby avoiding excessive heating or energy waste.

[0048] Step S30: Determine a second steering wheel temperature based on the first steering wheel temperature and the target steering wheel temperature rise, where the first steering wheel temperature is the current temperature of the steering wheel before the current temperature inside the vehicle rises to the target vehicle temperature.

[0049] For example, in the embodiment of the present application, the current temperature of the steering wheel corresponding to the current temperature in the vehicle before it rises to the target vehicle temperature (i.e., the first steering wheel temperature) can be obtained by using the vehicle temperature sensor. The target steering wheel temperature and the first steering wheel temperature can be added to obtain the second steering wheel temperature (i.e., the current steering wheel temperature corresponding to the time when the current temperature in the vehicle rises to the target vehicle temperature). SWN ), ensuring that the steering wheel gradually reaches a comfortable level as the temperature inside the car rises, improving the driving experience.

[0050] Step S40: Based on the second steering wheel temperature, the steering wheel is controlled to heat to a preset target steering wheel temperature within the scheduled vehicle use time.

[0051] For example, in the embodiment of the present application, the preset target steering wheel temperature T SWY The specific value of can be determined based on actual needs and is not limited here. During the scheduled use time, the steering wheel is heated to the preset target steering wheel temperature based on the difference between the second steering wheel temperature and the target steering wheel temperature. The preheating function heats the steering wheel before use, saving time while driving and ensuring the steering wheel is at an appropriate temperature before use, helping to maintain hand comfort and reduce driving discomfort caused by cold weather. By properly controlling the heating time and intensity, the energy efficiency of the heating system is improved and excessive energy consumption is avoided.

[0052] The following example describes the heating control strategy for achieving target interior and steering wheel temperatures:

[0053] Assume that the reserved car use time is 10 minutes, and the steering wheel heating and air conditioning are turned on at the same time, and the interior temperature and steering wheel temperature are controlled to reach the corresponding target temperature within 10 minutes; Among them, when performing steering wheel heating, it is necessary to first estimate the target interior temperature increase required when the interior temperature reaches the target interior temperature, and then control the steering wheel heating to the target steering wheel temperature T according to the target interior temperature increase. SWY .

[0054] It is understandable that the vehicle system can traverse all heating control strategy solutions that meet the target air-conditioning temperature and target steering wheel temperature requirements, and select the strategy with the lowest energy consumption for heating.

[0055] This application estimates the target vehicle interior temperature rise required for the current vehicle interior temperature to rise to the preset target vehicle interior temperature within the scheduled vehicle use time; then determines the target steering wheel temperature rise based on the target vehicle interior temperature rise and the mapping relationship between the vehicle interior temperature rise and the steering wheel temperature rise, thereby estimating the heating demand of the steering wheel; obtains the steering wheel temperature when the current vehicle interior temperature has not yet reached the target vehicle interior temperature and determines a second steering wheel temperature in combination with the target steering wheel temperature rise; controls the steering wheel heating to the preset target steering wheel temperature within the scheduled time based on the second steering wheel temperature, thereby ensuring that the steering wheel is already within a comfortable temperature range when the user enters the vehicle. Through the above-mentioned automatic adjustment and heating control, this application allows users to enjoy a comfortable driving environment after the scheduled vehicle use time, saves time waiting for the vehicle interior temperature and steering wheel temperature to adjust, and thus improves the overall riding experience.

[0056] Furthermore, in one embodiment, referring to Figure 2As shown, controlling the steering wheel to heat to a preset target steering wheel temperature within the scheduled vehicle use time based on the second steering wheel temperature includes:

[0057] Step S401: determining the steering wheel temperature to be heated based on the target steering wheel temperature and the second steering wheel temperature;

[0058] Step S402: determining a target steering wheel heating gear according to the steering wheel temperature and the amount of heating to be performed;

[0059] Step S403: Based on the target steering wheel heating gear, the steering wheel is controlled to heat to the target steering wheel temperature within the scheduled vehicle use time.

[0060] Exemplarily, in an embodiment of the present application, the target steering wheel temperature and the second steering wheel temperature are subtracted to obtain the steering wheel temperature to be heated (i.e., the temperature of the steering wheel needs to be increased); the target steering wheel heating gear is determined based on the calculated steering wheel temperature to be heated, wherein different heating gears correspond to different heating powers or temperature rise rates, and the heating intensity can be adjusted by selecting different gears; the working state of the steering wheel heating system is controlled according to the target steering wheel heating gear to ensure that the temperature gradually increases during the heating process and reaches the target steering wheel temperature.

[0061] As you can see, precise control of steering wheel heating ensures the desired steering wheel temperature during the scheduled use time, reducing waiting time and improving the driving experience. Furthermore, proper steering wheel temperature helps keep the driver's hands comfortable, reducing discomfort or distraction caused by an overheated or cold steering wheel, thereby improving driving safety.

[0062] Furthermore, in one embodiment, after the step of controlling the steering wheel to heat to a target steering wheel temperature, the method further includes:

[0063] When it is detected that the driver's seat pressure signal is greater than a preset pressure signal threshold, the steering wheel heating is turned off.

[0064] For example, in the embodiment of the present application, the specific value of the preset pressure signal threshold can be determined based on actual needs and is not limited herein. The driver's seat pressure signal can be obtained via the driver's seat sensor, and the relationship between the driver's seat pressure signal and the pressure signal threshold can be determined. When the driver's seat pressure signal is detected to be greater than the pressure signal threshold, indicating that the driver is in his seat, the steering wheel heating is turned off to avoid steering wheel overheating and unnecessary energy consumption. In other words, when the driver's seat pressure signal is detected to be less than or equal to the pressure signal threshold, indicating that the driver is not in his seat, the steering wheel heating is maintained.

[0065] In a second aspect, an embodiment of the present application provides a steering wheel heating control method. In one embodiment, the steering wheel heating control method includes:

[0066] Step P10: During the scheduled vehicle usage time, the current temperature inside the vehicle is raised to the preset target vehicle temperature, and then the current temperature of the steering wheel is output. The steering wheel is then heated to the preset target steering wheel temperature according to the current temperature of the steering wheel.

[0067] For example, in an embodiment of the present application, during the scheduled vehicle use time, the current vehicle interior temperature can be raised to the target vehicle interior temperature by turning on the air conditioning and heating. Simultaneously, the steering wheel temperature sensor can be used to obtain the current steering wheel temperature corresponding to the time the current vehicle interior temperature rises to the target vehicle interior temperature. Then, based on the current steering wheel temperature, the steering wheel heating is turned on to heat the steering wheel to the target steering wheel temperature. This ensures that both the vehicle interior and the steering wheel temperatures reach comfortable preset target values ​​when the user enters the vehicle, enhancing the driving experience. By adjusting the vehicle interior temperature first and then controlling the steering wheel temperature, the present application improves overall heating efficiency and avoids energy waste.

[0068] Furthermore, in one embodiment, raising the current temperature inside the vehicle to a preset target temperature inside the vehicle includes:

[0069] Determining a target air conditioning heating gear according to the current temperature in the vehicle and the target vehicle temperature;

[0070] The current temperature in the vehicle is controlled to rise to the target vehicle temperature according to the target air-conditioning heating gear.

[0071] For example, in this embodiment of the present application, the current vehicle interior temperature can be obtained through an in-vehicle temperature sensor. The target air conditioning heating level is determined based on the difference between the current vehicle interior temperature and the target vehicle interior temperature. This ensures that the heating power can effectively raise the vehicle interior temperature to the target temperature, ensuring that the vehicle interior temperature reaches a comfortable temperature within the user's scheduled use time, thereby improving the riding experience. By properly adjusting the air conditioning heating level, energy can be efficiently utilized and unnecessary energy waste can be prevented.

[0072] Furthermore, in one embodiment, controlling the steering wheel to be heated to a preset target steering wheel temperature according to the current temperature of the steering wheel includes:

[0073] determining a target steering wheel heating gear according to the current temperature of the steering wheel and the target steering wheel temperature;

[0074] The steering wheel is controlled to be heated to a target steering wheel temperature based on the target steering wheel heating gear.

[0075] For example, in an embodiment of the present application, the current temperature of the steering wheel can be obtained through a steering wheel temperature sensor, and then the target steering wheel heating gear can be determined by calculating the difference between the current temperature of the steering wheel and the target steering wheel temperature; the working state of the steering wheel heating system is controlled according to the target steering wheel heating gear to ensure that the temperature gradually increases during the heating process and reaches the target steering wheel temperature, wherein different heating gears correspond to different heating powers or temperature rise rates, and the heating intensity can be adjusted through different gears.

[0076] As you can see, precise control of steering wheel heating ensures the desired steering wheel temperature during the scheduled use time, reducing waiting time and improving the driving experience. Furthermore, proper steering wheel temperature helps keep the driver's hands comfortable, reducing discomfort or distraction caused by an overheated or cold steering wheel, thereby improving driving safety.

[0077] Furthermore, in one embodiment, after the step of controlling the steering wheel to heat to a target steering wheel temperature, the method further includes:

[0078] When it is detected that the driver's seat pressure signal is greater than a preset pressure signal threshold, the steering wheel heating is turned off.

[0079] For example, in the embodiment of the present application, the specific value of the preset pressure signal threshold can be determined based on actual needs and is not limited herein. The driver's seat pressure signal can be obtained via the driver's seat sensor, and the relationship between the driver's seat pressure signal and the pressure signal threshold can be determined. When the driver's seat pressure signal is detected to be greater than the pressure signal threshold, indicating that the driver is in his seat, the steering wheel heating is turned off to avoid steering wheel overheating and unnecessary energy consumption. In other words, when the driver's seat pressure signal is detected to be less than or equal to the pressure signal threshold, indicating that the driver is not in his seat, the steering wheel heating is maintained.

[0080] It should be noted that the following describes the heating control strategy for the vehicle interior temperature and steering wheel temperature to reach the target temperature, taking the user's reservation time of 10 minutes as an example:

[0081] Solution 1: Control the air conditioner to heat at 5 power levels for 10 minutes to reach the target air conditioner temperature T CNY At the 5th minute, the steering wheel temperature rises by 5°C due to the heating effect of the air conditioner. At this time, the steering wheel heater is inserted at the middle power level and heated for 5 minutes to reach the target steering wheel temperature T SWY .

[0082] Solution 2: Control the air conditioner to heat at level 5 for 10 minutes to reach the target air conditioner temperature T CNYAt the 8th minute, the steering wheel temperature rises by 10°C due to the heating effect of the air conditioner. At this time, the steering wheel heater is engaged at high power for 2 minutes to reach the target steering wheel temperature T SWY .
