Description

Technical Field

[0001] The present application relates to the technical field of automobile cabin preheating, and in particular to a control method, device, storage medium and electronic device for automobile cabin preheating. Background Art

[0002] On cold winter mornings, if a user drives out, the cabin temperature is often very low when the user first enters the car, resulting in a very poor user experience. To improve the user's driving experience, it is necessary to install a car cabin preheating system in the car that can accurately control the heating time. However, in the existing technology, on the one hand, there is little research on car cabin preheating, and usually more research is done on the preheating of car seats, rearview mirrors, etc.; on the other hand, in the relevant technologies for car cabin preheating, the heating trigger time of the cabin preheating is usually not accurately controlled, which makes the heating time during the cabin preheating process inaccurate, resulting in heat waste or insufficient heat, thereby reducing the user experience. Based on this, how to improve the accuracy of the car's control of the heating time during the cabin preheating process is a technical problem that needs to be solved urgently.

[0006] In some embodiments of the present application, based on the aforementioned scheme, determining the heating trigger time for cabin preheating according to the reservation data and the basic data includes: determining the detection time of the car's ambient temperature according to the reservation data and the basic data; when the detection time is reached, detecting the interior temperature and the exterior temperature of the car, and determining the interior temperature and the exterior temperature as the car's ambient temperature; and calculating the heating trigger time for cabin preheating according to the car's ambient temperature.

[0007] In some embodiments of the present application, based on the aforementioned scheme, calculating the heating trigger time for cabin preheating using the vehicle ambient temperature includes: determining the required heat and lost heat for cabin preheating based on the vehicle ambient temperature; and determining the heating trigger time for cabin preheating based on the required heat and lost heat.

[0008] In some embodiments of the present application, based on the aforementioned scheme, determining the heating trigger time for cabin preheating based on the required heat and the lost heat includes: determining a theoretical heating trigger time for cabin preheating based on the required heat and the lost heat; obtaining a correction coefficient, the correction coefficient being used to correct the theoretical heating trigger time; and correcting the heating trigger time for cabin preheating by using the correction coefficient.

[0009] In some embodiments of the present application, based on the aforementioned scheme, after controlling the car to preheat the cabin, the method further includes: monitoring the actual temperature of the cabin in real time; when the actual temperature reaches a target temperature, controlling the car to switch to a heat preservation mode, wherein the target temperature is the temperature preset when the user reserves the cabin heating; when the duration of the heat preservation mode exceeds a preset time, controlling the car to exit the cabin preheating.

[0010] In some embodiments of the present application, based on the aforementioned scheme, if a stop operation is detected before the heating trigger time is reached, the car is controlled to cancel the scheduled car cabin heating; if a stop operation is detected between the heating trigger time and the time when the car exits the cabin preheating, the car is controlled to exit the cabin preheating.

[0011] In some embodiments of the present application, based on the aforementioned solution, when the heating trigger time is reached, the car is controlled to preheat the seats and the steering wheel.

[0012] According to a second aspect of an embodiment of the present application, a car cabin preheating device is provided, the device comprising: an acquisition unit for acquiring the user's reservation data and the basic data of the car when it is detected that the user has made a reservation for car cabin heating; a determination unit for determining a heating trigger time for cabin preheating based on the reservation data and the basic data; and a control unit for controlling the car to preheat the cabin when the heating trigger time is reached.

[0013] According to a third aspect of an embodiment of the present application, a computer-readable storage medium is provided, characterized in that at least one program code is stored in the computer-readable storage medium, and the at least one program code is loaded and executed by a processor to implement the operations performed by the method described in any one of the first aspects above.

This indicates that before cabin preheating, the vehicle rigorously calculates and confirms the cabin preheating trigger time based on the user's reservation data and the vehicle's known basic data. This ensures that the cabin preheating only occurs when the precise heating trigger time is reached, thereby improving the accuracy of the cabin preheating duration and, to a certain extent, avoiding heat waste and insufficient heat during cabin preheating, thereby enhancing the user experience.

[0031] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings 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 making creative efforts shall fall within the scope of protection of the present invention.

[0032] The following will describe some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0033] See also Figure 1 , shows a flow chart of a method for controlling vehicle cabin preheating according to an embodiment of the present application, which specifically includes steps 110 to 113:

[0034] Step 110 : When it is detected that the user reserves the car cabin heating, the reservation data of the user and the basic data of the car are obtained.

[0035] In some embodiments, users can set a date, travel time, and preset cabin preheating temperature for their vehicle cabin through a smart mobile device (such as a mobile phone app) or the vehicle's onboard computer. If the user does not set a date or travel time for cabin preheating in the reservation event, the vehicle will consider the reservation event invalid and will not preheat the vehicle's cabin. If the user sets a date and travel time for cabin preheating in the reservation event, but does not set a preset cabin preheating temperature, the vehicle will determine a default preset temperature for the user based on big data and consider the reservation event valid.

[0036] In some embodiments, basic vehicle data includes, but is not limited to, vehicle material property data, vehicle heating system property data, vehicle experimental data, and the like. Specifically, this data may include data on the cooling and heating capacity of the vehicle's air conditioning system, the heating power of the vehicle's air conditioning, the thermal conductivity of the vehicle's window glass, the thermal conductivity of the seats, the thermal conductivity of the instrument panel plastic, the heat transfer area and dimensions of various heat transfer materials within the vehicle, cabin air quality, the specific heat capacity of cabin air, and experimental data on the heating trigger time for cabin preheating.

[0037] It should be noted that the experimental data of the car includes both the raw data obtained during the preheating experiment of the car cabin and the data after processing the raw data. For example, in an experiment, the car cabin is preheated to 26 degrees through the air conditioning and heating system at ambient temperatures of 0 degrees, 10 degrees, and 20 degrees. The initial ambient temperature (0 degrees, 10 degrees, and 20 degrees), the number of settings of the air conditioning and heating system, the target temperature (26 degrees), the preheating time, and other data in the experiment can be used as raw data. By processing the raw data, data such as the heating time for heating to 26 degrees at various temperatures in the range of -10 degrees to 20 degrees can be obtained. Of course, different experimental processes can be designed according to different data needs, and different experimental data can be recorded and processed. This application does not limit this.

[0038] Step 120 : determining a heating trigger time for cabin preheating according to the reservation data and the basic data.

[0039] In some embodiments, a vehicle-side storage and processing controller in the automobile may determine a heating trigger time for cabin preheating based on the reservation data and the basic data.

[0040] In some embodiments, the heating trigger time for cabin preheating is determined based on the reservation data and the basic data, and the following method can be used: Figure 2 Follow the steps shown.

[0041] See also Figure 2 , shows a detailed flow chart of determining the heating trigger time for cabin preheating based on the reservation data and the basic data according to an embodiment of the present application, specifically including steps 121 to 123.

[0042] Step 121 : determining a detection time for the automobile ambient temperature according to the reservation data and the basic data.

[0043] In some embodiments, the vehicle's ambient temperature detection time can be calculated by the vehicle's vehicle-side storage and processing controller based on the reservation data set by the user and the cooling and heating capacity of the vehicle's air-conditioning system. The vehicle's ambient temperature detection time can also be determined based on experimental data. Specifically, there is no limitation in this application.

[0044] In some embodiments, when the vehicle-side storage and processing controller determines the detection time of the vehicle's ambient temperature, it will feed back the detection time to the T-Box. When the detection time arrives, the T-Box wakes up the vehicle computer to detect the vehicle's ambient temperature.

[0045] It should be noted that the detection time is not equal to the heating trigger time for preheating the car cabin. That is, when the detection time is reached, the in-car temperature sensor and the out-car temperature sensor in the car will detect the car's ambient temperature, and will not trigger the heating system in the car to preheat the cabin.

[0046] Step 122: When the detection time arrives, detect the interior temperature and the exterior temperature of the vehicle, and determine the interior temperature and the exterior temperature as the vehicle ambient temperature.

[0047] Step 123 : Calculate a heating trigger time for cabin preheating according to the vehicle ambient temperature.

[0048] In this embodiment, by determining the detection time, the indoor / outdoor temperature of the car is not detected until the detection time is reached, which can avoid directly using the indoor / outdoor temperature of the car when the user's scheduled event occurs as the car's ambient temperature, thereby improving the accuracy of the calculation of the heating trigger time in the car cabin preheating.

[0049] In some embodiments, the heating trigger time for cabin preheating is calculated based on the vehicle ambient temperature, which can be as follows: Figure 3 Follow the steps shown.

[0050] See also Figure 3 , shows a detailed flowchart of calculating the heating trigger time of cabin preheating by the vehicle ambient temperature according to an embodiment of the present application, specifically including steps 1231 to 1232.

[0051] Step 1231 : Determine the required heat and lost heat for cabin preheating according to the vehicle ambient temperature.

[0052] In some embodiments, the cabin preheating heat requirement is the amount of heat required to preheat the vehicle cabin to the preset temperature set by the user; the cabin preheating heat loss is the amount of heat lost to preheat the vehicle cabin to the preset temperature set by the user. It is understood that when a vehicle's heating system (such as the air conditioning system) generates heat, many heat-absorbing materials within the cabin, such as windows and seats, absorb some of the heat generated by the heating system. Therefore, this heat absorbed by the cabin materials is defined as heat loss.

[0053] Step 1232 : Determine a heating trigger time for cabin preheating based on the required heat and the lost heat.

[0054] In some embodiments, the heating trigger time for cabin preheating is determined based on the required heat and the lost heat, which can be as follows: Figure 4 Follow the steps shown.

[0055] See also Figure 4 , shows a detailed flowchart of determining the heating trigger time of the cabin preheating according to the required heat and the lost heat according to an embodiment of the present application, specifically including steps 12321 to 12323.

[0056] Step 12321: Determine a theoretical heating trigger time for cabin preheating based on the required heat and the lost heat.

[0057] Step 12322: Obtain a correction coefficient, where the correction coefficient is used to correct the theoretical heating trigger time.

[0058] Step 12323: Correct the cabin preheating heating trigger time using the correction coefficient.

[0059] In order to enable those skilled in the art to better understand this embodiment, a specific implementation method for determining a heating trigger time for cabin preheating will be provided below.

[0060] Q1=P*t1 Formula (1)

[0061] Among them, Q1 is the heat provided by the car's air-conditioning system; P is the heating power of the air-conditioning system; and t1 is the heating time of the car cabin preheating.

[0062] Q2=C*m(T2-T1) Formula (2)

[0063] Among them, Q2 is the required heat for cabin preheating; C is the specific heat capacity of the air in the cabin; T2 is the user-preset temperature (or the default preset heating temperature); and T1 is the vehicle interior temperature determined at the detection time.

[0064] Q3=∑Ki A i ΔT i / ΔL i Formula (3)

[0065] Among them, Q3 is the heat loss of cabin preheating; K i A is the thermal conductivity of the material in the cabin that absorbs heat (such as the glass material of the window, the plastic material of the instrument panel, etc.); i is the heat transfer area of ​​the material that absorbs heat in the cabin (such as the seat area, etc.); ΔT i ΔL is the temperature difference between the two ends of the material that absorbs heat in the cabin; i The distance between the two ends of the material in the cabin that absorbs heat.

[0066] According to formula (1), formula (2) and formula (3), the heating time of the car cabin preheating is determined as follows:

[0067] t1=(Q2+Q3) / P=(C*m(T2-T1)+∑K i A i ΔT i / ΔL i ) / P formula (4)

[0068] The theoretical heating trigger time of cabin preheating is determined based on the cabin preheating duration:

[0069] t2=t-t1 Formula (5)

[0070] Among them, t2 is the theoretical heating trigger time of cabin preheating; t is the time preset by the user when making an appointment (i.e. travel time); and t1 is the heating time of cabin preheating.

[0071] The heating trigger time of cabin preheating is determined based on the theoretical heating trigger time of cabin preheating:

[0072] t3=α*t2=α*(t-t1) Formula (6)

[0073] Wherein, α is a correction coefficient, and the correction coefficient is used to correct the theoretical heating trigger time to improve the accuracy of the heating trigger time.

[0074] In some embodiments, the correction coefficient is determined based on experimental vehicle data, that is, by processing the raw data obtained from the experiment. A matching correction coefficient may be calibrated for each preset temperature (i.e., target temperature), or a matching correction coefficient may be calibrated for a specific temperature range (i.e., as long as the preset temperature falls within the temperature range, the correction coefficient calibrated for that temperature range is used). In this example, the correction coefficient may be determined by fitting the experimental data to the theoretical heating trigger time data, or by other methods, which are not limited in this application.

[0075] In some embodiments, the theoretical heating trigger time t2 for cabin preheating determined in equation (5) may be determined as the heating trigger time for cabin preheating, that is, when the theoretical heating trigger time t2 is reached, the vehicle is controlled to preheat the cabin.

[0076] In other embodiments, the cabin preheating heating trigger time t3 determined in formula (6) may be determined as the cabin preheating heating trigger time, that is, when the heating trigger time t3 is reached, the vehicle is controlled to preheat the cabin.

[0077] It can be understood that if the heating trigger time t3 for cabin preheating determined in formula (6) is used as the heating trigger time for cabin preheating, then because a correction coefficient is introduced in formula (6) to correct the theoretical heating trigger time, and the correction coefficient is determined by processing experimental data, then the accuracy of the heating trigger time can be improved to a certain extent.

[0078] Step 130 : When the heating trigger time is reached, control the vehicle to preheat the cabin.

[0079] In some embodiments, when the heating trigger time is reached, the vehicle is controlled to preheat the seats and steering wheel. The steering wheel is preheated by the steering wheel heating system, the seats are preheated by the seat heating system, and the cabin is preheated by the air conditioning system. When the heating trigger time is reached, the vehicle's T-Box wakes up the vehicle to preheat the cabin, steering wheel, and seats.

[0080] In some embodiments, after controlling the car to preheat the cabin, the car monitors the actual temperature of the cabin in real time; when the actual temperature reaches a target temperature, the car is controlled to switch to a heat preservation mode, where the target temperature is the temperature preset when the user reserved cabin heating; when the heat preservation mode lasts for more than a preset time, the car is controlled to exit the cabin preheating.

[0081] In some embodiments, when controlling the automobile to preheat the cabin, the air conditioning system, steering wheel heating system, and seat heating system may be set to maximum capacity to heat the cabin, steering wheel, and seats. When the actual cabin temperature reaches the target temperature, the air conditioning system may be switched to minimum capacity to adapt to a heat preservation mode and save energy.

[0082] It should be noted that the preset duration of the keep warm mode can be set to 10 minutes, 20 minutes, or 30 minutes, and the specific preset duration is not limited in this application. When the car exits the cabin preheating, the car can remind the user that the cabin preheating has been exited through a text message, a smart mobile terminal, or the car computer.

[0083] In this embodiment, when the vehicle detects that the actual cabin temperature is at the target temperature, it indicates that the user's preset time (i.e., departure time) has been reached, or is near the user's preset time. At this point, the vehicle's cabin preheating mode is switched to a warming mode, which prevents heat waste and improves the user's comfort upon entering the vehicle. When the warming mode lasts longer than the preset duration, the vehicle is controlled to exit cabin preheating, preventing heat waste if the user has not yet boarded the vehicle after the set departure time.

[0084] In some embodiments, if a stop operation is detected before the heating trigger time is reached, the car is controlled to cancel the scheduled car cabin heating; if a stop operation is detected between the heating trigger time and the time the car exits the cabin preheating, the car is controlled to exit the cabin preheating.

[0085] It should be noted that a touch-stop operation can occur when the user opens the driver's door and the vehicle enters the starting state, or when the user operates the vehicle's air conditioning system, the user operates the seat heating switch, or the user operates the steering wheel heating switch. When the vehicle exits the cabin preheating mode, the air conditioning system, seat heating system, and steering wheel heating system will be switched to the memory state or to the adjusted state.

[0086] It is understood that if the user performs a stop operation before the cabin preheating trigger time, the cabin preheating reservation will be invalidated, and the vehicle will cancel the reservation time and simultaneously notify the user of the cancellation via text message, smart mobile terminal, or vehicle computer. If a stop operation is detected between the heating trigger time and the vehicle's exit from cabin preheating, that is, during cabin preheating or while in keep-warm mode, the vehicle will exit cabin preheating and stop heating the cabin. The user will be notified of the exit via text message, smart mobile terminal, or vehicle computer.

[0087] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application will be described below from the overall process.

[0088] See also Figure 5 , shows an overall flow chart of a method for controlling automobile cabin preheating according to an embodiment of the present application, specifically including steps 500 to 560.

[0089] Step 500: When it is detected that a user reserves a car cabin heating reservation, the reservation data of the user and the basic data of the car are obtained;

[0090] Step 510 , determining a heating trigger time for cabin preheating based on the reservation data and the basic data;

[0091] Step 520 , when the heating trigger time is reached, controlling the vehicle to preheat the cabin;

[0092] Step 530 , monitoring the actual cabin temperature in real time, and controlling the vehicle to switch to a heat preservation mode when the actual cabin temperature reaches a target temperature, wherein the target temperature is the temperature preset when the user pre-sets cabin heating;

[0093] Step 540: When the duration of the insulation mode exceeds a preset time, the vehicle is controlled to exit the cabin preheating.

[0094] Step 550 , if a stop operation is detected before the heating trigger time is reached, controlling the vehicle to cancel the scheduled vehicle cabin heating;

[0095] Step 560: If a touch-stop operation is detected between the heating trigger time and the vehicle exiting the cabin preheating, control the vehicle to exit the cabin preheating.

[0096] In the technical solutions provided in some embodiments of the present application, during cabin preheating, when a user is detected to have reserved cabin heating, the vehicle obtains the user's reservation data and the vehicle's basic data; determines a heating trigger time for cabin preheating based on the reservation data and the basic data; and controls the vehicle to preheat the cabin when the heating trigger time arrives. This indicates that before cabin preheating, the vehicle rigorously calculates and confirms the cabin preheating trigger time based on the user's reservation data and the vehicle's known basic data. This ensures that the vehicle preheats the cabin only when the precise heating trigger time arrives. This improves the accuracy of the cabin preheating duration, avoids heat waste and insufficient heat during cabin preheating, and enhances the user experience.
