Technical Field

[0002] This application relates to the field of vehicle technology, and in particular to a method, apparatus, computer device, computer-readable storage medium, and computer program product for opening a vehicle door handle. Background Technology

[0003] As user demands continue to rise, making the overall appearance of a vehicle simpler and more streamlined, thereby enhancing its sense of style, technology, and sophistication, has become a key research focus for designers.

[0004] In the design of vehicle door handles, concealed door handles are often used instead of traditional door handles. When opening a concealed door handle, it can be opened by the user's actual operation or remotely via network technology. However, due to the performance limitations of the concealed door handle itself, it cannot be opened normally when the ambient temperature of the vehicle is below a certain temperature threshold. Therefore, how to open a concealed door handle in a low-temperature environment is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] Therefore, it is necessary to provide a method, device, computer equipment, computer-readable storage medium, and computer program product for opening a vehicle door handle that can open a concealed door handle in a low-temperature environment, in order to address the above-mentioned technical problems.

[0007] Receives a touch sensing signal sent by an elastic wave sensor, the touch sensing signal being generated when the elastic wave sensor detects a user touch operation;

[0008] Based on the touch sensing signal, the vehicle's door handle is controlled to open;

[0009] If the door handle fails to open, determine whether the number of received touch sensing signals exceeds a preset first number threshold.

[0010] If the first quantity threshold is exceeded, the door handle is heated for a preset heating time, and the door handle is opened after heating is completed.

[0011] In one embodiment, the heating operation of the door handle according to a preset heating time includes:

[0012] Determine whether the number of received touch sensing signals exceeds a preset second threshold.

[0013] If the quantity exceeds the second threshold, the door handle is heated for a preset first heating time.

[0014] Without exceeding the second quantity threshold, the environmental parameters of the vehicle's environment are obtained, and a target heating time is selected from the preset second heating time based on the environmental parameters. The door handle is then heated according to the target heating time.

[0015] In one embodiment, obtaining the environmental parameters of the environment in which the vehicle is located includes:

[0016] Receives the ambient temperature of the vehicle's surroundings from the temperature sensor;

[0017] Receives the ambient humidity of the vehicle's surroundings from the humidity sensor;

[0018] The ambient temperature and the ambient humidity are used as the environmental parameters.

[0019] In one embodiment, receiving the touch sensing signal sent by the elastic wave sensor includes:

[0020] Detect the unlock signal of the vehicle;

[0021] Upon detecting the unlock signal, the touch sensing signal sent by the elastic wave sensor is received.

[0022] In one embodiment, the method further includes:

[0023] If the number of received touch sensing signals does not exceed the first quantity threshold, the step of detecting the unlock signal of the vehicle is returned and execution continues until the number of received touch sensing signals exceeds the preset first quantity threshold.

[0024] In one embodiment, after controlling the door handle to open after the door handle has finished heating, the method includes:

[0025] If the door handle still fails to open, return to the step of determining whether the number of received touch sensing signals exceeds a preset first threshold number, until the door handle opens successfully.

[0026] Secondly, this application also provides a door handle opening device for a vehicle, the device comprising:

[0027] A receiving module is used to receive touch sensing signals sent by an elastic wave sensor, wherein the touch sensing signals are generated when the elastic wave sensor detects a user touch operation;

[0028] A control module is used to control the opening of the vehicle's door handle based on the touch sensing signal;

[0029] The judgment module is used to determine whether the number of received touch sensing signals exceeds a preset first number threshold when the door handle fails to open.

[0030] The heating module is used to heat the door handle for a preset heating time when the quantity exceeds the first threshold, and to control the door handle to open after the door handle is heated.

[0031] Thirdly, this application also provides a computer device, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the steps of the methods of various embodiments.

[0034] The aforementioned vehicle door handle opening method, device, computer equipment, computer-readable storage medium, and computer program product can receive touch sensing signals sent by an elastic wave sensor. The touch sensing signals are generated when the elastic wave sensor detects a user touch operation. Based on the touch sensing signals, the door handle of the vehicle is controlled to open. If the door handle fails to open, it is assumed that there is a situation where the hidden door handle cannot be opened in a low-temperature environment. It can then determine whether the number of received touch sensing signals exceeds a preset first quantity threshold. If it exceeds the first quantity threshold, the door handle is heated for a preset heating time, and the door handle is controlled to open after heating is completed. This achieves heating of the door handle in a low-temperature environment, thereby enabling the door handle to be controlled to open after heating, solving the problem of how to open a hidden door handle in a low-temperature environment.

[0041] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0042] In one embodiment, as shown in FIG1, a method for opening a vehicle door handle is provided. This embodiment illustrates the application of this method to a vehicle controller. In this embodiment, the method includes the following steps:

[0043] Step 102: Receive the touch sensing signal sent by the elastic wave sensor. The touch sensing signal is generated when the elastic wave sensor detects the user's touch operation.

[0044] In this embodiment, the elastic wave sensor is a skin sensor that works by monitoring minute deformations caused by impact or pressure on the surface of an object. When the elastic wave sensor detects a user's touch operation, it generates a spectrum signal based on the detected signal, uses the frequency signal as the touch sensing signal, and sends the touch sensing signal to the vehicle's controller. The controller can then analyze the touch sensing signal and extract useful information.

[0045] Elastic wave sensors can be installed in vehicle door handles or in other areas of the vehicle.

[0046] When the elastic wave sensor is installed in the vehicle door handle, the user touch operation can be: the user presses the vehicle door handle and the pressing time exceeds a preset pressing time threshold, or the user slides on the vehicle door handle and the sliding time exceeds a preset sliding time threshold.

[0047] In this embodiment, the vehicle door handle can be a concealed handle, which is embedded in the door panel, or it can be designed using methods such as slant or groove to make the vehicle look simple and neat.

[0048] In this embodiment, the elastic wave sensor differs significantly from traditional pressure sensors. The elastic wave sensor primarily converts the sensed user operation signal into a spectral signal, outputting spectral data. In contrast, the pressure sensor, after sensing a user operation, typically outputs a direct electrical signal, which can be directly read and converted into a pressure value to determine the pressure change.

[0049] Step 104: Based on the touch sensing signal, control the vehicle's door handle to open;

[0050] The controller uses useful information from the extracted touch sensing signals to control the opening of the vehicle's door handles;

[0051] It should be noted that if the ambient temperature of the vehicle is below the temperature threshold, the concealed door handle may freeze and become unusable. Therefore, after attempting to open the vehicle's door handle, there is a possibility that the door handle may fail to open.

[0052] Step 106: If the door handle fails to open, determine whether the number of received touch sensing signals exceeds a preset first threshold.

[0053] Before the controller receives the current touch sensing signal sent by the elastic wave sensor, the elastic wave sensor may detect the user's touch operation once or multiple times and generate touch sensing signals to send to the elastic wave sensor. Therefore, the number of received touch sensing signals refers to the total number of the current touch sensing signals received and the number of one or more touch sensing signals received by the elastic wave sensor before the time of receiving the current touch sensing signal.

[0054] For example, if the elastic wave sensor received 5 touch sensing signals before receiving the current touch sensing signal, and then adds the current touch sensing signal, the total number of touch sensing signals received is 6.

[0055] Step 108: If the first quantity threshold is exceeded, heat the door handle for a preset heating time, and control the door handle to open after the door handle is heated.

[0056] In this embodiment, a preset heating duration can be selected from multiple preset heating durations based on the number of received touch sensing signals, and the door handle can be heated according to the selected preset heating duration;

[0057] The preset heating time can vary depending on the number of touch sensing signals received.

[0058] In this embodiment, a heating wire can be installed in the door handle of the vehicle. When the number of received touch sensing signals exceeds a first quantity threshold, the controller controls the heating wire to heat up, thereby heating the door handle.

[0059] The controller can communicate with the drive motor controller. The controller sends a signal to the drive motor controller to open the door handle. The drive motor controller then sends the signal to the drive motor, which controls the door handle to unfold laterally to a specified unfolding angle.

[0060] Of course, in the scenario of closing the door handle, the drive motor can also control the door handle to retract to a specified retraction angle.

[0061] This application can receive touch sensing signals sent by an elastic wave sensor. The touch sensing signals are generated when the elastic wave sensor detects a user touch operation. Based on the touch sensing signals, the application controls the opening of the vehicle's door handle. If the door handle fails to open, it is assumed that the hidden door handle cannot be opened in a low-temperature environment. The application can then determine whether the number of received touch sensing signals exceeds a preset first threshold. If the number exceeds the first threshold, the application heats the door handle for a preset heating time and controls the door handle to open after heating is complete. This enables the door handle to be heated in a low-temperature environment, thus solving the problem of how to open a hidden door handle in a low-temperature environment.

[0062] In one embodiment, heating the door handle according to a preset heating time includes: determining whether the number of received touch sensing signals exceeds a preset second quantity threshold; if the number exceeds the second quantity threshold, heating the door handle according to a preset first heating time; if the number does not exceed the second quantity threshold, obtaining environmental parameters of the vehicle's environment, selecting a target heating time from the preset second heating time based on the environmental parameters, and heating the door handle according to the target heating time.

[0063] If the number of received touch sensing signals exceeds the preset first number threshold, it is further determined whether the number of received touch sensing signals exceeds the preset second number threshold. If it exceeds the second number threshold, the heating operation is directly performed on all door handles (or door handles touched by the user) in the vehicle according to the preset first heating time, and the corresponding door handle is controlled to open after the door handle is heated.

[0064] Without exceeding a second quantity threshold, environmental parameters of the vehicle's environment are acquired. In this embodiment, the environmental parameters of the vehicle's environment include ambient temperature and / or ambient humidity.

[0065] The preset second heating duration includes at least two heating durations, specifically including the first heating duration; a target heating duration corresponding to the environmental parameter can be selected from the preset second heating duration based on the environmental parameter, thereby heating the door handle for the target heating duration.

[0066] The target heating duration corresponding to this environmental parameter can be the first heating duration.

[0067] In this embodiment, the target heating time can be different for different environmental parameters. Specifically:

[0068] When the ambient temperature is within the range of T1 to T2 and the ambient humidity is within the range of RH1 to RH2, the first heating time is selected from the preset second heating time; for example, T1 to T2 can be -1℃ to 2℃, RH1 to RH2 can be 60% to 80%, and the first heating time is 5 minutes.

[0069] When the ambient temperature is within the range of T2 to T3 and the ambient humidity is within the range of RH2 to RH3, a third heating time is selected from the preset second heating time, and the third heating time is longer than the first heating time. For example, T2 to T3 can be -15℃ to -1℃, RH2 to RH3 can be 80% to 100%, and the third heating time is 10 minutes.

[0070] As can be seen, based on the number of received touch sensing signals and environmental parameters, this application can determine the corresponding preset heating time, thereby heating the door handle according to different preset heating times, and realizing precise control of the door handle heating time.

[0071] In existing vehicles using concealed door handles, the system monitors whether the vehicle needs to heat the door handles to ensure they pop out automatically, based on the vehicle network status and environmental parameters. However, this solution obtains environmental parameters through an information platform and heats the door handles before the user approaches the vehicle, requiring significant network connection resources. Furthermore, it cannot monitor environmental parameters based on actual vehicle scenarios, resulting in inaccurate environmental parameters.

[0072] In one embodiment, obtaining the environmental parameters of the vehicle's environment includes: receiving the ambient temperature of the vehicle's environment from a temperature sensor; receiving the ambient humidity of the vehicle's environment from a humidity sensor; and using the ambient temperature and the ambient humidity as the environmental parameters.

[0073] This application allows the installation of an environment temperature (T) sensor and an environment humidity (RH) sensor on a vehicle. The temperature sensor can detect the ambient temperature of the vehicle's environment in real time, and the humidity sensor can detect the ambient humidity of the vehicle's environment in real time. The temperature sensor sends the detected ambient temperature to the controller, and the humidity sensor sends the detected ambient humidity to the controller. The controller uses the ambient temperature and ambient humidity as environmental parameters.

[0074] As can be seen, this application can monitor real-time environmental parameters through temperature and humidity sensors, enabling the detection of environmental parameters in actual vehicle scenarios and improving the accuracy of environmental parameter detection. Consequently, the determined heating time for the door handle is also more accurate. Furthermore, environmental parameters can be detected directly through sensors installed on the vehicle, eliminating the need for high network connectivity resources to obtain environmental parameters from an information platform, thus reducing network connection requirements.

[0075] As mentioned above, if the number of received touch sensing signals does not exceed a preset first threshold, the touch sensing signals sent by the elastic wave sensor can be received repeatedly until the preset first threshold is exceeded, at which point the door handle is heated to open the door handle. Specifically:

[0076] In one embodiment, receiving the touch sensing signal sent by the elastic wave sensor includes: detecting the unlock signal of the vehicle; and, if the unlock signal is detected, receiving the touch sensing signal sent by the elastic wave sensor.

[0077] In one embodiment, the method further includes: if the number of received touch sensing signals does not exceed the first quantity threshold, returning to the step of detecting the unlock signal of the vehicle and continuing to execute until the number of received touch sensing signals exceeds the preset first quantity threshold.

[0078] The controller detects the vehicle's unlock signal, specifically including: the door lock controller senses the key signal and controls whether the vehicle is unlocked or locked; after the door lock controller detects that the vehicle is unlocked, it sends the vehicle's unlock signal to the controller.

[0079] The system detects the vehicle's unlock signal. Upon detection, it receives a touch-sensing signal from a spring wave sensor. Based on this signal, it controls the vehicle's door handle to open, determining if the door handle opened successfully. If the door handle failed to open, it checks if the number of received touch-sensing signals exceeds a preset first threshold. If the number does not exceed the first threshold, it returns to the previous loop, repeating the following steps: Detecting the vehicle's unlock signal; Upon detection, it receives a touch-sensing signal from a spring wave sensor. Based on this signal, it controls the vehicle's door handle to open, determining if the door handle opened successfully. If the door handle failed to open, it checks if the number of received touch-sensing signals exceeds a preset first threshold, until the number of received touch-sensing signals exceeds the preset first threshold or the door handle is successfully opened. If the number exceeds the first threshold, it heats the door handle for a preset heating time and controls the door handle to open after heating is complete.

[0080] As can be seen, this application can repeatedly receive touch sensing signals sent by the elastic wave sensor when the number of received touch sensing signals does not exceed a preset first number threshold, thereby heating the door handle before opening it and avoiding the situation where the door handle is opened by accidental touch of the user.

[0081] Meanwhile, this application needs to detect the vehicle's unlock signal in each cycle. Only when the unlock signal is detected will it receive the touch sensing signal sent by the elastic wave sensor, thereby preventing the vehicle from accidentally opening the door handle when it is not unlocked and ensuring driving safety.

[0082] In this application, if the door handle still cannot be opened after being heated for a preset heating time, it can be heated again to open it. Specifically:

[0083] In one embodiment, after the door handle is heated and then controlled to open, the method includes: if the door handle still fails to open, returning to the step of determining whether the number of received touch sensing signals exceeds a preset first number threshold, until the door handle opens successfully.

[0084] Determine whether the door handle was successfully opened. If the door handle was still successfully opened, end the loop.

[0085] If the door handle still fails to open, the following steps are executed repeatedly: determine whether the number of received touch sensing signals exceeds a preset first number threshold; if it exceeds the first number threshold, heat the door handle for a preset heating time, and control the door handle to open after the door handle is heated, until the door handle opens successfully.

[0086] In this embodiment, when the process of repeatedly determining whether the number of received touch sensing signals exceeds a preset first threshold is executed, no new touch sensing signals are received from the elastic wave sensor, and the number of received touch sensing signals does not change. That is, the number of received touch sensing signals remains unchanged in each cycle and still exceeds the first threshold.

[0087] Similarly, the specific implementation of heating the door handle according to the preset heating time is described in the corresponding embodiment above, and will not be repeated here.

[0088] As can be seen, after the door handle is heated for the first time according to the preset heating time, if the door handle still cannot be opened, the application will repeatedly execute the step of judging whether the number of received touch sensing signals exceeds the preset first number threshold, so as to heat the door handle again or multiple times according to the preset heating time, thereby ensuring that the door handle can be opened normally.

[0089] Referring to Figure 2, which is a structural diagram of the vehicle of this application, the vehicle includes a door lock controller, a temperature and humidity sensor, a skin sensor controller (also called an elastic wave controller, the skin sensor controller corresponds to the controller mentioned above), a drive motor controller, a drive motor, four skin sensors (i.e., elastic wave sensors), a heating wire, and a display screen. The four skin sensors, the heating wire, and the display screen are integrated and installed on the door handle.

[0090] A skin sensor is installed on the door handle to detect changes in door handle pressure and transmits the sliding sensing signal to the skin controller. A heating wire is also installed on the door handle and heats it upon receiving a heating signal. The drive motor receives a drive motor control signal to control the door handle to open or close laterally. The drive motor controller interacts with the skin sensor controller to determine the door handle's open state. A temperature and humidity sensor detects the ambient temperature and humidity of the vehicle in real time and transmits the signal to the skin sensor controller. The door lock controller senses the key signal and controls whether the vehicle is unlocked or locked. The skin sensor controller controls whether the door handle is opened and whether heating is required based on the door handle's open state, ambient temperature, ambient humidity, door lock status, and skin sensor signal status. A display screen indicates whether the door handle is heating.

[0091] The skin sensor controller collects all skin sensor signals, performs logic processing, and outputs corresponding electrical signals; the door lock controller monitors the vehicle key signal, determines whether there is a need to unlock the door, and unlocks the vehicle or puts it into an unlockable state.

[0092] Figure 3 shows a flowchart of the overall scheme of this application. The overall scheme is as follows:

[0093] The controller detects the key unlock signal; if no key unlock signal is detected, the loop of sensing finger swipe ends.

[0094] If a key unlock signal is detected, the skin sensor senses the pressure of the door handle or the sliding of a finger. If no pressure of the door handle or the sliding of a finger is sensed, the cycle of sensing the sliding of a finger ends.

[0095] If pressure on the door handle or a finger slip is detected, it is determined whether the drive motor drives the door handle to the specified opening angle. If the drive motor drives the door handle to the specified opening angle, the cycle of detecting finger slip ends.

[0096] If the drive motor fails to move the door handle to the specified opening angle, then determine whether the user has slid the door once or twice.

[0097] If the user swipes once or twice, the finger swipe loop is executed, which includes the following steps: detecting a key unlock signal; if no key unlock signal is detected, the finger swipe detection loop ends; if a key unlock signal is detected, the skin sensor detects door handle pressure or finger swipe; if neither door handle pressure nor finger swipe is detected, the finger swipe detection loop ends; if door handle pressure or finger swipe is detected, it is determined whether the drive motor drives the door handle to the specified opening angle; if the drive motor drives the door handle to the specified opening angle, the finger swipe detection loop ends; if the drive motor does not drive the door handle to the specified opening angle, it is determined whether the user swipes once or twice, until the determination result is that the user swipes more than twice.

[0098] If the user swipes more than twice, the system checks if the user has swiped more than three times. If the user swipes more than three times, the four door handles will heat up according to the heating time 1, and the display will show that the door handles are heating up and please wait.

[0099] If the user swipes three times, the ambient temperature is obtained through the temperature sensor and the ambient humidity is obtained through the humidity sensor. It is then determined whether the ambient temperature meets the heating requirements. If so, heating will proceed according to heating time 2 when the ambient temperature is in the range of T2 to T3 and the ambient humidity is in the range of RH2 to RH3. When the ambient temperature is in the range of T1 to T2 and the ambient humidity is in the range of RH1 to RH2, heating will proceed according to heating time 1. At the same time, the display screen will show that the door handle is heating and please wait.

[0100] Whether the four door handles are heated according to heating time 1, or according to heating time 2 when the ambient temperature is between T2 and T3 and the ambient humidity is between RH2 and RH3, or according to heating time 1 when the ambient temperature is between T1 and T2 and the ambient humidity is between RH1 and RH2, after heating is complete, it is necessary to return to determine whether the drive motor has driven the door handle to the specified opening angle. If the door handle has reached the specified opening angle, the heating cycle ends; if the door handle has not reached the specified opening angle, the heating cycle begins. The heating cycle specifically includes the following steps: determining whether the user has swiped the door more than three times; if... If the user swipes the door handle more than three times, the four door handles will heat for the specified duration (time1), and the display will show "Heating door handles, please wait." If the user swipes the door handle three times, the ambient temperature and humidity will be measured by a temperature sensor and a humidity sensor, respectively. If the ambient temperature meets the heating requirements, heating will proceed for the specified duration (time2) if the ambient temperature is between T2 and T3 and the ambient humidity is between RH2 and RH3. If the ambient temperature is between T1 and T2 and the ambient humidity is between RH1 and RH2, heating will proceed for the specified duration (time1), and the display will show "Heating door handles, please wait."

[0101] For example, if the number of received touch sensing signals is 4, which exceeds the preset first threshold 2 and the preset second threshold 3, then the four door handles are heated for a heating time of time1. After heating, if the door handles still have not opened to the specified opening angle, the heating cycle is returned. At this time, the number of received touch sensing signals is still 4, which exceeds the preset first threshold 2 and the preset second threshold 3. Then the four door handles are heated for a heating time of time1. After heating, it is determined that the door handles have opened to the specified opening angle. Therefore, the total heating time of the door handles is time1 + time1.

[0102] In this embodiment, T1 to T2 can be -1℃ to 2℃, T2 to T3 can be -15℃ to -1℃, RH1 to RH2 can be 60% to 80%, RH3 to RH2 can be 100% to 80%, Timer1 can be 5 minutes, and Timer2 can be 10 minutes.

[0103] As can be seen, this application integrates four small aircraft skin sensors and controllers into an existing vehicle, enabling more compact and efficient door handle opening and low-temperature heating functions. It solves the problem of how to open hidden door handles in low-temperature environments without requiring a high-quality network environment.

[0104] This application can determine the heating time of the door handle based on the real-time collected ambient temperature and humidity. It can collect the ambient temperature and humidity of the actual vehicle scene, and the collected environmental parameters are more accurate, so the determined heating time is also more accurate.

[0105] This application uses aircraft skin sensor sliding technology to monitor changes in door handle pressure, allowing for one or multiple slides to customize door handle opening and heating requirements; at the same time, this application does not require additional holes or buttons on the door handle, does not increase the size of the door handle, and does not affect the aesthetics.

[0106] Compared to door handles unlocked by passwords, mechanical buttons, or remote network access, this application unlocks the door handle by detecting user touch input using a spring wave sensor, which is more convenient. Compared to voice recognition or contactless radio frequency identification (NFC) keys, this application, by installing a spring wave sensor on the door handle, is also more cost-effective.

[0107] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0108] Based on the same inventive concept, this application also provides a vehicle door handle opening device for implementing the vehicle door handle opening method described above. The solution provided by this device is similar to the solution described in the above method; therefore, the specific limitations of one or more vehicle door handle opening device embodiments provided below can be found in the limitations of the vehicle door handle opening method described above, and will not be repeated here.

[0109] In an exemplary embodiment, as shown in FIG4, a vehicle door handle opening device 400 is provided, comprising:

[0110] The receiving module 401 is used to receive the touch sensing signal sent by the elastic wave sensor, which is generated when the elastic wave sensor detects a user touch operation.

[0111] Control module 402 is used to control the door handle of the vehicle to open based on the touch sensing signal;

[0112] The judgment module 403 is used to determine whether the number of received touch sensing signals exceeds a preset first number threshold when the door handle fails to open.

[0113] The heating module 404 is used to heat the door handle for a preset heating time when the first quantity threshold is exceeded, and to control the door handle to open after the door handle is heated.

[0114] In one embodiment, when the heating module 404 heats the door handle according to a preset heating duration, it is specifically used for:

[0115] Determine whether the number of received touch sensing signals exceeds a preset second threshold.

[0116] If the quantity exceeds the second threshold, the door handle is heated for a preset first heating time.

[0117] Without exceeding the second quantity threshold, the environmental parameters of the vehicle's environment are obtained, and a target heating time is selected from the preset second heating time based on the environmental parameters. The door handle is then heated according to the target heating time.

[0118] In one embodiment, when the heating module 404 acquires the environmental parameters of the environment in which the vehicle is located, it is specifically used for:

[0119] Receives the ambient temperature of the vehicle's surroundings from the temperature sensor;

[0120] Receives the ambient humidity of the vehicle's surroundings from the humidity sensor;

[0121] The ambient temperature and the ambient humidity are used as the environmental parameters.

[0122] In one embodiment, the receiving module 401 is specifically used for:

[0123] Detect the unlock signal of the vehicle;

[0124] Upon detecting the unlock signal, the touch sensing signal sent by the elastic wave sensor is received.

[0125] In one embodiment, the device further includes:

[0126] The first loop module is used to return to the step of detecting the unlock signal of the vehicle and continue to execute it if the number of received touch sensing signals does not exceed the first quantity threshold, until the number of received touch sensing signals exceeds the preset first quantity threshold.
