Description

Technical Field

[0001] This application relates to the field of intelligent vehicles, and more specifically, to a control method, device, and vehicle. Background Technology

[0002] Some vehicles are now equipped with a knock-to-open hood function, where tapping the hood will trigger its opening. However, due to the vehicle's environment, there is a certain probability that the hood will be accidentally opened in some situations, resulting in a poor user experience. Summary of the Invention

[0003] This application provides a control method, device, and vehicle that helps reduce the probability of accidental triggering of cover panels with knock-open functions on certain external configurations, thereby improving the user's driving experience.

[0004] In a first aspect, a control method is provided, the method comprising: acquiring a first tapping signal and first sensing data when the first tapping signal is acquired, the first sensing data being used to determine whether there are personnel within a preset range outside the cockpit; and controlling a cover plate located outside the cockpit based on the first tapping signal and the first sensing data.

[0005] Based on the above technical solution, the cover is controlled by combining tapping signals and sensor data from outside the cabin. This reduces the probability of the cover being accidentally opened in certain scenarios (such as rain, snow, hail, falling branches, or other objects falling on the cover), avoiding the cumbersome operation of the user getting out of the vehicle to close the cover after it is accidentally opened. This helps to improve the vehicle's intelligence and enhance the user experience.

[0006] Taking the hood as an example, based on the above technical solution, it can avoid property loss for users and the safety hazards caused by the hood being accidentally triggered to open when encountering the above scenarios during driving, thus helping to improve the driving safety of users.

[0007] In some possible implementations, the tapping signal can be a signal collected by an elastic wave sensor near the cover plate, or the tapping signal can be a signal collected by an elastic wave sensor on the cover plate.

[0008] In some possible implementations, the first sensor data is data collected by one or more of a camera, ultrasonic radar, lidar, or millimeter-wave radar outside the vehicle cabin.

[0009] In some possible implementations, the impact signal is a signal collected by an elastic wave sensor located near the cover plate. This impact signal can also be referred to as an elastic wave signal.

[0010] In some possible implementations, the cover can be a hood, fuel filler cap, charging port cap, side door, or tailgate. The vehicle can be equipped with a tap-to-open function for the cover, such as a double-tap function.

[0011] In some possible implementations, acquiring the first tapping signal and the first sensing data when acquiring the first tapping signal includes: acquiring the first sensing data when the characteristic parameters of the first tapping signal meet preset conditions.

[0012] In some possible implementations, acquiring the first sensing data at the time of the first tapping signal includes: acquiring sensing data collected within a period of time prior to the first tapping signal; or, acquiring sensing data collected at the time of the first tapping signal; or, acquiring sensing data collected within a period of time after the first tapping signal.

[0013] In some possible implementations, the preset range is related to the position of the cover. Taking the cover as a front hatch as an example, the preset range can be a range of 1 meter in front of the vehicle.

[0014] In conjunction with the first aspect, in some implementations of the first aspect, controlling the cover plate according to the first tapping signal and the first sensing data includes: controlling the cover plate to open when the characteristic parameters of the first tapping signal meet preset conditions and the first sensing data indicates that there are personnel within the preset range.

[0015] Based on the above technical solution, the cover can be opened when there are people within the preset range and the tapping signal meets the preset conditions. This can improve the accuracy of cover opening in certain scenarios (such as rain, snow, hail, falling branches, or other objects falling on the cover), avoid the cumbersome operation of the user getting out of the vehicle to close the cover after accidental opening, help improve the vehicle's intelligence level, and also help improve the user experience.

[0016] In some possible implementations, the characteristic parameters of the first tapping signal satisfy preset conditions, including: the characteristic parameters of the first tapping signal satisfy the characteristic parameters of the tapping signal generated when a finger taps the cover plate.

[0017] In some possible implementations, the characteristic parameters of the first striking signal include at least one of the amplitude, frequency, phase, and duration of the first striking signal.

[0018] In conjunction with the first aspect, in some implementations of the first aspect, before controlling the opening of the cover, the method further includes: obtaining, based on the first sensing data, the action of the person knocking on the cover.

[0019] Based on the above technical solution, the cover can be opened only when a person performs a tapping action within a preset range and the tapping signal meets preset conditions. This can further improve the accuracy of cover opening in certain scenarios (e.g., rain, snow, hail, falling branches, or other objects falling onto the cover), avoiding the cumbersome operation of the user getting out of the vehicle to close the cover after accidental opening, thus helping to improve the vehicle's intelligence and enhance the user experience.

[0020] In conjunction with the first aspect, in some implementations of the first aspect, before controlling the opening of the cover, the method further includes: determining that the biometric information of the person matches the biometric information stored in the vehicle.

[0021] Based on the above technical solution, when a person matching the biometric information stored in the vehicle performs a tapping action on the cover within a preset range, and the tapping signal meets preset conditions, the cover can be controlled to open. This further improves the accuracy of cover opening in certain scenarios (e.g., rain, snow, hail, falling branches, or other objects falling onto the cover), avoiding the cumbersome operation of the user getting out of the vehicle to close the cover after accidental opening, thus enhancing the vehicle's intelligence and improving the user experience.

[0022] In some possible implementations, before determining that the person's biometric information matches the biometric information stored in the vehicle, the method includes: acquiring an image within a preset range; determining that the person's biometric information matches the biometric information stored in the vehicle, including: determining that the facial features in the image match the facial features of one or more users stored in the vehicle.

[0023] In some possible implementations, before determining that the biometric information of the person matches the biometric information stored in the vehicle, the method includes: acquiring the voiceprint information of the person within the preset range; determining that the biometric information of the person matches the biometric information stored in the vehicle, including: determining that the facial features in the voiceprint information match the voiceprint features of one or more users stored in the vehicle.

[0024] In conjunction with the first aspect, in some implementations of the first aspect, controlling the cover plate according to the first tapping signal and the first sensing data includes: controlling the cover plate to remain closed when the characteristic parameters of the first tapping signal meet preset conditions and the first sensing data indicates that there are no personnel within the preset range.

[0025] Based on the above technical solution, the cover can be kept closed when there are no people within the preset range and the tapping signal meets the preset conditions. This reduces the probability of the cover being accidentally opened in certain scenarios (e.g., rain, snow, hail, falling branches, or other objects falling onto the cover), avoiding the cumbersome operation of the user getting out of the vehicle to close the cover after it is accidentally opened. This helps improve the vehicle's intelligence level and also enhances the user experience.

[0026] In some possible implementations, controlling the cover plate based on the first tapping signal and the first sensing data includes: controlling the cover plate to remain closed when the characteristic parameters of the first tapping signal do not meet preset conditions.

[0027] In conjunction with the first aspect, in some implementations of the first aspect, the method further includes: when the characteristic parameters of the first tapping signal satisfy the preset condition and the first sensing data indicates that there is no person within the preset range for a cumulative duration greater than or equal to the first preset duration, the acquired tapping signal is ignored within the second preset duration.

[0028] Based on the above technical solution, after the characteristic parameters of the tapping signal meet the preset conditions and the cumulative duration of no personnel within the preset range is greater than or equal to the first preset duration, the vehicle can ignore the acquired tapping signal within the second preset duration. Alternatively, the vehicle can control the cover not to respond to any tapping action (or tapping signal). This allows the vehicle to enter an anti-accidental touch mode, in which the acquired tapping signal is not processed, which helps reduce the vehicle's computational overhead and thus helps avoid wasting the vehicle's power consumption.

[0029] In some possible implementations, when the characteristic parameters of the first tapping signal satisfy the preset condition and the first sensing data indicates that there are no people within the preset range for a cumulative duration greater than or equal to the first preset duration, the tapping signal is ignored within the second preset duration. This includes: when the characteristic parameters of the first tapping signal are detected to satisfy the preset condition and the first sensing data indicates that there are no people within the preset range for a cumulative duration greater than or equal to the first preset duration within the fourth preset duration, the tapping signal is ignored within the second preset duration, wherein the fourth preset duration is greater than the first preset duration.

[0030] In some possible implementations, the cumulative duration during which the characteristic parameters of the first tapping signal satisfy the preset condition and the first sensing data indicates that there are no people within the preset range is greater than or equal to the first preset duration includes: the cumulative number of times the characteristic parameters of the first tapping signal satisfy the preset condition and the first sensing data indicates that there are no people within the preset range is greater than or equal to the first preset number.

[0031] In conjunction with the first aspect, in some implementations of the first aspect, the method further includes: when an input from a user to open the cover is received within the second preset time period via a vehicle infotainment system, a button in the cabin, or a mobile terminal, the method controls the cover to open.

[0032] Based on the above technical solution, if the vehicle receives input from the user to open the cover via the vehicle's infotainment system, a button in the cabin, or a mobile terminal within the second preset time period, the vehicle can respond to the input and execute the cover opening operation. Thus, during the anti-accidental touch mode operation, the user can also perform the cover opening operation through other means.

[0033] In some possible implementations, obtaining the user's input to open the cover via the vehicle's infotainment system includes: obtaining the user's voice command, which is used to instruct the user to open the cover.

[0034] In some possible implementations, the input from the user to open the cover via a button in the cockpit can be obtained, including: the input from the user to open the cover via a virtual button, physical button, or handle in the cockpit.

[0035] In some possible implementations, the user's input to open the cover via a mobile terminal is obtained, including: obtaining the user's input to open the cover via a mobile phone, wearable device (e.g., watch), or car key.

[0036] In conjunction with the first aspect, in some implementations of the first aspect, the method further includes: when controlling the opening of the cover, acquiring a second knocking signal and second sensing data when acquiring the second knocking signal, the second sensing data being used to determine whether there are personnel within a preset range outside the cockpit; and controlling the cover based on the second knocking signal and the second sensing data.

[0037] Based on the above technical solution, if the user performs the operation of opening the cover by other means during the operation of the anti-accidental touch mode, the vehicle can exit the anti-accidental touch mode in a timely manner.

[0038] In conjunction with the first aspect, in some implementations of the first aspect, controlling the cover plate based on the first tapping signal and the first sensing data includes: when the characteristic parameters of the first tapping signal meet preset conditions and the first sensing data indicates that there are no personnel within the preset range, acquiring environmental information of the vehicle's location; modifying the preset characteristic parameters that trigger the opening of the cover plate based on the environmental information; and controlling the cover plate based on the modified preset characteristic parameters and the acquired tapping signal.

[0039] Based on the above technical solution, when there are no people within the preset range and the tapping signal meets the preset conditions, the preset characteristic parameters for triggering the cover to open can be corrected based on the environmental information of the vehicle's location. This reduces the probability of the cover opening accidentally due to objects such as raindrops, hail, or tree branches striking it, thus improving the vehicle's intelligence and enhancing the user experience.

[0040] In some possible implementations, the preset characteristic parameters include one or more of the preset amplitude, preset frequency, preset phase, and preset duration.

[0041] In some possible implementations, the preset characteristic parameters that trigger the opening of the cover are modified according to the environmental information, including: according to the environmental information, performing one or more of the following adjustments: increasing the preset amplitude, increasing the preset frequency, decreasing the preset phase, or increasing the preset duration.

[0042] In conjunction with the first aspect, in some implementations of the first aspect, controlling the cover plate based on the first tapping signal and the first sensing data includes: acquiring environmental information about the vehicle's location when the characteristic parameters of the first tapping signal meet the preset condition and the first sensing data indicates that there are no personnel within the preset range; processing the acquired tapping signal based on the environmental information; and controlling the cover plate based on the preset characteristic parameters and the processed tapping signal.

[0043] Based on the above technical solution, when there are no people within the preset range and the knocking signal meets the preset conditions, the characteristic parameters of the acquired knocking signal can be processed based on the environmental information of the vehicle's location. In this way, by processing the knocking signal, the probability of the cover being accidentally opened due to objects such as raindrops, hail, or tree branches striking the cover can be avoided, which helps to improve the vehicle's intelligence and enhance the user experience.

[0044] In some possible implementations, the acquired tapping signal is processed based on the environmental information, including performing one or more of the following processes: reducing the amplitude of the tapping signal, reducing the frequency of the tapping signal, increasing the phase of the tapping signal, or reducing the tapping duration of the tapping signal.

[0045] By performing one or more of the above processes, the probability of the cover being accidentally opened due to objects such as raindrops, hail, or tree branches hitting the cover can be reduced, which helps to improve the vehicle's intelligence and enhance the user experience.

[0046] In conjunction with the first aspect, in some implementations of the first aspect, controlling the cover based on the first tapping signal and the first sensing data includes: when the characteristic parameters of the first tapping signal meet preset conditions and the first sensing data indicates that there are no personnel within the preset range, acquiring environmental information of the vehicle's location; based on the environmental information, correcting the preset characteristic parameters that trigger the opening of the cover and processing the acquired tapping signal; and controlling the cover based on the corrected preset characteristic parameters and the processed tapping signal.

[0048] Based on the above technical solution, the environmental information of the current location can be determined based on the characteristic parameters of the tapping signal obtained within a third preset time period and the corresponding tapping duration. This helps to improve the accuracy of environmental information.

[0049] In some possible implementations, the environmental information is obtained based on the characteristic parameters of the tapping signals obtained within a third preset time period and the tapping duration corresponding to the tapping signals obtained within the third preset time period. This includes: determining the environmental information based on the number of tapping signals that satisfy the preset characteristic parameters within the third preset time period, or based on the tapping duration corresponding to the tapping signals that satisfy the preset characteristic parameters within the third preset time period.

[0050] In some possible implementations, the characteristic parameters of the striking signal acquired within the third preset time period include one or more of the amplitude, frequency, phase, or duration of the striking signal acquired within the third preset time period.

[0051] In some possible implementations, the environmental information is obtained based on the characteristic parameters of the tapping signals acquired within a third preset time period and the tapping duration corresponding to the tapping signals acquired within the third preset time period, including: determining the environmental information based on the number of tapping signals in the tapping signals acquired within the third preset time period whose waveforms conform to a preset waveform.

[0052] Secondly, a control method is provided, the method comprising: acquiring environmental information of the vehicle's location; correcting a preset characteristic parameter for triggering the opening of a cover based on the environmental information; and controlling the cover, which is located outside the vehicle's cabin, based on the corrected preset characteristic parameter and the acquired knocking signal.

[0053] Based on the above technical solution, by processing the knocking signal, the probability of the cover being opened accidentally due to objects such as raindrops, hail or tree branches hitting the cover can be avoided, which helps to improve the intelligence of the vehicle and also helps to improve the user experience.

[0054] Taking the hood as an example, based on the above technical solution, it can avoid property loss for users and the safety hazards caused by the hood being accidentally triggered to open when encountering the above scenarios during driving, thus helping to improve the driving safety of users.

[0057] Based on the above technical solution, environmental information can be obtained by combining data collected by the rain sensor on the windshield. This allows the vehicle to use existing sensors to determine environmental information, avoiding the need for additional hardware or software to acquire it. This also reduces the probability of the cover opening accidentally due to raindrops, hail, or tree branches hitting it, thus lowering vehicle costs.

This allows the use of existing sensors in the vehicle to determine the environmental information, avoiding the need for additional hardware or software when acquiring environmental information. This also reduces the probability of the cover being accidentally opened due to objects such as raindrops, hail, or tree branches hitting the cover, and lowers the cost of the vehicle.

[0103] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B; "and / or" in this document is merely a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. "At least one" refers to one or more. For example, "at least one of A and B," similar to "A and / or B," describes the association relationship between related objects, indicating that three relationships can exist. For example, at least one of A and B can represent: A existing alone, A and B existing simultaneously, and B existing alone.

[0104] The prefixes such as "first" and "second" used in this application embodiment are merely for distinguishing different descriptive objects and do not limit the position, order, priority, quantity, or content of the described objects. The use of ordinal numbers and other prefixes used to distinguish descriptive objects in this application embodiment does not constitute a limitation on the described objects. The description of the described objects is given in the claims or the context of the embodiments, and should not constitute unnecessary restrictions due to the use of such prefixes. Furthermore, in the description of this embodiment, unless otherwise stated, "multiple" means two or more.

[0105] Figure 1 This is a functional block diagram of the vehicle 100 provided in the embodiments of this application.

[0106] like Figure 1As shown, vehicle 100 may include a perception system 110, a computing platform 120, and a cover 130. The perception system 110 may include one or more sensors for sensing information about the environment surrounding vehicle 100. For example, the perception system 110 may include a positioning system, which may be a Global Positioning System (GPS), a BeiDou Navigation Satellite System, or another positioning system. As another example, the perception system 110 may include one or more of the following: an inertial measurement unit (IMU), an accelerometer, a lidar, millimeter-wave radar, ultrasonic radar, and a camera device. As yet another example, the perception system 110 may include one or more collision sensors.

[0107] Some or all of the functions of vehicle 100 can be controlled by computing platform 120. Computing platform 120 may include one or more processors, such as processors 121 to 12n (n being a positive integer). A processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a central processing unit (CPU), microprocessor, graphics processing unit (GPU) (which can be understood as a type of microprocessor), or digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. These logical relationships are fixed or reconfigurable. For example, the processor may be a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as a field-programmable gate array (FPGA). In reconfigurable hardware circuits, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement some or all of the functions of the aforementioned units. Furthermore, the processor can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), tensor processing unit (TPU), deep learning processing unit (DPU), etc. In addition, the computing platform 120 may also include a memory for storing instructions. Some or all of the processors 121 to 12n can call the instructions in the memory to implement the corresponding functions.

[0108] The cover 130 may include, but is not limited to, a cover with a knock-open function located outside the cabin, such as a front hood, fuel filler cap, charging port cap, or door (e.g., side door or tailgate).

[0109] Optionally, the structure of the vehicle 100 described above is merely illustrative. In actual applications, various components of the vehicle 100 may be added or removed as needed.

[0110] The vehicle 100 in this application may include: road vehicles, water vehicles, air vehicles, industrial equipment, agricultural equipment, or entertainment equipment, etc. For example, vehicle 100 may be a means of transportation (such as commercial vehicles, passenger cars, motorcycles, flying cars, trains, etc.), industrial vehicles (such as forklifts, trailers, tractors, etc.), engineering vehicles (such as excavators, bulldozers, cranes, etc.), agricultural equipment (such as lawnmowers, harvesters, etc.), amusement equipment, toy vehicles, etc. The embodiments of this application do not specifically limit the type of vehicle.

[0111] As mentioned earlier, some vehicles are now equipped with a knock-to-open hood function, which triggers the hood to open when the user knocks on it. However, due to the vehicle's environment, there is a certain probability that the hood will be accidentally opened in certain scenarios (such as rain, snow, hail, falling branches, or other objects falling onto the hood), resulting in a poor user experience.

[0112] This application provides a control method, device, and vehicle that helps reduce the probability of accidental triggering of cover panels with knock-open functions on certain external configurations, thereby improving the user's driving experience.

[0113] Figure 2 A schematic flowchart of a control method 200 provided in an embodiment of this application is shown. The method 200 includes:

[0114] S210, acquire a first tapping signal and first sensing data when the first tapping signal is acquired, the first sensing data being used to determine whether there are personnel within a preset range outside the cockpit.

[0115] Optionally, the first sensor data may be data collected by one or more of a camera, ultrasonic radar, lidar, or millimeter-wave radar outside the vehicle cabin.

[0116] Optionally, the impact signal is a signal collected by an elastic wave sensor located near the cover plate.

[0117] The striking signal in the embodiments of this application can also be referred to as an elastic wave signal.

[0118] Optionally, the cover can be a hood, fuel filler cap, charging port cap, side door, or tailgate. The vehicle can be equipped with a tap-to-open function for the cover, such as a double-tap function.

[0119] Optionally, acquiring the first tapping signal and the first sensing data when acquiring the first tapping signal includes: acquiring the first sensing data when the characteristic parameters of the first tapping signal meet preset conditions.

[0120] For example, the characteristic parameters of the first striking signal include at least one of the amplitude, frequency, phase and duration of the first striking signal.

[0121] Figure 3 The diagram illustrates the curves showing the amplitude of a tapping signal generated by a finger tapping a cover plate over time, and the amplitude of a tapping signal generated by raindrops falling on the cover plate over time, according to embodiments of this application. Figure 3 As can be seen, the amplitude of the tapping signal generated by a finger hitting the cover plate is greater than that generated by raindrops falling on the cover plate.

[0122] Optionally, acquiring the first sensing data at the time of the first tapping signal includes: acquiring sensing data collected within a period of time before the first tapping signal; or, acquiring sensing data collected at the time of the first tapping signal; or, acquiring sensing data collected within a period of time after the first tapping signal.

[0123] For example, if the first tap signal is acquired within the time period [T1, T1+0.5s], then the first sensing data can be the sensing data acquired by the sensor outside the cockpit within the time period [T1, T1+0.5s]; or, the first sensing data can be the sensing data acquired by the sensor outside the cockpit within the time period [T1-0.5s, T1]; or, the first sensing data can be the sensing data acquired by the sensor outside the cockpit within the time period [T1+0.5s, T1+1s].

[0124] S220, based on the first tapping signal and the first sensor data, controls the cover, which is located outside the cockpit.

[0125] Optionally, controlling the cover plate according to the first tapping signal and the first sensing data includes: controlling the cover plate to open when the characteristic parameters of the first tapping signal meet preset conditions and the first sensing data indicates that there are personnel within the preset range.

[0126] In this embodiment, the cover can be opened when there are people within a preset range and the tapping signal meets preset conditions. This improves the accuracy of cover opening in certain scenarios (e.g., rain, snow, hail, falling branches, or other objects falling onto the cover), avoids the cumbersome operation of the user getting out of the vehicle to close the cover after accidental opening, helps improve the vehicle's intelligence level, and also helps improve the user experience.

[0127] Taking the hood as an example, the embodiments of this application can avoid property damage to users and the safety hazards caused by the hood being accidentally triggered to open when encountering the above-mentioned scenarios during driving, which helps to improve the driving safety of users.

[0128] Optionally, the characteristic parameters of the first striking signal satisfy preset conditions, including: the characteristic parameters of the first striking signal satisfy preset characteristic parameters.

[0129] For example, the characteristic parameters of the first striking signal satisfy preset characteristic parameters, including the first striking signal satisfying one or more of the following conditions:

[0130] (1) The amplitude of the first tap signal is greater than or equal to the preset amplitude;

[0131] (2) The frequency of the first tapping signal is greater than or equal to the preset frequency;

[0132] (3) The phase of the first striking signal is less than or equal to the preset phase;

[0133] (4) The duration of the first tap signal is greater than or equal to the preset tap duration.

[0134] The preset feature parameters mentioned above may include one or more of the following: preset amplitude, preset frequency, preset phase, or preset tapping duration.

[0135] Optionally, before controlling the opening of the cover, the method 200 further includes: obtaining, based on the first sensing data, the action of the person knocking on the cover.

[0136] For example, consider an image captured by a camera outside the cockpit as the first sensing data. When the characteristic parameters of the first tapping signal satisfy preset characteristic parameters, the first image captured by the camera outside the cockpit can be acquired. If the first image includes a person and the input of the person tapping the cover is detected based on the first image, then it can be determined that the person performed the action of tapping the cover.

[0137] In this embodiment, the cover can be opened when a person performs a tapping action on the cover within a preset range and the tapping signal meets preset conditions. This further improves the accuracy of controlling the cover opening in certain scenarios, avoids the cumbersome operation of the user getting out of the vehicle to close the cover after accidental opening, helps improve the vehicle's intelligence level, and also helps improve the user experience.

[0138] Optionally, before controlling the opening of the cover, the method 200 further includes: determining that the person's biometric information matches the biometric information stored in the vehicle.

[0139] For example, consider an image captured by a camera outside the cockpit as the first sensing data. When the characteristic parameters of the first tapping signal meet preset characteristic parameters, the first image captured by the camera outside the cockpit can be acquired. If the first image includes a person, and the input of the person tapping the cover is detected based on the first image, and the biometric information of the person identified based on the image matches the biometric information of one or more users stored in the vehicle, the cover can be controlled to open.

[0140] For example, before determining that the person's biometric information matches the biometric information stored in the vehicle, the method includes: acquiring an image within a preset range; determining that the person's biometric information matches the biometric information stored in the vehicle includes: determining that the facial features in the image match the facial features of one or more users stored in the vehicle.

[0141] For example, before determining that the biometric information of the person matches the biometric information stored in the vehicle, the method includes: acquiring the voiceprint information of the person within the preset range; determining that the biometric information of the person matches the biometric information stored in the vehicle includes: determining that the facial features in the voiceprint information match the voiceprint features of one or more users stored in the vehicle.

[0142] It should be noted that the information collected by the camera or microphone in this embodiment is only used to determine whether the person has the authority to open the cover. Before collecting the information by the camera or microphone, the user can be prompted to authorize, and the above operation can be performed after the user authorizes. The acquisition of this information complies with the relevant laws and regulations of the relevant countries and regions.

[0143] In this embodiment, when a person matching the biometric information stored in the vehicle performs a tapping action on the cover within a preset range, and the tapping signal meets preset conditions, the cover can be controlled to open. This further improves the accuracy of controlling the cover opening in certain scenarios, avoids the cumbersome operation of the user getting out of the vehicle to close the cover after accidental opening, helps improve the vehicle's intelligence level, and also enhances the user experience.

[0144] Optionally, controlling the cover plate according to the first tapping signal and the first sensing data includes: controlling the cover plate to remain closed when the characteristic parameters of the first tapping signal meet preset conditions and the first sensing data indicates that there are no personnel within the preset range.

[0145] In this embodiment, the cover can be kept closed when there are no people within a preset range and the tapping signal meets preset conditions. This reduces the probability of the cover being accidentally opened in certain scenarios, avoids the cumbersome operation of the user getting out of the vehicle to close the cover after it has been accidentally opened, helps improve the vehicle's intelligence level, and also helps improve the user experience.

[0146] Optionally, controlling the cover plate based on the first tapping signal and the first sensing data includes: controlling the cover plate to remain closed when the characteristic parameters of the first tapping signal do not meet preset conditions.

[0147] Optionally, the characteristic parameters of the first tapping signal do not meet the preset conditions, including: the characteristic parameters of the first tapping signal do not meet the characteristic parameters of the tapping signal generated by the user's finger tapping the cover plate.

[0148] Optionally, the method 200 further includes: when the characteristic parameters of the first tapping signal meet the preset condition and the first sensing data indicates that there is no person within the preset range for a cumulative duration greater than or equal to the first preset duration, the acquired tapping signal is ignored within the second preset duration.

[0149] For example, the first preset duration is 7.5 seconds.

[0150] For example, the second preset duration is 60 seconds.

[0151] In this embodiment, after the characteristic parameters of the tapping signal meet the preset condition and the cumulative duration of no personnel within the preset range is greater than or equal to the first preset duration, the vehicle can ignore the acquired tapping signal within a second preset duration. Alternatively, the vehicle can control the cover not to respond to any tapping action (or tapping signal). This allows the vehicle to enter an anti-accidental touch mode, in which the acquired tapping signal is not processed, which helps reduce the vehicle's computational overhead and thus helps avoid wasting the vehicle's power consumption.

[0152] Optionally, when the characteristic parameters of the first tapping signal satisfy the preset condition and the cumulative duration of the first sensing data indicating that there are no people within the preset range is greater than or equal to the first preset duration, the tapping signal is ignored within the second preset duration, including: when the characteristic parameters of the first tapping signal are detected to satisfy the preset condition and the cumulative duration of the first sensing data indicating that there are no people within the preset range is greater than or equal to the first preset duration within the fourth preset duration, the tapping signal is ignored within the second preset duration, wherein the fourth preset duration is greater than the first preset duration.

[0153] For example, the fourth preset duration is 60 seconds.

[0154] For example, taking the hood as an example, the first tapping signal can be a tapping signal acquired within 60 seconds. Detection can be performed in 0.5-second cycles. If two tapping signals are detected within one detection cycle, and the characteristic parameters of the two tapping signals meet preset characteristic parameters, and there is no user within 1 meter in front of the vehicle, then this detection cycle can be included in the cumulative duration of accidental touches. If the cumulative duration of accidental touches within 60 seconds is greater than or equal to 7.5 seconds, then the vehicle will ignore the acquired tapping signals for the next 60 seconds.

[0155] Optionally, the cumulative duration during which the characteristic parameters of the first tapping signal satisfy the preset condition and the first sensing data indicates that there are no people within the preset range is greater than or equal to the first preset duration includes: the cumulative number of times the characteristic parameters of the first tapping signal satisfy the preset condition and the first sensing data indicates that there are no people within the preset range is greater than or equal to the first preset number.

[0156] For example, taking the hood as an example, the first tapping signal can be a tapping signal acquired within 60 seconds. Detection can be performed in 0.5-second cycles. If two tapping signals are detected within one detection cycle, and the characteristic parameters of the two tapping signals meet preset characteristic parameters, and there is no user within 1 meter in front of the vehicle, then this detection cycle corresponds to one false touch count. If the number of false touch counts within 60 seconds is greater than or equal to 15, then the vehicle ignores the acquired tapping signals for the next 60 seconds.

[0157] The above vehicles will ignore the received tapping signals for the next 60 seconds, which can be understood as the vehicle entering the anti-accidental touch mode for the next 60 seconds.

[0158] Optionally, the method 200 further includes: when an input from a user to open the cover is received within the second preset time period via the vehicle system, a button in the cabin, or a mobile terminal, the cover is controlled to open.

[0159] For example, obtaining input from the user to open the cover via the vehicle's infotainment system includes: obtaining the user's voice command, which is used to instruct the user to open the cover.

[0160] For example, obtaining input from the user to open the cover via a button in the cockpit includes: obtaining input from the user to open the cover via a virtual button, physical button, or handle in the cockpit.

[0161] For example, obtaining input from a user to open the cover via a mobile terminal includes obtaining input from a user to open the cover via a mobile phone, wearable device (e.g., watch), or car key.

[0162] In this embodiment, if the vehicle receives input from a user to open the cover via the vehicle's infotainment system, a button in the cabin, or a mobile terminal within a second preset time period, the vehicle can respond to the input and perform the cover opening operation. Thus, during the anti-accidental touch mode operation, the user can also perform the cover opening operation through other means.

[0163] Optionally, the method 200 further includes: when controlling the opening of the cover, acquiring a second knocking signal and second sensing data when acquiring the second knocking signal, the second sensing data being used to determine whether there are personnel within a preset range outside the cockpit; and controlling the cover according to the second knocking signal and the second sensing data.

[0164] In this embodiment of the application, if the user performs the operation of opening the cover by other means during the operation of the anti-accidental touch mode, the vehicle can exit the anti-accidental touch mode in a timely manner.

[0165] Optionally, controlling the cover based on the first tapping signal and the first sensing data includes: when the characteristic parameters of the first tapping signal meet preset conditions and the first sensing data indicates that there are no personnel within the preset range, acquiring environmental information of the vehicle's location; correcting the preset characteristic parameters that trigger the opening of the cover based on the environmental information; and controlling the cover based on the corrected preset characteristic parameters and the acquired tapping signal.

[0166] Optionally, the preset characteristic parameters include one or more of the preset amplitude, preset frequency, preset phase, and preset duration.

[0167] Optionally, based on the environmental information, the preset characteristic parameters that trigger the opening of the cover are modified, including: based on the environmental information, performing one or more of the following adjustments: increasing the preset amplitude, increasing the preset frequency, decreasing the preset phase, or increasing the preset duration.

[0168] For example, before correcting the preset characteristic parameters that trigger the opening of the cover, the preset characteristic parameters include one or more of the preset amplitude 1, preset frequency 1, preset phase 1, and preset duration 1. After correcting the preset characteristic parameters that trigger the opening of the cover, the preset amplitude is corrected from preset amplitude 1 to preset amplitude 2, the preset frequency is corrected from preset frequency 1 to preset frequency 2, the preset phase is corrected from preset phase 1 to preset phase 2, and the preset duration is corrected from preset duration 1 to preset duration 2; wherein, the preset amplitude 2 is greater than the preset amplitude 1, the preset frequency 2 is greater than the preset frequency 1, the preset phase 2 is less than the preset phase 1, and the preset duration 2 is greater than the preset duration 1.

[0169] In this embodiment, when there are no people within a preset range and the tapping signal meets preset conditions, the preset characteristic parameters triggering the opening of the cover can be corrected based on the environmental information of the vehicle's location. This reduces the probability of the cover being accidentally opened due to objects such as raindrops, hail, or tree branches hitting the cover, which helps improve the vehicle's intelligence and enhances the user experience.

[0170] Optionally, controlling the cover plate according to the first tapping signal and the first sensing data includes: acquiring environmental information of the vehicle's location when the characteristic parameters of the first tapping signal meet the preset condition and the first sensing data indicates that there are no personnel within the preset range; processing the acquired tapping signal according to the environmental information; and controlling the cover plate according to the preset characteristic parameters and the processed tapping signal.

[0171] Optionally, based on the environmental information, the acquired tapping signal is processed, including performing one or more of the following processes: reducing the amplitude of the tapping signal, reducing the frequency of the tapping signal, increasing the phase of the tapping signal, or reducing the tapping duration of the tapping signal.

[0172] In this embodiment, when there are no people within a preset range and the knocking signal meets preset conditions, the characteristic parameters of the acquired knocking signal can be processed based on the environmental information of the vehicle's location. By processing the knocking signal, the probability of the cover being accidentally opened due to objects such as raindrops, hail, or tree branches striking the cover can be avoided, which helps improve the vehicle's intelligence and enhances the user experience.

[0173] By performing one or more of the above processes, the probability of the cover being accidentally opened due to objects such as raindrops, hail, or tree branches hitting the cover can be reduced, which helps to improve the vehicle's intelligence and enhance the user experience.

[0174] Optionally, controlling the cover based on the first tapping signal and the first sensing data includes: acquiring environmental information about the vehicle's location when the characteristic parameters of the first tapping signal meet preset conditions and the first sensing data indicates that there are no personnel within the preset range; correcting the preset characteristic parameters that trigger the opening of the cover based on the environmental information and processing the acquired tapping signal; and controlling the cover based on the corrected preset characteristic parameters and the processed tapping signal.

[0175] Optionally, obtaining environmental information about the vehicle's location includes: obtaining the environmental information based on the characteristic parameters of the tapping signal obtained within a third preset time period and the tapping duration corresponding to the tapping signal obtained within the third preset time period.

[0176] For example, the characteristic parameters of the striking signal obtained within the third preset time period include one or more of the amplitude, frequency, phase, or duration of the striking signal obtained within the third preset time period.

[0177] Optionally, the environmental information is obtained based on the characteristic parameters of the tapping signals obtained within a third preset time period and the tapping duration corresponding to the tapping signals obtained within the third preset time period, including: determining the environmental information based on the number of tapping signals that satisfy the preset characteristic parameters within the third preset time period, or based on the tapping duration corresponding to the tapping signals that satisfy the preset characteristic parameters within the third preset time period.

[0178] Optionally, the characteristic parameters of the striking signal acquired within the third preset time period include one or more of the amplitude, frequency, phase, or duration of the striking signal acquired within the third preset time period.

[0179] Optionally, the environmental information is obtained based on the characteristic parameters of the tapping signals acquired within a third preset time period and the corresponding tapping duration of the tapping signals acquired within the third preset time period. This includes determining the environmental information based on the number of tapping signals among the tapping signals acquired within the third preset time period whose waveforms conform to a preset waveform. For example, the tapping duration corresponding to the tapping signals acquired within the third preset time period can be determined by the number of tapping signals among the tapping signals acquired within the third preset time period whose waveforms conform to a preset waveform.

[0180] In this embodiment of the application, the environmental information of the current location can be determined based on the characteristic parameters of the tapping signal obtained within a third preset time period and the tapping duration corresponding to the tapping signal.

[0181] For example, the impact signal collected by the elastic wave sensor is continuously detected with a detection cycle of 0.5 seconds, and the result is judged every 30 seconds. If the characteristic parameters of the impact signal detected in 16 detection cycles within these 60 detection cycles meet the characteristic parameters of the impact signal generated by raindrops falling on the cover plate, it can be determined that the current situation is a light rain scenario; if the characteristic parameters of the impact signal detected in 32 detection cycles within these 60 detection cycles meet the characteristic parameters of the impact signal generated by raindrops falling on the cover plate, it can be determined that the current situation is a moderate rain scenario; if the characteristic parameters of the impact signal detected in 48 detection cycles within these 60 detection cycles meet the characteristic parameters of the impact signal generated by raindrops falling on the cover plate, it can be determined that the current situation is a heavy rain scenario.

[0182] If the scene is determined to be light rain, the tapping force coefficient is the light rain coefficient; if the scene is determined to be moderate rain, the tapping force coefficient is the moderate rain coefficient; if the scene is determined to be heavy rain, the tapping force coefficient is the heavy rain coefficient.

[0183] For example, the above light rain coefficient, moderate rain coefficient, and heavy rain coefficient may include one or more sub-coefficients. Taking a vehicle in a light rain scenario and the preset feature parameters being corrected as an example, if the preset feature parameters include a preset amplitude and a preset phase, then the light rain coefficient may include coefficient A and coefficient B. Coefficient A is a correction coefficient for the preset amplitude and is greater than 1, while coefficient B is a correction coefficient for the preset phase and is greater than 0 and less than 1. The corrected preset amplitude can be the original preset amplitude multiplied by coefficient A, and the corrected preset phase can be the original preset phase multiplied by coefficient B.

[0184] If the characteristic parameters of the knocking signal detected within 30 seconds meet the characteristic parameters of the knocking signal generated by raindrops falling on the cover plate and the knocking duration is less than or equal to 4 seconds, then it can be determined that the rain has ended and the knocking force coefficient can be restored to the knocking force coefficient before correction.

[0185] Figure 4 A schematic flowchart of a method 400 for modifying preset feature parameters provided in an embodiment of this application is shown. The method 400 includes:

[0186] S401 detects the tapping signal according to the detection cycle.

[0187] For example, the detection cycle is 0.5s.

[0188] S402, determine whether the tapping signal in each detection cycle meets the preset characteristic parameters.

[0189] If the characteristic parameters of the knocking signal detected in a certain detection cycle do not meet the characteristic parameters of the knocking signal generated by raindrops falling on the cover plate, then proceed to the next detection cycle for detection; otherwise, execute S403.

[0190] S403, if the characteristic parameters of the knocking signal detected in a certain detection cycle meet the characteristic parameters of the knocking signal generated by raindrops falling on the cover plate, then this detection cycle is recorded as a raindrop knocking.

[0191] S404, determine whether the preset duration has been reached.

[0192] For example, the preset duration is 30 seconds.

[0193] If the preset time is reached, execute S405; otherwise, return to continue executing S401.

[0194] S405, determine whether the cumulative number of raindrop impacts is greater than the preset value A.

[0195] For example, the preset value A is 48 times.

[0196] If the value is greater than the preset value A, then S406 can be executed; if the value is less than or equal to the preset value A, then S407 can be executed.

[0197] S406, the correction factor is determined to be the heavy rain factor.

[0198] S407, determine whether the cumulative number of raindrop impacts is greater than the preset value B.

[0199] For example, the preset value B is less than the preset value A.

[0200] For example, the default value B is 32.

[0201] If the value is greater than the preset value B, then S408 can be executed; if the value is less than or equal to the preset value A, then S409 can be executed.

[0202] S408, the correction factor is determined to be the moderate rain factor.

[0203] S409, determine whether the cumulative number of raindrop impacts is greater than the preset value C.

[0204] For example, the preset value C is less than the preset value B.

[0205] For example, the default value C is 16.

[0206] If the value is greater than the preset value C, then S410 can be executed; if the value is less than or equal to the preset value A, then S411 can be executed.

[0207] S410, the correction factor is determined to be the light rain factor.

[0208] S411, No correction is made to the preset feature parameters.

[0209] For example, in this embodiment of the application, a sliding window detection method can be used to determine the rain scene.

[0210] For example, the cumulative number of raindrop impacts can be counted within [T0, T0+30s]. If the cumulative number of impacts is greater than a preset value A, it can be determined as a heavy rain scene. In this way, the heavy rain coefficient can be used to correct the preset feature parameters and obtain the corrected preset feature parameters.

[0211] For example, the cumulative number of raindrop impacts can be counted within [T0+1s, T0+31s]. If the cumulative number of impacts is greater than the preset value A, the corrected feature parameters can be maintained.

[0212] For example, the cumulative number of raindrop taps can be counted within [T0+2s, T0+32s]. If the cumulative number of taps is less than or equal to the preset value C, the preset feature parameters can be restored.

[0213] Figure 5 A schematic flowchart of a control method 500 provided in an embodiment of this application is shown. Figure 5 As shown, the method 500 includes:

[0214] S501, acquires the tap signal.

[0215] S502, determine whether the characteristic parameters of the tapping signal meet the characteristic parameters of the tapping signal generated by a finger tapping the cover plate.

[0216] For example, if the characteristic parameters of the tapping signal satisfy the characteristic parameters of the tapping signal generated by a finger tapping the cover plate, then S503 is executed; otherwise, S504 is executed.

[0217] S503 determines whether there are personnel within a preset range outside the cockpit.

[0218] If there are personnel within the preset range, execute S505; otherwise, execute S506.

[0219] S504, ignore the knock signal.

[0220] S505 controls the opening of the cover.

[0221] For example, if the knocking signal determines that two valid knocking actions are detected within 0.5 seconds and there are people within 1 meter in front of the vehicle, then the hood can be opened.

[0222] S506, update the number of accidental touches.

[0223] For example, if the knocking signal determines that two valid knocking actions are detected within 0.5 seconds and there are people within 1 meter in front of the vehicle, the number of false touches is incremented by 1.

[0224] S507, determine whether the number of accidental touches is greater than the preset number.

[0225] For example, the preset number of times is 15.

[0226] If the number of accidental touches exceeds the preset number, then S508 can be executed; otherwise, return to continue executing S501.

[0227] S508 controls the vehicle to enter the anti-accidental touch mode.

[0228] For example, the duration of this anti-accidental touch mode is 60 seconds.

[0229] When the duration of the anti-accidental touch mode ends, S501 can continue to be executed.

[0230] Optionally, when the vehicle is in the anti-mistouch mode and a user is detected to trigger an input to open the cover via the vehicle's infotainment system, a button in the cabin, or a mobile terminal, the anti-mistouch mode can be exited and S501 can continue to be executed.

[0231] Figure 6 A schematic block diagram of a control method 600 provided in an embodiment of this application is shown. The method 600 includes:

[0232] S610 obtains environmental information about the vehicle's location.

[0233] Optionally, obtaining environmental information about the vehicle's location includes: obtaining the environmental information based on the characteristic parameters of the tapping signal obtained within a third preset time period and the tapping duration corresponding to the tapping signal obtained within the third preset time period.

[0234] The environmental information obtained based on the characteristic parameters of the tapping signal acquired within the third preset time period and the corresponding tapping duration of the tapping signal acquired within the third preset time period can be referred to the description in method 200, which will not be repeated here.

[0235] Optionally, obtaining environmental information about the vehicle's location includes: obtaining the environmental information based on data collected by a rain sensor on the windshield.

[0236] For example, the rain sensor can be an infrared sensor.

[0237] In this embodiment, environmental information can be obtained by combining data collected from a rain sensor on the windshield. This allows the use of existing sensors in the vehicle to determine environmental information, avoiding the need for additional hardware or software to acquire it. This also reduces the probability of the cover opening accidentally due to raindrops, hail, or tree branches hitting it, thus lowering vehicle costs.

[0238] Optionally, obtaining the environmental information of the vehicle's location includes: obtaining the environmental information based on the weather information of the vehicle's location indicated in the weather application.

[0239] In this embodiment, the environmental information can be obtained by combining the weather information indicated in the weather application. This allows the use of existing sensors in the vehicle to determine the environmental information, avoiding the need for additional hardware or software when acquiring environmental information. This also reduces the probability of the cover being accidentally opened due to objects such as raindrops, hail, or tree branches hitting the cover, and lowers the cost of the vehicle.

[0240] S620, based on the environmental information, corrects the preset characteristic parameters that trigger the opening of the cover, which is located outside the vehicle's cabin.

[0241] The process of correcting the preset feature parameters described above can be referred to the description in method 200 above, and will not be repeated here.

[0242] S630 controls the cover plate based on the corrected preset characteristic parameters and the acquired tapping signal.

[0243] In this embodiment of the application, by processing the tapping signal, the probability of the cover being accidentally opened due to objects such as raindrops, hail or tree branches hitting the cover can be avoided, which helps to improve the intelligence of the vehicle and also helps to improve the user experience.

[0244] Figure 7 A schematic flowchart of a control method 700 provided in an embodiment of this application is shown. The method 700 includes:

[0245] S710 obtains environmental information about the vehicle's location.

[0246] Optionally, obtaining environmental information about the vehicle's location includes: obtaining the environmental information based on the characteristic parameters of the tapping signal obtained within a third preset time period and the tapping duration corresponding to the tapping signal obtained within the third preset time period.

[0247] The environmental information obtained based on the characteristic parameters of the tapping signal acquired within the third preset time period and the corresponding tapping duration of the tapping signal acquired within the third preset time period can be referred to the description in method 200, which will not be repeated here.

[0251] The processing of the acquired tapping signals can be referred to the description in method 200 above, and will not be repeated here.

[0252] S730 controls the cover, located outside the vehicle's cabin, based on preset characteristic parameters and the processed knocking signal.

[0253] Methods 200, 400, 500, 600, and 700 can be executed by the vehicle 100; or, methods 200, 400, 500, 600, and 700 can be executed by the computing platform 120; or, methods 200, 400, 500, 600, and 700 can be executed by the processor, chip, or circuit in the computing platform 120.

[0254] The above methods can be combined with each other. For example, methods 200 and 600 can be combined. For instance, the impact signal collected by the elastic wave sensor is continuously detected in 0.5-second detection cycles, and the result is judged every 30 seconds. If, within these 60 detection cycles, the characteristic parameters of the impact signal detected in 16 detection cycles meet the characteristic parameters of the impact signal generated by raindrops falling on the cover plate, and the data collected by the rain sensor determines that the rainfall at the current vehicle location is the rainfall corresponding to a light rain scenario, then it can be determined that the current situation is a light rain scenario.

[0255] For example, if the characteristic parameters of the knocking signal detected in 16 out of the 60 detection cycles meet the characteristic parameters of the knocking signal generated by raindrops falling on the cover plate, and the data collected by the rain sensor determines that the rainfall at the current location of the vehicle is the rainfall corresponding to a light rain scenario, and the weather information in the weather application indicates that the weather at the current location of the vehicle is light rain, then it can be determined that the current location is in a light rain scenario.
