[0054] In the following text, reference will be made to Figures 1 to 19 The embodiments of this disclosure are described in detail.

[0055] Figure 1 This is a diagram illustrating an embodiment of a vehicle equipped with an ultrasonic generator according to an embodiment of the present disclosure.

[0056] Reference Figure 1 The ultrasonic generator 100 according to an embodiment of the present disclosure can be implemented in a portable form for mounting on a cup holder 95 in a vehicle 1.

[0061] According to an embodiment, the dashboard may include various instrument panels capable of displaying the vehicle 1's driving speed, engine RPM, remaining fuel level, etc., as well as a glove box capable of receiving various items.

[0062] In addition, a USB port 90 for connecting a storage media access device to the AVN device of the vehicle 1 can be installed in the central instrument panel 50 of the instrument panel.

[0063] An AVN device refers to a terminal capable of integrating functions that provide audio and video to a user and navigation functions that provide a user with a route to a destination. An AVN device may display various control screens related to the control of vehicle 1 or screens related to additional functions that can be performed in the AVN device, and may selectively display at least one of an audio screen, a video screen, or a navigation screen on display 51.

[0064] The AVN device can connect to a storage media access device via USB port 90.

[0065] Furthermore, vehicle 1 may include a speaker capable of transmitting multimedia sound sources. The speaker can transmit a predetermined sound source to the user when the ultrasonic generator 100 is operating.

[0066] The sensor device SU can detect mosquitoes in vehicle 1. Furthermore, the sensor device SU can determine the location of the detected mosquitoes. Below, a description of the sensor device SU utilizing an ultrasonic sensor in an embodiment of this disclosure will be given. Therefore, the sensor device SU is referred to as an ultrasonic sensor.

[0067] Figure 1 An embodiment is shown in which the ultrasonic sensor SU is implemented independently of the ultrasonic generator 100, but the ultrasonic sensor SU can be integrally formed with the ultrasonic generator 100.

[0068] Figure 2 This is a diagram illustrating an embodiment of an ultrasonic generator according to an embodiment of the present disclosure. Figure 3 It shows except Figure 2 A diagram showing the structure of the ultrasonic generator other than its cover. Figure 4 This is a diagram showing an exploded perspective view of an ultrasonic generator.

[0069] Reference Figures 2 to 4 , Figure 1 The ultrasonic generator 100 can be implemented as a portable multi-functional machine that can be installed in the cup holder 95 of the vehicle 1, and can include a main body 10 and a cover 20.

[0070] The main body 10 can support the overall configuration of the ultrasonic generator 100 and can provide a mounting surface. Figure 5 The space shown is for the circuit components 160, etc. The main body 10 can be implemented in the form of a cylindrical box so that it can be easily inserted into the cup holder 95.

[0071] User input sections 12, 13, and 16 may be formed on the outer side of the main body 10, for example, at the lower part of the main body 10. User input sections 12, 13, and 16 may be implemented as buttons, and multiple buttons may be formed to control specific operations respectively. For example, user input sections 12, 13, and 16 may include a power button 12 for turning the ultrasonic generator 100 on / off, and a control button 16 for... Figure 4 The rotary selection button 13 for operating the motor 33 and the waveform selection button 16 for controlling the vibration waveform of the ultrasonic wave are shown.

[0072] The cover 20 can be connected to the main body 10, and multiple holes can be formed in the cover 20 so that the transmitting signal generated by the ultrasonic vibrator UT can be transmitted to the outside.

[0073] The power input unit 140 and operation display units 24, 25, and 27 can be formed on the outer side of the cover 20. The power input unit 140 can be a Universal Serial Bus (USB) socket. The operation display units 24, 25, and 27 can display the operating status of the ultrasonic generator 100, and they can be implemented as multiple light-emitting diodes (LEDs). For example, the operation display units 24, 25, and 27 may include a power LED 24 for providing a notification that the power is on, a motor LED 25 for displaying the operating status of the motor 33, and a waveform LED 27 for displaying the ultrasonic vibration status.

[0074] Circuit component 160, amplifier AMP, motor 33, first ultrasonic vibrator UT1 and second ultrasonic vibrator UT2 can be included in cover 20.

[0075] Circuit component 160 can be implemented as a printed circuit board (PCB). An amplifier AMP can be electrically connected to circuit component 160 to amplify the modulated signal generated by circuit component 160.

[0076] The motor 33 can rotate the rotating plate 34 based on the control of the circuit component 160.

[0077] The first ultrasonic vibrator UT1 and the second ultrasonic vibrator UT2 can generate ultrasonic waves based on the amplified signal provided by the amplifier AMP.

[0078] The first ultrasonic vibrator UT1 and the second ultrasonic vibrator UT2 can output ultrasonic waves with different frequencies. The first frequency output by the first ultrasonic vibrator UT1 and the second frequency output by the second ultrasonic vibrator UT2 can be frequencies used to repel mosquitoes. The first ultrasonic vibrator UT1 and the second ultrasonic vibrator UT2 can be connected to a rotating plate 34 to adjust the direction of ultrasonic wave transmission according to the rotation of the rotating plate 34.

[0079] The first ultrasonic vibrator UT1 and the second ultrasonic vibrator UT2 can be classified into magnetostrictive vibrators, piezoelectric vibrators, etc., according to the vibration generation principle.

[0080] Magnetostrictive vibrators can use coils wound around ferrite or other magnetic materials. A magnetostrictive vibrator can generate ultrasonic waves in a direction perpendicular to the magnetic field by resonating with its natural frequency in response to an applied current.

[0081] Piezoelectric vibrators can convert mechanical stress into electrical charge using the piezoelectric effect, thus allowing for simple structures. Piezoelectric materials can generate longitudinal or shear waves depending on the cutting pattern. After polarization, an AC voltage can be applied to the piezoelectric material to induce repeated expansion and contraction. Piezoelectric vibrators can output ultrasonic waves based on the vibration of the piezoelectric material.

[0082] Figure 5 It is a block diagram showing the configuration of the circuit components.

[0083] Reference Figure 5 The circuit component 160 may include a drive signal generator 161, a modulator 162, and a controller 163.

[0084] The drive signal generator 161 can generate drive signals for driving the ultrasonic vibrator UT. The drive signal generator 161 can use an oscillator or the like.

[0085] Modulator 162 can modulate the amplitude of the drive signal to generate a modulated signal. Modulator 162 can modulate the amplitude to adjust the parameters of the carrier frequency of the drive signal and can increase the output efficiency of the ultrasonic vibrator UT. Modulator 162 can modulate the amplitude of the carrier wave based on the amplitude of the analog data. According to embodiments, modulator 162 can use a double-sideband (DSB) scheme, a single-sideband (SSB) scheme, a vestigial sideband (VSB) scheme, or a composite scheme combining SSB and DSB schemes.

[0086] Figure 6 This is a diagram illustrating DSB modulation.

[0087] Figure 5 The modulator 162 can modulate the drive signal using the DSB scheme, which transmits both the upper sideband (USB) and the lower sideband (LSB) simultaneously across the spectrum.

[0088] The DSB scheme can use either a double-side band-suppressed carrier (DSB-SC) scheme where the carrier is not included in the modulating wave, or a double-side band-large carrier (DSB-LC) scheme where the carrier is included in the modulating wave.

[0089] Figure 7 This is a diagram illustrating a waveform obtained by mixing DSB modulation and SSB modulation according to an embodiment of the present disclosure.

[0090] Figure 5 The modulator 162 can perform the initial modulation of the drive signal using the SSB scheme, and can utilize, for example Figure 6 The DSB scheme shown performs two-stage modulation to generate Figure 7 The modulated signal shown is modulated by a composite scheme.

[0091] Figure 5 The controller 163 can adjust the output timing of the modulation signal to determine the ultrasonic output mode. According to embodiments of the present disclosure, the controller 163 can adjust the output timing of the modulation signal such that the output period of each modulation signal includes at least one occurrence per unit time.

[0092] In addition, through Figure 5 After the ultrasonic vibrator UT sends ultrasonic waves, the controller 163 can control the opening of the first window used to drive mosquitoes out of the vehicle.

[0093] Furthermore, when the ultrasonic vibrator UT outputs an ultrasonic signal, the controller 163 can operate... Figure 1The speaker SP used in the vehicle outputs a sound source signal at a predetermined audible frequency.

[0094] In addition, controller 163 can control Figure 1 The display 51 is used to display the information provided by the display. Figure 1 The ultrasonic sensor SU detects the location of the mosquito.

[0095] Therefore, the controller 163 can communicate with the control module of the display 51 or speaker SP in the vehicle via short-range communication or wired communication, and can send requests to control the display 51 or speaker SP to the control module.

[0096] To adjust the output timing of the modulation signal, the controller 163 can identify the mosquito type corresponding to the location information. The location information may be information indicating the location of the ultrasonic generator 100, and may be obtained based on the Global Positioning System (GPS). Therefore, the ultrasonic generator 100 may further include a GPS receiver, or the location information may be obtained externally.

[0097] The types of mosquitoes that appear corresponding to the location information can be pre-stored in the database, as shown in Table 1 below.

[0098] [Table 1]

[0099] GPS coordinates (x, y) Mosquitoes appeared (x1, y1) Mosquito A, Mosquito B (x2, y2) Mosquito C (x3, y3) Mosquito D …… ……

[0100] Referring to Table 1 above, the mosquitoes that appear can be matched with coordinates represented by (latitude, longitude) and stored in the database.

[0101] The controller 163 can identify the killing frequency that matches the mosquito type. To this end, the database can store killing frequency information corresponding to the mosquitoes that appear, as shown in Table 2 below.

[0102] [Table 2]

[0103] Mosquitoes appeared kill frequency Mosquito A f1 Mosquito B f2 Mosquito C f3 …… ……

[0104] Therefore, the controller 163 can select a kill frequency corresponding to the position information and can control the ultrasonic output to output the kill frequency. For example, when the position information is (x1, y1), the controller 163 can select f1 and f2 as kill frequencies, and when the position information is (x2, y2), it can select f3 as the kill frequency.

[0105] According to an embodiment, when a killing frequency that the ultrasonic generator 100 does not support exists among the killing frequencies corresponding to the location information, or when the killing frequency for repelling mosquitoes corresponding to the location information is not set, the controller 163 can control the output timing of the ultrasonic signal using a cleaning mode for cleaning within a specific frequency range. The output timing of the ultrasonic signal can be a procedure for adjusting the output timing of the modulation signal output by the modulator 162.

[0106] Figure 8 This is a diagram showing the ultrasonic output in cleaning mode.

[0107] Figure 5 The controller 163 can control the cleaning mode, ensuring that each of the multiple kill frequencies is output at least once within a predetermined unit of time. The controller 163 can, for example, Figure 8 The ultrasonic output mode shown in the cleaning mode is used to repel various mosquitoes.

[0108] According to an embodiment, the controller 163 can selectively repel specific mosquitoes by prioritizing the transmission of killing frequencies targeted at specific mosquitoes. For example, when the location information is (x1, y1), the controller 163 can prioritize the output of f1 and f2 as killing frequencies. When f1 is a first frequency and f2 is a second frequency, the controller 163 can drive the first ultrasonic vibrator UT1 at least once per unit time to output a first ultrasonic signal at the first frequency, and drive the second ultrasonic vibrator UT2 at least once to output a second ultrasonic signal at the second frequency.

[0109] According to an embodiment, the controller 163 can adjust the output timing so that the timing of the first ultrasonic signal and the second ultrasonic signal being output does not overlap, thereby reducing the interference between the first ultrasonic signal and the second ultrasonic signal.

[0110] Figure 9 This is a diagram showing the ultrasonic output in lethal mode.

[0111] Figure 5 The controller 163 can be accessed via Figure 9 The killing pattern shown is designed to repel specific mosquitoes.

[0112] Figure 10 This is a diagram showing the hybrid mode obtained through a combination of sweeping and killing modes.

[0113] like Figure 9 As shown, Figure 5 The controller 163 can control the output timing of the ultrasonic signal, so that while sweeping the range of the first frequency and the second frequency within a unit time, the first frequency and the second frequency are output alternately.

[0114] Controller 163 can be accessed via, for example Figure 10 The system combines sweeping and killing modes to target specific mosquitoes while preventing the approach of various mosquitoes.

[0115] Therefore, the controller 163 can perform artificial intelligence learning by using location information and the appearance of mosquitoes as input values, and can adjust the controller based on the learning results. Figure 5 The output timing of the modulated signal output by modulator 162.

[0116] Figure 11 and Figure 12 This is a diagram illustrating an embodiment of an ultrasonic vibrator.

[0117] Reference Figure 11 , Figure 5 The ultrasonic vibrator UT may include a first ultrasonic vibrator UT1 for outputting a first frequency mode and a second ultrasonic vibrator UT2 for outputting a second frequency mode. The first ultrasonic vibrator UT1 and the second ultrasonic vibrator UT2 can output ultrasonic waves in a frequency sweep mode within a certain range.

[0118] According to an embodiment, the first ultrasonic vibrator UT1 can output ultrasonic waves with a sweep frequency range of 28 kHz to 32 kHz. Furthermore, the second ultrasonic vibrator UT2 can output ultrasonic waves with a sweep frequency range of 78 kHz to 82 kHz.

[0119] Reference Figure 12 An ultrasonic vibrator UT may include a first ultrasonic vibrator UT1 for outputting a first frequency mode and a second ultrasonic vibrator UT2 for outputting a second frequency mode. Both the first ultrasonic vibrator UT1 and the second ultrasonic vibrator UT2 can output ultrasonic waves with a specific frequency.

[0120] According to an embodiment, the first ultrasonic vibrator UT1 can output ultrasonic waves with a frequency of 30 kHz. Furthermore, the second ultrasonic vibrator UT2 can output ultrasonic waves with a frequency of 80 kHz.

[0121] Figure 13 This is a diagram showing the output modes of the first and second ultrasonic vibrators. Figure 13 It can be Figure 12 The output modes of the ultrasonic vibrators are shown. Therefore, the first ultrasonic vibrator UT1 can output 30kHz ultrasonic waves, and the second ultrasonic vibrator UT2 can output 80kHz ultrasonic waves.

[0122] Reference Figure 13The first frequency mode output by the first ultrasonic vibrator UT1 and the second frequency mode output by the second ultrasonic vibrator UT2 can be output with different phases. According to an embodiment, the phase of the first frequency mode output by the first ultrasonic vibrator UT1 and the second frequency mode output by the second ultrasonic vibrator UT2 can be set to a delay of 1 / 4 period. In other words, the amplitudes of the first and second frequency modes can be set so that the amplitude of the second frequency mode is maximized at the point where the amplitude of the first frequency mode is lowest, thereby increasing the mosquito-repelling effect. The first and second frequency modes can be set to a smooth fade-in / fade-out scheme.

[0123] Figure 14 This is a flowchart illustrating a control method for an ultrasonic generator according to an embodiment of the present disclosure. Specifically, Figure 14 The control method for an ultrasonic generator installed in a vehicle is described.

[0124] Reference Figure 14 A control method for an ultrasonic generator according to an embodiment of the present disclosure will be described.

[0125] In S1601, Figure 1 The ultrasonic sensor SU can detect mosquitoes in vehicles.

[0126] In S1602, Figure 1 The ultrasonic generator 100 can send ultrasonic waves for the first time.

[0127] The initial ultrasound could utilize resonance to impact the mosquito. Therefore, Figure 5 The controller 163 can output ultrasonic waves through ultrasonic vibrators UT1 and UT2. The controller 163 can operate at least one of the first ultrasonic vibrator UT1 or the second ultrasonic vibrator UT2.

[0128] In S1603, controller 163 can open the first window to repel mosquitoes.

[0129] According to an embodiment, the first window can be positioned based on the passenger's location. The passenger's location can be identified using an ultrasonic sensor SU. Alternatively, the passenger's location can be identified using a monitoring device within the vehicle. For example, the passenger's location can be identified using a pressure sensor located on the seat within the vehicle. Optionally, the passenger's location can be identified using a camera capturing images of the vehicle's interior.

[0130] According to another embodiment, the first window can be configured with the location of the mosquito in mind. For example, the controller 163 can select the window closest to the mosquito's location as the first window.

[0131] Figure 15 This is a flowchart describing a method for detecting mosquitoes using an ultrasonic sensor.

[0132] Reference Figure 15 In S1701, Figure 1 The ultrasonic sensor SU can send ultrasonic signals for sensing.

[0133] In S1702, the ultrasonic sensor SU can identify patterns of reflected signals, where the ultrasonic signals used for sensing are reflected from the target.

[0134] In S1703, the ultrasonic sensor SU can identify whether the pattern of the reflected signal corresponds to the sound of a mosquito.

[0135] When the pattern of the reflected signal corresponds to the sound of a mosquito, in S1704, the ultrasonic sensor SU can determine that the target is equivalent to a mosquito.

[0136] In addition, the ultrasonic sensor SU can determine the location of the mosquito. When the target in S1704 is a mosquito, the ultrasonic sensor SU can determine the target's location.

[0137] Figure 16 This is a diagram illustrating a method for determining the location of a mosquito using an ultrasonic sensor.

[0138] Reference Figure 16 , Figure 1 The ultrasonic sensor SU can determine the position of a mosquito on the surface of a vehicle. This surface can be a plane level with the road surface. The ultrasonic sensor SU can determine the mosquito's position to identify which window it is closest to. For example, if the mosquito is located in area A1, the ultrasonic sensor SU can determine that window W1 is the closest window to the mosquito.

[0139] According to another embodiment, the ultrasonic sensor SU can determine only the two-dimensional (2D) position information of the mosquito on a plane. The ultrasonic sensor SU can send the mosquito's two-dimensional position information to... Figure 1 The controller 163 of the ultrasonic generator 100. The controller 163 can determine, based on two-dimensional position information, which area A1 to A4 the mosquito belongs to and which window is closest to the mosquito.

[0140] Figure 17 This is a flowchart describing the procedure for opening the first window.

[0141] Reference Figure 17 The program that opens the first window can be Figure 14 The procedure shown is the procedure after the first ultrasonic wave is sent.

[0142] In operation S1901, Figure 5 The controller 163 can determine the location of the mosquito. The controller 163 can determine exactly where the mosquito is located on the surface of the vehicle.

[0143] In S1902, the controller 163 can determine the first window to use for repelling the mosquito based on the mosquito's location. The controller 163 can select the window closest to the mosquito's location as the first window. For example, when the mosquito's location is determined to be... Figure 16 When the location of the mosquito is determined to be in area A1, the controller 163 can select window W1 as the first window. Optionally, when the location of the mosquito is determined to be in area A2, the controller 163 can select window W2 as the first window; when the location of the mosquito is determined to be in area A3, the controller 163 can select window W3 as the first window; and when the location of the mosquito is determined to be in area A4, the controller 163 can select window W4 as the first window.

[0144] In S1903, the controller 163 can determine whether the mosquito's location is within a threshold distance from the first window. This threshold distance can be determined as the distance at which the mosquito can be easily driven away through the window, for example, approximately 15 cm.

[0145] When the distance between the mosquito and the first window is less than a threshold distance, in S1904, the controller 163 can open the first window. When the first window is opened, the mosquito, which has been hit by the first ultrasonic wave, is likely to be driven out of the vehicle through the first window.

[0146] When the distance between the mosquito and the first window exceeds a threshold distance, in step S1905, the controller 163 can open the second window without opening the first window. Opening the second window can be a procedure that guides outside air to drive the mosquito to the first window. For this purpose, the controller 163 can select a window located in the opposite direction to the first window relative to the mosquito as the second window. For example, when the mosquito is located in area A2, the first window can be selected as window W2, and the second window can be selected as window W1.

[0147] After the second window is opened, in S1906, controller 163 can send ultrasonic waves a second time. Mosquitoes can be pushed to the edge of the vehicle interior by the air introduced from the outside through the second window. Then, when the ultrasonic waves are sent a second time, the mosquitoes are likely to be impacted and find refuge.

[0148] After S1906, controller 163 can again determine the mosquito's location and identify the first window via S1901. When entering S1901 after S1906, via S1905, the mosquito may be pushed to the edge of the vehicle interior by air introduced from the outside through the second window. Therefore, in S1903, the probability that the mosquito's location will be less than a threshold distance from the first window may become very high. Therefore, controller 163 can drive the mosquito out of the vehicle via S1904.

[0149] Figure 18 This is a flowchart describing a method for repelling mosquitoes in a vehicle using an ultrasonic generator according to another embodiment of the present disclosure.

[0150] Reference Figure 18 A method for repelling mosquitoes in a vehicle using an ultrasonic generator, according to another embodiment, is described.

[0151] In S2001, Figure 1 The ultrasonic sensor SU can detect mosquitoes. According to an embodiment, the ultrasonic sensor SU can emit ultrasonic waves and can identify mosquitoes based on the reflected signals reflected from the target.

[0152] In S2002, the ultrasonic sensor SU can determine the location of mosquitoes. The ultrasonic sensor SU can determine the position of mosquitoes on a plane based on the distance and direction of the mosquitoes.

[0153] The ultrasonic sensor SU can send the location of the mosquito to Figure 1 The controller 163 of the ultrasonic generator 100.

[0154] In S2003, the controller 163 can determine whether the distance between the mosquito's position and the window is within a threshold distance. The window used as the standard for determining the mosquito's position can be the window closest to the mosquito's position. The threshold distance can be predetermined and can be set to a level where the mosquito is easily repelled by the ultrasonic wave. According to an embodiment, the threshold distance can be set to approximately 15 cm.

[0155] When the distance between the mosquito's location and the window is less than a threshold distance, in S2004, the controller 163 can identify that window as the first window. In other words, the controller 163 can identify a window located within the threshold distance from the mosquito's location as the first window.

[0156] In S2005, controller 163 can be accessed via... Figure 5 The ultrasonic vibrator UT sends ultrasonic waves.

[0157] In S2006, the controller 163 can open the first window. To this end, the controller 163 can generate a first window control signal. The first window control signal can be a control signal capable of directly opening the first window. Optionally, the first window control signal can be provided to a control module that controls the vehicle's drive system. This control module can control the opening of the first window.

[0158] After sending the ultrasonic wave, in S2007, the controller 163 can determine whether a mosquito has been detected in the vehicle. To do this, the controller 163 can operate the ultrasonic sensor SU. As described above, the ultrasonic sensor SU can sense whether a mosquito is present in the vehicle.

[0159] When no mosquitoes are detected in the vehicle, the operation of the ultrasonic generator 100 can be stopped.

[0160] Optionally, the ultrasonic generator 100 may repeat S2005 while mosquitoes are still detected in the vehicle.

[0161] When the distance between the mosquito's location and the window exceeds a threshold distance, in S2008, the controller 163 can send ultrasonic waves through the ultrasonic vibrators UT1 and UT2.

[0162] In S2009, the controller 163 can detect the mosquito's position again. The mosquito is likely to have been moved by the ultrasonic waves in S2008. Therefore, the controller 163 can determine whether the mosquito is near the window. To do this, the controller 163 can operate the ultrasonic sensor SU.

[0163] In S2010, the controller 163 can determine whether the distance between the mosquito's location and the window is within a threshold distance.

[0164] When the distance between the mosquito's location and the window is within the threshold distance, the controller 163 can continue with S2004.

[0165] When the distance between the mosquito and the window is not within a threshold distance, in S2011, the controller 163 can open a second window. The second window can be selected from any window other than the one closest to the mosquito. The second window can be used to drive the mosquito to the window through outside air, and this window can be selected from windows located in the opposite direction to the window closest to the mosquito.

[0166] In S2012, the controller 163 can send ultrasonic waves again. After driving the mosquitoes to an area near the window in S2011, the controller 163 can send ultrasonic waves to apply a secondary impact to the mosquitoes.

[0167] Next, controller 163 can perform S2009 again.
