Description

Technical Field

[0001] The invention belongs to the technical field of automobile control, and in particular relates to a vehicle waking-up method. Background Art

[0002] As automobiles develop towards new energy and intelligence, more and more vehicles are equipped with devices such as smart voice assistants to achieve human-computer interaction and control of the vehicle, freeing the hands of drivers or passengers.

[0003] As one of the ways to unlock a car, app unlocking can achieve keyless unlocking and eliminate the need to carry a conventional mechanical key, and has been widely used. However, when the driver's phone and vehicle are in a weak signal and no other phone-based unlocking method is set, the vehicle cannot be woken up, making it impossible to enter the car and drive the vehicle. Summary of the invention

[0004] The problem to be solved by the present invention is to provide a vehicle wake-up method, so that when the mobile phone and the vehicle are in a weak signal and the vehicle cannot be unlocked by using an application unlocking, the vehicle can be woken up and controlled.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a vehicle wake-up method, based on a vehicle with set vehicle wake-up audio, registered driver's voiceprint information and head portrait information, a low-speed sound prompt device, an external camera and an external microphone, comprising the following steps: a. The microphone outside the vehicle collects the wake-up audio sent from outside the vehicle to the vehicle; b. Determine whether the voiceprint information in the wake-up audio is the registered voiceprint information. If it is, execute step c, otherwise ignore the wake-up audio; c. Determine whether the wake-up audio comes from the driver's side of the vehicle. If so, execute step d, otherwise ignore the wake-up audio; d. Determine whether the camera on the driver's side of the vehicle collects the head image information of the person who issued the wake-up audio. If so, the collected head image information is compared with the registered driver's head image information. If the comparison is successful, the vehicle is controlled to wake up, otherwise, step e is executed; e. The low-speed sound prompt device prompts the person who issued the wake-up audio to walk to the driver's side of the vehicle, look at the camera outside the vehicle and issue the wake-up audio again, and then repeat steps ad. If the comparison is successful, the vehicle is controlled to wake up, otherwise the low-speed sound prompt device prompts that the wake-up operation failed.

[0006] Furthermore, in step c, the driver's location is determined by the wake-up audio data collected by the in-vehicle microphone array in the vehicle. If the driver is not outside the driving seat of the vehicle, the wake-up audio is ignored.

[0007] Furthermore, in step c, the driver's position is determined by the wake-up audio data collected by the external microphone array. If the driver is not outside the vehicle's driving seat, the wake-up audio is ignored. The external microphone array includes two external microphones respectively arranged at the left rear mirror and the right rearview mirror of the vehicle.

[0008] Furthermore, the off-vehicle microphone includes a shell, an upper cover mounted on the shell and forming a PCBA mounting cavity, a PCBA located in the PCBA mounting cavity, and a sound pickup hole waterproof component arranged on the shell.

[0009] Furthermore, an annular groove for limiting the shell is provided in the upper cover, a sealing gasket is provided in the annular groove, the opening of the shell is limited in the annular groove and the sealing gasket is pressed by means of a snap structure provided between the shell and the upper cover.

[0011] Furthermore, a first annular boss extending inwardly and a second annular boss extending outwardly are provided on the housing, and the first annular boss and the second annular boss are coaxially arranged to form a sound pickup hole waterproof component installation cavity; A sealing plate for closing the opening of the first annular boss is provided at the bottom of the first annular boss, and a sound pickup hole is provided at the center of the sealing plate, and an EVA pad is provided between the sealing plate and the silicon microphone on the PCBA; A drainage groove is provided at the end of the second annular boss, and a mask for closing the opening of the second annular boss is mounted on the end of the second annular boss. A plurality of strip-shaped mask sound channels are provided on the mask and drainage holes are provided on the outer side of the drainage groove.

[0012] Furthermore, the sound pickup hole waterproof component includes a waterproof sound-permeable membrane, a first spacer, a second spacer and a dustproof net which are sequentially arranged from inside to outside in the sound pickup hole waterproof component installation cavity. A strip-shaped spacer sound channel leading to the sound pickup hole is provided between the first spacer and the second spacer, and the spacer sound channel is parallel to and staggered with the mask sound channel. The first spacer is provided with a first groove, and the second spacer is provided with a second groove which cooperates with the first groove to form a drainage structure leading to the drainage groove.

[0013] Furthermore, an odd number of first grid bars extending upward and protruding from the first spacer are provided in the through hole of the first spacer.

[0018] See attached Figure 1 The present invention provides a vehicle wake-up method to solve the problem that the driver cannot wake up the vehicle through a mobile phone app when the network signal is weak or there is no network and the mobile phone Bluetooth or NFC unlocking is not set. In conventional scenarios, the vehicle wake-up can also be achieved by the method of the present invention.

[0019] The method of the present invention is based on a new energy vehicle with set vehicle wake-up audio, registered driver's voiceprint information and profile picture information, a low-speed sound prompt device, an external camera (such as a side rear-view camera located outside the vehicle and on the driver's side, etc.) and an external microphone.

[0020] The method of the present invention comprises the following steps.

[0021] a. The microphone outside the vehicle collects the wake-up audio sent from outside the vehicle to the vehicle.

[0022] b. Determine whether the voiceprint information in the wake-up audio is the registered voiceprint information. If yes, execute step c; otherwise, ignore the wake-up audio.

[0023] c. Determine whether the wake-up audio comes from the driver's side of the vehicle. If so, execute step d; otherwise, ignore the wake-up audio. By limiting the wake-up audio to the driver's side of the vehicle, you can avoid erroneous vehicle wake-up operations, and at the same time, after the vehicle wakes up successfully, the driver can open the door to drive or perform other operations.

[0024] In this step, the driver's location can be determined by the wake-up audio data collected by the external microphone array. If the driver is not outside the vehicle's driving position, the wake-up audio is ignored. In this embodiment, the external microphone array includes two external microphones respectively arranged at the left and right rearview mirrors of the vehicle, so as to determine which side of the external microphone the collected wake-up audio is closer to, thereby determining whether to ignore the wake-up audio.

[0025] Alternatively, the driver's location may be determined by wake-up audio data collected by an in-vehicle microphone array. If the driver is not outside the vehicle's driving seat, the wake-up audio is ignored.

[0026] d. Determine whether the camera on the driver's side of the vehicle has captured the head portrait information of the person who issued the wake-up audio. If so, compare the captured head portrait information with the head portrait information of the registered driver. If the comparison is successful, control the vehicle to wake up, otherwise execute step e. By comparing the two features of voiceprint and head portrait information, it can be ensured that the operation of the vehicle is performed by authorized personnel to prevent misjudgment when a person with a similar voiceprint or head portrait operates. At the same time, the driver may be in a position where the head portrait cannot be collected, resulting in the inability to compare the voiceprint and head portrait, so it is necessary to prompt the driver to walk to the designated position and issue the wake-up audio again.

[0027] e. The low-speed sound prompt device prompts the person who issued the wake-up audio to walk to the designated area on the driver's side of the vehicle, look at the camera (to ensure that the camera can collect complete head portrait information) and issue the wake-up audio again, and then repeat steps ad. If the comparison is successful, the vehicle is controlled to wake up, otherwise the low-speed sound prompt device is used to prompt that the wake-up operation failed. If the wake-up audio is not received again within a period of time (such as within 1 minute) after the prompt, the wake-up audio is ignored or the wake-up operation fails.

[0028] See attached Figure 2-13 Another inventive point of the present invention is the structure of the off-vehicle microphone. The off-vehicle microphone comprises a housing 1, an upper cover 2 mounted on the housing 1 and forming a PCBA mounting cavity, a PCBA 3 located in the PCBA mounting cavity, and a sound pickup hole waterproof component arranged on the housing 1.

[0029] See attached Figure 3 and 10An annular groove 2-1 for limiting the housing 1 is provided in the upper cover 2, and a sealing gasket 5 is provided in the annular groove 2-1. The opening of the housing 1 is limited in the annular groove 2-1 and the sealing gasket 5 is pressed by means of a buckle structure 4 provided between the housing 1 and the upper cover 2 to form a sealing structure between the housing 1 and the upper cover 2. The buckle structure 4 is provided around the housing 1 and the upper cover 2 to ensure the stability of the connection.

[0030] See attached Figure 5 and 11 In order to achieve waterproofing of the microphone and the matching cables, a cable waterproofing assembly is provided on the outer side of the threading hole 2-2 in the upper cover 2. The cable waterproofing assembly includes a harness plug 6 disposed in the waterproof annular boss 2-3 on the outer side of the upper cover 2 and a plug cover 7 connected with the waterproof annular boss 2-3 so that the harness plug 6 can press the cable passing through the harness plug 6. In the process of the plug cover 7 being connected with the waterproof annular boss 2-3 by snapping, the harness plug 6 will be compressed to reduce the wire hole on it and press the cable, thereby achieving waterproofing.

[0031] See attached Figure 2 , 3 , 12 and 13, in order to provide sufficient installation space for the sound pickup hole waterproof component, a first annular boss 1-1 extending inward (i.e., inside the PCBA installation cavity) and a second annular boss 1-2 extending outward (i.e., outside the shell 1) are provided on the shell 1, and the first annular boss 1-1 and the second annular boss 1-2 are coaxially arranged so that the cavities of the two together form a sound pickup hole waterproof component installation cavity 1-3.

[0032] A sealing plate 1-4 is provided at the bottom of the first annular boss 1-1 to close the opening of the first annular boss 1-1, and a sound pickup hole 1-5 is provided at the center of the sealing plate 1-4, and an eva pad 8 is provided between the sealing plate 1-4 and the silicon microphone on the PCBA 3. The sound pickup hole 1-5 is in a trumpet shape that shrinks toward the silicon microphone.

[0033] A drainage groove 1-6 is provided at the end of the second annular boss 1-2 to facilitate timely drainage of water in the cavity.

[0034] In a specific implementation, the first annular boss 1 - 1 , the second annular boss 1 - 2 , the sealing plate 1 - 4 and the housing 1 are an integral structure and are formed in one step by a mold.

[0035] A mask 9 for closing the opening of the second annular boss 1-2 is mounted on the end of the second annular boss 1-2. A plurality of strip-shaped mask sound channels 9-1 are provided on the mask 9 and drainage holes 9-2 are provided on the outer side of the drainage groove 1-6.

[0036] See attached Figure 3 , 6-9, the above-mentioned sound pickup hole waterproof component includes a waterproof sound-permeable membrane 10, a first spacer 11, a second spacer 12 and a dustproof net 13 which are arranged in sequence from the inside to the outside in the sound pickup hole waterproof component installation cavity 1-3.

[0037] A strip-shaped spacer sound channel a leading to the sound pickup hole 1-5 is provided between the first spacer 11 and the second spacer 12. The spacer sound channel a is parallel to the mask sound channel 9-1 and staggered. The width of the spacer sound channel a is smaller than the width of the mask sound channel 9-1. The staggered setting of the two sound channels can effectively prevent the impact of water, greatly reduce the impact force of the water flow, and avoid the water flow directly impacting the waterproof sound-permeable membrane 4, so that the microphone can reach the IP69K protection level. A diffusion groove 9-3 is provided in the mask 9. The diffusion groove 9-3 is located at the end of the mask sound channel 9-1 and its width is greater than the width of the mask sound channel 9-1 so that the spacer sound channel a can be located below the diffusion groove 9-3 to ensure that the sound can enter the spacer sound channel a.

[0038] A first groove 11-1 is provided on the first spacer 11, and a second groove 12-1 is provided on the second spacer 12 to cooperate with the first groove 11-1 to form a drainage structure leading to the drainage groove 1-6. The first groove 11-1 is L-shaped, and the vertical end of the L-shape runs through the entire first spacer 11, and the other end is located at the bottom of the first spacer 11 and communicates with the through hole therein, so that the water in the through hole can flow out of the microphone through the first groove 11-1, the second groove 12-1, the drainage groove 1-6 and the drainage hole 9-2.

[0039] An odd number of first grille bars 11-2 extending inward and outward of the through hole are provided on the first spacer 11. A conical boss 11-5 with a conical cross section extending toward the first groove 11-1 is provided at the bottom of the first grille bar 11-2 located in the middle. The conical boss 11-5 is located directly above the sound pickup hole 1-5, which can prevent the sound pickup hole 1-5 from being directly impacted by water; the inclined surface on the conical boss 11-5 can reflect water at a certain angle to the inclined surface of the sound pickup hole 1-5 or other positions of the spacer, avoiding direct impact on the sound pickup hole. The space on both sides of the conical boss 11-5 constitutes a buffer space for impact water, reducing the pressure of the water flow.

[0040] An even number of second grid bars 12-2 extending downward and protruding from the second spacer 12 and inserted into the gaps between adjacent first grid bars 11-2 are provided in the through hole of the second spacer 12. The number of first grid bars 11-2 is one more than the number of second grid bars 12-2. In this embodiment, three first grid bars 11-2 are provided, and two second grid bars 12-2 are provided. After the two spacers are installed, the top surface of the first grid bar 11-2 is flush with the top surface of the second spacer 12.

[0041] A channel groove b is provided on the first grille bar 11-2 to cooperate with the second grille bar 12-2 to form a spacer sound channel a, or a channel groove b is provided on the second grille bar 12-2 to cooperate with the first grille bar 11-2 to form a spacer sound channel a. In this embodiment, the channel groove b is provided on the first grille bar 11-2. The inner sides of the first grille bars 11-2 located on both sides are provided with channel grooves b, and the first grille bar 11-2 located in the middle position is provided with channel grooves b on both sides.

[0042] In order to facilitate the positioning of the two spacers, a positioning hole 11 - 3 is provided on the top surface of the first spacer 11 , and a positioning boss 12 - 3 matching with the positioning hole 11 - 3 is provided on the bottom surface of the second spacer 12 .

[0043] In order to facilitate positioning of the two spacers in the cavity, a limiting boss 11-4 is provided on the circumferential surface of the first spacer 11, and a limiting groove 1-7 matching the limiting boss 11-4 is provided in the cavity of the second annular boss 1-2.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
