Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.
In order to make the technical solutions of the present application better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The rearview mirror is used as an essential accessory of a vehicle and plays an important role in driving safety of a driver. In order to clearly observe the road condition behind the vehicle, the driver can adjust the actual position of the driver seat according to the actual position of the driver seat, for example, the driver manually adjusts the rearview mirror to the visual field position meeting the driving requirement of the driver by using a rearview mirror adjusting key. The visual field position is usually determined by the specific positions of the two eyes of the driver during driving.
Since the same vehicle or the same type of vehicle can be driven by several people with different body proportions, for example, different family members drive the same vehicle, different taxi drivers drive the same type of vehicle, and the drivers with different body proportions must adjust the position of the rearview mirror according to their own needs. Furthermore, the driving posture of the driver may be constantly changed while the vehicle is running, which also makes adjustment of the rear view mirror troublesome.
In order to solve the above problems, the inventors have made extensive studies to provide a method for controlling a vehicle mirror according to an embodiment of the present application, which includes obtaining a sound source position of a target object, the sound source position being used to represent a spatial position of a sound organ from which the target object emits sound, determining a binocular position of the target object according to the sound source position, and further adjusting the vehicle mirror to the target position according to the binocular position. Thus, the sound source localization is combined with the adjustment of the vehicle's rearview mirrors so that the vehicle can dynamically adjust the rearview mirrors to the optimal positions automatically according to the binocular positions of the driver. The following first describes an application scenario of the control method for the vehicle rearview mirror according to the present application.
As shown in fig. 1, in some embodiments, the control method of the vehicle rearview mirror provided in the embodiments of the present application may be applied to a control system 400 of the vehicle rearview mirror, where the control system 400 of the vehicle rearview mirror includes a microphone array and a vehicle rearview mirror 420. Wherein the microphone array may include a plurality of microphones 410, and the vehicle rear view mirror may include an exterior rear view mirror or/and an interior center rear view mirror.
Alternatively, a plurality of microphones 410 may be installed at different positions in the vehicle compartment, respectively, for picking up the voice uttered by the driver. As shown in fig. 2, a microphone array formed by a plurality of microphones 410 is installed at different positions on the roof of the vehicle cabin, and it should be noted that the distribution positions and the number of the plurality of microphones 410 may be arranged according to the specific vehicle type.
For example, a two-row seated vehicle model may employ an arrangement of 4 microphones, front left, front right, back left, back right, respectively. A three-row seated vehicle model may employ an arrangement of 6 microphones, front left 401, front right 402, middle left 403, middle right 404, back left 405, and back right 406. For a main driver, the specific position of the sounding part of the driver can be located only by the front left 401, front right 402 and middle left 403 microphones, and the microphones at the positions of the front left 401, the front right 402 and the middle left 403 can be installed at the positions which are not shielded by the driver as far as possible, so that sound reflection is prevented, and the accuracy of sound collection is influenced.
As an embodiment, during driving of the vehicle, the plurality of microphones 410 may collect the sound emitted by the driver, and determine the position of the emitted sound, i.e., the nose/mouth of the driver, according to the sound, and further, obtain the positions of the eyes of the driver according to the nose/mouth, so as to adjust the vehicle rearview mirror to a position suitable for the driver to view the road condition behind the vehicle according to the positions of the eyes.
For example, as shown in fig. 3, for a vehicle with three rows of seats, an arrangement of 6 microphones may be adopted, during the running process of the vehicle, the 6 microphones are responsible for collecting sound and transmitting the collected sound to an amplifier, the amplifier amplifies an Analog Signal of the collected sound, and simultaneously an Analog-to-Digital Converter (ADC) transmits the collected sound to a Digital Signal Processor (DSP) for Processing, further, since the DSP and a System on Chip (SoC) may communicate with each other through an Integrated Circuit bus (IIC)/Serial Peripheral Interface (SPI), the DSP transmits the processed Signal to the SoC and performs voice recognition on the sound Signal by the SoC, the SoC communicates with the microcontroller, and the microcontroller communicates with a Controller Area Network (Controller Area Network) through the SoC, and sending the CAN information to be executed to the vehicle CAN gateway module, and further controlling and adjusting the rearview mirror through the CAN gateway module. Embodiments in the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 4, fig. 4 illustrates a control method of a vehicle rearview mirror according to an embodiment of the present application, where the control method of the vehicle rearview mirror may include the following steps S110 to S130.
Step S110: and acquiring the sound source position of the target object, wherein the sound source position is used for representing the spatial position of a sounding organ of the target object for sounding.
In order to facilitate a target object to accurately acquire road condition information behind a vehicle from a rearview mirror in the driving process, the position of the vehicle rearview mirror can be adjusted to an optimal position according to the position of the eyes of the target object, and the positions of the eyes can be calculated according to the position of the nose/mouth of the target object, so that the vehicle can acquire the sound emitted by the nose/mouth of the target object through a microphone array, and determine the specific position of the nose/mouth of the target object according to a sound source positioning technology to further determine the positions of the eyes of the target object, wherein the target object can be a driver or other passengers of the vehicle, the target object is defaulted as the driver under the normal condition, the vehicle can identify other passengers as the target object according to sound source positioning, for example, when the passengers in a passenger seat of a passenger seat send control commands to a central rearview mirror, at this time, the vehicle may regard the occupant as a target object.
Wherein, the sound source position refers to a specific spatial position of the nose/mouth where the target object emits sound in the vehicle cabin, and it is noted that, in the embodiment of the present application, for convenience of calculation, the spatial positions of the nose/mouth and the eyes may belong to the same spatial coordinate system.
As an embodiment, the vehicle may collect multiple paths of sound information emitted by the target object through the microphone array, and calculate the spatial position of the nose/mouth of the sound emitted by the target object by using a sound source localization algorithm according to the multiple paths of sound information, and further use the spatial position of the nose/mouth as the sound source position.
Specifically, as shown in fig. 5, when the microphones 101 and 102 collect the sound information 105 emitted from the mouth 104 of the target object 103, a spatial cartesian coordinate system is formed by using a microphone array formed by the microphones 101 and 102, and the position of the sound source in the space is determined according to different linear arrays, or a plane array and a spatial array are constructed according to different installation positions of the microphones to perform the calculation of sound source positioning.
Step S120: and determining the binocular position of the target object according to the sound source position.
Wherein, the binocular position refers to the spatial position of the two eyes of the target object in the vehicle compartment, and can be determined after determining the position of the nose/mouth of the target object because the distribution of the human five sense organs on the face has small differences. As an embodiment, when the sound source position of the target object is acquired, the binocular position of the target object may be calculated based on the sound source position, for example, the binocular position may be located at 8cm directly above the sound source position, and the horizontal distribution area may be about 4cm long.
Step S130: and adjusting the vehicle rearview mirror to the target position according to the binocular positions.
The target position refers to a position where a vehicle rearview mirror which is most suitable for a target object to view road conditions behind a vehicle is located, and the target position can be a pre-stored position which is obtained by adjusting the target object in advance according to the body proportion and driving habits of the target object, or can be default set by a vehicle manufacturer according to human factors engineering and related technologies of vehicle manufacturing neighborhood in the vehicle production process.
As an embodiment, when the vehicle determines the binocular positions of the target objects, the corresponding target positions may be determined according to the binocular positions, and then the vehicle rearview mirrors may be adjusted to the target positions. Specifically, after determining the binocular position, the vehicle may query a target position corresponding to the current binocular position from factory settings of the vehicle, for example, when the binocular position is within a spatial position range a to B, the target position of the corresponding vehicle rearview mirror is M.
Illustratively, as shown in fig. 5, during the driving of the vehicle, the microphone array formed by the microphones 101 and 102 may collect the sound signal 105 emitted by the target object 103 in real time, and use a sound localization algorithm to obtain the spatial position of the mouth 104 as the sound source position, and further calculate a binocular position 106 based on the sound source position, after obtaining the binocular position, the vehicle determines the target position of the vehicle rearview mirror 107, and further, adjusts the vehicle rearview mirror 107 to the target position.
In the embodiment of the application, the sound source position of the target object is obtained, the sound source position is used for representing the spatial position of a sounding organ which makes sound by the target object, the binocular position of the target object is determined according to the sound source position, and further, the vehicle rearview mirror is adjusted to the target position according to the binocular position. Therefore, the sound source positioning is combined with the adjustment of the rearview mirror of the vehicle, so that the vehicle can automatically adjust the rearview mirror to the optimal position according to the binocular position of the driver, and the adjustment efficiency of the rearview mirror is effectively improved.
As shown in fig. 6, fig. 6 schematically illustrates another control method of a vehicle rearview mirror provided in an embodiment of the present application, and the control method of the vehicle rearview mirror may include the following steps S210 to S250.
Step S210: and acquiring sound information emitted by the target object through the microphone array.
The posture of the target object for driving the vehicle is usually changed continuously during driving, and therefore, the position of the target object adjusted to the vehicle rearview mirror before driving may not meet the optimal position corresponding to the current posture in real time. Therefore, the vehicle can collect the sound information of the driver to carry out sound source positioning, so that the vehicle rearview mirror can be adjusted in real time. Wherein the sound information refers to the sound emitted by the nose/mouth of the target object, it is noted that the sound information may include a control password emitted by the target object for controlling the adjustment of the vehicle rearview mirror.
In some embodiments, the vehicle may collect the sound information emitted by the target object in real time by using the microphone array, and in particular, referring to fig. 7, step S220 may include: step S211 and step S212.
Step S211: and determining a target microphone in the microphone array according to the position in the vehicle where the target object is positioned.
In order to improve the accuracy of the microphone array for acquiring the sound information emitted by the target object, a target microphone may be designated according to the position of the target object to acquire the sound information, wherein the target microphone refers to a microphone in the microphone array that is specifically used for acquiring the sound information of the target object.
As an embodiment, a microphone close to the target object may be selected as the target microphone according to different vehicle models, as shown in fig. 2, and specifically, a microphone in the microphone array located at the front left, front right, and middle left positions of the vehicle compartment may be used as the target microphone.
Step S212: and acquiring sound information emitted by the target object through the target microphone.
As an embodiment, when the vehicle determines the target microphone, whether the target object emits sound may be monitored in real time according to the target microphone, and if it is detected that the target object emits sound, sound information emitted by the target object may be acquired, and optionally, after acquiring the sound information, the target microphone may perform preprocessing on the sound information to remove noise and improve accuracy of the sound information.
Step S220: and determining the sound source position according to the sound information.
In one embodiment, after the vehicle acquires the sound information, the vehicle may analyze the sound information to determine the sound source position. Specifically, the sound source position can be calculated by using a sound source positioning algorithm, that is, a spatial geometric relationship is constructed by using the sound source positioning algorithm, and the position of the sound source is estimated for the multi-path sound information based on the established sound source model so as to achieve the sound source positioning capability of a centimeter level, thereby improving the accuracy of sound source positioning.
For example, the vehicle can determine the sound source position by using a voice position recognition method of time delay estimation and space positioning, and for the time delay estimation of the voice signal, the time delay can be estimated by selecting the highest peak of two sections of sound information cross-correlation curves. In the embodiment of the present application, a sound source localization algorithm may be described by a two-dimensional plane parameter distance, specifically, as shown in fig. 8, a known microphone: the first microphone 201, the second microphone 202 and the third microphone 203 have the coordinates of (0, 0), (-d, 0), (d, 0) and t1Is the time difference, t, of the information traveling from the second microphone 202 to the first microphone 2012Is the time difference in the propagation of the information from the first microphone 201 to the third microphone 203, wherein,d，t1，t2the sound information propagation velocity v is a known parameter, and the time delay estimation calculation equation can be used to solve the coordinates l (x, y) of the sound source position, and the calculation equation is as follows:
the coordinates l (x, y) of the position of the sound source can be solved from the above equation (1) and equation (2) in combination. It should be noted that, in the above example, the sound source localization algorithm is described by using a two-dimensional plane parameter distance, in an actual application scenario, a plurality of microphones may be arranged at positions convenient for acquiring sound information of a target object at different heights, so that a three-dimensional space coordinate system may be constructed for multi-channel sound source localization calculation, which is not limited herein.
Step S230: and determining the binocular position of the target object according to the sound source position.
In one embodiment, after the vehicle calculates the coordinates of the sound source position through the sound information, the coordinates of the sound source position may be subjected to a displacement operation to obtain the binocular positions of the target object. For example, the coordinates of the sound source position may be translated upward by 8cm as the coordinates of the binocular position.
Step S240: and determining the target positions corresponding to the binocular positions according to the binocular positions.
The existing computer vision related technologies such as face recognition can also play a role in recognizing/positioning the positions of human eyes, but such schemes are easily affected by the external environment, for example, the illumination intensity can affect the recognition precision, and in addition, a camera device for recognition needs to be additionally arranged, so that the binocular positions are determined by sound source positioning in the embodiment provided by the application, the accuracy of obtaining the binocular positions can be improved, and meanwhile, the vehicle production cost is prevented from being improved due to the addition of additional equipment.
In addition, due to physiological factors such as the height ratio of the human body and the like and the difference of the positions of the driver seats, the optimal angle of each driver for watching the rearview mirror is different, and generally, the rearview mirror has an optimal position, namely a target position, corresponding to the spatial position, for watching the rear road condition at each spatial position where each pair of eyes are located. In some embodiments, the vehicle may determine the target position corresponding to the binocular position according to the binocular position, and specifically, referring to fig. 9, step S240 may include: step S241 and step S242.
In some embodiments, the vehicle may store the target object adjusting the position of the vehicle mirror as the target position so that the target position may be directly obtained and the vehicle mirror adjusted quickly the next time the target object needs to adjust the vehicle mirror.
Step S241: the user identity of the target object is determined.
As an embodiment, when the vehicle acquires the voice information of the target user, voice recognition/voiceprint recognition may be performed on the voice information, and the user identity of the target object may be determined. For example, after the target microphone collects the voice information emitted by the target object, the vehicle analyzes the voice information by using a voiceprint recognition algorithm to determine the user identity of the target object.
Step S242: and determining a target position corresponding to the binocular position of the target object according to the user identity.
As an embodiment, when the vehicle determines the user identity of the target object according to the collected sound information, a historical adjustment position corresponding to a binocular position of the target object may be obtained by the user identity, where the historical adjustment position refers to a position where a rearview mirror of the vehicle is adjusted in a historical record, further, a default adjustment position corresponding to the binocular position may be obtained according to the binocular position of the target object, where the default adjustment position refers to a default position of rearview mirror adjustment obtained by a vehicle manufacturer through a test experiment according to vehicle characteristics (e.g., a vehicle body length, a car height) and the binocular position, further, whether the historical adjustment position matches the default adjustment position may be judged, and if the historical adjustment position matches the default adjustment position, the historical adjustment position is determined as the target position.
Alternatively, the vehicle may query the record of the target object for adjusting the vehicle mirror from the data table recorded with the vehicle mirror adjustment record, so as to obtain the corresponding historical adjustment position, as shown in table 1, where table 1 is the data table of the vehicle mirror adjustment record, and includes an Identity (ID) of the user and the historical adjustment position corresponding to the ID.
Alternatively, as shown in table 2, table 2 includes binocular position ranges and default adjustment positions corresponding to the binocular position ranges. When the binocular position of the target object falls within the range Ai～BiThen, the default adjustment position corresponding to the binocular position can be determined as Di。
Optionally, after determining whether the historical adjustment position matches the default adjustment position, if the historical adjustment position does not match the default adjustment position, the historical adjustment position may be modified. For example, the value of the historical adjustment position corresponding to the user identity is replaced with the value of the default adjustment position corresponding to the current binocular position.
In other embodiments, when the vehicle determines the binocular positions of the target object according to the sound source position, default adjustment positions corresponding to the binocular positions may be acquired, and the corresponding default adjustment positions may be directly determined as the target positions.
Step S250: and adjusting the vehicle rearview mirror to a target position.
In some embodiments, after the vehicle determines the target position through the binocular position, the vehicle rearview mirror may be adjusted according to the target position, as shown in fig. 10, and may enclose a driving side rearview mirror 204, a secondary driving side rearview mirror 205, and an interior center rearview mirror 206 outside the vehicle. Specifically, referring to fig. 11, step S250 may include:
step S251: the current position of the vehicle rearview mirror is acquired.
As an embodiment, when the vehicle determines the target position, the current position α of the vehicle's rearview mirror may be acquired. For example, the current position α of the driving side mirror 204 is acquired1Current position α of the copilot side mirror 2052And the current position alpha of the center rearview mirror 206 in the vehicle3。
Step S252: and judging whether the current position is at the target position.
In order to reduce the adjustment steps of the vehicle rearview mirror and avoid repeated adjustment, when the current position of the vehicle rearview mirror is at the target position, no adjustment is needed. As an embodiment, the vehicle may compare the acquired current position α of the vehicle rearview mirror with a target position β, and determine whether the current position is at the target position, where the target position may be a position range, for example, the target position β ∈ (p, q). Specifically, the vehicle may determine whether the acquired current position α of the vehicle mirror falls within the target position β to determine whether the current position is at the target position.
Step S253: and if the current position is not at the target position, adjusting the position of the vehicle rearview mirror to the target position.
As an embodiment, when it is determined that the current position α of the vehicle mirror is not equal to the target position β, the current position α of the vehicle mirror may be adjusted to the target position β. In particular, different vehicle mirrors may be adjusted.

Therefore, the vehicle can dynamically adjust the vehicle rearview mirror to the optimal view according to the positions of the two eyes in the driving process of the target object, and the driving safety is improved.
As shown in fig. 12, fig. 12 schematically illustrates another control method of a vehicle rearview mirror provided in an embodiment of the present application, and the control method of the vehicle rearview mirror may include the following steps S310 to S340.
Step S310: and when the target object is detected to be in the driver seat, judging whether to acquire a control command.
In order to reduce the operation steps of adjusting the vehicle rearview mirror, the vehicle can store the target position corresponding to the target object, so that when the vehicle rearview mirror needs to be adjusted next time, the adjusted target position for the target user can be found directly from the history record of adjusting the vehicle rearview mirror by the target object, and the vehicle rearview mirror is directly adjusted to the target position adjusted last time, so that the adjustment steps are simplified, and the adjustment efficiency of the vehicle rearview mirror is improved.
The control command refers to a command for instructing the vehicle to adjust the vehicle mirror, which can be generated by the voice of the target object, for example, if the target object sends a voice command "adjust the mirror", the vehicle can recognize the voice command by using a voice recognition algorithm, for example, machine learning/deep learning (Wav2letter + +), and when the target object is determined to send the voice command for controlling the vehicle mirror, the vehicle generates the control command.
As one embodiment, the vehicle may determine whether to acquire the control instruction when it is detected that the target object is seated in the driver's seat. Specifically, whether a driver enters a vehicle compartment or not may be determined by providing a pressure sensor in a driver seat of the vehicle, and when the pressure sensor on the driver seat detects pressure, it may be determined that the target object is in the driver seat, and then, it is determined whether a control instruction is acquired or not.

As an implementation, when the vehicle detects the control instruction, a voice password for generating the control instruction may be acquired, and sound source location may be acquired by performing sound source location on the voice password, and a specific method of sound source location may refer to the description in the above embodiment. In addition, although the target object usually wakes up the vehicle by a voice password to adjust the rearview mirror after getting on the vehicle, the target object may forget to issue the voice password.
As another embodiment, if the control instruction is not acquired, it may be monitored in real time whether the target object sends a voice command or a sound, and then the position of the rearview mirror is adjusted after the binocular position of the target object is located by using the sound information acquired at any time.
In some embodiments, the vehicle may determine the location of the sound source based on the control commands, and thus the location of the eyes to control the rear view mirror. The specific steps may include step S330 and step S340.
Step S330: and determining the binocular position of the target object according to the sound source position.
Step S340: and adjusting the vehicle rearview mirror to the target position according to the binocular positions.
In this embodiment, the specific implementation of step S330 and step S340 may refer to the description of step S120 and step S130 provided in the above embodiments, and are not described herein again.
In other embodiments, the vehicle may determine a user identity of the target object based on the control instruction and directly control the rearview mirror based on the user identity. Specifically, after the vehicle acquires the control command, the target user may be subjected to identity recognition according to the sound information of the control password corresponding to the control command, for example, the user identity of the target object is determined by using a voice recognition algorithm.
Further, when the vehicle determines the user identity of the target object, the history of the adjustment of the vehicle rearview mirror by the target object can be obtained according to the user identity, the adjusted target position for the target user can be found from the history, and the vehicle rearview mirror can be directly adjusted to the adjusted target position last time.
For example, as shown in fig. 13, fig. 13 shows an adjusting method of a vehicle rearview mirror provided in an embodiment of the present application, which adjusts the vehicle rearview mirror according to whether a control instruction is acquired. Specifically, the vehicle may determine whether the acquired control instruction is acquired when it is detected that the target object is in the driver's seat.
Further, if it is determined that the control instruction is acquired, the sound source position of the target object is acquired according to the control instruction, specifically, a control command of the target object may be acquired, sound source positioning is performed according to the control command to acquire the sound source position, then the binocular position of the target object may be determined according to the sound source position, and the vehicle rearview mirror is adjusted to the target position according to the binocular position.
Optionally, if it is determined that the control instruction is not acquired, the vehicle may monitor, in real time, whether the sound information of the target object is acquired through the microphone array, and when the sound information of the target object is acquired, the sound source may be positioned according to the sound information to acquire the sound source position, and then the binocular position of the target object may be determined according to the sound source position, and the vehicle rearview mirror may be adjusted to the target position according to the binocular position. In addition, the control command can be judged to be acquired by performing voice analysis on the sound information, and if the control command is acquired, the vehicle rearview mirror is directly adjusted according to the control command.
In the embodiment of the application, whether a control instruction is acquired or not is judged when the target object is detected to be in a driver seat, if the control instruction is acquired, a sound source position of the target object is acquired according to the control instruction, a binocular position of the target object is determined according to the sound source position, and further, the vehicle rearview mirror is adjusted to the target position according to the binocular position. Therefore, the vehicle can directly adjust the position of the vehicle rearview mirror after acquiring the control command sent by the target object, and can also position the sound source and adjust the vehicle rearview mirror according to the sound information acquired by real-time monitoring. Thus, the number of operation steps for adjusting the vehicle mirror is reduced.
