Accordingly, the vehicle controller (30) can send the received vehicle status information (particularly, a collision occurrence signal) as a trigger signal to the voice processing device (40). Accordingly, the voice processing device (40) outputs passenger boarding position information. That is, the voice processing device (40) can only generate passenger boarding position information before receiving the trigger signal, and can output the generated passenger boarding position information when receiving the trigger signal.
- the vehicle controller (30) may be configured to include, for example, an ECU (Electronic Control Unit).
- ECU Electronic Control Unit
- the voice processing device (40) can generate a voice signal associated with the voice of each passenger in the vehicle (10) in response to the voice of each passenger.
- the voice signal is a signal associated with voices spoken during a specific period of time, and may be a signal representing the voice of each of a plurality of passengers.
- the voice processing device (40) can recognize the voices of passengers separately for each passenger. When multiple passengers speak simultaneously, the voice includes the voices of all passengers who spoke. In order to accurately process the voices of each passenger, it is necessary to separate the voices of each passenger from the voices that include the voices of all passengers.
- a voice processing device (40) can extract (or generate) a separated voice signal associated with each of the voices of the passengers from the voice signal by determining the sound source location of each of the voices of the passengers from the voice signal associated with the voices of multiple passengers and performing sound source separation based on the sound source location.
- the voice processing device (40) can generate a separated voice signal associated with the voice of the passenger located at each boarding position based on the sound source location of the voices (i.e., which may be the boarding position of the passenger).
- the voice processing device (40) can classify the components of the voice signal by the sound source location (i.e., the boarding position of the passenger) and generate a separated voice signal associated with the voice spoken at each sound source location (i.e., the boarding position of the passenger) using the classified components corresponding to each sound source location (i.e., the boarding position of the passenger).
- the voice processing device (40) can generate a first separated voice signal associated with the voice of the first passenger spoken at the first sound source location based on the voice signal.
- the first separated voice signal may have the highest correlation with the voice of the first passenger among the voices of the passengers. In other words, the proportion of the voice component of the first passenger among the voice components included in the first separated voice signal may be the highest.
- the voice processing device (40) can determine the sound source location of each voice of the passengers by using the time delay (or phase delay) between the voice signals associated with the voices of the passengers in the vehicle (10), and generate a separate voice signal corresponding only to the sound source of the specific location. For example, the voice processing device (40) can generate a separate voice signal associated with the voice spoken at a specific location (or direction). Accordingly, the voice processing device (40) can generate a separate voice signal associated with the voice of each passenger.
- the first passenger (SPK1) may be located in a front row left area (FL) of the vehicle (10)
- the second passenger (SPK2) may be located in a front row right area (FR) of the vehicle (10)
- the third passenger (SPK3) may be located in a rear left area (BL) of the vehicle (10)
- the fourth passenger (SPK4) may be located in a rear right area (BR) of the vehicle (10), but embodiments of the present invention are not limited thereto.
- the voice processing device (40) can generate a voice signal associated with the voice of the first to fourth passengers (SPK1 to SPK4) in response to each of the voices of the first to fourth passengers (SPK1 to SPK4).
- the voice signal is a signal associated with voices uttered during a specific time, and may be a signal representing the voices of a plurality of passengers.
- the voice processing device (40) determines the sound source locations (i.e., the boarding locations of the passengers) of the voices of the first to fourth passengers (SPK1 to SPK4) by using the time delay (or phase delay) between the voice signals associated with the voices of the first to fourth passengers (SPK1 to SPK4), and extracts (or generates) a separate voice signal corresponding only to the sound source of the specific location. As illustrated in FIG.
- the voice processing device (40) can generate a voice signal in response to the voices “AAA”, “BBB”, “CCC” and “DDD” and use the generated voice signal to generate a separate voice signal associated with the voice of each passenger (SPK1 to SPK4).
- the voice processing device (40) can match and store a first separated voice signal associated with the voice “AAA” of the first passenger (SPK1) and first sound source location information (i.e., boarding location information of the first passenger) indicating the sound source location of the voice “AAA” (i.e., boarding location of the first passenger (SPK1)) to the left front row (FL) by separating the voice signal according to the location of the sound source.
- first sound source location information i.e., boarding location information of the first passenger
- the voice processing device (40) can match and store a second separated voice signal associated with the voice “BBB” of the second passenger (SPK2) and second sound source location information (i.e., boarding location information of the second passenger) indicating the sound source location of the voice “BBB” (i.e., boarding location of the second passenger (SPK2)) to the right front row (FR).
- SPK2 voice “BBB” of the second passenger
- SPK2 second sound source location information
- the voice processing device (40) can match and store the third separate voice signal associated with the voice “CCC” of the third passenger (SPK3) and the third sound source location information (i.e., the boarding location information of the third passenger) indicating the rear left (BL) as the sound source location of the voice “CCC” (i.e., the boarding location of the third passenger (SPK3)).
- the voice processing device (40) can match and store the fourth separate voice signal associated with the voice “DDD” of the fourth passenger (SPK4) and the fourth sound source location information (i.e., the boarding location information of the fourth passenger) indicating the rear right (BR) as the sound source location of the voice “DDD” (i.e., the boarding location of the fourth passenger (SPK4)).
- the reason why the voice processing device (40) matches and stores the passenger's boarding position and the separated voice signal at the corresponding boarding position is to transmit the passenger's boarding position and the separated voice signal at the corresponding boarding position to the control server (70) via the emergency rescue request device (50) in the event of an accident such as a collision. Since the most reliable bio-signal is voice, in the embodiment of the present invention, the voice signal (i.e., which may be a separated voice signal) for each passenger's boarding position is extracted and stored and then sent when necessary (i.e., when an accident occurs).
- the voice processing device (40) can periodically or aperiodically perform the operations of generating and storing the passenger's voice signal and the passenger's boarding location information as described above.
- the voice processing device (40) receives vehicle status information (particularly, a collision occurrence signal) from the vehicle controller (30), and the vehicle status information (particularly, a collision occurrence signal) at this time may be a trigger signal. Accordingly, when the voice processing device (40) receives the collision occurrence signal (i.e., the trigger signal), it may output passenger boarding position information and passenger voice signal (i.e., a separate voice signal) at the corresponding boarding position in response to the trigger signal. At this time, the passenger boarding position information output may include passenger boarding position information before receiving the collision occurrence signal (i.e., the trigger signal) and passenger boarding position information after receiving the collision occurrence signal (i.e., the trigger signal).
- the passenger boarding position information before receiving the collision occurrence signal may be boarding position information at a time point closest to the time point at which the collision occurrence signal is received among the time points before receiving the collision occurrence signal.
- the passenger's boarding position information after receiving a collision occurrence signal may be the boarding position information at the time point closest to the time point at which the collision occurrence signal was received among the time points after receiving the collision occurrence signal.
- the passenger's voice signal at the corresponding boarding position that is output may include the passenger's voice signal at the corresponding boarding position before receiving the collision occurrence signal (i.e., the trigger signal) and the passenger's voice signal at the corresponding boarding position after receiving the collision occurrence signal (i.e., the trigger signal).
- the passenger's voice signal at the corresponding boarding position before receiving the collision occurrence signal may be a voice signal stored for a predetermined time period prior to the time point at which the collision occurrence signal was received.
- the passenger's voice signal at the corresponding boarding position after receiving the collision occurrence signal may be a voice signal stored for a predetermined time period after the time point at which the collision occurrence signal was received.
- the reason why the passenger's location information and the passenger's voice signal can be output before and after receiving a collision occurrence signal is because, as explained above, the voice processing device (40) stores such information and signals.
- the passenger's boarding location information output from the voice processing device (40) and the passenger's voice signal at the corresponding boarding location can be transmitted to the control server (70) through the emergency rescue request device (50) after being approved by the vehicle controller (30). Meanwhile, the passenger's boarding location information output from the voice processing device (40) and the passenger's voice signal at the corresponding boarding location can be directly approved to the emergency rescue request device (50) and transmitted from the emergency rescue request device (50) to the control server (70).
- the control server (70) can determine whether the passenger has a voice for each vehicle seat and the content of the passenger's voice for each vehicle seat based on the received data. That is, as described above, the boarding position information of the passenger transmitted to the control server (70) includes the boarding position information of the passenger before receiving the collision occurrence signal and the boarding position information of the passenger after receiving the collision occurrence signal. In addition, the voice signal of the passenger at the boarding position transmitted to the control server (70) includes the voice signal of the passenger at the boarding position before receiving the collision occurrence signal and the voice signal of the passenger at the boarding position after receiving the collision occurrence signal.
- control server (70) can more accurately determine the number of passengers inside the vehicle, whether the number of passengers has changed before and after the accident, and the status of the passengers (injured area, degree of injury), etc., through the received boarding position information and voice signals. Due to this, the control server (70) can instruct more accurate and rapid response. For example, as shown in Fig. 2, it can be assumed that the first to fourth passengers (SPK1 to SPK4) were on board the vehicle (10) before the collision occurred, and the second passenger (SPK2) escaped from the vehicle (10) due to the collision of the vehicle (10).
- the voice processing device (40) would have matched and stored the voice signals (i.e., separate voice signals) of the first to fourth passengers (SPK1 to SPK4) by the location of each sound source (i.e., the boarding location of the passenger) before the vehicle collision occurred.
- the voice processing device (40) cannot collect the voice of the second passenger (SPK2), and thus the voice signal at the boarding location of the second passenger (SPK2) cannot be stored.
- the voice processing device (40) will store the voice signals of the passengers (i.e., the first passenger (SPK1), the third passenger (SPK3), and the fourth passenger (SPK4)) present in the vehicle (10) after the vehicle collision (e.g., voice signals related to voices indicating that something hurts or the situation inside the vehicle, etc.).
- the control server (70) receives information on the boarding location of passengers and voice signals before and after receiving such a collision occurrence signal, so that it can determine through the received boarding location information that there were four passengers in the vehicle before the collision and that there were three passengers after the collision. In addition, it can consider one passenger who escaped as being unconscious, dead, or escaped from the vehicle, and it can determine the injured part and degree of the passengers through the received voice signals.
- the voice processing device (40) can receive the vehicle's location information in real time from the vehicle controller (30). Accordingly, the voice processing device (40) can output the vehicle's location information at the time of receiving the collision occurrence signal (i.e., trigger signal) together with the passenger's boarding location information and the passenger's voice signal at the corresponding boarding location.
- the collision occurrence signal i.e., trigger signal
- the voice processing device (40) may receive the vehicle location information at the time of the vehicle collision from the vehicle controller (30) instead of receiving the vehicle location information in real time from the vehicle controller (30). For example, when the vehicle controller (30) receives a collision occurrence signal from the sensor (20), it may receive the vehicle location information at that time together and transmit the collision occurrence signal and the vehicle location information at the time of the vehicle collision to the voice processing device (40).
- the location information of the vehicle at the time of the vehicle collision may be transmitted to the control server (70) through the emergency rescue request device (50) after being authorized to the vehicle controller (30), like the aforementioned passenger boarding location information and the passenger's voice signal at the corresponding boarding location, or may be directly authorized to the emergency rescue request device (50) and transmitted from the emergency rescue request device (50) to the control server (70).
- the emergency rescue request device (50) may be configured to receive passenger boarding location information and transmit the received boarding location information to the control server (70).
- the boarding location information may be received directly from the voice processing device (40) or may be received from the voice processing device (40) through the vehicle controller (30).
- the emergency rescue request device (50) can transmit the current location information of the vehicle (10) and the passenger's voice signal together with the passenger's boarding location information to the control server (70).
- the emergency rescue request device (50) may include a communication unit (not shown) configured to exchange data with the control server (70) using radio waves of various frequencies.
- the communication unit in the emergency rescue request device (50) may exchange data with the control server (70) according to at least one of short-range wireless communication, medium-range wireless communication, and long-range wireless communication.
- a vehicle (10) in which a voice processing device (40) and an emergency rescue request device (50) are installed can transmit passenger boarding position information (i.e., including passenger boarding position information before receiving a collision occurrence signal and passenger boarding position information after receiving a collision occurrence signal), passenger voice signal at the corresponding boarding position (i.e., including passenger voice signal at the corresponding boarding position before receiving a collision occurrence signal and passenger voice signal at the corresponding boarding position after receiving a collision occurrence signal), and vehicle location information at the time of receiving the collision occurrence signal to a control server (70) via a network (60).
- passenger boarding position information i.e., including passenger boarding position information before receiving a collision occurrence signal and passenger boarding position information after receiving a collision occurrence signal
- passenger voice signal at the corresponding boarding position i.e., including passenger voice signal at the corresponding boarding position before receiving a collision occurrence signal and passenger voice signal at the corresponding boarding position after receiving a collision occurrence signal
- vehicle location information
- a network (60) may mean a connection structure that enables information exchange between a vehicle (10) and a control server (70).
- the network (60) may have any structure as long as it allows information exchange between the vehicle (10) and the control server (70).
- the control server (70) can receive information on the boarding location of a passenger, information on the current location of the vehicle (10), and a voice signal of the passenger from the vehicle (10) when an accident such as a collision occurs.
- the control server (70) can more accurately determine the number of passengers inside the vehicle at the time of a vehicle collision, whether the number of passengers has changed before and after the accident, the status of the passengers, etc. based on the received passenger boarding location information, the current location information of the vehicle (10), and the passenger's voice signal. As a result, the control server (70) can instruct a quicker and more accurate response to the vehicle collision that has occurred.
- the senor (20), the vehicle controller (30), the voice processing device (40), and the emergency rescue request device (50) can be collectively referred to as the vehicle control system.
- Figure 4 is an internal configuration diagram of the voice processing device (40) illustrated in Figure 1.
- the voice processing device (40) may include a microphone (41), a memory (42), a communication unit (43), and a processor (44).

- the microphone (41) can detect vibration of air caused by the voice and generate a voice signal, which is an electrical signal corresponding to the vibration, based on the detection result.
- the microphone (41) can receive voices of passengers located in the vehicle (10) and convert the voices of the passengers into voice signals, which are electrical signals.
- the microphone (41) may include a plurality of microphones arranged to form an array, and each of the plurality of microphones may generate a voice signal in response to a voice.
- the voice signals generated from each of the plurality of microphones may have a phase difference (or time delay) from each other.
- the microphone (41) may be installed in the center fascia in the vehicle (10).
- the center fascia may mean a control panel portion between the driver's seat and the passenger's seat among the dashboards.
- the voice processing device (40) includes a microphone (41) and directly generates a voice signal related to the voices of passengers using the microphone (41).
- the microphone may be configured externally, separate from the voice processing device (40). That is, the voice processing device (40) may receive a voice signal from a separately configured microphone and process or utilize the received voice signal. For example, the voice processing device (40) may generate a separate voice signal from a voice signal received from a separate microphone.
- the voice processing device (40) includes a microphone (41).
- the memory (42) can store data necessary for the operation of the voice processing device (40).
- the memory (42) can include at least one of a non-volatile memory and a volatile memory.
- the memory (42) may store an identifier corresponding to each sound source location (i.e., a passenger's boarding location) within the vehicle (10).
- the identifier may be data for distinguishing the sound source location. Since each of the sound source locations corresponds to each passenger, each passenger may be distinguished using an identifier corresponding to the sound source location. For example, a first identifier indicating a first sound source location may indicate a first passenger. From this perspective, an identifier corresponding to each sound source location within the vehicle (10) may also function as a passenger identifier for identifying each passenger.
- the identifier may be entered via an input device (e.g., a touch pad; not shown) of the voice processing device (40).
- an input device e.g., a touch pad; not shown
- the memory (42) may store boarding position information related to the boarding position (i.e., sound source position) of each passenger, and voice signals (e.g., separate voice signals) associated with the voices of each passenger.

- the processor (44) can process voice signals generated by the microphone (41). For example, the processor (44) can convert an analog type voice signal generated by the microphone (41) into a digital type voice signal and process the converted digital type voice signal. In this case, since the type of the signal (analog or digital) is changed, in the description of embodiments of the present invention, the digital type voice signal and the analog type voice signal are described interchangeably.
- the processor (44) may process the voice signal generated by the microphone (41) to extract (or generate) a voice signal (i.e., which may be a separate voice signal) associated with the voice of each passenger. According to embodiments, the processor (44) may generate a separate voice signal associated with the voice of the passenger located at each sound source location (i.e., the boarding location of the passenger). The separate voice signal may be in the form of voice data or text data.
- the processor (44) can determine the sound source locations of the passengers' voices (i.e., the boarding locations of the passengers) by using the time delay (or phase delay) between the separate voice signals. For example, the processor (44) can determine the relative locations of the sound sources (i.e., the relative locations of the passengers).
- the processor (44) can classify components of a voice signal by sound source location and generate a separate voice signal associated with a voice spoken at each sound source location using the classified components corresponding to each sound source location. For example, the processor (44) can generate a first separate voice signal associated with the voice of the first passenger based on the sound source location of the voices.
- the processor (44) may match and store sound source location information (i.e., passenger boarding location information) indicating the determined sound source location with a separated voice signal.
- the processor (44) may match and store in the memory (42) a first separated voice signal associated with the voice of the first passenger and first sound source location information indicating the sound source location of the voice of the first passenger.

- the processor (44) when the processor (44) receives vehicle status information (particularly, a collision occurrence signal) from the vehicle controller (30), the processor (44) may utilize the vehicle status information (particularly, a collision occurrence signal) as a trigger signal. That is, when the processor (44) receives the collision occurrence signal (i.e., the trigger signal), the processor (44) may output passenger boarding position information and passenger voice signal (i.e., a separate voice signal) at the corresponding boarding position in response thereto. At this time, the passenger boarding position information may include passenger boarding position information before receiving the collision occurrence signal (i.e., the trigger signal) as described above and passenger boarding position information after receiving the collision occurrence signal (i.e., the trigger signal).

- the processor (44) can receive the vehicle location information at the time of the vehicle collision (i.e., at the time of receiving the collision occurrence signal) from the vehicle controller (30). Accordingly, the processor (44) can output the vehicle location information at the time of receiving the collision occurrence signal (i.e., the trigger signal) together with the passenger's boarding location information and the passenger's voice signal at the corresponding boarding location.
- the above passenger boarding location information, passenger voice signal, and vehicle location information may be transmitted to the control server (70) through the emergency rescue request device (50) after being authorized to the vehicle controller (30), or may be directly authorized to the emergency rescue request device (50) and transmitted from the emergency rescue request device (50) to the control server (70).
- the processor (44) can analyze the separated voice signal associated with the voice spoken at each sound source location to determine the height and timbre of the separated voice signal, and determine whether the passenger at the sound source location is a child passenger based on the determined height and timbre.
- a child may mean a young child from 1 year old to 6 years old. If the processor (44) determines that the passenger is a child passenger, the processor (44) can output identification information indicating that the passenger at the sound source location is a child passenger. Of course, if the processor (44) determines that the passenger at the sound source location is an adult passenger, the processor (44) can output identification information indicating that the passenger is an adult passenger.
- the processor (44) can transmit identification information indicating that the passenger is a child to the control server (70).
- the processor (44) can transmit identification information indicating that the passenger is a child to the control server (70) via the emergency rescue request device (50).
- control server (70) When identification information indicating a child passenger is transmitted to the control server (70), the control server (70) can know that there is a child passenger among the passengers, and thus can issue a more accurate response order for the rescue of children as well as adults.
- processor (44) or voice processing device (40) described in this specification may be implemented in the form of a program executable by a computing device.
- the processor (44) may execute an application stored in the memory (42) and perform operations corresponding to instructions that instruct specific operations according to the execution of the application.

- the voice of each passenger in each boarding position may be collected in advance before the vehicle starts driving, and the voice of each passenger may be collected periodically after the vehicle starts driving.
- the voice processing device (40) generates a voice signal associated with the voices of the passengers being collected (S20).
- the voice signal is a signal associated with voices spoken during a specific period of time, and may be a signal representing the voices of each of the multiple passengers.
- the voice processing device (40) determines the sound source location of each of the voices of the passengers from the voice signals associated with the voices of multiple passengers, and performs sound source separation based on the sound source location, thereby extracting (or generating) a separated voice signal associated with the voice of each of the passengers from the voice signal.
- the voice processing device (40) may generate a first separated voice signal associated with the voice of the first passenger uttered at a first sound source location (i.e., the boarding location of the passenger) based on the voice signal.
- the first separated voice signal may have the highest correlation with the voice of the first passenger among the voices of the passengers.
- the voice processing device (40) generates sound source location information (i.e., passenger boarding location information) indicating the sound source location of the voice of each of the passengers (i.e., the boarding location of the passenger) by using the time delay (or phase delay) between the voice signals associated with the voices of each of the passengers.
