Detailed Description
In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description.
At present, a scene that no person is on the vehicle and a driver needs to control the vehicle outside the vehicle is often encountered, for example, when the hands of the driver are occupied by articles, a physical key or a mobile terminal device is inconvenient to use, but a trunk of the vehicle needs to be opened at the moment; when a driver works in front of a vehicle, if the environment of the vehicle is too dim, the vehicle lamp is required to be illuminated, but the vehicle lamp is required to be turned on by the driver entering the vehicle, and the process is complex; when a driver charges the vehicle outside the vehicle, but forgets to open the charging port, the driver needs to enter the vehicle to open the charging port or open the charging port through key operation of a key, and the charging port is inconvenient for the driver to control the vehicle outside the vehicle, so that convenience is low.
One of the core ideas of the embodiment of the invention is that the function control of the vehicle outside the vehicle is realized by establishing the voice control of the personnel outside the vehicle, so that a driver can conveniently realize the control of the vehicle when the driver is outside the vehicle, and the situation that the vehicle cannot be controlled by adopting a physical key or mobile terminal equipment because both hands are occupied can not occur.
Referring to fig. 1, a flowchart illustrating steps of a vehicle-based voice communication method of the present invention may specifically include the steps of:
step 101, receiving a voice request sent by an outside person under the condition that no person exists in the vehicle and the vehicle-to-machine system is in a working state;
The outside personnel need to carry out voice control to the vehicle, and the premise of voice control is that the vehicle machine system is in a working state, namely when the voice control of the outside personnel is established, the vehicle machine system is in the working state though no person is in the vehicle, so that the vehicle machine system in the working state can support the function related to voice control to receive the voice request sent by the outside personnel so as to respond to the received voice request.
The voice request received by the vehicle-mounted system in the working state can be generated based on a vehicle external voice signal sent by a person outside the vehicle relative to the vehicle. In practical application, the vehicle can be controlled to collect the voice signal of the person outside the vehicle based on the position of the person outside the vehicle relative to the vehicle by adopting the function related to voice control through the vehicle-to-machine system so as to determine the voice request corresponding to the collected voice signal.
Specifically, determining the voice request corresponding to the collected voice signal can be achieved by performing voice recognition on the collected voice signal outside the vehicle through the vehicle-to-vehicle system, and mapping and/or associating the recognized voice with the related request. The embodiments of the present invention are not limited in this regard.
As an example, the collected off-vehicle voice signal may be "open window", "window lower some", "no lift in, window lower a little more", etc., and the current voice request corresponding to the off-vehicle voice signal may be "open window".
And 102, responding to the voice request through the vehicle-to-machine system, and controlling the vehicle to execute corresponding operation.
After the voice request sent by the personnel outside the vehicle is received through the vehicle machine system in the working state, the received voice request can be responded, and the function control of the personnel outside the vehicle on the vehicle can be completed.
In a preferred example, after controlling the vehicle To perform a corresponding operation according To a voice request corresponding To a voice signal outside the vehicle, the vehicle system may further generate a TTS (Text To Speech) report for voice feedback based on completion of the vehicle control To inform a person initiating the voice control that voice communication between the person outside the vehicle and the vehicle is currently achieved based on a control result of the request for the vehicle.
It should be noted that, the voice request that the vehicle system in the working state receives and can respond to may be a request related to controlling the vehicle, which is not limited in this embodiment of the present invention.
As an example, the voice request received by the vehicle system from an off-board person may be a trunk control request, where the opening or closing of the trunk may be controlled by the vehicle system in response to the trunk control request.
As another example, the voice request received by the vehicle system may be a vehicle lamp lighting control request, and at this time, the vehicle system may respond to the vehicle lamp lighting control request to control on or off of the vehicle lamp and/or adjust the light level of the vehicle lamp, where the vehicle lamp capable of being adjusted by the vehicle system may include a front headlight (including a high beam and a low beam), a fog lamp, a daytime running light, and the like, which is not limited in this embodiment of the present invention.
As yet another example, the voice request sent by the person outside the vehicle and received by the vehicle system may be a charging port control request, where the opening or closing of the charging port of the vehicle may be controlled by the vehicle system in response to the charging port control request, where the charging port of the vehicle capable of being controlled may include a fast charging port and a slow charging port.
In the invention, when no personnel are in the vehicle and the vehicle-mounted system is in a working state, the voice request sent by the personnel outside the vehicle is received, the received voice request can be generated based on the voice signal sent by the personnel outside the vehicle relative to the vehicle, and at the moment, the vehicle can be controlled to execute corresponding operation by responding to the voice request through the vehicle-mounted system in the working state. By establishing voice control of the personnel outside the vehicle, the function control of the personnel outside the vehicle on the vehicle is realized, and the situation that the physical key or the mobile terminal equipment cannot be adopted to control the vehicle because both hands are occupied is avoided.
Referring to fig. 2, a flowchart illustrating steps of another vehicle-based voice communication method of the present invention may specifically include the steps of:
step 201, detecting personnel outside the vehicle and waking up the vehicle system under the condition that the vehicle system is in a standby state;
in the invention, the outside personnel need to carry out voice control on the vehicle, and the premise of the voice control is that the vehicle system is in a working state, but if no personnel exist in the vehicle, the vehicle system can be in a standby or dormant state and cannot support the voice function, the awakening operation is firstly required to be carried out on the vehicle, so that the awakened vehicle can support the function related to the voice control.
Specifically, when the vehicle system in the standby or sleep state detects a person outside the vehicle, the vehicle may be awakened so that the vehicle system in the standby state enters the working state.
Specifically, the vehicle wakes up the vehicle system, the position of the person outside the vehicle relative to the vehicle can be detected, the vehicle can have microphones located inside and outside the vehicle, and the vehicle system in a standby state can be brought into a working state after the vehicle system is waken up based on the position of the person outside the vehicle relative to the vehicle.
In practical application, in order to ensure the safety of the vehicle, the person outside the vehicle detected by the vehicle may be the vehicle owner or the person outside the vehicle authorized by the vehicle owner, that is, the vehicle can be awakened when the person outside the vehicle having control right to the vehicle is detected.
In a specific implementation, for a judging mode that an external person is a car owner or a person authorized by the car owner, in a mode, the external person can be authenticated through voiceprint, specifically, a car machine system can prestore voiceprint features corresponding to the car owner or the person authorized by the car owner, the voiceprint features can be extracted after the voice of the external person is collected, the extracted voiceprint features are compared with the prestored voiceprint features, and when the extracted voiceprint features are consistent with the prestored voiceprint features, the external person can be judged to have control right on the car.
In another way, the vehicle owner or the person outside the vehicle authorized by the vehicle owner can carry the identification device authenticated by the vehicle owner, such as a physical key, a virtual key contained in the mobile terminal device, and the like, so that the person carrying the identification device can wake up the vehicle and realize voice control on the vehicle, and the control right on the vehicle is not limited to the vehicle owner only.
The position of the person outside the vehicle relative to the vehicle can comprise the direction of the person outside the vehicle relative to the vehicle and the distance of the person outside the vehicle relative to the vehicle, and the mode of detecting the position of the relative vehicle can be realized by receiving radio frequency energy difference information or camera identification information returned by the person outside the vehicle and determining the distance and the direction of the person outside the vehicle relative to the vehicle.
In practical application, the vehicle may have at least one bluetooth antenna, and when the vehicle owner or the person outside the vehicle authorized by the vehicle owner carries the identification device, at this time, radio frequency operation may be performed on the carried identification device by the at least one bluetooth antenna, that is, a radio frequency signal may be sent, and the identification device with a radio frequency function may return radio frequency energy to the bluetooth antenna that sends the radio frequency signal, so at this time, the vehicle may obtain radio frequency energy returned by each bluetooth antenna based on the identification device, and since the radio frequency energy received by each antenna is different, the distance and direction of the person outside the vehicle relative to the vehicle may be determined according to the difference of the received radio frequency energy, that is, the difference information between the received radio frequency energy and the received difference information; the vehicle can be further provided with at least one camera, the camera is used for identifying the personnel outside the vehicle to obtain image information, the image information can be acquired based on the cameras in different directions of the vehicle, and at the moment, the distance and the direction of the personnel outside the vehicle, which are identified in the image information, relative to the vehicle can be determined based on the acquisition range of the camera and the direction corresponding to the camera.
At this time, the vehicle can be awakened under the condition that the distance between the person outside the vehicle and the vehicle is detected to be smaller than a preset distance threshold value, namely, the vehicle-to-machine system is started, and preparation for voice awakening and voice recognition is made.
Step 202, acquiring an off-board voice signal of an off-board person based on the position of the off-board person relative to the vehicle;
under the condition that the vehicle is awakened, the vehicle-mounted system in the working state can support functions related to voice control, and at the moment, the off-board voice signals of the off-board personnel can be collected.
The position of the vehicle exterior personnel relative to the vehicle can comprise the direction of the vehicle exterior personnel relative to the vehicle and the distance of the vehicle exterior personnel relative to the vehicle, and the vehicle exterior voice signals can be acquired based on the direction of the vehicle exterior personnel relative to the vehicle, so that corresponding voice requests can be generated according to the acquired vehicle exterior voice signals.
In the process of collecting the voice signals outside the vehicle, the voice signals belonging to the target voice zone can be collected, namely, the target voice zone needs to be determined at first. The method can be specifically characterized in that a target voice zone is determined according to the direction of an external person relative to the vehicle, and an external voice signal positioned in the target voice zone is collected.
In practical application, the vehicle may have a microphone located outside the vehicle body, and the microphone may be an external microphone array, so that the mode of determining the target sound area may utilize the bluetooth antenna to determine the direction of the external person relative to the vehicle, and combine with beam forming performed by the microphone array to implement positioning of the sound source.
Specifically, the direction of the person outside the vehicle can be used as the formulated direction in the beam forming process, the microphone array outside the vehicle is used as the formulated direction according to the direction of the person outside the vehicle relative to the vehicle, and the range area pointed by the beam is used as the target sound area, so that the microphone array outside the vehicle is pointed to the person outside the vehicle with identity authentication, and only the voice signals of the person outside the vehicle are collected.
And 203, controlling the vehicle to execute corresponding operation according to the collected external voice signal.
After the vehicle-mounted system in the working state collects the external voice signals and generates corresponding voice requests based on the collected external voice signals, the voice requests can be responded, and the function control of the personnel outside the vehicle on the vehicle can be completed.
In a preferred example, after the voice signal of the person outside the vehicle is collected by directing the microphone array outside the vehicle to the person outside the vehicle, a voice feedback signal may be sent to the person outside the vehicle to initiate voice control to inform the result, so as to realize voice communication between the person outside the vehicle and the vehicle.
Specifically, the vehicle may have a speaker located on the body outward, and the content of the voice feedback may be played to an off-board person through the speaker.
In an alternative example, in the process of collecting the voice signal of the person outside the vehicle and playing the content of the voice feedback to the person outside the vehicle, the audio communication link established in the vehicle system can be realized by an audio communication link established in the vehicle system, and the established audio communication link can comprise an uplink communication link and a downlink communication link, namely, when the voice signal of the person outside the vehicle is collected, the collected voice signal can be used as an input interface of the system through a microphone positioned outside the vehicle body, and the collected voice signal is used as an uplink signal to be input into the system to be subjected to noise reduction, echo cancellation, human voice enhancement, signal amplification and other processes to obtain the voice content so as to generate a corresponding voice request; when the content of the voice feedback is played to the personnel outside the vehicle, a loudspeaker positioned on the vehicle body and facing outwards can be used as an output interface of the system, TTS (time to live) for voice feedback generated after the vehicle control is completed is used as a downlink signal, and the output interface is used for outputting the voice broadcast to the personnel outside the vehicle.
In a preferred example, the off-board personnel that are able to control the vehicle may be other off-board personnel in addition to or in addition to the person authorized by the vehicle owner, but such off-board personnel are able to control the vehicle with rights other than the person authorized by the vehicle owner or by the vehicle owner. The vehicle can also receive voice requests of other people after detecting the positions of the other people outside the vehicle relative to the vehicle and waking up the vehicle system, but after receiving the voice requests, the vehicle needs to judge whether the other people outside the vehicle have control authority of the content requested by the voice, if the vehicle does not have the control authority of the content requested by the voice, the vehicle system only receives the voice requests but does not respond to the voice requests, and the vehicle system can also send voice feedback contents such as 'not having the control authority' to the other people outside the vehicle through a loudspeaker arranged on the vehicle body.
As an example, when the vehicle system receives a door unlocking request sent by a person outside the vehicle except the vehicle owner or authorized person passing through the vehicle owner, it is determined that the person outside the vehicle which initiates the request does not have control authority on the door, and at this time, the person outside the vehicle can be notified of the voice feedback contents such as "you cannot unlock the door", "does not have door unlocking authority", and the like; as yet another example, when the vehicle system receives a vehicle movement request sent by an external person other than the vehicle owner or an authorized person passing through the vehicle owner, for example, the vehicle system may determine that the external person currently sending the request has movement control authority for the vehicle in order to prevent the parking position of the current vehicle from interfering with others, and may respond to the vehicle movement request and control the vehicle to move a preset distance in a preset direction, so as to complete corresponding control for the vehicle, and may report the content of voice feedback such as "the operation has been completed" to the external person through a speaker located outside the vehicle body after the completion of the corresponding control for the vehicle.
According to the invention, the voice control of the personnel outside the vehicle is established, so that the function control of the personnel outside the vehicle on the vehicle is realized, and the situation that the vehicle cannot be controlled by adopting a physical key or a mobile terminal device because both hands are occupied is avoided.
