Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
Referring to fig. 1, a flow chart of steps of an embodiment of a method for controlling an entertainment system of a vehicle according to the present application is shown, which may specifically include the following steps:
The vehicle information comprises control information of the vehicle and radar information acquired by a radar preset on the vehicle.
For example, the present application proposes a control method of an entertainment system of a vehicle, which is based on determining a current scene of a driver of the vehicle based on vehicle information, and a radar may be pre-installed on the vehicle for measuring thoracic vibrations of the driver, due to vital signs of the driver, for example, including: heartbeat, respiration, and the like can generate certain thoracic vibration, but for the condition that a driver sends out voice information, the influence caused by the normal vital signs can be ignored, the radar can be arranged right behind a driver seat or right in front of the driver, for example, a 79GHz radar can be used for acquiring vibration displacement in a micron level. According to the method, thoracic vibration is acquired in real time, meanwhile, control information on a CAN bus is acquired to be used as control information, whether a driver is controlling a vehicle or not is eliminated in combination, and then radar information acquired by an auxiliary radar determines whether the driver of the vehicle sends voice information or not, for example, when the driver makes a call or chats with other passengers in the vehicle, the voice volume of an entertainment system of the vehicle is adjusted correspondingly, so that voice interaction of personnel is prevented from being influenced.
And 102, under the condition that the voice information sent by the driver is determined, analyzing the voice information by utilizing a preset voice recognition strategy according to the vehicle information so as to determine whether to adjust the entertainment system.
For example, when it is determined that the driver of the vehicle has the output of the voice information through step 101, it is further required to distinguish the content of the voice information, that is, determine whether the driver interacts with the entertainment system, for example, sing along with music played by the entertainment system, and at this time, the volume of the entertainment system does not need to be adjusted; conversely, when the driver chats with other passengers in the vehicle, the playing volume of the entertainment system needs to be reduced, for example, to a lower preset volume value, so as not to affect the voice interaction between the driver and the passengers.
And 103, under the condition that the adjustment of the entertainment system is determined, adjusting the volume of the entertainment system to a preset volume value.
For example, a lower volume value can be preset as a preset volume value, or the volume is directly adjusted to zero, so that the mute mode better improves the experience of the driver.
In summary, according to the technical scheme provided by the application, whether a driver of a vehicle sends voice information or not is determined according to acquired vehicle information, wherein the vehicle information includes control information of the vehicle and radar information acquired by a radar preset on the vehicle; under the condition of meeting a first preset condition, analyzing the voice information by using a preset voice recognition strategy according to the vehicle information to determine whether to adjust the entertainment system; and in the case that the adjustment of the entertainment system is determined, adjusting the volume of the entertainment system to a preset volume value. Therefore, thoracic cavity vibration of a driver during speaking CAN be monitored through a radar arranged behind a seat or in front of the driver, and whether a voice recognition function needs to be started or not is judged by combining operation signals for the vehicle, which are recognized from a CAN (controller area network) signal, so that the volume of an entertainment system of the vehicle is adaptively controlled; meanwhile, the high background hardware and service maintenance cost caused by long-time voice recognition is reduced.
Referring to FIG. 2, a flow chart of steps of an embodiment of a method for controlling an entertainment system of a vehicle of the present application is shown, the method further comprising, prior to step 101, the steps of:
and 104, acquiring the vehicle information under the condition that the vehicle is powered on and the entertainment system is started.
For example, when the vehicle is powered on, for example, during driving, after the driver turns on the entertainment system, the vehicle information is acquired in real time, so as to accurately judge the current scene where the driver is located.
Referring to fig. 3, which is a flowchart illustrating specific steps of an embodiment of a method for controlling an entertainment system of a vehicle according to the present application, the step 101 of determining whether a driver of the vehicle utters voice information according to acquired vehicle information includes the following steps:
For example, whether vibration caused by abnormal vital signs, such as vibration except heartbeat or respiration, exists or not is determined according to thoracic vibration information of the driver acquired by the radar, and the vibration larger than a preset vibration amplitude is judged by the vibration amplitude to be used as first vibration. If the first vibration does not exist, the driver does not send out voice information, namely the first preset condition is not met; if there is a first vibration, it may indicate that the driver uttered a voice message, and therefore, it needs to be further determined by combining the control information, that is, performing the following operation of step 1012, so as to eliminate the influence of the control operation of the vehicle on the radar information.
In step 1012, in the case where it is determined that the first vibration exists, it is determined whether the driver utters a voice message based on the control information.
For example, whether the control operation on the vehicle exists at the current moment is determined according to the control information, whether the control operation can affect the radar acquisition signal is analyzed, namely possible influencing factors are eliminated, and whether the driver sends out voice information is accurately determined.
It should be noted that, the control information and the radar information are obtained simultaneously, and when the radar information is detected and determined to have vibration except for normal vital signs, the control information is used to detect whether there is control operation on the vehicle at the same time, so as to eliminate possible influence on the radar signal.
As shown in fig. 4, this step may further include the following sub-steps:
In step 10122, in the case of the control operation, it is determined whether the control operation meets a first preset condition.
Wherein the first predetermined condition is indicative of the magnitude and/or frequency of the control operation being within a predetermined range of influence on the radar information.
For example, in the case that it is determined that the first vibration exists, which may be caused by the driver operating the vehicle, it needs to be distinguished by combining with the control information, that is, it is determined whether the control operation can affect the radar information, when the magnitude and/or frequency of the control operation is within the influence range, the radar information is affected, such as noise of the engine, wind noise, and the like, and when the control operation meets the first preset condition, the step 10124 is performed, which indicates that the obtained radar information is not the voice information sent by the driver; otherwise, the driver utters the voice message, that is, the operation of step 10123 is performed to further control the volume.
In step 10124, it is determined that the driver does not send out the voice message in the case where the control operation meets the first preset condition.
Referring to fig. 5, which shows a flowchart illustrating specific steps of an embodiment of a method for controlling an entertainment system of a vehicle according to the present application, in the case that a first preset condition is met, analyzing voice information according to vehicle information and using a preset voice recognition strategy to determine whether to adjust the entertainment system according to the first preset condition in step 102 includes the following steps:
The second preset condition comprises the condition that the similarity between the voice information and the playing content of the entertainment system is greater than a preset threshold value.
For example, after step 101, it is determined that there is actually voice information uttered by the driver, and further recognition of the voice content may be performed to exclude the situation that the driver interacts with the entertainment system, for example, humming along with the entertainment system, that is, determining according to similarity of the voice information, when the similarity is greater than a preset threshold, for example, it may be set to be 0.85, and when the similarity between the voice information uttered by the driver and the playing content of the entertainment system is greater than 0.85, it indicates that the driver is humming, without operating the entertainment system, and the playing volume of the entertainment system is maintained; otherwise, the voice information is sent out by the driver, the volume of the entertainment system needs to be reduced, and the adaptive in-vehicle environment is provided for the driver. The specific setting of the preset threshold is not limited in the present application.
And 1022, determining not to adjust the entertainment system under the condition that the voice information meets the second preset condition.
And 1023, determining to adjust the entertainment system under the condition that the voice information does not meet the second preset condition.
