Description

Vehicle-mounted sound box control system and vehicle-mounted sound box
Technical Field
The invention relates to the technical field of vehicle-mounted peripheral equipment, in particular to a vehicle-mounted sound box control system and a vehicle-mounted sound box.
Background
With the development of the automobile industry, the types of peripheral devices connected with automobiles are increasing. Vehicle-mounted sound boxes are increasingly appearing in people's lives as a common vehicle-mounted peripheral device.
In order to make the car-mounted sound box more intelligent, in the prior art, one way is to assemble more parts on the car-mounted sound box, such as a wireless sensor connected to a mobile phone, a voice receiving module for receiving voice commands of passengers, a voice judging module, and the like, so that the car-mounted sound box can collect more information, and then perform more intelligent operation according to the collected information. However, due to the addition of many parts, the price of the peripheral equipment is significantly increased, and with the increase of the parts, the power consumption of the vehicle-mounted sound box is also increased, which increases the burden of the vehicle, and further, the functions of the various parts on the vehicle-mounted sound box coincide with the functions of the vehicle, resulting in functional waste.
Generally, a plurality of information acquisition devices are arranged in an automobile, and the acquired specific data can be divided into a plurality of types, and generally include HMI (Human Machine Interface) system data, original automobile body data and cloud communication data, wherein the HMI system data includes but is not limited to files stored in a vehicle-mounted entertainment system, information acquired by information acquisition equipment such as a control command, instrument display, a camera and a radar acquired from the vehicle-mounted entertainment system, and the like; the original vehicle body data includes, but is not limited to, original vehicle body data of vehicle speed, driving mileage, brake, engine speed, steering wheel angle, temperature of each part, engine torque, accelerator opening, brake pedal, gear lever position, etc.; the cloud communication data includes, but is not limited to, control command data of remote mobile devices such as mobile phones, information service data provided by platform service providers such as weather information, road condition information, map information, song information, video information, broadcast information, and the like.
In order to reduce the number of parts on the peripheral equipment and to make the peripheral equipment more intelligent, the peripheral equipment, such as a car-mounted sound box, generally utilizes the original information of the vehicle as much as possible.
In order to utilize the information of the vehicle, one mode is that the vehicle-mounted sound box is directly connected with some functional components on the vehicle, such as some sensors, and obtains the relevant information collected by the sensors on the vehicle, and utilizes the functional components on the vehicle to reduce the cost per se. The function of the vehicle-mounted sound box under the design can be single, if the functional components of the vehicle are used more, the vehicle-mounted sound box is required to be connected with the plurality of functional components on the vehicle, the assembly is complex, and the control logic is complex due to messy information.
In another mode, the vehicle-mounted sound box is connected with an OBD interface of the vehicle, and the original vehicle body data is read through the OBD interface. However, the OBD interface is a diagnostic interface of the vehicle, the acquired information is the original vehicle body data, the interface belongs to a safety interface, and if the vehicle-mounted sound box is directly connected with the OBD interface, if program confusion occurs in the peripheral equipment when the peripheral equipment is connected for a long time, the safety of the vehicle itself may be affected through the OBD interface, and potential safety hazards exist. In addition, the OBD interface is only one, when the vehicle-mounted sound box is connected with the OBD interface, other peripheral equipment can not obtain the vehicle information through the way, and the popularization of the vehicle-mounted peripheral equipment on a vehicle is not facilitated.
Automobile manufacturers generally place OBD interfaces in relatively concealed locations, such as below the fuse box, below the storage box, and below the center console. After the vehicle-mounted sound box is connected with the OBD interface, the vehicle-mounted sound box has the defect that a flat cable circuit is complex or peripheral equipment cannot be arranged.
In another method, the vehicle-mounted speaker is connected to an HMI system of the vehicle, such as a center control display, through a USB interface, but this method, like the OBD interface, can only obtain one-sided data of the HMI system data, and cannot obtain the original vehicle body data and the HMI system data at the same time.
In addition, when the existing peripheral equipment is remotely controlled, a signal transmitted remotely is generally received through wireless communication setting on the peripheral equipment, but the signal is generally weak, and the reliability of control information transmission cannot be ensured.

Fig. 1 is a system block diagram of a vehicle-mounted sound box control system according to an embodiment of the present invention, and fig. 2 is a schematic diagram of a connection relationship between a vehicle-mounted connector and a vehicle-mounted sound box in the vehicle-mounted sound box control system according to the embodiment of the present invention. As shown in fig. 1 and fig. 2, the vehicle-mounted sound box control system according to the embodiment of the present invention includes a vehicle-mounted connector 10 and a vehicle-mounted sound box 20 in data connection with the vehicle-mounted connector 10, the vehicle-mounted connector 10 is in data connection with a vehicle network 30, the vehicle-mounted connector 10 includes a first processing unit 11, a first data transmission module 12 and a first security module 13, and the first processing unit 11 is electrically connected with the first data transmission module 12 and the first security module 13, respectively. The vehicular speaker 20 includes a second processing unit 21, a second data transmission module 22, a second security module 23, and an execution module 25, wherein the second processing unit 21 is electrically connected to the second data transmission module 22, the second security module 23, and the execution module 25, respectively. The vehicle-mounted sound box 20 is in data connection with the vehicle-mounted connector 10 through the second data transmission module 22 and the first data transmission module 12, the vehicle-mounted connector 10 is authenticated with the vehicle-mounted sound box 20 through the first safety module 13 and the second safety module 23, and after authentication is successful, the vehicle-mounted sound box 20 is in data connection with the vehicle-mounted connector 10 and performs data interaction with the vehicle network 30 through the vehicle-mounted connector 10.
As shown in fig. 2, in the embodiment, since the vehicle-mounted connector 10 is connected to the vehicle network 30, after the vehicle-mounted connector 10 authenticates the vehicle-mounted sound box 20, the vehicle-mounted connector 10 can interact the information required by the vehicle-mounted sound box 20 or the sent information with the HMI system data, the cloud communication data and the original vehicle body data according to the communication protocol of the vehicle network 30, and it is not necessary to connect the vehicle-mounted sound box 20 to a plurality of components of the vehicle. Further, since the car audio 20 needs to be authenticated with the car connector 10 to enable data connection, it is possible to ensure data security.
More specifically, the vehicle-mounted connector 10 may be in data connection with a vehicle CAN network, and preferably, the vehicle CAN network may be the same sub-CAN network connected with the HMI system and the wireless transmission module, that is, the vehicle-mounted connector 10, the HMI system 40 and the wireless transmission module 50 are connected with the same sub-CAN network.
According to the control architecture of the vehicle, the vehicle may have a plurality of sub-CAN networks such as CAN I, CAN II, CAN III, CAN IV, etc., such as body control CAN, diagnostic CAN, comfort CAN, power CAN, entertainment CAN, etc., each line is connected through a gateway, and the information transmission control unit of the vehicle network 30, such as a gateway, receives data information transmitted by each CAN line and transmits information required by the vehicle-mounted connector 10 to the vehicle-mounted connector 10 through the CAN line. The vehicle-mounted connector 10 described in this patent CAN be connected to the HMI system 40 and the wireless transmission module 50 in the same sub-CAN network, in this sub-network, the vehicle-mounted connector 10 CAN have the same transmission rate as the HMI system 40 and the wireless transmission module 50 in the vehicle network, the transmission rates between them are relatively fast, and CAN receive data in other CAN networks transmitted by a gateway through a CAN network protocol, or send data to other CAN networks through the gateway, and will not interfere with original vehicle body data in other sub-CAN networks, such as data of a power system and a diagnostic system.
In other embodiments, the vehicle-mounted connector 10 may also be connected to a vehicle ethernet network, in particular to an information transmission control unit, such as a switch, within the vehicle ethernet network. According to the network protocol of the vehicle ethernet, the switch may transmit information required for the car audio amplifier 20 to the car connector 10, or transmit request information for the car audio amplifier 20 to other original car devices through the switch.
Since the vehicle-mounted connector 10 is connected to the vehicle network 30, after the vehicle-mounted connector 10 authenticates the vehicle-mounted sound box 20, the vehicle-mounted connector 10 CAN interact information required by the vehicle-mounted sound box 20 or sent information with HMI system data, cloud communication data and original vehicle body data in a message form in the CAN bus protocol, and does not need to connect the vehicle-mounted sound box 20 with a plurality of components of the vehicle. Further, since the car speaker 20 needs to be authenticated with the car connector 10, the data connection can be realized, which can ensure the security of data. Further, since the car speaker 20 is connected to the vehicle network 30 through the car connector 10, the data transferred from the car speaker 20 to the vehicle network 30 is controlled by the car connector 10, and the car connector 10 determines the data to be interacted sent by the car speaker 20, so as to prevent the car speaker 20 from affecting the vehicle network 30.
Further, the second processing unit 21 in the car speaker 20 sends request information containing data interaction type and data interaction content to the first processing unit 11 through the second data transmission module 22 and the first data transmission module 12, and the first processing unit 11 transmits data required by the car speaker 20 to the car speaker 20 according to the request information containing data interaction type and data interaction content, and/or transmits information transmitted by the car speaker 20 to the vehicle network 30. That is, in the present embodiment, the data interaction category represents different data sources, and the data interaction content represents different data in different data sources.
In this embodiment, the data sources may be the HMI system 40, the vehicle network 30 for transmitting the original vehicle body data, and the cloud server 60, and accordingly, the data interaction types include the HMI system data, the original vehicle body data, and the cloud communication data.
In the present embodiment, the vehicle-mounted connector 10 can also be directly connected to the HMI system 40, that is, the vehicle-mounted connector 10 can interact not only with the HMI system 40 from within the vehicle network 30 but also directly with the HMI system 40. When the vehicle-mounted sound box 20 needs to interact with the HMI system 40, the first processing unit 11 enables the vehicle-mounted sound box 20 to perform data interaction with the HMI system 40 through the vehicle network 30 or directly perform data interaction with the HMI system 40 according to different data interaction contents, so as to improve the data interaction rate with the HMI system 40.
More specifically, after the in-vehicle connector 10 confirms that the in-vehicle speaker 20 is allowed to be connected by the in-vehicle connector 10 through authentication of the in-vehicle speaker 20, the in-vehicle connector 10 controls the wireless transmission module 50 of the vehicle through the vehicle network 30 to transmit information that the in-vehicle speaker is connected to the cloud server 60, and receives a remote control command transmitted from the cloud server 60 from the vehicle network 30 and transmits the remote control command to the in-vehicle speaker 20. The second processing unit 21 controls the execution module 25 to execute corresponding actions according to the received command.
In this implementation, the wireless transmission module 50 may be a module with communication function, embodied in a vehicle as a TBOX or entertainment system with communication module and a rearview mirror system.
Since the control method is performed according to the transmission channel of the vehicle network 30, the vehicle-mounted connector 10 can be considered as a part of the vehicle connected to the vehicle network 30, and even in a state where the vehicle is in a dormant state, the vehicle can be awakened through remote control according to the original dormancy awakening control strategy of the vehicle, and then the vehicle-mounted sound box 20 is controlled through the vehicle-mounted connector 10 after the vehicle is awakened, and the vehicle-mounted sound box 20 can be controlled through the vehicle network 30 remotely without any change of a program on the vehicle. This can complete wireless control, and at the same time, save the wireless transmission module of the vehicle-mounted sound box 20 itself, and with the help of the wireless communication of the vehicle, the transmission reliability of the control signal is higher. Furthermore, after the vehicle is awakened, the power supply of the vehicle can be used for supplying power for the operation of the vehicle-mounted sound box 20, so that the operation time of the vehicle-mounted sound box is prolonged.
Further, after the vehicle-mounted connector 10 passes the authentication of the vehicle-mounted sound box 20, the first processing unit 11 obtains the control parameter information of the vehicle-mounted sound box 20, converts the control parameter information and sends the control parameter information to the vehicle network 30, so that the HMI system 40 of the vehicle displays the control interface of the vehicle-mounted sound box 20; and acquiring a control command of the HMI system 40 from the vehicle network 30, and transmitting the command to the car speaker 20, and the car speaker 20 executes a corresponding action according to the received command.
After the vehicle-mounted connector 10 obtains the control parameter information of the vehicle-mounted sound box 20, the vehicle-mounted connector 10 may convert the control parameter information of the vehicle-mounted sound box 20 into a message formed according to a CAN bus protocol, and then transmit the message into the vehicle network 30, so that the HMI system 40 of the vehicle may obtain the control parameter information of the vehicle-mounted sound box 20 from the vehicle network 30, and then display a control interface on a display in the HMI system 40. The vehicle interior passenger can control the vehicle-mounted sound box 20 through the HMI system 40 of the vehicle, and does not need to contact the vehicle-mounted sound box 20, so that the operation flow is simplified, the driving experience is improved, and the vehicle interior passenger can select the placement position of the vehicle-mounted sound box 20 more flexibly.
It is to be understood that the control command may be a command obtained from a control interface, a command recognized by the HMI system in the form of a sound, an action, etc. for the car speaker 20, or an auxiliary action command transmitted by other peripheral devices. That is, the form of the command is not required, and may be obtained from the vehicle network 30 by the vehicle-mounted connector 10 and transmitted to the vehicle-mounted sound box 20.
The car connector 10 may also obtain the request information of the assisting action from other peripheral devices, and transmit the request information to the car speaker 20, and after receiving the information, the car speaker 20 controls the execution module 25 to execute the corresponding action.
In the present embodiment, the monitoring event set corresponding to the authenticated in-vehicle sound box 20 is stored in the in-vehicle connector 10. After the vehicle-mounted connector 10 is authenticated with the vehicle-mounted sound box 20 through the first security module 13 and the second security module 23, the vehicle network 30 is monitored according to the monitoring event set corresponding to the authenticated vehicle-mounted sound box 20, and when a preset event in the monitoring event set corresponding to the vehicle-mounted sound box 20 occurs, the vehicle-mounted connector 10 transmits information that the preset event has occurred to the vehicle-mounted sound box 20. In this embodiment, the monitoring event set may be pre-stored in vehicle connector 10, or after vehicle speaker 20 passes the authentication, vehicle connector 10 may obtain the monitoring event set from an external storage device such as vehicle speaker 20, a storage medium in the vehicle, or cloud server 60. Different models of car speakers 20 may correspond to different sets of monitoring events due to their different functions.
In terms of the vehicle network, the information control unit of the vehicle network may transfer data belonging to a data set to the vehicle-mounted connector 10 according to a predetermined data set according to the vehicle-mounted communication protocol. The data set may be a collection of information required for all of the in-vehicle speakers 20 connectable to the in-vehicle connector 10, and the in-vehicle connector 10 may determine the information based on information transmitted from the information control unit of the vehicle network and the connected in-vehicle speakers 20, and may transmit information that a predetermined event has occurred to the in-vehicle speakers 20 when the information belongs to a monitoring event set of the in-vehicle speakers 20 connected to the in-vehicle connector 10.
In this embodiment, the car speaker 20 controls the execution module 25 to execute a corresponding preset action according to the information that the preset event in the corresponding monitoring event set transmitted by the car connector 10 has occurred.
It should be noted that, in this embodiment, when the in-vehicle speaker 20 determines that a preset event has occurred in the event set, or a plurality of preset events have occurred, it may perform a corresponding preset action according to the condition that the preset event has occurred.
In other embodiments, after receiving the information that the preset event has occurred in the monitoring event set transmitted by the vehicle-mounted connector 10, or after the vehicle-mounted speaker 20 itself detects that a certain event has occurred, for example, after acquiring a certain information or command from the vehicle-mounted speaker 20 itself, the vehicle-mounted speaker 20 may further send data request information to the vehicle-mounted connector 10 according to its own needs to request the relevant data of each data source of the vehicle, and after receiving the request, the vehicle-mounted connector 10 requests the vehicle network 30 for the relevant information and sends the corresponding data to the vehicle-mounted speaker 20, so that the vehicle-mounted speaker 20 can perform the action more accurately with the data as a reference.
Similarly, the car audio amplifier 20 may send the assisting action request information to the car connector 10 according to its own requirement after receiving the information that the preset event has occurred in the monitoring event set transmitted by the car connector 10, or after the car audio amplifier 20 itself detects a certain event, the car connector 10 sends the request for executing the relevant action to the inside of the vehicle network 30 or other peripheral devices after receiving the request of the car audio amplifier 20, and after receiving the request, the car itself or other peripheral devices on the car may execute the corresponding requesting action to cooperate with the car audio amplifier 20 itself, so that the car audio amplifier 20 provides better service. That is, the request target of the assistance request information may be the function device of the original vehicle itself, or may be other peripheral devices connected to the vehicle-mounted connector 10 or directly connected to the vehicle.
In the vehicle-mounted connector 10, a legal interaction data set corresponding to the certified vehicle-mounted sound box 20 is also stored. When the car speaker 20 sends data request information or assistance request information to the car connector 10, the car connector 10 determines the request information, and if the request information belongs to a legal interaction data set, the car connector 10 interacts corresponding data with the vehicle network 30 according to the request information.
Within the monitoring event set and the legal interaction data set in the on-board connector 10, the events include, but are not limited to, raw vehicle body data, HMI system data, and cloud communication data. Each data set is shown in table one and table two below. It is to be understood that table one is merely exemplary and does not limit the set of events.
Table one: different monitoring event sets corresponding to different vehicle-mounted sound boxes 20 in vehicle-mounted connector 10

Table two: legal interactive data set of corresponding vehicle-mounted sound box 20 in vehicle-mounted connector 10
Figure GDA0003942503160000132
Taking the car audio amplifier (1) as an example, in the present embodiment, after the car connector 10 is authenticated and it is confirmed that the car audio amplifier (1) is connected to the car connector 10, the car connector 10 monitors the car CAN network 30 according to the monitoring event set corresponding to the car audio amplifier 20. When the vehicle-mounted connector 10 detects that the driver has a positive emotion (that is, the event three in the table one occurs) in the monitoring event set, such as happiness, joy, and the like, the vehicle-mounted connector 10 sends the information that the event three has occurred to the vehicle-mounted sound box 20, and the vehicle-mounted sound box 20 can select a song that is relatively fast, exciting, and the like and is relatively matched with the emotion of the driver at that time from the information that the event three has occurred to play.
That is, in the present invention, the second processing unit 21 of the car speaker 20 does not perform a more complicated determination on the data, such as determining whether there is a smoking in the vehicle, whether there is a shoe in the vehicle, etc., the determination may be performed by the original determination logic of the vehicle, and the car connector 10 only needs to obtain the signal in the vehicle CAN network. This can significantly reduce the complexity of the control logic of the in-vehicle speaker 20 itself, reducing the cost of the in-vehicle speaker 20.
When the request message that the vehicle-mounted connector 10 connects to the vehicle-mounted sound box 20 does not belong to the legal interactive data set, the vehicle-mounted connector 10 does not respond to the request message, and the request message cannot enter the vehicle CAN network 30, so that the vehicle-mounted fragrance 20 is prevented from modifying the original vehicle body data through the vehicle CAN network 30. It is understood that in this embodiment, the control command may also exist as an event in the monitoring event set in table one. That is, when the in-vehicle connector 10 detects a control command through the vehicle network 30, the in-vehicle connector 10 transfers the command information into the in-vehicle sound box 20.
Further, after the vehicle-mounted connector 10 receives the remote control command from the vehicle network 30, the vehicle-mounted connector 10 detects whether the connection with the vehicle-mounted speaker 20 is maintained again, and if the connection is disconnected, the vehicle-mounted connector 10 controls the wireless transmission module 50 to send the device disconnection information to the cloud server through the vehicle network 30.
That is, in the present invention, the determination process of determining whether the related event occurs according to the original data can be performed inside the vehicle, for example, the vehicle determines whether the vehicle is speeding, the emotion of the driver, etc. according to its own module. When an event defined in the network protocol occurs, it is only necessary to transmit the information to the in-vehicle connector 10 through the information transmission control unit of the vehicle network 30 according to the network protocol, the in-vehicle connector 10 determines from the monitoring event set corresponding to the in-vehicle speaker 20 connected to itself, and if the monitoring event set belongs to, the information is transmitted to the in-vehicle speaker 20. This enables the in-vehicle speaker 20 to perform corresponding operations without adding various sensors and without adding a determination logic, by applying data in the vehicle network. The cost of the vehicle-mounted sound box 20 is reduced, and the intelligent degree of the vehicle-mounted sound box 20 is improved.
Further, in the embodiment, the first data transmission module 12 and the second data transmission module 22 may be communicatively connected in a wireless manner such as wifi, radio frequency, bluetooth, BT (bit stream) and the like to implement data interaction. It CAN be understood that it CAN also be connected in a wired communication manner through interfaces such as a USB interface, a UART interface, a CAN line interface, an ethernet network interface, an LVDS interface, an HDMI interface, or an MIPI interface to implement data interaction.
Further, the first security module 13 and the second security module 23 encrypt the transmitted data and decrypt the received data to ensure the security of data communication.
Further, the vehicle-mounted connector 10 is further provided with a first power supply module 14 for supplying power to the vehicle-mounted sound box 20, the first power supply module 14 is connected to the vehicle battery 70, a second power supply module 24 is further provided in the vehicle-mounted sound box 20, and when the vehicle-mounted sound box 20 is connected to the vehicle-mounted connector 10, the vehicle-mounted connector 10 can supply power to the second power supply module 24 of the vehicle-mounted sound box 20 through the first power supply module 14.
In this embodiment, a power supply interface is disposed on the vehicle-mounted connector 10, the vehicle-mounted sound box 20 may be connected to the vehicle-mounted connector 10 through the power supply interface, and the vehicle-mounted connector 10 supplies power to the vehicle-mounted sound box 20 through the power supply interface and performs data interaction with the vehicle-mounted sound box 20.
In other embodiments, the first power supply module 14 may also be a wireless power supply device, and the car connector 10 supplies power to the car audio 20 by wireless power supply.
Further, a circuit protection module 15 is disposed on the vehicle-mounted connector 10 to protect the vehicle and the vehicle-mounted speaker 20 during power supply. The circuit protection module 15 detects the remaining power in the battery 70, and stops supplying power to the car audio 20 when the remaining power in the battery 70 is lower than a set threshold. The circuit protection module 15 detects whether the car speaker 20 has a short circuit phenomenon, and stops supplying power to the car speaker 20 when the short circuit phenomenon exists in the car speaker 20.
The following describes a control system for a car audio amplifier 20 according to an embodiment of the car audio amplifier 20.
In the first embodiment of the present invention, the car connector 10 obtains information of the state of the driver from the vehicle network, such as the driver has a positive emotion, a negative emotion, and the driver is drowsy, and transmits the state information of the driver to the car speaker 20, the car speaker 20 receives the state information of the driver transmitted by the car connector 10, and the car speaker 20 selects a preset type of song corresponding to the state of the driver for playing.
When the in-vehicle sound box 20 obtains the information that the driver is in the drowsy state from the in-vehicle connector 10, the in-vehicle sound box 20 may increase the playing volume of the in-vehicle sound box 20 while selecting the corresponding preset type of song to play.
In this embodiment, when there is no song corresponding to the current state of the driver in the song library of the car audio amplifier 20 itself, the car audio amplifier 20 sends song data request information to the car connector 10, requests the storage device of the vehicle to download the song corresponding to the current state of the driver, and the car connector 10 obtains the song of the type from the storage device of the vehicle and transfers the song to the car audio amplifier 20 for playing.
In the present embodiment, when the in-vehicle connector 10 transmits the song data request information of the in-vehicle sound box 20 to the HMI system through the in-vehicle network 30. Because of the large data of the song information, the song may be transmitted in a wired manner from the HMI system 40 through the in-vehicle connector 10 directly into the in-vehicle speaker 20, without passing through the vehicle network 30; it is understood that, when the car speaker 20 has an infinite transmission module, after the HMI system 40 receives the song data request message, it can directly perform data transmission with the car speaker 20 through a wireless transmission module, such as bluetooth.
Further, when there is no song corresponding to the current state of the driver in the storage device of the vehicle, the vehicle sound box 20 sends the assisting action request information to the vehicle connector 10, so that the wireless transmission device 60 requests the cloud server 70 to download the song of the type, when the wireless transmission device 60 downloads the song of the type from the cloud server 70, the song is stored in the HMI system 40, and then the HMI system 40 and the vehicle sound box 20 perform transmission of the song.
Further, when the in-vehicle speaker 20 acquires the drowsiness state of the driver from the in-vehicle connector 10 and receives the information that the in-vehicle coffee maker is connected to the in-vehicle connector 10, the in-vehicle speaker 20 transmits the assisting action request information to the in-vehicle connector 10 to start the coffee making operation by the in-vehicle coffee maker.
In the second embodiment of the present invention, the car speakers 20 provide different services according to the state of the vehicle.
For example, in the vehicle sleep state, when the in-vehicle connector 10 receives a signal from within the vehicle CAN network 30 that the driver has entered the vehicle wake-up range, the in-vehicle connector 10 wakes up the in-vehicle speaker 20, and when the in-vehicle connector 10 receives a signal that the door is opened again, the in-vehicle connector 10 transfers the information to the in-vehicle speaker 20. After receiving the information, the car speaker 20 may determine that the driver needs to use the vehicle at this time, and the car speaker 20 starts to broadcast welcome words, such as "welcome owner" or the like, so as to improve driving comfort.
When the vehicle is started, the car audio box 20 obtains information that the vehicle has been started from the car connector 10, and the car audio box 20 actively inquires about the travel of the vehicle.
When the vehicle is running, the vehicle-mounted sound box 20 obtains information that the speed of the vehicle is greater than the first speed threshold value but less than the second speed threshold value from the vehicle-mounted connector 10, and the vehicle-mounted sound box 20 plays music with rhythm intensity. When information that the vehicle speed of the vehicle is less than the first vehicle speed threshold is acquired, the in-vehicle sound box 20 plays a soft type of music. The related kind of music may be set in advance by setting in advance through the remote controller 70 or the HMI system 40.
When the preset type of music is not stored in the car audio amplifier 20, the way of acquiring the music may be the same as the previous embodiment.
With regard to other control manners of the car-mounted sound box 20, other embodiments may be referred to.
In the third embodiment of the present invention, the in-vehicle connector 10 acquires the state information of the in-vehicle occupant from the vehicle network 30 and transmits it to the in-vehicle sound box 20, and the in-vehicle sound box 20 controls the volume of the in-vehicle occupant according to the state of the in-vehicle occupant.
When the driver is not drowsy but the in-vehicle speaker 20 receives information transmitted by the in-vehicle connector 10 that an event occurs in which a passenger is sleeping or making a call to reduce the volume demand, the in-vehicle speaker lowers the volume of the in-vehicle speaker to the first volume threshold.
Further, when the vehicle-mounted sound box 20 reduces the volume of the vehicle to the first volume threshold value and receives information indicating that the sound of the vehicle-mounted passenger to the environment in the vehicle is not full, such as when the vehicle-mounted sound box indicates "cannot hear", "what you say", "say again" or the like, the vehicle-mounted sound box 20 continues to reduce the volume of the vehicle to the second volume threshold value, and sends assistance action request information to the vehicle-mounted connector 10 to request the vehicle to perform a window closing action, so as to prevent the external noise of the vehicle from affecting the vehicle.
In the present embodiment, because the vehicle-mounted sound box 20 can analyze the language of the detected occupant more accurately than the sound pickup unit of the vehicle interior itself due to its professional nature, a signal indicating that the sound of the vehicle interior occupant indicates dissatisfaction with the vehicle interior environment can be obtained by analyzing the language of the vehicle interior occupant by the sound pickup unit of the vehicle-mounted sound box 20 itself.
In this embodiment, with the help of the processing system of the vehicle itself and the information collecting device of the vehicle itself, the car-mounted speaker 20 itself may not perform complex analysis of the original data, as long as after the event in the monitoring event set occurs, corresponding actions are performed according to the type of the occurring preset event. This simplifies the control logic of the in-vehicle sound box 20 itself, and reduces the cost of the in-vehicle sound box 20.
With regard to other control manners of the car-mounted sound box 20, other embodiments may be referred to.
In the fourth embodiment of the present invention, the in-vehicle speaker 20 recognizes the voice command of the occupant in the vehicle, and transmits the command information of the occupant in the vehicle to the target device of the command through the in-vehicle connector 10, so that the target device performs corresponding actions according to the voice command of the occupant in the vehicle.
In the present embodiment, due to the professional nature of the car audio 20, it can analyze the detected language of the occupant more accurately than the sound pickup unit of the car, so as to recognize the voice command of the occupant more accurately.
After recognizing the voice command, when the target device of the voice command is the vehicle device, the vehicle-mounted sound box 20 sends the assisting action request information of the vehicle device through the vehicle-mounted connector 10, and the vehicle-mounted connector 10 transmits the assisting action request information to the vehicle network 30, so that the vehicle device acquires the command and performs corresponding action according to the voice command; when the target device of the voice command is other peripheral devices, the car sound box 20 sends the assistance action request information of the other peripheral devices to the other peripheral devices through the car connector 10, so that the other peripheral devices perform corresponding actions according to the voice command.
Further, when the target device of the voice command is other peripheral devices, the car sound box 20 may also send data request information whether the target peripheral device is connected to the car connector to obtain the connection condition of the target peripheral device, and when the target peripheral device is not connected to the car connector 10, feed back the information that the target peripheral device is not connected; when the target peripheral device is connected to the in-vehicle connector 10, assist action request information of other peripheral devices is transmitted to the in-vehicle connector 10.
That is, in this embodiment, the car-mounted sound box replaces the functions of the sound pickup unit of the car and the voice command analysis module, so that the passenger in the car can perform voice control on the car and other peripheral devices according to the car-mounted sound box 20, and the intelligence level of the car can be improved.
For example, when the car speaker 20 recognizes that a car occupant sends a command to turn on the air purifier, the car speaker 20 sends an operation assisting request message for turning on the air purifier to the car connector 10, so as to turn on the air purifier; when the vehicle-mounted sound box 20 recognizes that the vehicle-mounted passenger sends a command for starting the off-road mode, the vehicle starts the off-road mode to run in the off-road mode.
