The vehicle includes a plurality of audio devices, wherein a first audio device is configured as a master node of the vehicular audio network and a second audio device is configured as a slave node of the vehicular audio network. The method comprises the following steps:
and S11, determining that the vehicle has a first preset event.
The first preset event may be the reception of a trigger instruction. For example, when there is a need for maintenance or a new audio device needs to be added, the user issues a corresponding trigger instruction. The remote triggering instruction can also be received, for example, the instruction sent by the head car to reset the car audio network is received through the internet of vehicles when the fleet goes out.
In addition, the first preset event may also be a preset fault occurring in the vehicle. For example, the first preset event may be that the in-vehicle telematics terminal receives a preset fault signal through a CAN bus. It is worth mentioning that, when a serious collision accident occurs to the vehicle, the vehicle-mounted telematics terminal may receive a generated preset fault signal, for example, a collision signal or an airbag ignition signal, through the CAN bus.
For another example, the first preset event may be detection of failure of any one of the infotainment host, the battery, or the speaker in the vehicle. In which the infotainment host fails, meaning that the master node of the audio network fails. A battery failure indicates that the vehicle may have a serious malfunction. And the speaker is one of the audio devices of the vehicle, and failure of the speaker indicates that a link of the audio network of the vehicle may fail.
And S12, reconfiguring the node authority of the audio equipment to obtain a new vehicle-mounted audio network with the second audio equipment as a main node.
Specifically, the node authority of the audio device may be reconfigured by reconfiguring a control chip of each audio device on the vehicle-mounted audio bus, or by changing a protocol of the audio bus. Based on the inventive concept, the exchange of the master node and the slave node between any audio devices on the audio bus can be realized.
The technical scheme can at least achieve the following technical effects:
when the preset event of the vehicle is determined, the node authority of the audio equipment of the vehicle is reconfigured, so that a new vehicle-mounted audio network with another audio equipment as a main node is obtained, the flexibility of vehicle-mounted audio network configuration can be increased, and the requirements of different use scenes are met.
In an optional implementation manner, the second audio device is a vehicle-mounted telematics terminal, the second audio device is connected to a third audio device, and the third audio device is a microphone; the reconfiguring the node permission of the audio device to obtain a new in-vehicle audio network with the second audio device as a master node, comprising: restarting the transceiver of the vehicle-mounted remote information processing terminal, and enabling the restarted transceiver of the vehicle-mounted remote information processing terminal to be in a working mode of working under the authority of a master node, so as to form a new vehicle-mounted audio network with the vehicle-mounted remote information processing terminal as the master node and the microphone as a slave node.
With the increasing popularity of car networking related technologies, the car telematics terminal (T-BOX) gradually changes to the standard configuration of the vehicle, and its own configuration with a higher security level, including a backup battery and a separate backup speaker for emergency call completion, and its own audio or voice input/output channel, all determine the requirement that the car telematics terminal can be relatively independent and maintain higher reliability of use.
If the second audio device is a vehicle-mounted telematics terminal (T-BOX), an emergency vehicle-mounted audio network using the vehicle-mounted telematics terminal as a master node can be formed when a preset fault event occurs, so that the transceiving operation of audio information is performed based on the new vehicle-mounted audio network, and a guarantee can be provided for an emergency function of the vehicle.
Additionally, the vehicle may further include a fourth audio device, such as an external digital power amplifier. When the vehicle audio network is reconfigured, the node permissions of the audio devices can be adjusted as needed.
Optionally, if the first audio device is an infotainment host, the first preset event is that the vehicle-mounted remote information processing terminal receives a preset fault signal through a CAN bus; prior to reconfiguring the node permissions of the audio device, the method further comprises: sending a control signal to the infotainment host instructing to power off a transceiver of the infotainment host.
Specifically, the main control chip of the in-vehicle telematics terminal notifies the main node (infotainment host) to turn off the power supply of the main node transceiver through a remote GPIO (general purpose Input/Output) of the audio bus.
And after the vehicle-mounted remote information processing terminal determines that the power supply of the information entertainment host transceiver is cut off, the vehicle-mounted remote information processing terminal restarts the transceiver of the vehicle-mounted remote information processing terminal and autonomously acquires the authority of the main node. And the vehicle-mounted remote information processing terminal and the microphone are respectively configured into a main node and a first slave node, and a new vehicle-mounted audio network is established.
Optionally, if the first audio device is an infotainment host, the vehicle further comprises a battery and a speaker in the vehicle; the first preset event is that any one of the storage battery and the loudspeaker in the vehicle fails when the information entertainment host is detected; prior to reconfiguring the node permissions of the audio device, the method further comprises: and lowering the level of a state notification signal sent by the infotainment host to the vehicle-mounted telematics terminal.
Specifically, a communication line for sending remote GPIO signals for informing the state of the infotainment host is arranged at the infotainment host side. If any device in the battery or the loudspeaker in the vehicle fails, a remote GPIO signal for informing the state of the infotainment host computer can be set low.
It is worth mentioning that if the speaker fails and the battery and the infotainment host do not fail, the battery can still supply power to the infotainment host. The in-vehicle telematics terminal may be configured to autonomously restart if it detects that the remote GPIO signal is low. In the event of a speaker failure, the in-vehicle telematics terminal may be autonomously restarted by detecting that the remote GPIO signal is low by lowering the remote GPIO signal used to notify the infotainment host of the status.
It is worth mentioning that if the battery fails, the battery stops supplying power to the infotainment host, and the remote GPIO signal is lost; alternatively, the infotainment host signal fails and the loss of the remote GPIO signal may be considered to be a signal that is substantially low due to the loss of signal.
Thus, the vehicle-mounted remote information processing terminal can automatically restart according to the fact that the signal is set to be low or the fact that the signal is set to be low due to signal loss, acquire the authority of the main node and establish a new vehicle-mounted audio network.
The new audio network may include only the car telematics terminal as a master node and the microphone as a first slave node, so that the new car audio network may be minimally interfered by other audio devices and perform transceiving operations of alarm information and distress information in a minimized emergency-specific audio network mode, thereby providing a guarantee for emergency functions of the vehicle.
Fig. 2 is a flowchart illustrating a configuration method of an in-vehicle audio network according to an exemplary embodiment of the present disclosure. The vehicle includes a plurality of audio devices, wherein a first audio device is configured as a master node of the vehicular audio network and a second audio device is configured as a slave node of the vehicular audio network. The method comprises the following steps:
and S21, determining that the vehicle has a first preset event.

For example, when there is a need for maintenance or a new audio device needs to be added, the user issues a corresponding trigger instruction. The remote triggering instruction can also be received, for example, the instruction sent by the head car to reset the car audio network is received through the internet of vehicles when the fleet goes out.
In addition, the first preset event may also be a preset fault occurring in the vehicle. For example, the first preset event may be that the in-vehicle telematics terminal receives a preset fault signal through a CAN bus. It is worth mentioning that, when a serious collision accident occurs to the vehicle, the vehicle-mounted telematics terminal may receive a generated preset fault signal, for example, a collision signal or an airbag ignition signal, through the CAN bus.
For another example, the first preset event may be detection of failure of any one of the infotainment host, the battery, or the speaker in the vehicle. In which the infotainment host fails, meaning that the master node of the audio network fails. A battery failure indicates that a serious malfunction of the vehicle may occur and, in one possible case, the infotainment host may also be disabled accordingly. And the speaker is one of the audio devices of the vehicle, and failure of the speaker indicates that a link of the audio network of the vehicle may fail.
And S22, reconfiguring the node authority of the audio equipment to obtain a new vehicle-mounted audio network with the second audio equipment as a main node.
Specifically, the node authority of the audio device may be reconfigured by reconfiguring a control chip of each audio device on the vehicle-mounted audio bus, or by changing a protocol of the audio bus. Based on the inventive concept, the exchange of the master node and the slave node between any audio devices on the audio bus can be realized.
Further, the transceiving operation of the audio information may be performed based on the above-described new in-vehicle audio network.
When the preset event of the vehicle is determined, the node authority of the audio equipment of the vehicle is reconfigured, so that a new vehicle-mounted audio network with another audio equipment as a main node is obtained, the flexibility of vehicle-mounted audio network configuration can be increased, and the requirements of different use scenes are met.
And S23, determining that the vehicle has a second preset event.
The second preset event may be that the transceiving operation of the audio information is completed based on the new in-vehicle audio network. Or receiving a related trigger instruction, for example, after completing the maintenance or adding a new audio device, the user sends a corresponding trigger instruction.
S24, if the first audio equipment is detected to be in the normal working mode, reconfiguring the node authority of the plurality of audio equipment, and recovering the vehicle-mounted audio network with the first audio equipment as the main node.
For example, after completing audio transceiving operations such as emergency call, accident information transmission and the like, the in-vehicle telematics terminal may detect a remote GPIO signal for notifying the infotainment host of the status again. Or after completing the audio transceiving operations such as emergency call, accident information transmission and the like and restarting the vehicle, the vehicle-mounted remote information processing terminal can detect the remote GPIO signal for informing the state of the infotainment host again. In addition, the triggering condition before the vehicle-mounted telematics terminal detects the remote GPIO signal for notifying the infotainment host of the status again may be set according to actual use requirements, and the disclosure is not limited herein.
If the infotainment host is determined not to be in the normal working mode according to the signal, the current vehicle-mounted audio network is maintained, and the infotainment host receives the audio information transceiving instruction from the power management strategy response of the infotainment host. If the infotainment host is determined to be in the normal working mode according to the signal, the infotainment host and the transceivers of the vehicle-mounted terminal are restarted again, the infotainment host acquires the authority of the main node again, and the vehicle-mounted audio network with the first audio equipment as the main node is recovered, namely, the infotainment host is configured as the vehicle-mounted audio network in the conventional mode.
