This application discloses a vehicle control method, the flow chart of which is shown in Figure 1, including:

Step S11: Obtain the lighting control request;

Step S12: Call the vehicle control service of the vehicle based on the lighting control request;

Step S13: If it is determined based on the vehicle control service that the current operating status of the vehicle meets the lighting control conditions, the vehicle's music service is called, and the corresponding music interface is called based on the music service to output preset music based on the music interface;

Step S14: Based on the pre-stored correspondence between music and lighting modes, determine the lighting mode that matches the preset music output by the vehicle, call the exterior light (external car light) service, and call the lighting mode corresponding to the preset music through the exterior light service external light interface so that by calling the external The light interface controls the exterior light output light in the corresponding exterior light module.

When controlling the vehicle's lights, it at least includes controlling the lights while the vehicle is driving, such as: controlling the left turn signal to flash when turning left, and controlling the brake lights to light up when braking; in addition, The car lights can also be controlled in a lighting mode that matches the music. In this solution, the lighting mode that matches the music is controlled, and the interface of each exterior light in the exterior light module is called through the SOA architecture (service-oriented architecture). Achieve control of different lighting modes and achieve rapid iteration.

Obtaining the lighting control request can be: the user triggers a specific button, and the specific button outputs a lighting control request so that the vehicle control system (vehicle control unit) (such as the central computing unit (central computing unit) or the audio-visual entertainment system (in- Vehicle audio and video entertainment unit)) controls the lighting mode that matches the music based on this specific button; or it can also be: the user inputs specific instructions on the human-computer interaction interface so that the system obtains the lighting control request; or it can also be is: used to input voice. Based on the analysis of the voice, the system determines that the user requests control of the lighting mode that matches the music.

After obtaining the lighting control request, the vehicle control system directly calls the vehicle's vehicle control service to control the vehicle based on the lighting control request. After obtaining the lighting control request, it is first necessary to determine whether the current operating status of the vehicle meets the lighting control conditions. Therefore, it is first necessary to determine the current operating status of the vehicle based on the vehicle control service.

If it is determined that the current operating status of the vehicle does not meet the lighting control conditions, the subsequent lighting mode control will be terminated and a prompt message will be output to make the user clear that the current vehicle does not meet the lighting control conditions; if it is determined that the current operating status of the vehicle meets the lighting control conditions, Then call the exterior light service to call the corresponding exterior light interface as needed to achieve lighting control. Specifically, you can first call the vehicle's music service, and call the corresponding music interface under the music service through the music service to output preset music based on the music interface. , that is, calling the music interface to make the vehicle's audio-visual entertainment system output preset music.

While the vehicle outputs the preset music, the system will determine the lighting mode that matches the preset music. That is, the system will pre-store the corresponding relationships between different music and lighting modes. As long as the preset music output by the vehicle is the pre-stored correspondence. For any of the relationships, you can directly determine the lighting mode corresponding to the preset music through the corresponding relationship, call the exterior light service, and then directly call the exterior light interface under the exterior light service corresponding to the lighting mode to control the exterior light corresponding to the called exterior light interface. in module The external lights can output light.

Specifically, an exterior light interface corresponds to an exterior light in the exterior light module. For example, the first exterior light interface corresponds to the left front high beam, and the second exterior light interface corresponds to the right front high beam. In a certain lighting mode, the first exterior light needs to be called. interface and the second exterior light interface, directly call the first exterior light interface and the second exterior light interface. When the first exterior light interface is called, the left front high beam lights up, and when the second exterior light interface is called, the right front high beam lights up.

That is, different combinations of underlying basic service interfaces are made through application layer software to achieve the output of different lighting modes.

When a new lighting mode needs to be added, the corresponding relationship stored in the system can be directly adjusted. The lighting mode corresponding to the pre-stored music can be modified, or music not stored in the system can be added to match the newly added lighting mode. correspond.

Among them, the exterior light module of the vehicle includes the exterior lights of the vehicle.

Calling the exterior light service is a prerequisite for calling any exterior light. After calling the exterior light service, the called exterior light interface can control the lighting of the corresponding exterior light.

Based on the SOA architecture, the control of lighting and music output is realized by calling various basic services in the system, such as vehicle control service, exterior light service, music service, etc., and when the lighting mode needs to be changed, different calls are made through the exterior light service. The external light interface realizes the output of different lighting modes in different modes. By reassembling the service interface, the development cycle is shortened and the iteration speed of functions is improved.

It should be noted that the vehicle control method disclosed in this embodiment is executed by the vehicle control system, and it is implemented under the SOA architecture, that is, the vehicle control system obtains the lighting control request, and the vehicle control system calls based on the lighting control request. The vehicle control service of the vehicle. The vehicle control system determines that the current operating status of the vehicle meets the lighting control conditions based on the vehicle control service, calls the vehicle's music service, and calls the corresponding music interface based on the music service to output preset music based on the music interface. Based on the pre-stored correspondence between music and lighting modes, the vehicle control system determines the mode that matches the preset music output by the vehicle, calls the exterior light service, and adjusts the lighting mode through the exterior light service. Use the exterior light interface corresponding to the mode matching the preset music to control the exterior light output light in the corresponding exterior light module through the called exterior light interface;

It can also be: executed by the audio and video entertainment system of the vehicle, that is, the audio and video entertainment system obtains the lighting control request, the audio and video entertainment system calls the vehicle's vehicle control service based on the lighting control request, and the audio and video entertainment system determines the current operation of the vehicle based on the vehicle control service. When the state meets the lighting control conditions, the vehicle's music service is called, and the corresponding music interface is called based on the music service to output preset music based on the music interface. The audio-visual entertainment system determines the corresponding relationship between the music and the lighting mode based on the pre-stored music and lighting modes. Preset the lighting mode matching the music, call the exterior light service, and call the exterior light interface corresponding to the lighting mode matching the preset music through the exterior light service, so that the exterior light output light in the corresponding exterior light module can be controlled through the called exterior light interface.

When a new external light module output light mode needs to be added, the corresponding relationship only needs to be adjusted, realizing rapid iteration of functions and shortening the development cycle; and, the external light module is called through services and interfaces. As long as the external light interface is combined in different ways, different modes of light show output can be achieved, enabling rapid iteration of functions and shortening the development cycle.

This embodiment discloses a vehicle control method, the flow chart of which is shown in Figure 2, including:

Step S21: Obtain the lighting control request;

Step S22: Call the vehicle control service of the vehicle based on the lighting control request to obtain at least the current driving status, power status, hazard warning light status and turn signal status of the vehicle;

Step S23: If it is determined based on the vehicle control service that the current operating status of the vehicle meets the lighting control conditions, the vehicle's music service is called, and the corresponding music interface is called based on the music service, so as to control the vehicle to output preset music based on the music interface;

Step S24: Based on the pre-stored correspondence between music and lighting modes, determine the lighting mode matching the preset music output by the vehicle, call the exterior light service, and call the exterior light interface corresponding to the lighting mode matching the preset music through the exterior light service, so that The exterior light output light in the corresponding exterior light module is controlled through the called exterior light interface.

The current operating status of the vehicle at least includes: the current driving status, power status, hazard warning light status and turn signal status of the vehicle. The current operating status of the vehicle can also include other information, such as: braking status, fuel tank valve status, etc., this implementation This example takes the vehicle's current driving status, power status, hazard warning light status, and turn signal status as examples.

The current operating status of the vehicle meets the lighting control conditions: each of the current operating status of the vehicle Each state satisfies the lighting control conditions, that is: the current driving state of the vehicle is stopped, the power state is that the power supply is in normal power supply state, the hazard warning light state is off, and the turn signal is also off.

Only when each of the above states meets the lighting control conditions can the vehicle's safety be ensured when the lighting mode matches the music.

Among them, the current driving state of the vehicle is a stopped state, which can be: determining that the vehicle's gear is in the parking gear P, or the vehicle is in a parking brake state, or determining that the vehicle is currently in parking through an image acquisition device installed on the vehicle field, it is determined that the vehicle is currently in a stopped state, etc.

The power supply is in a normal power supply state, which can be: the status bit of the power supply is ON; the hazard warning light is off, which can be: the hazard warning light is OFF; the turn signal is off, which can be: the turn signal status is OFF.

As long as any state does not meet the lighting control conditions, the system will not call the music interface to control the vehicle to output preset music, or the vehicle can call the music interface to output preset music. However, after outputting the preset music, it will not The exterior light service and exterior light interface will be called, and the vehicle's exterior light module will be controlled to output a lighting mode that matches the preset music to ensure the safety of the vehicle.

When there is an operating state that does not meet the lighting control conditions, the system will output a prompt message to remind the user that the lighting mode cannot be started to match the music, and the prompt message will indicate that the state that does not meet the lighting control conditions is the vehicle's Driving status, power status, danger and other alarm status and/or turn signal status.

Among them, the current driving status, power status, hazard warning light status and turn signal status of the vehicle are provided by the vehicle control system to the audio and video entertainment system. Specifically, the vehicle power supply status can be provided by the first core of the vehicle control system. , driving status, exterior light status, exterior light control, window control and other basic service interfaces. The first core of the vehicle control system converts the service interface into signals through S2S and sends them to the second core of the vehicle control system. The second core performs the above-mentioned basic services such as vehicle power status, driving status, exterior light status, exterior light control, and window control.

Only when the current operating status of the vehicle meets the lighting control conditions, the corresponding services and interfaces will be called to output the lighting mode and music matching. This avoids the need to adjust the vehicle's driving status, power supply status, hazard warning light status and /or when the turn signal status does not meet the lighting control conditions, Dangerous driving of the vehicle may occur due to the light mode output.

This embodiment discloses a vehicle control method, the flow chart of which is shown in Figure 3, including:

Step S31: Obtain the lighting control request;

Step S32: Call the vehicle control service of the vehicle based on the lighting control request;

Step S33: If it is determined based on the vehicle control service that the current operating status of the vehicle meets the lighting control conditions, the vehicle's music service is called, and the corresponding music interface is called based on the music service to output preset music based on the music interface;

Step S34: Determine the music type of the preset music output by the vehicle;

Step S35: Determine the first lighting mode corresponding to the music type of the preset music based on the pre-stored correspondence between the music and the lighting mode, call the exterior light service, and use the exterior light service to call the exterior lights of the exterior lights in the exterior light module required for the first lighting mode. interface to control the exterior light output light in the corresponding exterior light module through the exterior light interface of the exterior light required to implement the first lighting mode.

Determining the music type of the preset music output by the vehicle can be: Determine the output language of the preset music, that is, determine whether the preset music belongs to Chinese songs, English songs, or Japanese songs, etc. For music with different output voices, use different lights. Mode output lights to enable users to achieve different experience effects of music in different languages on the vehicle's music and light show;

It can also be: determine the music style of the preset music, such as: determine that the preset music belongs to classical music, pop music, folk music, rock music, disco music, etc., and output lights in different lighting modes for different styles of music, so as to This enables users to achieve different experience effects of different styles of music on the vehicle's music and light show.

That is, the corresponding relationship between the pre-stored music and the lighting mode is actually the pre-stored corresponding relationship between different music types and different lighting modes. When it is determined that there is preset music output, the preset music is directly analyzed to determine the preset The music type of the music, so that the pre-stored correspondence can be searched based on the music type to determine the first lighting mode corresponding to the music type of the preset music, so that the exterior light module can be controlled to output light in the first lighting mode.

Among them, calling the exterior light service can be: when calling the music service and outputting preset music through the music interface under the music service, the system will request the exterior light control in the vehicle control system to open the service interface through the SOA architecture, such as: Remote Light service opening interface, low beam service opening interface, brake light service opening interface, etc.

If the exterior light control opening service interface is successfully executed, the vehicle control system will report that the service execution is successful. The information is fed back to the audio-visual entertainment system, and the service is synchronously converted into signals and sent to the exterior light module, so that the exterior light module can turn on the successful exterior light lighting through the CAN signal drive service interface to execute high beam, low beam, and brake lights. Wait for the light to turn on.

Alternatively, it can also be: store the corresponding relationship between music types and different lighting modes in the exterior light module. After the system calls the music service and calls the music interface through the music service to control the vehicle to output the preset music, it directly sends the preset music to The exterior light module analyzes the preset music to determine the music type of the preset music, finds the first lighting mode corresponding to the music type, and calls the exterior light service, so that the exterior light module turns on and calls the corresponding function under the exterior light service. External light interface to output light in the first light mode;

Or, the corresponding relationship between music types and different lighting modes is stored in the exterior light module. After calling the music service and calling the music interface through the music service to control the vehicle to output the preset music, the system analyzes the preset music and determines the preset music. The music type of the music, and then directly sends the music type of the preset music to the exterior light module. The exterior light module searches for the pre-stored correspondence to determine the first lighting mode corresponding to the music type of the preset music, thereby calling the exterior light service, and directly Turn on and call the corresponding exterior light interface under the exterior light service to output light in the first lighting mode.

It should be noted that when outputting lights in different music modes, different car window services can also be opened and called simultaneously for different music types or different music, and different car window interfaces under the car window service can be called for control. The opening or closing of different windows can enhance the display effect of the music and light show on the vehicle.

When outputting the lighting mode, different types of music are matched with the lighting output of different lighting modes to ensure the user's experience of the music and light show on the vehicle.

This embodiment discloses a vehicle control method, the flow chart of which is shown in Figure 4, including:

Step S41: Obtain the lighting control request;

Step S42: Call the vehicle control service of the vehicle based on the lighting control request;

Step S43: If it is determined based on the vehicle control service that the current operating status of the vehicle meets the lighting control conditions, the vehicle's music service is called, and the corresponding music interface is called based on the music service to output preset music based on the music interface;

Step S44: Determine the output frequency band of the preset music output by the vehicle;

Step S45: Determine the preset music based on the pre-stored correspondence between music and lighting modes. The second lighting mode corresponding to the output frequency band calls the exterior light service. Through the exterior light service, the exterior light interface of the exterior light in the exterior light module required to implement the second lighting mode is called, so that the exterior light interface of the exterior light in the exterior light module required to implement the second lighting mode is used. The interface controls the exterior light output light in the corresponding exterior light module.

Determine the output frequency band of the preset music output by the vehicle, and the preset music can be a complete song or audio, or a part of a complete song or audio.

If the preset music is a complete song or audio, then determining the output frequency band of the preset music actually determines the frequency band in which the complete song or audio is located, or at least a preset proportion of the complete song or audio The frequency band in which the syllable is located.

If all the syllables output in the preset music are in the high-frequency band, determine that the output frequency band of the preset music is the high-frequency band, then determine the lighting mode corresponding to the high-frequency band, then call the exterior light service, and call the corresponding exterior light interface under the exterior light service. , output the light in the light mode corresponding to the high-frequency band, so that the light output in the light mode corresponding to the high-frequency band can be output synchronously with the music in the high-frequency band; similarly, if all the syllables output in the preset music are in the mid-frequency band, then it is determined If the preset music output frequency band is the mid-frequency band, then determine the lighting mode corresponding to the mid-frequency band, then call the exterior light service, and call the corresponding exterior light interface under the exterior light service to output the light in the light mode corresponding to the mid-frequency band, thereby realizing the mid-frequency band The lights output by the corresponding lighting mode are output synchronously with the music in the mid-frequency band; if all the syllables output in the preset music are in the low-frequency band, then determine that the output frequency band of the preset music is the low-frequency band, then determine the lighting mode corresponding to the low-frequency band. , and then calls the exterior light service, and calls the corresponding exterior light interface under the exterior light service, to output the light in the light mode corresponding to the low frequency band, thereby realizing the synchronized output of the light output in the light mode corresponding to the low frequency band and the music in the low frequency band.

Of course, when confirming the output frequency band, you can also set different frequency band ranges, and use different frequency band ranges as boundaries to determine different lighting modes, without limiting it to three frequency bands: high, middle and low.

If the preset music is a complete song or part of the audio, when the audio-visual entertainment system calls the corresponding music interface under the music service to output the music, it will determine the current frequency band of the output music in real time. As long as If the frequency band of the output music is determined to change, it means entering the next part. At this time, the lighting mode of the exterior light module output light is determined based on the changed frequency band, and the corresponding exterior light interface under the exterior light service is called to achieve the exterior light module output. The lighting pattern matches the frequency band of the music output by the audio-visual entertainment system.

That is: if the output frequency band of the preset music changes while the vehicle is outputting the preset music, When the first output frequency band is adjusted to the second output frequency band, the third lighting mode corresponding to the second output frequency band is determined based on the pre-stored correspondence between the music and the lighting mode, the exterior light interface under the called exterior light service is adjusted, and the third lighting mode is called The exterior light interface of the exterior light corresponding to the light mode is used to control the exterior light module of the vehicle to output light in the third light mode.

For example, if the music currently output by the audio-visual entertainment system is in the first output frequency band, the corresponding external light module calls the corresponding external light interface to output light in the fourth lighting mode; if the music frequency band output by the audio-visual entertainment system changes, it will be adjusted by the first output frequency band. is the second output frequency band, the corresponding exterior light module no longer outputs light in the fourth lighting mode, but also calls the exterior light service, except that it calls the exterior light interface corresponding to the third lighting mode under the exterior light service, thereby using the third Light mode outputs light.

For example: if the music currently output by the audio-visual entertainment system is 20Hz, then the left front turn signal and right front turn signal of the corresponding exterior light module will flash. If the music output by the audio-visual entertainment system at the next moment is 50Hz, the corresponding left front high beam of the exterior light module will flash. and the right front high beam flashes.

When outputting the lighting mode, the music of different output frequency bands is matched with the lighting output of different lighting modes to ensure the user's experience of the music and light show on the vehicle.

Further, the vehicle control method disclosed in this embodiment may also include:

If the music service is stopped to be called, the vehicle stops outputting the preset music, and further stops calling the exterior light service to stop outputting lights matching the preset music.

When the vehicle stops outputting the preset music, the output of the preset music can be completed. At this time, the calling of the music service and music interface stops, and the exterior light service and exterior light interface are no longer called. The exterior light module no longer uses the lighting mode matching the preset music. Output the light, that is, the vehicle’s music and light show ends;

Stop calling the music service and music interface, that is, the vehicle stops outputting the preset music. It can also be: after receiving the user's specific operation on the vehicle, the preset music playback stops. At this time, the call to the exterior light service and exterior light interface will also be stopped. , that is, the exterior light module no longer outputs light in a light mode that matches the preset music. Among them, the user's specific operation on the vehicle can be: the user's operation on the audio-visual entertainment system to stop music playback, or it can be: the user starts the vehicle. At this time, the operating status of the vehicle no longer meets the lighting control conditions, so the stop call Exterior light service and exterior light interface to terminate the exterior light module to output lights in a light mode that matches the preset music; or the user performs an operation of turning on the turn signal. At this time, the vehicle's operating status no longer meets the light control conditions, so the stop Call the exterior light service and exterior light interface to terminate the exterior light module with lights matching the default music Mode output lights.

When the audio-visual entertainment system determines to stop calling the exterior light service and exterior light interface, so that the vehicle's exterior light module stops outputting lights in the lighting mode matching the preset music, it is determined that the vehicle's music and light show has ended.
