[0002] Currently, smart cars are often equipped with ambient lighting and AI voice assistants. After being activated, the voice assistant responds to the user with voice. In scenarios with multiple passengers in the car, when the voice assistant is activated by passengers in different seats, it often uses voice prompts such as "Please speak in the front passenger seat" or "Please speak in the driver seat" to indicate which passenger has activated it. This results in poor interactivity and a lack of intelligence. Summary of the Invention

Figure 5A schematic diagram of an embodiment of the vehicle ambient lighting control device provided by the present invention is shown. Detailed Implementation
[0018] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein.
[0019] Figure 1 A flowchart illustrating a first embodiment of the vehicle ambient lighting control method provided by the present invention is shown. This method is executed by a vehicle ambient lighting control device, such as a vehicle controller. Figure 1 As shown, the method includes the following steps: Step 10: Determine the task processing stage based on the occupant status of the occupants in the vehicle to be controlled.
[0020] The vehicle to be controlled refers to the vehicle for which ambient lighting needs to be controlled. The ambient lighting can be installed inside the vehicle, such as in the center console or side doors. Occupants refer to the people in the vehicle to be controlled, which may include the driver and passengers.
[0021] In one implementation, the task processing stage can be determined based on the occupant's state, which can be the state of the voice emitted by the occupant, such as the state of waking up a voice assistant or issuing a voice command. The task processing stage can include the task recognition state or the task execution state.
[0022] Step 20: Determine the ambient lighting effect corresponding to the vehicle to be controlled based on the task processing stage.
[0023] In one implementation, the ambient lighting effect inside the vehicle to be controlled can be determined according to the task processing stage, such as a low-frequency "heartbeat" lighting effect, a "breathing" lighting effect, or a "wave" lighting effect. The ambient lighting effect is also different for different task processing stages, and the occupants can also determine which task processing stage they are currently in based on the ambient lighting effect.
[0024] Step 30: Control the ambient lighting inside the vehicle to be controlled based on the ambient lighting effect.
[0025] In one implementation, the ambient lighting inside the vehicle to be controlled can be controlled based on the ambient lighting effect, that is, the ambient lighting can be controlled to operate according to the ambient lighting effect.
[0026] As can be seen from the above, in the vehicle ambient lighting control method provided by the embodiments of the present invention, a task processing stage is determined according to the occupant status of the occupants in the vehicle to be controlled, then the ambient lighting effect corresponding to the vehicle to be controlled is determined according to the task processing stage, and then the ambient lighting inside the vehicle to be controlled is controlled based on the ambient lighting effect. The embodiments of the present invention determine the task processing stage based on the occupant status, and then determine the ambient lighting effect based on the task processing stage, which can expand traditional voice interaction into a multi-dimensional interaction of sound and vision, thereby controlling the ambient lighting inside the vehicle based on the ambient lighting effect, improving the user experience, and creating a more technologically advanced in-vehicle atmosphere.
[0027] Figure 2 A flowchart illustrating a second embodiment of the vehicle ambient lighting control method provided by the present invention is shown. This method is executed by a vehicle ambient lighting control device. Figure 2 As shown, step 10 includes the following steps: Step 101: Determine the occupant status of the occupants in the vehicle to be controlled.
[0028] In one implementation, the occupant status of the occupant in the vehicle to be controlled can be determined, such as the status of waking up a voice assistant or issuing a voice command.
[0029] Step 102: If the occupant's status is "voice assistant activated", determine the task processing stage as the task initiation stage.
[0030] If the voice assistant on the vehicle to be controlled is already activated, then when the occupant is in the state of waking up the voice assistant, the task processing stage is determined to be the task initiation stage. The task initiation stage can be a state of preparing to execute the task issued by the occupant.
[0031] Step 103: When the occupant status is "start collecting initial voice commands", determine that the task processing stage is the task recognition stage.
[0032] In one implementation, if the occupant issues an initial voice command, the occupant's state can be considered as starting to collect the initial voice command. The initial voice command can be something like turning on the air conditioner or adjusting the windows. The task processing stage is then defined as the task recognition stage, during which the initial voice command issued by the occupant can be recognized.
[0033] Step 104: If the occupant status is "End initial voice command acquisition", then determine the task processing stage as the task execution stage.
[0034] In one implementation, if the passenger has finished speaking the initial voice command, the passenger status can be set to "End of initial voice command acquisition", and the task processing stage can be set to the task execution stage. The task execution stage can execute the recognized initial voice command.
[0035] As can be seen from the above, in the vehicle ambient lighting control method provided by the embodiments of the present invention, by determining the occupant state corresponding to the occupant in the vehicle to be controlled, the task processing stage is determined to be the task initiation stage when the occupant state is waking up the voice assistant; the task processing stage is determined to be the task recognition stage when the occupant state is starting to collect initial voice commands; and the task processing stage is determined to be the task execution stage when the occupant state is ending the collection of initial voice commands. The embodiments of the present invention can determine the task processing stage according to the occupant state, and control the ambient lighting to produce different lighting effects for different task processing stages, thereby allowing the occupant to determine the task processing progress based on the ambient lighting effects.
[0036] Figure 3 A flowchart illustrating a third embodiment of the vehicle ambient lighting control method provided by the present invention is shown, the method being executed by a vehicle ambient lighting control device. Figure 3 As shown, step 20 includes the following steps: Step 201: If the task processing phase is the task initiation phase, determine the target passenger who will wake up the voice assistant.
[0037] In one implementation, when the voice assistant on the vehicle to be controlled is activated and is waiting to be woken up in the background, the ambient lighting effect can be a low-frequency "heartbeat" effect at the central ambient light position of the vehicle's control center console. This effect can convey the meaning that the voice assistant can be woken up and that the voice assistant has been activated.
[0038] In one implementation, when the task processing phase is the task initiation phase, the target occupant for waking up the voice assistant can be determined. The target occupant can be either the driver or a passenger.
[0039] Step 202: Determine the occupant's position within the vehicle to be controlled.
[0040] Among them, the position of the target occupant in the vehicle to be controlled can be determined, and the occupant position can be the rear seat, the driver's seat, the front passenger seat, etc.
[0041] In one alternative approach, step 202 includes: acquiring the initial voice command issued by the target occupant through each microphone in the microphone array within the vehicle to be controlled; determining the signal acquisition time and signal strength corresponding to each initial voice command; and determining the occupant position of the target occupant within the vehicle to be controlled based on the time difference between each signal acquisition time and the intensity difference between each signal strength.
[0042] In one implementation, the initial voice command issued by the target occupant can be acquired by a microphone array inside the vehicle to be controlled. The microphone array can consist of multiple microphones. Therefore, after the target occupant issues the initial voice command, each microphone can acquire the initial voice command, but the acquisition time and the received signal strength may be different.
[0043] In one implementation, for each microphone, the signal acquisition time and signal strength of the initial voice command arriving at each microphone can be determined, and the time difference and intensity difference between different microphones can be determined. Then, the position and direction of the sound source can be determined based on the time difference and intensity difference, thereby enabling the determination of the position of the target occupant in the vehicle to be controlled.
[0044] Step 203: Determine the lighting effect area to be turned on based on the central control position and the occupant position of the vehicle to be controlled, and determine the ambient lighting effect corresponding to the vehicle to be controlled based on the lighting effect area to be turned on.
[0045] In one implementation, when the task processing phase is the task initiation phase, indicating that it is in a listening state, the area between the central control position and the passenger position of the vehicle to be controlled can be used as the lighting effect area, and the ambient lighting effect corresponding to the vehicle to be controlled can be determined according to the lighting effect area.
[0046] In one implementation, after the target occupant activates the AI voice assistant at their location, a "flowing" lighting effect is used. The light originates from the center console, flows to the vicinity of the target occupant, and then uses a "breathing" lighting effect at the occupant's location, creating a "wrapping" and "floating" tactile effect, awaiting further instructions from the occupant. During this time, ambient lights in other locations remain off. In other words, for target occupants in different locations, the ambient lighting starts at the central area of the center console and ends at the occupant's location.
[0047] In one alternative approach, step 20 includes: when the task processing stage is the task identification stage, using the ambient lighting around the occupant's position as the identification lighting effect area; and determining the ambient lighting effect corresponding to the vehicle to be controlled based on the identification lighting effect area.
[0048] In one implementation, when the task processing phase is the task identification phase, the ambient lighting around the target occupant's location can be used as the effective identification area. For example, if the occupant's location is the front passenger seat, the ambient lighting may include the floor and side door ambient lighting, and these ambient lights can be used as the effective identification area. The ambient lighting effect can be a "wave" effect, that is, using a "wave" effect in the ambient lighting around the target occupant to convey the meaning of "instruction identification in progress".
[0049] In one implementation, when the task processing phase is the task execution phase, the ambient lighting effect can start from the vicinity of the target occupant, use a "flowing" lighting effect, return to the central control area, use a fast-paced, rapidly cycling lighting effect during the command response to indicate that the command is running, and after the operation is completed, restore the voice assistant to the wake-up state, and the ambient lighting effect returns to a low-frequency "heartbeat" lighting effect.
[0050] In one alternative approach, step 20 includes: if the task processing stage is an abnormal task processing stage, determining the corresponding abnormality type; and determining the ambient lighting effect corresponding to the vehicle to be controlled based on the abnormality type.
[0051] In one implementation, if the task processing stage is a task processing exception stage, it is explained that the target passenger has issued a task processing exception. At this time, the corresponding exception type can be determined, and different exception types can correspond to different ambient lighting effects.
[0052] In one implementation, if the anomaly is a failure to recognize a voice command, the ambient light effect can be a brief, rapid "double flash" effect, controlling the flashing frequency and fluctuation range of brightness to indicate unsuccessful recognition, before returning to the listening or wake-up state, i.e., returning to the state where the voice assistant is enabled or activated. If the anomaly is a hardware failure or functional malfunction, the ambient light effect can be a non-glaring orange, red, or other high-priority light color, using a "triple flash" effect to indicate the fault.
[0053] In one alternative approach, after step 30, the method further includes: denoising the initial voice command issued by the target occupant to obtain a target voice signal; performing voice recognition on the target voice command; and controlling the vehicle to be controlled based on the voice recognition result.
[0054] In one implementation, after the target occupant issues the initial voice command, the initial voice command can be denoised to eliminate noise and the influence of different speakers. Specifically, echo cancellation, adaptive filtering, noise suppression and other methods can be used to remove noise from the initial voice signal to obtain the target voice signal.
[0055] In one implementation, the target voice command can be recognized by voice to obtain the voice recognition result, and the vehicle controller can then control the vehicle to be controlled based on the voice recognition result.
[0056] As can be seen from the above, in the vehicle ambient lighting control method provided by the embodiments of the present invention, when the task processing stage is the task initiation stage, the target occupant who wakes up the voice assistant is determined, then the occupant's position in the vehicle to be controlled is determined, then the lighting effect area is determined according to the central control position of the vehicle to be controlled and the occupant's position, and finally the ambient lighting effect corresponding to the vehicle to be controlled is determined according to the lighting effect area. In the case of the task processing stage being the task initiation stage, the embodiments of the present invention determine the lighting effect area according to the central control position of the vehicle to be controlled and the target occupant's position, and determine the ambient lighting effect according to the lighting effect area, thereby controlling the interior ambient lighting of the vehicle based on the ambient lighting effect, improving the user experience.

[0059] In one alternative embodiment, the stage determination module 410 is further configured to determine the occupant status corresponding to the occupant in the vehicle to be controlled; if the occupant status is to wake up the voice assistant, the task processing stage is determined to be the task initiation stage; if the occupant status is to start collecting initial voice commands, the task processing stage is determined to be the task recognition stage; and if the occupant status is to end collecting initial voice commands, the task processing stage is determined to be the task execution stage.
