[0114] The following describes the technical solutions of this application with reference to the accompanying drawings.

[0115] 1 is a functional block diagram of vehicle 100 according to an embodiment of the present application. In an embodiment, vehicle 100 is configured to be in a fully or partially autonomous driving mode. For example, vehicle 100 in the autonomous driving mode may control vehicle 100. Manual operations may be performed to determine the current state of the vehicle and the vehicle's surrounding environment, determine a possible behavior of at least one other vehicle in the surrounding environment, determine a confidence level corresponding to the probability that the other vehicle will perform the possible behavior, and control vehicle 100 based on the determined information. When vehicle 100 is in the autonomous driving mode, vehicle 100 may be configured to operate without human interaction.

[0116] Vehicle 100 may include various subsystems, such as a navigation system 102, a sensor system 104, a control system 106, one or more interface devices 108, a power source 110, a computer system 112, and a user interface 116. In embodiments, vehicle 100 may include more or fewer subsystems, and each subsystem may include multiple elements. Additionally, each subsystem and element of vehicle 100 may be interconnected in a wired or wireless manner.

[0117] The propulsion system 102 may include components that provide power for the vehicle 100 to move. In an embodiment, the propulsion system 102 may include an engine 118, an energy source 119, a transmission 120, and wheels / tires 121. The engine 118 may be an internal combustion engine, an electric motor, an air-compression engine, or a combination of other types of engines, such as a hybrid engine including a gasoline engine and an electric motor, or a hybrid engine including an internal combustion engine and an air-compression engine. The engine 118 converts the energy source 119 into mechanical energy.

[0118] Sensor system 104 may include several sensors that sense information about the environment surrounding vehicle 100. For example, sensor system 104 may include a positioning system 122 (which may be a GPS system, a Beidou system, or another positioning system), an inertial measurement unit (IMU) 124, a radar 126, a laser rangefinder 128, and a camera 130. Sensor system 104 may further include sensors of internal systems of vehicle 100 being monitored (e.g., an in-vehicle air quality monitor, a fuel gauge, or an engine oil temperature gauge). Sensor data from one or more of these sensors may be used to detect objects and corresponding characteristics of the objects (position, shape, orientation, speed, and the like). Such detection and identification are important functions of the safe operation of autonomous vehicle 100.

[0119] The control system 106 controls the operation of the vehicle 100 and the components of the vehicle 100. The control system 106 may include various elements, including a steering system 132, a throttle 134, a braking unit 136, a sensor fusion algorithm 138, a computer vision system 140, a path control system 142, and an obstacle avoidance system 144.

[0120] Vehicle 100 interacts with external sensors, other vehicles, other computer systems, or a user by using interface devices 108. Interface devices 108 may include a wireless communication system 146, an onboard computer 148, a microphone 150, and / or a speaker 152.

[0121] In some embodiments, interface device 108 provides a means for a user of vehicle 100 to interact with user interface 116. For example, onboard computer 148 may provide information for the user of vehicle 100. User interface 116 may further operate onboard computer 148 to receive user input. Onboard computer 148 may be operated by using a touchscreen. In other cases, interface device 108 may provide a means for vehicle 100 to communicate with another device located within the vehicle. For example, microphone 150 may receive audio (e.g., spoken commands or another audio input) from the user of vehicle 100. Similarly, speaker 152 may output audio to the user of vehicle 100.

[0122] The wireless communication system 146 may communicate with one or more devices directly or through a communication network. For example, the wireless communication system 146 may provide wireless communication by using an on-board antenna, such as 3G cellular communication, global system for mobile communications (GSM) communication technology, wideband code division multiple access (WCDMA) communication technology, 4G cellular communication (e.g., long term evolution (LTE) communication technology), or 5G cellular communication. The wireless communication system 146 may communicate with a wireless local area network (WLAN) by using an on-board antenna through Wi-Fi. In some embodiments, the wireless communication system 146 may communicate directly with devices through an infrared link or by using Bluetooth or ZigBee. Various vehicle communication systems, such as other wireless protocols, e.g., wireless communication system 146, may include one or more dedicated short range communications (DSRC) devices, which may include public and / or private data communications between vehicles and / or roadside stations.

[0123] Some or all functions of vehicle 100 are controlled by computer system 112. Computer system 112 may include at least one processor 113. Processor 113 executes instructions 115 stored on a non-transitory computer-readable medium, such as data storage device 114. Computer system 112 may alternatively be multiple computing devices that control individual components or subsystems of vehicle 100 in a distributed manner.

[0124] User interface 116 is configured to provide information for or receive information from a user of vehicle 100. In an embodiment, user interface 116 may include one or more input / output devices in the set of interface devices 108, such as a wireless communication system 146, an onboard computer 148, a microphone 150, and a speaker 152.

[0125] In an embodiment, one or more of the aforementioned components may be located separately from or associated with vehicle 100. For example, data storage device 114 may be partially or entirely separate from vehicle 1100. The aforementioned components may be communicatively coupled together in wired and / or wireless fashion.

[0126] In the embodiment, the above components are merely examples. In actual applications, components in the above modules may be added or deleted according to actual requirements. Figure 1 should not be understood as a limitation on the embodiments of this application.

[0127] Vehicle 100 may be an automobile, truck, motorcycle, bus, watercraft, aircraft, helicopter, lawn mower, recreational vehicle, playground vehicle, construction equipment, trolley, golf cart, train, wheelbarrow, or the like, which is not specifically limited in the embodiments of this application.

[0128] Ambient lighting, also known as ambient lighting, typically appears on vehicle steering wheels, center consoles, puddle lights, cup holders, ceilings, courtesy lights, courtesy pedals, vehicle doors, rear trunks, and vehicle lighting. Ambient lighting is typically expressed in single colors, multiple colors, breathing rhythms, musical rhythms, and similar. Satisfied ambient lighting gives people a sense of homely warmth and comfort, as well as technological beauty and luxury. In recent years, ambient lighting has gradually spread from high-end to mid-range vehicle models as a product for vehicle decoration and atmosphere creation. Exterior decorative lighting has also become popular in recent years, and exterior decorative lighting typically includes turn signals, brake lights, fog lights, flaps, side marker lights, vehicle headlights, plate lighting devices, chassis lights, wheel lights, and similar. Currently, ambient lighting, as a product for vehicle decoration and atmosphere creation, can only function to create a vehicle atmosphere, which leads to a poor user experience.

[0129] Embodiments of this application provide an interior lighting control method, an interior vehicle lighting system, and a vehicle. The interior vehicle lighting system can control interior lighting by using the real-time perception and computational capabilities of on-board artificial intelligence (AI). This helps improve the intelligence of the interior vehicle lighting system and thereby improve the user experience. For example, the interior vehicle lighting system can use interior lighting to indicate multiple functions or scenarios, such as voice assistant, vehicle status, autonomous driving, and vehicle infotainment system, so that the user can more easily understand the functions and the user's attention can be raised. For example, the interior vehicle lighting system can indicate autonomous driving in advance in an autonomous driving scenario. This helps to increase mutual trust between humans and machines and improve the driving experience. For example, the interior vehicle lighting system can further adaptively adjust lighting based on the scenario and communicate with the user by using personalized lighting signals.

[0130] Before the technical solutions in the embodiments of this application are described, a schematic diagram of the distribution of interior lighting according to the embodiments of this application will first be described with reference to Fig. 2. As shown in Fig. 2, position 1 indicates a reading spotlight, position 2 indicates an instrument panel environment strip light, position 3 indicates indirect light of instrument panel environment lighting, position 4 indicates a cup holder environment lighting, position 5 indicates a door panel environment strip light, position 6 indicates indirect light of door panel environment lighting, position 7 indicates a seat back environment strip light, position 8 indicates indirect light of auxiliary instrument panel environment lighting, and position 9 indicates indirect light of footwell environment lighting.

[0131] Two interior vehicle lighting systems provided in embodiments of this application are described below with reference to FIGS. 3 and 4. FIG. 3 is a schematic diagram of the structure of an interior vehicle lighting system according to an embodiment of this application. The interior vehicle lighting system may be a controller area network (CAN)-controlled system. The CAN-controlled system may include multiple sensors (e.g., sensor 301 and sensor 302), multiple electronic control units (ECUs), an in-vehicle infotainment host, an interior lighting controller, and interior lighting. The sensors include, but are not limited to, cameras, microphones, ultrasonic radar, millimeter-wave radar, lidar, vehicle speed sensors, motor power sensors, engine rotation speed sensors, and the like. The ECU is configured to receive data collected by the sensors, execute corresponding commands, and obtain periodic or event signals after executing the corresponding commands, so that the ECU can transmit signals to a public CAN network. The ECU includes, but is not limited to, a vehicle controller, a hybrid power controller, an automatic speed box controller, an autonomous driving controller, and the like. The in-vehicle infotainment host is configured to capture periodic signals or event signals transmitted by each ECU over the public CAN network, and when a corresponding signal state is identified, execute a corresponding lighting signal algorithm or forward the signal to the interior lighting controller. The interior lighting controller (e.g., ambient lighting controller) is configured to receive command signals from the in-vehicle infotainment host over the private CAN network and execute the lighting signal in a corresponding mode to execute power supply in striping, partitioning, dividing, and driving control for the interior lighting (e.g., ambient lighting). The interior lighting (e.g., ambient lighting) can be turned on, off, or flashing. For example, in an embodiment of this application, the in-vehicle infotainment host may capture a vehicle speed signal from the CAN bus.The in-vehicle infotainment host can calculate the acceleration of the vehicle based on the vehicle speed signal and send the acceleration to the interior lighting controller. The interior lighting controller determines a process of changing the color of the ambient lighting based on a mapping relationship between the acceleration and the color of the ambient lighting, so as to control the change of the ambient lighting. Alternatively, after calculating the acceleration of the vehicle, the in-vehicle infotainment host may determine the color of the ambient lighting based on the mapping relationship between the acceleration and the color of the ambient lighting and send the color of the ambient lighting to the interior lighting controller, so that the interior lighting controller determines the ambient lighting based on the color of the ambient lighting.

[0132] FIG. 4 is a schematic diagram of another structure of an interior vehicle lighting system according to an embodiment of this application. The interior vehicle lighting system may have a ring network communication architecture. All sensors and execution units (e.g., components such as interior lighting, air conditioning, and motors that acquire and execute commands) may be connected to a nearby vehicle integration unit (VIU). As a communication interface unit, the VIU may be deployed in a location where vehicle sensors and execution units are densely packed, allowing the vehicle sensors and execution units to perform nearby connections. In addition, the VIU may have certain calculation and driving capabilities (e.g., the VIU may absorb the driving calculation functions of some execution units). Sensors include, but are not limited to, cameras, microphones, ultrasonic radar, millimeter-wave radar, lidar, vehicle speed sensors, motor power sensors, engine rotation speed sensors, and the like.

[0133] It should be understood that the VIU may absorb the driving calculation functions of some sensors and executive units. In this way, when some executive units (e.g., CDC or VDC) fail, the VIU may directly process the data collected by the sensors to drive the interior lights to turn on, off, or blink.

[0134] The VIUs communicate with each other through networking. The intelligent driving computing platform / mobile data center (MDC), vehicle domain controller (VDC), and intelligent cockpit domain controller (CDC) are separately and redundantly connected to a ring network communication network formed by the VIUs. After the sensors collect data, they can send the collected data to the VIUs. The VIUs can publish the data on the ring network. The MDC, VDC, and CDC collect relevant data on the ring network, calculate the data, convert the data into corresponding lighting signals for the interior lights, and publish the signals on the ring network. Based on the corresponding calculation and driving capabilities of the VIUs, the interior lights are driven to execute the corresponding lighting signals or turn on or off.

[0135] As shown in FIG. 4 , it should be understood that there may be a correspondence between different VIUs and interior lights at different locations. For example, VIU1 is configured to drive interior light 1, VIU2 is configured to drive interior light 2, VIU3 is configured to drive interior light 3, and VIU4 is configured to drive interior light 4. The placement format of the VIUs may be unrelated to the interior lights. For example, VIU1 may be located at the left rear of the vehicle, and interior light 1 may be the driver's side door panel ambient light. Sensors or execution units can be connected to nearby VIUs, thereby reducing cable clutter. Due to the limited number of interfaces of the MDC, VDC, and CDC, a VIU can be connected to multiple sensors and multiple execution units to realize interface and communication functions.

[0136] It should be further understood that in embodiments of this application, the VIU to which a sensor or controller is connected, and the controller by which the connection is controlled, may be configured prior to delivery of the interior vehicle lighting system or may be defined by the user, and the hardware of the interior vehicle lighting system may be replaced and upgraded.

[0137] It should further be appreciated that the interior vehicle lighting systems in Figures 3 and 4 may be controlled to operate exterior decorative lighting in addition to interior lighting.

[0138] The above describes the schematic diagram of interior lighting and the structure of a vehicle interior lighting system with reference to Figures 2 to 4. The following describes the methods for controlling interior lighting in different scenarios provided in the embodiments of this application with reference to the accompanying drawings.

[0139] FIG. 5 is a schematic diagram of the effect of ambient lighting in a distributed speech scenario, according to an embodiment of this application.

[0140] 5(a), when the interior lighting system determines that a user in the driver's area is conversing with the in-vehicle voice assistant, the interior lighting system may activate ambient lighting in the driver's area. For example, the interior lighting system may control the instrument panel ambient strip light, the indirect light of the instrument panel ambient lighting, the door panel ambient strip light, the indirect light of the door panel ambient lighting, and the indirect light of the auxiliary instrument panel ambient lighting to be turned on in the driver's area.

[0141] 5(b), when the interior lighting system determines that a user in the front passenger area is conversing with the in-vehicle voice assistant, the interior lighting system may activate ambient lighting in the front passenger area. For example, the interior lighting system may control the instrument panel ambient strip light, the indirect instrument panel ambient lighting, the door panel ambient strip light, the indirect door panel ambient lighting, and the indirect auxiliary instrument panel ambient lighting to be illuminated in the front passenger area.

[0142] 5(c), when the interior lighting system determines that a user in the second row left area is conversing with the in-vehicle voice assistant, the interior lighting system may activate ambient lighting in the second row left area. For example, the interior lighting system may control the door panel ambient strip light, the indirect light of the door panel ambient lighting, the seat back ambient strip light, and the indirect light of the footwell ambient lighting in the second row left area to be turned on.

[0143] 5(d), when the interior lighting system determines that a user in the second row right area is conversing with the in-vehicle voice assistant, the interior lighting system may activate ambient lighting in the second row right area. For example, the interior lighting system may control the door panel ambient strip light, the indirect light of the door panel ambient lighting, the seat back ambient strip light, and the indirect light of the footwell ambient lighting in the second row right area to be turned on.

[0144] 6 is a schematic flowchart of a method for controlling distributed speech environment lighting according to an embodiment of the present application. As shown in FIG. 6, the method for controlling distributed speech environment lighting may include the following steps:

[0145] S601: A microphone collects speech signals from a user.

[0146] For example, the areas within the vehicle may be divided into a driver's area, a front passenger's area, a second-row left area, and a second-row right area. Each area may include a corresponding microphone. When the vehicle's voice assistant is in a non-wake-up state, the microphones in each area of ​​the vehicle may be in an audio collecting state.

[0147] It should be understood that in the embodiments of this application, the areas within the vehicle may be divided into a driver's area, a front passenger's area, a second-row left-hand area, and a second-row right-hand area, or may be divided in another manner. This is not limited to the embodiments of this application. For example, the areas within the vehicle may be divided into a driver's area, a front passenger's area, a second-row left-hand area, a second-row center area, and a second-row right-hand area, or the areas within the vehicle may be divided into a driver's area, a front passenger's area, a second-row left-hand area, a second-row right-hand area, and a rear trunk area. When the vehicle includes a third row of seats, the areas within the vehicle may be divided into a driver's area, a front passenger's area, a second-row left-hand area, a second-row right-hand area, a third-row left-hand area, and a third-row right-hand area. In another example, a five-seat sedan may be divided into a front row area and a rear row area. In another example, a seven-seat SUV may be divided into a front row area, a middle row area, and a rear row area. In another example, a passenger car may be divided into a driver's area, a front passenger compartment area, a middle passenger compartment area, and a rear passenger compartment area. In another example, a vehicle may be divided into an interior area and an exterior area. In another example, the area division scheme may be a combination of the different area division schemes described above. It should be understood that when the areas are divided in different schemes, the number of sensors may also be different.

[0148] In an embodiment, after detecting that a user taps the voice wake-up button, the vehicle may control a microphone in the interior lighting system to collect a voice signal from the user. In an embodiment of this application, the voice button may be located on the steering wheel in the driver's area, on the large center console screen, or in the second row left area or the second row right area. This is not limited to the embodiment of this application.

[0149] S602: The microphone transmits the collected speech signal to the VIU.

[0150] For example, referring to the schematic diagram of the structure of an interior vehicle lighting system shown in Figure 4, microphone 1 may be a microphone in the driver's area, microphone 2 may be a microphone in the front passenger area, microphone 3 may be a microphone in the second row left area, and microphone 4 may be a microphone in the second row right area. Microphone 1 may transmit captured speech signal 1 to VIU 1, microphone 2 may transmit captured speech signal 2 to VIU 2, microphone 3 may transmit captured speech signal 3 to VIU 3, and microphone 4 may transmit captured speech signal 4 to VIU 4.

[0151] S603: The VIU transfers the speech signal to the ring network.

[0152] S604: After acquiring the speech signal on the ring network, the CDC may publish a speech state signal carrying location information on the ring network based on the speech signal.

[0153] For example, VIU1, VIU2, VIU3, and VIU4 may publish the corresponding speech signals on the ring network after receiving them. After receiving speech signal 1, speech signal 2, speech signal 3, and speech signal 4, the CDC may determine the area from which the user will transmit the speech signal. For example, based on the signal strengths of speech signal 1, speech signal 2, speech signal 3, and speech signal 4, the CDC may determine that the speech signal with the highest signal strength is speech signal 1. Because speech signal 1 is the speech signal collected by microphone 1 and published on the ring network by VIU1, the CDC may determine that the speech signal is the speech signal collected by a microphone in the driver's area. Therefore, the CDC can publish a signal carrying location information of the driver's area (e.g., the signal may include a speech state signal in lighting signal mode 1, where lighting signal mode 1 turns on the ambient light) on the ring network.

[0154] S605: The VIU drives corresponding ambient lighting based on the speech state signal carrying the position information.

[0155] In an embodiment, each area may correspond to a VIU. For example, VIU1 may correspond to the driver's area, VIU2 may correspond to the front passenger area, VIU3 may correspond to the second-row left area, and VIU4 may correspond to the second-row right area. After the CDC publishes a signal carrying the location information of the driver's area on the ring network, VIU4 may first receive the signal carrying the location information of the driver's area. Because VIU4 corresponds to the second-row right area, after receiving the signal carrying the location information of the driver's area, VIU4 may forward the signal to VIU1 without performing any operation. Because VIU1 corresponds to the driver's area, after receiving the signal carrying the location information of the driver's area, VIU1 may execute a corresponding voice command (e.g., execute a command corresponding to lighting signal mode 1) and turn on interior light 1.

[0156] In an embodiment, the VIU also corresponds to ambient lighting identifier information. For example, Table 1 shows the correspondence between the VIU and ambient lighting identifier information.

[0157] [Table 1]

[0158] It should be understood that the correspondence between the VIU and the ambient lighting identifier information shown in Table 1 is merely an example, and the embodiments of this application are not limited thereto.

[0159] For example, the CDC may publish a signal carrying ambient lighting identifier information 1 and ambient lighting identifier information 2 (e.g., a speech state signal including lighting signal mode 2, where lighting signal mode 2 is a flowing water lighting from left to right) on the ring network. After the CDC publishes the signal carrying ambient lighting identifier information 1 and ambient lighting identifier information 2 on the ring network, the VIU4 may first receive the signal carrying ambient lighting identifier information 1 and ambient lighting identifier information 2. Because the VIU4 does not correspond to the ambient lighting identifier 1 and ambient lighting identifier 2, after receiving the signal carrying ambient lighting identifier information 1 and ambient lighting identifier information 2, the VIU4 may forward the speech state signal to the VIU1 without performing any operation. Because the VIU1 corresponds to the ambient lighting identifier 1 and ambient lighting identifier 2, after receiving the signal carrying ambient lighting identifier 1 and ambient lighting identifier 2, the VIU1 may execute a corresponding voice command (e.g., execute a command corresponding to the lighting signal mode 2) to drive the instrument panel ambient lighting in the driver's area to be displayed in a flowing water lighting format.

[0160] In an embodiment of this application, the in-vehicle lighting system may activate ambient lighting in a corresponding area when it determines that a user in the area is conversing with the in-vehicle voice assistant. In this manner, when the in-vehicle voice assistant is in the wake-up state, listening state, think-aloud state, and execution state, the user activates the respective ambient lighting in the corresponding area.

[0161] In an embodiment, after a user located in the driver's area, the front passenger area, the second row left area, or the second row right area wakes up the voice assistant, the interior lighting system may turn on the ambient lighting in the corresponding area, and in different states, the interior lighting system may execute lighting signals corresponding to speech states. For example, lighting signal mode 1 is executed in the speech wake-up state, lighting signal mode 2 is executed in the speech listening state, lighting signal mode 3 is executed in the speech thinking state, and lighting signal mode 4 is executed in the speech execution state.

[0162] FIG. 7 is a schematic flowchart of a method for controlling distributed speech ambient lighting according to an embodiment of this application. In a process in which the in-vehicle lighting control system detects that a user in the driver's area has woken up the voice assistant by speaking or using a button, the CDC may determine that the voice assistant is currently in a speech-wakeup state. The CDC may publish a speech status signal 1 carrying location information of the driver's area on the ring network, and the VIU 1 may execute a lighting signal mode 1 to turn on ambient lighting 1. After the voice assistant is woken up and before the CDC receives a new speech signal, the CDC may publish a speech status signal 2 carrying location information of the driver's area on the ring network, and the VIU 1 may execute a lighting signal mode 2 to turn on ambient lighting 2. After the CDC receives a speech signal including a speech command and before the CDC outputs corresponding speech feedback, the CDC may publish a speech status signal 3 carrying location information of the driver's area on the ring network, and the VIU 1 may execute a lighting signal mode 3 to turn on ambient lighting 3. In the process of the CDC outputting speech feedback to the user, the CDC may publish a speech status signal 4 on the ring network, which carries the location information of the driver area, and the VIU1 may execute the lighting signal mode 4 to turn on the ambient lighting 4.

[0163] For example, when the voice assistant is not woken up, the interior ambient lighting may be in an off state. When the microphone collects a speech signal carrying a wake-up phrase from the user, "Celia, Celia," the microphone may transmit the collected speech signal to the VIU, and the VIU publishes the collected speech signal on the ring network. When receiving the speech signal carrying the wake-up phrase, the CDC may determine that the speech signal includes the wake-up phrase. The CDC may perform a wake-up speech (e.g., the CDC may notify the user by using the utterance "Master, I'm here!") and transmit a speech status signal 1 carrying location information of the driver's area on the ring network. The speech status signal 1 indicates that red ambient lighting should be turned on in the driver's area. When receiving the speech status signal 1, the VIU 1 may control the ambient lighting in the driver's area to be turned on and control the color of the ambient lighting to be red.

[0164] After the voice assistant is woken up and before the CDC receives the speech signal carrying the speech command, the CDC may publish a speech state signal 2 carrying the driver's location information on the ring network. The speech signal state 2 indicates switching the color of the ambient lighting from red to blue. After receiving the speech state signal 2, the VIU1 may control the color of the ambient lighting in the driver's area to switch from red to blue.

[0165] When the microphone detects a speech signal carrying a speech command sent by a user, such as "Can you play song 1 by singer xx?", the microphone may transmit the speech signal to the VIU, and the VIU publishes the speech signal on the ring network. When the CDC receives the speech signal carrying the speech command, the speech thought state is enabled. In this case, the CDC may publish a speech state signal 3 carrying the driver's location information on the ring network. The speech state signal 3 indicates switching the color of the ambient lighting from blue to purple. Upon receiving the speech state signal 3, the VIU1 may control the color of the ambient lighting in the driver's area to switch from blue to purple. In addition, the CDC analyzes the user's intent and slot by using an automatic speech recognition (ASR) module and a natural language processing (NLU) module in the speech engine.

[0166] For example, the information obtained by converting speech into text by the ASR module is "Please play song 1 by singer xx for me." From this sentence, the NLU module can obtain the content shown in Table 2 through analysis.

[0167] [Table 2]

[0168] After obtaining the user's intention and slot, the CDC may perform a corresponding action (e.g., play song 1) and publish a speech state signal 4 on the ring network, which carries the driver's location information. The speech state signal 4 indicates switching the color of the ambient lighting from purple to green. Upon receiving the speech state signal 4, the VIU1 may control the color of the ambient lighting in the driver's area to switch from purple to green.

[0169] In an embodiment, before playing song 1, the CDC may further inform the user by using the utterance "Master, song 1 is ready to play for you."

[0170] It should be understood that the above is described by using an example in which the interior lighting system can switch between different colors of ambient lighting in different speech states. The embodiments of this application are not limited thereto. For example, in the speech wake-up state, the interior lighting system may further turn on red ambient lighting in the driver's area by using a breathing light; in the speech listening state, the interior lighting system may further turn on red ambient lighting in the driver's area by using a flowing water light; in the speech thinking state, the interior lighting system may further turn on blue ambient lighting in the driver's area by using a flowing water light; and in the speech execution state, the interior lighting system may further turn on blue ambient lighting in the driver's area by using a breathing light.

[0171] In an embodiment, the change modes of the ambient lighting in different speaking states may be preset or may be set by the user, which is not limited in the embodiment of this application.

[0172] In an embodiment, before controlling the vehicle lighting in the area to operate, the interior-vehicle lighting system may further acquire user information of the area, and based on the user information, acquire a matching relationship between the user information and a vehicle lighting operation mode. The interior-vehicle lighting system may control the vehicle lighting in the area to operate in a certain mode based on the matching relationship. For example, a passenger in the front passenger area may send a voice command, and the interior-vehicle lighting system may determine that the user in the front passenger area is User A based on image information collected by a camera. The interior-vehicle lighting system may acquire a vehicle lighting operation mode preferred by User A. For example, Table 3 shows the correspondence relationship between preferred vehicle lighting display modes and different users.

[0173] [Table 3]

[0174] It should be understood that the correspondence between users and preferred vehicle lighting operation modes shown in Table 3 is merely an example, which is not limited to the embodiments of this application.

[0175] For example, when the interior vehicle lighting system determines, based on user information of the front passenger area collected by the camera, that the user in the front passenger area is User A and that User A is currently interacting with the in-vehicle voice assistant, the interior vehicle lighting system may control the vehicle lights in the front passenger area to glow red.

[0176] In an embodiment, if the signal acquired by the interior vehicle lighting system and collected by the microphone in an area is an audio signal, the interior vehicle lighting system may further control to operate the interior lights in the area based on parameters of the audio signal. For example, User B on the left in the second row is playing Song 1 on his mobile phone. After acquiring the audio signal corresponding to Song 1, the interior vehicle lighting system may control to operate the vehicle lights on the left in the second row based on the meter (or rhythm) and mood (e.g., happy or sad) of Song 1, the type of song (e.g., rock, country, heavy metal, pop, or folk), or the color of the album cover of Song 1.

[0177] For example, the time signature of Song 1 may be "1234567" in the number profile in the musical score of Song 1 (the corresponding letter profile expresses "DO RAI MI FA SO LA XI"), which may correspond to different vehicle lighting colors. During the playback process of Song 1, the in-vehicle lighting system may determine the corresponding ambient lighting color based on the number profile corresponding to the lyrics, so as to control the change of the ambient lighting color.

[0178] For example, the interior vehicle lighting system may determine the mood of the current song based on the lyrics of song 1. For example, song 1 is a happy song or a sad song. If song 1 is a happy song, the interior vehicle lighting system may control the ambient lighting on the left side of the second row to display a warm color tone. If song 1 is a sad song, the interior vehicle lighting system may control the ambient lighting on the left side of the second row to display a cool color tone.

[0179] For example, the interior vehicle lighting system may further control the left side vehicle lighting of the second row to operate based on the type of song 1. The interior vehicle lighting system may obtain a correspondence between different types of music and vehicle lighting operation modes. For example, when song 1 is rock music, the interior vehicle lighting system may control the left side ambient lighting of the second row to be displayed in a flowing water lighting format. In another example, when song 1 is folk music, the interior vehicle lighting system may control the left side ambient lighting of the second row to display a warm color tone, or when song 1 is heavy metal music, the interior vehicle lighting system may control the left side ambient lighting of the second row to display a cool color tone.

[0180] In an embodiment, the correspondence between the parameters of the audio signal and the vehicle lighting operation mode may be set before delivery of the vehicle or may be set by a user, which is not limited to the embodiments of this application.

[0181] In an embodiment, the audio signal may be music, and the interior vehicle lighting system may determine first information of the music based on a first parameter of the audio signal, and the first information may be one or more of a song title, an artist name, or the name of an album on which the music is located.

[0182] For example, the interior vehicle lighting system may determine a song title corresponding to the music based on lyric information in the audio signal, and control the operation of the vehicle lighting in the corresponding area based on the mapping relationship between the song title and the vehicle lighting operation mode.

[0183] In an embodiment of this application, the in-vehicle lighting system can determine the area where the user is conversing with the voice assistant in a timely manner to drive ambient lighting in the corresponding area. The user can quickly understand and determine the area where the voice assistant should select to converse with the user based on changes in ambient lighting in different areas. This can provide a sense of face-to-face communication for users in different areas, fully consider the moods of the occupants in the vehicle, and improve the experience of human-machine interaction.

[0184] The above describes a schematic diagram of the effect of ambient lighting in a distributed speech scenario with reference to Figures 5 to 7. The following illustrates the process by which ambient lighting changes with temperature according to an embodiment of this application with reference to Figures 8 to 11.

[0185] 8 is a schematic flowchart of changing ambient lighting with temperature according to an embodiment of this application. An interior vehicle lighting system may obtain a reference temperature T. When the temperature T of an area is lower than the reference temperature T, the ambient lighting around the area may be blue, and the color may gradually darken as the temperature cools, or when the temperature T of an area is higher than the reference temperature T, the ambient lighting around the area may be red, and the color may gradually darken as the temperature warms.

[0186] In this embodiment of the application, the color of the ambient lighting may change with the temperature in the area, allowing the user to intuitively feel the temperature change in the area where the user is located, thereby helping the user to accurately control the temperature of the area.

[0187] In an embodiment, the reference temperature may be preset or may be set by a user, which is not limited in the embodiments of this application.

[0188] In an embodiment, the interior lighting system may further acquire reference temperatures of different areas, for example, a reference temperature T0 of the driver area, a reference temperature T1 of the front passenger area, a reference temperature T2 of the second-row left area, and a reference temperature T3 of the second-row right area. The second-row left area is used as an example. When the temperature T of the second-row left area is higher than the reference temperature T2, the ambient lighting around the second-row left area may be blue, and the color may gradually darken as the temperature cools; or when the temperature T of the second-row left area is higher than the reference temperature T2, the ambient lighting around the area may be red, and the color may gradually darken as the temperature warms.

[0189] In this embodiment of the application, users in different areas may have different reference temperatures, which can meet the requirements of users in different areas. For example, an elderly person may expect the temperature of the area not to be too low, so the user may set the reference temperature of the area where the elderly person is located to 28°C. In this way, when the temperature of the area where the user is located is lower than the reference temperature, the indoor ambient light may turn blue to notify the user that the temperature is too low, so that the user can adjust the temperature of the area where the user is located. A young person may expect the temperature of the area not to be too high, so that the user may set the reference temperature of the area where the young person is located to 23°C. In this way, when the temperature of the area where the user is located is higher than the reference temperature, the indoor ambient light may turn red to notify the user that the temperature is higher than the reference temperature, so that the user can adjust the temperature of the area where the user is located.

[0190] In an embodiment, referring to the schematic diagram of the structure shown in FIG. 4 , the vehicle may be divided into a driver's area, a front passenger's area, a second-row left-hand area, and a second-row right-hand area. Temperature sensor 1 is disposed in the driver's area, temperature sensor 2 is disposed in the front passenger's area, temperature sensor 3 is disposed in the second-row left-hand area, and temperature sensor 4 is disposed in the second-row right-hand area. Temperature sensor 1, temperature sensor 2, temperature sensor 3, and temperature sensor 4 may transmit detected temperature values ​​1, 2, 3, and 4, respectively, to the VIU. After receiving the temperatures detected by the temperature sensors, the VIU may publish signals corresponding to temperature value 1, temperature value 2, temperature value 3, and temperature value 4 on the ring network.

[0191] If the CDC obtains a reference temperature T0, after receiving signals corresponding to multiple temperature values, the CDC may separately determine whether the temperature values ​​are higher than the reference temperature. For example, when the CDC determines that temperature value 1 is higher than reference temperature T0, the CDC may publish a signal carrying location information of the driver's area on the ring network. After receiving the signal carrying location information of the driver's area, VIU1 may drive the ambient lighting around the driver's area to turn red.

[0192] If the CDC acquires the reference temperatures of multiple different areas, after receiving signals corresponding to multiple temperature values, the CDC can separately compare the temperature detected by the temperature sensor in a certain area with the reference temperature of that area. For the specific process, please refer to the description in the previous embodiment. The details will not be described again here.

[0193] It should be understood that the above embodiment provides an explanation by using an example in which the color of the ambient lighting is red when the temperature is higher than the reference temperature, and the color of the ambient lighting is blue when the temperature is lower than the reference temperature. This is not limited to the embodiment of this application. For example, a user may further set the color (or change mode) of the ambient lighting when the temperature of the area is higher than the reference temperature and the color (or change mode) of the ambient lighting when the temperature of the area is lower than the reference temperature.

[0194] It should further be appreciated that for a schematic representation of the effect of ambient lighting varying with temperature, reference is made to the schematic representation of the effect depicted in FIG.

[0195] In an embodiment, before controlling the vehicle lighting in a corresponding area to operate, the interior lighting system may further first obtain user information for the area. The user information may be user identification information. For example, the interior lighting system may determine that the user in the driver's area is User A based on image information collected by a camera.

[0196] The interior vehicle lighting system may determine a vehicle lighting change mode preferred by user A. For example, the interior vehicle lighting system may obtain a correspondence between each of a plurality of users and an ambient lighting change mode preferred by the user. For example, user A prefers red ambient lighting when the temperature value of the area where user A is located is higher than a preset temperature value, or user A prefers blue ambient lighting when the temperature value of the area where user A is located is lower than the preset temperature value. In another example, user B prefers orange ambient lighting when the temperature value of the area where user B is located is higher than the preset temperature value, or user B prefers purple ambient lighting when the temperature value of the area where user B is located is lower than the preset temperature value.

[0197] In this case, when the temperature value of the driver area is higher than a preset temperature value and it is determined that the user in the driver area is user A, the in-vehicle lighting system controls the ambient lighting in the driver area to turn red.

[0198] In an embodiment, the correspondence between user information and the ambient lighting change mode preferred by the user may be associated with information about the logged-in account in the vehicle. When user A drives another vehicle, if he logs in to the vehicle by using the account, the vehicle may also obtain the correspondence accordingly. In this way, the user does not need to set the correspondence in each vehicle, which helps to reduce user operations and improve user experience.

[0199] 9 is a schematic flowchart of changing ambient lighting with user-adjusted temperature according to an embodiment of the present application. A user in an area may adjust the temperature by using an in-vehicle voice assistant, a large center console screen, or a temperature adjustment knob. When the adjusted temperature T is higher than the current in-vehicle temperature T4, the in-vehicle lighting system may determine that the user currently intends to warm the temperature and drive the ambient lighting in the area to change to a warmer tone; or when the adjusted temperature T is lower than the current in-vehicle temperature T4, the in-vehicle lighting system may determine that the user currently intends to cool the temperature and drive the ambient lighting in the area to change to a cooler tone.

[0200] In embodiments, when the adjusted temperature is higher than the current vehicle interior temperature, the higher the adjusted temperature value, the darker the color may be. When the adjusted temperature is lower than the current vehicle interior temperature, the lower the adjusted temperature value, the darker the color may be.

[0201] In an embodiment, the interior vehicle lighting system may further store a correspondence between temperature values ​​and corresponding ambient lighting colors. For example, Table 4 shows the correspondence between temperature values ​​and ambient lighting colors.

[0202] [Table 4]

[0203] It should be understood that Table 4 is merely an example, and the correspondence between the temperature value and the color of the ambient lighting is not specifically limited in the embodiments of this application. For example, there may also be a correspondence between the temperature range and the color of the ambient lighting, for example, [20°C, 22°C) corresponds to blue, [22°C, 24°C) corresponds to green, [24°C, 26°C) corresponds to purple, [26°C, 28°C) corresponds to orange, and [28°C, 30°C) corresponds to red. In this way, after the user adjusts the temperature, the in-vehicle lighting system may drive the ambient lighting to display the color corresponding to the adjusted temperature.

[0204] It should further be understood that for a schematic diagram of the effect of ambient lighting changing with temperature adjusted by the user, reference is made to the schematic diagram of the effect depicted in FIG.

[0205] It should be further understood that the vehicle interior lighting system can further control the vehicle lighting to operate based on user preferences. For specific control processes, please refer to the descriptions in the above embodiments. Details will not be described again here.

[0206] In an embodiment, when a user adjusts the temperature of the air conditioner in the driver's area to T and the vehicle detects that the temperature is lower than the current vehicle interior temperature T4, the vehicle may further continue to detect that the exhaust direction of the air conditioner outlet is a first direction. In this case, the interior lighting system may control the ambient lighting in the driver's area to be displayed in a flowing water lighting style, where the flowing water lighting style coincides with the first direction. For example, if the vehicle detects that the exhaust direction of the air conditioner outlet in the driver's area is from the front passenger area to the driver's area, the interior lighting system may control the flowing water lighting on the steering wheel to present a flowing water lighting style from right to left.

[0207] 10 is a schematic flowchart of changing ambient lighting with the temperature of the liquid in the cup according to an embodiment of the present application. The interior vehicle lighting system may further include cup holder ambient lighting, which may notify the user of changes in the temperature of the liquid in the cup by using color changes. For example, a cold drink may also be displayed in blue, and a hot drink may be displayed in red, so that the user knows the temperature of the liquid in the cup at any time.

[0208] A temperature sensor at the bottom of the cup holder detects the difference between the temperature T of the liquid in the cup and the temperature T5 before the cup was placed. If T is higher than T5, the temperature of the liquid in the cup after placing it is warmer compared to the temperature before placing it, and the cup holder ambient lighting can be changed to a warmer tone (e.g., red). Further, higher temperatures indicate darker colors. The temperature sensor at the bottom of the cup holder can continue to detect the temperature T of the liquid in the cup after placing it. As the temperature of the liquid in the cup gradually cools, the color of the cup holder ambient lighting changes from dark to light (e.g., as the temperature gradually cools, the color of the ambient lighting changes from dark red to light red).

[0209] If T is lower than T5, the temperature of the liquid in the cup after placing it will cool compared to the temperature before placing it, and the cup holder ambient lighting may change to a cooler tone. Additionally, lower temperatures indicate darker colors. A temperature sensor at the bottom of the cup holder may continue to detect the temperature T of the liquid in the cup after placing it. As the temperature of the liquid in the cup gradually warms, the color of the cup holder ambient lighting changes from dark to light (e.g., as the temperature gradually warms, the color of the ambient lighting changes from dark blue to light blue).

[0210] In this embodiment of the application, after a hot or cold drink is placed in the cup holder, the user can be informed of the temperature of the liquid in the cup by using the change in color of the cup holder ambient lighting. For example, when the user sees that the cup holder ambient lighting is dark red, the user can avoid touching the cup, thereby avoiding the user from being burned. In the process of the hot drink cooling down to room temperature or the cold drink warming up, the color of the cup holder ambient lighting can gradually change from dark to light, thereby allowing the user to know the changing state of the temperature of the liquid in the cup in a timely manner.

[0211] FIG. 11 is a schematic illustration of the effect of ambient lighting varying with the temperature of the liquid in the cup.

[0212] The above describes the process in which the ambient lighting changes with temperature according to an embodiment of this application with reference to Figures 8 to 11. The following describes the process in which the ambient lighting changes with the user's driving intention in the user's driving process with reference to Figures 12 to 15.

[0213] 12 is a schematic flowchart of changing ambient lighting as a vehicle turns, according to an embodiment of this application. For example, when a vehicle's navigation system indicates that a turn (e.g., a left turn, a right turn, or a U-turn) is required, the strip lights on the left and right sides of the instrument panel may flash in advance or indicate by using a flowing water pattern from left to right to notify the user that the vehicle is about to turn. For example, when a user is notified through navigation that they will turn left, the interior lighting system may drive the ambient strip light on the left side of the instrument panel to flash or to be displayed in a flowing water pattern. In another example, when a user is notified through navigation that they will turn right, the interior lighting system may drive the ambient strip light on the right side of the instrument panel to flash or to be displayed in a flowing water pattern.

[0214] For example, referring to the schematic diagram of the structure shown in Figure 4, when the CDC manual navigation information or the MDC automatic navigation information indicates that the vehicle is about to turn left, the CDC or MDC may publish a signal carrying the left turn information on the ring network. Upon receiving the signal carrying the left turn information, the VIU may drive the ambient strip light on the left side of the instrument panel to flash or to be displayed in a flowing water lighting format.

[0215] It should be understood that this scenario is applicable to automated or manual driving. The interior lighting system uses navigation turn information to drive ambient lighting to notify the user by flashing in advance or using flowing lighting.

[0216] In an embodiment, the in-vehicle lighting system may drive ambient lighting by referring to turning information and distance information in navigation. For example, when the distance to the intersection where a turn should be made reaches a preset distance (e.g., 20 meters), the ambient lighting may be driven to flash in advance, or the user may be notified by using flowing water lighting.

[0217] Figure 13 is a flowchart of the effect of ambient lighting changing as the vehicle turns. As shown in Figure 13(a), when the vehicle is about to turn left, the ambient strip light on the left side of the instrument panel flashes. As shown in Figure 13(b), when the vehicle is about to turn right, the ambient strip light on the right side of the instrument panel flashes.

[0218] 14 is a schematic flowchart of changing ambient lighting with the acceleration / deceleration state of a vehicle according to an embodiment of this application. Autonomous driving is used as an example. When an autonomous vehicle accelerates, the interior ambient lighting may gradually become warmer, or when an autonomous vehicle decelerates, the interior ambient lighting may gradually become cooler. As the vehicle accelerates and decelerates, the ambient lighting changes color in real time or is displayed in a flowing water-like lighting format. For example, a higher vehicle speed indicates a higher flowing water speed.

[0219] It should be understood that this scenario is also applicable to manual driving: the user is informed of the vehicle's acceleration / deceleration status by using changes in cool / warm tones of the interior ambient lighting.

[0220] FIG. 15 is a schematic diagram of the effect of ambient lighting changing with the acceleration / deceleration state of a vehicle according to an embodiment of the present application.

[0221] In an embodiment, in the process of autonomous driving, if the vehicle needs to be taken over by the driver or auxiliary driving warning information such as autonomous emergency braking (AEB) emergency braking occurs, the interior lighting system may drive the interior ambient lighting to flash to notify the user.

[0222] In this embodiment of the application, the ambient lighting actively detects the intention of autonomous driving operations in an autonomous driving scenario and notifies the driver in advance through lighting signals, which enhances human-machine mutual trust and relieves the psychological burden of the passengers.

[0223] The above describes the process of changing ambient lighting along with the user's driving intention during the user's driving process with reference to Figures 12 to 15. The following describes the process of implementing blind spot prompts by using ambient lighting with reference to Figures 16 to 18.

[0224] 16 is a schematic flowchart of implementing blind spot prompts in the driving process by using ambient lighting according to an embodiment of this application. In the driving process of a vehicle, after the vehicle performs a left or right turn and detects that there is a vehicle approaching from behind, the ambient lighting in the instrument panel may be emitted from the instrument panel in the form of flowing water lighting, flowing left from the instrument panel to the left door panel, or flowing right to the right side of the instrument panel, in order to guide the driver's eyes to the rearview mirror. This improves the driver's attention.

[0225] For example, when a vehicle turns left, the left rear radar can transmit collected data to the corresponding VIU. The VIU publishes a signal corresponding to the data on the ring network. After receiving the signal, the VDC can determine the distance information of the vehicle approaching from behind. When the distance information meets a preset condition (e.g., the distance between the vehicle approaching from behind and the current vehicle is 10 meters or less), the VDC can publish a signal on the ring network to present a left flow from the instrument panel to the left door panel. In this way, when the VIU receives the signal, the ambient lighting on the left side of the instrument panel can be driven to flow to the left door panel.

[0226] 17 is a flowchart showing the effect of using ambient lighting to implement blind spot prompts during the driving process. As shown in FIG. 17, when the vehicle is turning left and the distance to the vehicle approaching from behind meets a preset condition, the ambient strip light on the left side of the instrument panel emits a flowing light pattern from the instrument panel and flows leftward to the left door panel. When the vehicle is turning right and the distance to the vehicle approaching from behind meets a preset condition, the ambient strip light on the right side of the instrument panel emits a flowing light pattern from the instrument panel and flows rightward to the right door panel.

[0227] 18 is a diagram illustrating the effect of implementing a prompt for door-opening collision avoidance by using ambient lighting according to an embodiment of this application. When a vehicle stops, the ambient lighting on the vehicle door indicates the status of a pedestrian or vehicle approaching from behind. For example, when the ambient lighting on the vehicle door is lit, it indicates that a pedestrian or vehicle is passing, and the vehicle door is automatically locked and cannot be opened in this case. After the pedestrian or vehicle has passed, the ambient lighting on the vehicle door is turned off, and the vehicle door is automatically unlocked.

[0228] In an embodiment, collision avoidance prompts can be implemented by using a change in the color of the ambient lighting on the vehicle door. For example, when the ambient lighting on the vehicle door lights up and glows red, it indicates that a pedestrian or vehicle is passing, and the vehicle door is automatically locked and cannot be opened. After the pedestrian or vehicle passes, the ambient lighting on the vehicle door changes from red to green, and the vehicle door is automatically unlocked.

[0229] In an embodiment, if an alert is triggered in sentry mode, the interior ambient lighting may flash as a warning light (eg, flashing red / blue warning lights).

[0230] In an embodiment, when the vehicle is stationary and the position information of an object around the first vehicle door satisfies a preset condition, the interior vehicle lighting system may control the first vehicle light to operate. The first vehicle light is the vehicle light in a first area where the first vehicle door is located. For example, the preset condition may be that the distance between the object around the first vehicle door and the first vehicle door is equal to or less than a preset distance (e.g., 1 m).

[0231] In an embodiment, when the vehicle is stationary, position information of objects around a first vehicle door satisfies a preset condition, and the vehicle detects a user attempting to open the vehicle door, the interior vehicle lighting system may control the first vehicle light to operate. For example, the vehicle may collect image information by using a camera and determine that the user is attempting to open the first vehicle door based on the collected image information. For example, the first vehicle door may have a touch sensor on the door handle. When the touch sensor detects the user's touching action, the touch sensor may determine that the user is attempting to open the first vehicle door.

[0232] In an embodiment, before the interior lighting system controls the first vehicle light to operate, the interior lighting system may further determine whether the first area includes a user. For example, the interior lighting system may determine whether a user is present in the current first area based on image information collected by a camera. As another example, the interior lighting system may further determine whether a user is present in the current first area by using a pressure sensor under the seat in the first area. If the user is present in the first area, the interior lighting system may control the first vehicle light to operate when the vehicle is stationary and position information of objects around the first vehicle door meets a preset condition. If the user is not present in the first area, the interior lighting system may control the first vehicle light not to be turned on (or not to operate). This can effectively avoid wasting power.

[0233] In an embodiment, when the interior vehicle lighting system controls the first vehicle light to operate, the vehicle may further lock the first vehicle door.

[0234] In an embodiment, the first vehicle lighting includes a first interior light and a first exterior light. Controlling the first vehicle light by the interior lighting system includes controlling the first interior light to operate in a first mode and controlling the first exterior light to operate in a second mode. The first mode notifies a user inside the vehicle that an object outside the first vehicle door is passing, and the second mode notifies a user outside the vehicle that the user is about to open the vehicle door. For example, when the vehicle is stationary and position information of the object outside the first vehicle door meets a preset condition, the interior lighting system may control the first interior light in the first area to glow red. In this way, a user inside the vehicle can be notified that an object is passing outside the vehicle door, thereby warning the user inside the vehicle. In addition, the interior lighting system may control the first exterior light to display yellow. In this way, pedestrians or vehicles outside the vehicle can be notified that the first door of the vehicle is about to open, thereby causing the pedestrians or vehicles outside the vehicle to move away from the first door.

[0235] In an embodiment, before controlling the first vehicle light to operate, the interior vehicle lighting system may further acquire user information (e.g., user identification information) within the first area, and based on the user information, read a preset matching relationship between the user information and the vehicle light operation mode, and through the matching, further control the first vehicle light to operate in the acquired operation mode. For example, the pre-warning color preferred by user A is red, and the pre-warning color preferred by user B is purple. In this case, when the vehicle is stationary and the position information of the objects around the first vehicle door satisfies a preset condition, the interior vehicle lighting system may determine that the user within the first area is user B based on image information acquired by the camera, and further determine that the pre-warning color preferred by user B is purple based on the matching relationship. The interior vehicle lighting system may control the first interior light within the first area to display purple, thereby providing an advance warning to user B.

[0236] The above describes the process of implementing blind spot prompting by using ambient lighting with reference to Figures 16 to 18. The following describes the process of indoor tracking spotlight illumination with reference to Figures 19 to 21.

[0237] The interior vehicle lighting system in the embodiment of this application may include a tracking spotlight, which may be one or more spotlights that can be freely rotated, or a matrix vector light emitting diode (LED) illumination light.

[0238] 19 is a schematic flowchart for controlling the illumination of an interior tracking spotlight according to an embodiment of this application. The state of an occupant in a vehicle can be determined based on data collected by a camera monitor system (CMS) so as to automatically activate the tracking spotlight for tracking illumination. For example, when a user retrieves an item from the rear trunk at night, the CMS may determine the position of the user's hand based on image information collected by a camera so that the tracking spotlight can track the hand movement and actively illuminate it. In another example, when a user in an area retrieves a book or a cell phone, the CMS may determine the position of the book or the cell phone based on image information collected by a camera so that the tracking spotlight can track the direction of the book or the cell phone and actively illuminate it. In another example, when a user in an area looks down to pick up an item, the interior vehicle lighting system may determine to turn on the footwell ambient lighting in the area.

[0239] It should be understood that the CMS may determine the position of the user's hand, the position of the book or mobile phone in the user's hand based on the image information collected by the camera, and the process of the user looking down to pick up an object may be realized in the manner of conventional technology.

[0240] FIG. 20 is a diagram of the effect of controlling the illumination of an indoor tracking spotlight.

[0241] In an embodiment, the interior lighting system is associated with an application (app) such as a mobile phone game or a mobile phone singing app, and the lighting effects can change along with the melody of the game or song, thereby creating an immersive gaming or singing atmosphere. The tracking spotlight included in the interior lighting system can further track outstanding passengers during the game or song, supporting the personality of the "protagonist." In a multiplayer game, if a player wins the game, the lighting signal in the corresponding seat flashes, indicating the game was successful.

[0242] For example, FIG. 21 is a diagram of another effect of controlling the lighting of an interior tracking spotlight. User A in the second row left area and user B in the front passenger area play the same game on their mobile phones. The interior vehicle lighting system may separately establish a connection between user A and user B to mobile phone 1 and to mobile phone 2, and determine that mobile phone 1 is located in the second row left area and mobile phone 2 is located in the second row right area based on distance and orientation information measured through short-range wireless communication (e.g., Bluetooth or Wi-Fi). When the player of mobile phone 1 wins the game, the tracking spotlight may illuminate user A.

[0243] In an embodiment, a camera outside the vehicle may collect a photograph of the scenery outside the vehicle. The environmental conditions of the road currently being driven on are recognized by using an image recognition algorithm. For example, the predominant colors in the scenery photograph may be extracted by using an algorithm, so that the interior lighting system can control the ambient lighting to display the corresponding color. For example, when a forest scene is recognized, the indoor ambient lighting displays the color of the forest (e.g., green); when an ocean scene is recognized, the indoor ambient lighting displays the color of the ocean (e.g., blue); and when a desert scene is recognized, the indoor ambient lighting displays the color of the desert (e.g., yellow).

[0244] In embodiments, the interior ambient lighting may be reverberant with the exterior decorative lighting to achieve a synchronized rhythm inside and outside the vehicle. For example, when the vehicle is in an accelerated state, the interior ambient lighting may be green and the exterior decorative lighting may also be green. In this way, users of other vehicles around the vehicle can determine that the vehicle is accelerating or decelerating, thereby providing advance warning to surrounding vehicles.

[0245] In an embodiment, the interior and exterior ambient lighting may be synchronized to indicate a driving assistance state or an autonomous driving state. For example, when the vehicle is in an autonomous driving state, the interior ambient lighting may be blue. In this case, the exterior decorative lighting may also be blue, so that other vehicles around the vehicle determine that the vehicle is in an autonomous driving state. Furthermore, when the vehicle needs to be taken over by the user, the vehicle may control the color of the interior ambient lighting to change from blue to red to notify the user inside the vehicle that the vehicle is currently being switched from an autonomous driving mode to a manual driving mode.

[0246] In an embodiment, the interior vehicle lighting system may write the current vehicle's intention as a lighting signal and implement the corresponding lighting signal by using the rear lighting. A vehicle approaching from behind can capture and analyze the lighting signal corresponding to the rear lighting of the vehicle in front by using a front camera, so that the intention of the vehicle in front can be displayed by using the interior lighting or a large screen of the vehicle approaching from behind, thereby achieving the purpose of vehicle communication; or the vehicle in front can capture the lighting from the vehicle approaching from behind by using a rear camera, so that the intention of the vehicle approaching from behind can be displayed by using the interior lighting or a large screen of the vehicle in front, thereby achieving the purpose of vehicle communication.

[0247] In an embodiment, the interior vehicle lighting system may further control the vehicle lighting to operate in different modes (e.g., theater mode, rest mode, game mode, and creativity mode).

[0248] For example, in theater mode, the interior vehicle lighting system may control changes in the interior ambient lighting based on color changes of a movie played on a large center console screen to give the user an immersive experience.

[0249] For example, in rest mode, the vehicle may control the brightness of the interior ambient lighting to be lowered. Additionally, the vehicle may adjust the seats, scents, and music within the vehicle to promote relaxation.

[0250] For example, in the creative mode, when the user composes music, the vehicle interior lighting system can control the ambient lighting to operate according to the beat (or rhythm) of the music, so that the reverberation effect inside the vehicle is good. For specific implementation, please refer to the description in the above embodiment. The details will not be described again here.

[0251] In an embodiment, the interior lighting system may further project exterior lighting based on user settings or a scenario selected by the user. For example, some photos may be projected onto a wall or road surface by using headlights. In another example, parking for playing a game, AR-HUD projection, and projection of vehicle lighting into the environment may interact with each other, thereby creating a gaming atmosphere.

[0252] In embodiments, the lighting system within the vehicle may further include decorative lighting. The lighting system may be configured based on the user's color, the color of the environment, or the user's mood and preferences. For example, the lighting system may control the ambient lighting to better match the user's clothing.

[0253] In embodiments, the vehicle may further create a friendliness effect by using a lighting system. For example, the lighting system may control the color, direction, and position of the lights to change with the user's identity / location. For example, the vehicle may detect that a user is walking around the vehicle, and ambient lighting may be turned on where the user passes, with the ambient lighting changing with the user's location.

[0254] 22 is a schematic flowchart of a lighting system control method 2200 according to an embodiment of the present application. The method 2200 is applied to a vehicle, the vehicle includes a plurality of areas, each of the plurality of areas includes at least one light-emitting device and at least one sensor of a first type, the plurality of areas includes a first area, the first area includes a first light-emitting device and a first sensor, and the type of the first sensor is a first type, and the method 2200 includes the following steps:

[0255] S2201: A vehicle acquires a first signal collected by a sensor in a first area.

[0256] S2202: The vehicle controls the first light emitting device to operate based on the first signal.

[0257] In an embodiment of the present application, a vehicle can control to operate lighting devices in a first area based on a first signal collected by a sensor located in the first area, which can give a sense of a form of face-to-face interaction to a user in the first area, fully consider the moods of occupants in different areas of the vehicle, and help improve the intelligence of the lighting system, thereby helping to improve the user experience.

[0258] Optionally, the plurality of interior lights may include exterior decorative lights, interior ambient lights, spotlights, or LED lights.

[0259] Optionally, controlling the vehicle to operate the first lighting device based on the first signal includes the vehicle adjusting ambient lighting based on sound, the sound including one or more of a user voice command, music played in the vehicle, and sound made when a video is played in the vehicle.

[0260] Optionally, the first type of sensor is a sound source positioning device, the first signal includes an acoustic signal and information about the sound source location, and controlling the vehicle to operate the first light-emitting device based on the first signal includes controlling the vehicle to operate the first light-emitting device when the sound source location is located in the first area.

[0261] Optionally, the sound source locator may be a microphone array.

[0262] Optionally, the first type of sensor is an acoustic collecting device, the plurality of areas further includes a second area, the second area includes a second sensor, and the type of the second sensor is the first type, and before controlling the vehicle to operate the first light-emitting device based on the first signal, the method further includes the vehicle obtaining a second signal collected by the second sensor, and controlling the vehicle to operate the first light-emitting device based on the first signal includes controlling the vehicle to operate the first light-emitting device when determining, based on the first signal and the second signal, that the sound source is located in the first area.

[0263] For example, as shown in FIG. 5A, the multiple areas may be a driver's area, a front passenger area, a second-row left area, and a second-row right area. When a user in the driver's area sends a voice signal, microphones in all four areas may collect the voice signal and transmit it to the controller. If the controller determines that the voice signal is sent by a user located in the driver's area, the controller may control the ambient lighting in the driver's area to operate. In this way, the vehicle can determine the area in which the voice assistant will communicate with the user in a timely manner by using sensors located in different areas. The interior lighting can provide a sense of face-to-face communication for the user, and the user can quickly understand and determine the area in which the voice assistant will select to communicate with the user based on changes in the interior lighting. This fully considers the mood of the occupants in the vehicle and improves the human-to-machine experience of voice communication.

[0264] Optionally, the first sensor and the second sensor may each be a microphone.

[0265] Optionally, the vehicle determining that the user is located in the first area based on the first signal and the second signal includes the vehicle determining that the user is located in the first area based on a signal strength of the first signal and a signal strength of the second signal.

[0266] Optionally, before controlling the vehicle to operate the first light-emitting device, the method further includes the vehicle determining a speech recognition state based on the first signal, and controlling the vehicle to operate the first light-emitting device includes the vehicle controlling the first light-emitting device to operate based on the speech recognition state.

[0267] In an embodiment of the present application, the vehicle can determine a speech recognition state based on the collected first signal, and different speech recognition states can correspond to different operating modes of the light-emitting device. In this way, in different speech recognition states, the user can determine the current speech recognition state of the voice assistant based on changes in the light-emitting device, thereby helping to improve the human-to-machine communication experience.

[0268] Optionally, the speech recognition state includes one or more of a speech wake-up state, a speech listening state, a speech thinking state, and a speech acting state.

[0269] It should be understood that the speech wake-up state, speech listening state, speech thinking state, and speech execution state refer to the descriptions in the preceding embodiments, and the details will not be described again here.

[0270] Optionally, the first type of sensor is an acoustic collecting device, and wherein the vehicle obtaining a first signal collected by the first sensor in the first area includes the vehicle obtaining the audio signal collected by the first sensor, and controlling the vehicle to operate a first light emitting device based on the first signal includes the vehicle controlling the vehicle to operate the first light emitting device based on a first parameter of the audio signal.

[0271] In an embodiment of the present application, the vehicle can control the first light-emitting device to operate based on the parameters of the audio signal. In this way, the first light-emitting device can change with the parameters and create different atmospheres for the user, thereby helping to improve the user experience.

[0272] Optionally, the audio signal is music, and the first parameter comprises one or more of: a musical meter, a melody, lyric information, and color information of an album cover.

[0273] Optionally, the audio signal is music, and controlling by the vehicle to operate the first lighting device based on the first signal includes determining by the vehicle first information of the music based on a first parameter of the audio signal, wherein the first information includes one or more of a song title, a singer name, or a name of an album to which the music belongs, and controlling the first lighting device to operate in a second mode based on a mapping relationship between the first information and the operating mode of the lighting device.

[0274] In an embodiment of this application, the vehicle can determine the operation mode of the first light-emitting device based on the correspondence between the first information of music and the operation mode of the light-emitting device. In this way, the music and the operation mode of the light-emitting device preferred by the user can be combined, thereby helping to improve the user experience.

[0275] Optionally, before controlling the vehicle to operate the first lighting device, the method further includes the vehicle acquiring user information of a user located in the first area, and acquiring lighting configuration information corresponding to the user information based on the user information, and controlling the vehicle to operate the first lighting device includes controlling the vehicle to operate the first lighting device based on the lighting configuration information.

[0276] It should be understood that the lighting configuration information may be pre-configured in the vehicle before delivery or may be customized by the user. For example, the vehicle may receive configuration instructions from the user, and the configuration instructions may include a correspondence between different users and colors preferred by the users when communicating with the voice assistant. User A prefers blue ambient lighting when interacting with the voice assistant. User B prefers purple ambient lighting when interacting with the voice assistant.

[0277] Optionally, the sensor includes a temperature sensor, the first signal indicating a first temperature value, and controlling the vehicle to operate the first light-emitting device based on the first signal includes controlling the vehicle to operate the first light-emitting device when the first temperature value is higher than a preset temperature value or when the first temperature value is lower than a preset temperature value.

[0278] For example, as shown in (a) of FIG. 5, the multiple areas may be a driver's area, a front passenger area, a second-row left area, and a second-row right area. A temperature sensor located in the driver's area may collect a current temperature value (e.g., 25°C) of the driver's area. If the preset temperature value is 22°C, the vehicle may control the ambient lighting in the driver's area to operate in a first mode so that the user intuitively feels that the temperature of the driver's area is higher than the preset value. In this way, after feeling that the temperature of the driver's area is higher than the preset temperature value, the user can cool the temperature of the driver's area.

[0279] Optionally, the sensor includes a temperature sensor, the first signal indicating a first temperature value, and the vehicle controlling the first light-emitting device to operate based on the first signal includes the vehicle controlling the first light-emitting device to operate in a third operating mode when the first temperature value is higher than a preset temperature value, or the vehicle controlling the first light-emitting device to operate in a fourth operating mode when the first temperature value is lower than the preset temperature value, wherein the third operating mode and the fourth operating mode are different operating modes.

[0280] Optionally, controlling the vehicle to operate the first light-emitting device comprises controlling the first light-emitting device such that the vehicle displays a warm color tone when the first temperature value is higher than a preset temperature value, or controlling the first light-emitting device such that the vehicle displays a cool color tone when the first temperature value is lower than a preset temperature value.

[0281] For example, as shown in (a) of FIG. 5, when the temperature value detected by the temperature sensor in the driver's area is higher than a preset temperature value, the vehicle may control the ambient lighting in the driver's area to display warm colors so that the user can intuitively feel that the temperature in the driver's area is warming up.

[0282] Optionally, before controlling the vehicle to operate the first lighting device, the method further includes the vehicle acquiring user information of a user located in the first area and acquiring lighting configuration information corresponding to the user information based on the user information, and controlling the vehicle to operate the first lighting device includes controlling the vehicle to operate the first lighting device based on the lighting configuration information.

[0283] It should be understood that the lighting configuration information may be preset in the vehicle before delivery of the vehicle or may be customized by the user. For example, the vehicle may receive configuration instructions from the user, and the configuration instructions may include a correspondence between different users and colors preferred by the users when the first temperature is lower than a preset temperature value. User A prefers blue ambient lighting when the first temperature is lower than a preset temperature value. User B prefers purple ambient lighting when the first temperature is lower than a preset temperature value.

[0284] Optionally, the sensor includes a temperature sensor, and the first signal indicates a second temperature value, and before the vehicle controls the first light-emitting device to operate based on the first signal, the method further includes the vehicle detecting an action of a user located in the first area adjusting the temperature inside the vehicle to a third temperature value, and controlling the vehicle to operate the first light-emitting device based on the first signal includes controlling the vehicle to operate the first light-emitting device when the third temperature value is higher than the second temperature value or when the third temperature value is lower than the second temperature value.

[0285] For example, as shown in (b) of FIG. 5, a temperature sensor in the front passenger area detects that the current temperature in the front passenger area is 25° C., and the vehicle detects a user's action to adjust the temperature in the front passenger area to 28° C. In this case, the vehicle may control the ambient lighting in the front passenger area to operate in a second mode so that the user intuitively feels the user's intention to adjust the temperature, thereby realizing corresponding user visual feedback about the cooling / heating requirements and helping to improve the user experience.

[0286] Optionally, the sensor includes a temperature sensor, the first signal indicating a second temperature value, and before the vehicle controls the first light-emitting device to operate based on the first signal, the method further includes the vehicle detecting an action of a user located in the first area adjusting the temperature inside the vehicle to a third temperature value, and the vehicle controlling the first light-emitting device to operate based on the first signal includes the vehicle controlling the first light-emitting device to operate in a fifth operating mode when the third temperature value is higher than the second temperature value, or the vehicle controlling the first light-emitting device to operate in a sixth operating mode when the third temperature value is lower than the second temperature value, the fifth operating mode and the sixth operating mode being different operating modes.

[0287] Optionally, controlling the vehicle to operate the first interior light includes controlling the first light-emitting device such that the vehicle displays a warm color tone when the third temperature value is higher than the second temperature value, or controlling the first light-emitting device such that the vehicle displays a cool color tone when the third temperature value is lower than the second temperature value.

[0288] In an embodiment of the present application, when the third temperature value is higher than the second temperature value, the light-emitting device is controlled to display a warm color tone, so that the user can intuitively feel that the user's current intention is to warm up the temperature of the first area. When the third temperature value is lower than the second temperature value, the light-emitting device is controlled to display a cool color tone, so that the user can intuitively feel that the user's current intention is to cool down the temperature of the first area.

[0289] Optionally, the sensor includes a cup holder temperature sensor, and wherein the vehicle acquiring a first signal collected by the sensor in the first area includes the vehicle acquiring the first signal collected by the cup holder temperature sensor after detecting that a user has placed a cup in a cup holder located in the first area, the first signal indicating a fourth temperature value of the liquid in the cup, and the vehicle controlling the first light-emitting device to operate when the fourth temperature value is higher than a fifth temperature value or when the fourth temperature value is lower than a fifth temperature value, the fifth temperature being the temperature value of the liquid in the cup detected by the cup holder temperature sensor before the user placed the cup in the cup holder.

[0290] For example, as shown in FIG. 11 , the left cup holder includes a cup holder temperature sensor, and before a user places a cup in the cup holder, the temperature detected by the cup holder temperature sensor is 25° C. After the user places the cup in the cup holder, the temperature detected by the cup holder temperature sensor is 50° C. In this way, the vehicle can control the left cup holder ambient lighting to operate in a third mode so that the user intuitively feels that the temperature of the liquid in the cup is warming, thereby helping to improve the user experience.

[0291] Optionally, controlling the vehicle to operate the first interior light includes controlling the first light-emitting device such that the vehicle displays a warm color tone when the fourth temperature value is higher than the fifth temperature value, or controlling the first light-emitting device such that the vehicle displays a cool color tone when the fourth temperature value is lower than the fifth temperature value.

[0292] In an embodiment of this application, when the fourth temperature value is higher than the fifth temperature value, the first light-emitting device is controlled to display a warm color tone, so that the user can intuitively feel that the temperature inside the cup is higher than the temperature before the cup was placed, thereby avoiding burns caused by the user in the vehicle accidentally touching the cup.

[0293] Optionally, the method further includes, if the fourth temperature value is higher than the fifth temperature value, the vehicle controlling the first light-emitting device to change color from dark to light in a process in which the temperature detected by the cup holder temperature sensor cools from the fourth temperature to the fifth temperature, or, if the fourth temperature value is lower than the fifth temperature value, the vehicle controlling the first light-emitting device to change color from dark to light in a process in which the temperature detected by the cup holder temperature sensor warms from the fourth temperature to the fifth temperature.

[0294] In the embodiment of this application, in the process of a hot drink cooling to room temperature or a cold drink warming to room temperature, the color of the light-emitting device can change from dark to light and gradually return to the color corresponding to room temperature with the temperature change, which helps users intuitively feel the process of the temperature change of the liquid in the cup, thereby improving the user experience.

[0295] Optionally, the first room light is a cup holder ambient light.

[0296] Optionally, the first signal indicates position information of an object around the first vehicle door, and there is a correspondence between the first vehicle door and the first area, and the vehicle controlling the first light-emitting device to operate based on the first signal includes, when the vehicle is stationary and the object position information satisfies a preset condition, controlling the vehicle to operate the first light-emitting device in a seventh mode.

[0297] In an embodiment of this application, when the vehicle is stationary and there is an object passing outside the vehicle, the light-emitting device can notify the user that there is an object passing through the vehicle door, thereby preventing the user from colliding with the object after the vehicle door is opened.

[0298] Optionally, before the vehicle controls the first light-emitting device to operate in the seventh mode, the method further includes the vehicle detecting an action of a user located in the first area attempting to open the vehicle door.

[0299] Optionally, before the vehicle controls the first light emitting device to operate in the seventh mode, the method further comprises the vehicle detecting that the first area includes a user.

[0300] In an embodiment of the present application, before controlling the first light-emitting device to operate, the vehicle can first determine that a user is present in the first area. If a user is not present, the vehicle can control the first light-emitting device not to light up even if an object passes outside the vehicle, thereby helping to save power.

[0301] Optionally, the method further comprises, when controlling the first light emitting device to operate in the seventh mode, controlling the vehicle to lock the first vehicle door.

[0302] In an embodiment of this application, when there is an object passing through the vehicle door, the vehicle can further control the vehicle door to be locked, thereby avoiding a collision when the user is unable to react by using the light emitting device.

[0303] Optionally, the first lighting device includes a first interior light and a first exterior light, the seventh operating mode includes a first sub-mode and a second sub-mode, and controlling the first lighting device by the vehicle to operate in the seventh mode includes controlling the vehicle to control the first interior light to operate in the first sub-mode and to control the first exterior light to operate in the second sub-mode.

[0304] In an embodiment of this application, the first sub-mode may notify a user inside the vehicle that an object is passing outside the vehicle so that the user inside the vehicle can be warned. The second sub-mode may notify a user outside the vehicle that the vehicle door is about to open so that the user outside the vehicle can avoid it in a timely manner. In this way, occupants both inside and outside the vehicle are warned, thereby preventing the user from colliding with the object after the vehicle door is opened.

[0305] Optionally, before controlling the vehicle to operate the first lighting device, the method further includes the vehicle acquiring user information of a user located in the first area and acquiring lighting configuration information corresponding to the user information based on the user information, and controlling the vehicle to operate the first lighting device includes controlling the vehicle to operate the first lighting device based on the lighting configuration information.

[0306] It should be understood that the lighting configuration information may be preset in the vehicle before delivery or may be customized by the user. For example, the vehicle receives a setting instruction from a user. The setting instruction includes a correspondence between different users and pre-warning colors preferred by the users. User A's preferred pre-warning color is red, and user B's preferred pre-warning color is purple. In this case, when the vehicle detects that user A, who is located in a first area, is about to get out of the vehicle, if an object passes around, the lighting system may control a first light-emitting device in the first area to light up red, thereby achieving the effect of pre-warning for user A.
