[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0038] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0039] like Figure 1 As shown, an embodiment of the present invention provides a method for controlling a vehicle cabin atmosphere light, the method comprising the following steps:

[0040] S100, detecting the travel state, when the travel state is the start travel state, the ambient lights of all areas are turned on, and the ambient lights are made to perform a welcoming dynamic effect;

[0041] S200, when the travel state is a steady travel state, determining cabin occupancy information, and determining a turn-on area of ​​the ambient light according to the cabin occupancy information;

[0042] S300, collecting a facial image of the driver, determining the driver information and the driver status according to the facial image of the driver, and determining the color and brightness of the ambient light according to the driver information and the driver status;

[0043] S400, monitoring navigation information, and determining a lighting dynamic effect according to the navigation information, so that the ambient light in the front area performs the lighting dynamic effect;

[0044] S500, when the travel status is the end of travel status, the ambient lights of all areas are turned on, and the ambient lights are made to perform a dynamic effect of seeing off guests.

[0045] It should be noted that the cabin atmosphere light can not only provide basic lighting functions, but also create a diverse cabin atmosphere through different colors, brightness and dynamic effects, and enhance the riding experience of drivers and passengers. However, most of the existing vehicle cabin atmosphere light control methods adopt simple switch control or preset static color mode, lacking intelligent linkage with the vehicle driving state, cabin riding conditions and driver's personal characteristics. This results in the relatively single function of the atmosphere light, which cannot be flexibly adjusted according to actual needs, thereby limiting its potential in improving the riding experience. For example, when the vehicle starts to travel, the existing atmosphere light often simply turns on or maintains a fixed color, lacks the dynamic effect of welcoming guests, and cannot bring a novel and pleasant starting experience to the driver and passengers. Similarly, during the steady driving of the vehicle, the control of the atmosphere light also lacks intelligent association with the cabin riding information and the driver's state, and cannot adjust the light area, color and brightness according to the actual situation to adapt to different riding needs and driving conditions. In addition, during the navigation process, the atmosphere light also fails to make full use of the navigation information to provide dynamic effects to enhance the driver's driving experience. The embodiments of the present invention are intended to solve the above problems.

[0046] In the embodiment of the present invention, the travel status is automatically detected. When the travel status is the starting travel status, the atmosphere lights of all areas are turned on, and the atmosphere lights are made to perform a welcoming dynamic effect, providing a novel and pleasant starting experience for the driver and passengers. The welcoming dynamic effect is set in advance, and multiple welcoming dynamic effects can be set for users to choose. When the travel status is a steady travel status, the cabin riding information is determined, and the opening area of ​​the atmosphere lights is determined according to the cabin riding information. The atmosphere lights are only turned on in the area where passengers are riding, which not only ensures the lighting effect but also saves electricity. At this time, the driver's facial image is also collected, and the driver's information and driver's status are determined according to the driver's facial image. The color of the atmosphere lights and the color brightness of the atmosphere lights are determined according to the driver's information and driver's status to adapt to different riding needs and driving states, and increase the functionality of the atmosphere lights. In addition, the embodiment of the present invention also monitors the navigation information, determines the lighting dynamic effect according to the navigation information, and makes the atmosphere lights in the front area perform the lighting dynamic effect to enhance the driver's driving experience. Finally, when the travel status is the end of the travel status, the ambient lights in all areas are turned on, and the ambient lights perform a dynamic effect of seeing off guests, providing a warm ending experience for the driver and passengers.

[0047] like Figure 2 As shown, as a preferred embodiment of the present invention, the step of determining the cabin occupancy information and determining the activation area of ​​the atmosphere light according to the cabin occupancy information specifically includes:

[0048] S201, determining whether each seat in the vehicle cabin is occupied by a passenger based on a pressure sensor, and obtaining cabin occupancy information, wherein the cabin occupancy information includes seat numbers of occupied seats;

[0049] S202: Determine a corresponding cockpit area according to the seat number, where the cockpit area is a turned-on area for the ambient light.

[0050] In an embodiment of the present invention, in order to determine the cabin occupancy information, a pressure sensor is installed on each seat, so that it is possible to determine whether each seat in the vehicle cabin is occupied by a passenger based on the monitoring data of the pressure sensor, and obtain the cabin occupancy information. The cabin occupancy information includes the seat numbers of the passengers, and then the corresponding cabin areas are determined based on the seat numbers. The cabin areas are the areas where the atmosphere lights are turned on. For example, if only the driver and co-driver seats are occupied, only the front row atmosphere lights will be turned on, and the rear row atmosphere lights will not be turned on.

[0051] like Figure 3 As shown, as a preferred embodiment of the present invention, the step of determining the driver information and the driver status according to the driver's facial image specifically includes:

[0052] S301, matching the driver's facial image with the head portrait in the portrait library to determine the driver's information;

[0053] S302, preprocessing and feature extraction of the driver's facial image to obtain eye features, mouth corner features and eyebrow features;

[0054] S303, determining whether the driver is in a fatigue state according to the blinking frequency and eyelid closure degree in the eye characteristics;

[0055] S304, judging whether the driver is in a depressed state according to whether the mouth corner features and eyebrow features meet the condition of drooping mouth corners and furrowed eyebrows;

[0056] S305, when the driver is not in a fatigue state and a depressed state, it is determined that the driver is in a normal state.

[0057] In the embodiment of the present invention, in order to determine the driver information and the driver state, the driver's facial image is first matched with the head portrait in the portrait library to determine the driver information. If the match is not successful, the driver information is other, and the portrait library needs to be constructed by the user. Then the driver's facial image is preprocessed and feature extracted. The preprocessing is to denoise, grayscale, and histogram equalization of the collected facial image to improve the image quality. After feature extraction, eye features, mouth corner features, and eyebrow features will be obtained. Then, according to the blinking frequency and eyelid closure degree in the eye features, it is determined whether the driver is in a fatigue state. The blinking frequency is reduced and the eyelid closure degree is large, indicating that the driver is in a fatigue state; and according to whether the mouth corner features and eyebrow features meet the drooping mouth corners and frowning eyebrows, it is determined whether the driver is in a depressed state. When the driver is not in a fatigue state or a depressed state, it is determined that the driver is in a normal state.

[0058] like Figure 4 As shown, as a preferred embodiment of the present invention, the step of determining the color of the ambient light and the color brightness of the ambient light according to the driver information and the driver status specifically includes:

[0059] S306, when the driver is in a fatigue state, retrieve the ambient light color and ambient light color brightness corresponding to the fatigue state;

[0060] S307, when the driver is in a depressed state, retrieve the ambient light color and ambient light color brightness corresponding to the depressed state;

[0061] S308, when the driver status is normal, retrieve the ambient light color and ambient light color brightness corresponding to the driver information.

[0062] In the embodiment of the present invention, when the driver is in a fatigue state, the color and brightness of the ambient light corresponding to the fatigue state are retrieved. At this time, the color and brightness of the ambient light are brighter, and the color of the ambient light is white or orange. The color temperature of white light is usually above 5000K, which belongs to a cold color and has a high brightness, close to the sunlight at noon. This light is conducive to improving attention and concentration. Orange light may most easily cause insomnia, and orange light will make brain activity more intense. When the driver is in a depressed state, the color and brightness of the ambient light corresponding to the depressed state are retrieved. At this time, the color and brightness of the ambient light are normal, neither too bright nor too dark. The color of the ambient light is warm-toned light, such as yellow, orange and red, which usually gives people a feeling of warmth, comfort and relaxation. These colors can stimulate the pleasure center in the brain and help improve mood. In particular, yellow light has a calming effect, can help relax the body and mind, relieve tension and pressure, and can be used to assist in the treatment of psychological tension and anxiety caused by excessive work or academic pressure. Pink light has a certain effect on emotional soothing and relaxation. The pink light is transmitted to the cerebral cortex through the human eyes, and then to the hypothalamus, through the pineal gland and pituitary gland, stimulating the adrenal glands, causing the adrenal medulla to secrete less adrenaline, so that the human physiology can relax, the heart activity gradually slows down, and the muscles are also relaxed, so that the human mood is relieved and relaxed. When the driver's state is normal, the ambient light color and ambient light color brightness corresponding to the driver information are retrieved. Each driver information has its own ambient light color and ambient light color brightness set in advance according to preference.

[0063] like Figure 5 As shown, as a preferred embodiment of the present invention, the step of determining the dynamic lighting effect according to the navigation information specifically includes:

[0064] S401, when the navigation information indicates that a turn is required, the ambient light on the corresponding side is made to display a turning dynamic effect according to the turning direction;

[0065] S402, when the navigation information indicates speeding, the front row ambient light displays a speeding dynamic effect;

[0066] S403, when the navigation information shows a dangerous road section, the ambient light in the front row is used to display a warning dynamic effect.

[0067] In the embodiment of the present invention, the navigation information is also monitored in real time. When the navigation information shows that a turn is required, the atmosphere light on the corresponding side is displayed according to the turn direction. For example, when turning left, the atmosphere light on the main driver's side is displayed with a turn dynamic effect, and when turning right, the atmosphere light on the co-driver's side is displayed with a turn dynamic effect. The turn dynamic effect is set in advance. When the navigation information shows speeding, the atmosphere light in the front row is displayed with a speeding dynamic effect. When the navigation information shows a dangerous road section, such as a school area or an accident-prone area, the atmosphere light in the front row is displayed with a warning dynamic effect. The speeding dynamic effect and the warning dynamic effect are also set in advance.

[0068] As a preferred embodiment of the present invention, the starting travel state refers to the state within a set time period (for example, five minutes) after the vehicle is started, the steady travel state refers to the state after the vehicle is started after a set time period, and the ending travel state refers to the state within a set time period after the vehicle is shut down.

[0069] As a preferred embodiment of the present invention, the method further includes: when the user selects the energy-saving mode, the ambient lights of all areas are turned off; when it is detected that the battery power is lower than a power threshold (for example, 10%), the energy-saving mode is automatically entered.

[0070] An embodiment of the present invention further provides a vehicle, the vehicle comprising an atmosphere light and a controller, the controller being connected to the atmosphere light, and the controller being used to execute the steps in the control method of the vehicle cabin atmosphere light.
