[0014] The following is a brief description of the contents of each figure in the utility model specification:
[0015] Figure 1 This is the principle block diagram of the car interior atmosphere light control system. DETAILED DESCRIPTION
[0016] The following is a further detailed description of the specific implementation methods of the present invention, such as the shapes and structures of the components involved, the relative positions and connection relationships between the components, the functions and working principles of the components, the manufacturing process and the operation and use methods, etc., through the description of the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.
[0017] The automotive interior ambient light control system is mainly composed of ambient light fixtures and ambient light controllers. The ambient light fixtures are actuators, and the ambient light controllers are used to control the operation of the ambient light fixtures. The ambient light fixtures are composed of multi-color, brightness-adjustable light strips, and the light strips are composed of lamp beads arranged in sequence. Each lamp bead can be independently controlled and circuited, which can realize complex control methods of the controller and improve the system's interactive capabilities. The lamp beads are LEDs that can individually adjust RGB and brightness.
[0018] The ambient light controller includes an MCU, a power supply circuit and a vehicle network transceiver. The MCU communication port is connected to the vehicle network transceiver. The MCU accesses the vehicle communication network through the vehicle network transceiver to obtain the vehicle working condition information. The vehicle network includes a LIN transceiver and a CAN transceiver, that is, the MCU accesses the vehicle CAN network and the LIN network through the vehicle network transceiver. The ambient light controller is provided with a power supply circuit, which independently supplies power to the entire system. The input end of the power supply circuit is connected to the vehicle battery, and the output end of the power supply circuit is connected to the power end of the MCU. The MCU is connected to the central control screen through the vehicle network, and the central control screen can be used to complete the interaction with the user, which is convenient for inputting the desired control method.
[0019] In the automotive ambient light control system, the MCU receives instructions from other vehicle systems through the CAN transceiver, obtains the status data of each vehicle sensor, and sends the ambient light controller's own status to tell other controllers the current working condition of the ambient light controller. The MCU processes the input information to execute different working conditions. Specifically, the ambient light controller, as the core of the network, converts this information into CAN information frames or LIN information frames and sends them to each lamp through the CAN or LIN bus. In addition, this method can realize the individual control of a single lamp bead and the adjustment of the RGB and brightness of a single LED.
[0020] Through the CAN bus, the ambient light controller can obtain data from various sensors on the vehicle body, as well as the vehicle computer and some switch signals from the domain controller. As the input source in the control system, the ambient light controller reads and analyzes the data to switch between various working conditions and adjust the color and brightness of the ambient light to adapt to different environments and needs.
[0021] The operating condition information obtained by the MCU through the vehicle network includes: light intensity; rainfall information; vehicle ignition status; driving mode; audio rhythm information; and air conditioning status information. The specific use of the operating condition information can be designed according to the vehicle. This application only protects the overall system hardware construction, but provides feasible implementation examples for specific control methods.
[0022] When it is turned on and off, and the large screen is set to pure color mode, the controller can read the received RGB data and drive the lamps to display the corresponding RGB lighting effects.
[0023] Symphony display mode: When the ambient light controller reads that the vehicle power gear is in ignition state and the ambient light switch is on, and when it reads that the large screen is set to the symphony display mode, it drives the lamps to achieve different gradient effects by reading the values corresponding to the 7 symphony gradient colors.
[0024] Driving mode: When the ambient light controller reads that the vehicle's power gear is in ignition status and the ambient light switch is on, when the driving mode is switched to sports mode, it automatically switches to the red theme gradient color lighting effect of the fantasy display to match the driving style. When it is switched to comfort mode, it automatically switches to the green theme gradient color lighting effect of the fantasy display to match the driving style.
[0025] Music rhythm mode: When the ambient light controller reads that the vehicle power gear is in ignition state, and the ambient light switch is turned on, the music rhythm switch is turned on at the same time. The music rhythm color effect is determined according to the selected pure color mode or fantasy color display mode. By analyzing the music amplitude signal, the lamp beads are controlled to move rhythmically according to the high and low frequencies of the music.
[0026] Air conditioning linkage mode: When the ambient light controller reads that the vehicle power gear is in the ignition state, and the ambient light switch is turned on, and the air conditioning linkage switch is turned on, when the air conditioning temperature signal rises, the driving lamps flow from bottom to top with a red theme gradient color. When the air conditioning temperature signal drops, the driving lamps flow from top to bottom with a blue theme gradient color.
[0027] Brightness adjustment: The brightness display of all ambient light functions is uniformly controlled through brightness signals.
[0028] Manual adjustment: When the ambient light controller reads that the adaptive brightness switch is turned off, it can adjust the global brightness of the ambient light by reading the large-screen light brightness signal.
[0029] Automatic adjustment: When the ambient light controller reads that the adaptive brightness switch is turned on, it reads the light brightness inside and outside the car through the light and rain sensor on the car body, and automatically adjusts the large screen light brightness signal to adjust the global brightness of the ambient light. At this time, if it reads that the adaptive brightness switch is off, it automatically switches back to manual adjustment mode. When the user manually adjusts the large screen light brightness signal, the brightness will not be automatically adjusted during this ignition cycle and will return to manual adjustment mode.
[0030] The utility model of the atmosphere light controller can make the atmosphere light achieve different effects in different working scenes, improve the grade of the interior, especially at night, it can make the space inside the car more visually attractive. The atmosphere light controller allows you to design the lighting effect according to your needs, improve the driving experience according to the driving scene, and make the atmosphere light appear more modern. Through adaptive lighting, you can get different brightness experiences at night and during the day, without manual operation, let intelligence change the car.
[0031] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
