It can control the matrix LED light source 2 and louvered grille 202 for precise local lighting based on the occupant's position and posture to avoid disturbing others. If the OMS camera 502 detects that an occupant is sleeping, it can automatically dim the lights, turn off the ventilation, or adjust the temperature, combined with the air quality inside the vehicle. A quality sensor automatically activates the ventilation fan 302. The controller 7 integrates data from the OMS camera 502, seat sensors, microphone, and ambient light, controlling the actuators of the matrix LED light source 2 and the ventilation fan 302 to achieve scene-based intelligent linkage. This enables more precise monitoring of occupant posture and position. When not in use, the sensor retracts and hides, enhancing physical privacy and preventing dust contamination. Combined with the encoder 105 and IMU module, it compensates for vehicle vibrations, maintaining the stability of the observed or projected beam, adaptively adjusting the brightness of different areas of the matrix LED light source 2, and controlling the matrix LED light source 2 and louvered grille 202 for precise localized lighting. To avoid disturbing others, the OMS camera 502 can detect if an occupant is asleep and automatically dim the lights, turn off the ventilation, or adjust the temperature. Combined with the in-vehicle air quality sensor, it can automatically start the ventilation fan 302. It also integrates a wirelessly connected alarm 101, which is linked with the controller 7. It also integrates the sunroof adjustment button 6 and the door control button 601. If the OMS camera 502 detects abnormalities, such as leaving a child behind or the driver being severely fatigued, it can trigger the alarm 101 to provide an audible and visual warning and remotely notify the owner via the wireless network. The physical button 4 is retained to control the sunroof and doors, providing a safe and redundant operation method in case the touch screen or voice may fail, which complies with the functional safety concept.
