Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically, to a driver fatigue warning system and vehicle based on basic vehicle configuration. Background Technology

[0002] High-end vehicles on the market are typically equipped with advanced fatigue monitoring systems. These systems use cameras and other devices to capture the driver's facial features, eye movements such as blinking frequency and eye closure time, and head movements. After prolonged driving, if the driver's blinking frequency slows down or eye closure time lengthens, the system analyzes this data to determine the level of fatigue. The ECU algorithm then automatically assesses the driver's fatigue state and provides alerts via steering wheel vibration, seat vibration, and other methods.

[0003] However, for lower-spec vehicles, the lack of these advanced features means that drivers cannot receive effective warnings when they are fatigued, thus increasing the risk of traffic accidents. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Combined with appendix Figure 1-3 As shown, a driver fatigue reminder system based on vehicle basic configuration includes: a fatigue reminder switch 200, a voice command recognition module 300, a thermal management control system 400, an audio reminder system 500, and a window control system 600, all connected to a vehicle body domain controller 100. The fatigue reminder switch and the voice command recognition module are used to collect driver fatigue status information issued by pressing or speaking, respectively. The system controls the airflow size and temperature of the thermal management control system, and / or the music, sound effects, or volume of the audio reminder system, and / or the window opening of the window control system through the vehicle body domain controller.

[0026] In one optional embodiment, the vehicle domain controller is also hardwired to a hazard warning light to alert the driver and other vehicles to avoid the vehicle by flashing the hazard warning light.

[0027] In one specific embodiment

[0028] The vehicle body domain controller 100 is used to receive trigger signals from the fatigue reminder switch and the voice command recognition module, as well as signals from the rain and light sensor. Based on these signals, it drives the operation of the windows and hazard lights, controls the air conditioning system to turn on, and sends fatigue reminder requests to the cabin domain controller.

[0029] Fatigue alert switch 200: Installed in a location inside the vehicle that is easily accessible to the driver, such as the side of the center console or the steering wheel; connected to the vehicle body control via a hard wire; used for manual operation by the driver when feeling fatigued or drowsy to trigger the fatigue alert function.

[0030] Voice command recognition module 300: Integrated into the vehicle audio or infotainment system, including a microphone that is hardwired to the cockpit domain controller, used to recognize the driver's voice commands, such as "I need to stay awake" or "Turn on fatigue reminder", thereby triggering the fatigue reminder function.

[0031] The thermal management control system 400 includes a thermal management controller and a condenser, evaporator, and expansion valve connected to the thermal management controller via hard wiring. It may also include electrically operated air vents connected to the body domain controller via a LIN bus. Upon receiving a fatigue alert request signal from the body domain controller's CAN bus, the thermal management controller adjusts to a preset face-blowing mode at maximum power and blows air at a preset temperature. When the fatigue alert switch is pressed or a voice command is recognized by the voice command recognition module, the thermal management control system immediately adjusts the thermal management controller to the preset face-blowing mode at maximum power. If the vehicle is equipped with electrically operated air vents, the thermal management control system will automatically adjust the vent angle via the body domain controller; if the vehicle does not have electrically operated air vents, the driver must manually set them in advance. The air temperature can be preset to cold or hot air via the vehicle's infotainment system according to the season or the driver's personal preference for a quick refreshing effect.

[0032] Audio alert system 500: Consists of an in-vehicle entertainment system with speakers or a dedicated audio alert module, with the speakers connected to the cockpit domain controller via hardwire. When the fatigue alert function is triggered, the audio alert system plays preset, energetic music, sound effects, or specific alarm sounds through the speakers. The volume is carefully tuned to be moderate, effectively waking the driver's attention without interfering with normal driving operations.

[0033] The window control system 600 includes windows connected to the body controller via hardwire and a rain sensor connected to the body controller via a LIN bus. The rain sensor monitors ambient light intensity and rain conditions, sending signals to the body domain controller via the LIN bus. The window control system, in conjunction with the rain sensor, determines whether it is raining. If the determination is that it is not raining and the windows are closed, the window control system simultaneously opens the windows to a suitable position, typically lowering them by 1 / 3 to 1 / 2 of their height, to increase airflow and further refresh the mind.

[0034] A customizable settings module, located within the cockpit domain controller or central control screen, allows vehicle owners to customize the specific reminder content and effects triggered by a "one-click wake-up" function or voice command via the vehicle's infotainment system. This includes, but is not limited to, music selection, sound effect type, alarm sounds, air conditioning temperature, and whether windows are open, catering to the individual needs of different users. In this embodiment, the central control screen is connected to the cockpit domain controller. The central control screen recognizes the driver's voice commands and sends the command signals to the cockpit domain controller via the CAN bus. It also receives fatigue reminder requests from the body domain controller via the CAN bus, controls the audio reminder system to play preset reminder content, and provides a customizable settings interface (central control screen) for the vehicle owner to set the specific content and effects of the fatigue reminder.

[0035] Furthermore, the cockpit domain controller is connected to the CAN_H line and CAN_L line, which are connected to the body domain controller. The CAN_H line and CAN_L line are also connected to the electric compressor and the thermal management controller, respectively, so that the electric compressor and the thermal management controller can be controlled through the body domain controller.

[0036] The fatigue alert system works as follows:

[0037] (1) Triggering phase

[0038] When a driver feels fatigued or drowsy, they can choose to manually operate the fatigue reminder switch or trigger the system function via voice command. After the fatigue reminder switch is pressed or the voice command is recognized by the voice command recognition module, the corresponding trigger signal will be sent to the vehicle domain controller.

[0039] (2) Control and processing stage

[0040] After receiving the fatigue warning trigger signal, the vehicle domain controller first determines whether the vehicle is equipped with electric air vents, and then combines this information with a rain / light sensor signal to determine whether it is raining, making a comprehensive judgment and processing accordingly. Specifically:

[0041] If the system determines that the vehicle has electric air vents, it will immediately adjust the air conditioning vent mode to face-blowing mode and send a request to the thermal management controller to blow air at the preset temperature at maximum power.

[0042] If the vehicle domain controller determines that it is not raining and the windows are closed, it will immediately drive the windows to the appropriate position and turn on the hazard warning lights.

[0043] At the same time, the body domain controller sends a fatigue alert request to the cockpit domain controller.

[0044] (3) Reminder Stage

[0045] When the cockpit domain controller receives a fatigue alert request, it immediately drives the speaker to play the preset alert content.

[0046] (4) Additional functions

[0047] Car owners can customize the reminder content and effects through the vehicle's infotainment system according to their personal preferences, including but not limited to music selection, sound effect type, alarm sound, air conditioning temperature, and whether to open windows. The infotainment system stores the owner's customized settings in the corresponding storage chip and sends the settings to the body domain controller and cockpit domain controller when the system is triggered, so as to realize personalized fatigue reminders.

[0048] In this embodiment of the fatigue reminder system, when the driver operates the fatigue reminder switch or triggers the reminder function through a voice command, the vehicle domain controller automatically opens the windows and hazard warning lights, the air conditioning system turns on according to a preset mode, and the audio reminder system plays a voice reminder or music that can keep the driver awake according to a preset setting.

[0049] The fatigue alert system supports both manual operation and voice command triggering, making it convenient for drivers to use in various situations. Simultaneously, through a combination of methods such as air conditioning blowing on the face, playing reminder audio, and opening windows for ventilation, it can more effectively refresh the driver's mind, improve driver attention, and thus reduce the risk of traffic accidents caused by fatigued driving. Furthermore, the customizable settings function meets the personalized needs of different users, enhancing the user experience.

[0050] Example 2:

[0051] See attached document Figure 2-3 A vehicle is equipped with a driver fatigue warning system based on the vehicle's basic configuration as described in Embodiment 1, comprising: a body domain controller, and fatigue warning switches, windows and hazard warning lights connected to the body controller via hard wiring, an electric air vent and a rain sensor connected via a LIN bus, and a cockpit domain controller, an electric compressor and a thermal management controller connected via CAN_H and CAN_L lines.

[0052] Furthermore, the cockpit domain controller is also connected to a microphone, speaker, and central control screen; the thermal management controller is connected to the condenser, evaporator, and expansion valve via hardwired connections.

[0053] The fatigue reminder switch allows drivers to manually trigger the fatigue reminder function.

[0054] The rain light sensor is used to monitor ambient light intensity and whether it is raining, and sends the signal to the vehicle domain controller via the LIN bus.

[0055] The cockpit domain controller is used to issue control commands to make the speakers play preset energetic music, sound effects, or specific alarm sounds; it also recognizes voice commands received through the microphone and sends the command signals to the body domain controller via the CAN bus; it also works with the central control screen to receive fatigue reminder requests sent by the body domain controller via the CAN bus, controls the speakers of the audio reminder system to play preset reminder content, and provides the owner with a customizable settings interface through the central control screen, allowing the owner to set the specific content and effects of the fatigue reminder.

[0056] The vehicle body domain controller receives trigger signals from the fatigue warning switch and voice command recognition module, as well as signals from the rain and light sensor. Based on these signals, it drives the operation of the windows and hazard lights, controls the air conditioning system to turn on, and sends fatigue warning requests to the cabin domain controller.

[0057] The thermal management controller, upon receiving a fatigue alert request signal from the CAN bus of the vehicle body domain controller, adjusts to the preset face-blowing mode at maximum power and blows out air at the preset temperature.

[0058] Although the present invention has been described herein with reference to illustrative embodiments, the above embodiments are merely preferred embodiments of the present invention, and the implementation of the present invention is not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
