[0053] In this embodiment, wheel speed information, gear information, rear motor wheel speed, front motor wheel speed, and left window information are obtained through the wire control brake system 21, the combination switch module 22, the rear motor control unit 23, the front motor control unit 24, and the left window air conditioner 25.
[0054] The right window information and air conditioning information are obtained through the right window controller 26 and the electric air outlet module 27.
[0055] Alternatively, if Figure 1 As shown, the abnormal driver behavior results obtained by the driver detection system 30 include fatigue driving behavior, distracted driving behavior and dangerous driving behavior. The driver detection system 30 includes a right domain controller 31, which is connected to the right window controller 26 and the electric air outlet module 27.

[0056] The left domain controller 32 is connected to the wire control brake system 21, the combination switch module 22, the rear motor control unit 23, the front motor control unit 24 and the left window controller. The left domain controller 32 is used to receive wheel speed information, gear information, rear motor wheel speed, front motor wheel speed and left window information, and simplify the electronic circuits of the wire control brake system 21, the combination switch module 22, the rear motor control unit 23, the front motor control unit 24 and the left window air conditioner 25; the left domain controller 32 is connected to the right domain controller 31, and the left domain controller 32 is used to receive the negative ion opening state feedback signal, the air conditioning wind speed feedback signal, and the air conditioning internal and external circulation mode switching feedback signal sent by the right domain controller 31.
[0057] In this embodiment, the left domain controller 32 cooperates with the right domain controller 31 to receive vehicle control information, and the circuits of various components in the vehicle control module 20 are simplified through the configuration of the left domain controller 32 and the right domain controller 31.
[0058] Alternatively, if Figure 1As shown, the feedback instructions generated by the driver detection system 30 include text reminder signals, distracted driving warning sound signals, camera obstruction or fault feedback signals, voice reminder signals, and volume adjustment signals. The motion instructions generated by the driver detection system 30 include negative ion opening request signals, air conditioning wind speed reduction request signals, window opening angle request signals, and air conditioning internal and external circulation mode switching request signals. The driver detection system 30 also includes a digital cockpit 33, which is connected to the driver monitoring camera 10. The digital cockpit 33 is used to receive and analyze the image information of the driver sent by the driver monitoring camera 10. The digital cockpit 33 is also connected to the left domain controller 32. The digital cockpit 33 is connected and receives the vehicle status information sent by the left domain controller 32.

The left domain controller 32 receives the feedback instruction and sends the feedback instruction to the right domain controller 31. The right domain controller 31 generates a window control signal and a wind speed adjustment signal according to the above signals. The right window controller 26 receives the window control signal, and the electric air outlet module 27 receives the wind speed adjustment signal.
[0059] Exemplarily, the driver detection system 30 further includes a digital cockpit 33, which is connected to the driver monitoring camera 10, and is used to receive and analyze the image information of the driver sent by the driver monitoring camera 10. The digital cockpit 33 is also connected to the left domain controller 32, and receives the negative ion opening state feedback signal, the air conditioning wind speed feedback signal, the air conditioning internal and external circulation mode switching feedback signal, the steering wheel angle signal, the actual gear position signal, and the vehicle speed signal sent by the left domain controller 32.
[0060] The digital cockpit 33 generates a text reminder signal, a distracted driving warning sound signal, a camera obstruction or fault feedback signal, a voice reminder signal, a volume adjustment signal, a negative ion turn-on request signal, an air conditioning wind speed reduction request signal, a window opening angle request signal, and an air conditioning internal and external circulation mode switching request signal based on the driver image information sent by the driver monitoring camera 10 and the negative ion turn-on status feedback signal, air conditioning wind speed feedback signal, air conditioning internal and external circulation mode switching feedback signal, steering wheel angle signal, actual gear position signal, and vehicle speed signal sent by the left domain controller 32.
[0061] The left domain controller 32 receives the negative ion turn-on request signal, the air conditioning wind speed reduction request signal, the window opening angle request signal, and the air conditioning internal and external circulation mode switching request signal, and sends the above signals to the right domain controller 31. The right domain controller 31 generates a window control signal and a wind speed adjustment signal according to the above signals. The right window controller 26 receives the window control signal, and the electric air outlet module 27 receives the wind speed adjustment signal.
[0062] Alternatively, if Figure 1 As shown, the driver interaction system 40 includes an instrument cluster 41, which is connected to the digital cockpit 33 and receives text reminder signals, distracted driving warning sound signals, and camera blocked or faulty feedback signals. The instrument cluster 41 provides text reminders based on the text reminder signals, distracted driving warning sound signals, and camera blocked or faulty feedback signals.
[0063] The audio power amplifier module 42 is connected to the digital cockpit 33 and receives a voice reminder signal and a volume adjustment signal.

[0065] Exemplarily, the instrument cluster 41 is connected to the digital cockpit 33, and receives text reminder signals, distracted driving warning sound signals, and camera blocked or faulty feedback signals. The instrument cluster 41 gives text reminders based on the text reminder signals, distracted driving warning sound signals, and camera blocked or faulty feedback signals.
[0066] The audio power amplifier module 42 is connected to the digital cockpit 33 to receive the voice reminder signal and the volume adjustment signal. The audio power amplifier module 42 generates the voice reminder instruction and the volume adjustment instruction according to the voice reminder signal and the volume adjustment signal.
[0067] The speaker 43 is connected to the audio power amplifier module 42 to receive the voice reminder instruction and the volume adjustment instruction. The speaker 43 plays the voice reminder and adjusts the volume according to the voice reminder instruction and the volume adjustment instruction.
[0068] Based on the same inventive concept, this embodiment also provides a control method for an intelligent driver behavior monitoring and safety reminder system, including the following steps.
[0069] Step 1: Acquire vehicle status information through the vehicle control module 20 and acquire driver image information through the driver monitoring camera 10.
[0070] Step two, the driver detection system 30 receives the vehicle status information sent by the vehicle control module 20 and the driver image information obtained by the driver monitoring camera 10. The driver detection system 30 determines whether to perform driver behavior monitoring and safety reminders based on the vehicle status information. If driver behavior monitoring and safety reminders are performed, the driver detection system 30 determines whether abnormal driver behavior occurs based on the vehicle status information and the driver image information.
[0071] Step three: if an abnormal driver action occurs, the driver detection system 30 activates the intelligent care mode through the abnormal driver action, and generates different feedback instructions and motion instructions according to different intelligent care modes.
[0072] In step 4, the driver interaction system 40 provides voice reminders and graphic reminders according to the different feedback instructions obtained in step 3, and the vehicle control module 20 adjusts the vehicle state according to the different motion instructions obtained in step 3, and reminds the driver to return to normal driving behavior by adjusting the vehicle state.
[0073] In this embodiment, the driver's abnormal driving actions are obtained by real-time monitoring of the driver's behavior, and multi-level safety reminders are provided according to the driver's different abnormal driving actions, thereby effectively improving driving safety.
[0074] Alternatively, if Figure 2 As shown, the abnormal driver actions obtained in step 2 include fatigue driving behavior, distracted driving behavior and dangerous driving behavior. If the intelligent care for fatigue driving behavior is turned on, a voice reminder about fatigue driving is played through the speaker 43, a graphic reminder about fatigue driving is played through the combination instrument 41, the window is controlled to be lowered through the left window controller and the right window controller 26, and the air conditioner is controlled to be turned on through the electric air outlet module 27, so as to remind the driver to return to normal driving behavior.
[0075] For example, when the camera detects that the driver is fatigued, the system combines with the vehicle control module 20 to obtain the current driving time for judgment, and divides fatigue driving into two levels: severe and mild, with different levels of prompts. When mild fatigue driving behavior (yawning multiple times in a short period of time, closing eyes, etc.) is detected, a voice reminder "You are mildly fatigued" is given through the speaker 43, and a text prompt is displayed on the instrument cluster 41 for 10 seconds; if the driver continues the above fatigue driving behavior, the reminder will continue at intervals of 3 seconds until the action stops. If the action continues during this period, there will be no response.
[0076] When severe fatigue driving behavior is detected (closing eyes for more than 2 seconds), the speaker 43 reminds you that you are severely fatigued, and the text prompt of the instrument cluster 41 lasts for 10 seconds.
[0077] If the driver continues to drive while fatigued, the system will continue to remind the driver every 3 seconds until the action stops. If the driver continues to drive while fatigued, there will be no response.
[0078] When both mild fatigue driving behavior and severe fatigue driving behavior exist, the system sends a signal state of severe fatigue driving level value and executes the action of severe fatigue driving behavior.
[0079] The condition for not enabling the intelligent care function for fatigue driving behavior is that the vehicle power gear is switched to the off state.
[0080] The information obtained through the camera and the vehicle control module 20 is used to distinguish the degree of fatigue driving, and then the corresponding vehicle reminder action is executed according to the driver's fatigue level. In this way, multi-level safety reminders about fatigue driving are provided to further improve driving safety.
[0081] Alternatively, if Figure 2 As shown, if the intelligent care for distracted driving behavior is turned on, a voice reminder about distracted driving is played through the speaker 43, a graphic reminder about distracted driving is played through the instrument cluster 41, the window is controlled to be lowered through the left window controller and the right window controller 26, the air conditioner is controlled to be turned on through the electric air outlet module 27, and the volume of the voice reminder, the conspicuousness of the graphic reminder, and the size of the window opening are adjusted to remind the driver to return to normal driving behavior.
[0082] For example, during driving, any behavior that is not focused on driving is called distracted behavior (such as looking down to find something, looking around, etc.). If the system detects the above behavior for 3 seconds, it will give a voice reminder through the speaker 43: Please concentrate and drive carefully. At the same time, the text prompt and warning sound reminder (default) on the instrument cluster 41 will last for 10 seconds. The air conditioner is turned on through the electric air outlet module 27, and the window is lowered through the left window controller and the right window controller 26, so as to further remind the driver to return to normal driving behavior through the opening and closing of the air conditioner and the window.
[0083] If the driver continues to be distracted, the system will continue to remind the driver at intervals of 3 seconds until the behavior stops. If the driver continues to be distracted during this period, there will be no response.
[0084] The driver's actions are observed by the driver monitoring camera 10 to reduce false alarms. For example, observing the driver checking the exterior rearview mirrors or the blind spot behind the vehicle is not considered as distraction.
[0085] Because when attention and fatigue monitoring work together, when distraction and fatigue occur at the same time, the distraction alarm will be given priority.
[0086] The condition for not activating the distracted driving intelligent care function is that the vehicle power gear is switched to the off state.
[0087] Compared with fatigue driving, distracted driving is more likely to be dangerous. Therefore, adding safety reminders can further improve driving safety.
[0088] Alternatively, if Figure 2 As shown, if the intelligent care for dangerous driving behavior is turned on, a voice reminder about dangerous driving behavior is played through the speaker 43, a graphic reminder about dangerous driving behavior is played through the instrument cluster 41, the window is controlled to be lowered through the left window controller and the right window controller 26, the air conditioner is controlled to be turned on through the electric air outlet module 27, and the volume of the voice reminder, the conspicuousness of the graphic reminder, the size of the window opening, and the air inlet and outlet of the car air conditioner are adjusted to remind the driver to return to normal driving behavior.
[0089] Intelligent Care: When the camera detects dangerous driving behavior (smoking, drinking, making phone calls, etc.) for 3 seconds, a voice reminder will be given on the instrument cluster 41 and the speaker 43: Pay attention to driving safety. The text reminder on the instrument cluster 41 will last for 10 seconds. If the user continues the dangerous driving behavior, the reminder will continue at intervals of 3 seconds until the action stops. If the action continues during this period, there will be no response.
[0090] When the driver's smoking behavior is detected, no dangerous driving reminder is given, and intelligent care for dangerous driving behavior is activated according to the conditions, the electric air outlet module 27 is turned on, negative ion purification is turned on, internal and external circulation is switched, the left window controller 25 and the right window controller 26 are turned on, and the window is opened at a 30° angle;
[0091] When it detects that the driver is making a phone call, the system will not issue a dangerous driving reminder, but will actively lower the media playback volume and the air conditioning wind speed (by 10%). After the call, the media playback volume will be restored. When the mobile phone Bluetooth is connected to the car's large-screen Bluetooth, the incoming call will actively lower the volume and air conditioning wind speed and prioritize the Bluetooth strategy, and the driver monitoring camera will not perform repeated operations.
[0092] The condition for not enabling the intelligent care function for dangerous action behaviors is that the vehicle power gear is switched to the off state.
[0093] The information obtained through the camera and the vehicle control module 20 is used to distinguish dangerous actions, and then corresponding vehicle reminder actions are performed according to the driver's dangerous actions. In this way, multi-level safety reminders about fatigue driving are provided to further improve driving safety.
[0094] The above is an exemplary description of the present invention in combination 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 such non-substantial improvements are made by adopting 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.
