After the cloud servo module 30 responds, it can further implement the takeover and drive, thereby achieving the effect of relieving the driver's fatigue driving.

The present invention also provides a fatigue driving control method, as shown in FIG. 3, comprising: Step S10: acquiring a physiological parameter of a driver through a physiological parameter sensing module; Step S20: using the vehicle processing module to drive the driver The physiological parameter is transmitted to a cloud server module; and step S30: determining, by the cloud server module, whether the driver is fatigued to drive according to the physiological parameter of the driver, and if so, the vehicle processing module adopts a safety control measure.

In the above method, the safety control measure is to remind the driver to drive fatigue, and when the driver does not respond to the fatigue driving reminder, the safety control measure becomes to control the vehicle to slow down or stop to achieve hierarchical regulation. In the fatigue driving control method of the present invention, the driver can also actively initiate a fatigue driving control request to the in-vehicle processing module.

Specifically, the software flow for explaining the function of preventing driver fatigue driving is as shown in FIG. 4:

1. Starting the magnetic field electrode sensor built in the driving cushion and the infrared thermal stack sensor to the driver's seat, the driving cushion can be tied to the back of the chair by the strap rope, and the grounding pad of the conductive cloth is built. Placed horizontally on the seat, the driver's pad is cabled to the T-BOX on the seat base, and the power is supplied from the T-BOX.

2. The driving cushion contains the MCU, and the T-box communicates with the UART serial port. The physiological parameters of the driver's body ECG and body temperature changes will be collected at any time and transmitted to the T-box. The data can exist in the internal memory of the T-BOX. In the body or in the TF card, the 4G/3G/2G modem registered on the Internet can be sent to the cloud server module 30 of the TSP (telematics service provider). The cloud servo module 30 can back up and store the driver's normal ECG data, body temperature data, normal driving behavior habits, and collect data from the acceleration sensor and gyroscope from the T-box, and then evaluate the driving habits by software algorithms. If you like to go straight or snake, and so on.

3. When the driver is sickly driving or drunk driving, the cushion automatically sends the physiological value of the driver's body ECG parameter, and the physiological data of the body temperature parameter change value to the cloud servo module 30 via the T-box, which will perform the query database. The driver's normal physiological parameters are compared, and the driver's physical fatigue or abnormality level is judged by the software algorithm. Once the warning value is reached, the cloud servo module 30 implements a safety control measure to the driver's mobile phone terminal and T- The box sends out an alarm signal to inform the user that he is in fatigue driving. It is recommended to find a driver based on the fatigue level. If necessary, call back the cloud customer service phone to request the driver service; if the user ignores the alarm and does not respond, The T-box automatically issues an alarm voice prompt. If the user does not decelerate after the voice prompt, the speed detects the acceleration sensor data from the T-box, and does not stop driving, but also performs abnormal driving. The cloud servo module 30 issues an automatic control command to the T-BOX. The first deceleration command is transmitted to the transmission control module externally attached to the CAN bus through the CAN bus of the T-box, forcing the vehicle to decelerate; When the servo module 30 determines that the driver is in severe fatigue driving, the driver sends a stop command to the engine control module that is externally attached to the CAN busbar through the CAN busbar of the T-box, and controls the vehicle brake device to forcibly stop. Others can know the location of the parked vehicle at any time through GPS positioning. In answering the call, the cloud customer service staff will call the T-box to talk to the driver of the vehicle. The driver hears the Speaker customer service voice in the T-BOX, and can answer the communication by pressing the hands-free button.

The discomfort not only collects the driver's heart rate changes, but also collects body temperature changes, which helps to analyze the driver's physiological condition in real time.

The driving cushion directly communicates with the Telematics-Box through the serial port, which not only collects the driver's ECG parameters, but also the body temperature parameters, and can be uploaded to the cloud servo module 30 through the built-in 2G/3G/4G module for real-time analysis and processing.

The fatigue driving control method of the invention not only has the non-contact monitoring of the driver's fatigue driving condition in the vehicle, but also supports the automatic control closed-loop processing through the Telematics-Box and the cloud servo servo module. Based on the collected data uploaded to the cloud servo module 30, the driver fatigue state level can be judged, and the cloud servo module 30 can directly command the driver's fatigue state and issue an order to automatically control the automobile engine, the transmission, etc., to achieve the driver's unconscious control. When the car is running, the cloud servo module 30 can automatically take over to control the car to slow down and force the car to stop.

The method obtains driving data through the built-in GPS data of the driving data acquisition module 24 and the Telematics-Box of the gyroscope, the geomagnetic sensor and the barometric sensor, and can assist the monitoring of the driving behavior of the driver and upload it to the cloud.
