[0045] Embodiment 1

[0046] See also Figure 1 , shown is a method for emergency takeover of a car in a first embodiment of the present invention, and the method specifically includes steps S01 to S04.

[0047] S01, obtaining monitoring information of a preset sensing device, image information of a preset image capturing device, and vehicle information of a preset vehicle monitoring device, determining the current physical condition information of the driver through a preset algorithm according to the monitoring information, and determining the current appearance condition information of the driver and the vehicle condition information according to the image information and the vehicle information respectively;

[0048] Specifically, the preset sensing device at least includes a photoelectric sensor and an LED light source. The step of determining the driver's current physical condition information through a preset algorithm according to the monitoring information includes: determining the change information of the attenuated light after the light of the LED light source is reflected and absorbed by human blood vessels and human tissues according to the monitoring information; determining the driver's heart rate and blood oxygen saturation, that is, physical condition information, through photoplethysmography according to the change information. Further, the step of determining the driver's current appearance condition information according to the image information includes: determining the driver's image information corresponding to the image information at the current moment and the historical image information before the preset time length; comparing the difference between the driver's image information at two different moments, and judging whether the difference is greater than the preset value; if so, comparing the difference between the image information at the current moment and the standard image in the database, and outputting the difference value. In addition, the step of determining the vehicle condition information according to the vehicle information includes: determining the real-time vehicle speed information and driving direction information of the current vehicle according to the vehicle information, and determining the real-time change amplitude value corresponding to the real-time vehicle speed information and driving direction information, that is, vehicle status information.

[0049] It should be noted that the blood flow rate in the artery changes with the heart, causing its ability to absorb light to change accordingly; the electrical signal converted by the photoelectric sensor is used to quantify its fluctuations, and the pulse change can be measured after processing. There is a certain ratio between the oxygenated hemoglobin HbO2 and hemoglobin Hb contained in the blood, and the two have different light absorption coefficients for different wavelengths. Based on this, the ratio of the two hemoglobins can be calculated through the electrical signal of the photoelectric sensor to obtain the blood oxygen saturation. By determining the driver's pulse and blood oxygen saturation, it is possible to judge whether the driver is in a state of consciousness. In addition, by judging whether there is a sudden large change through the driver's appearance, that is, the driver's facial features, external body posture, etc., it is determined whether the driver is driving normally, avoiding misjudgment of the driver's state due to occasional pulse changes in the driver's body. In addition, it is necessary to make a comprehensive judgment in combination with the vehicle state to avoid misjudgment.

[0050] S02, respectively comparing the physical condition information, the appearance condition information and the vehicle condition information with preset judgment conditions, and judging whether all the information satisfies the preset judgment conditions;

[0051] Specifically, the steps of comparing the physical condition information, the appearance condition information and the vehicle condition information with preset judgment conditions respectively include: comparing the heart rate and the blood oxygen saturation of the current driver with the range values ​​of the driver's historical heart rate and historical blood oxygen saturation to determine whether they are within the preset health value range; comparing the difference value with the normal difference value to determine whether it is less than the normal difference value; obtaining navigation information to determine the theoretical change amplitude value of the current vehicle, comparing the real-time change amplitude value with the theoretical change amplitude value to determine whether the ratio between the two is within the preset amplitude change range.

[0052] In addition, when judging the vehicle condition, the changes in vehicle speed and the vehicle's driving direction are mainly judged to determine whether the vehicle suddenly accelerates, decelerates, or turns. In addition, to ensure the accuracy of the judgment, it is necessary to make a comprehensive judgment based on the navigation information, that is, to determine based on the current driving condition and navigation information, whether the vehicle's driving speed and direction change are within a preset range, that is, whether the deviation between the vehicle's driving path and the path to be driven and the navigation path is within a preset range, so as to determine whether the vehicle is driving normally, so as to improve the accuracy of vehicle condition judgment.

[0053] S03, if not, the vehicle enters a first-level abnormal state, generates corresponding warning measures, and determines whether the driver performs a feedback operation corresponding to the warning measures within a preset time;

[0054] Specifically, the steps of generating corresponding warning measures and judging whether the driver performs the feedback operation corresponding to the warning measures within a preset time include: controlling the start of the wipers, the lifting of the windows, and the central control display screen to display a warning and issue a warning voice, and randomly determining the feedback operation and broadcasting it to the driver through voice; judging whether the driver performs the feedback operation within the preset time. Specifically, the feedback operation can be turning off the wipers, opening the windows, reading aloud specific words, etc. Through random feedback operations, the driver's habitual feedback behavior is avoided, which affects the accuracy of the method.

[0055] S04, if not, the vehicle enters the secondary abnormal state and executes the preset emergency measures.

[0056] Specifically, the steps for the vehicle to enter the second-level abnormal state and execute preset emergency measures include: cutting off the driver's control of the vehicle and controlling the vehicle through the automatic driving system; controlling the vehicle to turn on the double flashes, and controlling the vehicle to slow down and pull over, and issuing an alarm and sending positioning information.

[0057] In summary, the automobile emergency takeover method in the above-mentioned embodiment of the present invention obtains corresponding monitoring information through multiple preset devices, and determines the driver's physical condition, appearance condition and vehicle condition based on the monitoring information, and then compares these conditions with the preset judgment conditions to determine whether they meet the preset judgment conditions. If they meet, it means that the current driver is in a normal driving condition. If they do not meet, it enters a first-level abnormal state and generates an alarm to enable the driver to make corresponding feedback to prevent the system's automatic judgment from making mistakes. If the driver does not provide feedback in time, it proves that the current driver is in an abnormal driving condition, and then enters a second-level abnormal state, thereby executing emergency measures to make the vehicle pull over and alarm, thereby avoiding the situation where the driver suddenly loses consciousness and causes a traffic accident, and through timely emergency judgment and measures, the driver can be treated in time. Therefore, the present invention solves the problem of the driver suddenly losing consciousness in the prior art, resulting in misoperation of the vehicle and causing a traffic accident.
