S4, judging whether the face change information is matched with preset face information or not;
the preset face information refers to information of the driver during normal driving, such as closing time of eyes, closing degree, degree of change of mouth angle, and the like. Taking the closing time of eyes as an example, judging whether the face change information is matched with the preset face information, namely, acquiring the closing time of eyes of a target driver in the driving process, and judging whether the face change information is identical with the closing time of eyes in the preset face information, wherein a certain error value can be provided, the error value can be set according to actual conditions, if the face change information is identical in the error range value, otherwise, the face change information is different.
S5, if the two types of the information are not matched, acquiring a reminding instruction;
if the driver is not matched, the target driver is proved to be possibly in fatigue driving, and eyes are closed for a long time, so that the safety of the driver is ensured as much as possible, and a reminding instruction is acquired at the moment. If the two types of the reminding instructions match, the driver is proved to be in a normal state at the moment, so that the reminding instructions do not need to be acquired at the moment.
S6, controlling a preset discharging device on a steering wheel of the target vehicle to release reminding current based on the reminding instruction so as to remind a target driver;
finally, a preset discharging device on a steering wheel of the target vehicle is controlled to release reminding current according to the reminding instruction, so that a target driver can be stimulated to wake. The reminding current is a current which can ensure the safety of the target driver and can normally act, namely, the life safety of the target driver is not endangered, and the body is not paralyzed, and the like, so that the normal action is not influenced.
The discharging device can be a metal sheet arranged on the steering wheel and is connected with a power supply, and when the metal sheet is electrified, the reminding current can be released, so that the driver is stimulated by the hands of the driver, and the purpose of reminding the driver is achieved. Of course, an alarm sound device can be arranged to remind the driver.

s11, controlling a discharging device to release reminding current according to primary current based on the reminding instruction, and obtaining first feedback data of a target driver;
that is, the reminding current is set in steps in advance, that is, the reminding current comprises a primary current, a middle-level current and a high-level current, the high-level current is larger than the middle-level current, and the middle-level current is larger than the primary current. After the reminding instruction is acquired, the discharging device is controlled to discharge according to the minimum level, namely the primary current, so that the target driver is reminded.
Meanwhile, first feedback data of the target driver are acquired, namely, whether eyes of the target driver are open or not is determined through the image by acquiring the image of the target driver, and whether the eyes of the target driver are closed within a preset duration after the eyes of the target driver are open or not is determined.
S12, judging whether the first feedback data is matched with preset reference data or not;
the reference data is that eyes of the driver are open and are not closed within a preset time period. If the eyes of the target driver are not open, a mismatch is demonstrated, or if the eyes are closed for a preset period of time after opening, a mismatch is demonstrated, and if the eyes are open and not closed for a preset period of time, a match is demonstrated.
S13, if the current is not matched, controlling the discharging device to release reminding current according to the medium-level current based on the reminding instruction, and obtaining second feedback data of a target driver;
if the first feedback data matches the reference data, it is proved that the target driver has been awake at this time, so that the current discharge is stopped at this time. If the first feedback data is not matched with the reference data, the target driver is proved to be not awake at the moment, so that the reminding current of the target driver needs to be increased.
Therefore, the discharge device is controlled to release the reminding current according to the medium-level current based on the reminding instruction at the moment, and second feedback data of the target driver are obtained. The second feedback data is obtained in the same manner as the first feedback data.
S14, judging whether the second feedback data is matched with the reference data or not;
the judging mode of whether the second feedback data is matched with the reference data is the same as the judging mode of whether the first feedback data is matched with the reference data.
S15, if the current is not matched, controlling the discharging device to release reminding current according to the advanced current based on the reminding instruction, and obtaining third feedback data of a target driver;
if the second feedback data matches the reference data, it is proved that the target driver has been awake at this time, so the current discharge is stopped at this time. If the second feedback data is not matched with the reference data, the target driver is proved to be not awake at the moment, so that the reminding current of the target driver needs to be continuously increased.
Therefore, at this time, the discharge device is controlled to discharge the reminding current according to the high-level current based on the reminding instruction, and the third feedback data of the target driver is obtained. The third feedback data is obtained in the same manner as the first feedback data.
S16, judging whether the third feedback data is matched with the reference data;
the judging mode of whether the third feedback data is matched with the reference data is the same as the judging mode of whether the first feedback data is matched with the reference data.
S17, if the third feedback data are matched with the reference data, stopping releasing the reminding current;
if the third feedback data matches the reference data, it is proved that the target driver has been awake at this time, so the discharge of the current is stopped at this time. Therefore, the primary current, the intermediate current and the advanced current are released step by step, so that the reminding intensity of the reminding current can be controlled, the condition reflection of a target driver to a large extent can be avoided as far as possible, and the danger coefficient in the driving process can be reduced as far as possible.
Further, if the third feedback data does not match the reference data, further processing is required, and therefore, in another embodiment, further comprising:
s18, if the third feedback data is not matched with the reference data, acquiring an automatic driving instruction;
s19, controlling the target vehicle to start the automatic driving mode based on the automatic driving instruction.
That is, if the third feedback data does not match the reference data, an automatic driving instruction is acquired at this time and transmitted to the control system of the target vehicle, so that the target vehicle controls the automatic driving mode of the target vehicle to be turned on according to the automatic driving instruction, and the occurrence probability of unnecessary accidents caused by fatigue driving of the target driver can be reduced.
Referring to fig. 3, the target driver has not been awake under the stimulation of the high-level current, at which point it is proved that the target driver may have sudden illness, so in another embodiment, controlling the target vehicle to turn on the automatic driving mode based on the automatic driving instruction includes:
s21, acquiring the current position of a target vehicle;
s22, acquiring a hospital position based on the current position;
s23, acquiring a driving route based on the current position and the hospital position;
s24, controlling the target vehicle to start the automatic driving mode according to the driving route based on the automatic driving instruction.
Specifically, when the driving mode of the target vehicle is controlled to be started, the current position of the target vehicle is firstly obtained, and the obtaining mode can be obtained through a GPS system or other positioning devices. The hospital location is then acquired from the current location, i.e. the location of the hospital closest to the current location is acquired from the current location.
And then, acquiring a driving route according to the current position and the hospital position, generating a route by a navigation system in an acquisition mode, and finally controlling the target vehicle to start an automatic driving mode according to the driving route according to an automatic driving instruction.
And the target vehicle can travel to the hospital according to the travel route, and can send out alarm information after arriving at the hospital, for example, a voice prompt mode reminds doctors or other personnel nearby the target vehicle to timely send the target driver to the hospital for treatment, so that the safety of the driver can be ensured as much as possible.
Referring to fig. 4, in order to further improve the accuracy of determining whether to acquire the alert instruction, in another embodiment, before acquiring the alert instruction, the method further includes:
s31, acquiring the current route state of the target vehicle;
the route state can be obtained by a GPS navigation system, and can also be determined by a gyroscope to determine whether the target vehicle is in straight line or in curve, namely the route state comprises straight line and curve.
S32, when the route state is a straight line, acquiring a current pressure value of the steering wheel;
the hand can grasp the steering wheel when driving straight line generally, and the hand can break away from the steering wheel in a short time when turning, and the pressure that the steering wheel receives is less at this moment, so if the route state is straight line, obtain the current pressure value of steering wheel at this moment, namely the pressure that the target driver held the steering wheel, the acquisition mode can be obtained through pressure sensor detection.
S33, judging whether the current pressure value is larger than a preset pressure value or not;
the preset pressure value is a pressure value when an actual owner of the target vehicle holds the steering wheel in a normal state, namely, a pressure value when the target vehicle runs in a normal straight line.
S34, if yes, not obtaining a reminding instruction;
s35, if not, executing the step of acquiring the reminding instruction;
therefore, if the current pressure value is greater than the preset pressure value, it is proved that the face change information of the target driver is possibly not matched with the preset face information due to tension and the like at the moment, but the current pressure value is greater than the preset pressure value at the moment, it is proved that the target driver is not in fatigue driving, and therefore the reminding instruction is not acquired at the moment.
If the current pressure value is smaller than or equal to the preset pressure value, the target driver is proved to be in a dozing state possibly, so that the body is relaxed, the pressure on the steering wheel is reduced, reminding is needed at the moment, and the step of obtaining a reminding instruction is continued to be executed.
S36, executing the step of acquiring a reminding instruction when the route state is a curve;
