Specifically, the help seeking information comprises an in-vehicle image, an out-vehicle image and a vehicle position which are collected by a vehicle-mounted camera.
Further, the judging the abnormal state level includes:
when the at least one type of vehicle state data is larger than a first threshold value of the type of sensor state data and smaller than a second threshold value of the type of sensor state data, the abnormal state grade is one grade;
when the state data of at least one type of vehicle is larger than a second threshold value of the state data of the type of sensor, the abnormal state grade is two grades;
if the abnormal state level is two-level and no help inquiry response is received within the time threshold, the abnormal state level is three-level.
The first threshold and the second threshold of the various sensor state data mentioned in this embodiment are values obtained according to various test tests of the vehicle, wherein the first threshold is a risk threshold, and when data acquired by the vehicle-mounted sensor exceeds the first threshold, the vehicle has a risk of an accident; the second threshold is an accident threshold, and when the data collected by the vehicle sensor exceeds the second threshold, the vehicle has an accident.
In addition, when the driver makes a help request through the help button and/or the voice receiving unit, the abnormal state level is three levels.

if the same license plate appears at 3-5 continuous intersections, judging that the license plate is tracked and generating abnormal state information;
and displaying abnormal state information by the vehicle-mounted display screen, and broadcasting the abnormal state information and prompting the tracked risk by voice.
In one embodiment, the method for processing the abnormal state of the vehicle based on the internet of vehicles, as shown in fig. 3, includes:
s110, the vehicle-mounted sensors acquire vehicle state data in real time and transmit the vehicle state data to the control subsystem, the control subsystem compares the received vehicle state data with set data thresholds of various sensors to judge whether the vehicle is in an abnormal state, if the vehicle state data detected by the sensors is smaller than a set first threshold, the vehicle state is judged to be normal, the step S110 is executed again, if the vehicle state data detected by at least one of the sensors is larger than a set first threshold and smaller than a second threshold, the step S120 is skipped, and if the vehicle state data detected by at least one of the sensors is larger than a set second threshold, the step S130 is skipped.
And S120, the control subsystem judges that the vehicle state is in a primary abnormal state and carries out driving risk reminding through the vehicle-mounted display screen and the voice interaction system.
S130, the control subsystem judges that the vehicle state is in a secondary abnormal state, reminds and inquires whether a driver needs to send help seeking information to an emergency contact person or not on the vehicle-mounted display screen, meanwhile, the driver can select whether the help seeking information is sent or not through the touch display screen or reply through voice, and the situation that the driver is not free to operate the display screen in an emergency is avoided. If the driver confirms that the help-seeking information needs to be sent to the emergency contact person, or the feedback of the driver is not received within 30S, the control subsystem judges that the vehicle state is in the three-stage abnormal state, and the step S140 is skipped. If the driver selects that the vehicle state is not required to be sent to the emergency contact, the control subsystem judges that the vehicle state is normal, the driver can process the abnormal state of the vehicle, and the driver does not send a help seeking instruction and skips back to the step S110.
In this embodiment, the driver may handle the abnormal state of the vehicle, where although the vehicle-mounted tilt angle sensor exceeds the threshold at a certain time, the driver avoids the vehicle from rolling over through a driving technique.
S140, the control subsystem judges that the driver needs to send help seeking information, controls the control subsystem to turn on the vehicle-mounted camera to record real-time conditions inside and outside the vehicle, and sends the help seeking information (including images inside and outside the vehicle and GPS positioning) to the emergency contact through the Internet of vehicles system.
In practical application, even if the vehicle state data acquired by all the sensors are smaller than the set threshold value, the driver perceives that the vehicle state is abnormal or the state of the driver is abnormal, the driver selects to send help-seeking information by controlling the vehicle-mounted display screen or the voice interaction system, the step S140 is skipped, the control subsystem receives the instruction of sending the help-seeking information, then the vehicle-mounted camera is controlled to record images inside and outside the vehicle, and the help-seeking information is sent to the emergency contact through the internet of vehicles.
In the embodiment, the driver perceives the abnormal condition of the vehicle state, including the vehicle brake failure or the vehicle-mounted sensor abnormality, but the vehicle has the accidents of collision, rollover or wading and the like; the abnormal state of the driver comprises sudden diseases, situations that the driver finds to be tracked or clamped and the like.
