step S1: the method includes acquiring vehicle steering wheel state information, wherein the vehicle steering wheel state information includes at least one of a pressure value of an outer ring of a steering wheel and steering wheel angle information.
Specifically, the outer ring of the steering wheel refers to a handle disc of the steering wheel, and pressure sensors are uniformly arranged on the handle disc of the steering wheel to detect pressure values of all parts of the outer ring of the steering wheel. The steering wheel angle information includes an angular velocity and an angle amplitude, and is detected by an angle sensor provided on the steering wheel.
In one embodiment, step S2: acquiring vehicle steering wheel state information, comprising: acquiring the running speed of a vehicle; and when the running speed of the vehicle is greater than the preset speed value, acquiring the state information of the steering wheel of the vehicle.
The public transportation accident caused by abnormal steering is generally in a state that the vehicle runs at a high speed, and due to the characteristics of the public transportation vehicle, the vehicle is in a running state and a parking state at intervals, and in the parking state, the detection of the steering wheel state information may be abnormal due to the relaxation behavior of the driver, such as releasing the steering wheel to process other things, so that the subsequent information processing is judged incorrectly. Therefore, it is necessary to detect the current traveling speed of the vehicle before acquiring the steering wheel state information. It should be noted that the preset speed value may be set by taking comprehensive consideration of the performance of the vehicle, the road condition, the road traffic flow, and the like.
Step S2: when the vehicle steering wheel state information is matched with the preset dangerous driving condition, emergency braking is carried out, and/or the steering wheel rotating amplitude is limited, and/or the rotating speed of the steering wheel is limited, and/or the vehicle speed is controlled within a preset speed range.

Therefore, in one embodiment, the preset pressure values may include a preset minimum pressure value and a preset maximum pressure value. Correspondingly, when the sum of the pressure values is smaller than the preset minimum pressure value or larger than the preset maximum pressure value within the preset time, emergency braking is carried out, and/or the rotation amplitude of the steering wheel is limited, and/or the rotation speed of the steering wheel is limited, and/or the vehicle speed is controlled within the preset speed range.
In one embodiment, step S2: when the vehicle steering wheel state information is matched with the preset dangerous driving condition, emergency braking is carried out, and/or the steering wheel rotating amplitude is limited, and/or the rotating speed of the steering wheel is limited, and/or the vehicle speed is controlled within a preset speed range, and the method comprises the following steps: analyzing the pressure value; when the pressure value is larger than the specific value, judging that the pressure value is an effective pressure value; and when the sum of the number of the effective pressure values in the preset time is larger than the preset value, emergency braking is carried out, and/or the rotating amplitude of the steering wheel is limited, and/or the rotating speed of the steering wheel is limited, and/or the vehicle speed is controlled within a preset speed range.

It should be noted that, when there may be a heavy object falling on the steering wheel, the pressure value of the portion is greater than a specific value, and therefore, in one embodiment, step S2: when the vehicle steering wheel state information is matched with the preset dangerous driving condition, emergency braking is carried out, and/or the steering wheel rotating amplitude is limited, and/or the rotating speed of the steering wheel is limited, and/or the vehicle speed is controlled within a preset speed range, and the method comprises the following steps: analyzing the pressure value; when the pressure value is larger than the specific value in the preset time, judging that the pressure value is an effective pressure value; and when the sum of the number of the effective pressure values in the preset time is larger than the preset value, emergency braking is carried out, and/or the rotating amplitude of the steering wheel is limited, and/or the rotating speed of the steering wheel is limited, and/or the vehicle speed is controlled within a preset speed range.
In one embodiment, step S2: when the vehicle steering wheel state information is matched with the preset dangerous driving condition, emergency braking is carried out, and/or the steering wheel rotating amplitude is limited, and/or the rotating speed of the steering wheel is limited, and/or the vehicle speed is controlled within a preset speed range, and the method comprises the following steps: analyzing steering wheel angle information, wherein the steering wheel angle information comprises an angle or an angular speed; when the angular speed is larger than the preset angular speed value or the rotation angle changes back and forth within the preset time, emergency braking is carried out, and/or the rotation amplitude of the steering wheel is limited, and/or the rotation speed of the steering wheel is limited, and/or the vehicle speed is controlled within the preset speed range.
Specifically, a commonly used steering wheel angle sensor employs a three-gear mechanical structure to measure the angle of rotation and the number of turns made. The big gear rotates along with the steering wheel pipe column, the number of teeth of the two small gears is different by 1, and the big gear and the sensor shell are fixed on the vehicle body together and do not rotate along with the rotation of the steering wheel. The two pinions respectively acquire rotating angles rotating along with the steering wheel, different numbers of turns differ by a specific angle due to a difference of one tooth, and the absolute rotating angle of the steering wheel is obtained through calculation. The preset angular speed in the embodiment is set according to historical data in the vehicle driving record and/or parameter requirements of the vehicle. It should be noted that the back and forth represents the change of the rotation direction when the rotation angle is changed back and forth within the preset time.
In one embodiment, step S2: when the vehicle steering wheel state information is matched with the preset dangerous driving condition, after emergency braking is carried out and/or the steering wheel rotating amplitude is limited and/or the rotating speed of the steering wheel is limited and/or the vehicle speed is controlled within a preset speed range, the method further comprises the following steps: when an alarm instruction is received, vehicle position information is acquired in real time; acquiring character information around a driving seat; and sending alarm information to an alarm center, wherein the alarm information comprises vehicle position information and character information.

Under different environments, the traffic accident casualty amount can be reduced by controlling the state of the car window.
In one embodiment, step S3: the steps of taking corresponding safety measures according to the environmental information of the vehicle comprise: acquiring environmental information outside the vehicle; and when the vehicle is judged to be in the water according to the environmental information, all windows of the vehicle are automatically opened.
In one embodiment, step S3: the steps of taking corresponding safety measures according to the environmental information of the vehicle comprise: acquiring environmental information outside the vehicle; and when the flow of the vehicles around the vehicle is judged to be large according to the environmental information, all windows of the vehicle are automatically closed.
Specifically, the traffic flow around the vehicle can be acquired in real time according to the car networking system, and because in a high-speed state, the abnormal steering of the vehicle can cause the passenger to throw out of the vehicle to cause casualties, especially when the traffic flow is large, the passenger can be collided by the coming and going vehicle, and therefore the window is closed at the moment to ensure that the passenger receives extra injury. It should be noted that, in an embodiment, when it is determined that the traffic flow around the vehicle is large according to the environmental information, the step of automatically closing all windows of the vehicle further includes: and acquiring the running speed of the vehicle, and automatically opening all windows of the vehicle when the running speed is less than a preset safety value.
