[0023] The GPS system and the WIFI module are electrically connected to the detection domain controller.

[0024] Working principle: When using the present utility model, when the speed reaches a predetermined value, the whole set of systems is triggered to work. By analyzing the wind volume data collected by the wind direction and speed sensor within a preset time domain in the past, as well as the local meteorological wind volume data obtained by the GPS module and the WIFI module, the possible wind disturbance scenarios of crosswinds on the vehicle in the future period are predicted, and a warning light is given by the predicted wind disturbance warning light. During this period, the pressure detector used by the pressure detection module matches the crosswind measurement value to improve the accuracy of the response threshold. When the detected lateral force is greater than or equal to the predetermined value affecting the safe driving of a mini car, and the angle detector detects the steering wheel angle and determines it as the angle value of straight driving, an alarm response is triggered. According to the state of the alarm response, when the gyroscope detection module used by the gyroscope module detects that the vehicle has a lateral offset, the steering wheel vibration response can be triggered. By accompanying the vibration response during the alarm response, the response intensity is increased, and the perception of the vehicle driver is also improved. The whole set of systems adopts a series of detection modules to collect information factors affecting vehicle driving safety, and processes the collected information through a processor to determine whether it is necessary to take a response to warn the driver.

By processing the collected data, logic, and providing a warning effect to the driver, and according to the analyzed wind direction and speed data collected, the possible wind disturbance situation in the future period is predicted and warned, which can improve the safety of a mini car during high-speed driving.

Use and the value after time p Through As the distance r The weight function w of i i ​As a correction method, output the predicted values x of wind speed and wind direction t+p . As data comparison x t and x t-p The predicted value x can be simply verified t+p , that is, x t+p = x t +(x t -x t-p ). At the same time, combined with the local meteorological data obtained through networking, if the local wind direction is on both sides (downwind and headwind) of the vehicle, the prediction response is a normal warning; if it is on the left and right sides (crosswind), the indicator response should be corrected according to the local meteorological wind speed below the normal prediction threshold (the light is on below the normal prediction threshold).
