Step nine: and judging whether the vehicle is really rescued or not according to the judged real brake signal data before and after the vehicle danger-leaving stopping point, such as the gps speed of the stopped vehicle.
For example, the calculation of the speed characteristics before and after parking judges whether the vehicle is subjected to false rescue, and the false rescue is calculated for the condition that a brake signal exists after the vehicle is in danger or the condition that the gps speed of the vehicle is greater than or equal to 60km/h in 24 hours after the vehicle is in danger.
Step ten: and calculating the distance between two stops aiming at the stop points after the danger stop point is judged to obtain the suspected rescue distance.
Step eleven: and evaluating the probability of major accidents of the vehicle according to the emergency deceleration and speed before and after the dangerous stop point and collision rollover alarm data.
