The invention discloses an intelligent detection method and particularly relates to a collision behavior real-time detection method based on automobile intelligent terminal data. According to the collision behavior real-time detection method, the severity of collision is determined according to the longitudinal acceleration and the lateral incline angle. The collision behavior real-time detection method comprises the following steps that longitudinal acceleration data in the automobile driving process are extracted in real time, threshold judgment is conducted, and after the requirement for the threshold value is met, the next step is carried out; the total fifteen data before and after the collision occurrence time point are extracted and preprocessed, and a model is built to judge whether the data meet collision characteristics or not; speed data within 30 seconds after collision are obtained, and whether the speed is decreased to zero finally is judged; and gyroscope data within nine seconds after the requirement for the threshold value is met are selected, the rotating angle is calculated, and whether the rotating angle meets the requirement or not is judged. By means of the collision behavior real-time detection method based on the automobile intelligent terminal data, the safety of a driver can be effectively improved.
