The invention discloses a road condition data dynamic acquisition method and system based on an automobile data recorder, and relates to the technical field of traffic road condition acquisition, the system monitors road conditions in front of a vehicle in real time, including the vehicle speed, the vehicle distance, the lane line condition and the like, and accurate evaluation of the traffic congestion degree can be provided through calculation of a congestion coefficient Yd. And the data acquisition frequency is intelligently adjusted through the self-adaptive trigger acquisition unit. When the traffic is smooth, the data acquisition frequency is reduced to save electric energy and reduce the cost. And when traffic jam occurs, the data acquisition frequency is increased to better monitor traffic events, and real-time data support is provided. And resource utilization optimization is promoted. The system can detect traffic events, such as vehicle spacing anomalies and road accidents. Therefore, road events c
