The invention belongs to the technical field of vehicle engineering, and particularly relates to a driving data processing method and device, a computer storage medium and a controller. Based on combined low-pass filtering and multi-rolling-resistance model moving average, processing and information fusion of the vehicle quality and related data in the running process are achieved; the convergence judgment process and the moving average process are favorable for eliminating interference information and improving the credibility and the precision of the processing process; by fusing the vehicle weight estimation process and the rolling resistance coefficient estimation process, segmented joint identification of related data is also realized, the estimation effect is further improved, and the application scene is expanded; the treatment process gets rid of the dependence of related technologies on factors such as vehicle types, road types and weather conditions, and the resistance coefficient does not need to be calibrated in advance; the method can be widely applied to different vehicle types, and can obtain relatively stable output and precision for different road types; the typical rolling resistance coefficient reference value disclosed by the embodiment of the invention is also verified in systems such as passenger cars and the like.
