The embodiment of the invention provides an abnormal driving behavior recognition method and device and a terminal device, and relates to the field of data processing. An accelerated speed sensor and/or a direction sensor on the terminal are/is used for recording state data for indicating the running state of a vehicle, whether or not an abnormal driving behavior exists in the vehicle is judged on the basis of a GPS on the terminal and the recorded state data, and when it is judged that the abnormal driving behavior exists in the vehicle, safe pre-warning is conducted for users. On the basis of the portability and universality of a smart phone, driving behaviors of a driver are collected through the sensor on the terminal, the abnormal driving behavior can be recognized, the cost is reduced, the driver can be helped to change driving habits, and the driving safety is improved.
