A method for extracting empirical data about vehicle travel, comprising: acquiring driving data when a vehicle is traveling, and determining whether the vehicle is steering according to the driving data; when the vehicle is steering, determining whether the vehicle is in a steady state during the steering operation according to the driving data; and if yes, processing the driving data and saving the same as empirical data used in an automatic driving process. Single-structure steering data obtained during automatic driving may be avoided well by acquiring driving data during steady steering of the vehicle and using the driving data as empirical data about automatic driving, so that the steering process may also use the corresponding empirical data to make a determination for steering, thus improving the traveling and steering stability of the vehicle, and thereby maintaining safe travel of the vehicle. Further disclosed in the present application are a device for extracting empirical data about vehicle travel and the vehicle, which have the above-described advantageous effects.
