The invention provides a method for judging vehicle running road types based on a hidden Markov model. The method includes the steps: depicting processes of a vehicle running on different road types into the hidden Markov model; training the hidden Markov model to obtain a hidden Markov model suitable for judging the vehicle running road types; judging the vehicle running road types on line by the aid of the trained hidden Markov model. The method is high in judging accuracy and low in delay, driving safety of a driver is further guaranteed, on the other hand, the hidden Markov model is depicted based on an acceleration sensor and a GPS (global positioning system) device of a smart phone placed in a vehicle, requirements on hardware are reduced, and universality of the judging method is improved.
