The invention discloses a method for estimating the remaining driving range of a pure electric vehicle. The invention belongs to the technical field of electric automobiles. The invention aims to provide a method for estimating the remaining driving range of a pure electric vehicle based on map information and an iterative SVR model. The method comprises the following steps: (1) analyzing influence factors influencing the driving range according to an automobile physical model and actual data; (2) carrying out fragment division on the driving condition data, and extracting feature parameters of fragments; (3) based on the characteristic parameters, carrying out category division on the working condition fragments through a clustering method; (4) establishing an SVR model for calculating the SOC decrease value per unit mileage; (5) acquiring road information by using a Baidu map API path planning function, and predicting future driving conditions; and (6) through loop iteration of the SVR model, combining the current SOC value, the working condition parameters and the temperature value, and predicting the remaining driving range of the automobile.
