A system providing remaining driving information of a vehicle based on user behavior includes a detection unit, a memory unit and a computation unit. The system stores information acquired by the detection unit during a moving progress of the vehicle to the memory unit to serve as history information, and accordingly generates a personalized model. The computation unit acquires current remaining energy information and at least one set of real-time information through the detection unit, inputs the same to the personalized model, and outputs a predictive remaining driving information to a display interface. The personalized model is generated based on user habits and behavior of various users, used vehicle and driving environment, and is thus capable of generating the personalized predictive remaining driving information. Accordingly, the personalized model integrating various personal factors, vehicle parameters and environment parameters can provide more accurate predictive information for reference of a user.
