A self-driving vehicle includes a motor, a driving source configured to drive the motor, a vehicle-traveling-time setter setting a vehicle traveling time determined by a passenger, thereby generating a passenger-set, vehicle traveling time, and a processor providing a traveling application providing assistance in driving the self-driving vehicle. The processor also detects the remaining amount of power of the driving source and calculates the amount of time the self-driving vehicle will travel based on the detected remaining amount of power of the driving source. Also, the processor searches and determines a route the vehicle can complete within the passenger-set, vehicle traveling time when the calculated travelable time is longer than the passenger-set, vehicle traveling time.
