BACKGROUND

Technical Field

The present disclosure relates to a method for energy-saving driving for a mobility device and a navigation system to which the method is applied, and more particularly, to a method of providing a route in response to a user's request to activate an energy-saving mode and a navigation system to which the method is applied.

Description of the Related Art

With the recent revitalization of the supply of electric vehicles, the supply of electric vehicle charging stations is also accelerating. However, compared to a supply rate of the electric vehicles, the supply of electric vehicle charging stations is still poor, and electric vehicle users are having difficulty in charging.

Accordingly, electric vehicle users may find it difficult to reach their desired destination due to a lack of a battery charge amount. In order to solve the above problem, a conventional technology for making sure of a maximum available driving distance through an energy-saving mode that restricts excessive output waste such as rapid acceleration of an electric vehicle has been proposed.

However, since the above-described conventional technology activates and deactivates the energy-saving mode through a user's input, when the user does not want the energy-saving mode, the user should perform an input for deactivating the energy-saving mode separately while driving. In addition, since the conventional energy-saving mode technology only restricts the output of the electric vehicle, there is a problem that the effect of making sure of the available driving distance is also insignificant.

Accordingly, the energy-saving mode driving technology of the electric vehicle is required to make sure of a maximum available driving distance by automatically activating and deactivating the energy-saving mode in accordance with a driving state of the electric vehicle and deactivating the electric vehicle's electronic control function, but this technology has not been provided.
