FIG. 6A depicts an example mapping relationship among multiple emergency modes, and geofence functions according to an exemplary embodiment of the present disclosure. FIG. 6B depicts example geofence functions of FIG. 6A according to an exemplary embodiment of the present disclosure.

Referring now to FIGS. 6A and 6B, the emergency modes 1410_1 to 1410_M have different degrees of emergencies one from another which are respectively mapped to different geofence functions G_{E_}1(x) to G_{E_M}(x). For example, as the working mode is changed from the emergency mode 1410_1 to the emergency mode 1410_M, the degree of emergency increases, and thus, the size of corresponding geofence is increased from the geofence G_{E_1}(x) to G_{E_M}(x). as shown in FIG. 6B. Although it is illustrated in FIG. 6B that shapes of the geofences are similar to one to another, exemplary embodiments of the present disclosure are not limited thereto. For example, the shapes thereof can be varied if necessary.

In addition, referring back to FIG. 5, the EV operator may directly determine and select a particular intent from among the intents 1420_1 to 1420_N based on the information of the emergency situation displayed on the output device 150.
