Although it is illustrated in FIG. 5 that the selection menu includes both the emergency modes 1410_1 to 1410_M and the intents 1420_1 to 1420_N, exemplary embodiments of the present disclosure are not limited thereto. In some examples, the system allows only one group of the emergency modes 1410_1 to 1410_M and the intents 1420_1 to 1420_N to be used for the working mode selection of the EV 10, so that either of the emergency modes 1410_1 to 1410_M and the intents 1420_1 to 1420_N might not be shown or provided in the selection menu of FIG. 5.
In one embodiment, the working mode of the EV 10 can be selected (or determined) in an automatic manner by the emergency subscriber device 100 of the EV 10, which will be described with reference to FIG. 4B.
FIG. 4B depicts a flow chart of a method for selecting a working mode of an EV and varying a size or shape of a geofence based on the selected working mode according to an exemplary embodiment of the present disclosure.
