A method of controlling an electric latch installed on a door of a vehicle to lock or unlock the door by being operated by a motor, the method comprising:
- (a) operating an inner button to enable a passenger to exit the vehicle;
- (b) determining whether there is an error in a state where the vehicle has been started;
- (c) determining whether a vehicle speed is input to a control unit;
- (d) when the vehicle speed is not input, inducing an emergency lever to guide a use of the emergency lever connected to the electric latch by a cable;
- and
- (e) when the emergency lever is pulled, releasing the electric latch by the cable,
- wherein the error determination in step (b) and the absence of vehicle speed input in step (d) are caused by an error in in-vehicle controller area network (CAN) communication;
- and
- wherein, in step (d), the control unit induces the passenger to use the emergency lever while prohibiting the electric latch from being released by the inner button, and
- wherein the inducing of the emergency lever further comprises controlling, using the control unit, display of a phrase on a cluster guiding the use of the emergency lever and output, as a voice or an alarm sound, through a speaker guiding the use of the emergency lever.

- (b) determining whether there is an error in a state where the vehicle has been started;
- (c) determining whether a vehicle speed is input to a control unit;
- (d) when the vehicle speed is not input, activating, by the control unit, an emergency lever connected to the electric latch by a cable;
- and
- (e) when the emergency lever is pulled, releasing the electric latch by the cable,
- wherein the error determination in step (b) and the absence of vehicle speed input in step (d) are caused by an error in in-vehicle controller area network (CAN) communication;
- and
- wherein, in step (d), the control unit induces a passenger to use the emergency lever and
- wherein, after activating the emergency lever, displaying through a cluster and output through a speaker, by the control unit, a guide for using the emergency lever.
