Patent ID: 8831251

Claim:
A method of controlling driving of a pop-up tweeter speaker, the method comprising: (a) determining, by a processor, whether or not opening of the tweeter speaker is normally completed and popping-down the tweeter speaker in response to determining that the opening of the tweeter speaker is not normally completed, wherein the determining is performed while popping-up the tweeter speaker based on a speaker control condition under an ON condition of an accessory (ACC) condition; (b) determining, by the processor, whether or not close of the tweeter speaker is normally completed and popping-up the tweeter speaker in response to determining that the tweeter speaker did not close normally, wherein the determining is performed while popping-down the tweeter speaker based on an OFF condition of one of the speaker control condition and the ACC condition; and (c) maintaining a position state of the tweeter speaker until the speaker control condition or the ACC condition becomes an OFF condition when popping-down the tweeter speaker in (a) or popping-up the tweeter speaker in (b), wherein the processor determines that the tweeter speaker has not opened normally in (a) when a current value detected from a tweeter speaker driving motor, which supplies a power to a tweeter speaker transfer unit for ascending or descending the tweeter speaker, exceeds a preset current value, and wherein the processor determines that the tweeter speaker has not closed normally in (b) when the current value detected from the tweeter speaker driving motor exceeds the preset current value.
