Abstract: PURPOSE: A method for controlling a ban on a cellular phone in a car is provided to decide whether a driving condition of a current car is impossible to use a cellular phone, and to alarm with a loud sound for prohibiting use of the cellular phone, thereby promoting safe driving. CONSTITUTION: When a car is started(S100), an ECU(Electronic Control Unit) decides whether the car is in driving state(S110). If so, the ECU senses receiving/transmitting sounds of a cellular phone through a sensor to decide whether the cellular phone is currently used(S120). If so, the ECU reads a signal inputted from a car driving state sensor to compare outer traffic situations(S130). The ECU decides whether the cellular phone is in unusable state through analyzed data(S140). If so, the ECU operates a car audio driver or an alarming unit to control a loud noise to be generated(S150). The ECU decides whether the cellular phone is not used(S160). If so, the ECU releases a generated alarming sound(S170).
