IPC: H04B1/10
Filed: 2002-04-20
Abstract: PURPOSE: A device for removing noise of a mobile communication terminal is provided to exactly sense a user's signal and peripheral signals by using two microphones, thereby removing unwanted peripheral noise. CONSTITUTION: The first microphone(100) is attached to a position to which a user's signal is transmitted, and inputs the user's signal including peripheral signals. The second microphone(200) is attached to a position for recognizing signal characteristics, size, and peripheral sounds, and inputs the peripheral signals including the user's signal. An analog/digital converter(300) converts the signals inputted through the first and the second microphones(100,200) into digital signals. An audio processor(400) processes the outputted signals of the converter(300), and outputs a user' signal only whose noise is removed. A transmitter(500) transmits the outputted user's signal.

IPC: B60W10/18
Filed: 2002-05-29
Abstract: PURPOSE: To exactly and effectively prevent rapid fluctuation of vehicular deceleration caused by rapid reduction of regenerative braking force in initiation of anti-skid control. CONSTITUTION: Target braking forces Fbft and Fbrt of front and rear wheels are calculated on the basis of a braking manipulated variable of a driver and a front and rear wheel braking force distribution ratio (S10-50). Target regenerative braking forces Frgft and Frgrt of the front and rear wheels are calculated on the basis of the target braking forces so that regenerative efficiency is maximized (S60). Since there is high probability that the anti-skid control will be initiated when a sudden braking operation or a braking operation during vehicular deceleration is performed by the driver or when a vehicular side-skid speed is high, the target regenerative braking forces are gradually reduced and target friction braking forces are gradually increased (S76A-78 and S88A-92). When the anti-skid control is initiated, the target regenerative braking forces are set at 0 (S82 and 96).
