PROBLEM TO BE SOLVED: To provide an in-vehicle warning device capable of performing sufficient warning without making a driver uncomfortable or troublesome.;SOLUTION: Information about a certain object having the possibility of contacting the own vehicle is detected, as relative situations being phenomenon outside the vehicle related to the traveling of the own vehicle (S100). In order to form a sound field assuming that there is a virtual wall in a vehicle interior, a virtual wall parameter about the virtual wall is set in accordance with the relative situations (S120). When it is determined that warning is necessary (S110: YES), pseudo-noise is generated by using noise data on the basis of the virtual wall parameter (S140), and audio effect of audio sound is adjusted using audio data on the basis of the virtual wall parameter (S150). Thereafter, the pseudo-noise and the audio sound are superimposed and output (S160, S170), where the central position of the virtual wall is set in the vicinity of left or right ear of a driver.;COPYRIGHT: (C)2013,JPO&INPIT
