PROBLEM TO BE SOLVED: To reliably output the false running noise adapted to meet the actual situation. SOLUTION: When a false running noise generation device 1 mounted on an electric-driven vehicle and a false running noise generation device 1 of a portable terminal 2, a road side machine 3 and other vehicle present outside the electric-driven vehicle are communicated with each other, the false running noise is output according to the false running noise output request information on the control of the output of the transmitted false running noise, and thus, the false running noise can be output without being affected by a dead angle or the like of a risk object detection device 12 of one's own vehicle for detecting a risk object if the risk object is present near one's own vehicle or if the possibility of its presence is high.
