Abstract
Disclosed is a vehicle-like sound generation method wherein an acquisition unit (730A) refers to map information contained in a memory unit (710) based on the current position of a vehicle (MV) detected by a position detection unit (720), acquires lane information including the number of lanes on the road the vehicle (MV) is currently driving on, and sends the acquired lane information to a determination unit (740). Then, the determination unit (740) determines the range of the vehicle-like sound output towards the exterior of the vehicle based on the lane information sent by the acquisition unit (730A). Next, a control unit (750) calculates the volume setting for the vehicle-like sound output from the left and right speakers of a sound output unit (760) based on the determined range. Thus, output of the vehicle-like sound can be controlled while taking into account the probability that persons to be notified are present in surroundings which change due to the type of road currently being driven on.
