System for generating pseudo driving sound
A pseudo driving sound playback system includes a server and an in-vehicle device. The server includes a database of pseudo sound data sets in which sound elements of engine sound are associated with each of a plurality of predefined driving states for each of a plurality of passenger gasoline vehicle models. The in-vehicle device determines one of a plurality of vehicle models based on received input of a user, downloads a pseudo sound data set of the vehicle model from the server, selects a sound element according to the detected driving state from the pseudo sound data set, and sequentially outputs the sound element as sound from a speaker.
