Classification: CPC B  G | IPC B  G

Claim 0:
1. A pseudo driving sound playback system comprising:
a server; and
an in-vehicle device, wherein
the server includes,
a database which stores a plurality 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 includes,
a communication unit which performs data communication with the server,
a display unit,
an input unit which accepts input from a user,
a storage unit,
a detection unit which continuously detects the driving state of a passenger car equipped with the in-vehicle device,
a sound output unit which outputs the sound element to the inside of the passenger car, and
a controller, and
the controller
determines any one of the plurality of vehicle models based on the input of the user received by the input unit,
requests the determined vehicle model to the server via the communication unit,
downloads a pseudo sound data set corresponding to the vehicle model from the server as a response to the request and stores the pseudo sound data set in the storage unit,
selects the sound element according to the driving state detected by the detection unit from the pseudo sound data set and sequentially outputs the sound element as sound from the sound output unit,
generates virtual environmental sound corresponding to the detected driving state and outputs the virtual environmental sound to the inside of the vehicle, and
switches on/off of output of the virtual environmental sound according to setting.
