The driving tendency includes at least one of RPM (Revolution Per Minute) of the vehicle, torque, and running speed. Accordingly, a plurality of sound data can be stored in the table in accordance with the driving tendency for one vehicle. That is, if the running speed is changed even if the RPM and the torque are the same, the corresponding acoustic data is also changed, so that the acoustic data is stored in the table for each driving tendency. This is because the sound volume, sound volume and sound intensity of the sound data may be different depending on the driving tendency. In addition, the acoustic data may be further subdivided for each vehicle type as well as the vehicle type, and then stored in a table.

The information collecting unit 161 can collect RPM, torque, running speed, and the like provided from the ECU 10 as running information. The target vehicle refers to a vehicle in which the device 100 is currently installed.

The data selection unit 162 selects sound data corresponding to the travel information collected in real time among the sound data stored for a plurality of vehicle types as a driving sound effect of the target vehicle. More specifically, the data selection unit 162 identifies the vehicle type of the target vehicle, identifies the desired vehicle selected by the user, and identifies the vehicle selected from the table of the storage unit 130 Or selects the most similar sound data as the driving sound effect of the target vehicle.

The screen generating unit 163 generates a screen for selecting a driving sound effect sound of a desired vehicle type among a plurality of vehicle types, that is, a vehicle selection window. The screen generation unit 163 generates a vehicle selection window using the screen configuration data stored in the memory 160.

2 shows an example of a vehicle selection window 200 according to an embodiment of the present invention.

2, vehicle types of a plurality of various vehicles are displayed in the vehicle selection window 200, and even if they are the same type, they are subdivided by year.

The device 100 reproduces the sound data corresponding to the selected vehicle, As driving sound effects.

The playback unit 170 processes the sound data corresponding to the current driving information of the target vehicle and the target vehicle so as to be reproducible or the sound data corresponding to the selected type of vehicle through the vehicle selection window 200 to be reproducible.

The sound data processed to be reproducible is output to the outside through the speaker 175. The speaker 175 is provided not only inside the target vehicle but also outside, and can be provided to the driver as well as the pedestrian. Thus, the pedestrian can also detect the noise of the vehicle in real time and detect that the vehicle is in the vicinity of the pedestrian in advance, thereby avoiding an accident in advance by avoiding the vehicle in advance.

However, even if the user selects a different type of vehicle from the target vehicle, the apparatus 100 confirms the vehicle selected by the user from the table stored in the storage unit 130, And reproduces sound data that matches or is most similar to the running information of the vehicle as driving sound effects.

The control unit 180 controls or manages the overall operation of the apparatus 100 and the above-described operations. For example, when the user selects the driving sound effect reproduction mode through the user selection unit 110, the control unit 180 requests the ECU 10 to provide the driving information, and transmits the driving information provided from the ECU 10 And controls the information collecting unit 161 to collect the information. The control unit 180 controls the data selection unit 162 and the playback unit 170 to confirm the sound data mapped to the same or similar information as the running information of the target vehicle in the table of the storage unit 130, And reproduces and outputs the confirmed sound data as the driving effect sound.

Also, the control unit 180 allows the user to reproduce the confirmed sound data as the driving sound even while the user is listening to the radio or listening to the music through the CD player, so that the radio sound or the CD sound and the driving sound are mixed and output simultaneously can do. This allows the device 100 to reproduce the same situation as the existing driving situation by allowing the user to hear the driving sound simultaneously while listening to the radio.
