Abstract

An adaptive audio system for a motor vehicle is disclosed. The audio system is operable to retrieve a music item from a storage device, classify the music item in a predefined music category the basis of a determined audio profile, select a category from a plurality of predefined music categories on the basis of a current driving behavior of the driver, and output a music item included in the selected category via an output device. The driving behavior of the driver is understood to mean the mode or style in which the driver drives.

Claims

1. An audio system for a motor vehicle comprising:

an output device configured to output audio signals;

a computing unit and a software product that, when running on the computing unit instructs the computing unit to perform the following;

retrieve at least one music item from at least one storage device;

determine an audio profile for the at least one music item;

classify the at least one music item in at least one of a music categories on the basis of the determined audio profile;

determine at least one driving parameter that characterizes a current driving behavior of the driver of the motor vehicle;

classify the current driving behavior of the driver on the basis of the at least one determined parameter;

select a category from the plurality of predefined music categories on the basis of the classified current driving behavior of the driver; and

output the at least one music item included in the selected category via the output device,

wherein the software product instructs the computing unit to determine a stage profile for a stage of a journey currently being travelled by the vehicle, and wherein the selection of the category from the plurality of predefined music categories is made on the basis of the classified current driving behavior of the driver and on the basis of the determined stage profile.

2. The audio system according to claim 1, wherein the audio profile of the at least one music comprises at least one of a volume profile and a tempo profile tier the at least one music item.

3. The audio system according to claim 1, wherein the at least one driving parameter comprises at least one parameter selected from the group consisting of a speed of the vehicle, an acceleration of the vehicle, a steering angle, an accelerator pedal position, a brake pedal position and a setting of driving mode controller.

4. The audio system according to claim 1, the at least one music item is retrieved from a storage device located outside of the motor vehicle.

5. The audio system according to claim 1, wherein the output of the at least one music item begins at a predefined point in the music item.

6. The audio system according to claim 1, wherein the selection of the category from the plurality of predefined music categories is made by a user input on the basis of a user-specified assignment of at least one category of the plurality of predefined music categories to at least one behavior category of a plurality of predefined driving behavior categories.

7. The audio system according to claim 1, wherein the software product instructs the computing unit to determine a stage profile for a stage of a journey the vehicle is going to travel, and wherein the selection of the category from the plurality of predefined music categories is made on the basis of the classified current driving behavior of the driver and on the basis of the determined stage profile.

8. The audio system according to claim 1, wherein the software product instructs the computing unit to determine whether a user request to output a music item selected on the basis of the current driving behavior of the driver via the output device has been made, wherein the category is selected from the plurality of predefined music categories, and the at least one music item is output when a user request to output a music item selected on the basis of the current driving behavior of the driver via the output device has been made.

9. The audio system according to claim 8, wherein the output of the at least one music item takes place after a music item that is currently being output via the output device has ended.

10. The audio system according to claim 8, wherein the output of the at least one music item takes place immediately after the user request is confirmed.

11. A non-transitory computer-readable medium having a software product that, when running on a computing unit of an audio system in a vehicle having an output device configured to output audio signals, instructs the computing unit to perform the following:

retrieve at least one music item from at least one storage device;

determine an audio profile for the at least one music item;

classify the at least one music item in at least one of a plurality of predefined music categories on the basis of the determined audio profile;

determine at least one parameter that characterizes a current driving behavior of the driver of the motor vehicle;

classify the current driving behavior of the driver on the basis of the at least one determined parameter;

select a category from the plurality of predefined music categories on the basis of the classified current driving behavior of the driver; and

output the at least one music item included in the selected category via the output device,

wherein the software product instructs the computing unit to determine a stage profile for a stage of a the vehicle is going to travel, and the selection of the category from the plurality of predefined music categories is based on the classified current driving behavior of the driver and the determined stage profile.

12. A method for operating an adaptive audio system in a motor vehicle comprising:

retrieving at least one music item from a music storage device;

determining an audio profile for the at least one music item;

classifying the at least one music item in at least one of a plurality of predefined music categories on the basis of the audio profile;

determining at least one driving parameter characterizing a current driving behavior of the driver of the motor vehicle;

classifying the driving behavior on the basis of the at least one driving parameter;

selecting a category from the plurality of predefined music categories on the basis of the classified current driving behavior of the driver; and

outputting the at least one music item included in the selected category via an audio output device in the motor vehicle and beginning the output of the at least one music item at a predefined point in the music item.

13. The method according to claim 12 further comprising retrieving the at least one music item from a storage device located outside of the motor vehicle.

14. The method according to claim 12, further comprising selecting the category from the plurality of predefined music categories with a user input on the basis of a user-specified assignment of at least one category of the plurality of predefined music categories to at least one behavior category of a plurality of predefined driving behavior categories.

15. The method according to claim 12, further comprising determining a stage profile fur a stage of a journey currently being travelled by the vehicle, wherein the selection of the category from the plurality of predefined music categories is made on the basis of the classified current driving behavior of the driver and on the basis of the determined stage profile.

16. The method according to claim 12, further comprising determining a stage profile for a stage of a journey the vehicle is going to travel, wherein the selection of the category from the plurality of predefined music categories is made on the basis of the classified current driving behavior of the driver and on the basis of the determined stage profile.

17. The method according to claim 12, further comprising determining whether a user request to output a music item selected on the basis of the current driving behavior of the driver via the output device has been made, wherein the category is selected from the plurality of predefined music categories, and the at least one music item is output when a user request to output a music item selected on the basis of the current driving behavior of the driver via the output device has been made.
