Abstract

A vehicle includes a vehicle interface unit, an output of which is controlled according to user manipulation. A vehicle information acquisition unit is configured to acquire information about a vehicle state and an output of the vehicle interface unit in the vehicle state. A storage is configured to store the acquired information about the vehicle state and the output of the vehicle interface unit in the vehicle state. A model generation unit is configured to generate a user preference model using the stored information about the vehicle state and the output of the vehicle interface unit in the vehicle state. A controller is configured to control the output of the vehicle interface unit based on the user preference model.

Claims

1. A vehicle comprising:

a vehicle interface unit, an output of which is controlled according to user manipulation;

a storage configured to store information about a vehicle state and the output of the vehicle interface unit in the vehicle state;

a model generation unit configured to generate a first model to indicate a correlation between the vehicle state and the output of the vehicle interface unit as a conditional probability and a second model to determine the output of the vehicle interface unit corresponding to a current vehicle state using a rule defined by a vehicle state condition and an output of the vehicle interface unit, in which the first model and the second model are included in a user preference model; and

a controller configured to control the output of the vehicle interface unit based on the user preference model.

2. The vehicle according to claim 1, where the storage stores the information about the vehicle state and the output of the vehicle interface unit in the vehicle state every first update cycle.

3. The vehicle according to claim 2, wherein the first updated cycle is set or changed by a user.

4. The vehicle according to claim 2, wherein the storage erases the previous information stored in the storage when a used capacity of the storage exceeds a storage threshold value.

5. The vehicle according to claim 1, wherein the model generation unit generates the first model by calculating the conditional probability of the output of the vehicle interface unit for each vehicle state based on the stored information about the vehicle state and the output of the vehicle interface unit in the vehicle state.

6. The vehicle according to claim 5, wherein the model generation unit updates the first model by calculating the conditional probability every second updated cycle.

7. The vehicle according to claim 6, wherein the second updated cycle is equal to or greater than the first updated cycle.

8. The vehicle according to claim 1, wherein the model generation unit extracts a vehicle state having the conditional probability equal to or greater than a probability threshold value and the output of the vehicle interface unit corresponding to the vehicle state from the first model, and sets the extracted vehicle state as the vehicle state condition to define the rule number and sets the extracted output of the vehicle interface unit as a display result to define the rule.

9. The vehicle according to claim 8, wherein the controller determines the current vehicle state and searches for the rule of the generated second model, in which the current vehicle state is set as the vehicle state condition.

10. The vehicle according to claim 9, wherein the controller controls the output of the vehicle interface unit according to the rule in which the current vehicle state is set as the vehicle state condition, when the rule is found.

11. The vehicle according to claim 10, wherein the model generation unit determines whether the output of the vehicle interface unit is changed within a threshold time after the output of the vehicle interface unit is controlled.

12. The vehicle according to claim 11, wherein the model generation unit updates a success rate of the rule based on a determination result of whether or not the output of the vehicle interface unit is changed.

13. The vehicle according to claim 12, wherein the model generation unit increases the success rate of the rule number if the output of the vehicle interface unit is not changed for the threshold time after the output of the vehicle interface unit is controlled.

14. The vehicle according to claim 13, wherein the model generation unit reduces the success rate of the rule if the output of the vehicle interface unit is changed within the threshold time after the second output of the vehicle interface unit is controlled.

15. The vehicle according to claim 14, wherein the model generation unit erases a rule having a success rate dropped to be equal to or less than a success rate threshold value, and initializes the conditional probability corresponding to the erased rule.

16. The vehicle according to claim 1, wherein the vehicle interface unit comprises at least one of an audio video navigation (AVN) device, a cluster, a head up display (HUD), a lighting device to control lighting inside the vehicle, and a temperature control device to control temperature inside the vehicle.
