Abstract

A device for controlling shift in a vehicle may include a data detector configured to detect data for a shift control and a controller configured to determine a short-term driving tendency of a driver using the data, determine a long-term driving tendency of the driver using the short-term driving tendency of the driver, and control shift in the vehicle in consideration of a running mode of the vehicle and the long-term driving tendency which are determined from the data.

Claims

1. A device for controlling shift in a vehicle comprising:

a data detector configured to detect data for shift control; and

a controller configured to determine a short-term driving tendency of a driver using the data, determine a long-term driving tendency of the driver using the short-term driving tendency of the driver, and control shift in the vehicle in consideration of a running mode of the vehicle and the long-term driving tendency which are determined from the data.

2. The device of claim 1, wherein the controller calculates a short-term driving tendency index using the data, and determines the short-term driving tendency that is divided in a plurality of sections in accordance with a value of the short-term driving tendency index.

3. The device of claim 2, wherein the controller calculates a long-term driving tendency index using the short-term driving tendency, and determines the long-term driving tendency that is divided in a plurality of sections in accordance with a value of the long-term driving tendency index.

4. The device of claim 3, wherein the controller determines whether the running mode is a first mode.

5. The device of claim 4, wherein when it is determined that the running mode is the first mode, the controller determines whether the long-term driving tendency index of the driver is equal to or greater than a predetermined reference value.

6. The device of claim 5, wherein when it is determined that the long-term driving tendency index of the driver is equal to or greater than the predetermined reference value, the controller changes the running mode to a second mode.

7. The device of claim 5, wherein when it is determined that the long-term driving tendency index of the driver is less than the predetermined reference value, the controller maintains the running mode as the first mode.

8. The device of claim 1, wherein the data includes at least one of a speed of the vehicle, acceleration of the vehicle, a shift-speed, a steering angle of the vehicle, and a distance between the driver'"'"'s vehicle and a forward vehicle.

9. A method for controlling shift in a vehicle comprising:

detecting data for shift control;

determining a short-term driving tendency of a driver using the data;

determining a long-term driving tendency of the driver using the short-term driving tendency of the driver;

determining a running mode of the vehicle from the data; and

controlling shift in the vehicle in consideration of the long-term driving tendency and the running mode of the vehicle.

10. The method of claim 9, wherein the determining of the short-term driving tendency of the driver includes:

calculating a short-term driving tendency index using the data; and

determining the short-term driving tendency that is divided in a plurality of sections in accordance with a value of the short-term driving tendency index.

11. The method of claim 10, wherein:

the determining of the long-term driving tendency of the driver includes calculating a long-term driving tendency index using the short-term driving tendency, and determining the long-term driving tendency that is divided in plural numbers in accordance with a value of the long-term driving tendency index.

12. The method of claim 11, wherein the controlling of the shift in the vehicle includes determining whether the running mode is a first mode.

13. The method of claim 12, wherein the controlling of the shift in the vehicle further includes determining whether the long-term driving tendency index of the driver is equal to or greater than a predetermined reference value when it is determined that the running mode is the first mode.

14. The method of claim 13, wherein the controlling of the shift in the vehicle further includes changing the running mode to a second mode when it is determined that the long-term driving tendency index of the driver is equal to or greater than the predetermined reference value.

15. The method of claim 13, wherein the controlling of the shift in the vehicle further includes maintaining the running mode as the first mode when it is determined that the long-term driving tendency index of the driver is less than the predetermined reference value.

16. The method of claim 9, wherein the data includes at least one of a speed of the vehicle, acceleration of the vehicle, a shift-speed, a steering angle of the vehicle, and a distance between the driver'"'"'s vehicle and a forward vehicle.
