Abstract

A method and a system for controlling vehicle shifting is configured to change shift patterns by reflecting a driver'"'"'s shifting habits. The method may include running the vehicle according to a first shift pattern, detecting control parameters, determining whether the detected control parameters satisfies a first shift pattern conversion condition, and running the vehicle according to a second shift pattern when the first shift pattern conversion condition is satisfied.

Claims

1. A method for controlling vehicle shifting, comprising:

running the vehicle according to a first shift pattern;

detecting control parameters;

determining whether the detected control parameters satisfies a first shift pattern conversion condition; and

running the vehicle according to a second shift pattern when the first shift pattern conversion condition is satisfied.

2. The method of claim 1, wherein the first shift pattern conversion condition is satisfied when a position value of an accelerator pedal is larger than or equal to a predetermined position value, and a position change of the accelerator pedal is larger than or equal to a predetermined position change.

3. The method of claim 1, further comprising:

detecting the control parameters during running the vehicle according to the second shift pattern;

determining whether the detected control parameter satisfies a second shift pattern conversion condition; and

running the vehicle according to the first shift pattern when the second shift pattern conversion condition is satisfied.

4. The method of claim 3, wherein the second shift pattern conversion condition is satisfied when the vehicle is stopped or a position of a shift lever is P, R, or N range.

5. A system for controlling vehicle shifting, comprising:

an accelerator pedal position sensor detecting a position of an accelerator pedal;

a shift lever position sensor detecting a position of a shift lever;

a vehicle speed sensor detecting a vehicle speed; and

a control portion operatively connected to the accelerator pedal position sensor, the shift lever position sensor, and the vehicle speed sensor, the control unit controlling vehicle shifting;

wherein the control portion runs the vehicle according to a first shift pattern at an initial state, and runs the vehicle according to a second shift pattern when a first shift pattern conversion condition is satisfied.

6. The system of claim 5, wherein the first shift pattern conversion condition is satisfied when a position value of an accelerator pedal is larger than or equal to a predetermined position value, and a position change of the accelerator pedal is larger than or equal to a predetermined position change.

7. The system of claim 5, wherein the control portion runs the vehicle according to the first shift pattern when a second shift pattern conversion condition is satisfied during running the vehicle according to the second shift pattern.

8. The system of claim 7, wherein the second shift pattern conversion condition is satisfied when the vehicle is stopped or a position of a shift lever is P, R, or N range.
