Abstract

A system and a method of controlling shifting for a vehicle includes a data detector detecting data for a shift control, a road condition determiner determining a road condition based on the data, a short term driving tendency determiner determining a short term driving tendency of a driver based on the data, and a long term driving tendency determiner determining a long term driving tendency of the driver based on the short term driving tendency of the driver. An optimal driving mode determiner determines an optimal driving mode based on the road condition, the short term driving tendency of the driver, and the long term driving tendency of the driver, wherein the system controls shifting according to the optimal driving mode determined by the optimal driving mode determiner.

Claims

a data detector detecting data for a shifting control;

a road condition determiner determining a road condition based on the data;

a short term driving tendency determiner determining a short term driving tendency of a driver based on the data;

a long term driving tendency determiner determining a long term driving tendency of the driver based on the short term driving tendency of the driver; and

an optimal driving mode determiner determining an optimal driving mode based on the road condition, the short term driving tendency of the driver, and the long term driving tendency of the driver,

wherein the system controls shifting according to the optimal driving mode determined by the optimal driving mode determiner.

2. The system of claim 1, wherein the road condition determiner comprises:

a road state determiner determining a road state of a snowy road or a slippery road;

a road shape determiner determining a road shape of a curved road or an inclined road; and

a road congestion determiner determining a degree of congestion the road.

3. The system of claim 1, wherein the optimal driving mode determiner determines in order the short term driving tendency of the driver, and the long term driving tendency of the driver.

4. The system of claim 1, wherein the optimal driving mode determiner gives top priority to the road condition and gives the same level of priority to the short term driving tendency of the driver and the long term driving tendency of the driver.

5. The system of claim 2, wherein the optimal driving mode determiner controls shifting according to the long term driving tendency of the driver, and

wherein the optimal driving mode determiner determines a driving mode according to a specific road state as the optimal driving mode if the road state is the specific road state.

6. The system of claim 2, wherein the optimal driving mode determiner controls shifting according to the long term driving tendency of the driver, and

wherein the optimal driving mode determiner determines a driving mode according to a specific road shape as the optimal driving mode if the road shape is the specific road shape.

7. The system of claim 2, wherein the optimal driving mode determiner controls shifting according to the long term driving tendency of the driver, and

wherein the optimal driving mode determiner determines a driving mode according to a congested road as the optimal driving mode if the road is congested.

8. The system of claim 1, wherein the optimal driving mode determiner controls shifting according to the long term driving tendency of the driver, and

wherein the optimal driving mode determiner determines a driving mode according to the short term driving tendency of the driver as the optimal driving mode if the road condition determiner does not detect a specific road condition, and a difference between the short term driving tendency of the driver and the long term driving tendency of the driver is larger than a predetermined value.

9. The system of claim 1, wherein the optimal driving mode determiner controls shifting according to the long term driving tendency of the driver, and

wherein the optimal driving mode determiner determines the optimal driving mode by considering a short term driving tendency factor of the driver and a long term driving tendency factor of the driver if the road condition determiner does not detect a specific road condition.

10. The system of claim 1, wherein the shifting control comprises a change of a shift pattern, a change of engaging feeling to a target shift-speed, a change of an engine torque map, and a change of an engine torque filter.

11. A method of controlling shifting for a vehicle comprising:

detecting data for a shifting control;

determining whether a road state is a specific road state based on the data;

determining, if the road state is not the specific road state, whether a road shape is a specific road shape based on the data;

determining, if the road shape is not the specific road shape, whether the road is congested based on the data;

determining, if the road is not congested, whether a difference between a short term driving tendency and a long term driving tendency of a driver is larger than a predetermined value; and

controlling shifting according to the long term driving tendency of the driver if the difference between the short term driving tendency and the long term driving tendency of the driver is not larger than the predetermined value.

12. The method of claim 11, further comprising:

determining a driving mode according to the specific road state if the road state is the specific road state; and

controlling shifting according to the determined driving mode.

13. The method of claim 11, further comprising:

determining a driving mode according to the specific road shape if the road shape is the specific road shape; and
