Abstract

An automatic full-turn control method for MDPS includes determining if automatic Full-Turn conditions for the MDPS are satisfied, full turning the MDPS when the automatic Full-Turn conditions for the MDPS are satisfied, determining if automatic Full-Turn releasing conditions for the MDPS are satisfied and releasing the Full-Turn of the MDPS when the releasing conditions for the MDPS are satisfied.

Claims

1. An automatic full-turn control method for Motor Driven Power Steering (MDPS) comprising:

determining if automatic Full-Turn conditions for the MDPS are satisfied;

full turning the MDPS when the automatic Full-Turn conditions for the MDPS are satisfied;

determining if automatic Full-Turn releasing conditions for the MDPS are satisfied; and

releasing the Full-Turn of the MDPS when the releasing conditions for the MDPS are satisfied.

2. The automatic full-turn control method of claim 1, wherein the determining conditions of the automatic Full-Turn conditions comprises:

determining if an operation of the MDPS is normal.

3. The automatic full-turn control method of claim 1, the determining conditions of the automatic Full-Turn conditions comprises:

determining if a MDPS Full-Turn switch is on.

4. The automatic full-turn control method of claim 3, wherein the MDPS Full-Turn switch is integrally formed with a turn-signal switch.

5. The automatic full-turn control method of claim 1, the determining conditions of the automatic Full-Turn conditions comprises:

determining if speed of a vehicle is “

0” and

an elapsed time of which the vehicle'"'"'s speed is “

0”

is over a predetermined standard time.

6. The automatic full-turn control method of claim 1, the determining conditions of the automatic Full-Turn conditions comprises:

determining if present shift range is driving range.

7. The automatic full-turn control method of claim 1, wherein the automatic Full-Turn releasing conditions are determined to be satisfied if any one of steering information including a steering angle condition, a steering angle speed condition and a steering wheel torque condition is satisfied.

8. The automatic full-turn control method of claim 1, wherein the automatic Full-Turn releasing conditions are determined to be satisfied if any one of driving information including a vehicle speed condition, a vehicle speed change condition, an engine rpm condition, an engine rpm change condition is satisfied.
