Abstract

Methods and systems for controlling a vehicle are provided which can include advantages of controlling corresponding to lateral wind frequency. Because the vehicle is controlled on the basis of frequency areas and a force of a lateral wind, driving stability of the vehicle and driver comfort can be enhanced.

Claims

1. A method for controlling a vehicle movement, comprising:

detecting at least one parameter, including a frequency of a lateral wind acting on a vehicle, and wherein the at least one parameter comprises a force of the lateral wind;

applying one or more predetermined modes corresponding to the frequency of the lateral wind;

operating a vehicle dynamics control system (VDCS) or an electronic power steering (EPS) apparatus corresponding to the one or more predetermined modes;

determining if the force of the lateral wind is more than a first predetermined value;

determining if the force of the lateral wind is more than a second predetermined value, which is more than the first predetermined value, in a case that the detected force of the lateral wind is more than the first predetermined value; and

operating an impact mode which operates only the VDCS in a case where the detected force of the lateral wind is more than the second predetermined value.

2. The method of claim 1,

wherein, in a case where the detected force of the lateral wind is less than the first predetermined value, the detecting of the at least one parameter is performed again.

3. The method of claim 1,

wherein, in a case where the detected force of the lateral wind is less than the second predetermined value, determining the frequency of the lateral wind.

4. The method of claim 1,

wherein the predetermined modes comprise:

a static mode operating the vehicle dynamics control system in a case where the frequency is less than 0.5 Hz;

a non-static mode operating the vehicle dynamics control system and the electronic power steering apparatus simultaneously in a case where the frequency is from 0.5 to 2.0 Hz; and

a high-frequency mode operating the electronic power steering apparatus in a case where the frequency is more than 2.0 Hz.

5. The method of claim 4,

further comprising displaying on a display device a mode to be applied just before the predetermined mode is applied.
