METHOD FOR DETERMINING CONTROLLED VARIABLE OF COORDINATE CONTROL ON SPLIT ROAD SURFACE USING DECELERATION OF VEHICLE
First Claim
1. A method of determining a controlled variable of coordinate control on a split road surface using deceleration of a vehicle, the method comprising:
- calculating a deceleration of the vehicle by differentiating a reference velocity (Vref) calculated by an electronic stability control system;
calculating an override angle of an active front-wheel steering system by multiplying the deceleration of the vehicle by a control gain;
determining a control direction of the vehicle; and
obtaining a controlled variable for a steering angle by multiplying the calculated override angle of the active front-wheel steering system by the determined control direction of the vehicle.

Abstract
Disclosed herein is a method of determining a controlled variable of coordinate control on a split road surface using deceleration of a vehicle. The method includes calculating deceleration of the vehicle by differentiating a reference velocity (Vref) calculated by an electronic stability control system, calculating an override angle of an active front-wheel steering system by multiplying the deceleration of the vehicle by a control gain, determining a control direction of the vehicle, and obtaining a controlled variable for a steering angle by multiplying the calculated override angle of the active front-wheel steering system by the determined control direction of the vehicle. The method enables the vehicle to maintain a straight behavior without driver'"'"'s steering intervention when the driver brakes on the split road surface
