Claim 9:
10. A method for improving turning performance of a vehicle, the method comprising:
detecting, by a processor, a turning situation based on vehicle information obtained from at least one sensor;
calculating, by the processor, a required driving force to be implemented in the vehicle for a turning motion based on an accelerator pedal signal manipulated by a driver;
estimating, by the processor, a normal force and a lateral force applied to a tire based on the vehicle information;
estimating, by the processor, a limited driving force using the estimated normal force and the estimated lateral force, including i) calculating a radius of the Kamm's circle by multiplying the normal force by a friction coefficient and ii) determining the limited driving force such that a sum of the lateral force and the limited driving force is the radius of the Kamm's circle; and
controlling and applying, by the processor, a braking force corresponding to a difference between the required driving force and the limited driving force to a motor when the required driving force is greater than the limited driving force.
