Classification: CPC B | IPC B

Claim 0:
1. An apparatus for improving turning performance of a vehicle, the apparatus comprising:
at least one sensor configured to obtain vehicle information; and
a processor configured to execute algorithm steps stored in a memory, the processor configured to:
detect a turning situation based on the vehicle information,
calculate a required driving force to be implemented in the vehicle for a turning motion based on an accelerator pedal signal manipulated by a driver,
estimate a limited driving force applicable to a drive wheel based on a normal force and a lateral force, the processor being configured to i) calculate a radius of the Kamm's circle by multiplying the normal force by a friction coefficient and ii) determine 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
control and apply a braking force corresponding to a difference between the required driving force and the limited driving force to an electric motor to inhibit a wheel slip when the required driving force is greater than the limited driving force.
