Abstract
The vehicle turning control device for a vehicle includes a first road surface frictional coefficient calculator (), a second road surface frictional coefficient calculator (), a control gain calculator (), a target yaw rate calculator (), a target yaw rate corrector (), a first braking/driving force calculator (), and a second braking/driving force calculator (). A second road surface frictional coefficient μis obtained without braking/driving forces for respective wheels () being taken into consideration, and thus has a magnitude smaller than or equal to the magnitude of a first road surface frictional coefficient μ. A braking/driving force command value calculator () calculates a braking/driving force command value from a braking/driving force (FA) and a braking/driving force (FB) which are respectively calculated with use of the first and second road surface frictional coefficients μand μ
