Abstract:
The vehicle turning control device for a vehicle includes a first road surface frictional coefficient calculator (22), a second road surface frictional coefficient calculator (25), a control gain calculator (23), a target yaw rate calculator (21), a target yaw rate corrector (27), a first braking/driving force calculator (24), and a second braking/driving force calculator (28). A second road surface frictional coefficient μ2 is obtained without braking/driving forces for respective wheels (2) being taken into consideration, and thus has a magnitude smaller than or equal to the magnitude of a first road surface frictional coefficient μ1. A braking/driving force command value calculator (29) 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 μ1 and μ2.
