A turning control apparatus for a vehicle that improves turning ability while avoiding degradation of acceleration ability is provided. The turning control apparatus comprises: a driving torque controller () for adjusting driving torque between a left and right wheels (L andR); a unit () for calculating a necessary yaw momentum value indicating degree of necessary yaw momentum for the turning of the vehicle; and a clipping unit () for clipping the necessary yaw momentum value as a target yaw momentum at a maximum yaw momentum value, which is defined according to difference between rotation speeds of inside and outside wheels, if the necessary yaw momentum value is over the maximum yaw momentum value. The controller adjusts driving torque of the left and right wheels to generate target yaw momentum at the vehicle corresponding to the target yaw momentum value obtained by the clipping unit.

Turning control apparatus for vehicle

A turning control apparatus for a vehicle to improve turning ability and to avoid degradation of acceleration ability is provided. The turning control apparatus comprises a first yaw controller for adjusting at least one of driving torque of a left wheel and a right wheel; a second yaw controller for adjusting a speeds difference between a front wheel and a rear wheel; and an integrated yaw controller for controlling yaw momentum of the vehicle by managing the first and second yaw controller, wherein when the yaw of the vehicle should be reduced, the integrated yaw controller controls the first yaw controller so as to decrease the driving torque of a inside wheel, which is one of the right and left wheel and is near to a center axis of turning, and the second yaw controller so as to decrease the speeds difference between the front and rear wheel.

The turning control apparatus for a vehicle has a driving torque controlling mechanism adjusting driving torque of left and right wheels. The apparatus includes a maximum-yaw momentum value calculating means having means for estimating an outside-wheel gripping capacity, which is capacity of adhesive friction between the outside-wheel and a road surface, and an inside-wheel gripping capacity, which is capacity of adhesive friction between the inside-wheel and the road surface, and means for calculating a torque adjustment limiting value indicating an adjustment amount of driving torque by the driving torque controlling mechanism so that the adjustment amount does not exceed the gripping capacity. The maximum-yaw momentum value calculating means sets the maximum-yaw momentum value indicating possible yaw momentum, which is estimated if the driving torque is adjusted along with the torque-adjustment-limit value calculated by the torque adjustment limiting value calculating means.
