A running stability control device for a vehicle capable of controlling a
steering angle of steered vehicle wheels independently of a steering
operation by a driver, and a driving/braking force applied to each
vehicle wheel computes a target turn running control quantity of the
vehicle, and shares the target turn running control quantity into a first
part for the steering angle control and a second part for the
driving/braking force control according to a sharing ratio, wherein the
sharing ratio is variably changed according to a running condition of the
vehicle relative to a road.
