摘要： A steering control apparatus obtains a steered amount by which a steered wheel is steered based on a left-and-right braking force difference control amount, a vehicle state control amount, and a steering control amount. The apparatus changes the magnitude of the braking force difference control amount and the magnitude of the vehicle state control amount according to a vehicle speed or to time elapsed from when braking started to be applied to the left and right wheels. Accordingly, the vehicle driving on μ-split road is prevented from being deflected toward a side of higher friction coefficient due to the left-and-right braking force difference when the braking is applied.

摘要： An angular velocity detection device is provided for detecting an angular velocity about a single axis tilted in a longitudinal direction of a vehicle to a normal axis thereof. An actual motion state variable of the vehicle is calculated on the basis of the detected angular velocity. At least one of the braking force and driving force applied to a vehicle is controlled to stabilize a yawing motion and a rolling motion of the vehicle, on the basis of a motion state variable deviation between a desired motion state variable and the actual motion state variable, e.g., a deviation between a yaw velocity and a roll velocity of the vehicle.

摘要： A steering device is provided for controlling steering torque applied to a steering wheel of a vehicle. A braking device is provided for controlling longitudinal force applied to each wheel, and a control device is provided for performing at least one of an anti-skid control and a traction control. It is observed whether the control device is performing the control on a split road surface. The steering torque is controlled on the basis of a difference of longitudinal force applied to the right and left wheels, and a turning state amount deviation between a turning state amount and a desired amount thereof. The desired amount of turning state is calculated, on the basis of the turning state of the vehicle obtained when one of the anti-skid control and the traction control is performed on the split road surface.
