A vehicle control apparatus comprising, a center of gravity six-component calculation unit for calculating a center of gravity six-component as vehicle motion targets based on a driver input, a tire three-component calculation unit for calculating a tire three-component of four wheels of a vehicle based on the center of gravity six-component, a vehicle control unit for performing vehicle control by the vehicle control, actuator group based on the tire three-component of the four wheels, and wherein the tire three-component calculation unit calculates the tire three-component of the four wheels from the center of gravity six-component by a coordinate transformation without repetition, which is normalization with the driving stiffness of each wheel and the cornering stiffness of each wheel, when the number of control requests in the vehicle control is less than degrees of freedom of the vehicle control actuator group.

There is provided a method for activating warning lights in a vehicle, the method comprising: determining a yaw rate of the vehicle; determining a sideslip angle of the vehicle; comparing the yaw rate to a predetermined yaw rate threshold value; comparing the sideslip angle to a predetermined sideslip angle threshold value; and f the yaw rate exceeds the predetermined yaw rate value; if the sideslip angle exceeds the predetermined sideslip angle value; and if it is determined that the vehicle reaches a standstill within a predetermined time after the yaw rate and sideslip values have been exceeded, activating warning lights of the vehicle. There is also provided a system configured to perform the above described method.

Coordinates of a point, representing a current pair of states of a vehicle, can be determined to be outside of a first curve. An interior of the first curve, representing a first region of operation of the vehicle, can be characterized by values of forces produced by tires being less than a saturation force. A distance between the point and a second curve can be determined. An interior of the second curve, representing a second region of operation of the vehicle, can be characterized by an ability of an operation of a control system to cause the vehicle to change from being operated in the current pair of states to being operated in the first region of operation. A manner in which the vehicle changes from being operated in the current pair of states to being operated in a different pair of states can be controlled based on the distance.
