The maximum rate change of direction for a vehicle; a sidewise movement of a vehicle in turning; Movement of a vehicle in another direction than that in which it is headed; sidewise motion produced when centrifugal force exceeds traction force. Often the result of overreaction or exceeding the critical speed. Sometimes revealed by tire marks on the roadway.
The lateral acceleration rate at which a vehicle will begin to yaw.
The physical mark on the roadway caused by the rotating tires of a vehicle during a maximum rate change of direction (turn). Yaw marks are also called scuff marks.
(r) The angular velocity about the z-axis.
YAWING MOMENT COEFFICIENT
(C M z) is based on the yawing moment deriving from the distribution of aerodynamic forces acting on the vehicle.
