Abstract
A method of controlling a vehicle includes determining a lateral tire force, a front lateral tire force, a rear lateral tire force, and determining a linear sideslip angle from the front lateral tire force and the rear lateral tire force. The method further includes determining a linear lateral velocity in response to the linear sideslip angle and controlling the vehicle in response to the linear sideslip angle.
