Patent ID: 7418327

Claim:
A method for controlling a yaw rate of a vehicle by determining a steering transit angle change for an active steering device ( 10 ) of the vehicle ( 1 ) controllable by a control device ( 11 ), the method comprising the steps of; influencing driving dynamics of the vehicle ( 1 ) including the yaw rate and steering transit angle change; determining the steering transit angle change by the steps of; calculating a nominal yawing rate (φ_ 0 ) according to an initial steering transit angle preset by a driver, static wheel tread forces, and an actual speed of the vehicle without determining longitudinal forces which affect the driving dynamics of the vehicle; determining a desired steering transit angle by applying the nominal yawing rate (φ_ 0 ) to a dynamic driving state of the vehicle determined according to the actual speed of the vehicle, a longitudinal dynamic wheel tread forces affecting the driving dynamics of the vehicle and the initial steering transit angle; subtracting the desired steering transit angle from the initial steering transit angle to obtain the steering transit angle change; and superimposing the steering transit angle change on the steering transit angle (δ_ 0 ) preset by the driver so that an actual yawing rate is reduced towards the nominal yawing rate (φ_ 0 ).
