The application process of active anti-roll systems can be supported by the implementation of numerical online-optimization routines. This paper represents an approach for the online calculation of an optimization objective suitable to evaluate a vehicle's dynamic roll angle behaviour. The vehicle's roll behaviour is varied by an active-anti roll system at which the parameter plead determines systems' dynamic lead rate. The roll angle gain based objective Bφ,dyn is calculated from measurement data sets of sinusoidal sweep maneuver. During application runs, maneuver recognition automatically detects driven sweep maneuver with signal analysis in time and frequency domain. The calculation of Bφ,dyn with an online fast Fourier transformation includes averaging methods in order to reduce disturbance factors. The drive maneuver recognition confidence is increased by analysing the steering input signal's coherence. The measurement results confirm a shape of Bφ,dyn that is suitability for the layout of fast converging optimization routines due to a convexity and global minimum.
