Electronic controllers for vehicles support a driver during dynamic manoeuvres and stabilize the vehicle with the help of systems like ESP (Electronic Stability Program) and AFS (Active Front Steering), having a significant share in avoiding accidents. Vehicles with a high centre of gravity are brought into focus on account of their tendencies to roll over due to great lateral accelerations or a build-up of the roll angle after a jerking of the steering wheel. This 'un-tripped rollover' can be avoided with active safety systems, yet the support of the known controllers is not always enough to prevent the tipping over. Prerequisite for triggering particular measures of rollover prevention is the reliable discrimination of the rollover event. Possible anti-rollover measures are appropriate interventions with active brake, active steering or with active suspension. At the Robert Bosch GmbH, a study had accomplished the prevention of un-tripped rollover, providing a controller approach to discriminate the rollover situation and to calculate the set points for the stabilizing interventions. Active steering and active brake interventions stabilize the vehicle accordingly, so that the driver can cope with the rollover risk - at utmost driving stability and comfortable handling of the vehicle. This contribution focuses on the actuating dynamics of the AFS and their influence on the valuation criteria vehicle stabilisation, agility and comfort with respect to the rollover mitigation (ROM) function. The ROM function itself was already published. Naturally, the trajectory of the setting ESP-AFSfast (black, dash-dotted) shows the best result. The curve of the trace already changes its direction during 'Counter Steer', significantly different from the settings ESP and ESP-AFSslow, and even enhanced compared to ESP-AFSmedium. The vehicle responds best to the steering input and travels the lowest lateral deviation after 'Counter Steer'. A maximum roll angle of PhiMax = 5.7 deg was measured. The observations during the manoeuvres confirmed, that with fast steering interventions, even the laden vehicle was never in danger to tip over, but accomplished the 'Fishhook' in a stable and comfortable way, with the appropriate deceleration and without confusing oscillations.
