Steering and braking control is applied to avoid rollover of road vehicles. The control concept presented is composed of three feedback loops: Continuous operation steering control, emergency steering control and emergency braking control. In continuous operation the roll rate and the roll acceleration are fed back by velocity scheduled gains to the front(More)
Active safety technologies for reduction of rollover risk are dealing until now primarily with active suspension systems. In this paper a new vehicle dynamics approach is investigated, in which robust steering control is applied to avoid rollovers of vehicles with a high center of gravity. In addition to the driver's steering angle a small auxiliary(More)
Active steering is applied to robustly reduce the rollover risk of vehicles with an elevated center of gravity. An actu-ator sets an auxiliary steering angle which is mechanically added to the steering angle commanded by the driver. The control law presented, is based on feedback of the roll rate and the roll acceleration. The controller gains are scheduled(More)
In this paper for the design of a Steer-by-Wire (SbW) system a generic controller structure is proposed with bidirectional position feedback. The design goal for SbW here is to match the dynamics of an (electric/hydraulic power) steering system which may notionally be subdivided into a manual and an assistance steering part. For matching the manual steering(More)
In this paper a generic procedure for the control design of a steer-by-wire (SbW) system with a force reflecting handwheel is proposed. The design goal is to adapt the SbW performance to the performance of an almost arbitrarily given reference system. Here, in a first step the dynamics of an (electric/hydraulic power) steering shall be matched by the SbW(More)
