Abstract
A method for estimating a transverse acceleration at an axle of a trailer/semitrailer of a vehicle combination including the step of measuring or estimating the yaw velocity &ohgr;Z of the towing vehicle, measuring or estimating the forward velocity vxZ of the towing vehicle, measuring or estimating an articulation angle &Dgr;&PSgr; between the towing vehicle and the trailer/semitrailer, particularly between a longitudinal axis xZ of the towing vehicle and a longitudinal axis zA of the trailer/semitrailer, and computationally correlating (or performing a relational operation on) the values &ohgr;Z, vxZ and &Dgr;&PSgr; to obtain an estimated value of the transverse acceleration ayAA at the axle of the semitrailer/trailer.
