Abstract
A method and system for preventing rollover of a vehicle train comprising a tractor vehicle and a trailer vehicle. A control system is provided in the tractor vehicle which automatically initiates actuation of the braking system of the tractor vehicle and/or of the trailer vehicle if a danger of rollover of the vehicle train is recognized. A data signal from which it is possible to deduce the speed of at least one wheel of the trailer vehicle at the inside of a curve is transmitted from the trailer vehicle to the control system. The control system uses the data signal to recognize the danger of rollover of the vehicle train.
