Stabilization of articulated trains (ESP)

The invention relates to a method and a system for preventing vehicle instabilities for a vehicle composite consisting of a towing vehicle (2) and a drawbar trailer (4), wherein the towing vehicle (2), a sensor (101, 102, 121, 122, 20, 22, 24 ) for detecting differences between a driver's desired and an actual driving movement, captured in response to a (by the sensors 101, 102, 121, 122, 20, 22, 24) the difference between the driver's desired and the actual driving movement at least in the towing vehicle (2) a wheel-individual impingement is provided with braking forces to produce a yaw moment opposes to a yawing moment due to between the driver's desired direction and the actual vehicle movement, and wherein, when differences are detected, additional braking is provided by at least the trailer rear axle (16).
