Method for operating of stabilization system for trailer pulled by motor car, involves performing selective braking intervention by short circuit of armature winding of synchronous machine during unstable driving movement

摘要

#CMT# #/CMT# The method involves evaluating acceleration and/or speed signals of wheels of a towing vehicle and/or a vehicle trailer and an angle signal or angle ratio between the towing vehicle and the vehicle trailer, by a control device (3). An unstable driving movement e.g. rolling motion or oscillating motion, of the towing vehicle and/or the vehicle trailer is detected using the evaluated signals. Selective braking intervention is performed by a short circuit of an armature winding of a synchronous machine (2) during the unstable driving movement. #CMT#USE : #/CMT# Method for operating of a stabilization system for trailer (claimed) pulled by a vehicle i.e. motor car. #CMT#ADVANTAGE : #/CMT# The selective braking intervention is performed by the short circuit of the armature winding of the synchronous machine during the unstable driving movement of the towing vehicle and/or a vehicle trailer, thus ensuring driving stability of the trailer to maintain a stable driving behavior with reduced effort at a sensor system and the control device. The method enables avoiding over charging of a battery of the vehicle and reducing wear of brakes, so that a wear and maintenance free stabilizing system is produced. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic block diagram of a vehicle trailer. 1 : Stabilization system 2 : Synchronous machine 3 : Control device 4 : Acceleration sensor 6 : Power supply.
