Method and device for considering the driver's steering response in stabilizing a vehicle-trailer combination
First Claim
1. A device for damping the snaking motions of a trailer towed by a road vehicle, comprising:
- snaking motion detection means (101) by which the trailer'"'"'s snaking motion and the motions'"'"'s intensity are detected based on a variable (vGiF-vGiSoAck) into which there enters at least one variable (vGiF) describing the transverse vehicle dynamics, snaking damping means which, when an intensity limiting value is exceeded by the intensity of the snaking motion, damp the snaking motion on the basis of driver-independent braking interventions (105) in the road vehicle or a driver-independent throttling of the engine torque (104), and steering angle analyzing means (201) which determine at least one parameter (KoLw) from the shape of the curve of the steering angle (Lw) over time, and wherein the intensity limiting value, in response to whose exceeding by the intensity of the snaking motion, the snaking motion is damped, is a function of the parameter (KoLw) determined.

Abstract
A device for damping the snaking motion of a trailer towed by a road vehicle is described, including snaking motion detection means by which the trailer'"'"'s snaking motion and the motion'"'"'s intensity are detected based on a variable into which there enters at least one variable describing the transverse vehicle dynamics, and snaking damping means which, when an intensity limiting value is exceeded by the intensity of the snaking motion, damp the snaking motion on the basis of driver-independent braking interventions in the road vehicle and/or a driver-independent throttling of the engine torque. The main object is characterized in that steering angle analyzing means are present which determine at least one parameter from the shape of the curve over time of the steering angle, and the intensity limiting value, in response to whose exceeding by the intensity of the snaking motion, the snaking motion is damped, is a function of the parameter determined.
