Patent number: 8046147Abstract: When swaying motions of a trailer or semi-trailer of a car-trailer combination are encountered, input signals which are taken into consideration to calculate a reference signal frequently include also oscillation components, due to which driving dynamics control for stabilization of the car-trailer combination can become very unreliable. To enhance the reliability of driving dynamics control of this type, a method is disclosed in which an input signal (Y) is sensed that includes signal oscillations which are due to a swaying motion of the trailer or semi-trailer and are superimposed on a base component (YBasis) of the input signal (Y). A reference signal is calculated from the input signal (Y), in which case the calculation is executed in such a way that the reference signal by approximation corresponds to a reference signal which is determined from the base component (YBasis) of the input signal (Y).Type: GrantFiled: November 16, 2006Date of Patent: October 25, 2011Assignee: Continental Teves AG & Co.

Patent number: 7860623Abstract: A process for increasing the stability of a vehicle upon acceleration on a roadway with a non-homogenous coefficient of friction, whereby a drive wheel is acted on by a braking force on a side with a low coefficient of friction by means of a drive slip regulation. A value (pASR) is determined which corresponds to the braking force (FB,ASR) set by the drive slip regulation (ASR). The value determined (pASR) is used for the determination of a disrupting yaw momentum (MZ), and a control portion (??Z) of a supplemental steering angle (??) is determined in dependence on the disrupting yaw momentum (MZ). An apparatus for the implementation of the process is also provided.Type: GrantFiled: March 15, 2005Date of Patent: December 28, 2010Assignee: Continental Teves AG & Co. oHGInventors: Urs Bauer, Georg Roll, Schahrad Schafiyha, Stephan Capellaro, Michael Gille, Matthias Muntu
