Problems solved by technology

However, no analysis and / or monitoring of disturbance frequencies and / or vibration patterns takes place here, so that the effectiveness of the compensation is only representative of the respective vehicle and is only subjectively perceptible by the driver, but cannot be transmitted to other vehicles.

Embodiment Construction

[0032] attached Figure 1a and 1b In a simplified illustration, an exemplary vehicle 10 , which is designed as a motor vehicle, is shown with a plurality of wheels 36 and a steering system 38 . Steering system 38 is operatively connected to wheels 36 and is provided for influencing the direction of travel of vehicle 10 .

[0033] Steering system 38 includes a steering device. The steering device has a steering gear 40 . The steering transmission mechanism 40 is configured as a rack-type steering transmission mechanism. The steering gear 40 includes a steering pinion 42 and a rack 44 mechanically coupled to the steering pinion 42 . The steering gear 40 is operatively connected to at least two of the wheels 36 , in particular the two front wheels of the vehicle 10 . The steering gear 40 is provided to bring about a pivoting and / or rotational movement of the wheels 36 . Steering gear 40 is provided to convert a steering preset into a steering movement of wheels 36 . In prin...

Abstract

The invention is based on a method for analysing and / or at least partially compensating steering wheel torsional vibrations, particularly during operation of a steering device in a vehicle (10, 20), wherein at least one sensing signal (12) is acquired and at least one interference characteristic variable (14) which is correlated to the steering wheel torsional vibration is extracted from the sensing signal (12). It is proposed that during a monitoring time interval a change over time in the interference characteristic variable (14) and a change over time in a wheel frequency (16) which is correlated to a current wheel rotational speed characteristic variable is monitored and the changes are combined in order to analyse and / or to at least partially compensate steering wheel torsional vibrations to form a common evaluation dataset (18, 20).

Description

technical field [0001] The invention is based on a method for analyzing and / or at least partially compensating rotational vibrations of a steering wheel according to the preamble of claim 1 . [0002] Furthermore, the invention relates to a steering device according to claim 10 , a system according to claim 11 and a control unit according to claim 12 . Background technique [0003] Methods for analyzing and / or compensating rotational vibrations of a steering wheel are known from the prior art. [0004] In this context, for example, it is known to use a transfer function which calculates an effective reaction torque based on the torque signal and supplies this reaction torque to the electric motor of the steering system for the compensation of steering wheel rotational vibrations. In this case, the transfer function is typically determined iteratively with the aid of individual vehicles of a particular vehicle variant and stored in the controller during the manufacture of th...
