Verfahren zum Dämpfen von Antriebsstrangschwingungen

摘要

The invention relates to a process for damping critical wheel or drive train vibrations requiring countermeasures during an ABS-controlled brake manoeuver. The speed characteristic of the wheels being driven is analyzed and upon recognition of critical wheel vibrations is switched over to a special control for a set period of time. The intervention of the special control prevents a reduction of brake pressure, keeps pressure constant or at best allows delayed pressure build-up. In the case of vibrations with a frequency which is typical for wheel vibrations, the number of successive vibrations or semi-vibrations of each individual wheel is counted. When a pre-set number is reached, vibration recognition is indicated (BY_DRIVE_REC=1) if at that time the vehicle acceleration is above a set limit value and if there has not yet been vibration recognition on the other wheel being driven.
