Document Type and Number:
Japanese Patent JP2001511732
Kind Code:
A
Abstract:
The speed variation of the driven wheels is analyzed in a method of recognizing critical drive train oscillations which require countermeasures during an (ABS) controlled brake maneuver. The occurrence of oscillations having a frequency typical of drive train oscillations is established. When oscillations with this frequency occur, the duration of the oscillating process is established on each individual wheel, or the number of the successive oscillations or semi-wave oscillations is counted. When a predetermined counter reading is reached, an oscillation recognition is indicated if, at that time, the vehicle acceleration is above a predetermined limit value and if oscillation recognition has not yet been triggered on the other driven wheel. To dampen the oscillations, switch-over to a special control is effected for a defined interval. The commencement of the special control prevents braking pressure reduction, the pressure is maintained constant, or at most a delayed pressure increase is allowed.
