Method and engine control for suppressing vibration of the drive train in a motor vehicle |
摘要 |
A method and an engine control for suppressing vibration in the drive train of a motor vehicle include detecting a variable being dependent on a speed of an engine, deriving and evaluating a gradient from the variable, reducing a torque of the engine by varying an ignition angle if impermissible vibration is detected, and controlling the torque reduction as a function of an upper and a lower threshold value for the gradient. An ignition intervention is carried out for reducing the engine torque if the gradient is below the lower threshold. The ignition intervention is cancelled if the gradient exceeds the upper threshold value. First lower threshold values are stored in a first performance graph, and second higher threshold values are stored in a second performance graph to which a switchover is made after a first tripping of an anti-bucking function.
