A method for the operation of a controllable steering system in a motor vehicle, a corresponding computer program and to a corresponding control unit

A method for the operation of a controllable steering system in a motor vehicle wherein a functional behavior of a controllable steering system due to an interaction of the driver with a man-machine interface (HMI) is influenced and the driver's interaction of a, as to affect a change to at least a functional behavior input value (Vx, .DELTA.S) effect of the controllable steering system and the change of the input parameter (Vx, .DELTA.S) by means of a parameterized mathematical algorithm (ALGO) is made, where the driver's interaction causes the influence on the functional behavior due to a variation of a basic family of characteristics (CC) characterized in that the change of the basic characteristic field (CC) by means of a parameterized mathematical algorithm (ALGO) is made.
