Abstract

A method for the active roll stabilization of a vehicle (50) by way of a roll stabilizer (30). The roll stabilizer (30) includes a stabilizer rod (32), a stabilizer housing (34) and a stabilizer motor (36), arranged inside the stabilizer housing (34), so that a first end of the stabilizer rod (32) is connected at to a wheel (52) of the vehicle and at a second end thereof is mounted to be rotated by way of the stabilizer motor (36). The method including the steps of obtaining a first set-point value of a rod torque of the stabilizer rod (32); obtaining a second set-point value of a motor rotation angle of the stabilizer motor (36); limiting the second set-point value based on an absolute value and/or a gradient of the first set-point value; and inputting the second set-point value into a control sequence (20) as a guide magnitude.
