Abstract
A method for controlling a torque of a roll stabilizing system which acts on a wheel suspension system of a chassis for a vehicle in order to correct a rolling inclination of the bodywork of a vehicle, wherein a spring travel value of at least two wheels of the vehicle is detected. The torque is determined as a function of a difference between the spring travel values of the two wheels, and the determined torque is applied to the wheel suspension system. An actual torque which acts on the wheel suspension system is preferably determined on the basis of the differences between the spring travel values. The actual torque is used to calculate a setpoint torque for a roll stabilizing system.

A method for controlling a torque of a roll stabilizing system which acts on a wheel suspension system of a chassis for a vehicle in order to correct a rolling inclination of a bodywork of the vehicle, wherein a spring travel value of at least two wheels of the vehicle is detected, wherein the torque is determined as a function of a difference between the spring travel values of the two wheels, wherein the determined torque is applied to the wheel suspension system, and wherein each spring travel value is a measure of a relative distance between one of the wheels and the bodywork of the vehicle.
A method for controlling a torque of a roll stabilizing system which acts on a wheel suspension system of a chassis for a vehicle in order to correct a rolling inclination of a bodywork of the vehicle, wherein a spring travel value of at least two wheels of the vehicle is detected, wherein the torque is determined as a function of a difference between the spring travel values of the two wheels, wherein the determined torque is applied to the wheel suspension system, wherein a spring compression speed of the wheels is detected, and wherein differences between the spring compression speeds are taken into account during determination of the torque.
A method for controlling a torque of a roll stabilizing system which acts on a wheel suspension system of a chassis for a vehicle in order to correct a rolling inclination of a bodywork of the vehicle, wherein a spring travel value of at least two wheels of the vehicle is detected, wherein the torque is determined as a function of a difference between the spring travel values of the two wheels, wherein an electric motor is used as an actuator, wherein the electric motor is operatively connected to the wheel suspension system, and wherein the torque is applied to the wheel suspension system using the electric motor, wherein an angular position of a rotor of the electric motor is taken into account as a measure of the rotation of the actuator which interacts with two rotatable stabilizer halves.
