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.

Method for controlling a torque of a roll stabilizing system

A method and device for roll stabilization of a motor vehicle are provided. On the basis of a measured transverse acceleration or a calculated transverse acceleration of the motor vehicle, actuating signals are generated for actuators which are associated with a front axle and a rear axle of the motor vehicle and which provide support torques on the front axle and/or on the rear axle for roll stabilization. To ensure a satisfactory self-steering effect of the motor vehicle, a torque distribution between the support torque provided on the front axle and the support torque provided on the rear axle is modified on the basis of a first signal which allows conclusions to be drawn concerning the actuation of a gas pedal, and/or on the basis of a second signal which allows conclusions to be drawn concerning the actuation of a brake pedal.

Method and device for roll stabilization of a motor vehicle

A process for stabilizing the sway of a motor vehicle, in which adjusting signals are generated for actuators associated with a front axis and with a rear axis of the motor vehicle on the basis of a measured or a calculated transverse acceleration of the motor vehicle, which actuators make support moments available on the front axis and/or on the rear axis for stabilizing the sway. Accordingly the measured transverse acceleration and the calculated transverse acceleration are used in at least one speed range of the motor vehicle in such a manner to generate the adjusting signals for the actuators that either the calculated transverse acceleration or the measured transverse acceleration is used to generate the adjusting signals in dependence on an absolute value of the difference between the calculated transverse acceleration of the motor vehicle and the measured transverse acceleration of the motor vehicle.
