The control system (100, 200) is configured to: receive a disturbance angle (316) of a roll bar of the vehicle suspension system, the disturbance angle indicative of a determined relative angular displacement between ends of the roll bar caused by the vehicle interacting with a driving surface; receive a displacement value (322) of an actuator motor of the actuator of the vehicle suspension system, the displacement value of the actuator motor indicative of a sensed displacement of the actuator motor caused by the vehicle interacting with the driving surface; determine, in dependence on the disturbance angle of the roll bar and the displacement value of the actuator motor, a torque estimation (332), the torque estimation representing an expected torque provided by the actuator motor to a roll bar connected to the actuator motor; and output the torque estimation to a further vehicle system.

The invention relates to a method for operating a motor vehicle in order to detect an overload on a roll stabilizer which is supported so that it can rotate on a vehicle body and includes two stabilizer parts that can be rotated relative to each other by a torsional angle () via a rotary drive arranged between these parts. In order to detect an impairment to the driving safety of the vehicle in a timely manner, a ratio of the torsional angle () to a variable which is equivalent to an applied torque (M) of the rotary drive is ascertained, and an overload is determined if the ratio lies outside of a specified tolerance range.

A method for measuring torque includes low-pass filtering of a signal supplied by a torque sensor, an analog signal supplied by the torque sensor being first digitized and then processed and forwarded as a digital signal having low-pass characteristics.
