Patent number: 9283824Abstract: 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.Type: GrantFiled: June 24, 2014Date of Patent: March 15, 2016Assignee: Dr. Ing. h.c. F.
