Torque control in an active roll control system

Abstract

Aspects relate to a control system and method for a vehicle suspension system in a vehicle. The control system is configured to: receive a torque request signal indicative of a requested torque value to be applied to an actuator of a roll control system; determine whether the requested torque value is within a predetermined range of torque demand values, wherein the predetermined range covers a zero torque demand value; and if the requested torque is within the predetermined range of torque demand values, output a signal to control the roll control system in dependence on a control function; wherein the control function is configured to: apply and maintain a first predetermined level of torque to the actuator when the requested torque value is positive; and apply and maintain a second predetermined level of torque to the actuator when the requested torque value is negative.

Dependencies are inferred from the claim text.
