The present invention relates to a communications system for handling communications sessions, for example multimedia calls or voice calls. For this purpose, there is provided a control unit for an electric power steering apparatus that controls a motor for giving steering auxiliary force to a steering mechanism based on a current control value calculated from a steering auxiliary command value calculated based on the steering torque generated in the steering shaft, and a current value of the motor. A ventable source of pressurized gas, having an associated pressure transducer and second feedback mechanism, supplies positive force to the foot wrap.
