A steer torque manager for an advanced driver assistance system of a road vehicle and a method therefor. A driver-in-the-loop functionality determines when to hand over control to a driver. A wheel angle controller uses an advanced driver assistance system wheel angle request to produce an overlay torque request to be added to a torque request from an electrical power assisted steering. The steer torque manager controls the driver-in-the-loop functionality based on amplitude and frequency content of a torsion bar torque related signal which is filtered to attenuate an amplitude thereof at frequencies up to 2 Hz. The overlay torque request to be provided by the wheel angle controller is modulated based on a measure of driver activity derived from the filtered torsion bar torque related signal, where more recent values are weighted higher than older values, using a time window of 0.5-3 seconds.
