Abstract

This disclosure relates to a steer torque manager (1) for an advanced driver assistance system (26) of a road vehicle (2) and a method therefor. A driver in the loop functionality (13) determines when to hand over control to a driver. A wheel angle controller (14) uses an advanced driver assistance system (26) wheel angle request (3) to produce an overlay torque request (17) to be added to a torque request (7) from an electrical power assisted steering. The steer torque manager (1) controls the driver in the loop functionality (13) based on amplitude and frequency content of a torsion bar torque related signal (6) which is filtered to attenuate an amplitude thereof at frequencies up to 2 Hz. The overlay torque request (17) to be provided by the wheel angle controller (14) is modulated based on a measure of driver activity (22) derived from the filtered torsion bar torque related signal (6), where more recent values are weighted higher than older values, using a time window of 0.5-3 seconds.
