This disclosure relates to a steer torque manager (STM) (1) for an advanced driver assistance system (ADAS) (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 ADAS (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 STM (1) is arranged to receive an assistance torque related signal (6). When driver assistance is provided by the ADAS (26), the STM (1) is arranged to feed forward and subtract from the overlay torque request (17) a feed forward signal (21) scaled to be a scaled version of the assistance torque related signal (6), using a scale factor in the range [0,1] assuming low values if the measure of driver activity (22) indicates high driver activity and higher values if the measure of driver activity (22) indicates low driver activity.
