Abstract
A vehicle, a method, a secondary steering system unit and a secondary steering system are provided. The secondary steering system unit comprises: a fault determination arrangement arranged to determine the presence of a fault in the main steering system and a path controller arranged to generate an upcoming path for the host vehicle. The secondary steering system unit is arranged to steer the host vehicle along the path by differential braking upon determination that a fault is present in the main steering system. Furthermore, the secondary steering system is arranged to control the differential braking in dependence of both a yaw torque acting on the host vehicle as a result of the differential braking and a steering angle resulting from a generated alignment torque on a braked steerable wheel caused by the associated wheel suspension scrub radius.
