A controller for an electric power assisted steering (ePAS) system, which permits articulation of one or more vehicle wheels within a steering angle range, is configured to adjust a maximum available steering lock for the ePAS system in dependence on a plurality of inputs (I1, I2, I3, I4, I5), which may include vehicle parameters such as vehicle speed and non-vehicle parameters such as terrain features and weather conditions. This may allow the amount of steering range to be adjusted according to conditions while avoiding damage to a tyre from contacting a wheel arch cavity. Haptic feedback may be provided if a driver exceeds a maximum available steering lock. A vehicle and control method are also provided.
