1. A control system for a vehicle, the control system comprising one or more controllers, the control system being configured to:
receive a gaze signal indicative of a direction of a gaze of an occupant of a vehicle, wherein said gaze signal is indicative of an occupant's gaze being directed to a primary driving region, PDR, a secondary driving region, SDR, or a non-driving region, NDR;
determine an attention value indicative of an estimate of the occupant's attention to a driving task, wherein said attention value is changed in a first direction in dependence on the gaze signal being indicative of the occupant's gaze being directed to the PDR, said attention value is changed in a second direction at a first rate in dependence on the gaze signal being indicative of the occupant's gaze being directed to the SDR and said attention value is changed in the second direction at a second rate in dependence on the gaze signal being indicative of the occupant's gaze being directed to the NDR; and
output a signal to cause one or more actions to be performed in dependence on the attention value being equal to or exceeding a predetermined threshold value.
