A control system (208) for computing a power threshold for activating and deactivating an electric propulsion mode of a hybrid electric vehicle (10) is described. The control system (208) is configured to receive route information concerning a journey planned to be undertaken by the vehicle (10), determine, from the route information, a driving profile for the journey, the driving profile comprising an expected vehicle speed for each of a plurality of segments of the journey, and determine an adjusted vehicle speed for each segment in dependence on an adjustment factor, the adjustment factor being based on historical driving data for the vehicle (10). The power threshold is then determined for the vehicle (10) based on the adjusted vehicle speeds for each segment of the journey; and a signal is output in dependence on the determined power threshold. In this way, the vehicle speed threshold calculation is able to consider the manner in which the vehicle (10) has previously been driven, by applying an adjustment factor to more generic vehicle speed information, the adjustment factor being based on historical driving data. This improves the utilisation of the electric propulsion mode.
