The invention relates to a controller (140) for a hybrid electric vehicle (HEV), the controller (140) being operable to control a HEV to assume a HEV mode of operation in which each of a plurality of actuators (121, 123) of a HEV is controlled to assume a prescribed operational state, the controller being configured to control a HEV to assume an operational mode responsive to data in respect of a route of a journey to be made by a HEV, a route comprising at least one route segment, the controller (140) being configured to determine a target state of charge of an energy storage device (150) of a HEV for each said at least one route segment being a state of charge of an energy storage device (150) that is to be achieved at the end of said at least one segment responsive to the data in respect of a route, the controller (140) being further configured to control the HEV to achieve the target state of charge at the end of said at least one segment. |
