Aspects of the present invention relate to a method of controlling one or more active vanes (2-n) on a host vehicle (VH1) having an energy recovery system (10). The one or more active vanes (2-n) is selectively configurable in a first position and a second position. The method comprises, in respect of one or more current operating parameters of the host vehicle (VH1), determining a first energy expended value (EEV1) and a first energy recovery value (ERV1) associated with the one or more active vanes (2-n) in the first position. A second energy expended value (EEV2) and a second energy recovery value (ERV2) associated with the one or more active vanes (2-n) are determined in respect of the second position. A first difference (D1) is determined between the first energy expended value (EEV1) and the first energy recovery value (ERV1). A second difference (D2) between the second energy expended value (EEV2) is determined and the second energy recovery value (ERV2). The one or more active vanes (2-n) is configured in the first position when the magnitude of the first difference (D1) is greater than the magnitude of the second difference (D2). The one or more active vanes (2-n) is configured configuring the one or more active vanes (2-n) in the second position when the magnitude of the second difference (D2) is greater than the magnitude of the first difference (D1). Aspects of the present invention also relate to a control system (1); a host vehicle (VH1); computer software; and a non-transitory, computer-readable storage medium.
