Abstract
An illustrative controller for a hybrid electric vehicle has a plurality of actuators each operable independently to provide torque to a driveline of the vehicle. At least one of the actuators is arranged to consume a fuel and at least one other comprises an electric machine. The controller is operable to control the plurality of actuators to apply respective amounts of torque to a driveline of the vehicle according to one of three or more operational modes of the vehicle. The respective amounts of torque are based on a value of each of a first set of two or more operating parameters. The controller is arranged to select two or more of the operational modes based on the first set of operating parameters and a value of a cost functional. A first of the selected modes is the mode having the lowest cost functional according to a control optimization methodology.
