Controller and method of control of a hybrid electric vehicle
First Claim
1. A controller for a hybrid electric vehicle having a plurality of actuators, at least one of the actuators being arranged to consume a fuel and at least one of the actuators comprising an electric machine operable to be powered by an energy storage device;
- the controller being operable to control the plurality of actuators to apply respective amounts of torque to a driveline of the vehicle according to one of a plurality of operational modes of the vehicle in dependence on a value of a first set of two or more operating parameters of the vehicle,the controller being arranged to select two or more of the operational modes in dependence on the first set of operating parameters, the modes being selected in dependence on a value of a cost functional, a first of the selected modes being the mode having the lowest cost functional according to a control optimisation methodology implemented by the controller;
wherein the controller is arranged to control the vehicle to assume the first of the selected modes and in the event the first selected mode is unavailable the controller is arranged to control the vehicle to assume another of the selected modes.

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.

23. A method of controlling a hybrid electric vehicle having a plurality of actuators each operable to provide torque to a driveline of the vehicle, at least one of the actuators being arranged to consume a fuel and at least one of the actuators comprising an electric machine operable to be powered by an energy storage device. the method comprising:
-
receiving at a controller a value of each of a first set of two or more operating parameters of the vehicle; selecting two or more operational modes of the vehicle from a set of three or more operational modes responsive to the first set of operating parameters, each mode corresponding to a prescribed configuration of respective amounts of torque applied to the driveline by the plurality of actuators; selecting the two or more modes responsive to a value of a cost functional, a first of the selected modes being the mode having the lowest cost functional according to a control optimisation methodology implemented by the controller; controlling the vehicle to assume the first of the selected modes; and in the event the first selected mode is unavailable, controlling the vehicle to assume another of the two or more selected modes. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32)
