Load balancing approach to execute cost optimization in multi-mode and multi-gear hybrid electric vehicles

A control method for balancing controller computational processing loads in a vehicle, the control method comprising:

• providing a controller configured to control operation of the vehicle including executing at least some of a plurality of functions in response to a function trigger corresponding to a particular operating condition of the vehicle, wherein the plurality of functions include vehicle speed control, vehicle torque control, and vehicle transmission control and the function trigger includes a position of a rotating shaft of the vehicle;
• providing a memory configured to store offline testing data captured by offline testing of the controller executing the plurality of functions, the offline testing data indicating runtimes of the plurality of functions;
• determining, by the controller, a set of allowed functions from the plurality of functions based on a set of constraints corresponding to a set of operating parameters of the vehicle;
• dividing, by the controller, the set of allowed functions into a plurality of subsets to obtain a plurality of subsets of allowed functions;
• based on the offline testing data, equally assigning, by the controller, the plurality of subsets of allowed functions across N instances of the function trigger, wherein N is an integer greater than one;
• and
• executing, by the controller, the set of allowed functions across the N instances of the function trigger as equally assigned to balance a computational load on the controller.
