Vehicles with multiple drivetrains, like hybrid electric vehicles, are over-actuated systems with an infinite number of feasible solutions. Hence, energy efficiency, as the secondary objective, is considered to determine the optimum solution. However, the resulting optimisation problem, which is nonlinear due to multi-modal operation of electric machines, must be solved very quickly to comply with stability requirements of vehicles dynamics. A theory is developed for the first time to formulate and parametrically solve the energy-efficient torque distribution problem for vehicles with multiple different drivetrains. The parametric solution is deployable on ordinary electronic control units
(ECUs) as a small-size lookup table that makes it very fast in operation. Simulation results indicate effectiveness of the provided solution as energy management strategies for hybrid electric vehicles and fully-electric ones with multiple different drivetrains.
