Abstract

A method for torque split arbitration in a vehicle includes identifying at least one route characteristic of a portion of a route being traversed by the vehicle. The method further includes determining a target torque split based on the at least one route characteristics. The method further includes generating a first output torque demand that corresponds to a product of a first portion of a target torque demand to be provided by a first propulsion unit and a ratio of a total propulsion system torque demand and the target torque demand. The method further includes generating a second output torque demand based on the first output torque demand.
