An efficiency autonomous driving strategy which accounts for the propulsion system efficiency and energy consumption during vehicle motion planning function required for autonomous driving. Specifically, a control algorithm calculates the required energy and total efficiency for various possible vehicle path/motion plans being considered by the autonomous driving (AD) controller. Given at least one or more desired vehicle motion plans, the propulsion system selects the vehicle motion path with the highest efficiency and least energy consumption. The control algorithm accounts for the current vehicle motion (speed/acceleration, etc.), and future vehicle motion requirements for a given vehicle path plan. The control algorithm calculates the total vehicle energy required (current time up to future time) for the proposed vehicle motion plans, then recommends the most efficient vehicle motion plan to the AD controller such that total energy consumption is reduced.
