Dynamically assisting hybrid vehicles

Abstract

A system includes a computing device with memory configured to store instructions and a processor to execute the instructions for operations that include receiving information representative of an amount of energy stored over a first period of time in an energy storage device of a vehicle that includes a first propulsion system. Operations include receiving information representative of a performance measure of the vehicle for a second period of time, shorter than the first period of time, and, determining an assistance adjustment from an estimated value of stored energy from the information representative of the amount of energy stored over the first period of time. Operations include determining a level of assistance for a second propulsion system included in the vehicle from the received information representative of the performance measure, and, adjusting the level of assistance using the assistance adjustment determined from the estimated value of the stored energy.
