METHOD FOR CONTROLLING A SERIES HYBRID ELECTRIC VEHICLE
First Claim
Patent Images
1. A method for controlling operation of a vehicle having a primary power source (PPS) and an energy storage system (ESS), the PPS and ESS providing electric power to a motor for driving the vehicle, the method comprising:
- calculating a motor power demand;
calculating an ESS power demand;
calculating a PPS power demand to meet the motor and ESS power demands; and
controlling PPS power output to meet the PPS power demand, the PPS power output controlled being based on a PPS power schedule that includes predefined PPS operating parameters to produce PPS fuel efficiency for the PPS power demand.
