Systems and methods for implementing dynamic operating modes and control policies for hybrid electric vehicles

A method for optimizing an operation of a powertrain for an HEV vehicle, the powertrain for the HEV vehicle comprising a prime mover;

• a first electric motor-generator, said first electric motor-generator mechanically coupled to said prime mover via a first clutch;
• a second electric motor-generator, said second electric motor-generator mechanically coupled to said first electric motor-generator via a second clutch;
• a battery, said battery electrically coupled to said first electric motor-generator and said second electric motor-generator, said battery configured to supply electrical energy to said first electric motor-generator and said second electric motor-generator;
• and a controller, said controller configured to receive signals from one or more sensors and supplying control signals to said prime mover, said first clutch, said first electric motor-generator, said second clutch and said second electric motor-generator;
• said method comprising:
• determining torque and speed of the first electric motor-generator;
• determining torque and speed of the second electric motor-generator;
• upon a power demand by a user, determining a combination of torque and speed of both first electric motor-generator and said second electric motor-generator according to motor efficiency information of both first electric motor-generator and said second electric motor-generator;
• wherein determining the combination of torque and speed further comprise:
• determining coefficients, a and b, such that the combination of (a*M1) +(b*M2) is more efficient than other coefficients;
• and
• wherein M1 and M2 are the respective efficiencies of the first electric motor-generator and the second electric motor-generator;
• and
• further wherein the combination of torque and speed of both first electric motor-generator and said second electric motor-generator is more efficient than other combinations of said torque and speed.
