Method for optimizing the energy consumption of a plug-in hybrid vehicle

Abstract

This method for optimizing the energy consumption of a hybrid vehicle with a powertrain comprising a fuel-powered internal combustion engine and at least one electric motor powered by a traction battery rechargeable via mains power includes the following steps: determining two cost parameters; determining three equivalence coefficients for each possible configuration of the vehicle's powertrain; and, based on these three equivalence coefficients, calculating the values ​​of three optimization functions. Using an arbitration function, identifying an optimal powertrain configuration based on the calculated values ​​of the three optimization functions; selecting a powertrain configuration setpoint representative of the optimal powertrain configuration; and controlling the powertrain to comply with the setpoint.
