Abstract
A method is for energy management in a hybrid motor vehicle that includes a power plant coupled with wheels of the vehicle via a transmission according to at least two modes, one of which is currently in use. The method includes determining a quantity of energy representing energy consumption of the power plant and selecting one of the transmission modes according to the quantity of energy. The selecting includes determining a parameter representing an imminent change in torque demand at the wheels, determining a correction factor of the quantity of energy according to the transmission mode currently in use and according to the parameter which represents an imminent change in torque demand, determining a corrected quantity of energy equal to the sum of the quantity of energy plus the correction factor, and selecting the transmission mode in order to minimize the corrected quantity of energy.
