Method for energy management in a hybrid motor vehicle

A method for energy management in a hybrid motor vehicle comprising a power plant that includes a heat engine and an electric motor suitable for being coupled with wheels of the vehicle via a transmission device according to at least two transmission modes, one of which is currently in use, the method comprising:

• a) determining a quantity of energy which represents the energy consumption of the power plant;
• and
• b) selecting one of said transmission modes according to the quantity of energy, wherein the selecting includes:
• b1) determining a parameter which represents an imminent change in torque demand at the wheels,
• b2) determining a correction factor of said quantity of energy according to the transmission mode currently in use and according to said parameter which represents an imminent change in torque demand,
• b3) determining a corrected quantity of energy which is equal to the sum of said quantity of energy plus said correction factor, and
• b4) selecting the transmission mode in order to minimize said corrected quantity of energy.
