Abstract
A method for managing energy in response to a request of a driver for torque on a power train of a hybrid vehicle including a heat engine and at least one electric motor powered by a battery, capable of recovering energy during deceleration in accordance with a management rule distributing the energy supply from the heat engine and from the electric motor in real time. The energy-management law depends on: an equivalence factor that is based on an instantaneous energy state of the battery, an energy target, and travel conditions of the vehicle; and a discharge precompensation factor that is based on energy potential that can be recovered during deceleration.
