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.

10. A method for managing energy from a propulsion unit in response to a request for torque by a driver of a hybrid vehicle including an internal combustion engine and at least one electric motor powered by a battery, able to recover energy during deceleration, following a management law distributing in real time an energy supply from the internal combustion engine and from the electric motor, wherein the energy management law depends:
-
on an equivalence factor which is a function of a momentary energy state of the battery, an energy target, and driving conditions of the vehicle determined in a regulation loop, able to minimize global energy consumption of the vehicle at an operating point of the propulsion unit; and on a discharge feed-forward factor which is a function of potential energy recoverable during deceleration. - View Dependent Claims (11, 12, 14, 15, 16, 17, 18)
