METHOD AND SYSTEM FOR MANAGING THE POWER OF A HYBRID VEHICLE
First Claim
1. A power management method for a hybrid vehicle selectively driven by an electric motor and by a heat engine, the electric motor being supplied with power by a unit for storing electrical power able to be recharged by the heat engine, wherein a charge level of the power storage unit is monitored in order to select a heat engine or electric motor drive mode, said method comprising steps of:
- evaluating a route profile for the vehicle, associated with a trip of said vehicle; and
evaluating, depending on said route profile, a threshold charge level called the authorized threshold, below which a heat engine drive mode is activated.

Abstract
The invention relates to a method for managing the power of a hybrid vehicle selectively driven by an electric motor and a heat engine, the electric motor being supplied with power by a power storage unit capable of being recharged by the heat engine, wherein according to the method the level of charge of the power storage unit is monitored so as to select the mode in which the vehicle is driven by the heat engine or that in which the vehicle is driven by the electric motor, said method including the steps of: determining a travelling profile of the vehicle associated with a path of said vehicle; and determining (36), according to said travelling profile, a threshold level of charged (S2), referred to as authorised threshold, below which the mode in which the vehicle is driven by the heat engine is activated.
