Method for controlling a hybrid traction assembly and hybrid vehicle controlled according to such a method
First Claim
1. A method for controlling a hybrid traction assembly of a hybrid vehicle, the hybrid traction assembly, the hybrid traction assembly comprising at least:
- an internal combustion engine;
at least one electric machine which can be mechanically coupled to the driving wheels so as to perform traction of the hybrid vehicle the at least one electric machine being suitable for generating electric regenerative energy when the hybrid vehicle slows down; and
a storage device suitable for delivering electric traction energy to the electric machine and for recovering electric regenerative energy from the electric, generator, wherein the storage device can be connected to an external source of electric power so as to charge the storage device at a high state of charge before a beginning of a vehicle mission;
comprising;
controlling, by an electronic control system, the hybrid traction assembly to cause an initial depleting phase of the storage device at a first mean depletion rate, the the initial depleting rate beginning at the beginning of the vehicle mission and the first mean depletion rate being a high depletion rate;
controlling, by the electronic control system, the hybrid traction assembly to cause at least one sustaining phase of the storage device such that the state of charge of the storage device is maintained in a predetermined sustaining, range; and
controlling, by the electronic control system, the hybrid traction assembly to cause a second depleting phase of the storage device at a second mean depletion rate, the second depleting phase extending between the initial depleting phase and the sustaining phase and the second mean depletion rate being lower than the first mean depletion rate.

Abstract
A method for controlling a hybrid traction assembly includes an initial depleting phase which begins at the beginning of the vehicle mission and where the hybrid traction assembly is controlled to cause depletion of the storage device at a high first mean depletion rate, at least one sustaining phase where the hybrid traction assembly is controlled so that the state of charge is maintained in a predetermined sustaining range. The method further includes a second depleting phase which extends between the initial depleting phase and the sustaining phase, wherein the hybrid traction assembly is controlled to cause depletion of the storage device at a second mean depletion rate, the second mean depletion rate being lower than the first mean depletion rate.
