The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A system for managing a deactivation of a combustion chamber of a heat engine comprising:
a plurality of combustion chambers, each of which is mounted a piston connected to an output shaft in order to apply a torque thereto,
a rotating machine connected to the output shaft and associated with a management member connected to the rotating machine,
wherein the management member is configured so as to detect conditions of deactivation of a one of the plurality of combustion chambers and to control the rotating machine in order to apply to the output shaft, prior to the deactivation of the one combustion chamber, a compensating torque tending to cause a resultant torque applied to the output shaft to change toward a deactivation torque applied by the heat engine to the output shaft after deactivation of the one combustion chamber.
2. The system as claimed in claim 1, wherein the compensating torque is also applied after the deactivation of the combustion chamber.
3. The system as claimed in claim 2, wherein the rotating machine is controlled so that, at the moment of deactivation, the resultant torque is at an average value between a nominal torque before the deactivation and the deactivation torque.
4. The system as claimed in claim 1, wherein the rotating machine is controlled so that the resultant torque changes in a generally continuous manner.
5. The system as claimed in claim 4, wherein the rotating machine is controlled so that the resultant torque changes in a generally linear manner.
6. The system as claimed in claim 1, wherein the management member is configured to apply to the output shaft a correction torque compensating for an imbalance of the output shaft.
7. The system as claimed in claim 1, wherein the management member is configured to control the rotating machine in order to apply to the output shaft, prior to a reactivation of the combustion chamber, a reactivation compensating torque to the output shaft tending to cause a resultant torque applied to the output shaft to change toward a nominal torque.
8. A method for managing a torque applied to an output shaft of a heat engine comprising combustion chambers; each of which is mounted a piston connected to the output shaft in order to apply a torque thereto, wherein the output shaft is connected to a rotating machine associated with a management member, the method comprising:
detecting conditions of deactivation of a combustion chamber; and
controlling the rotating machine in order to apply to the output shaft, prior to the deactivation of the combustion chamber, a compensating torque tending to cause a resultant torque applied to the output shaft to change toward a deactivation torque applied by the heat engine to the output shaft after deactivation of the combustion chamber.
9. The method as claimed in claim 8, wherein the compensating torque is also applied after the deactivation of the combustion chamber.
10. The method as claimed in claim 9, wherein the rotating machine is controlled so that, at the moment of deactivation, the resultant torque is at an average value between a nominal torque before the deactivation and the deactivation torque.
11. The method as claimed in claim 8, wherein the rotating machine is controlled so that the resultant torque changes in a generally continuous manner.
12. The method as claimed in claim 11, wherein the rotating machine is controlled so that the resultant torque changes in a generally linear manner.
13. The method as claimed in claim 8, further comprising:
applying to the output shaft a correction torque compensating for an imbalance of the output shaft.
14. The method as claimed in claim 8, further comprising:
controlling the rotating machine in order to apply to the output shaft, prior to a reactivation of the combustion chamber, a reactivation compensating torque to the output shaft tending to cause a resultant torque applied to the output shaft to change toward a nominal torque.
15. The method as claimed in claim 14, wherein the reactivation compensating torque is also applied after the reactivation of the combustion chamber.
16. The method as claimed in claim 14, wherein the rotating machine is controlled so that the resultant torque changes in a generally continuous manner.
17. The method as claimed in claim 16, wherein the rotating machine is controlled so that the resultant torque changes in a generally linear manner.
