Abstract
A method for managing a torque applied to an output shaft of a combustion engine, the combustion engine including combustion chambers, in each of which there is mounted a piston connected to the output shaft in order to apply a torque to it, the output shaft being connected to a rotary machine associated with a management member. The method involves detecting conditions of deactivation of one combustion chamber and controlling the rotary machine so as to apply to the output shaft, prior to the deactivation of one combustion chamber, a compensating torque which tends to cause a resultant torque applied to the output shaft to tend towards a deactivation torque applied by the combustion engine to the output shaft after deactivation of the combustion chamber.
