The subject of the present invention is a method for preventing the stalling of the engine of a hybrid vehicle (1) equipped with an auxiliary motor (4), generally of an electric motor, and associated equipment: wheels (R1 to R4), pistons (2a to 2d), tank (3), axle (5), transmission shaft (6), gearbox (7), connections (8a, 8b), computer (9). The method uses an estimate of the predicted instantaneous speed of the main engine (2) at its next top dead centre so as to be able to assist the main engine (2) in a stalling situation, using the auxiliary motor (4) capable of temporarily supplying it with enough energy that it does not stall. The method defines two instantaneous-speed levels. If the prediction of the predicted instantaneous speed falls within the intervention zone between the two levels, the auxiliary motor (4) assists the rotation of the main engine (2) to allow it to turn in the same direction without stalling. |
