Abstract (en)
[origin: WO2015067874A1] The invention mainly relates to a method for controlling the torque of a heat engine provided with a first governor (4), referred to as idling speed control valve, capable of generating an idling torque (Cral) intended for maintaining a predetermined set idling speed (Wral) such as to prevent said heat engine from stalling, and a second governor (6), referred to as a curative smoothing governor, capable of compensating for an oscillation in the speed of the heat engine (Wm) by applying a corrective torque in phase opposition with the speed of the heat engine (Wm), characterised in that in the event of simultaneous activation of the idling speed control valve (4) and the curative smoothing governor (6), said method comprises the step of attenuating said corrective torque produced by said curative smoothing governor (6) without cancelling same unless there is a risk of the heat engine stalling. The invention also relates to the corresponding engine computer.
