PCT No. PCT/EP94/03606 Sec. 371 Date May 6, 1996 Sec. 102(e) Date May 6, 1996 PCT Filed Nov. 2, 1994 PCT Pub. No. WO95/12751 PCT Pub. Date May 11, 1995The invention applies to the control of the variable opening and closing of an intake valve. According to the invention, a set-point position ( alpha c) for an event related to the valve is calculated continuously. Upon the detection of a change in the set-point ( alpha c) or in the engine speed (N), the establishment of the new set-point is controlled in an open loop during at least the first engine cycle following the detection of the set-point change, and b) the adjustment to the new set-point is controlled in a closed loop during subsequent engine cycles. The control is applied to a mechanism for triggering the event with an advance (AV) on the event. In each open-loop control cycle, this advance is read in a stored table, as a function of the engine speed (N) and the set-point position ( alpha c)calculated for the event.
