PCT No. PCT/FR95/00384 Sec. 371 Date Apr. 15, 1996 Sec. 102(e) Date Apr. 15, 1996 PCT Filed Mar. 28, 1995 PCT Pub. No. WO95/26893 PCT Pub. Date Oct. 12, 1995The present invention relates to a method of governing a system such as a vehicle screen wiping system. It also relates to a governing apparatus for performing the method of the invention, and to a governed system of the simultaneous or synchronized type, for wiping a glass surface of a vehicle. The governing apparatus according to the invention includes a low level control module which effects, in the system, a reversion to a stable state. The command signal from the low level control module is generated by an intermediate level control module which operates as an open loop. Finally perturbations are compensated for by a high level control module which produces a modification of the command signals in such a way as to render the governing action convergent. The modification of the command signals consists in reducing the rate of propagation of the command signals when the load increases.!
