<p>The invention provides for a method for controlling a normal force exerted in a frictional contact of a friction type continuously variable transmission with a rotatable input shaft and a rotatable output shaft, which method includes the steps of:-generating a first parameter signal that is representative of changes in one of, or a ratio or difference between both of, a rotational speed of the input shaft and a rotational speed of the output shaft,-generating a second parameter signal that is representative of changes in the normal force in the frictional contact of the transmission,-generating a third parameter signal that is representative of and is preferably proportional to the multiplication of the said first and second parameter signals, and of :-controlling the normal force in the frictional contact in dependence on a characteristic of the third parameter signal.</p> |
