METHOD AND APPARATUS FOR CONTROLLING THE GRADUALLY VARIABLE TRANSMISSION RATIO OF A SPEED VARIATOR IN A MOTOR VEHICLE

摘要

THE INVENTION RELATES TO A METHOD AND APPARATUS FOR CONTROLLING THE GRADUALLY VARIABLE TRANSMISSION RATIO OF A SPEED VARIATOR. SIGNALS N REPRESENTING THE DIFFERENCE BETWEEN THE ACTUAL SPEED AND THE MOTOR ROTATION SET SPEED ARE APPLIED TO AN INPUT OF A CURVE MEMORY 11, 11 PROVIDING SIGNAL VARIATION SIGNALS; THE SIGNALS REPRESENTING THE ACTUAL ROTATION SPEED N ARE APPLIED TO A DIFFERENTIATION BODY 12 USED TO GENERATE SIGNALS REPRESENTING THE TEMPORAL VARIATION OF THE ACTUAL ROTATION SPEED N; THE SIGNALS REPRESENTING THE VARIATION OF SET SPEED N AND THE VARIATION OF ACTUAL SPEED N ARE APPLIED TO A SUBTRACTION STAGE 13 TO PRODUCE THE REGULATION GAP SIGNALS N TO BE APPLIED TO THE REGULATOR 14.
