Abstract:
A system for adjusting the tension of a belt part of a continuously variable transmission, which is mounted downstream of a vehicle engine and is continuously variably adjustable with respect to its transmission ratio, the system comprising:first means for controlling the vehicle engine; second means for controlling the belt transmission; said first means functioning to determine a first signal (Mmot) representing the engine torque of the vehicle engine and functioning to supply the first signal (Mmot) to said second means; said first means further functioning to determine a second signal (&Dgr;Mmot), which represents the quality of said first signal (Mmot) and said first means functioning to supply said second signal (&Dgr;Mmot) to said second means; means for determining a safety reserve (SR) in dependence upon the second signal (&Dgr;Mmot); and, said second means functioning to adjust said tension in dependence upon said first signal (Mmot) and said safety reserve (SR).
