Abstract:
An arrangement for controlling a transmission for a motor vehicle having a drive unit and a drive train, the motor vehicle including a clutch disposed between the drive unit and the transmission, the transmission having a transmission ratio which is continuously variable, the transmission and the drive unit being mounted in the drive train, the drive unit having an adjustable output torque (Mm), the transmission having a drive end and an output end and the transmission including operative means for providing a mechanical operative connection between the drive end and the output end thereof, the arrangement comprising:detection means for detecting a slip (S) representing the slip between said operative means and at least one of said drive end and said output end of said transmission; means for initiating a change (&Dgr;i) of the transmission ratio (i) as a first measure in response to a pregiven value of said slip (S); means for initiating at least one of the following measures in response to said pregiven value of said slip (S): a change (&Dgr;F) of said contact engaging force between said drive end and/or said output end and said operative means in a direction to reduce said slip (S); a drive (&Dgr;MK) of said clutch arranged in said drive train; and, means for initiating a change (&Dgr;Mm) of said output torque of said drive unit as an additional measure in response to said pregiven value of said slip (S).
