Method for controlling an infinitely variable motor vehicle transmission
First Claim
1. A method for controlling an electro-hydraulically infinitely variable transmission of a driven motor vehicle that has an internal-combustion engine influenced by a power control element, comprising:
- automatically indirectly adjusting the transmission ratio according to at least one characteristic control curve at least as a function of a position of the power control element and of rotational engine speed, wherein the step of adjusting includes the step of selecting a characteristic control curve from a family of characteristic control curves corresponding to a driving activity which evaluates at least one of the driver'"'"'s driving style and action with respect to control of the vehicle caused by a traffic situation, wherein the characteristic control curves cover at least in steps a range between a characteristic control curve which permits consumption-optimized operation of the motor vehicle and a characteristic control curve which permits power-optimized operation of the motor vehicle.

Abstract
A method for controlling an electro-hydraulically operated infinitely variable transmission of a motor vehicle which is driven, in particular, by an internal-combustion engine, provides a control of the infinitely variable transmission according to several characteristic control curves. The characteristic control curves are selected corresponding to a driving activity which evaluates the driver'"'"'s driving style or his action with respect to the control of the motor vehicle caused by a traffic situation. The characteristic control curves cover, at least in steps, the range between a characteristic control curve permitting the consumption-optimized operation of the motor vehicle and a characteristic control curve which permits the power-optimizing operation of the motor vehicle.
