ABSTRACT:
BACKGROUND OF THE INVENTION
The invention refers to a power train control for overall control of a prime mover and a transmission for a vehicle or an automotive machine with a prime mover with speed control and a continuously variable transmission with ratio control.
SUMMARY OF THE INVENTION
A power train control for a tractor management system is outlined in an article by
A. Jaufmann, O+P Ölhydraulik und Pneumatik
41 (1997) Nr. 4, 234-241. Details regarding control and regulation strategies or algorithms for the management of the complete system made up of prime mover and transmission, however, are not dealt with.
The objective of the invention is to come up with a power train control which controls a power train including the components prime mover with speed governor and CVT with ratio control in such a way that minimum energy is consumed, but the performance/traction required is available when needed. The transitions between the set combinations of speed of prime mover and gear ratio are to be effected promptly and in a stable manner.
This task is solved by means of a generic power train control which is also provided with the characteristic features of the main claim.
Specific versions of the invention are detailed in the sub-claims.
