Abstract
An autofunction control system for motor vehicles comprising an engine, a transmission and an accelerator, the position of the accelerator defining a set ERPM, the system configured to define a desired percentage of maximum available power for each set ERPM, the system configured to control the transmission ratio of the transmission to load the engine at least to the desired percentage of power, wherein the desired percentage of power is a function of the set ERPM when the set ERPM is between a low threshold and a high threshold, and wherein the system is configured to control the transmission ratio to load the engine closest to the maximum available absolute power for the engine for a set ERPM above the high threshold ERPM.
