control module 30 or other vehicle control module or system it should be understood that while in the above description three operating modes u201c track u201d u201c sport u201d and u201c touring u201d having decreasing degrees of aggressive rev matching have been disclosed and described a system having additional rev matching time periods corresponding to four five or more modes which provide correspondingly higher resolution of driver aggressiveness and prime mover response thereto are considered to be well within the scope of this invention and claims in this regard it should also be understood that the number of operating modes may be increased to the extent that the system operates essentially as a fully proportional system matching i e proportioning the rev matching time period to the degree of driver aggressiveness sensed by the sensors 44 56 66 74 and 84 and determined by the control module 30 referring now to fig4 a graphic and qualitative representation of speed or rev matching is illustrated the y axis represents speed rpm of a prime mover 12 and the x axis represents time the dark line 190 represents the speed of the prime mover 12 over time as a manual transmission 20 undergoes first a downshift at a point 192 the present invention commands an increase in the speed of the engine or prime mover 12 represented by the line 194 beginning at the.
