Engine and transmission control system and method for a motorized vehicle
First Claim
1. A control system comprising:
- an engine having a minimum engine speed and a maximum engine speed;
a transmission having a minimum transmission output speed and a maximum transmission output speed;
an accelerator assembly having a movable member movable within a range of motion defined by a first position based on at least one of said minimum engine speed and said minimum transmission output speed and a second position based on at least one of said maximum engine speed and said maximum transmission output speed; and
a control module that is connected to said accelerator assembly and that adjusts said second position to be based, at least in part, on at least one of a reduced maximum engine speed and a reduced maximum transmission output speed, wherein said range of motion of said movable member remains about constant.

Abstract
The present teachings generally include a control system for a vehicle. The control system includes an engine having a minimum engine speed and a maximum engine speed and a transmission having a minimum transmission output speed and a maximum transmission output speed. The control system also includes an accelerator assembly having a movable member movable within a range of motion. The range of motion is defined by a first position based on at least one of the minimum engine speed and the minimum transmission output speed and a second position based on at least one of the maximum engine speed and the maximum transmission output speed. A control module connects to the accelerator assembly. The control module adjusts the second position to be based on at least one of a reduced maximum engine speed, a reduced maximum transmission output speed and combinations thereof, wherein the range of motion of said movable member remains about constant.

17. An engine and a transmission control system comprising:
-
an accelerator module having a movable member, said movable member having a range of motion defined by a first position, a second position and a plurality of positions therebetween; a mode selector module selectable between at least a first mode and a second mode; and a control module in said first mode that associates said first position with a first value of a vehicle parameter and said second position with a second value of said vehicle parameter and said control module in said second mode associates said second position with a third value of said vehicle parameter, wherein said first value is about less than said second value and wherein said third value is about less than said second value and about greater than said first value. - View Dependent Claims (18, 19)

26. A method for controlling an engine and a transmission comprising:
-
providing an accelerator assembly having an accelerator member movable within a first range of motion; determining a mode; adjusting, at least in part, at least one of an engine speed, a transmission output speed, and a vehicle speed based on said determining said mode; and determining a second range of motion based on said adjusting, at least in part, at least one of said engine speed, said transmission output speed, and said vehicle speed, wherein said first range of motion and said second range of motion are about equal. - View Dependent Claims (27, 28, 29, 30, 31)
