Method for self-configuring automated mechanical transmission and electronic controller
First Claim
1. A method of ensuring proper automated mechanical transmission and electronic control unit association in a vehicle, comprising the steps of:
- providing a plurality of actuators for translating gear selecting components of a transmission into predetermined positions, providing a plurality of sensors capable of sensing such translation, providing a controller having a program for selecting at least one predetermined gear position, executing said program and comparing data from said sensors with data stored in said controller regarding said predetermined gear position selection, and determining a transmission type by comparison of said stored data with said data from said sensors.

Abstract
A method for self configuring automated mechanical transmissions (AMT) and electronic control units (ECU) ensures compatibility therebetween. The method comprehends undertaking a program or subroutine when the vehicle is first powered up which moves the shift operators into a predetermined position. The shift operators include full stroke sensors. Depending upon differences between the commanded shift pattern and the actual shift pattern of the transmission, the specific type of transmission, for example, a twelve speed or a sixteen speed, can be determined.

8. A method for determining compatibility between a multiple speed automated mechanical transmission and an electronic control unit comprising the steps of:
-
providing a multiple speed transmission having a shift operator assembly including a plurality of actuators and associated position sensors having outputs, providing an electronic control unit having a program comprising the steps of;
commanding one of said actuators to move to a shift position which selects an operating gear in a first type of transmission and selects a non-gear position in a second type of transmission, determining translation of said moving actuator by reading an output of one of said position sensors associated with said moving actuator, comparing said translation of said position sensor with a predetermined value associated with selecting said operating gear in said first type of transmission, and identifying said transmission as a first type if said translation is less than or equal to said predetermined value and identifying said transmission as a second type if said translation is greater than said predetermined value. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method of determining compatible assembly of a transmission with an electronic control unit, comprising the steps of:
-
providing a transmission with at least one gear selecting operator having an associated motion transducer, providing a controller for receiving a signal from said transducer and controlling said operator, commanding said operator to move to a predetermined gear, reading the motion of said transducer, determining a first transmission type if said motion is less than or equal to a predetermined value and a second transmission type if said motion is greater than said predetermined value. - View Dependent Claims (15, 16, 17, 18, 19, 20)
