## Abstract

The present invention generally relates to automatic transmission controllers and related methods. In one case, the present invention provides a method of calibrating a controller to match an automatic transmission to an electric motor or internal combustion engine. The controller is not integrated into the transmission. The method comprises adjusting parameters of the controller and includes the steps of: a) Defining the Control Architecture; b) using the Defined Control Architecture to Identify Control Loop Input/Output; c) using the Identified Control Input/Output to Define the Control Algorithm Controller; d) using the Control Algorithm Controller definition to either Define the Shift Schedule or Define the Solenoid Handler, either of which can be used in Optimizing Calibration Via Testing.

## Claims

### Claim 1

A method of calibrating a controller to match an automatic transmission to an electric motor or internal combustion engine, wherein the controller is not integrated into the transmission, and wherein the method comprises adjusting parameters of the controller, and wherein the method comprises the steps of: a) defining a control architecture; b) using the defined control architecture to identify control loop input/output; c) using the identified control input/output to define a control algorithm controller; d) using the control algorithm controller definition to define a solenoid handler, thereby activating a transmission solenoid which directs transmission fluid into a valve body engaging the correct gear.

### Claim 2 (depends on 1)

The method of claim 1, wherein the shift schedule receives further input in the form of electric motor efficiency curves, and wherein the defined solenoid handler receives further input from identification of transmission controls requirements.

### Claim 3 (depends on 2)

The method of claim 2, wherein identification of transmission controls requirements is used to select the transmission controller specifications, and wherein the transmission controller specifications are used to choose the transmission controller.

### Claim 4 (depends on 3)

The method of claim 3, wherein the choice of transmission controller provides further input into optimizing calibration via testing.

### Claim 5

A method of calibrating a controller to match an automatic transmission such that the transmission can be matched to any electric motor or internal combustion engine, wherein the method comprises the steps of: a) defining a control architecture; b) using defined control architecture to identify control loop input/output; c) using the identified control input/output to define an algorithm controller; d) using the control algorithm controller definition to define a solenoid handler, thereby activating a transmission solenoid which directs transmission fluid into a valve body engaging the correct gear.

### Claim 6 (depends on 5)

The method of claim 5, wherein the transmission is matched to an electric motor.

### Claim 7 (depends on 5)

The method of claim 5, wherein the transmission is matched to an internal combustion engine.
