Abstract

A engine controller includes a connector having pins that provide an electrical connection between devices external to the controller and internal electrical components. The programming tool is used to program the controller to assign particular pins to transmit or receive certain signals.

Claims

1. A configurable control system, comprising:

an electronic control module configurable to control the operation of one or more devices external to the electronic control module, the electronic control module including one or more pins and being configurable to receive at least one data input signal on at least one of the pins and further being configurable to create and transmit at least one control signal as a function of the data received through the at least one data input signal;

at least one input device external to the electronic control module and coupled with at least one input pin of the electronic control module, the at least one input device being operable to transmit the at least one data input signal;

at least one responsive device external to the electronic control module and coupled with at least one output pin of the electronic control module, the at least one responsive device being operable to execute a desired response as a function of the at least one control signal; and

a programming tool external to, and operable to be coupled with, the electronic control module, the programming tool being operable to configure the electronic control module to (i) receive the at least one data input signal over the at least one input pin, (ii) create the at least one control signal, and (iii) transmit the at least one control signal over the at least one output pin.

2. The configurable control system of claim 1, further comprising a connector element;

wherein the at least one input pin and the at least one output pin are arranged within the connector element.

3. The configurable control system of claim 2, wherein at least one input device and at least one responsive device are coupled to the electronic control module via the connector element.

4. The configurable control system of claim 2, wherein the programming tool is configured to be connectable to the connector element.

5. The configurable control system of claim 1, wherein the at least one responsive device is an engine component.

6. The configurable control system of claim 1, wherein the at least one responsive device is at least one of a switch, a sensor, an actuator, and a fuel injector.

7. The configurable control system of claim 1, wherein the programming tool is distinct from, and external to, the at least one input device and the at least one responsive device.

8. The configurable control system of claim 1, wherein:

the electronic control module is configurable to receive at least two data input signals, each signal being receivable on an input pin, the electronic control module further being configurable to create and transmit at least one control signal as a function of the data received through all of the at least two data input signals;

at least two input devices external to the electronic control module are each coupled with at least one input pin of the electronic control module and operable to transmit at least one data input signal; and

the programming tool is operable to configure the electronic control module to (i) receive each of the at least two data input signals over the respective input pin, (ii) create the at least one control signal, and (iii) transmit the at least one control signal over the at least one output pin to the at least one responsive device.

9. A method for configuring an electronic control module to control one or more responsive devices, the electronic control module having a plurality of pins for (i) receiving one or more data input signals from one or more input devices and (ii) transmitting one or more control signals to one or more responsive devices, the method comprising:

determining one or more data input signals to be received by the electronic control module;

determining one or more control signals to be (i) created by the electronic control module as a function of the one or more data input signals and (ii) transmitted by the electronic control module over one or more of the pins to at least one responsive device external to the electronic control module;

coupling an external programming tool to the electronic control module;

configuring, via the external programming tool, the electronic control module to (i) receive the one or more data input signals over one or more respective pins, (ii) create at least one control signal as a function of the data received through the one or more data input signals, and (iii) transmit the one or more control signals over one or more respective pins; and

decoupling the external programming tool from the electronic control module.
