Abstract

This disclosure relates to a method of configuring an engine control system for controlling the engine of a vehicle. The method involves displaying one or more graphical representations of functional elements to be performed by the engine control system and then modifying the one or more functional elements by making changes to the displayed graphical representations. This allows the engine control system to be readily reconfigured by a user. This disclosure also relates to an apparatus for configuring an engine control system and a new engine control system. A computer program product including a computer readable medium having a computer program recorded on it for configuring an engine control system is also disclosed.

Claims

1. A method of configuring an engine control system for use in controlling the engine of a vehicle, comprising:

displaying one or more graphical representations of functional elements each defining one or more arithmetic or logical operations to be performed by said engine control system; and

modifying one or more of the functional elements by making changes to the displayed graphical representations in order to configure the engine control system.

2. The method according to claim 1, wherein the modifications are made during continuous operation of the engine.

3. The method according to claim 1, wherein the modifications further comprise changing connections between the graphical representations.

4. The method according to claim 1, wherein the modifications further comprise assigning one or more inputs and outputs of the engine control system to one or more of the graphical representations.

5. The method according to claim 1, wherein the modifications further comprise changing links between the functional elements.

6. The method according to claim 1, further comprising:

simulating operation of the engine control system based on pre-stored engine data.

7. The method according to claim 1, wherein the engine control system provides audio queues to a user during the modification of the functional elements.

8. The method according to claim 1, wherein the engine control system provides audio feedback of as to a current state of engine behaviour.

9. The method according to claim 8, wherein the audio feedback represents knocking sounds generated by the engine of the vehicle.

10. The method according to claim 1, wherein the functional elements further comprise one or more of the following:

(i) a single dimensional tables with interpolated outputs;

(ii) a two dimensional tables with interpolated outputs;

(iii) a summer;

(iv) a multiplier;

(v) a divider;

(vi) a splitter;

(vii) a saturator;

(viii) a comparator;

(ix) a multiplexer;

(x) a timer;

(xi) a latch;

(xii) a delay line;

(xiii) a logical operation with arbitrary inversion;

(xiv) a proportional-integral-derivative controller;

(xv) a display; and

(xvi) a gauge.

13. An engine control system configured in accordance with the method of claim 1.

11. An apparatus for configuring an engine control system for use in controlling the engine of a vehicle, comprising:

a display for displaying one or more graphical representations of functional elements each defining one or more arithmetic or logical operations to be performed by said engine control system; and

a processor for modifying one or more of the functional elements by making changes to the displayed graphical representations in order to configure the engine control system.

12. A computer readable medium, having a program recorded thereon, Where the program is configured to make a computer execute a procedure to configure an engine control system for use in controlling the engine of a vehicle, said program comprising:

a code for displaying one or more graphical representations of functional elements each defining one or more arithmetic or logical operations to be performed by said engine control system; and

a code for modifying one or more of the functional elements by making changes to the displayed graphical representations in order to configure the engine control system.

14. An engine control system for controlling the engine of a vehicle, said engine control system comprising:

a memory for storing one or more functional elements each defining one or more arithmetic or logical operations to be performed by said engine control system; and

a processor for executing the one or more functional elements to control the engine, wherein the functional elements are modifiable by making changes to one or more displayed graphical representations of the functional elements while the engine is operating.
