Abstract

A method and system for controlling a compression ignition electronic control module equipped compression ignition internal combustion engine installed in a vehicle to provide enhanced vehicle road speed limiting to conform to requirements of a geographical location.

Claims

1. A method for vehicle controlling an electronic control module equipped internal combustion engine vehicle road speed limiting to conform to requirements of a geographical location, comprising;

determining the geographical location of the engine;

determining whether the engine is located within a geographical location that requires mandatory road speed limiting;

determining the road speed limit in the geographical location;

determining whether the mandatory road speed limiting is enabled;

determining whether vehicle road speed equals a minimum programmed road speed limiting allowed by the geographical location;

determining whether a speed limit equals a minimum mandatory road speed limiting; and

limiting the vehicle road speed to the speed limit in the geographical location.

2. The method of claim 1, wherein the electronic control module is equipped with look up tables that contain data that may be used to determine the road speed limit permitted by any given geographical location.

3. The method of claim 1, wherein said geographical location of the engine is communicated to the electronic control module by wireless communication.

5. The method of claim 1, wherein said geographical location of the engine is communicated to the electronic control module by a hand held device through an interface to the electronic control module.

6. The method of claim 1, wherein the mandatory road speed limit and the programmed road speed limit change dynamically.

7. The method of claim 1, wherein said power take off mode includes said auxiliary power mode.

8. The method of claim 1, wherein said geographical location is a state within the United States of America.

9. The method of claim 1, wherein the vehicle speed is limited by limiting the delivery of fuel to the engine.

10. The method of claim 1, further including determining whether the engine is loaded with auxiliary devices.

4. The method of claim 4, wherein said wireless communication is a global positioning satellite transmission signal.

11. A system for controlling a compression ignition internal combustion engine installed in a vehicle to limit vehicle speed to conform to the requirements of a geographical location, comprising:

a vehicle speed sensor that provides an indication of vehicle speed;

an engine controller with tables containing fueling strategies;

said controller in communication with the vehicle speed sensor, the accelerator sensor, a plurality of switches, various fueling strategies, and at least one sensor for determining engine load, the engine controller capable of receiving a communication indicating the geographical location of a vehicle and monitoring at least the vehicle speed sensor to determine vehicle speed and whether fuel is being requested;

determining the geographical location of the vehicle;

determining the fueling strategy that will conform the vehicle speed to the requirements of the geographical location, and limiting fuel delivery to the engine in accordance with said strategy.
