Abstract

Systems and methods for assessing engine idle condition, comparing current idle conditions to allowable conditions for specific roadway locations, warning drivers and others as to status of current engine idle conditions, and automatically shutting down the engine when idle thresholds are exceeded.

Claims

1. An automated anti-idle warning and shutoff system for a vehicle with an engine operable in an operative zone comprising:

a vehicle sensing system that senses vehicle characteristics;

a vehicle database storing idling parameters;

a vehicle display; and

a shut-off system responsive to the processing of the vehicle characteristics and the idling parameters, wherein the shut-off system can shut off the engine of the vehicle;

wherein at least one of the vehicle characteristics is a characteristic related to engine idling;

wherein at least one of the idling parameters is a parameter related to an allowable idle time threshold for at least one roadway element;

wherein when the characteristic related to engine idling falls outside the parameter related to allowable idle time threshold for at least one roadway element, the vehicle display displays a warning that the shut-off system will shut off the engine of the vehicle in a pre-set time period;

wherein during the pre-set time period, the shut-off system can be overridden so the shut-off system does not shut off the engine of the vehicle; and

wherein, if during the pre-set period, the shut-off system is not overridden, the shut-off system shuts off the engine of the vehicle.

2. The automated anti-idle warning and shutoff system of claim 1, further comprising defining the at least one roadway element by a unique polygon comprising latitude and longitude coordinates bounding an operating zone of the vehicle.

3. The automated anti-idle warning and shutoff system of claim 1, wherein vehicle characteristics further comprise one or more of vehicle position, vehicle speed, vehicle acceleration, vehicle deceleration, and engine operating characteristics.

4. The automated anti-idle warning and shutoff system of claim 1, wherein idling parameters further comprise one or more of vehicle performance parameters, driver demographics, route service characteristics, roadway and land use characteristics, roadway operating conditions, and environmental conditions.

5. An automated anti-idle warning and shutoff system for a vehicle with an engine operating in an anti-idle zone comprising:

a vehicle sensing system that senses vehicle characteristics;

a vehicle processor that records and processes the vehicle characteristics;

a vehicle database storing idling parameters;

an optional communications system to a remote server;

a vehicle display; and

a shut-off system responsive to the processing of the vehicle characteristics and the idling parameters, wherein the shut-off system can shut off the engine of the vehicle and that is triggered locally or remotely from a server by a communications system;

wherein at least one of the vehicle characteristics is a characteristic related to engine idling;

wherein at least one of the idling parameters is a parameter related to an allowable idle time threshold for at least one roadway or other geographic element;

wherein when the characteristic related to engine idling falls outside the parameter related to allowable idle time threshold for at least one roadway or geometric element, the vehicle display displays a warning that the shut-off system will shut off the engine of the vehicle in a pre-set time period;

wherein during the pre-set time period, the shut-off system can be overridden so the shut-off system does not shut off the engine of the vehicle;

wherein, if during the pre-set period, the shut-off system is not overridden, the shut-off system shuts off the engine of the vehicle; and

wherein the at least one roadway or geographic element comprising the anti-idle zone is defined by a unique polygon comprising latitude and longitude coordinates bounding an operating zone of the vehicle.

6. An automated anti-idle warning and shutoff system comprising:

an in-vehicle computer coupled to vehicle sensors that sense vehicle position, speed, and operating parameters;

an in-vehicle database comprising vehicle characteristics, vehicle performance characteristics, driver demographics, route service characteristics, roadway and land use characteristics, roadway operating conditions, environmental conditions, and roadway elements that link vehicle position;

software that runs on the in-vehicle computer that compares engine idle time to anti-idle conditions in real-time, derived from data in the database and the vehicle sensors;

an in-vehicle display for displaying the idle status to the driver of the vehicle in real time; and

an in-vehicle electrical circuit controlled by the in-vehicle computer that changes the state of an electrical or electromechanical device to shut off power to the engine when idle time exceeds anti-idle conditions.

7. The automated anti-idle warning and shutoff system of claim 6, wherein the in-vehicle computer communicates with a remote server that comprises:

a transportation system database that comprises roadway characteristics and roadway operating conditions;

a demographic database comprising driver and passenger demographics;

a revealed vehicle activity database that comprises vehicle activity data;

an environmental database comprising environmental data;

a database comprising the histories of vehicle operating parameters in space and time; and

a processor for computing updated engine idle condition as a function of the data in the respective databases and for updating the idle shutoff status in the software that runs on the in-vehicle computer;

wherein the transportation system database, the demographic database, the revealed vehicle activity database, and the environmental database are linked.

8. The automated anti-idle warning and shutoff system of claim 6, wherein the display presents real-time feedback to the driver relating to vehicle and engine operating parameters that affect engine idle status.

9. The automated anti-idle warning and shutoff system of claim 6, wherein the processor on the in-vehicle system is configured to toggle an electric circuit in response to computed idle condition so as to change the state of an electric or electromechanical device and shut down the engine.
