Abstract

Systems and methods for reporting data based on monitored emissions levels. An exemplary system automatically provides emissions level data acquired from an engine operating in a roadway vehicle while the vehicle is in motion. Data is made available for vehicle approval by a roadway inspection authority. For example, NOx emissions may be monitored with a sensor positioned in the engine exhaust flow path. Embodiments of the invention provide solutions to reduce time delays associated with inspections.

Claims

1. A system which provides emissions level data acquired from an engine operating in a roadway vehicle while the vehicle is in motion for automated approval by a roadway inspection authority, comprising:

a sensor mounted to receive signals indicative of emissions level information from the engine;

a processing module coupled to

(i) receive and process the signals indicative of the emissions level information while the vehicle is in motion and

(ii) generate emissions level information while the vehicle is in motion for transmittal over a network;

a radio communications system connected to transmit the emissions level information generated by the processing module to a network for receipt by a server associated with an inspection facility or an inspection authority, where;

the processing module operates a program rendering the system responsive to receipt of an identifying radio signal by the radio communications system, which identifying radio signal

(i) identifies an association with the inspection facility or the inspection authority and

(ii) results in the transmission of the emissions level information for receipt by the server

(iii) includes information by which designation of one or more sets of protocols or other requirements is determinable, the program causing the system to respond in accord with the one or more sets of protocols or other requirements, the one or more sets of protocols or other requirements taken from the group consisting of;

(a) a protocol defining how signals are to be processed for confirming emission level compliance for the vehicle while traveling over the roadway,

(b) a protocol for identifying a vehicle enrolled to automatically send radio communication, and

(c) a report format for transmitting emissions information; and

transmitting the emissions reporting information through a radio communications system to a network server for acceptance or approval of vehicle compliance with an emission level requirement of an inspection or compliance authority.

2. The system of claim 1 where, in operating the program, the processing module generates and sends a compliance report to the server.

3. The system of claim 1 where the processing module generates and sends a compliance report to the server and provides emissions level data to another network for receipt by an owner or operator of the vehicle.

4. The system of claim 1 where the program provides a statistically based test using acquired signal data and an emission compliance limit to determine whether a compliance determination is within error limits or whether a determination of non-compliance is within error limits.

5. A method for confirming emissions level compliance of a roadway vehicle, comprising:

acquiring emissions data from one or more sensors mounted on the vehicle;

providing acquired emissions data to a processing module positioned on the vehicle for data accumulation or processing to provide emissions reporting information;

providing timely and early warnings to indicate when a vehicle pollution control system fails to meet requirements or has begun to drift from optimal performance or equipment parameters are outside a prescribed range so that timely repairs can be effected; and

transmitting the emissions reporting information for approval of vehicle compliance with emissions levels requirements of an inspection or compliance authority via radio communication between the vehicle and a network to which the authority is connected to receive the emissions reporting information.

6. The method of claim 5 where the emissions reporting information generated by the processing module is sent to a server at an inspection facility associated with the inspection authority.

7. The method of claim 6 where the steps of providing acquired emissions data and transmitting the emissions reporting information for approval include operating a program on a processing module which renders the system responsive to receipt of an identifying radio signal by the radio communications system, which identifying radio signal (i) identifies the inspection facility and (ii) results in the transmission of the emissions level information for receipt by the server.

8. The method of claim 5 further including providing a statistically based test using acquired signal data and an emission compliance limit to determine whether a compliance determination is within error limits or whether a determination of non-compliance is within error limits.
