Abstract

Disclosed is a method of conveying vehicle operation data from a vehicle to a remote monitoring recipient, comprising the steps of establishing a data link between the vehicle and the remote monitoring recipient; collecting vehicle operation data from data sources in the vehicle; packaging the vehicle operation data in a data packet using protocol derived from SNMP; and conveying the data packet over the data link.

Claims

1. A method of collecting vehicle operation data from a vehicle for later transmission, over a public communication channel including a wireless data link, to a plurality of authorized remote monitors, comprising:

providing a vehicle on-board computing device;

providing a number of data acquisition modules, each to measure one or more operating characteristics of the vehicle, the operating characteristics corresponding to current values of a set of managed objects, the set of managed objects being configured according to an SNMP-derived protocol;

interfacing the vehicle on-board computing device with each of the data acquisition modules;

configuring the vehicle on-board computing device to;

a) form a diagnostic information base for receiving and storing values for each of the managed objects from each of the corresponding data acquisition modules;

b) receive and store values for each of the managed objects in the diagnostic information base; and

c) form a list of the plurality of authorized remote monitors, and index the list so that at least one authorized remote monitor is permitted to receive a managed object value that another authorized remote monitor is not permitted to receive, and to store the index;

enabling the vehicle on-board computing device to;

a) assemble an event report to report a vehicular event, of a type not requiring an acknowledgement from an authorized remote monitor, based on the values of the corresponding objects;

b) package the event report in a TRAP protocol data unit according to the SNMP-derived protocol, the TRAP protocol data unit reporting a GPS position, for dispatch to an authorized remote monitor; and

c) establish communication with the authorized remote monitor according to the stored index, over the public communication channel; and

to dispatch the TRAP protocol data unit to the authorized remote monitor.

4. A method as defined in claim 1, the SNMP-derived protocol including a protocol stack having a Secure Sockets Layer (SSL) security layer.

2. A method of collecting vehicle operation data from a vehicle for later transmission, over a public communication channel including a wireless data link, to a plurality of authorized remote monitors, comprising:

providing a vehicle on-board computing device;

providing a number of data acquisition modules, each to measure one or more operating characteristics of the vehicle, the operating characteristics corresponding to current values of a set of managed objects, the set of managed objects being configured according to an SNMP-derived protocol;

interfacing the vehicle on-board computing device with each of the data acquisition modules;

configuring the vehicle on-board computing device to;

a) form a diagnostic information base for receiving and storing values for each of the managed objects from each of the corresponding data acquisition modules;

b) receive and store values for each of the managed objects in the diagnostic information base; and

c) form a list of the plurality of authorized remote monitors, and index the list so that at least one authorized remote monitor is permitted to receive a managed object value that another authorized remote monitor is not permitted to receive, and to store the index;

enabling the vehicle on-board computing device to;

a) assemble an event report to report an exceptional vehicular event, in which a regulatory threshold level has been exceeded, and of a type requiring an acknowledgement from the authorized recipient;

b) package the event report in an INFORM protocol data unit according to the SNMP-derived protocol, for dispatch to an authorized remote monitor;

c) establish communication with the authorized remote monitor according to the stored index, over the public communication channel; and

to dispatch the INFORM protocol data unit to the authorized remote monitor;

d) wait for a confirmation that the INFORM protocol data unit has been logged in a data base by the authorized remote monitor.

3. A method as defined in claim 2, further comprising the step of re-transmitting the INFORM protocol data unit in the absence of a confirmation that the INFORM protocol data unit has been logged in a database by the authorized remote monitor.

5. A method as defined in claim 2, the SNMP-derived protocol including a protocol stack having a Secure Sockets Layer (SSL) security layer.
