Automotive telemetry protocol

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.

1 . A method of collecting vehicle operation data from a vehicle for later transmission to a remote monitoring recipient in a manner to minimize the bandwidth requirements for the later transmission, comprising the steps of:
 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;   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) assemble an event report based on information contained in the diagnostic information base; and 
 c) package the event report in a protocol data unit according to an SNMP-derived protocol.
