1. A vehicular telematics apparatus comprising:
- a trigger unit; and
,any one or more of;
a data logging device operable to log sensed vehicle data,wherein said data logging device initiates a data logging session in response to a trigger signal issued from the trigger unit in response to a trigger sensor sensing an aperiodic and nonrandom operationally-variable vehicular condition within a normal operational range for such a condition;
a vehicle data transmitter operable to communicate sensed vehicle data to a remote receiver,wherein said vehicle data transmitter initiates a wireless data communication session with said remote receiver in response to a trigger signal issued from the trigger unit in response to a trigger sensor sensing an aperiodic and nonrandom trigger operationally-variable vehicular condition within a normal operational range for such a condition;
a vehicle data query controller operable to conditionally collect data though a vehicular data communications bus, for vehicle data originating from other vehicular data sensors,wherein said data query controller initiates data collection as a conditional response to a contemporaneous trigger signal issued from the trigger unit in response to a trigger sensor sensing an aperiodic and nonrandom operationally-variable vehicular condition within a normal operational range for such a condition.

Abstract
A vehicular telemetry apparatus, operable to initiate a telemetry processing operation in response to an aperiodic, nonrandom trigger signal cued by a sensed, operationally-variable vehicular condition. A trigger unit provides the trigger signal which in turn switches the telemetry apparatus from a resource-conserving idle state to a state in which a session is initiated, so that operationally salient variations in information on changes in vehicle sensor data are detected and processed.
