Patent ID: 8706348

Claim:
A vehicular telemetric method, comprising: receiving an aperiodic and nonrandom trigger signal autonomously produced when a sensed operationally-variable vehicular condition exceeds a pre-set threshold condition, activating a data logging device to log sensed vehicle data, activating a data transmitter to communicate the sensed vehicle data to a remote receiver, and issuing queries to vehicle sensors to obtain the sensed vehicle data, the queries being communicated from a microprocessor via a vehicular communications bus to the vehicle sensors, and receiving responses to the queries via the vehicular communications bus and wherein the trigger signal is issued in response to a first sensor sensing a first operationally-variable vehicular condition that exceeds a first pre-set threshold condition and a second sensor sensing a second operationally-variable vehicular condition that exceeds a second pre-set threshold condition, the second sensor is activated for sensing after the first pre-set threshold condition of the first sensor is exceeded, and the trigger unit issues the trigger signal after the second sensor is activated and after the second pre-set threshold condition of the second sensor is exceeded.
