Abstract

A method and apparatus in a vehicular telemetry system for determining accelerometer thresholds based upon decoding a vehicle identification number (VIN).

Claims

1. A method of determining a VIN based accelerometer threshold for a vehicular telemetry system comprising the steps of:

receiving a VIN,

decoding said VIN,

determining one of a generic vehicle accelerometer threshold or a specific vehicle accelerometer threshold based upon said decoding said VIN,

setting said VIN based accelerometer threshold as said one of a generic vehicle accelerometer threshold or a specific vehicle accelerometer threshold, and

monitoring accelerometer data for comparing said accelerometer data with said VIN based accelerometer threshold to provide event indications.

2. A method of determining a VIN based accelerometer threshold for a vehicular telemetry system as in claim 1 wherein said event indications are selected from the group of harsh acceleration, harsh braking, harsh cornering or accidents.

3. A method of determining a VIN based accelerometer threshold for a vehicular telemetry system as in claim 1 wherein said accelerometer data is selected from the group of forward, braking or side to side accelerometer data.

4. A method of determining a VIN based accelerometer threshold for a vehicle telemetry system as in claim 1 wherein said VIN based accelerometer threshold pertains to at least one axis of said accelerometer.

5. A method of determining a VIN based accelerometer threshold for a vehicle telemetry system as in claim 1 wherein said VIN based accelerometer threshold is set for each axis of a multi-axis accelerometer.
