1. A vehicle accelerometer system, comprising:
- an accelerometer for installation in a vehicle;
a processor for selection of accelerometer output data items for inclusion in an accelerometer output data set representative of measurements by the accelerometer at a plurality of different vehicle locations, each accelerometer output data item being representative of a respective measurement by the accelerometer; and
a storage device for storing the accelerometer output data set,wherein the processor is configured to;
compute, using each of the plurality of measurements by the accelerometer at the respective different vehicle locations from the accelerometer output data set, an orientation output representative of the orientation of the accelerometer with respect to the vehicle, the orientation output comprising a reference output representative of the output from the accelerometer when the vehicle is on level ground; and
determine an acceleration of the vehicle for identifying at least one of a location of the vehicle or a driving event involving the vehicle, the determining comprising using the orientation output to compensate an acceleration output data item received from the accelerometer based on the orientation of the accelerometer with respect to the vehicle.
