An automobile monitoring arrangement tracks and records automobile
operation for post-use automobile operation analysis and in a manner with
default-operation modes that facilitate use by automobile
owners/supervisors and by those supervised by the automobile
owners/supervisors. In one specific embodiment, a record of
automobile-operation data contains periodic recordings of speed and
direction of an automobile while it was being driven, as such data is
provided by a conventional electronic compass and the automobile's
electronic speed indicating signal. A processor performs calculations
using speed and directional data to calculate acceleration and rate of
directional change. Automobile operation data from the recording devices
and the calculations performed is compared to stored reference data to
determine if the vehicle was abused or driven in an unsafe manner by the
operator. The data is output to a display showing automobile operating
data and instances where the automobile was abused or driven in an unsafe
manner.
