Patent Images
1. A system for elucidating ghost trips in a fleet of vehicles, the system comprising:
- a plurality of vehicles each equipped with a movement detector for detecting movements of the vehicle and a recorder for recording detected movements of the vehicle and recording driver login and logout events; and
a server comprising a processor and one or more non-transient computer readable media storing computer readable instructions, which, when processed by the processor, cause the processor to;
receive, from one of said recorders in one of said vehicles, data representing a period of unauthorized movement of said one vehicle;
determine durations for which each of a plurality of drivers were not logged into any of the vehicles;
determine whether any of the durations include the period of unauthorized movement; and
if one or more of the durations includes the period of unauthorized use, assign to each driver to which said one or more durations correspond, a likelihood of being responsible for the unauthorized movement.

Abstract
Unauthorized use of fleet vehicles is detected by matching drivers'"'"' logged out times with vehicle movements for which there is no logged in driver. Allowance is made for vehicles that may be moved within permitted areas without a logged in driver. A likelihood value is assigned to each candidate driver whose logged out time corresponds to the duration of unauthorized movement of the vehicle. The likelihood value is increased if the candidate driver is the next driver to log into the vehicle after its unauthorized usage.
