An automated vehicle rental system with individual vehicle transmitting sensors
for keeping track of vehicle mileage, fill state of vehicle fuel tank, and localized
position status in a rental lot. Sensors are linked to the vehicle odometer reading
and to the vehicle fuel tank float sensor with compensation for types of driving
and fuel fill-ups which affect float level readings. The sensors are integrated
with or are linked with communicating tags operable in a defined site for ultimate
communication of stored vehicle related sensor data, vehicle location and type
to a central data base for automatically completely effecting check out, charges
and state of vehicle readiness for renewed rental. The transmitting sensors are
adapted to avoid interference between sensors of other vehicles during multiple
transmissions. Also included is an in-vehicle check out and payment device operatively
linkable to the transmitting sensor of the vehicle.
