A shared vehicle system includes a central facility, at least one vehicle distribution
port facility and a plurality or fleet of vehicles, each having a vehicle subsystem.
In general, the central station and port facility and the vehicle subsystems communicate
in a manner to allow a user to enter information at a port facility. That information
is then communicated to the central facility, where the information is processed
to select a vehicle from the fleet to allocate to the user at the port facility.
Selection of a vehicle for allocation to a user may be based on selecting an available
or soon to be available vehicle according to various algorithms that take into
account the vehicles state of charge. The central station also communicates with
the port facility and the vehicle subsystem to notify the user of the selected
vehicle, to provide secure user access to the selected vehicle, to monitor the
location and operating status of vehicles in the fleet, to monitor the state of
charge of electric vehicles and to provide other functions. The vehicles communicate
with the central station to notify the central station of the PIN number of the
individual attempting to use the vehicle, and of vehicle parameters such as state
of charge and location of the vehicle.
