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.
