Patent ID: 7619542

Claim:
A system for estimating the location of vehicles in parking lots, having: reading means configured to read and record first data A associated with the license plate of a vehicle accessing the inside a parking lot; and detection means configured to record, through a plurality of sensors, second data B indicating a change of availability status, selecting from free and occupied, of the parking lot spaces; in which the reading means, through a plurality of control points, capture at least the following information corresponding to data A: location of the control point, license plate number of the vehicle, exact date and time of this capture; in which the detection means record at least the following information, corresponding to data B: space number, the availability status of the spaces, exact date and time in which a vehicle has parked in the space; in which the system comprises: input means configured to manually enter a license plate number corresponding to a vehicle to be located inside a parking lot, location means configured to locate the vehicle inside the parking lot, output means configured to generate a report; the reading means, detection means and location means being operatively related such that by making use of the previously recorded information through: the input means, a first receiver configured to receive data A, and a second receiver configured to receive data B; the location means can determine, by means of a control mechanism, a list of possible spaces in which the vehicle may be located inside the parking lot, wherein the control mechanism is configured to establish the list of possible spaces by means of a probability calculation.
