Abstract

A parking lot with a plurality of parking spaces for vehicles that have OCR-readable license numbers and onboard units with radio IDs that can be read out via radio signals. The parking lot including a central computer for storing parking space reservations, a vehicle license number and an assigned radio ID, a radio beacon for the parking spaces for reading out the radio ID of an entering vehicle via radio and signaling the radio ID to the central computer, and at least one camera unit for each parking space for reading the license number of a vehicle and correspondingly signaling the license number to the central computer. The central computer checks whether for a radio ID signaled to the central computer the vehicle license number is subsequently signaled by the camera unit of this parking space, and to log instances in which this is not the case.

Claims

1. A parking lot with a plurality of parking spaces for vehicles that have license plates with optical character recognition (OCR)-readable license numbers and onboard units with radio IDs that can be read out via radio, comprising:

a central computer for storing parking space reservations each comprising an indication of a parking space, a vehicle license number and an assigned radio ID;

a radio beacon for the parking spaces that is positioned at an entrance of the parking lot for reading out the radio ID of an entering vehicle and signaling the radio ID to the central computer; and

at least one camera unit for each parking space for reading the license number of a vehicle parked therein by OCR and signaling the license number to the central computer, wherein the central computer is configured to check whether for a given radio ID signaled to the central computer, the vehicle license number assigned thereto in a stored parking space reservation is subsequently signaled by the camera unit of said parking space, and to log instances in which said vehicle license number is not subsequently signaled by said camera unit.

2. The parking lot according to claim 1, further comprising an additional camera unit mounted at the entrance and for reading the license number of the entering vehicle by OCR and signaling the license number to the central computer, wherein the central computer is further configured to check whether a signaled radio ID and a vehicle license number signaled by the additional camera unit are assigned to one another in a parking space reservation, and to log instances in which said assigned radio ID and said vehicle license number are not signaled to one another in said parking space reservation.

3. The parking lot according to claim 1, further comprising a display panel mounted at the entrance and controlled by the central computer, wherein the central computer is configured to display, the parking space that is assigned in a parking space reservation to a radio ID signaled to the central computer, on the display panel.

4. The parking lot according to claim 1, wherein the radio beacon is a dedicated short-range communication (DSRC) radio beacon for reading out onboard units of a DSRC road toll system via radio.

5. The parking lot according to claim 1, wherein at least one parking space is equipped with an electric vehicle charging station controlled by the central computer, and wherein the central computer is further configured to unlock the charging station for charging the vehicle after successfully checking the vehicle license number signaled by the camera unit of said at least one parking space.

6. The parking lot according to claim 5, wherein the parking space reservation for said parking space contains charging parameters that are specific to the vehicle and transmitted to the charging station by the central computer.

7. The parking lot according to claim 6, wherein the charging parameters specific to the vehicle are read from the onboard unit by the radio beacon and added to the parking space reservation.

8. The parking lot according to claim 5, wherein the camera unit of said parking space is configured to record a thermal image of the vehicle during the charging process to trigger an alarm, if a temperature of the vehicle exceeds a predetermined value.

9. The parking lot according to claim 1, wherein at least one parking space is provided with a surface marking that separates the at least one parking space from other parking spaces from one another and can be monitored by its camera unit, and wherein the camera unit, in cooperation with the central computer, detects and logs instances in which the surface marking is covered by a vehicle parking thereon.

10. The parking lot according to claim 9, wherein at least two camera units are provided per parking space to jointly monitor the surface marking of the parking space.

11. The parking lot according to claim 9, wherein the surface marking is projected onto the ground by at least one lighting unit.

12. The parking lot according to claim 11, wherein the lighting unit projects a light fan onto the ground and at least one of the camera units lies outside the light fan.
