Abstract

A parking control system in which a mobile telephone is used to commence and to terminate parking of a vehicle within a parking zone. A parking system user sends a user-specific code to a parking system computer at the commencement of and at the termination of a parking period. A vehicle-specific code corresponding with the parked vehicle is stored in the computer upon commencement of a parking period. A portable parking control unit can read the vehicle-specific code from a parked vehicle and can establish communication with the parking system computer, which is informed of the parking zone concerned. When the control unit requests information concerning vehicles parked within a particular parking zone, the computer sends corresponding information relating to one or more additional parking zones that are geographically close to the parking zone in question.

Claims

1. A parking control system in which a mobile telephone can be used to commence and terminate a parking period for a vehicle, wherein a user sends at least one user-specific code to a parking system computer belonging to said parking system at the commencement and termination of a parking period through the medium of a telephone system, wherein the parking system is informed of the parking zone concerned at the commencement of a parking period, wherein a machine-readable vehicle-specific code is stored in said computer and tied to the user-specific code, the parking control system comprising:

a portable control unit including a reader to read a vehicle-specific code carried by the vehicle and to establish wireless communication with the parking system computer and retrieve information from the parking system computer concerning vehicle identification for vehicles that have commenced but not terminated parking within the parking zone concerned, wherein the parking system computer transmits to the control unit corresponding parked vehicle identification information relating to vehicles parked in at least one additional parking zone that is geographically close to the parking zone concerned at the same time as it sends the requested information to said control unit for the parking zone concerned.

2. A parking control system according to claim 1, wherein the control unit reads a vehicle-specific code and compares the code with the information received from the parking system computer and stored in the control unit and the read vehicle-specific code is not included in the information received from the parking system computer the computer checks whether or not the read code is stored in respect of a vehicle parked in another parking zone, and the parking system computer sends to the control unit information relating to vehicles parked in the at least one additional parking zone.

3. A parking control system according to claim 1, wherein the control unit compares the read vehicle-specific code with the information stored in the control unit and sends the code to said parking system computer when the read code is not found in the stored informnation;

wherein the computer checks whether or not the read code has been stored in respect of a vehicle parked in another parking zone and to send to the control unit a signal indicating that the vehicle concerned has not been reported to the system as being parked, and wherein the control unit provides a signal to indicate that the vehicle has not been reported as being parked.

4. A parking control system according to claim 3, wherein when a vehicle has been parked for less than a given predetermined time period, the control unit stores the vehicle-specific code together with the time at which the code was read and provides a signal when said predetermined time period has expired.

5. A parking control system according to claim 3, wherein when a vehicle has been parked for a given predetermined time period within a particular parking zone, the control unit stores the vehicle-specific code together with the time at which the code was read and communicates with said parking system computer and retrieves a current list of parked vehicles when said predetermined time period has expired.

6. A parking control system according to claim 1, wherein when a vehicle-specific code is read, the control unit compares said code with the parking information stored in said control unit and, when the code is found sends a signal to the control unit indicating that the vehicle whose vehicle-specific code has been read is correctly parked.

7. A parking control system according to claim 1, wherein said information relating to the at least one parking zone geographically close to the parking zone concerned includes a part of an area monitored by a parking attendant.

8. A parking control system according to claim 1, wherein the telephone system is a mobile telephone system.

9. A parking control system according to claim 1, wherein the telephone system is a public switched telephone system.

10. A method of controlling parking in a parking system having a plurality of parking zones and having a parking system computer that is adapted to store parking-system user, vehicle, and parking time information and to communicate with a portable parking control unit carried by a parking attendant, said method comprising the steps of:

a) communicating by a parking system user to the parking system computer upon commencement of a parking period a user-specific code, a vehicle-specific code, and a specific parking zone identifier;

b) reading the vehicle-specific code with the portable control unit carried by the parking attendant and transmitting the read vehicle-specific code to the parking system computer along with the specific parking zone identifier; and

c) transmitting from the parking system computer to the portable control unit carried by the parking attendant vehicle identification information relating to vehicles that have properly commenced a parking period within the specific parking zone and within additional parking zones geographically close to the specific parking zone to enable the parking attendant to verify that a particular vehicle had properly commenced a parking period within the parking system.

11. A method according to claim 10, wherein the vehicle-specific code is carried by the vehicle and is readable externally of the vehicle.

12. A method according to claim 10, wherein the parking zone identifier for a particular parking zone is a specific telephone number associated with the particular parking zone.

13. A method according to claim 10, wherein the communication is effected over a telephone network.

14. A method according to claim 13, wherein the telephone network is a mobile telephone network.

15. A method according to claim 10, wherein the vehicle-specific code is a vehicle registration number.

16. A method according to claim 10, including the step of comparing the sensed vehicle-specific code with parked-vehicle information stored in the parking system computer.

17. A method according to claim 16, wherein the parked-vehicle information includes information relating to vehicles parked for less than a predetermined time period, and including the step of transmitting a signal to the portable control unit when the predetermined time period has expired.

18. A method in accordance with claim 16, including the step of transmitting a signal from the parking system computer to the portable control unit when the sensed vehicle-specific code corresponds with that of a properly parked vehicle.
