Abstract

In a method and an apparatus for finding an available parking lot, when information about an available parking lot is requested, a locating system first determines the current motor vehicle position, and finds the possible parking lots in a search area on the basis of this position. The data about parking lots are preferably transmitted using the TMC channel of the Radio Data System (RDS). If there are several cities in the search area, then a corresponding selection for a city can be made using an input device. Furthermore, districts with parking lots located in these districts can be selected, in order to find a parking lot as close to the destination as possible. In the case of P+R lots, the connections to the public transit system are also output, along with additional information, for example the train frequency. The apparatus is integrated into a car radio, so that the receiver part, input device, and displays of the car radio can be utilized.

Claims

1. A method for locating at least one available parking facility for a motor vehicle, comprising the steps of:

requesting parking data corresponding to the at least one available parking facility;

determining a current position of the motor vehicle using a locating system when the parking data is requested;

receiving the parking data related to the at least one available parking facility corresponding to at least one assigned town code;

predetermining a search area corresponding to the current vehicle position;

selecting the at least one assigned town code of at least one town positioned in the search area;

at least one of optically outputting and acoustically outputting at least one town name corresponding to the at least one selected town code;

selectively choosing at least one of a destination area and a district from the at least one town name using an input device, the destination area being divided into predetermined districts, the input device including a key arrangement, each of the districts being assigned to a key of the key arrangement, the key arrangement being associated with a geographical location of the districts;

selecting at least one message associated with the at least one available parking facility for the selected district; and

outputting at least one of the at least one available parking facility corresponding to the at least one message.

2. The method according to claim 1, wherein the step of receiving the parking data is performed using a Radio Data System.

3. The method according to claim 2, further comprising the step of:

receiving RDS data from the Radio Data System, wherein the at least one message is selected from the RDS data.

4. The method according to claim 1, wherein the at least one available parking facility corresponds to the selected district, and further comprising the step of:

automatically displaying the at least one available parking facility corresponding to the selected district.

5. The method according to claim 1, further comprising the step of:

assigning pathways of a public transit system to the selected district for outputting the pathways.

6. The method according to claim 5, wherein the pathways of the public transit system include schedules.

7. The method according to claim 5, further comprising the step of:

outputting the pathways of the public transit system and the at least one available parking facility on an electronic street map.

8. The method according to claim 1, wherein each of the at least one town has a corresponding assigned commuter area, and further comprising the step of:

selecting at least one available parking facility assigned to one of the at least one town if the current vehicle position is substantially in the commuter area.

9. An apparatus for locating at least one available parking facility for a motor vehicle, comprising:

a Radio Data System (RDS) transmitting RDS data and including an RDS receiver;

a message memory for storing at least one assigned town code corresponding to at least one town and for storing messages corresponding to the at least one available parking facility;

an input device including input keys and selecting at least one of a destination area and at least one district from the at least one assigned town code, the input keys of the input device being arranged as one of a key pad and a rocker key and being assigned to predetermined districts, the input keys including top keys, bottom keys and at least one further key;

a data output device receiving at least one assigned town code and outputting at least one town name corresponding to the at least one assigned town code;

a locating system determining a current position of the motor vehicle; and

a controller connected to the locating system and selecting the at least one assigned town code corresponding to assigned data of the at least one available parking facility in the destination area using the RDS data,

wherein the top keys correspond to northern districts of the predetermined districts, and the bottom keys correspond to southern districts of the predetermined districts, and

wherein the at least one further key selects the destination area and requests a search for locating the at least one available parking facility.

10. The apparatus according to claim 9, wherein the Radio Data System includes a Traffic Message Channel (TMC) having a data protocol for selectively transmitting the assigned data of the at least one available parking facilities.

11. The apparatus according to claim 9, wherein the key pad includes at least one of a 9-key pad, a 10-key pad and a 16-key pad.

12. The apparatus according to claims 9, wherein the districts have a high resolution output obtained by one of repeatedly pressing one of the input keys of the input device and pressing one of the input keys at various times.

13. The apparatus according claim 9, wherein the apparatus is connected to one of a navigation guidance system and a destination guidance system for indicating a travel route to the at least one available parking facility having a location closest to a desired destination.
