Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) Further advantageous designs of the invention are disclosed in the subclaims and in the following description of the figure, wherein:

(2) FIG. 1 shows a schematic view of an example embodiment of a motor vehicle according to the invention, and

(3) FIG. 2 shows a flow diagram of an example embodiment of a method according to the invention.

DETAILED DESCRIPTION

(4) FIG. 1 shows a schematic view of an example embodiment of a motor vehicle 1 according to the invention having a device 2 permanently integrated into at least one structure (not shown) of the motor vehicle 1 for displaying a parking duration and/or a parking start of the motor vehicle 1.

(5) The device 2 is formed by an electrical display device 3 of the motor vehicle 1 which is arranged in the interior 4 of the motor vehicle 1. The electrical display device 3 is a head-up display having an imaging unit 5 arranged on a dashboard (not shown) of the motor vehicle 1 and a projection surface 7 arranged on a windshield 6 of the motor vehicle. The head-up display can use, for example, a back projection technology here.

(6) Alternatively, the device 2 can be formed at least partially by at least one electrical lighting unit (not shown) of the motor vehicle 1 which is arranged on the outside of the motor vehicle 1 and is configured for the alphanumeric display of the parking duration and/or the parking start. The electrical lighting unit can have organic light-emitting diodes.

(7) The motor vehicle 1 further has an electronic evaluation system 8 which is configured to receive position data relating to the current position of the motor vehicle 1, to determine, taking account of the position data, whether the parked motor vehicle 1 is parked in an area in which the display of the parking duration and/or the parking start is/are required, and to display the parking duration and/or the parking start automatically or at the instigation of a user via a man-machine interface of the motor vehicle 1 if the parked motor vehicle 1 is parked in an area in which the display of the parking duration and/or the parking start is/are required.

(8) The electronic evaluation system 8 is configured to determine a cost-free parking time and/or a maximum permitted parking duration if the parked motor vehicle 1 is parked in an area in which the display of the parking duration and/or the parking start is/are required, and to indicate the cost-free parking time and/or the maximum permitted parking duration in a passenger compartment or the interior 4 of the motor vehicle 1.

(9) The electronic evaluation system 8 is further configured for wireless communication with an automatic parking charge billing system (not shown). The electronic evaluation system 8 is configured to initiate parking charge billing automatically or at the instigation of a user via a man-machine interface (not shown) of the motor vehicle 1.

(10) As can be seen in FIG. 1, the light beams indicated by arrows 9 pass through the windshield 6 so that the light emitted by the imaging unit 5 is detectable from outside the motor vehicle 1 in order to display the parking duration or parking start.

(11) FIG. 2 shows a flow diagram of an example embodiment of a method according to the invention for displaying a parking duration and/or a parking start of a motor vehicle.

(12) In method step 10, the motor vehicle is driven into an area in which the display of the parking duration and/or the parking start is/are required. In method step 20, the drive of the motor vehicle is switched off. In method step 30, a motor vehicle user activates a display function via a man-machine interface to display a parking duration and/or a parking start of the motor vehicle. In method step 30, the motor vehicle user can be asked in advance whether he wishes or does not wish to activate the display function for this purpose.

(13) In method step 40, a drive control unit of the motor vehicle transmits a drive off signal to a device permanently integrated into at least one structure of the motor vehicle for displaying a parking duration and/or a parking start. In method step 50, the motor vehicle user opens a vehicle door, gets out of the motor vehicle and closes the motor vehicle door once more. In method step 60, a door sensor of the motor vehicle transmits a door closed signal to the device. In method step 70, the motor vehicle user locks the motor vehicle doors. In method step 80, the door sensor transmits a door locked signal to the device. It is determined from these signals that the motor vehicle is in a parking state.

(14) In method step 90, position data relating to the current position of the motor vehicle are received automatically. Taking account of the received position data, it is determined electronically whether the parked motor vehicle is parked in an area in which the display of the parking duration and/or the parking start is/are required. The parking duration and/or the parking start is/are therefore displayed by means of the device. The device can be designed at least partially as a head-up display. Alternatively, the device can be formed at least partially as an electrical lighting unit of the motor vehicle which is arranged on the outside of the motor vehicle and is configured for the alphanumeric display of the parking duration and/or the parking start.

(15) In method step 90, parking charge billing is further initiated automatically via an automatic parking charge billing system, wherein the parking duration resulting therefrom is displayed in a controllable manner via the device 2 for displaying a parking duration and/or a parking start of the motor vehicle 1.
