In a system with which more vehicle doors/flaps can be opened and closed than the radio key has buttons, the area around the vehicle (3) is divided into several local locating areas (A, B, C, D) with different ranges (29, 31), whereby depending on the position of the radio key (17) in the local locating areas (A, B, C, D) by pressing the same button (15) on the radio key (17), different vehicle doors/flaps (7, 9) are to be opened.

Description

The invention relates to a system for opening and/or closing a vehicle door/flap, comprising a radio key and at least one transmitter/receiver unit arranged on the vehicle, a tailgate of the vehicle being opened when a specified button on the radio key and radio key is actuated and the transmitter/receiver unit are located within a localization range characterized by a predetermined distance from one another.

From the DE 10 2017 115 816 A1 a system with a door, door lock and radio key is known, the door lock having a door control module which has a transceiver on the door, and a key which is assigned to the door lock and which is assigned to a transceiver on the key. The two transmitter/receiver units communicate wirelessly via a radio link. The door lock is only opened when a predetermined first button of the key is pressed and the key is within a predetermined distance from the transceiver on the door. To close the door lock, a second button on the key must be pressed when the key is within range of the transceiver on the door. A third button on the key is required to open a tailgate of the vehicle.

The object of the invention is to specify a system for opening and/or closing a vehicle door/flap, with which more vehicle doors/flaps can be opened and closed than the key has buttons.

The invention results from the features of the independent claims. Advantageous developments and refinements are the subject matter of the dependent claims. Further features, application possibilities and advantages of the invention result from the following description and the explanation of exemplary embodiments of the invention, which are shown in the figure.

The object is achieved with the subject matter of patent claim 1.

In the initially explained system for opening and/or closing a vehicle door/flap, comprising a radio key and at least one transmitter/receiver unit arranged on the vehicle, a tailgate of the vehicle being opened when a predetermined button of the radio key and radio key is actuated and the transmitter/receiver unit are within a locating area characterized by a predetermined distance from one another, the area around the vehicle is divided into several local locating areas with different ranges, with different ones depending on the position of the radio key in the local locating areas by pressing the same button on the radio key Vehicle doors/flaps can be opened. This has the advantage that the number of buttons on the radio key can be minimized, which reduces the costs and the geometric design of the radio key. The radio key can thus be given a more attractive design.

The local locating range is advantageously specified by a range of the respective transmitter/receiver unit. Since the local locating areas have different ranges, an opening or closing process of a vehicle door/flap can be determined simply by positioning the key in the respective locating area.

In one embodiment, the local locating areas are formed by dividing the perimeter of the vehicle into segments, with each local locating area having at least two radial areas with different ranges. This increases the number of vehicle doors or hatches that can be opened or closed by actuating just a single button.

In one variant, a first transmitter/receiver unit generates a locating range starting from a tailgate behind the vehicle and a second transmitter/receiver unit generates another locating range starting from a front flap of the vehicle in front of the vehicle, with the locking systems of the tailgate or the front flap being activated by pressing the same button of the radio key depending on whether the radio key is in front of or behind the vehicle. In this case, the same ranges only have to be designed in different vehicle directions, which reduces the design effort for the transmitter and receiver units. The vehicle door/flap to be opened or closed is identified simply by the position of the radio key.

In one embodiment, the front flap closes an additional storage space in the electrically powered vehicle. This additional storage space is gained because no internal combustion engine is included in the vehicle. This means that the tailgate and front flap can be operated with just one mechanical button on the radio key.

Further advantages, features and details result from the following description, in which at least one exemplary embodiment is described in detail-if necessary with reference to the drawing. Described and/or illustrated features can form the subject of the invention on their own or in any meaningful combination, possibly also independently of the claims, and in particular can also be the subject of one or more separate applications. Identical, similar and/or functionally identical parts are provided with the same reference symbols.

It shows:

• 1 an embodiment of the system according to the invention.

In 1 an embodiment of the system according to the invention is shown. The system 1 includes a vehicle 3 whose doors 5 or flaps 7, 9 can be unlocked or locked by actuating mechanical buttons 11, 13, 15 of a radio key 17. When the button 11 is actuated, all of the vehicle doors 5 connected via a central locking system are unlocked. When the button 13 is pressed, the vehicle doors 5 are locked. The tailgate 7 or the front flap 9 are unlocked by means of the button 15 . A transmitter/receiver unit 19 of radio key 17 communicates via a radio link with a transmitter/receiver unit 21, which is positioned on the rear side of vehicle 3, and with a second transmitter/receiver unit 23, which is arranged on the front side of vehicle 3 . In addition, a further transmitter/receiver unit 25, 27 for unlocking and locking the vehicle doors 5 is placed on each longitudinal side of the vehicle 3.

Each of the transmitter/receiver units 21, 23, 25, 27 spans two ranges in the segment A, B, C, D covered by the respective transmitter/receiver unit 21, 23, 25, 27, which extend in a circular ring around the vehicle and thus surround the entire vehicle 3 . The range 29 includes a distance of, for example, less than 3 m from the vehicle 3, while the second range 31 connects to the first range 29 and covers a range of, for example, 3 to 6 m.

If the tailgate 7 of the vehicle 3 is to be opened, the user must position himself with the radio key 17 in segment A within the range 29 and press the button 15 . The front flap 9 of the vehicle 3 is opened when the user is in segment B within range 29 with the radio key 17 and also presses the button 15 . The vehicle doors 5 on the side of the vehicle 3 are opened when the user with the radio key 17 is within range 29 in segments C or D and presses the button 11 . If the user presses button 13 of radio key 17 and is within range 31 of segments C or D, vehicle doors 5 are closed via the central locking system.
