The system also includes a module for presenting instructions in augmented reality that, when executed, initiates a display of the augmented reality walking instructions in real-time from the current user location toward the pick-up location of a vehicle.

The invention has for its object to provide a comparison with the prior art improved method for supporting a vehicle user to find a reserved, autonomously driving vehicle and a vehicle with a device for performing the method.

The object is achieved with respect to the method by the in claim 1 and with respect to the vehicle by the features specified in claim 2.

Advantageous embodiments of the invention are the subject of the dependent claims.

A method for assisting a passenger to find a reserved, autonomously driving vehicle, which can also park, according to the invention provides that the vehicle has a detection unit for detecting the face of the passenger is detected and the detected face with a Social Media profile image and / or with an image that was taken in a previous trip of the passenger with the vehicle is compared and / or the passenger is detected via a communication connection based on his mobile device and / or the vehicle a location signal to a central processing unit is sent and a total overview of vehicles in a given area on the mobile terminal is displayed and / or a location of the vehicle is determined by stationary obstacles and / or based on odometry data, wherein a passenger position and a location of the vehicle are compared, u m to navigate the passenger by means of his mobile device to the vehicle, which upon reaching the vehicle this and / or its representation is marked on the mobile terminal.

By applying the method, the autonomously driving vehicle assigned to the passenger, in particular the autonomous vehicle reserved for the passenger, which has a shuttle, ie. H. a vehicle for so-called point-to-point traffic is found to be essentially trouble-free.

By means of the method, the vehicle can also be found when the vehicle is located in an area in which a location determination of the vehicle by means of a satellite-based position determination unit is not possible.

The vehicle can be found relatively easy, with the passenger feels perfectly supported in his search for the right vehicle. The vehicle is directly assigned, so that a check-in can be carried out quickly and possibly a reorganization of a shuttle service is possible if a distance between the passenger and the vehicle is comparatively large.

Embodiments of the invention will be explained in more detail below with reference to a drawing.

• 1 schematisch einen Fahrgast mit einem mobilen Endgerät und ein autonom fahrendes Fahrzeug.

It shows:

• 1 schematically a passenger with a mobile terminal and an autonomously driving vehicle.

In the single figure are a passenger 1 with a mobile device 2 in the form of a smartphone in his hand and an autonomous vehicle 3 shown.

In the future will be increasingly autonomous driving vehicle 3 for a point-to-point traffic, called shuttle, passengers 1 to their respective destination. To use such a vehicle 3 becomes the passenger 1 often ordered at an agreed meeting point and / or to a stop. Especially in areas with a relatively high customer frequency, z. B. at a train station or an airport, as a place of entry may be for a passenger 1 difficult to design the right autonomous vehicle 3 find.

Such an autonomously driving vehicle 3 is typically due to route guidance to the passenger 1 assigned to each transport a group of passengers in the direction of a same destination.

For example, entry-level locations are partially underground, covered and / or in parking garages, so that a satellite-supported position determination by means of a position determination unit, not shown, of the vehicle 3 is significantly restricted, causing the passenger 1 with his mobile device 2 on which an application program for reserving and locating the vehicle 3 saved, not so easy to the vehicle 3 can be navigated. There is the problem that a precise location of the vehicle 3 and an exact passenger position can not be determined.

Furthermore, the problem is the right vehicle 3 among a variety of possibly identical-looking vehicles 2 to detect.

In addition, such is used as a shuttle autonomously driving vehicle 3 Compared to a bus much smaller, with scoreboards on the vehicle 3 are also correspondingly smaller and thus a display is limited.

To the passenger 1 finding his assigned autonomous vehicle 3 To support, a method described below is provided.
The autonomously driving vehicle 3 has a comparatively extensive sensor technology, wherein at least one detection unit as a camera 4 is executed.

According to the assumption of a multitude of waiting, approaching and departing vehicles with respect to the entry point 3 to passengers 1 getting in and out, the chance is relatively large that the sensors, in particular the camera 4 of a vehicle 3 or more of such autonomous vehicles 3 the passenger 1 capture and this by means of a processing unit of the respective vehicle 3 performed evaluation of detected image signals is detected. For this purpose, a method of facial recognition is used, with a picture of the passenger 1 as comparison template in the vehicle 1 is available. So there will be biometric data of the passenger 1 compared.

For example, the picture will be a social media profile picture. When registering with a service for the use of such an autonomously driving vehicle 3 can z. For example, a social media account may be used such that this social media profile image is present, and it may also be provided that the vehicle 3 posted on this social media, so ordered, can be.

Alternatively or additionally, it is possible that during a previous journey of the passenger 1 with such an autonomously driving vehicle 3 a picture of the passenger 1 by means of a vehicle outside and / or vehicle inside arranged camera 4 a picture was taken. When getting into the vehicle 3 and thus a use of the same is unique and the passenger 1 about so-called person tracking the vehicle 3 can be assigned clearly, can by means of a vehicle-mounted camera 4 taken picture as reference template for a next use of the service can be used.

Alternatively or additionally, the method provides assistance to the passenger 1 before, that network properties of the mobile terminal 2 , for example, the smartphone, the passenger 1 be used.

Usually, WLAN is on the mobile device 2 activated and the same searches for a network and / or at least an interface of the mobile terminal 2 to set up a radio link is activated, looking for other devices to establish a radio connection. It is also conceivable that, alternatively or additionally, a further component for near-field communication of the mobile terminal 2 is activated with a corresponding further device.

The mobile device 2 and thus the passenger 1 are transmitted via the mobile device 2 detected radio signals detected. For example, the recognition via the application program of the service, via typical radio signals and / or unique signatures of the transmitted radio signals. By means of a signal strength of the transmitted radio signals, a distance between the passenger 1 and the vehicle 3 be determined.

It is also conceivable that the vehicle location and / or the passenger position can be determined more accurately via a plurality of antennas and, if the vehicle location and the passenger position agree, at least one vehicle door of the vehicle 3 automatically opens, leaving the passenger 1 can get started immediately.

Be the radio signals and / or data of the application program of several such autonomously driving vehicles 3 receive or these have installed a plurality of receivers, a much more accurate positioning is possible via a triangulation.

Again alternatively or additionally, it may be provided that the autonomously driving vehicle 3 its position and identification number to other autonomous vehicles 3 the service and / or to a central computer unit 5 sends. The central computer unit 5 then sends an overview of autonomous vehicles 3 in a given area.

For example, the passenger becomes 1 on the basis of detected image signals of one of the autonomously driving vehicles 3 recognized, even if another autonomous driving vehicle 3 for the passenger 1 is reserved. Based on the known vehicle locations of existing in the given area autonomous vehicles 3 can then be a navigation of the passenger 1 to his reserved autonomously driving vehicle 3 be performed.

By means of the sensors of the autonomously driving vehicles 3 and / or by means of network components can thus be a location of the vehicle 3 as well as the passenger position.
If an autonomous vehicle 3 enters a hall, for example, in an underground bus station, there is the problem that the location of the autonomously moving vehicle 3 can not be determined by means of satellite-based position determination. To a relatively accurate determination of the location of the autonomously driving vehicle 3 Nevertheless, stationary obstacles and / or odometry data are used. For example, this can be a driven distance and signals of the sensor with respect to locations of other autonomously driving vehicles 3 be used, thereby assigning the locations to individual autonomous vehicles 3 is possible.

By combining the location of the autonomously driving vehicle 3 and the passenger position can be the passenger 1 a vehicle driving autonomously to its reserved vehicle 3 , in particular by means of the mobile terminal 2 , are displayed. So can the passenger 1 for example, a series of autonomous vehicles driving one behind the other 3 are displayed. It can be z. As well as the identification number, ie a vehicle number, the respective autonomously driving vehicle 3 displayed, wherein the reserved autonomously driving vehicle 3 highlighted, ie marked, is displayed. Approaching the passenger 1 the autonomously driving vehicle 3 can be provided that this activates its direction indicator and / or that a symbol is displayed on a display panel, so that the finding is facilitated.

The passenger 1 So receives a confirmation that he is the right, ie the reserved, autonomously driving vehicle 3 runs, this being highlighted by color, a flashing signal and / or in other ways.

To several passengers 1 at the same time in relation to the autonomous vehicle 3 to be able to inform, light signals in the direction of the respective passenger 1 or the respective passengers 1 be issued.

Is determined that the passenger 1 to an unreserved and therefore wrong autonomous driving vehicle 3 can this, a symbol for wrong or a corresponding direction information regarding the reserved autonomously driving vehicle 3 are displayed. For example, the unreserved gives a light signal and / or symbol for wrong and the reserved autonomously driving vehicle 3 a corresponding light signal and / or symbol for correct.
