Description of embodiments

In the following, the term "automated motor vehicle" is used interchangeably in the meanings partially automated motor vehicle, autonomous motor vehicle and partially autonomous motor vehicle.

A central idea of the invention is to provide a method with which a motor vehicle can log on to an infrastructure in a secure manner. This should make it possible that unauthorized motor vehicles should not be given access to the infrastructure. In this way, only authorized motor vehicles (for example, regular tenants of parking spaces of a parking garage) can enter the infrastructure, which advantageously increases a general level of safety of defined driving areas.

The following is based on 1 an operation of an exemplary embodiment of the method according to the invention explained.

You can see an infrastructure 100 , For example in the form of a parking garage, premises, open space with security access, road section with security access, etc. in a motor vehicle 30 wants to enter and for this purpose in the infrastructure 100 log in or authenticate to it. For this purpose, when approaching the motor vehicle 30 to the infrastructure 100 from a signaling device 10 , For example, in the form of an electronic computing device generates a first coded signal S1, which via a line 12 electrically wired to a first transmission device 20 is transmitted.

The first transmission device 20 is designed as an LED or as an infrared device that is capable of the first coded signal S1 wirelessly to the motor vehicle 30 to transmit or to send. The encoded first signal S1 is preferably by a defined chronological sequence of inputs and Auszuständen the first transmission device 20 generated. The infrared device has the advantage that radiation emitted by it is not seen by the human eye, from the first receiving device 31 of the motor vehicle 30 however, it is detected.

By means of a motor vehicle 30 arranged first receiving device 31 For example, which is formed as a camera, for example, will receive the first coded signal S1.

Thereafter, by means of an evaluation device (not shown), in the first receiving device 31 arranged or optionally separated from this in the motor vehicle 30 is arranged, the first coded signal S1 evaluated or verified.

Upon successful or valid verification of the first coded signal S1 by the motor vehicle 30 is subsequently from the motor vehicle 30 a second coded signal S2 by means of a second transmission device 32 transmitted or transmitted wirelessly, wherein a code of the second coded signal S2 is assigned to the code of the first coded signal S1 defined.

The second transmission device 32 can be designed as at least one LED of a motor vehicle headlight or as an additional or alternative to the motor vehicle 30 arranged LED. Alternatively or additionally, the second transmission device 32 as an infrared device of the motor vehicle 30 be educated. A trained as an infrared device second transmission device 32 has the advantage that radiation emitted by it is not seen by the human eye, from the second receiving device 11 the infrastructure 100 however, it is detected.

From a second receiving device 11 the infrastructure 100 For example, which is formed as a camera, for example, that of the second transmission device 32 of the motor vehicle 30 emitted second coded signal S2 received and via a line 13 to the signaling device 10 forwarded. From the signaling device 10 the received second coded signal S2 is evaluated or verified. In the event that the transmitted second coded signal S2 has a valid format, ie has been verified correctly, the motor vehicle is authenticated 30 such that the motor vehicle 30 for the infrastructure 100 is allowed.

For example, it may subsequently be provided that a barrier to the infrastructure 100 is opened so that the motor vehicle 30 into the infrastructure 100 can retract.

For example, it can be provided subsequently that the motor vehicle 30 in the event that it is an automated motor vehicle, through the infrastructure 100 is controlled, for example, a control of the motor vehicle 30 within a parking garage is taken to a parking lot. For this purpose, provision may be made for suitable control commands to be sent to a vehicle actuator of the motor vehicle via suitable wireless communication technologies, such as WLAN, mobile radio, etc. 30 be sent.

Optionally, it may be provided that the coded signals S1, S2 are connected to e.g. acyclically and / or acted upon after defined periods of changing codes, thereby a safety level can be increased significantly for the proposed method.

Advantageously, the method according to the invention can be implemented as software that is based on the signal device 10 , the evaluation device of the motor vehicle 30 and / or an external computer device expires. A simple adaptability of the method is supported in this way. As an alternative embodiment of the method is also conceivable that the coded signals S1, S2 are formed as radio signals, the signal from the device 10 generated and from suitable transmission facilities 20 . 32 , For example, in the form of radio transmitters and sent by suitable receiving equipment 31 . 11 , eg in the form of radio receivers.

2 shows a basic sequence of an embodiment of the method according to the invention.

In one step 200 is a by means of a signaling device 10 generates a first coded signal S1.

In one step 210 is a wireless transmission of the first coded signal S1 by means of a first transmission device 20 to the motor vehicle 30 carried out.

In one step 220 is the first coded signal S1 by means of one on the motor vehicle 30 arranged first receiving device 31 received and verified.

In one step 230 is in the case that the first coded signal S1 from the motor vehicle 30 has been successfully verified, a wireless transmission of a second coded signal S2 by means of one on the motor vehicle 30 arranged second transmission device 32 to a second receiving device 11 carried out.

In one step 240 is the second coded signal S2 by means of the second receiving device 11 receive.

In one step 250 is the second coded signal S2 by means of the signaling device 10 Verified.

Finally, in one step 260 in the event that the second coded signal S2 has been validly verified, the motor vehicle 30 authenticated.

In summary, the present invention proposes a method and a device for authenticating a motor vehicle. For this purpose, radiation or light signals coded between the infrastructure and the motor vehicle are transmitted bidirectionally, thereby providing access control with a high degree of security. Advantageously, the explained authentication process for secure authentication must be performed only once.

One skilled in the art will suitably modify and / or combine the features of the invention without departing from the gist of the invention.
