Some companies are currently developing fully automated driving. It is clear that the technology to drive a vehicle completely automated will be implemented in the coming years. Two different business models are split into this technology: autonomous driving for end customers and autonomous driving in the context of services. Uber, for example, wants to offer their ride-hailing service with autonomous vehicles. For example, BMW could run autonomous vehicles as part of DriveNow or ReachNow. However, it is still unclear how the execution of services in autonomous driving should be technologically solved.

The link between the autonomous driving technology and the future services / "applications" building on it is a technically unsolved topic.

The AV SDK offers a "high-level" Abstraction to the functions of the vehicle, so that the security is guaranteed on a deeper level, close to the vehicle integration, such as actuators and sensors.

The system for communication of a vehicle application with a motor vehicle is divided into two parts: the application platform as a device for a vehicle application platform of a motor vehicle and the autonomous vehicle driving system as a device for a driving operation of a motor vehicle. In between, data is exchanged. The application of a third party communicates with the software of the autonomous vehicle, which exchanges data with the Main Control Unit. Thus, the third party only has access to the vehicle's software API, but not to the main control unit, so basic vehicle functions can not be changed. The transmission between the Application Platform and the Autonomous Vehicle Driving System is secure and encrypted. Both the app and the software of the autonomous vehicle can exchange data with their respective backend / cloud server. Similarly, there are Autonomous Vehicle User Interface Elements, which can also be controlled with the app via an API, such as symbols in the HUD, vehicle lighting, vehicle displays and the like.

Applications developed with the AV SDK are managed by a central server unit from the vehicle manufacturer. From the server unit, vehicle users can download and install applications developed with the AV SDK on their vehicle. The server unit only allows applications that meet certain security standards and have passed tests. This ensures that all applications are safe and serve their intended purpose.

The AV SDK may include, for example, the following functions: access to vehicle data such as speed, GPS position, position in the lane, and the like. Access to environmental detection data such as objects, lane information, and the like. "High-level" interface for driving the vehicle with commands such as "stay in lane", "stop", "turn left" and the like. Access to the Internet for the exchange of data with the server unit to exchange application-helping data. Access to User Interface Elements.

The invention can be summarized as follows:

The invention makes it possible to encapsulate the autonomous driving functions of applications which use autonomous driving as a service. Thus, it can be ensured that non-vehicle manufacturer services or Although applications can give instructions for autonomous driving to the vehicle, but without these services / applications of third-party providers and thus without the third-party providers themselves having access to the functions of autonomous driving itself and thus these functions are not modifiable. This is critical in order to make a vehicle or vehicle model available to different service providers, without that certified, verified and / or field-proven, ie "safe" autonomous driving functions can be independently modified by each service provider or adapted to its needs, which is expected to be a high frequency of errors of autonomous driving functions and thus lead to high accident rates and thus would run counter to the acceptance and meaningfulness of autonomous driving. By encapsulating the autonomous driving functions, however, it is still possible to respond to the needs of service providers or service providers without having to modify autonomous driving functions that are considered to be safe. Further, service providers to provide their services based on autonomous driving need not be experts in autonomous driving functions. The service provider can therefore specify what the autonomously operated vehicle should do, such as "turn off at the traffic light", while the autonomously driving motor vehicle independently implements this instruction by its rules or the autonomous driving functions, the instruction or parts of it as a parameter. Thus, the motor vehicle continues to decide independently when it drives over the traffic lights, as it turns right and how it accelerates again, if necessary. However, the service provider may indicate, for example, that currently fragile goods are transported in the autonomous motor vehicle, which autonomously determines the autonomous motor vehicle, as it must accelerate carefully.

This is achieved by providing an on-board device which receives the instructions of a vehicle-external device and, according to its own state model, implements the vehicle or the autonomous driving functions in a regular manner. The service provider is provided with the vehicle-external device on which he can develop his applications and can provide his services based on autonomous driving functions or use these to a corresponding motor vehicle, without having to know or even modify the autonomous driving functions of the motor vehicle. An external certification body, which may for example be an authority or the vehicle manufacturer itself, can provide the vehicle-external device with a corresponding certificate in order to ensure that the services which use the autonomous driving functions of the motor vehicle are allowed to do so. The communication between the vehicle-foreign and the vehicle's own device can be secured, for example by means of suitable encryption.

Thus, therefore, a kind of "operating system" for autonomously driving motor vehicles are provided so that not every user / service provider has to develop his own autonomous motor vehicle, but only his required for the motor vehicle application. Such an application may be, for example, that of a parcel service provider.

A fully developed motor vehicle can thereby be used for various applications versatile, while maintaining the developed or used by the vehicle manufacturer safe autonomous driving functions.

By encapsulating the driving functions of the motor vehicle, the liability can be more easily clarified. As a result, standardized communication of an application with the motor vehicle allows autonomous driving even when using services of such applications. A certification authority can issue a certificate which enables the application to communicate with the motor vehicle via the application interface. The security of the applications can be ensured by checking them by the certification authority.
