Description

28 01 25 FIELD OF THE INVENTION

[0001] The invention relates to the field of automobiles. More specifically, the present invention relates to a communication system according to claim 1. Furthermore, the present invention relates to a method, a corresponding computer program product, and a corresponding non-transitory computer-readable storage medium. BACKGROUND INFORMATION

[0002] The communication system for a vehicle fleet enables direct, wireless communication between the vehicles (V2X) in a defined group without the need for external devices or third-party apps.

[0003] In the prior art, communication systems are primarily used for safety-related applications, where data is exchanged between vehicles (V2V) or with the infrastructure (V2X) to improve road safety. However, these solutions do not focus on a personal and individual communication within a closed group of vehicles without external devices.

[0004] The prior art in DE 10 2019 218 028 B4 describes a communication system for vehicles focused on Vehicle-to-Vehicle (V2V) and Vehicle-to-lnfrastructure (V2X) communication. This system primarily serves road safety by exchanging data such as speed, position, and direction between vehicles and infrastructure. This enables early detection of hazardous situations and the issuance of warnings to prevent collisions.

[0005] The objective of the invention is to create a secure and self-determined communication method between the vehicles in a fleet. 28 01 25

[0006] This objective is achieved by means of a communication system with the features of claim 1. Advantageous embodiments of the inventive communication system are regarded as advantageous embodiments of the inventive method, wherein the system's means are utilized to execute the method steps. Furthermore, advantageous developments of the invention are described by the dependent claims, the following description, and the figures. SUMMARY OF THE INVENTION

[0007] An aspect of the invention relates to a communication system for a vehicle fleet comprising a communication module integrated into each vehicle to enable wireless data transmission between the vehicles in the fleet, a contact database for storing a predefined list of vehicles that are part of the fleet, and a connection system for sending and receiving information. This communication system enables direct communication between vehicles within the fleet in a self-created and encrypted social network.

[0008] Technically, the communication module allows a stable, independent data transmission without requiring a mobile device or third-party app. The contact database enables targeted and controlled communication solely within the predefined group of vehicles, ensuring that only authorized vehicles are connected. The connection system allows real-time transmission of messages and other information, while encryption ensures secure communication. The advantage lies in a secure, autonomous connection option, customizable to individual needs.

[0009] In an advantageous embodiment of the invention, it is provided that communication between the vehicles in the fleet may take place in real-time or at specified intervals. This function allows users to adapt the frequency of data transmissions to the traffic situation, efficiently managing network resources.

[0010] Furthermore, in an advantageous embodiment of the invention, it is provided that communication takes place via an independent mobile network module, such as GSM. This mobile network module ensures connectivity independently of other external systems, enabling communication even in areas without mobile coverage.

[0011] Another advantageous embodiment includes a storage function in the vehicles of the fleet, allowing shared information and travel histories to be stored and replayed for 28 01 25 later review. This function provides users access to previous communications and location data, useful for efficient planning and documentation.

[0012] Additionally, an advantageous embodiment provides that the communication system may also be used via a mobile device. This feature adds flexibility, allowing users to optionally access the communications system’s functions via a mobile device, facilitating adaptation to various communication needs.

[0013] The invention addresses the problem of driver distraction due to the use of mobile phones, such as for making calls or sharing location while driving, which can be highly distracting whether done via voice command or manually. The solution presented here allows the driver to communicate with other drivers within their friend group without the need to connect to a phone. It reduces dependence on mobile phones and third-party apps for contacting or exchanging data while driving and enables a simple, direct connection to other vehicles. Especially on road trips with multiple vehicles, it can otherwise be difficult and cumbersome to communicate between vehicles, as this typically requires making phone calls. The invention's integrated "Road Trip" for example feature allows such information to be shared directly and effortlessly between the vehicles involved.

[0014] Current prior art does not offer a comparable function that allows vehicles to communicate directly with each other and manage their own contact circle based on a social network. The main difference is that existing solutions rely on compatibility with mobile apps. This invention, however, significantly reduces this reliance and enables vehicles to interact directly with each other. A location-sharing feature is similar to known applications but it is specifically tailored to the vehicle domain or to one domain.

[0015] Technically, the communication system provides an in-car app that creates and stores a “friend group” as a social network where the user can manage contacts with friends and family members. Through the built-in antenna and a GSM module as an example, the vehicle remains connected with other vehicles in the friend group. Internet access allows a user to call a friend's vehicle or share their own location directly through the vehicles, without the need for an external app. The communication system or the app also indicates which vehicle is currently in use and marked as "online," so that data is only shared with active vehicles if the user has enabled this. 28 01 25

[0016] New friends or vehicles can be added easily. The communication system or the app uses each vehicle’s user ID database, and the user can individually set the frequency of location sharing, for example, every 15 minutes or every hour for the next 24 hours. This ensures transparency in data transmission and optimizes network capacity usage.

[0017] Additionally, the communication system or the app includes a direct-call feature, allowing calls to be made to other vehicles in the friend group without needing to connect a mobile phone to the vehicle. An important use case for this invention is during group road trips, especially on longer journeys. It enables the easy exchange of information such as route or destination changes, parking locations, break and rest stops, preferred fuel stations, current locations, and / or playlists. Instead of using a separate phone app to share location or communicate with other vehicles, the invention offers a direct connection between the participating vehicles. This feature even allows trip updates to be sent to non-participating vehicles or previous road trips to be stored and later reviewed. In areas without cell service, vehicles can still communicate with each other if they are close enough.

[0018] The invention offers several advantages: By reducing driver distraction from using a mobile phone while driving, it improves safety for drivers, passengers, and other road users. In the event of theft or towing, if the owner's phone battery is dead, other contacts in the friend group can quickly locate the vehicle. Additionally, the solution provides a means of communication in areas without network coverage and introduces a social component by allowing a select circle of people to be directly accessible through the vehicle. Furthermore, sharing playlists or syncing songs enhances the driving experience on group trips.

[0019] To ensure the solution’s security, a cross-platform app that works with all car manufacturers is required. A possible workaround for security concerns would be to implement data transmission standards that only accept data in predefined formats to prevent unauthorized transmissions. Cybersecurity plays a critical role in this context.

[0020] In other words, the communication system provides a user-defined, secure, and independent communication solution for vehicles, enabling flexible and efficient communication within a defined vehicle fleet. The system allows easy management and storage of communication data, offering a comprehensive solution for coordination and information exchange among vehicles. 28 01 25

[0021] In yet other words, the communication system offers a high level of control and data protection for users. With the ability to store and analyze communication logs in the vehicles, the system is also valuable for fleet management and documentation, while the independence from mobile phones minimizes driver distraction and also enhances safety.

[0022] Another aspect of the invention relates to a computer program product containing program code for executing the method to run the communication system. This program product enables the implementation of functionalities such as direct communication between vehicles, data sharing, and friend network management within the communication system. Additionally, the invention includes a non-transitory computer-readable storage medium that securely stores this program, ensuring reliable execution and availability across the vehicle fleet network. Together, these components facilitate seamless operation of the communication system, enhancing user control and interaction in a connected vehicle environment.

[0034] In the following detailed description of the embodiment of the disclosure, reference is made to the accompanying drawing that forms part hereof, and in which is shown by way of illustration a specific embodiment in which the disclosure may be practiced. This embodiment is described in sufficient detail to enable those skilled in the art to practice the disclosure, and it is to be understood that other embodiments may be utilized and that changes may be made without departing from the scope of the present disclosure. The following description is, therefore, not to be taken in a limiting sense.

[0035] Fig. 1 shows a block Diagram of a Possible Implementation of a communication System 10 comprising a communication module integrated into each vehicle of the fleet for wireless data transmission between the vehicles of the fleet, a contact database for storing a predefined list of vehicles within the fleet and a connection system for sending and receiving information between the vehicles within the fleet. With this communication system 10, direct communication between the vehicles of the fleet may be possible, enabled within a self-created and encrypted social network.

[0036] The diagram illustrates a potential implementation process for establishing a friend circle within the vehicle's social network implemented by the communication system 10. This communication system 10 enables direct and selective sharing of data between trusted vehicles, independent of mobile devices. The setup process begins at step 12, labeled "Start," where the user initiates the connection process within the infotainment system.

[0037] In step 14, the user selects "Open the Circle App on the Infotainment System." This application serves as the interface for managing contacts within the vehicle's friend network, allowing drivers to define and control who can access shared information.

[0038] At step 16, the user inputs the "unique Car ID" of the friend’s vehicle. This unique identifier ensures that only designated vehicles can join the circle, maintaining the network’s exclusivity and security.

[0039] Following this, in step 18, the communication system 10 proceeds with "Authenticate Identity." Here, the unique Car ID is verified such as the own ID 19 to confirm the friend’s identity, reinforcing the security protocol and preventing unauthorized access. 28 01 25

[0040] Once the identity is authenticated, the user proceeds to step 20, "Select what to share with the new friend." This step allows the user to customize data-sharing preferences, such as location, trip information, or media playlists, ensuring that only intended information is shared within the circle.

[0041] Finally, in step 22, the setup concludes with "Done," signaling the successful addition of a new friend to the communication network.

[0042] This communication system 10 offers a seamless way for drivers to establish a trusted, encrypted social network within their vehicle, tailored for safe, distraction-free communication and data-sharing during travel.

[0043] Fig. 2 shows another block diagram of a communication process within the fleet network. The process begins at step 24 with "Open App," where the user accesses the communication application through the infotainment system. In step 26, the user selects a vehicle from the "Friends List" 27 to initiate contact with a chosen vehicle. Once selected, a wireless connection 28 is established with the target vehicle 30, which receives the call or message.

[0044] Alternatively, the communication system 10 supports voice command functionality 32, where the user can use voice recognition to call a friend by saying the saved contact name. This voice command triggers a wireless connection directly to the selected vehicle 30, allowing hands-free communication.

[0045] Fig. 3 shows a block diagram for creating a group trip or fleet network of multiple vehicles for a trip and a process of creating this trip with a coordinated communication and data sharing. The process begins at step 34 with "Start Trip," where the user initiates the setup for a group journey. In step 36, the user selects friends or vehicles to join the trip, inviting specific vehicles, such as Vehicle 38 and Vehicle 40, to participate in the shared journey.

[0046] Following the selection, step 44 enables data sharing, allowing the user to specify which types of information will be shared among the participating vehicles. Options include location sharing 46, playlist sharing 48, route selection 50, parking location 52, and / or call options 54, providing comprehensive sharing capabilities to enhance trip coordination and user experience.

[0047] Fig. 4 shows a block diagram to illustrate the exchange of information between the corresponding entities. The user’s own vehicle, represented by Vehicle 56, is shown as wirelessly receiving and transmitting trip information 58. This trip information 58 is accessible and modifiable for other invited vehicles, vehicle 38 and vehicle 40, based on the settings defined by the trip host. Each vehicle in the network can view or update shared data as permitted, creating a flexible and interactive environment for coordinated driving and group communication.

[0048] This communication system 10 enables both manual and voice-activated methods for seamless, secure, and distraction-free communication within the vehicle fleet’s network, enhancing convenience and safety. 28 01 25
