Wireless Vehicle Interface Using Mobile Playback Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle user interfaces lack flexibility in operation, as they are typically fixed to specific locations and do not allow for seamless integration of external mobile devices to display and control vehicle functions from various positions within the vehicle.
Innovation Solution
A method and system that establishes a wireless data connection between the vehicle and a mobile display device, allowing for the transmission of vehicle operating parameters and enabling the mobile device to display and control vehicle functions, with the ability to switch between operating modes based on the device's attachment position, using techniques like WLAN or Bluetooth for data transfer.

Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed user interface is used in the vehicle, then the operation control is simple and reliable, but the flexibility and adaptability to different positions are poor
Solution Approach 1:
The mobile display device serves multiple functions: it acts as a display device, a control interface, and a docking station. The system allows the same device to be used by different occupants at different positions (driver, front passenger, rear passenger) with automatic adaptation to the respective seating position, eliminating the need for separate fixed interfaces at each location.
Solution Approach 2:
The system dynamically adapts the user interface based on the detected seating position of the mobile display device. When docked at different positions, the system automatically configures the appropriate controls and displays relevant information for that position, transforming a static system into a dynamic one that responds to changing conditions.
2Ease of operation
If multiple fixed control interfaces are provided at different positions, then the ease of operation from various positions is improved, but the device complexity and cost increase
Solution Approach 1:
Instead of providing separate fixed control interfaces at each position, the system uses a single universal mobile display device that can be moved and docked at different positions. The device universally provides control functionality for all vehicle systems regardless of where it is positioned.
Solution Approach 2:
The mobile display device creates a virtual copy of the fixed user interface through wireless communication. The display shows replicated control elements and vehicle information that mirror what would be available at fixed interfaces, allowing the same control experience to be accessed from any position.
3Adaptability or versatility
If a mobile display device is used for vehicle control, then the flexibility and position independence are improved, but the reliability and stability of control may be reduced
Solution Approach 1:
The docking station serves as an intermediary between the mobile display device and the vehicle's control systems. When the device is docked, the docking station establishes a stable wireless connection and acts as a reliable mediator for transmitting control commands and vehicle data, ensuring control stability despite the mobile nature of the display device.
Solution Approach 2:
The system replaces traditional mechanical wired connections with wireless communication technology. The mobile display device communicates with the vehicle systems wirelessly through the docking station, eliminating the need for physical cable connections while maintaining reliable data transmission and control stability.
4Ease of operation
If wireless data connection is established with mobile device, then the ease of connection and flexibility are improved, but the data transmission reliability and security may be affected
Solution Approach 1:
The docking station acts as an intermediary that manages the wireless connection between the mobile display device and the vehicle systems. It establishes and maintains the wireless data connection, handling authentication, data encryption, and transmission protocols to ensure reliable and secure communication while keeping the connection process simple for the user.

AI summary
The invention relates to a method and system for providing a user interface in a vehicle (1), wherein a wireless data link (8) is formed between the vehicle (1) and a mobile playback device (7) which is releasably connected in the vehicle (1) or is held freely by a user in the vehicle (1). In the method, operating parameters relevant for the operation of the vehicle are detected on the vehicle and information relating to detected operating parameters is displayed by a display and control unit (3, 4, 5, 6) which is installed in the vehicle and can be read from the driver's seat position. A wireless data link (8) is formed between the vehicle (1) and a mobile playback device (7) which is releasably connected in the vehicle (1) or is held freely by a user in the vehicle (1). Data for generating a display content (15a - 151) are transmitted via the wireless data link (8) from the vehicle (1) to the playback device (7), and on the basis of the transmitted data a display content (15a - 151) which comprises information about detected operating parameters displayed on the display and operating device (3, 4, 5, 6) is generated on the playback device (7).
