Vehicle Assistance System Context-Specific Information Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle information systems fail to provide context-specific information to drivers when transitioning between different spatial zones or mobility contexts, such as crossing borders or changing transportation modes, leading to a lack of relevant data availability during these critical moments.
Innovation Solution
A vehicle assistance device equipped with a control unit, display device, position determination system, sensor devices, and memory for storing vehicle states and positions, which compares current conditions to stored data to display context-specific information, including welcome and farewell menus, through various input/output modalities.

1Loss of information
If the vehicle information system displays general information continuously, then the driver receives constant data updates, but the driver does not receive context-specific information when transitioning between spatial zones or mobility contexts
Solution Approach 1:
The system stores multiple pieces of information in advance, each associated with different vehicle states or spatial zones. Before the vehicle actually transitions to a new context, the system has already prepared the relevant information in memory, ready for immediate display when the transition occurs. This eliminates the delay of retrieving information after the transition has happened.
Solution Approach 2:
The control unit continuously monitors the vehicle's current state and position, comparing it against stored state information. When a change in state or spatial zone is detected, the system provides feedback by displaying the appropriate context-specific information. This closed-loop feedback mechanism ensures information is provided exactly when needed based on actual vehicle conditions.
2Reliability
If the system monitors and compares vehicle states and positions continuously, then context-specific information is provided accurately, but the system complexity increases
Solution Approach 1:
The system divides information into discrete segments, each associated with a specific vehicle state or spatial zone. Instead of processing continuous streams of data, the control unit compares the current state against a finite set of predefined states. This segmentation simplifies the comparison logic while maintaining accurate context detection.
Solution Approach 2:
The control unit performs multiple functions using a single processing mechanism: it monitors vehicle state, determines spatial zone, compares current state with stored states, and triggers appropriate information display. This multi-functionality reduces the need for separate dedicated systems for each task, thereby reducing overall system complexity.

AI summary
The invention relates to a vehicle assistance apparatus (100) comprising a control device (1100) for controlling the display of information and a display device (1200) for displaying the information. When the control device (1100) has determined a condition of the vehicle (1) and/or a position of the vehicle, the control device (1100) provides information for the driver on the display device (1200) depending on the determined condition of the vehicle (1) and/or the determined position of the vehicle (1). The vehicle assistance apparatus (100) can provide a driver with the necessary information for each of the mobility sections when changing between mobility sections in which different information can be of interest for the driver.
