Vehicle Infotainment System Priority-Based Function Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern vehicle infotainment systems require significant time to start, leading to delayed availability of functions, and large non-volatile memory is needed for quick system starts, which can increase boot time as the number of functions increases.
Innovation Solution
A method where user-set priorities determine the starting order of functions, utilizing a dual-processing system with a first processing device for quick startup and a second processing device for complex functions, allowing partial functionality to be available immediately while full functionality is achieved later.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a large non-volatile memory is used to store all function data for quick startup, then the system can provide fast access to functions, but the boot time increases as the number of functions increases
Solution Approach 1:
The patent segments the functions into multiple groups based on user-defined priorities (first group, second group, third group). Each group is stored separately in non-volatile memory and loaded in sequence. This segmentation allows the system to load only essential functions first (reducing initial boot time) while providing structured access to all functions, thereby resolving the contradiction between fast function availability and manageable memory complexity.
2Adaptability or versatility
If all functions are loaded simultaneously during system startup, then complete functionality is available, but the startup time becomes excessively long
Solution Approach 1:
The patent implements preliminary action by pre-defining priority groups of functions and pre-configuring their loading sequence. During startup, the system executes work programs in a predetermined sequence (first group, then second group, then third group), ensuring that essential functions are made available first. This preliminary organization allows the system to provide progressive functionality rather than waiting for complete system initialization, thus reducing perceived startup time while maintaining full adaptability.
3Area of stationary object
If discrete controls are integrated into the display system to save installation space, then the system becomes more compact, but the processing requirements and startup time increase
Solution Approach 1:
The patent segments the integrated control functions into priority-based groups that can be independently loaded and executed. By organizing integrated controls (climate control, seat adjustment, entertainment) into hierarchical priority groups, the system can activate essential controls faster while maintaining the space-saving integrated design. This segmentation reduces the processing bottleneck caused by integrating multiple functions into a single system.

AI summary
The invention relates to an information and entertainment system (11) of a vehicle (10). The information and entertainment system (11) provides a number of functions (A, B, C, X, Y, Z) that can be used by a user of the vehicle (10). In the method, an order of priority of the multiple functions is set by the user, wherein the order of priority states a time availability of the functions desired by the user after an activation of the information and entertainment system (11). In accordance with the set order of priority, the multiple functions are carried out after a starting of the information and entertainment system (11), and sub-functions of the multiple functions can be immediately made available.
