Multi-User Vehicle OS Access Control Across Occupant Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle operating systems limit access to a single user profile, restricting user interaction and degrading the experience for non-operator occupants due to safety concerns, particularly with the integration of multiple displays in vehicles.
Innovation Solution
Implementing a single-instance, multi-user vehicle operating system that allows multiple user profiles to access and interact with the system concurrently, tailoring user experiences and restrictions based on occupant zones and display types to enhance safety and user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single user profile is limited to access the vehicle operating system instance, then operator safety is improved by preventing distraction, but user experience for non-operator occupants deteriorates
Solution Approach 1:
The patent segments the user experience into distinct user profiles (operator profile and non-operator profiles) that can concurrently access the same vehicle operating system instance. Each user profile has tailored restrictions and permissions, allowing the operator to have limited access during driving while non-operators can access full functionality on rear-seat displays, thus resolving the contradiction between safety and user experience.
2Ease of operation
If multiple user profiles are allowed to access the vehicle operating system concurrently, then user experience for non-operator occupants is improved, but operator safety may deteriorate due to potential distraction
Solution Approach 1:
The patent applies local quality by implementing location-aware restrictions where the operator's user interface is dynamically limited based on their position and driving state, while non-operator users in rear seats receive enhanced access. The system selectively applies different permission levels to different user profiles based on their location and role, allowing multiple concurrent users without compromising operator safety.
3Adaptability or versatility
If multiple displays are integrated in the vehicle cabin, then functionality and user experience are improved, but complexity of the system increases
Solution Approach 1:
The patent implements a single instance of the vehicle operating system that universally supports multiple user profiles across multiple displays simultaneously. This multi-functional approach allows one operating system instance to serve multiple users on multiple displays with different permissions and interfaces, avoiding the need for separate operating system instances for each display and thereby reducing overall system complexity while maintaining high functionality.

AI summary
A computing device comprising a memory configured to store an instance of a vehicle operating system (“VOS,” where the in stance of the vehicle operating system facilitates concurrent access by multiple user profiles) and processing circuitry configured to execute the instance of the VOS. The VOS may authorize the multiple user profiles to interface with the instance of the vehicle operating system via multiple displays communicatively coupled to the vehicle head unit, and, determine, based on which of the multiple displays with which each of the multiple user profiles interfaced to authorize each of the multiple user profiles, occupant zone identifiers. The VOS may also obtain, based on the occupant zone identifiers, and for each of the multiple user profiles, user experience restrictions, and restrict, via multiple user interfaces presented across the multiple displays by the single instance of the VOS and in accordance with the user experience restrictions, content.
