In-Vehicle Web Presentation Safety Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-vehicle infotainment systems restrict web browsing due to safety concerns, such as small buttons, distracting content, and lack of hands-free voice control, preventing users from accessing certain web features like search engines or hyperlinks, and there is a need for standardized web content that adheres to vehicle-specific safety regulations.
Innovation Solution
A system that utilizes a defined standard for allowable web content within vehicles, including user interface layout requirements, voice control integration, and specific formatting, which redirects web requests to a vehicle-specific subdomain for safe and compliant content presentation, using a server to identify and redirect requests, and a web browser client that formats and validates content according to vehicle-specific criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If web browsing is enabled in-vehicle, then information accessibility is improved, but driver safety deteriorates due to distracting content and unsafe interface elements
Solution Approach 1:
The patent introduces an intermediary validation system that acts as a mediator between web content and the vehicle's display system. This validation mechanism checks web content against safety criteria before allowing display, blocking harmful elements while permitting safe information access. The intermediary layer filters content based on predefined safety rules, enabling information accessibility without compromising driver safety.
Solution Approach 2:
The system changes the parameters of web content presentation by imposing specific constraints on interface elements (such as minimum button sizes, prohibited distracting animations, and restricted content types). These parameter changes transform standard web content into vehicle-safe content, maintaining information accessibility while eliminating safety hazards through modified display parameters.
2Adaptability or versatility
If standard web interfaces are used in vehicles, then web content compatibility is improved, but ease of operation deteriorates due to small buttons and lack of hands-free control
Solution Approach 1:
The patent implements a universal validation framework that works across multiple web content types and sources while simultaneously supporting various interaction modes (voice commands, touch interfaces). This multi-functional approach allows the system to maintain compatibility with diverse web content while providing standardized hands-free operation capabilities through voice control integration, resolving the contradiction between versatility and ease of operation.
Solution Approach 2:
The system replaces mechanical interaction (manual button pressing, clicking) with voice-based control mechanisms. By substituting the mechanical interaction model with acoustic input recognition, the system enables hands-free operation while maintaining compatibility with standard web interfaces. The voice control system interprets speech commands to navigate and interact with web content, eliminating the need for physical manipulation of small interface elements.
3Object-affected harmful factors
If web browsing restrictions are imposed for safety, then driver safety is improved, but adaptability deteriorates as users cannot access certain web features
Solution Approach 1:
The patent segments web content evaluation into distinct validation categories (safe elements, restricted elements, prohibited elements). This segmentation allows the system to selectively block only harmful features while permitting access to safe and useful web functionalities. By dividing the content assessment into discrete segments, the system achieves fine-grained control over web feature accessibility, maintaining driver safety without unnecessarily restricting legitimate web usage.

AI summary
One or more controller may extract voice commands from retrieved web content, format the web content according to vehicle computing system (VCS) specific formatting information, provide the formatted web content for display by the VCS, and update the recognized voice commands of the VCS according to the extracted voice commands. A server may identify whether a received web request for web content is directed to a vehicle sub-domain for providing an in-vehicle-specific version of the content, identify whether the received web request is for presentation of web content via a VCS, and redirect the web request to the vehicle sub-domain when the request is not directed to the vehicle sub-domain and is for presentation via the VCS.
