Dynamic Vehicle System Functionality Control via Communication Link
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems, such as infotainment systems, face challenges in dynamically controlling the availability and scope of functionalities based on the operating state of the vehicle, leading to static usability settings that do not adapt to changing legal requirements or driving conditions, causing distractions and inefficiencies.
Innovation Solution
A method that uses control parameters received via a communication link to dynamically control the availability and scope of vehicle system functionalities, allowing differentiation between various operating states, enabling adaptive functionality based on the vehicle's state without requiring software updates in the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Internet functionalities are permanently enabled or disabled in the vehicle software, then the functionality availability is fixed and simple to implement, but the system cannot adapt to changing legal requirements or driving conditions
Solution Approach 1:
The patent implements dynamic control of functionality availability by receiving control parameters via communication link that indicate whether the vehicle is in motion or stationary. The system dynamically enables or disables functionalities based on these parameters, transitioning from static software configuration to dynamic operational control based on real-time vehicle state
Solution Approach 2:
The patent introduces an intermediary control mechanism where control parameters are transmitted via communication link between an external source and the vehicle system. This intermediary layer enables flexible control of functionality availability without modifying the vehicle software itself, allowing external authorities to manage system behavior
2Ease of operation
If all Internet functionalities are available while driving, then the driver has full access to information, but the driver may be distracted from the driving task
Solution Approach 1:
The patent applies local quality by differentiating functionality availability based on specific operating conditions. When the vehicle is in motion, only certain functionalities are permitted while others are restricted. When stationary, full access is granted. This localized control of access rights based on vehicle state reduces distraction during driving while maintaining full functionality when parked
3Reliability
If the vehicle software is updated to comply with new legal requirements, then compliance is achieved, but the update process is time-consuming and requires software modification
Solution Approach 1:
The patent implements preliminary action by pre-configuring the vehicle system with the capability to receive and implement control parameters via communication link. Rather than requiring software updates when legal requirements change, the system is prepared in advance to accept external control instructions, enabling immediate compliance through parameter transmission without modification time
Solution Approach 2:
The communication link serving as an intermediary allows external authorities to transmit control parameters directly to the vehicle system. This intermediary mechanism enables rapid dissemination of legal requirement changes without the time-consuming process of software development, testing, and deployment cycles
