Personalized Vehicle Speed Limiting Through Software Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speed limiters in vehicles are typically hardware-based, limiting user customization and taking up space, while also only allowing on/off functionality.
Innovation Solution
A software-defined speed limiter system that allows user input for personalization settings through a user interface, enabling customization of speed limit activation and adjustment based on traffic signs, maps, user-defined preferences, and recommendation algorithms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hardware-based speed limiter is used, then the speed limiting function is provided, but user customization capability is limited and device space is occupied
Solution Approach 1:
The patent replaces the mechanical hardware-based speed limiter with a software-defined speed limiter system. The speed limiter settings are stored and processed electronically in the server and vehicle controller rather than through physical hardware switches or dials, enabling remote updates and personalized configurations without additional physical components in the vehicle.
Solution Approach 2:
The server-based system provides multiple functions through a single platform: it stores speed limiter settings, generates personalized recommendations based on driving behavior analysis, pushes settings to multiple vehicles, and allows users to modify preferences. This centralized system replaces multiple separate hardware components with one multi-functional software platform.
2Ease of operation
If a hardware speed limiter with on/off functionality is used, then the basic speed limiting function is achieved, but user personalization options are insufficient
Solution Approach 1:
The speed limiter system transitions from static on/off hardware control to dynamic software-based control where settings can be adjusted in real-time based on driving conditions, user preferences, and behavioral patterns. The system adapts to changing user needs through push notifications and remote updates without requiring physical reconfiguration.
Solution Approach 2:
The system automatically analyzes user driving behavior data and generates personalized speed limiter recommendations without requiring explicit user input for every setting. The server autonomously processes driving data, determines optimal speed limits based on patterns and preferences, and pushes configurations to the vehicle, reducing the operational burden on the user.
3Volume of moving object
If traditional speed limiters are used, then space is occupied in the vehicle, but a software-defined system saves space while providing more functionality
Solution Approach 1:
The speed limiter functionality is extracted from the vehicle's physical hardware and relocated to a remote server system. The server stores all speed limiter configurations and processing logic externally, with only minimal communication interfaces remaining in the vehicle. This extraction eliminates the need for dedicated hardware components within the vehicle interior, freeing up space while maintaining full functional capabilities through software.
