External Driving Terminal for Expandable Vehicle Autonomy Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current autonomous driving systems in vehicles are limited by proprietary software and lack updates, restricting users from experiencing full autonomous driving capabilities due to manufacturers' closed systems and limited functionalities, even though vehicles are equipped with the physical capabilities for advanced control signals.
Innovation Solution
A driving support system that includes a terminal with processors to connect with a vehicle's communications port, obtaining image and driving information to execute driving programs for assistive and autonomous operations, determining the highest level of ADAS functionality between the terminal and vehicle programs, and selectively implementing functionalities to enhance vehicle control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manufacturers use closed proprietary systems for autonomous driving programs, then system reliability and control are improved, but adaptability and functionality are reduced
Solution Approach 1:
The patent introduces an external terminal device as an intermediary between the user and the vehicle's autonomous driving system. This terminal can download and execute driving programs from external servers, acting as a mediator that bridges the closed vehicle system with the open external software ecosystem, thereby enabling functionality updates without compromising system control
2Device complexity
If manufacturers provide limited autonomous driving functionalities, then device complexity is reduced, but adaptability and user experience are worsened
Solution Approach 1:
The system transitions from a static, manufacturer-fixed driving program configuration to a dynamic, user-selectable program architecture. Users can download, install, and switch between different driving programs based on their needs, making the system adaptable and flexible while maintaining relatively simple hardware complexity
3Manufacturing precision
If manufacturers restrict driving program updates after vehicle manufacture, then manufacturing precision and quality control are improved, but adaptability and productivity are reduced
Solution Approach 1:
The patent separates the driving program from the vehicle hardware, allowing the program to be independently updated, downloaded, and installed on the terminal device. This segmentation enables continuous program updates and improvements without requiring hardware modifications or compromising manufacturing quality control
