Unified Vehicle Control Routing via Protocol-Agnostic Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems require multiple applications to support different communication protocols, making them inefficient and user-unfriendly, as users need to select the appropriate protocol for each operation, which can be opaque and cumbersome.
Innovation Solution
A vehicle control intermediary programming system that accepts communication-protocol-agnostic requests, assesses candidate communication links based on criteria like reliability, latency, and signal strength, and selects the optimal protocol-specific link to send directives to the vehicle, allowing unified applications to operate across multiple protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate applications are used to support different communication protocols, then protocol compatibility is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent merges multiple protocol-specific applications into a single unified application that can communicate with vehicles using different protocols (CAN, LIN, Ethernet, etc.). The application includes a protocol selection interface that allows users to choose the appropriate protocol, consolidating what would otherwise require separate applications for each protocol type.
Solution Approach 2:
The application is designed with multi-functionality to support multiple communication protocols through a single unified interface. It can detect vehicle communication protocols automatically and adapt to different protocol types (CAN, LIN, Ethernet, FlexRay) within the same application, making it universally compatible rather than protocol-specific.
2Measurement precision
If users manually select communication protocols, then protocol selection precision is improved, but ease of operation deteriorates
Solution Approach 1:
The application performs preliminary protocol detection automatically when connecting to a vehicle, analyzing the communication bus to identify which protocol (CAN, LIN, Ethernet, etc.) is being used before the user needs to make a selection. This preliminary detection reduces the complexity of manual protocol selection while maintaining accuracy.
Solution Approach 2:
The application introduces an intermediary protocol detection and selection mechanism that sits between the user and the vehicle communication interface. This intermediary layer automatically detects protocols and presents simplified options to users, mediating between the need for precise protocol selection and ease of user operation.
3Reliability
If protocol-specific applications are used, then communication reliability is improved, but productivity deteriorates
Solution Approach 1:
The application dynamically adapts to different communication protocols based on vehicle detection, automatically adjusting its communication methods for CAN, LIN, Ethernet, or FlexRay networks. This dynamic adaptation maintains communication reliability for each specific protocol while eliminating the need for users to switch between multiple static protocol-specific applications, thereby improving productivity.

AI summary
A system comprises a computer having a processor and a memory, the memory storing instructions executable by the processor to receive a communication-protocol-agnostic vehicle control request for a vehicle, determine, based on the communication-protocol-agnostic vehicle control request, a vehicle control operation to be executed at the vehicle, identify, from among a plurality of candidate communication-protocol-specific communication links, a communication-protocol-specific communication link via which to send a vehicle control directive to the vehicle, and send the vehicle control directive to the vehicle via the identified communication-protocol-specific communication link to cause the vehicle to execute the vehicle control operation.
