Infrastructure Assistance Interface Module for Vehicle Update Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicles and RVO systems face challenges in efficiently communicating and updating interface specifications due to misinterpretations and limited computing capacity, leading to costly and complex updates, especially when developers are different entities.
Innovation Solution
An interface module processes infrastructure assistance data to generate a processing result, which is then transmitted to the motor vehicle, outsourcing complex calculations and conversions to the infrastructure, and allowing proprietary interfaces to be accommodated without direct updates to the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If interface specification updates are implemented in both RVO and motor vehicle, then communication compatibility is improved, but update complexity and cost increase
Solution Approach 1:
The patent introduces an interface module as an intermediary component that handles interface specification updates independently of the motor vehicle. This module acts as a mediator between the RVO system and the vehicle, allowing specification changes to be implemented without requiring direct updates to the vehicle's core systems, thereby reducing update complexity while maintaining communication compatibility.
Solution Approach 2:
The system is segmented into distinct functional components: the RVO system, the interface module, and the motor vehicle. This segmentation allows the interface specification updates to be isolated to the interface module only, rather than requiring updates across the entire system. The module can be updated independently, reducing the overall complexity of the update process.
2Reliability
If interface specification updates are implemented in both RVO and motor vehicle, then communication compatibility is improved, but update cost increases
Solution Approach 1:
The interface module serves as a cost-effective intermediary that can be updated independently of the expensive motor vehicle systems. By concentrating the update functionality in this single module rather than requiring vehicle-wide updates, the patent significantly reduces update costs while maintaining communication compatibility.
Solution Approach 2:
The interface module can be implemented as a more easily replaceable and updateable component compared to the motor vehicle's core systems. This allows for cheaper, more frequent updates of the interface specification without the high costs associated with vehicle software updates, effectively treating the interface module as a disposable or easily renewable component.
3Measurement precision
If complex calculations are performed in the motor vehicle, then processing accuracy is improved, but vehicle computing capacity requirements increase
Solution Approach 1:
The patent extracts complex calculation tasks from the motor vehicle and relocates them to the infrastructure side (RVO system and interface module). This extraction allows the vehicle to maintain high processing accuracy for critical functions while reducing its computing capacity requirements and energy consumption for non-critical calculations.
Solution Approach 2:
The interface module acts as an intermediary that performs complex data processing and calculations before transmitting results to the motor vehicle. This mediator handles the computationally intensive tasks, allowing the vehicle to receive pre-processed data that requires minimal additional computation, thereby reducing the vehicle's computing capacity requirements while maintaining processing accuracy.
