Vehicle Control Interface Box for Autonomous Fault Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving systems fail to create appropriate driving plans in response to vehicle failures during operation, necessitating a system that can output requests for maintenance, return to a garage, or stop the vehicle based on failure information.
Innovation Solution
A vehicle control interface box that interfaces between the autonomous driving system and the vehicle platform, outputting requests for maintenance, return to a garage, or stop based on failure information, ensuring appropriate vehicle operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the autonomous driving system is mounted on an existing vehicle platform, then the system can be added without great modification to the vehicle, but the system lacks the capability to create appropriate driving plans in response to vehicle failures
Solution Approach 1:
The system is divided into independent modules: the autonomous driving system (compute assembly) and the vehicle control interface box. This segmentation allows the autonomous driving system to be mounted on existing vehicles without great modification, while the vehicle control interface box independently provides failure response capabilities by receiving failure information from vehicle systems and generating appropriate driving plans.
Solution Approach 2:
The vehicle control interface box acts as an intermediary between the vehicle's failure information systems and the autonomous driving system. It receives failure information from various vehicle systems, processes this information, and generates appropriate driving plans (such as safe stop, return to garage, or continue operation) which are then transmitted to the autonomous driving system for execution.
2Reliability
If the vehicle control interface box outputs multiple types of requests based on failure information, then the autonomous driving system can respond appropriately to failures, but the complexity of the control system increases
Solution Approach 1:
The vehicle control interface box uses parameter changes to manage complexity. It receives failure information with different parameters (failure type, severity, vehicle state) and based on these parameters, selects from a predefined set of driving plans. This approach allows comprehensive failure response without requiring complex decision-making logic, as the system transitions between discrete operational states based on failure parameters.

AI summary
A VCIB performs processing including issuing a request for maintenance after a vehicle returns when the vehicle is carrying out autonomous driving, a failure occurs, and the vehicle is able to continue a service operation, stopping the service operation and outputting a back request when the vehicle is unable to continue the service operation and the vehicle is able to travel, and stopping the service operation and outputting a stop request when the vehicle is unable to continue traveling.
