Vehicle Mode Management for Consistent Multi-System Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems cannot detect contradictions between requests input to different functional systems and cannot adjust requests even if they are inconsistent, leading to potential inconsistencies in the operations of multiple functional systems.
Innovation Solution
An information processing device with a processor that determines a mode for vehicle behavior in response to a request, transitions the vehicle's status among various states and sub-modes permitted in that mode, and controls the vehicle based on achieved status, ensuring centralized management of control conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If each functional system determines cooperative control execution based only on direct input requests, then the functional system operates independently and simply, but contradiction cannot be detected between requests input to different functional systems
Solution Approach 1:
The patent introduces a central manager as an intermediary that receives requests from multiple functional systems, adjusts them centrally, and distributes adjusted requests back to the functional systems. This mediator detects contradictions between requests from different functional systems and ensures consistent adjustment, resolving the reliability issue while maintaining operational independence of individual functional systems.
Solution Approach 2:
The patent merges the request adjustment function into a centralized manager that handles requests from multiple functional systems together. Instead of each functional system adjusting requests independently, the central manager combines all requests and performs unified adjustment, enabling detection and resolution of contradictions between requests while simplifying the overall system architecture.
2Ease of operation
If requests are pre-adjusted in each functional system, then local control is achieved, but the request cannot be changed even if the adjusted request is inconsistent with requests adjusted in other functional systems
Solution Approach 1:
The patent performs preliminary adjustment of requests in the central manager before distributing them to functional systems. This preliminary action ensures that requests are adjusted consistently across all functional systems while maintaining the ability to adapt to contradictions. The central manager prepares adjusted requests in advance, enabling both local control and overall flexibility.
Solution Approach 2:
The patent makes the request adjustment process dynamic by allowing the central manager to modify requests based on detected contradictions and system state. The adjustment is not fixed but adaptable, enabling the system to change requests when inconsistencies are found while maintaining ease of local operation through the standardized adjustment interface.
3Productivity
If a comprehensive request covering functions of multiple functional systems is processed, then overall vehicle control is achieved, but the request may not be appropriately adjusted or adjustment may not be established among functions of three or more functional systems
Solution Approach 1:
The patent segments the comprehensive request processing into manageable units by distributing adjusted requests to individual functional systems. The central manager divides the overall control task into separate adjusted requests for each functional system, making adjustment coordination feasible while maintaining overall cooperative control efficiency. This segmentation prevents overwhelming complexity in handling requests among three or more functional systems.

AI summary
An information processing device to be mounted on a vehicle includes a processor. The processor is configured to determine, in response to a request for the vehicle, one mode out of a plurality of modes defining behavior of the vehicle, make transition of a status of the vehicle among a plurality of statuses that is based on a state and a sub-mode, and control the vehicle based on the status of the vehicle that has been achieved by the transition. The state and the sub-mode are permitted in the determined mode.
