Vehicle Mode Management for Consistent Multi-System Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle control systems cannot detect inconsistencies between requests input to different functional systems and fail to adjust requests appropriately, especially for comprehensive or continuous requests involving multiple systems, leading to potential operational inconsistencies.
Innovation Solution
An information processing device with a processor that determines a mode for vehicle behavior in response to requests, transitions through various statuses and sub-modes, and controls the vehicle based on these transitions, ensuring centralized management of control conditions to prevent inconsistencies among functional systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each functional system determines cooperative control execution based only on direct input requests, then the system operates independently and simply, but inconsistency cannot be detected between requests from different functional systems
Solution Approach 1:
The patent introduces a central manager as an intermediary component that receives requests from multiple functional systems, adjusts them centrally, and distributes adjusted requests back to the respective systems. This mediator architecture enables consistent vehicle-wide control while maintaining relative simplicity at the individual functional system level.
Solution Approach 2:
The patent merges the request adjustment functionality into a centralized manager that consolidates control logic across multiple functional systems. By combining adjustment operations in one location, the system achieves consistent control decisions without requiring each functional system to independently handle complex coordination.
2Reliability
If requests are pre-adjusted in each functional system, then local control is achieved, but the request cannot be changed even if inconsistent with other functional systems
Solution Approach 1:
The patent performs preliminary adjustment of requests in a centralized manager before distribution to functional systems. This preliminary central adjustment ensures consistency is established upfront, while the centralized location maintains flexibility to modify requests based on overall vehicle state and multiple input sources.
Solution Approach 2:
The patent implements dynamic request adjustment where the centralized manager can modify requests based on real-time vehicle state, driver input, and coordination needs across functional systems. This dynamic adjustment capability allows the system to adapt requests flexibly while maintaining consistency.
3Adaptability or versatility
If the vehicle control system uses multiple functional systems with independent request processing, then system modularity is maintained, but comprehensive or continuous requests may not be appropriately adjusted
Solution Approach 1:
The patent creates a universal manager that handles multiple types of requests (comprehensive, continuous, discrete) from multiple functional systems through a unified adjustment process. This multi-functional approach enables appropriate handling of complex requests while maintaining a single coordination point that reduces overall system complexity.

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 that is related to usage and operation 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.
