Vehicle Motion Manager for Source-Agnostic Kinematic Plan Arbitration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle systems require significant design changes and time when a new application is added, leading to a slowdown in application updates and product deployment.
Innovation Solution
A motion manager that classifies kinematic plans into predetermined items such as motion amount, direction, and priority, allowing for the realization of vehicle motion without specifying the setting source of the plans, thereby reducing the need for design changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If identification information (ID) is assigned to each kinematic plan from applications, then the motion manager can specify and distinguish the setting source of each plan, but the number of design changes increases significantly when new applications are added
Solution Approach 1:
The patent extracts the identification information from the kinematic plan data structure itself and places it in a separate management layer. The motion manager maintains a mapping between application IDs and kinematic plans without embedding IDs in every plan transmission to actuators. This separation reduces the complexity burden on the actuator system while preserving traceability in the motion manager.
Solution Approach 2:
The motion manager implements a universal ID management mechanism that handles multiple applications through a common interface. Instead of requiring separate handling logic for each application ID in the actuator system, a single universal ID-to-plan mapping in the motion manager serves all applications, reducing overall system complexity.
2Reliability
If identification information is assigned to each kinematic plan, then the motion manager can track the setting source, but time is required for design changes and speed of application update slows down
Solution Approach 1:
The motion manager performs preliminary registration and mapping of application IDs to kinematic plans before actual motion execution. This pre-establishment of ID relationships allows for rapid deployment of new applications without requiring real-time design changes, as the ID management infrastructure is already in place to accommodate new applications.
Solution Approach 2:
The ID management system in the motion manager is designed to be dynamic and adaptable. New application IDs can be registered and mapped to kinematic plans without fixed structural constraints, allowing the system to evolve with new applications while maintaining traceability. This dynamic approach eliminates rigid design change requirements.
3Reliability
If identification information is assigned to each kinematic plan, then the setting source can be specified, but the system requires more design changes across motion manager and actuator system
Solution Approach 1:
The motion manager acts as an intermediary between applications and the actuator system. It maintains the application ID to kinematic plan mappings and handles the translation, so that actuators receive plans without embedded IDs. This intermediary role preserves identification capability where needed (motion manager) while simplifying the interface where it is not needed (actuator system).
Data Source
AI summary
A motion manager configured to request motion of a vehicle according to a kinematic plan on driver assistance of the vehicle to at least one of a plurality of actuators provided in the vehicle includes one or more processors. The one or more processors are configured to receive information indicating a plurality of kinematic plans and classify the information into predetermined items such that a realization method of achieving a purpose of each of the kinematic plans is selectable without specifying or distinguishing a setting source of each of the kinematic plans, arbitrate the kinematic plans, calculate a motion request to the vehicle based on a result of arbitrating the kinematic plans, and distribute the motion request to at least one of the actuators.
