In-Vehicle Update Determination Using Dynamic Position and Map Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for updating in-vehicle devices lack flexibility in determining whether an update process can be executed, as they rely solely on pre-registered position information, limiting the ability to assess appropriateness.
Innovation Solution
An information processing apparatus that uses a combination of vehicle position information, map information, and prohibition conditions to dynamically determine if an update process can be executed, considering factors like location, vehicle type, congestion, and communication state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pre-registered position information is used to determine update process executability, then the determination process is simple, but the flexibility and appropriateness of the determination are insufficient
Solution Approach 1:
The patent transforms the static pre-registered position information into a dynamic determination system that evaluates multiple changing factors including current position, vehicle type, congestion level, and communication state. This allows the update process executability to be dynamically assessed based on real-time conditions rather than fixed pre-registration, resolving the contradiction between flexibility and complexity by making the system adaptive to varying circumstances.
Solution Approach 2:
The patent introduces multiple variable parameters (position, vehicle type, congestion, communication state) that can change independently to determine update executability. By changing these parameters dynamically rather than relying on a single pre-registered position parameter, the system achieves greater flexibility and appropriateness in determination while managing complexity through modular parameter evaluation.
2Reliability
If multiple factors are considered for update determination, then the appropriateness of determination improves, but the processing complexity increases
Solution Approach 1:
The patent segments the update determination process into distinct evaluation components: position evaluation, vehicle type evaluation, congestion evaluation, and communication state evaluation. Each factor is assessed independently and then integrated to form the final determination, which improves reliability by thoroughly considering multiple factors while managing processing complexity through structured segmentation of the evaluation logic.
Solution Approach 2:
The patent performs preliminary evaluations of each factor (position, vehicle type, congestion, communication state) before making the final update determination. By pre-assessing each individual factor and its executability, the system builds a comprehensive understanding of the current state, which improves the appropriateness of the final determination while organizing the processing complexity into manageable preliminary steps.

AI summary
An information processing apparatus according to the present disclosure includes a memory, and a hardware processor coupled to the memory. The hardware processor is configured to: determine whether an update process of updating a program or data for providing a function of an in-vehicle device mounted on the vehicle is executable, based on position information of a vehicle, map information, and a prohibition condition indicating a condition for prohibiting execution of the update process; and cause the in-vehicle device to execute the update process when the determining that the update process is executable.
