Vehicle Control Device Package-Based Permission Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle control devices do not allow drivers to freely set permissions for individual driving assistance operations in automated driving mode, leading to unnecessary operations being performed and difficulties in adverse weather conditions.
Innovation Solution
A control device that acquires surrounding environment, vehicle, and driver information to generate driving plans and extract driving assistance packages, which are then proposed to the driver with priority orders for approval, enabling selective execution of assistance operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the driver switches to automated driving mode, then automated driving operations are performed including vehicle distance control and lane tracking control, but the driver cannot freely set permissions for individual driving assistance operations
Solution Approach 1:
The patent segments the permission setting mechanism by introducing a package management system where driving assistance operations are grouped into selectable packages. Each package contains specific combinations of driving assistance operations, allowing the driver to enable or disable entire groups of functions rather than configuring each operation individually. This segmentation resolves the contradiction by maintaining comprehensive automation while simplifying the permission setting process through package-based selection.
Solution Approach 2:
The patent applies preliminary action by pre-configuring driving assistance operations into packages that are prepared in advance. The system automatically generates and presents appropriate packages to the driver before automated driving begins, based on the planned driving route and environmental conditions. This allows the driver to make informed permission decisions ahead of time, resolving the contradiction between comprehensive automation and ease of operation by eliminating the need for complex real-time configuration.
2Reliability
If the driver can freely set permissions for individual driving assistance operations, then unnecessary operations can be prevented from being performed, but the operation for setting these permissions becomes troublesome
Solution Approach 1:
The patent merges multiple individual driving assistance operations into unified packages that can be enabled or disabled as a group. Related operations are combined based on their functional relationships and typical usage patterns. This merging resolves the contradiction by reducing the number of individual permission settings the driver must make, while still allowing precise control over which operations are executed. The driver sets permissions at the package level rather than for each individual operation, simplifying the process while maintaining reliability.
Solution Approach 2:
The system applies self-service by automatically generating and presenting appropriate driving assistance packages to the driver based on the planned driving route, surrounding environment, and vehicle conditions. The system performs preliminary analysis and recommends suitable packages without requiring the driver to manually configure each operation. This self-service approach resolves the contradiction by automating the package selection process while maintaining driver control through approval or modification of the suggested packages.
3Adaptability or versatility
If driving assistance packages are proposed based on driving plan and surrounding conditions, then suitable operations are selected for the current situation, but the system complexity increases
Solution Approach 1:
The patent implements dynamics by making the driving assistance packages adaptive to changing driving conditions, surrounding environment, and planned route. The system dynamically generates and updates packages based on real-time information, allowing the set of available operations to change according to the current situation. This dynamic approach resolves the contradiction by providing high adaptability through context-aware package selection, while the package structure itself remains relatively simple and manageable.
Solution Approach 2:
The system applies preliminary action by pre-processing driving route information and surrounding environment data to generate appropriate driving assistance packages before automated driving begins. The package extraction part analyzes the driving plan and identifies suitable packages in advance, presenting them to the driver before execution. This preliminary processing resolves the contradiction by performing complex analysis upfront, allowing the actual driving execution to use pre-determined packages, thereby reducing real-time system complexity while maintaining high adaptability.
