Automated Driving Control Package for Driver Permission Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle control systems lack the ability for drivers to freely set permissions for individual driver assistance operations during automated driving, leading to unnecessary operations and increased driver unease due to unpredictable assistance and difficulty in adapting to changing conditions.
Innovation Solution
A control system that includes a package determining part to create driver assistance packages based on surrounding environment, vehicle, and driver information, allowing drivers to authorize specific operations and providing information on the package content to alleviate uncertainty.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the system performs all driver assistance operations during automated driving, then the automation level is improved, but the driver's unease increases due to unnecessary operations and lack of predictability
Solution Approach 1:
The patent segments driver assistance operations into different permission levels (first permission and second permission) and allows selective activation. The control unit permits only first driver assistance operations during automated driving, while second operations require additional driver permission. This segmentation reduces unnecessary operations and increases driver predictability, thereby reducing driver unease while maintaining appropriate automation levels.
2Adaptability or versatility
If the driver can set permission for individual driver assistance operations, then the adaptability to situation is improved, but the operation complexity increases making it difficult for the driver to set permissions
Solution Approach 1:
The patent merges multiple permission settings into a single switch operation. The switch unit provides a unified interface that simultaneously controls permission for multiple driver assistance operations. When the driver operates the switch, it collectively permits or restricts both first and second driver assistance operations, thereby maintaining adaptability while significantly simplifying the ease of operation.
Solution Approach 2:
The patent implements dynamic permission management where the system can transition between different permission states (first permission only, or first plus second permission) based on driver input. The control unit dynamically adjusts which operations are permitted without requiring the driver to configure each operation individually, balancing adaptability with operational simplicity.
3Loss of information
If the system provides detailed information about driver assistance operations to the driver, then the driver's awareness is improved, but the information processing load increases
Solution Approach 1:
The patent extracts and highlights only the most critical information for the driver - specifically, which driver assistance operations are currently permitted and which require additional permission. The information providing unit presents this essential information in a clear, concise manner without overwhelming the driver with excessive details, thereby improving driver awareness while managing information processing load effectively.

AI summary
An automated driving control part including a package determining part determining a driver assistance package packaging permissions for a plurality of driver assistance operations based on at least one of surrounding environment information, host vehicle information, and driver information, a package proposing part proposing to the driver to switch to a driver assistance package so as to obtain permissions for driver assistance operations permitted in the driver assistance package, a judging part judging if a driver has authorized switching to the driver assistance package proposed by the package proposing part, and a package content providing part providing information relating to the content of the driver assistance package authorized by the driver through the information providing device to the driver.
