Solution Overview

Problem

Existing driving assistance devices face issues with driver authentication failures leading to incorrect recognition of set driving assistance functions, potentially causing these functions to malfunction or not activate as intended.

Innovation Solution

A driving assistance device that stores setting information for each driver, authenticates the driver upon ignition, and displays setting information via icons on a display unit, allowing correct recognition of active functions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If setting information is displayed on the display unit, then the driver can correctly recognize active driving assistance functions, but the display may interfere with the driver's operation

Engineering Contradiction:

Improvedriver recognition of set functionsVSAvoiddisturbance to driving operation

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The display shows setting information only during specific periods: when the driver first starts the vehicle and when settings are changed. This periodic display approach provides necessary information for recognition while minimizing continuous visual distraction during driving operations.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

Setting information is displayed in advance before the driver begins driving operations. This preliminary display ensures the driver recognizes active functions before potential distractions occur, then the display can be minimized or hidden during actual driving.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If authentication is performed when ignition is turned on, then the driver can start driving with correct function recognition, but the authentication process may delay vehicle startup

Engineering Contradiction:

Improvecorrect function activation at startupVSAvoidvehicle startup time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Authentication and setting information retrieval are performed as preliminary actions during the ignition-on sequence. By integrating these operations into the existing startup routine rather than adding separate steps, the system ensures correct function activation without significantly extending overall startup time.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The authentication process is merged with the ignition-on sequence and setting display operations. These multiple functions (authentication, setting retrieval, information display) are combined into a single integrated startup routine, reducing the cumulative time impact while ensuring all necessary actions are completed before driving begins.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

There is provided a driving assistance device configured to assist driving of a vehicle, the driving assistance device being configured to store, in a storage unit, pieces of setting information regarding settings of a plurality of driving assistance functions mounted on the vehicle for each of a plurality of drivers, and acquire, when a driver of the vehicle is authenticated, the setting information corresponding to the authenticated driver from the storage unit, and display, on a display unit recognizable by the driver of the vehicle, an indication regarding the acquired setting information.
