Vehicle Startup Suggestion Device for Driving Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional driving support device guide systems fail to effectively suggest the startup of driving support devices during stressful conditions, leading to underutilization and reduced driver stress relief.
Innovation Solution
A startup suggestion device and method that acquire state values and preference values to suggest the startup of driving support devices, such as adaptive cruise control and lane keeping assist, based on comparisons between the two, using a human machine interface control unit to actively offer support during stressful driving conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the guide of driving support device is not performed when driver rejects it, then driver convenience is improved, but driving support device cannot be activated when driver is in stressful state
Solution Approach 1:
The system continuously monitors driver state through feedback mechanisms (eye tracking, steering operation detection, inter-ocular distance measurement) and dynamically adjusts guide provision based on detected stress levels, allowing the system to respond to changing driver conditions while respecting previous rejections
Solution Approach 2:
The system changes the parameter of guide provision from a static binary decision (guide or no guide) to a dynamic parameter that varies based on driver stress state, enabling selective re-provision of guides when stress thresholds are exceeded
2Reliability
If driving support device is actively suggested to startup, then driver stress is reduced, but system complexity increases
Solution Approach 1:
The human machine interface control unit performs multiple functions: it manages startup suggestions, monitors driver state through multiple sensors, determines stress levels, and controls guide provision. This multi-functionality reduces the need for separate dedicated systems for each function
Solution Approach 2:
The system automatically monitors driver state and autonomously determines when stress relief is needed, then actively suggests startup without requiring driver initiation, making the system self-activating based on detected conditions

AI summary
A startup suggestion device that is mounted on a vehicle together with a driving support device for assisting a driving operation of a driver or taking a wheel, and suggests a startup of the driving support device to the driver, includes: a state value acquisition unit that acquires a state value indicative of a traveling state of the vehicle; a preference value acquisition unit that acquires a preference value reflecting the traveling state preferred by the driver; and a startup suggestion unit that suggests the startup of the driving support device according to a comparison between the state value and the preference value.
