Steering Wheel HOD Driver Ability Check for Real-Time Driving Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicles lack the ability to instantly determine a driver's physical or mental state, posing a risk of accidents due to poor driving conditions.
Innovation Solution
A driving ability determining system and method that utilizes a HOD device on the steering wheel to receive user inputs and a processing circuit to assess driving ability in real time, activating or deactivating driving functions based on the assessment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no driver monitoring system is implemented, then the vehicle operation remains simple and unrestricted, but driving safety deteriorates due to inability to detect poor driver condition
Solution Approach 1:
The system performs preliminary assessment of driver ability before allowing vehicle operation. A test instruction is generated and presented to the driver before driving begins, and the system evaluates the driver's responses in advance to determine if they are fit to drive, preventing unsafe operation from the outset
Solution Approach 2:
The system utilizes the driver's own inputs and responses during normal steering wheel interaction as the basis for ability determination. The HOD device embedded in the steering wheel captures the driver's natural operations, which are then analyzed by the processing circuit to assess driving ability without requiring separate monitoring equipment
2Reliability
If real-time driver ability determination is implemented, then driving safety improves through immediate detection of poor condition, but device complexity increases due to additional monitoring components
Solution Approach 1:
The system merges the driver monitoring function with the existing steering wheel structure. The HOD device is embedded directly into the steering wheel, combining the steering control function with the ability determination function into a single integrated component, thereby avoiding additional separate monitoring equipment
Solution Approach 2:
The steering wheel serves multiple functions: it acts as both the steering control device and the driver ability determination device. The HOD device embedded in the steering wheel captures both steering inputs and test responses, allowing the same physical component to fulfill multiple roles in the vehicle system
3Reliability
If driver ability assessment system is added, then ability to prevent accidents improves, but ease of operation deteriorates due to test instructions and user inputs required
Solution Approach 1:
The system maintains continuous monitoring of driver ability through ongoing analysis of steering wheel inputs. Rather than requiring discrete test interruptions, the HOD device continuously captures the driver's steering operations and responses, allowing seamless integration of assessment into the normal driving flow without breaking the continuity of useful driving action

AI summary
A driving ability determining system, provided in a vehicle and for determining a driving ability of a driver of the vehicle, comprising: a HOD (Hand Off Detection) device embedded on a steering wheel, configured to receive at least one user input, wherein the user input is generated by the driver responding to a test instruction; and a processing circuit, configured to determine the driving ability of the driver according to the user input. By using such system, the driving ability may be determined in real time. Also, the driving function of the vehicle may be stopped if the driving ability is determined to be poor. By this way, the safety of driving vehicles may be increased.
