Adaptive Driver Assistance Control for Physical Disabilities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional driver assistance systems in vehicles are not effectively tailored to accommodate the unique physical characteristics of elderly or disabled drivers, leading to increased accident rates due to their fixed settings and complex adjustment processes.
Innovation Solution
A method and system that dynamically control driver assistance functions based on the driver's physical characteristics, such as age, visual acuity, auditory acuity, and physical disabilities, by selecting from multiple assistance levels including pedal sensitivity control, path recommendation, haptic or auditory outputs, enlarged alert ranges, and emergency reporting, using input devices and controllers to tailor the assistance according to individual needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional driver assistance systems use fixed settings designed for normal drivers, then the system structure remains simple and easy to manufacture, but the system becomes less effective and unsafe for elderly or disabled drivers
Solution Approach 1:
The driver assistance system dynamically adjusts its configuration based on the driver's physical characteristics. The controller automatically modifies assistance levels, alert ranges, and system sensitivities according to detected driver attributes (age, visual acuity, auditory acuity, physical disabilities), transforming a static system into an adaptive one that optimizes safety for each driver without requiring manual configuration
Solution Approach 2:
The system changes operational parameters such as alert range, assistance level, and sensitivity thresholds based on driver characteristics. For example, elderly drivers receive enlarged alert ranges and heightened sensitivity settings, while drivers with physical disabilities receive adjusted manipulation assistance levels, allowing the same hardware to serve diverse driver populations effectively
2Reliability
If the system provides customizable assistance settings for different driver needs, then safety and effectiveness improve, but the adjustment process becomes complicated and inconvenient
Solution Approach 1:
The driver assistance system performs self-configuration by automatically detecting driver characteristics and adjusting its parameters without user intervention. The controller receives input about driver attributes and autonomously selects appropriate assistance levels, eliminating the need for drivers to navigate complex manual adjustment interfaces while still providing personalized settings
Solution Approach 2:
The system pre-configures appropriate assistance settings based on detected driver characteristics before the driver begins operating the vehicle. By automatically determining and applying suitable assistance levels in advance, the system eliminates the need for drivers to perform complicated adjustments during the driving process
3Manufacturing precision
If the system uses detailed individual adjustments for each function, then customization precision improves, but the number of required manipulations increases
Solution Approach 1:
The system merges multiple individual adjustment functions into a single automated process. Instead of requiring separate manual adjustments for alert range, sensitivity, assistance levels, and other parameters, the controller integrates these functions and simultaneously configures all parameters based on driver characteristics, achieving detailed customization without requiring multiple separate manipulations

AI summary
The present disclosure relates to a vehicle where a driver assistance function can be controlled differently according to the physical characteristic of the driver, and a method for controlling the same function. One embodied method for controlling a driver assistance function may comprise steps of obtaining at least one of body-reaction state information and manipulation disability state information, the body-reaction state information related to a driver's situation cognition and reaction and the manipulation disability state information being for physical disability in relation to manipulation of a vehicle; selecting at least one assistance level corresponding to the obtained information among a plurality of assistance levels, each level corresponding to a different driver assistance function; and conducting control of the vehicle based on the selected at least one assistance level.
