Pregnant Driver Vehicle Control With Biometric Support Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pregnant women face challenges while driving due to discomfort from seat belts, difficulty in operating pedals and steering, increased fatigue, and safety risks, as existing auxiliary devices are not integrated into vehicle control systems.
Innovation Solution
A vehicle system that determines and adjusts driving support functions based on biometric information such as pregnancy stage, using a controller to activate specific control functions and parameters, including seat and pedal adjustments, to enhance comfort and safety without requiring separate auxiliary devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a pregnant woman adjusts her seat position away from the steering wheel and pedals to relieve seat belt pressure, then comfort is improved, but the effort required to operate pedals and steering wheel increases
Solution Approach 1:
The patent replaces mechanical pedal operation with electronic control. The controller detects pedal contact through sensors and automatically generates control signals to operate vehicle functions, eliminating the need for mechanical force application at the pedals.
Solution Approach 2:
The patent introduces a controller as an intermediary between the driver and vehicle systems. The controller receives input from sensors detecting pedal contact and translates this into appropriate vehicle control actions, mediating the interaction between the driver's reduced-effort input and the vehicle's response.
2Ease of operation
If auxiliary devices such as pedal extenders and seat belt guides are added, then ease of operation and comfort are improved, but device complexity increases
Solution Approach 1:
The patent merges multiple auxiliary functions into a single integrated controller system. The controller combines pedal contact detection, signal generation, and vehicle function control into one unified device, replacing the need for separate mechanical auxiliary devices like pedal extenders and seat belt guides.
Solution Approach 2:
The controller performs multiple functions: detecting pedal contact, determining which vehicle function to activate, generating control signals, and adjusting control parameters. This multi-functional approach eliminates the need for multiple specialized auxiliary devices.
3Reliability
If the vehicle provides comprehensive control functions for pregnant women, then safety and comfort are improved, but the complexity of the control system increases
Solution Approach 1:
The patent implements dynamic control parameters that adjust based on detected conditions. The controller modifies acceleration limits, deceleration limits, and other parameters in real-time based on pregnancy detection and driving conditions, providing adaptive safety control rather than fixed complex rules.
Solution Approach 2:
The system uses sensor feedback to detect pedal contact and driver presence, then adjusts control functions accordingly. This feedback mechanism allows the system to provide comprehensive safety control based on actual driving conditions rather than requiring pre-programmed complex scenarios.

AI summary
A vehicle provides various functions for a pregnant woman and a method of controlling the same. The method of supporting vehicle driving for a pregnant woman may include determining whether to enter a driving support control for the pregnant woman based on at least one of an entry command or an input biometric information of a driver, determining a control function to be activated among predetermined control functions in the driving support control for the pregnant woman based on the at least one of the entry command or the biometric information when entering the driving support control for the pregnant woman, and performing the determined control function.
