Adaptive Vehicle Driving Mode Using Occupant State And Road Type
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicles are limited to fixed driving modes based on user input, lacking the ability to adapt to occupant states and road conditions dynamically.
Innovation Solution
A method and apparatus that determine the occupant's state and the type of road to set a personalized driving mode, using a sensing unit, navigation information acquisition, and a controller to adjust driving parameters such as chassis control, acceleration/deceleration levels, and defensive driving based on occupant tasks and road type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vehicle provides fixed driving modes based on user input, then the system is simple and easy to operate, but it cannot adapt to different occupant states and road conditions
Solution Approach 1:
The driving mode is transformed from a static, fixed setting to a dynamic parameter that automatically adjusts based on real-time detection of occupant state (via sensing unit) and road conditions (via navigation information). The controller continuously modifies driving parameters including chassis control, acceleration/deceleration levels, and defensive driving settings to match current conditions, enabling the system to adapt without requiring complex manual reconfiguration.
Solution Approach 2:
The system performs self-adjustment by automatically detecting occupant state and road conditions, then autonomously selecting and applying appropriate driving modes without requiring explicit user input for each condition. The sensing unit and controller work together to self-regulate driving parameters based on pre-established criteria, reducing the burden on the user while maintaining system simplicity.
2Adaptability or versatility
If the vehicle uses multiple sensors and navigation systems to determine occupant state and road type, then adaptability improves, but device complexity increases
Solution Approach 1:
The sensing unit and navigation information acquisition unit serve multiple functions: the sensing unit detects both occupant presence and occupant state, while the navigation system provides both location data and road type information. The controller integrates these diverse inputs to perform multiple tasks including determining occupant state, identifying road type, and adjusting driving parameters. This multi-functionality reduces the need for separate dedicated components for each function.
Solution Approach 2:
The controller acts as an intermediary that processes information from the sensing unit and navigation system, then translates this data into appropriate driving mode selections. Rather than having direct complex interactions between multiple sensors and multiple control functions, the controller mediates by centralizing the decision-making process and coordinating all adjustments through a unified control mechanism.

AI summary
A method and an apparatus for setting a driving mode of a vehicle are disclosed. The method performed by an in-vehicle apparatus for setting a driving mode includes: determining a state of an occupant, determining a type of road on which the vehicle is traveling, and setting the driving mode of the vehicle based on the state of the occupant and the type of the road.
