Solution Overview

Problem

Current steering input apparatuses lack the ability to dynamically adjust manipulation sensitivity based on detected object information, leading to potential lane invasions or collisions due to excessive steering wheel manipulation.

Innovation Solution

A steering input apparatus that includes a power provision unit, an interface unit for receiving object information, and a processor that adjusts the manipulation sensitivity of the steering wheel's rotation input by controlling the power provision unit based on detected objects, such as vehicles, barriers, or trees, to provide appropriate feedback and prevent accidents.

1Speed

If the steering wheel manipulation sensitivity is kept high for responsive steering control, then the steering responsiveness is improved, but the risk of excessive steering input leading to lane invasion or collision increases

Engineering Contradiction:

Improvesteering responsivenessVSAvoidrisk of lane invasion or collision

Core Design Contradiction:

SpeedVSObject-affected harmful factors

Solution Approach 1:

The patent implements dynamic adjustment of steering manipulation sensitivity based on real-time detection of surrounding objects. The processing unit receives object information from detection devices and dynamically modifies the manipulation sensitivity of the steering wheel through the power provision unit, allowing the system to adapt steering responsiveness to current driving conditions rather than maintaining a fixed sensitivity level

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system establishes a feedback loop where detection devices continuously monitor the driving environment for objects such as vehicles, barriers, and streetlights. This object information is fed back to the processing unit, which then adjusts the steering manipulation sensitivity accordingly, creating a closed-loop control system that responds to environmental conditions

Inventive Principle:

Principle #23Feedback

2Reliability

If the steering manipulation sensitivity is reduced to prevent excessive steering input, then the safety is improved, but the steering responsiveness deteriorates

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSSpeed

Solution Approach 1:

The patent applies different manipulation sensitivity levels in different spatial contexts. When objects are detected in specific zones around the vehicle, the system locally adjusts the steering sensitivity for those directional inputs, allowing high responsiveness in safe directions while applying reduced sensitivity in directions that could lead to collision with detected objects

AI summary

A steering input apparatus includes a steering input apparatus including a power provision unit for providing power to rotation input through a steering wheel, an interface unit for receiving object information indicating an object located in front of or around a vehicle, and a processor for adjusting manipulation sensitivity to the rotation input of the steering wheel by controlling the power provision unit based on the object information.
