Driving Control Apparatus for Automated to Manual Mode Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation systems fail to allow drivers to transition from automated driving to manual driving securely, as they maintain automated driving characteristics, making it difficult for drivers to feel secure when taking over manual control, especially in complex situations.
Innovation Solution
A driving control method and apparatus that adjusts driving characteristics from automated driving to switch driving characteristics suitable for manual driving, including reducing vehicle speed and increasing inter-vehicular distance, to facilitate a safe and secure transition from automated to manual driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the navigation apparatus maintains automated driving characteristics during the switch to manual driving, then the automated driving performance is preserved, but the driver cannot start manual driving feeling secure
Solution Approach 1:
The patent applies dynamics by making the driving characteristics adjustable and transitionable. The system dynamically switches from automated driving characteristics to manual driving characteristics based on the driving mode. This allows the driving behavior to adapt to the current operational context, enabling a smooth transition that maintains reliability during automated driving while improving ease of operation during manual driving by providing familiar, predictable characteristics.
Solution Approach 2:
The patent implements parameter changes by modifying driving characteristics parameters when switching from automated to manual driving mode. The system changes parameters such as acceleration profiles, deceleration rates, and steering responses to match manual driving expectations. This parameter transformation resolves the contradiction by maintaining automated driving performance through controlled parameter adjustments while enabling drivers to feel secure during manual operation.
2Device complexity
If the switch to manual driving is made while maintaining automated driving characteristics, then the transition process is simplified, but the driver experiences anxiety and insecurity
Solution Approach 1:
The patent applies preliminary action by preparing the driving characteristics for manual driving mode in advance before the actual mode switch occurs. The system pre-adjusts parameters and characteristics to match manual driving expectations, so when the transition happens, the driver immediately experiences familiar and secure driving behavior. This eliminates driver anxiety without requiring complex real-time adjustments during the transition moment.
3Stability of the object's composition
If automated driving characteristics are maintained during mode switch, then system consistency is preserved, but driver takeover is unsafe
Solution Approach 1:
The patent resolves this contradiction through dynamic adaptation of driving characteristics based on operational mode. The system maintains stability and consistency within each mode while dynamically transitioning between modes by adjusting characteristics appropriately. During automated driving, the system maintains consistent automated characteristics; during manual driving, it switches to characteristics suited for manual operation, ensuring both system consistency within modes and safety during transitions.
