Vehicle Controller Mode Transition Manipulation Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face challenges adapting to transitions between autonomous and manual driving modes, requiring time to adjust to steering and pedal manipulation, and there is a need to ensure driver convenience by considering driving situations when switching between modes.
Innovation Solution
A controller system that determines the range of operator manipulation based on driving situations, allowing smooth transitions between autonomous and manual driving modes by limiting or enabling driver input according to road conditions, vehicle states, and surrounding environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle transitions from autonomous driving mode to manual driving mode, then the driver can take control of the vehicle, but the driver requires time to adapt to manipulating steering and pedals
Solution Approach 1:
The system performs preliminary actions by gradually introducing manual control elements before full manual mode activation. The controller progressively enables steering and pedal manipulation within safe ranges, allowing the driver to adapt incrementally rather than suddenly, thus reducing adaptation time while maintaining safety
Solution Approach 2:
The system dynamically adjusts the degree of manual control allowed based on driving conditions and driver readiness. The controller modifies manipulation ranges in real-time, transitioning from restricted to full manual control as the driver demonstrates competence, creating a flexible adaptation process that balances safety with driver autonomy
2Ease of operation
If the vehicle transitions from manual driving mode to autonomous driving mode, then driver convenience is increased, but the vehicle must accurately determine driving situations to operate safely
Solution Approach 1:
The controller performs multiple functions within a single integrated system: it monitors driving situations, determines autonomous driving feasibility, manages mode transitions, and controls vehicle operations. This multi-functional approach consolidates complexity into a centralized unit rather than requiring separate specialized systems for each function
Solution Approach 2:
The system continuously monitors driving situations and uses this feedback to determine whether autonomous driving conditions are met. The controller adjusts its decisions based on real-time feedback from sensors and system states, enabling safe autonomous operation while maintaining the flexibility to transition back to manual mode if conditions change

AI summary
Methods and apparatuses are provided for controlling a vehicle. The vehicle is controlled to operate in an autonomous driving mode in which the vehicle is driven without a manipulation by an operator of the vehicle. A request to switch to a manual driving mode, in which the vehicle is driven with the manipulation by the operator, is received. A range of the manipulation regarding a function of the vehicle is determined according to a driving situation of the vehicle in response to the request. The vehicle is controlled to operate in the manual driving mode in which the manipulation by the operator is limited according to the range of the manipulation.
