Vehicle Driving Control Mode Switching With Occupant-Gated Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving assistance technologies do not adequately adapt driving control to the surrounding situation and can become complicated when an occupant's operation differs, necessitating a more appropriate and intuitive control mechanism.
Innovation Solution
A vehicle control system that includes a recognizer to identify the surrounding situation, a driving controller to execute steering and speed control based on multiple control aspects, and an operator to receive occupant input, allowing switching between control modes based on the situation and preventing mode changes without explicit occupant instruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple control aspects are provided to adapt to different surrounding situations, then the adaptability of driving control is improved, but the device complexity increases
Solution Approach 1:
The system dynamically switches between different control aspects (first control and second control) based on the surrounding situation recognized by the recognizer. The driving controller adapts its control strategy in real-time by selecting appropriate control aspects, making the system flexible and adaptive without requiring multiple complete separate control systems.
Solution Approach 2:
A single driving controller is designed to execute multiple different control aspects (first control for automated lane changing, second control for other driving assistance operations). This multi-functional controller reduces overall device complexity by consolidating what could have been separate control systems into one universal controller that handles various driving scenarios.
2Adaptability or versatility
If switching between control aspects is allowed based on surrounding situation, then the appropriateness of driving control is improved, but the ease of operation deteriorates due to potential unexpected mode changes
Solution Approach 1:
The system incorporates feedback mechanisms where the driving controller monitors the surrounding situation through the recognizer and adjusts control aspects accordingly. Additionally, the system receives feedback from the operator about their preferences and operational patterns, using this information to predict when switching might be desired and to adjust switching behavior to match operator expectations.
Solution Approach 2:
The system performs preliminary actions by predicting the operator's intent based on recognized patterns of operation. When the system predicts that the operator would want to switch control aspects, it proactively prepares for or executes the switching before the operator explicitly requests it, thereby maintaining ease of operation while improving appropriateness.
3Productivity
If the system predicts operator intent to enable proactive switching, then the productivity of control operations is improved, but the reliability decreases due to potential incorrect predictions
Solution Approach 1:
The system applies partial prediction by analyzing only certain recognizable patterns of operator behavior rather than attempting to predict all possible actions. It focuses on predicting specific types of control aspect switches that are most beneficial and safest to predict, rather than over-predicting which would reduce reliability. This selective prediction approach maintains productivity while preserving reliability.
Solution Approach 2:
The system incorporates preliminary anti-action by having mechanisms to correct or prevent incorrect predictions before they can cause problems. When a prediction is made, the system prepares countermeasures such as allowing easy operator intervention to cancel the predicted action, or having fallback control strategies ready if the prediction proves incorrect, thereby maintaining reliability while enabling proactive switching.

AI summary
According to an embodiment, a vehicle control device includes a recognizer configured to recognize a surrounding situation of a vehicle, a driving controller configured to execute driving control for controlling at least one of steering and a speed of the vehicle on the basis of the surrounding situation, and an operator configured to receive an operation from an occupant of the vehicle. The driving controller executes the driving control on the basis of any one of a plurality of control aspects including first control and second control. The driving controller executes switching from the first control to the second control or switching from the second control to the first control when an instruction is received from the operator if the control aspect is switchable on the basis of the surrounding situation. The driving controller prevents the switching from being executed when the instruction is not received from the operator.
