Drive Mode Switch Control Device for Autonomous Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In autonomous drive vehicles, emergency avoidance situations often require driver intervention, but the initial driver operations may not accurately reflect their intention due to reflexive or continuous actions without proper operation adjustment, leading to inappropriate drive mode switching.
Innovation Solution
A drive mode switch control device and method that acquires operation information to detect first and second operations, switching from autonomous to coordination and then to manual drive modes based on operation thresholds, ensuring the driver's intention is reflected in the drive operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drive mode switch is executed when the driver performs a drive operation in autonomous drive mode, then the driver can take control in emergency situations, but reflexive or continuous operations may trigger inappropriate mode switching
Solution Approach 1:
The system performs preliminary detection of drive operations and evaluates whether they represent genuine driver intention before executing mode switching. By detecting operations in advance and analyzing their characteristics (reflexive vs. intentional), the system prepares for appropriate mode transitions while avoiding premature or incorrect switching.
Solution Approach 2:
The system implements feedback mechanisms to analyze the characteristics of detected drive operations. By evaluating operation patterns, continuity, and contextual information, the system determines whether an operation reflects genuine driver intention, providing feedback that prevents inappropriate mode switching while enabling reliable transitions.
2Ease of operation
If the system detects drive operations to switch from autonomous to manual mode, then driver intervention is enabled for emergency avoidance, but continuous or adjusted operations without clear intention may cause false switching
Solution Approach 1:
The system performs preliminary detection and evaluation of drive operations before executing mode switching. By analyzing operation characteristics in advance and comparing them against criteria for genuine driver intention, the system ensures that mode transitions occur only when the driver clearly intends to take control, preventing false switching from continuous or adjusted operations.
Solution Approach 2:
The system implements feedback mechanisms to continuously evaluate whether detected operations represent genuine driver intention. By analyzing operation patterns, continuity, and contextual information, the system provides feedback that distinguishes intentional interventions from reflexive or continuous adjustments, ensuring accurate intention detection while maintaining ease of legitimate driver intervention.

AI summary
A drive mode switch control device acquires operation information. The drive mode switch control device switches a drive state among at least an autonomous drive state, a manual drive state, and a coordination drive state. The operation detection unit detects a first operation and a second operation based on the operation information when the drive state is not in the manual drive state. The second operation is the drive operation different from the first operation and input after the input of the first operation. The drive mode switch control device switches the drive state from the autonomous drive state to the coordination drive state based on a detection determination of the first operation. The drive mode switch control device switches the drive state from the coordination drive state to the manual drive state based on a detection determination of the first operation.
