Automated Driving Mode Switching Notification System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated driving mode switching can occur unexpectedly, leading to unintended transitions between automated and manual driving, with vehicle occupants often unaware or unable to take preventive actions.
Innovation Solution
A vehicle control system that includes a recognition unit for situational awareness, an automated driving control unit for mode switching based on recognized conditions, a communication unit for sharing mode switching information with external devices, and an information providing unit for notifying occupants of frequent switching sites, allowing proactive actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If automated driving control switches modes based on peripheral situation recognition, then the automated driving control becomes more adaptive to different driving conditions, but unexpected mode switching occurs at timings not intended by vehicle occupants
Solution Approach 1:
The system performs preliminary action by notifying vehicle occupants in advance about upcoming mode switching sites before the actual switching occurs. The notification unit outputs information about specific locations where mode switching is expected, allowing occupants to prepare mentally and physically for the transition, thereby reducing the unexpected nature of the switching while maintaining adaptive mode changes based on peripheral conditions.
2Productivity
If automated driving mode switching occurs based on recognition unit data, then the driving control responds appropriately to environmental changes, but vehicle occupants cannot take preventive actions because they are unaware of the switching
Solution Approach 1:
The system implements feedback by providing continuous information to vehicle occupants about upcoming mode switching events. The notification unit delivers feedback about the system's internal decisions regarding mode switching, enabling occupants to understand when and why mode changes will occur. This feedback loop maintains the system's environmental responsiveness while simultaneously improving occupant awareness and ability to take appropriate actions.
3Loss of information
If mode switching information is shared with external devices, then collective data on switching sites can be accumulated, but the system complexity increases due to communication requirements
Solution Approach 1:
The system uses communication units as intermediaries to share mode switching information with external devices and other vehicles. These communication units act as mediators that handle the exchange of data about switching sites, allowing the accumulation of collective information without requiring complex direct interactions between all system components. The intermediary approach simplifies the overall system architecture while enabling information sharing and accumulation.

AI summary
A vehicle control system including: a recognition unit that is configured to recognize a peripheral situation of a subject vehicle; an automated driving control unit that is configured to execute a plurality of driving modes including an automated driving mode of automatically performing at least one of speed control and steering control of the subject vehicle, and switch a driving mode that is executed on the basis of the peripheral situation recognized by the recognition unit; a communication unit that is configured to transmit information related to switching sites switched to a driving mode in which the degree of automated driving is low by the automated driving control unit on the basis of the peripheral situation recognized by the recognition unit to an external device, and receive information related to a specific site derived on the basis of the information related to the switching sites, which is collected from vehicles, from the external device; and an information providing unit that is configured to output predetermined information in a case where the subject vehicle approaches the specific site indicated by the information related to the specific site which is received by the communication unit.
