Automated Driving Route Change Control Without Driver Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated driving systems face challenges in ensuring convenience during route setting changes, particularly when a driver does not have a periphery monitoring obligation, as changes in routes or destinations can disrupt the continuity of autonomous driving, leading to potential inconvenience and safety issues.
Innovation Solution
A presentation control device and program that monitor and notify the driver of the state of automated driving control, allowing for the determination of whether to continue autonomous travel control after route changes, and differentiate between system-initiated and driver-initiated changes to maintain safety and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If autonomous traveling control is implemented with no periphery monitoring obligation of driver, then driver convenience is improved, but safety and continuity of autonomous driving are worsened when route changes occur
Solution Approach 1:
The system provides feedback to the driver about the state of automated driving control through notifications. When a route change occurs, the notification control unit notifies the driver of the change in automated driving control state, ensuring the driver is informed while maintaining autonomous operation. This feedback mechanism balances convenience with safety by keeping the driver informed without requiring constant monitoring.
Solution Approach 2:
The system performs preliminary determination of whether to permit continuation of autonomous traveling control before actually continuing or interrupting it. The determination unit evaluates route changes and decides in advance whether autonomous control should continue, allowing the system to prepare appropriate actions (continuation or interruption) based on pre-assessment of safety conditions.
2Adaptability or versatility
If route changes are permitted during autonomous driving, then adaptability of the system is improved, but continuity of autonomous driving control is worsened
Solution Approach 1:
The system dynamically adjusts the state of automated driving control based on route changes. When a route change occurs, the determination unit evaluates whether to transition from autonomous control to manual control or maintain autonomous control. This dynamic adjustment allows the system to adapt to route changes while maintaining stability by making informed decisions about control continuity based on current conditions.
3Loss of information
If notification of automated driving control state is provided to driver, then information completeness is improved, but system complexity is worsened
Solution Approach 1:
The notification control unit extracts and provides only the essential information about automated driving control state changes to the driver. Instead of providing all possible system information, it selectively notifies the driver of specific state changes related to autonomous control, maintaining information completeness for safety-critical data while avoiding unnecessary complexity from comprehensive system monitoring.

AI summary
By a presentation control device or a non-transitory tangible computer-readable storage medium storing a presentation control program for controlling presentation of information related to an automated driving function that enables a subject vehicle to travel with autonomous traveling control with no periphery monitoring obligation of a driver, a state of automated driving control is grasped, and notification indicating the state of the automated driving control is provided. By an automated driving control device or a non-transitory tangible computer-readable storage medium storing a presentation control program, a change in a route to a destination set for the subject vehicle is grasped, and whether to permit continuation of the autonomous traveling control is determined.
