Autonomous Route Switching for Sleeping Driver Delay Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving systems fail to address traffic congestion delays when the driver is asleep, leading to reduced convenience and comfort as the driver is not notified of the delay until waking up.
Innovation Solution
An autonomous driving device that detects delay factors on the approved route using traffic and weather information, determines if the driver is asleep, and automatically changes the travel plan to an alternative route without waking the driver, thereby reducing delay time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driver is allowed to sleep during autonomous driving, then the comfort and convenience of the driver is improved, but the system cannot respond to traffic congestion delays in time
Solution Approach 1:
The system monitors the driver's sleep state autonomously using sensors and automatically responds to traffic congestion by selecting alternative routes without requiring driver intervention. The system serves itself by detecting the driver's state and making independent decisions to maintain punctuality while preserving sleep comfort.
Solution Approach 2:
The system continuously receives feedback from traffic information systems about congestion on the current route and compares it with alternative routes. When delay is detected, the system provides feedback to the route planning module to trigger a route change, creating a closed-loop control system that responds dynamically to traffic conditions.
2Reliability
If the system notifies the driver of delay by waking them up, then the driver can respond to the situation, but the driver's comfort and sleep quality deteriorates
Solution Approach 1:
The system independently handles the notification task by automatically changing routes when congestion is detected, eliminating the need to wake the driver. The system serves the dual purpose of maintaining driver awareness of punctuality while preserving sleep comfort through autonomous route management.
Solution Approach 2:
The system performs preliminary route planning that considers multiple alternative routes in advance. When congestion is detected, the system can immediately switch to a pre-calculated alternative route without requiring driver wake-up or decision-making, thus maintaining both reliability and comfort.
3Productivity
If the system automatically changes route without driver approval, then the response speed to traffic congestion is improved, but the driver's control and decision-making authority is reduced
Solution Approach 1:
The system autonomously manages route changes by detecting congestion, evaluating alternative routes, and executing the switch without requiring driver approval. This self-service approach maximizes response speed while the system maintains adaptability by continuously monitoring traffic conditions and driver state to make intelligent routing decisions.
Solution Approach 2:
The system dynamically adjusts the level of driver involvement based on the situation. When the driver is asleep and congestion is detected, the system takes full control for rapid response. The system remains adaptable by being ready to transfer control back to the driver if needed, creating a flexible control structure that optimizes both speed and adaptability.

AI summary
An autonomous driving operation is performed at an automation level that allows a driver seat passenger to sleep. An approved route approved by the driver seat passenger is acquired. A predetermined delay factor existing on the approved route is detected based on traffic information or weather information. Based on an input signal from a passenger state sensor, it is determined whether the driver seat passenger is asleep. An alternative route that reduces a delay time using map data is searched when detecting the delay factor. A travel plan route is changed to the alternative route without acquiring approval from the driver seat passenger when the alternative route is acquired while the driver seat passenger is asleep.
