Autonomous Drop-Off Control With Visual Feedback for Driverless Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in specifying a detailed drop-off location when using an automatic drive vehicle without a driver, as they cannot communicate or adjust the location effectively due to the lack of real-time visual feedback and interaction.
Innovation Solution
The automatic drive vehicle is equipped with an autonomous travel control, recognition, visualization processing, and user interface components that allow users to visualize the surroundings, specify a detailed drop-off location, and adjust the vehicle's route accordingly, including deceleration and pause tasks, with historical data used to identify high-frequency stop locations for optimal navigation.

Engineering Contradiction Analysis
1Extent of automation
If the automatic drive vehicle travels autonomously without a driver, then automation level is improved, but the user's ability to adjust detailed drop-off location deteriorates
Solution Approach 1:
The system provides real-time visual feedback by displaying surrounding images captured by the recognition portion to the user. This allows the user to see the actual environment around the vehicle and make informed decisions about the detailed drop-off location, effectively compensating for the absence of a driver through information feedback.
Solution Approach 2:
The user interface portion acts as an intermediary between the autonomous vehicle system and the user. It receives the user's operational input (desired drop-off location) and transmits control signals to the autonomous travel control portion, enabling communication and control adjustment without a physical driver present.
2Productivity
If the vehicle travels at normal speed to the drop-off location, then productivity is improved, but the user's ability to specify detailed location deteriorates
Solution Approach 1:
The autonomous travel control portion periodically adjusts the vehicle's speed based on the user interface state. When the user interface portion is providing operational input, the system reduces speed to allow the user sufficient time to specify the detailed drop-off location, then resumes normal speed afterward, creating a periodic speed adjustment pattern.
3Ease of operation
If the vehicle stops frequently to allow user input, then ease of operation is improved, but productivity deteriorates
Solution Approach 1:
The system implements periodic speed reduction rather than complete stops, maintaining movement while allowing user input. This approach provides user interaction opportunities without completely halting the vehicle, thereby reducing the impact on overall travel time compared to frequent stopping.
Data Source
AI summary
The transportation vehicle determines whether the calculated distance is equal to or less than the predetermined distance (step S14). If the determination result of step S14 is positive, the transportation vehicle searches for the closest stoppable location to the current location (step S15). The transportation vehicle also performs the pause task at the closest stoppable location. The transportation vehicle performs visualization processing of the surrounding circumstances of the drop-off location, and displays the processed image on touch-screen. The user specifies the detailed drop-off location while looking at the touch-screen (step S16).
