Obstacle Alert Control During Low-Speed Vehicle Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving technologies fail to appropriately cancel obstacle detection notifications when vehicles are parked or traveling at low speeds, leading to usability issues.
Innovation Solution
A control device and method that allows notification of obstacle detection to be stopped based on user input, and automatically resumes notification when the vehicle reaches a certain speed or when the obstacle is within a predetermined distance, ensuring appropriate notification during movement control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If notification of obstacle detection is muted during low-speed movement control, then usability is improved by reducing unnecessary notifications, but safety deteriorates because the mute state cannot be canceled when vehicle speed remains below the threshold
Solution Approach 1:
The notification cancellation condition is made dynamic by introducing multiple parameters (vehicle speed threshold and distance threshold) instead of a fixed speed threshold. The system automatically transitions between muted and notified states based on real-time evaluation of these dynamic parameters, allowing the mute state to be canceled when the obstacle distance satisfies the predetermined condition even during low-speed movement control.
2Device complexity
If notification is stopped based on fixed speed threshold, then system simplicity is maintained, but adaptability deteriorates because it cannot appropriately handle cases where vehicle speed does not reach the threshold during movement control
Solution Approach 1:
The system changes from using a single speed parameter to using multiple parameters (vehicle speed and obstacle distance) for determining notification cancellation. This parameter expansion allows the system to adapt to various scenarios including low-speed movement control, while maintaining relatively simple control logic by evaluating whether the distance between the vehicle and obstacle satisfies a predetermined condition.

AI summary
A control device including circuitry configured to: perform movement control for moving a moving body to a target movement position; detect an obstacle in surroundings of the moving body; and perform notification to a user of the moving body when the obstacle is detected. The movement control is control for moving the moving body at a first speed or less. The circuitry is configured to: stop the notification in response to a notification stop input from the user of the moving body; cancel the stop of the notification when a movement speed of the moving body is equal to or higher than a second speed; and during execution of the movement control, cancel the stop of the notification when a distance between the moving body and the obstacle satisfies a predetermined condition, and continue the stop of the notification when the distance does not satisfy the predetermined condition.
