Notification Control Apparatus for Distant Destination Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems fail to provide effective guidance when the estimated destination is far from the current vehicle position, as they can only notify information when the destination is relatively close.
Innovation Solution
A notification control apparatus that acquires passage probability information and current position information to determine a notification range, allowing the system to notify the driver of information relevant to the estimated destination, even when it is far away, by controlling a notification unit to display or audio-output content within a defined distance based on this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If notification is provided only when destination is close to current position, then notification frequency is reduced, but information delivery completeness deteriorates
Solution Approach 1:
The notification control apparatus performs preliminary actions by notifying the driver in advance when the vehicle is approaching the notification range, before the vehicle actually reaches the estimated destination. This allows the driver to be prepared for upcoming events or conditions at the destination, ensuring complete information delivery while maintaining appropriate notification frequency through advance warning rather than repeated notifications.
Solution Approach 2:
The notification range is dynamically adjusted based on the passage probability information and current position of the vehicle. When the vehicle is far from the estimated destination, the notification range is set further ahead, allowing notification to occur at appropriate distances. This dynamic adjustment ensures that notifications are provided at optimal times without excessive frequency, resolving the contradiction between complete information delivery and notification disturbance.
2Loss of information
If notification range is extended to cover far destinations, then information delivery completeness improves, but notification disturbance increases
Solution Approach 1:
The notification control apparatus applies local quality by providing notifications at specific locations along the route rather than continuously or at fixed intervals. The notification range is locally optimized based on the estimated destination and passage probability, ensuring that notifications are provided at the most appropriate locations where they will be most useful to the driver, thereby reducing overall notification disturbance while maintaining information completeness.
Solution Approach 2:
The system changes parameters by adjusting the notification range distance based on the estimated destination distance and passage probability information. When the estimated destination is far away, the notification range is set at a greater distance from the current position, and when the destination is closer, the notification range is adjusted accordingly. This parameter change allows the system to extend coverage to far destinations without causing excessive notification disturbance, as notifications are provided at optimally determined distances.

AI summary
An object is to provide a technique capable of appropriately notifying a driver of information on an estimated destination even when the estimated destination is relatively far from the current position. The notification control apparatus includes an acquisition unit and a control unit. The acquisition unit acquires passage probability information and current position information. The control unit makes the notification unit notify of a content within a range defined by a distance previously associated with a probability of the passage probability information and a current position of the current position information based on the passage probability information and the current position information acquired by the acquisition unit.
