Driving Assistance Device Shift Range Interference Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving assistance technologies do not effectively address the need for improved preventive safety in vehicle-to-vehicle communication systems, particularly in situations where the vehicle is not intended to move.
Innovation Solution
A driving assistance device equipped with a calculation unit to determine potential interference with other vehicles based on communication results, an arithmetic processing unit to generate notification signals when interference is predicted, and an identification unit to deactivate these processes when the vehicle's shift range suppresses movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the arithmetic processing unit continuously monitors and generates notifications for potential interference with other vehicles, then preventive safety is improved, but unnecessary notifications are generated when the vehicle is stationary, reducing driving comfort
Solution Approach 1:
The system dynamically adjusts its monitoring behavior based on the vehicle's operational state. The identification unit detects whether the vehicle is stationary or moving, and the arithmetic processing unit accordingly activates or deactivates interference monitoring. This dynamic adaptation prevents unnecessary notifications during stationary periods while maintaining safety monitoring during movement, resolving the contradiction between continuous safety monitoring and driving comfort.
2Reliability
If the driving assistance device continuously performs arithmetic processing to detect potential interference, then safety monitoring is maintained, but energy consumption increases
Solution Approach 1:
Instead of continuous arithmetic processing, the system implements periodic monitoring that is triggered only when the vehicle is in motion. The identification unit periodically checks the vehicle state, and the arithmetic processing unit activates interference detection only during movement phases. This periodic action pattern maintains safety monitoring capability while significantly reducing energy consumption during stationary periods.
3Reliability
If the system provides comprehensive driving assistance notifications, then preventive safety is enhanced, but notification frequency increases causing driver annoyance
Solution Approach 1:
The system applies different notification qualities based on local conditions - specifically, whether the vehicle is stationary or moving. During stationary periods, the notification function is suppressed regardless of detected interference potential. During movement, full notification functionality is restored. This local quality differentiation ensures safety notifications are provided only when contextually appropriate, reducing overall notification frequency and driver annoyance while maintaining preventive safety during critical driving phases.

AI summary
A driving assistance device, which is to be mounted on a vehicle capable of communicating with another vehicle, comprises a calculation unit configured to calculate a travel route of the another vehicle based on a communication result with the another vehicle, an arithmetic processing unit configured to determine whether the self-vehicle will interfere with the another vehicle traveling on the travel route calculated, and to generate a notification signal for giving a notification that the self-vehicle will interfere with the another vehicle, upon determination that the self-vehicle will interfere with the another vehicle, and an identification unit configured to identify a state of a shift range of the self-vehicle, wherein in a case where the shift range identified by the identification unit suppresses a movement of the self-vehicle, the arithmetic processing unit is deactivated.
