Driving Assistance Warning Suppression for Unavoidable Passing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving assistance systems issue unnecessary warnings when a vehicle passes a leading vehicle in a no-passing zone, especially in objectively unavoidable situations, causing driver irritation.
Innovation Solution
A driving assistance apparatus with a no-passing determining unit, vehicle detecting unit, operation state recognizing unit, and warning control unit that determines whether a warning is necessary based on the operation state of the leading vehicle, only issuing a warning if the passing maneuver occurs in a no-passing zone and the leading vehicle is not in a passing-allowed condition.

Engineering Contradiction Analysis
1Reliability
If the driver is issued a warning when passing a leading vehicle in a no-passing zone, then the safety of passing maneuvers is improved, but unnecessary warnings are generated when passing is objectively unavoidable, causing driver irritation
Solution Approach 1:
The system changes the parameters used for warning determination by incorporating the operation state of the leading vehicle (speed, acceleration, braking) into the decision-making process. When the leading vehicle exhibits abnormal operation states such as deceleration or braking, the system adjusts its warning behavior to suppress unnecessary alerts, thereby maintaining safety monitoring while reducing driver irritation from false warnings
Solution Approach 2:
The system implements feedback by continuously monitoring the operation state of the leading vehicle and using this information to adjust warning issuance. The warning control unit receives feedback about the leading vehicle's acceleration, deceleration, and braking states, and dynamically determines whether to issue warnings based on this feedback, ensuring that warnings are only given when truly necessary

AI summary
A driving assistance apparatus determines whether or not a road section corresponding to a current location of an own vehicle corresponds to a no-passing zone. A leading vehicle present ahead of the own vehicle is detected. An operation state of the detected leading vehicle is recognized. A passing maneuver performed by the own vehicle to pass the detected leading vehicle is detected. A warning operation to output a warning to a driver of the own vehicle is performed, when the passing maneuver is detected under a condition that the road section corresponding to the current location is determined to correspond to the no-passing zone. The warning operation is prohibited when the recognized operation state of the leading vehicle meets a predetermined passing-allowed condition that is a condition under which passing is allowed.
