Vehicle Occupant Assistance Control Based on Sensor Detection Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems do not adequately account for the detection accuracy of autonomous sensors, leading to false notifications and inefficient occupant assistance, particularly in conditions where communication devices are absent or unreliable.
Innovation Solution
A vehicle control apparatus equipped with an object detector, detection accuracy determiner, and occupant assister that assesses the detection accuracy of autonomous sensors and adjusts the mode of occupant assistance accordingly, ensuring accurate detection of mobile objects and providing appropriate assistance based on predefined conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If occupant assistance is performed based on detection information from autonomous sensors, then occupant assistance functionality is provided, but false notifications occur due to insufficient detection accuracy
Solution Approach 1:
The system changes the parameter of detection accuracy assessment by introducing a determination process that evaluates whether detection accuracy meets a predefined condition. Based on this assessment, the system adapts the occupant assistance mode: when accuracy is sufficient, standard assistance is provided; when accuracy is insufficient, alternative assistance modes are activated. This resolves the contradiction by dynamically adjusting system behavior based on detection reliability.
2Device complexity
If occupant assistance is performed without considering detection accuracy, then system complexity is reduced, but false detections lead to unnecessary notifications
Solution Approach 1:
The system performs a preliminary determination of detection accuracy before executing occupant assistance. This advance assessment prevents false notifications by evaluating whether the detection information is reliable enough to trigger assistance. The preliminary action of accuracy verification eliminates harmful false notifications without requiring complex real-time adjustments during assistance execution.
3Reliability
If detection accuracy condition is not met, then false detections are reduced, but occupant assistance may be delayed or insufficient
Solution Approach 1:
The system dynamically switches between different occupant assistance modes based on detection accuracy conditions. When accuracy conditions are met, standard assistance is provided; when not met, alternative assistance modes are activated. This dynamic adaptation ensures that assistance is always provided in an appropriate manner, balancing reliability requirements with timely response, without causing unnecessary delays.

AI summary
In an apparatus for controlling a vehicle equipped with an autonomous sensor and a communication unit, an object detector is configured to determine whether a predefined mobile-object condition is met, where the predefined mobile-object condition indicates that a mobile object detected from detection information received from an external device via the communication unit and a mobile object detected from detection information acquired from the autonomous sensor are the same object. An occupant assister is configured to perform occupant assistance for assisting an occupant of the vehicle, and configured to, in response to a detection accuracy condition being met, determine a mode of occupant assistance as a first mode, and in response to neither the detection accuracy condition nor the mobile-object condition being met, determine the mode of occupant assistance as a second mode is different from the first mode.
