Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Small-sized terminals lack sufficient computation resources to execute multiple AI-based detection functions simultaneously, such as driver monitoring systems, limiting their capability to perform all necessary functions like face authentication, drowsiness detection, and inattentive driving detection.
Innovation Solution
A detection function control device that determines the vehicle situation based on ignition state, driver seating, vehicle acceleration, position, and sound, and activates appropriate detection functions accordingly, optimizing computation usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple AI-based detection functions are executed simultaneously in a small-sized terminal, then the detection capability is improved, but the computation resources are insufficient
Solution Approach 1:
The patent implements dynamic activation of detection functions based on vehicle situation. The control device determines whether to activate each detection function according to real-time vehicle conditions (ignition state, seating status, acceleration, position, speed, sound), making the system adaptable to different operating scenarios while managing computation resources efficiently
Solution Approach 2:
The system changes the activation state parameter of detection functions based on vehicle situation parameters. By monitoring changes in vehicle conditions (such as ignition on/off, acceleration thresholds, speed ranges), the system dynamically adjusts which detection functions are active, optimizing the balance between detection capability and computation resource consumption
2Adaptability or versatility
If all detection functions are activated in a small-sized terminal, then the detection coverage is improved, but the device complexity increases
Solution Approach 1:
The patent segments the detection function system into multiple independent detectable units (drowsiness detection, inattentive driving detection, face authentication, etc.). Each function can be independently activated or deactivated based on vehicle situation, reducing the overall system complexity while maintaining comprehensive detection coverage when needed
Solution Approach 2:
The system dynamically adjusts the number and type of active detection functions based on vehicle situation. Rather than having all functions permanently active, the system adapts the detection configuration to current operating conditions, simplifying the system state when full detection coverage is not required

AI summary
A detection function control device includes: a vehicle situation determining unit configured to determine a situation of a vehicle on the basis of detection results of one or more of an ignition state, whether a driver is seated in a seat, the acceleration of the vehicle, the position of the vehicle, the speed of the vehicle, and sound which is collected; and a detection function control unit configured to determine which of one or more detection functions for detecting dangerous driving is to be activated on the basis of the situation determined by the vehicle situation determining unit.
