Vehicle Cabin Odor Source Inference System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle cabin odor elimination systems do not effectively inform drivers about their own body odor, leading to potential discomfort for passengers.
Innovation Solution
An information processing system with odor sensors, a taximeter, and a terminal apparatus that infers whether the driver or a passenger is the source of the odor, providing notifications with recommended actions to reduce the odor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an odor sensor detects odor in the cabin and activates air purifier and scent generator, then the odor elimination function is provided, but the driver cannot recognize their own body odor and take appropriate actions
Solution Approach 1:
The system provides feedback to the driver about the odor source by analyzing odor characteristics and determining whether the driver or passenger is the source. When the driver is identified as the source, the system notifies the driver through the notification unit, enabling the driver to take appropriate actions such as opening windows or using deodorants.
Solution Approach 2:
The inference unit acts as an intermediary that analyzes odor data from the sensor and determines the odor source. It processes the raw odor information and translates it into actionable insights by identifying whether the driver or passenger is the source, then communicates this information to the notification unit for driver awareness.
2Ease of operation
If general odor elimination measures are taken without identifying the source, then the system responds to odor presence, but the driver cannot efficiently reduce odor caused by their own body odor
Solution Approach 1:
The system applies different responses based on the localized odor source. When the driver is identified as the source, specific notifications are provided to the driver. When the passenger is the source, different notifications are provided. This localized approach enables the driver to take appropriate actions only when necessary, improving both ease of operation and odor reduction efficiency.
Solution Approach 2:
The system changes the notification parameters based on the odor source identification. The notification content, timing, and method are adjusted according to whether the driver or passenger is the odor source, enabling more effective and context-appropriate driver actions for odor reduction.

Function Achieved in This Case
Enables drivers to efficiently reduce cabin odors by recognizing their own contribution and taking appropriate actions, thereby preventing passenger discomfort.
Implementation Method 1
an odor sensor detects an odor in the cabin of the vehicle
Data Source
AI summary
In an information processing system, a first acquisition unit acquires information on an odor in a cabin of a vehicle. An inference unit infers whether a source of the odor is a driver of the vehicle based on the information acquired by the first acquisition unit. A determination unit determines content of a notification provided to the driver according to an inference result of the inference unit.
