Passenger Support Device for Automated Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles operating in automatic driving mode, passengers often waste time in the cabin without productive activities, as existing systems do not effectively utilize this time due to lack of engaging and supportive measures.
Innovation Solution
A passenger support device that sets and informs behavior items to be performed during the journey, recognizes passenger actions, and provides support through a robot arm and interactive displays to ensure efficient use of time, allowing passengers to engage in activities within the limited vehicle space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic driving mode is used, then driving operation is automated and vehicle control is improved, but passenger time utilization deteriorates as passengers waste time in the cabin
Solution Approach 1:
The system enables passengers to serve themselves by providing an autonomous support system that automatically recognizes actions, informs appropriate behavior items, and provides support without requiring external assistance. The passenger support device operates autonomously to maximize passenger time utilization during automatic driving mode.
Solution Approach 2:
The system performs preliminary actions by pre-setting behavior items and preparing support mechanisms before the passenger needs them. The informing portion notifies passengers of upcoming behavior items in advance, and the action support portion prepares appropriate support actions based on predicted passenger needs, enabling efficient time utilization.
2Loss of time
If behavior support system is implemented, then passenger time utilization is improved through structured activities, but device complexity increases due to multiple recognition and support components
Solution Approach 1:
The passenger support device is designed as a universal system that performs multiple functions: action recognition, behavior item setting, informing, and action support. This multi-functional approach consolidates what would otherwise require separate systems into a single integrated device, managing complexity while providing comprehensive passenger support.
Solution Approach 2:
The system implements feedback loops where the action recognition portion continuously monitors passenger actions, the informing portion adjusts behavior item notifications based on recognition results, and the action support portion modifies support actions according to passenger responses. This feedback mechanism enables the system to adapt dynamically without requiring overly complex predetermined control logic.
3Productivity
If action recognition and support are provided, then passenger productivity is improved through guided activities, but information processing requirements increase
Solution Approach 1:
The system segments information processing into distinct functional modules: the action recognition portion handles sensory input and action identification, the behavior setting portion processes action patterns and determines appropriate behavior items, the informing portion manages notification delivery, and the action support portion handles support action generation. This segmentation distributes information processing load across specialized components, improving overall efficiency and reducing bottlenecks.

AI summary
There is provided a passenger support device including (i) an informing portion that sets behavior items to be performed by a passenger by a time a vehicle arrives at a destination and sets an order of performing the behavior items, the informing portion informing the passenger of the behavior items to be performed based on the order, (ii) an action recognition portion that recognizes an action of the passenger performing the behavior items, and (iii) an action support portion that supports the action of the passenger performing the behavior items, based on each of the behavior items and the action of the passenger recognized by the action recognition portion.
