Seat-Based Driver Terminal Selection for Autonomous Driving Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver monitoring systems fail to accurately identify the driver when multiple portable terminals are present in a vehicle, leading to unnecessary alerts and potential safety risks during autonomous driving.
Innovation Solution
A vehicle information processing device that identifies a driver's terminal using authentication devices at each seat, sets the driver's terminal based on biometric authentication, and provides notifications only to that terminal, ensuring safe transitions between autonomous and manual driving modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alerts are made with respect to all portable terminals in the vehicle, then driver monitoring coverage is improved, but unnecessary notifications are generated and driver convenience deteriorates
Solution Approach 1:
The system segments portable terminals by assigning them to specific seats using authentication devices. Each seat has its own authentication device that identifies which portable terminal belongs to the occupant of that seat. This segmentation allows the system to distinguish the driver's terminal from other terminals in the vehicle, enabling targeted notifications only to the driver's terminal while maintaining comprehensive monitoring coverage.
2Device complexity
If the system cannot specify the driver's terminal among multiple terminals, then system complexity is reduced, but notification accuracy deteriorates
Solution Approach 1:
The system introduces authentication devices as intermediaries between portable terminals and the notification system. These authentication devices are provided at each seat and serve as mediators to identify which portable terminal belongs to which seat occupant. This intermediary mechanism enables accurate identification of the driver's terminal without significantly increasing overall system complexity, as the authentication devices are already integrated into the seat structure.
3Reliability
If notifications are provided to all terminals, then safety monitoring is improved, but driver attention is distracted
Solution Approach 1:
The system applies local quality by directing notifications selectively to the driver's terminal based on the driver's seat position and authenticated terminal association. Instead of uniformly notifying all terminals, the system locally targets only the driver's terminal with safety-critical notifications while allowing other terminals to remain undisturbed. This localized notification approach maintains safety monitoring effectiveness while eliminating unnecessary distractions to non-driver occupants.

AI summary
A vehicle information processing device, for application to a vehicle configured to perform all driving operations under a fixed condition, the device includes; a terminal identification section configured to identify a portable terminal corresponding to authentication information authenticated by an authentication device provided at the vehicle; a driver's terminal setting section configured to set a driver's terminal used by a driver, based on information received from the identified portable terminal; and a notification section configured to notify the driver's terminal in a case in which a predetermined condition is satisfied in an autonomous driving state in which all driving operations are performed by the vehicle.
