Vehicle System Center Driving Mode Occupant Appropriateness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles capable of both manual and automated driving, switching from automated to manual driving can be challenging when the occupant is not appropriate to take control, leading to difficulties in maintaining the automated state or forcing the vehicle to stop.
Innovation Solution
A vehicle system with an occupant appropriateness detecting device, vehicle-side and center-side control devices, and communication systems that allow mode changes from automated to center driving when an occupant is deemed inappropriate, ensuring continuous vehicle operation through remote control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If switching from automated driving to manual driving is performed when the occupant is not appropriate as a driver, then the automated driving state can be maintained or the vehicle can be forcibly stopped, but the vehicle operation is interrupted and productivity is reduced
Solution Approach 1:
The patent introduces a center driving mode as an intermediary state between automated and manual driving. When automated driving cannot be maintained and manual driving is not appropriate, the vehicle transitions to center driving mode where a remote operator controls the vehicle. This intermediary mode resolves the contradiction by maintaining vehicle operation continuity (productivity) while ensuring safe control when the occupant is unsuitable for manual driving.
2Productivity
If a remote operator is introduced to handle cases where the occupant is not appropriate as a driver, then vehicle operation can continue, but the system complexity increases
Solution Approach 1:
The control device is designed with multi-functionality, capable of operating in three different modes: automated driving mode, manual driving mode, and center driving mode. This universal design allows a single control system to handle all driving scenarios, including cases where the occupant is not appropriate for manual driving. The center driving mode activates only when necessary, maintaining productivity without permanently increasing system complexity.

AI summary
A vehicle system includes: a plurality of vehicles (2) that include an occupant appropriateness detecting device (21) that detects appropriateness of an occupant (200) as a driver, a vehicle-side operation device (22) that is operated by the driver, a vehicle-side control device (28) that controls a traveling condition of the vehicle (2), and a DCM (24); and a control center (3) that includes a center-side communication device (31), and a center-side control device (33) that controls the traveling condition of the vehicle (2) via the vehicle-side control device (28). The vehicle-side control device (28) controls the traveling condition of the vehicle (2) in any driving mode of a manual driving mode through an operation of the vehicle-side operation device (22), an automated driving mode without depending on an operation of the vehicle-side operation device (22), and a center driving mode by the center-side control device (33). In a case where a mode change is performed from the automated driving mode to the manual driving mode, the mode change is performed to the center driving mode in the case of determining that the occupant (200) does not have appropriateness as a driver.
