Vehicle Handover Control Using Autonomous Transition Buffer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving handover control systems face challenges in smoothly transitioning vehicle control from one driver to another, often resulting in uncomfortable interference between the driving operations of the first and second drivers, especially when switching from remote or occupant driving to automatic driving.
Innovation Solution
A driving handover control device that transitions from remote or occupant driving by a first driver to automatic driving and then to remote or occupant driving by a second driver, using a processor to manage the switching process and minimize interference by ensuring safe and quick transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If driving is handed over directly from the first driver to the second driver, then the handover process is simple and quick, but interference occurs between the driving operations of the first and second drivers causing discomfort
Solution Approach 1:
The patent introduces automatic driving as an intermediary state between remote/occupant driving by the first driver and remote/occupant driving by the second driver. This mediator absorbs the interference between the two drivers' operations, allowing smooth transition without direct conflict. The automatic driving mode acts as a buffer that receives control from the first driver and transfers control to the second driver without their operations overlapping.
Solution Approach 2:
The patent segments the direct handover process into two distinct phases: first from the first driver to automatic driving, then from automatic driving to the second driver. This segmentation separates the overlapping control operations in time, eliminating interference while maintaining relatively quick handover through the use of automated transition protocols.
2Object-affected harmful factors
If transition through automatic driving mode is implemented, then interference between drivers is suppressed, but the handover process becomes more complex
Solution Approach 1:
The automatic driving mode serves multiple functions: it acts as a buffer between drivers, ensures safe transition, manages control transfer protocols, and maintains vehicle operation during handover. This multi-functionality consolidates the complexity into a single automated system rather than requiring separate control mechanisms for each aspect of the handover process.
Solution Approach 2:
The system performs self-service by automatically managing the transition protocols between driving modes. The control device autonomously coordinates the handover process, monitors driver status, and executes mode transitions without requiring manual intervention or complex coordination between multiple control systems, thereby reducing operational complexity.
3Device complexity
If direct handover between drivers is performed, then the system remains simple, but driver comfort and safety are reduced due to operation interference
Solution Approach 1:
Automatic driving serves as a mediator that eliminates the uncomfortable interference experienced by drivers during direct handover. By introducing this intermediate automated control layer, the system prioritizes driver comfort and safety, allowing each driver to operate without feeling the other's inputs during the transition period.
Solution Approach 2:
The system dynamically adjusts the control mode based on the handover phase. During transition periods, automatic driving is activated to absorb interference, while during stable driving phases, the system operates in remote or occupant driving mode. This dynamic adaptation optimizes both comfort and efficiency without requiring a permanently complex system architecture.

AI summary
A driving handover control device includes a memory and a processor coupled to the memory. In a case in which driving is handed over from a first state in which a vehicle travels in accordance with instruction from a remote operator of the vehicle to a second state in which the vehicle travels in accordance with operation by a passenger of the vehicle, the processor implements a transition from the first state to a third state in which the vehicle travels autonomously without instruction from the remote operator or operation by the passenger, and, after the transition from the first state to the third state, implements a transition from the third state to the second state.
