Vehicle Control Device for Driver Attention Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the level of automatic driving increases, driver attention to surroundings monitoring decreases, posing safety concerns when automatic driving is switched to manual driving, and existing technologies like blind spot monitors are not sufficient to support effective surroundings monitoring during this transition.
Innovation Solution
A control device and presentation system that continuously presents visual information from a first position to a second position, using lighting devices or projectors, to guide the driver's visual attention and prompt surroundings monitoring by controlling the presentation of visual stimuli, such as blinking lights, within the driver's stable and surroundings visual fields.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic driving is implemented with high automation level, then driver workload is reduced, but driver attention to surroundings monitoring decreases
Solution Approach 1:
The system activates visual information presentation in advance when transitioning from automatic to manual driving mode. The control unit detects the mode switch and immediately initiates the visual guidance sequence, presenting visual information at the first position before the driver needs to take over control, thereby preparing the driver's attention in advance for the critical handover moment.
Solution Approach 2:
The patent introduces visual information presentation as an intermediary element between the automatic driving system and the driver. This visual mediator guides the driver's attention to specific positions (first and second positions) that require monitoring during the transition, bridging the gap between automated operation and manual control without requiring continuous driver engagement.
2Reliability
If visual information is presented to guide driver attention, then surroundings monitoring is improved, but system complexity increases
Solution Approach 1:
The control unit leverages existing system components (display devices, lighting systems, or projector systems) that are already part of the vehicle's standard equipment. By repurposing these existing multi-functional components for the additional function of attention guidance during mode transition, the system achieves the monitoring improvement without adding dedicated new hardware, thereby minimizing the increase in system complexity.

AI summary
A control device includes a control unit that controls such that visual information is continuously presented from a first position to a second position, which is different from the first position, when a first state in which an operation target, which is a target to be operated by a user, is operated by an operation executing unit that operates the operation target, instead of the user, is switched to a second state in which the operation target is operated by the user.
