Driver Display Guidance for Emergency Vehicle Maneuvers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems fail to provide clear guidance to drivers on appropriate actions when an emergency vehicle is approaching, lacking information on the type of travel maneuver required.
Innovation Solution
A display control device that displays a host vehicle image and an instruction image showing a recommended action based on emergency vehicle information and road conditions, including position, traveling route, and alert, allowing the driver to grasp the necessary action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display unit shows basic vehicle images and surrounding situations, then the driver can see the current state, but the driver cannot understand what action to take when an emergency vehicle approaches
Solution Approach 1:
The system performs preliminary determination of recommended actions based on detected emergency vehicle information and road conditions before the driver needs to respond. The display control unit proactively calculates and presents appropriate actions (stopping, slowing down, maintaining speed) so the driver can quickly understand and execute the correct maneuver when emergency vehicle information is detected.
Solution Approach 2:
The display control unit acts as an intermediary between the detected emergency vehicle information and the driver's decision-making process. It processes the raw detection data (emergency vehicle position, type, road conditions) and transforms it into actionable recommended actions that are visually presented to the driver, bridging the gap between information detection and driver response.
2Reliability
If the system determines recommended action based on emergency vehicle position and road conditions, then the action guidance becomes more accurate, but the system complexity increases
Solution Approach 1:
The system applies different determination logic based on local conditions such as emergency vehicle type, detection position, and specific road conditions. Rather than using a single uniform rule, the display control unit adjusts the recommended action determination according to the specific local context (e.g., different actions for different emergency vehicle types or road conditions), improving accuracy while keeping the complexity manageable through condition-specific rules.
Solution Approach 2:
The system changes the determination parameters and recommended actions based on varying emergency vehicle information and road condition parameters. When different parameters are detected (emergency vehicle position, type, road conditions), the system adjusts its determination logic accordingly, allowing accurate and adaptable action recommendations without requiring a completely complex system.

AI summary
The display control device includes a display control unit configured to display a host vehicle image imitating the host vehicle on a display unit provided around a driver's seat of the host vehicle, and to display an instruction image indicating a recommended action of the host vehicle determined based on information regarding an emergency vehicle approaching the host vehicle and a road condition around the host vehicle.
