Vehicle Information Presentation Apparatus for Targeted Safety Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques fail to reliably present the intention of an autonomous vehicle to target objects, such as pedestrians, without special communication means, as it is unclear who the information is intended for, leading to ineffective safety information transmission.
Innovation Solution
An information presenting apparatus mounted in vehicles acquires driving information, calculates the vehicle's region of movement, and identifies target objects within its surroundings, generating presentation information to encourage specific actions for ensuring safety, ensuring the information is clearly directed to the intended target.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information is displayed on a display externally from the vehicle without specifying the target, then information can be presented to the surroundings, but the intention cannot be reliably transmitted to the specific target object
Solution Approach 1:
The information presentation system is segmented into multiple independent display units positioned at different locations on the vehicle. Each display unit can independently present information to specific target objects in different directions, allowing the system to transmit intentions to multiple targets simultaneously while maintaining clear target identification for each.
Solution Approach 2:
The patent introduces an intermediary processing system that receives vehicle state information, determines appropriate target objects based on spatial relationships and vehicle intentions, and directs information to specific display units. This intermediary layer ensures that information reaches the intended target without requiring complex direct communication between each sensor and display unit.
2Reliability
If the system displays information for multiple potential targets simultaneously, then all surrounding objects receive information, but the specific intended recipient becomes unclear
Solution Approach 1:
Different display units are assigned to different spatial zones around the vehicle, with each display presenting information tailored to the specific target object in its zone. This local quality approach ensures that each target receives information specifically intended for them, maintaining clear target identification while efficiently serving multiple targets through specialized local displays rather than a single general display.

AI summary
According to an embodiment, an information presenting apparatus to be mounted in a vehicle includes hardware circuitry. The hardware circuitry is configured to acquire driving information including a speed and a steering angle of the vehicle. The hardware circuitry is configured to calculate, based on the driving information, an own vehicle region indicating a region in which the vehicle moves. The hardware circuitry is configured to acquire target object position information indicating a position of a target object present in surroundings of the vehicle. The hardware circuitry is configured to generate a pair of target object information and presentation information when the position of the target object is included in the own vehicle region. The target object information identifies the target object present at the position of the target object. The presentation information indicates information that encourages the target object to perform a certain action.
