Vehicle On-Board Communication Device Wireless Intention Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle communication systems struggle to effectively convey a driver's intention to other vehicles, especially under varying weather conditions or when visibility is poor, leading to potential misunderstandings or unsafe situations.
Innovation Solution
A vehicle on-board communication device that enables wireless communication between vehicles, allowing intention information to be transmitted and received, along with transmitting vehicle information to clarify the source, and includes features like lane entry control and display units to enhance clarity and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lighting-based signals are used to convey driver intention, then the system is simple and inexpensive, but the signals may not be visually recognized under poor weather or visibility conditions
Solution Approach 1:
The patent replaces the optical/mechanical lighting-based signal system with a wireless communication system using radio waves. The communication unit transmits intention information wirelessly between vehicles, eliminating dependence on visual recognition and making the system immune to weather and visibility conditions.
2Reliability
If wireless communication is implemented for intention transmission, then intention information can be conveyed reliably regardless of weather, but the system complexity increases
Solution Approach 1:
The patent integrates the wireless communication unit into the existing vehicle system, allowing it to perform multiple functions: transmitting driver intention, receiving other vehicle intentions, and providing notification to the driver. This multi-functionality reduces overall system complexity despite adding wireless communication capability.
Solution Approach 2:
The notification unit automatically alerts the driver about received intention information from other vehicles without requiring additional manual intervention. The system self-manages the communication process, from receiving signals to notifying the driver, reducing operational complexity.
3Ease of operation
If only intention information is transmitted without source identification, then communication is simple, but ambiguity about the transmission source arises
Solution Approach 1:
The patent combines intention information and transmitting vehicle information into a single wireless transmission package. The communication unit simultaneously transmits both the driver's intention and the vehicle identification, ensuring the receiving vehicle can identify the source without requiring separate communication channels.
Data Source
AI summary
A vehicle on-board communication device is provided with a communication unit that transmits and receives via wireless communication between a host vehicle and other vehicles located in the vicinity thereof intention information relating to an intention of a vehicle occupant, an instruction unit that receives transmission instructions from an occupant of the host vehicle and causes the intention information to be transmitted to the communication unit, and a notification unit that notifies the occupant of the host vehicle about the intention information of an occupant of another vehicle received by the communication unit.
