Inter-Vehicle Distance Sharing via Common Registration Point
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle communication systems, such as those described in Japanese Patent Application Laid-Open (JP-A) No. 2011-210250, are unable to effectively share the positions of remote vehicles, limiting the ability to formulate driving plans that avoid vehicle switching when parking.
Innovation Solution
An inter-vehicle distance sharing device and method that registers vehicles sharing position information and a common registration point, allowing the control unit to display the distance from each registered vehicle to the common registration point on a display unit, enabling position sharing and driving plan formulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If distance information between concurrent vehicles is known, then relative positioning is achieved, but distance to remote vehicles remains unknown
Solution Approach 1:
The patent introduces a server as an intermediary component that collects position information from multiple vehicles and calculates distances to a common registration point. This mediator approach allows remote vehicle distance information to be obtained without requiring direct vehicle-to-vehicle communication, thus resolving the limitation of only knowing distances between concurrent vehicles while maintaining system simplicity.
2Ease of operation
If vehicles park without knowing each other's distance to home, then parking is simple, but vehicle switching is required
Solution Approach 1:
The patent implements preliminary action by having vehicles register their position information and calculate distances to a common registration point (home) before parking. This advance knowledge of distances allows drivers to formulate parking plans that avoid vehicle switching, thereby saving time while maintaining simple parking operations. The system performs the necessary calculations and information sharing in advance rather than requiring complex real-time coordination.
3Adaptability or versatility
If position information is shared among multiple vehicles, then driving plans can be formulated, but information management complexity increases
Solution Approach 1:
The patent applies universality by designing a server that performs multiple functions: collecting position information from various vehicles, calculating distances to a common registration point, managing registration data, and providing this information to multiple vehicles. This multi-functional approach enables driving plan formulation for multiple vehicles without requiring separate information management systems for each vehicle, thus reducing overall complexity while maintaining adaptability.

AI summary
An inter-vehicle distance sharing device includes a memory and a processor coupled to the memory. The processor coupled to the memory, the processor being configured to register, in advance, vehicles that share position information and a common registration point of each of the vehicles, and display, at a display unit installed at the vehicle of a specific member, a distance from each of the vehicles registered in advance to the common registration point.
