Solution Overview

Problem

Existing vehicle-to-vehicle communication systems face challenges in enabling smooth cooperative driving, particularly when leaning vehicles or narrow vehicles are involved, as they tend to run in concentrated formations, making it difficult for other vehicles to merge or navigate through these groups.

Innovation Solution

A vehicle-to-vehicle communication apparatus that identifies and treats groups of narrow vehicles as a single provisional vehicle, generating and outputting provisional information to facilitate smooth cooperative driving by adjusting vehicle positions and communication strategies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If multiple narrow vehicles run in concentrated formation, then the number of vehicles performing cooperative driving increases, but it becomes difficult for other vehicles to merge or navigate through

Engineering Contradiction:
Improvenumber of vehicles performing cooperative drivingVSAvoidease of merging or navigating through vehicle groups
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The patent merges multiple narrow vehicles running in concentrated formation into a single provisional vehicle entity. By treating the group as one unit with aggregated vehicle width and coordinated control, the system maintains the benefits of multiple vehicles performing cooperative driving while enabling other vehicles to navigate through the group as a single obstacle, thus resolving the contradiction between quantity and ease of operation

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If a passenger vehicle tries to enter a lane where leaning vehicles run in concentrated manner, then cooperative driving is required, but the passenger vehicle may not easily cut into the stream of leaning vehicles

Engineering Contradiction:
Improvesmooth cooperative drivingVSAvoidease of lane changing or merging
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a provisional vehicle as an intermediary entity between individual narrow vehicles and other traffic participants. This intermediary aggregates the narrow vehicles into a single controllable unit, enabling smooth cooperative driving through standardized communication protocols while allowing passenger vehicles to merge or change lanes by interacting with the provisional vehicle as a whole rather than individually with each narrow vehicle

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the number of vehicles performing cooperative driving changes during running, then adaptability is improved, but it becomes difficult to maintain smooth cooperative driving

Engineering Contradiction:
Improveability to handle changing vehicle numbersVSAvoidsmooth cooperative driving
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements dynamic formation management where the provisional vehicle structure can adapt to changing conditions. When narrow vehicles enter or leave the concentrated formation, the system dynamically updates the provisional vehicle parameters (vehicle width, position, speed) to reflect the current group state, maintaining smooth cooperative driving while accommodating changes in the number of participating vehicles

Inventive Principle:
Principle #15Dynamics

AI summary

A vehicle-to-vehicle communication apparatus which allows a plurality of vehicles to perform smooth cooperative driving is provided. A vehicle-to-vehicle communication apparatus (60) mounted on a host vehicle (1) includes a host vehicle information storage unit (68), a receiver (62), a provisional information generator (64), and an output controller (65). The host vehicle information storage unit (68) is configured to store vehicle information of the host vehicle (1), which includes vehicle width information related to the vehicle width (W1) of the host vehicle (1) and location information related to the location of the host vehicle (1). The receiver (62) receives sets of vehicle information of client vehicles (102, 103, 104, and 106) sent from transmitters (163a, 163b, 163c, and 163e) of the client vehicles which are capable of performing vehicle-to-vehicle communication. Based on vehicle information, the provisional information generator (64) regards a plurality of narrow vehicles determined as satisfying conditions (A) and (B) as a single provisional vehicle (109). The first condition (A) is that client vehicles and the host vehicle (1) running on the lane (100) of the same running direction as the host vehicle (1) include more than one narrow vehicle. The second condition (B) is that no wide vehicle (104) is in a region formed by line segments (L12, L13, and L23) connecting the narrow vehicles (1, 102, and 103) with one another. The provisional information generator (64) generates provisional information of the provisional vehicle (109) from the sets of vehicle information of the narrow vehicles (1, 102, and 103) which are regarded as the provisional vehicle (109). The output controller (65) outputs the provisional information.
