Follow-Up Travel Speed Control for Partner Vehicle Encounter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In follow-up travel, vehicles have difficulty encountering partner vehicles traveling at similar speeds but at a distance, making it challenging to initiate follow-up travel effectively.
Innovation Solution
A follow-up travel support device that detects surrounding vehicles and adjusts the host vehicle's speed to a different set speed until a partner vehicle is detected, using adaptive cruise control and notifications to facilitate encounter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the host vehicle maintains its set speed, then the host vehicle consumes less fuel and operates efficiently, but the host vehicle cannot encounter partner vehicles traveling at similar speeds at a distance
Solution Approach 1:
The host vehicle's speed is dynamically adjusted based on the detection of partner vehicles. When a partner vehicle is detected at a distance, the host vehicle changes its speed from the set speed to enable encounter. This dynamic speed adjustment resolves the contradiction by making the speed adaptive rather than fixed, allowing the system to switch between fuel efficiency mode and follow-up travel initiation mode as needed.
Solution Approach 2:
The system changes the speed parameter of the host vehicle when specific conditions are met (detection of partner vehicle at distance). By modifying the speed parameter temporarily to enable encounter with partner vehicles, and then returning to the set speed after encounter, the system resolves the contradiction between maintaining constant speed for efficiency and changing speed to initiate follow-up travel.
2Reliability
If the host vehicle changes speed to encounter partner vehicles, then the probability of successful follow-up travel increases, but the fuel consumption and power consumption increase
Solution Approach 1:
The host vehicle performs speed change as a preliminary action when a partner vehicle is detected at a distance, with the intention of enabling encounter and initiating follow-up travel. After the encounter is successful and follow-up travel is established, the host vehicle returns to its set speed. This preliminary speed adjustment is made only when necessary and temporary, minimizing the energy consumption while ensuring successful follow-up travel initiation.
Solution Approach 2:
The host vehicle applies partial speed change rather than continuous speed variation. The speed is adjusted only to the extent necessary to enable encounter with the partner vehicle, and only for the duration needed to establish follow-up travel. This partial action approach minimizes the energy consumption while achieving the necessary outcome of initiating follow-up travel.
Data Source
AI summary
The follow-up travel support device includes a processor configured to detect a surrounding vehicle around a host vehicle, and set a target vehicle speed of the host vehicle. The processor is configured to set the target vehicle speed to a speed different from a set speed of the host vehicle until a partner vehicle that performs a follow-up travel in which a following vehicle follows a preceding vehicle together with the host vehicle is detected as the surrounding vehicle.
