Vehicle Travel Assistance Route Planning for Safe Overtaking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle traveling assistance devices fail to enable a vehicle to continue traveling without stopping or decelerating to an extremely low speed when encountering a stopped or extremely slow-moving vehicle on the travel route.
Innovation Solution
A vehicle traveling assistance device sets a route for the own vehicle to overtake a preceding vehicle or convoy and enter ahead of it, allowing continuous travel without stopping or decelerating, using a control device to determine suitable overtaking conditions and automatically or manually present the route to the operator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the own vehicle maintains automated traveling on the original lane, then the traveling stability is improved, but the vehicle cannot continue traveling without stopping or decelerating to extremely low speed when a stopped or slow-moving vehicle is present
Solution Approach 1:
The system dynamically adjusts the travel route based on real-time detection of preceding vehicles. When a stopped or slow-moving vehicle is detected, the system automatically generates an alternative route that deviates from the original automated traveling path, allowing the own vehicle to maintain normal speed while avoiding the obstacle.
Solution Approach 2:
The system introduces a lateral dimension to the problem by enabling lane changes. Instead of only moving forward or stopping, the own vehicle can change to an adjacent lane to overtake the stopped or slow-moving vehicle, thereby maintaining continuous travel at normal speed while preserving traveling stability through controlled maneuvers.
2Productivity
If the own vehicle changes lane to overtake the preceding vehicle, then the travel continuity is improved, but the traveling safety may be compromised without proper detection
Solution Approach 1:
The system performs preliminary detection of the travel route and surrounding environment before executing a lane change maneuver. The detection unit identifies stopped or slow-moving vehicles and evaluates the safety of the adjacent lane, ensuring that the overtaking action is taken only when it is safe to do so.
Solution Approach 2:
The system continuously monitors the surrounding environment and adjusts the travel route based on real-time feedback. When a stopped or slow-moving vehicle is detected, the system evaluates the situation and determines the appropriate response, either by changing lane to overtake or by adjusting the original route, ensuring safety while maintaining travel continuity.

AI summary
The vehicle traveling assistance device sets a route in which the own vehicle enters in front of the preceding vehicle or the leading vehicle after overtaking the preceding vehicle or the leading vehicle when there is no other vehicle on the traveling route within a first distance ahead of the preceding vehicle or the leading vehicle of the vehicle when there is a preceding vehicle traveling in front of the own vehicle at a running speed equal to or lower than a predetermined speed or a convoy of a plurality of vehicles including the preceding vehicle on the traveling route of the own vehicle.
