Vehicle Control Device Dynamic Virtual Route Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems struggle to automatically change travel trajectories in response to obstructions outside designated lanes, leading to potential disturbances in traffic flow during automatic driving.
Innovation Solution
A vehicle control device that recognizes surroundings, detects obstructions, and generates a virtual route by altering a predetermined branching point to adjust the travel trajectory, allowing the vehicle to navigate around obstructions without disrupting surrounding traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle strictly follows the preset route and lane markings, then the vehicle can maintain stable and predictable travel behavior, but the vehicle cannot respond to obstructions outside the lane and will disturb traffic flow
Solution Approach 1:
The system dynamically adjusts the travel trajectory by introducing a virtual route that deviates from the preset route only when obstructions are detected. The branching point is dynamically changed from the original first branching point to a second branching point, allowing the vehicle to adapt to real-time traffic conditions while maintaining overall route stability.
Solution Approach 2:
The virtual route acts as an intermediary between the preset route and the actual traffic conditions. It provides a smooth transition path that allows the vehicle to bypass obstructions without making abrupt changes, thereby maintaining travel stability while responding to environmental factors.
2Productivity
If the vehicle changes trajectory to avoid obstructions, then the vehicle can prevent traffic flow disruption, but the vehicle increases complexity in route determination and control
Solution Approach 1:
The route determination process is segmented into distinct components: the preset route provides the baseline path, and the virtual route provides the adjustment path. This segmentation allows the system to maintain a simple preset route while adding complexity only when necessary through the virtual route, thereby managing overall system complexity.
Solution Approach 2:
The virtual route is pre-calculated and ready to be activated when obstructions are detected. This preliminary preparation allows the system to respond quickly to traffic conditions without performing complex real-time calculations, thus improving traffic flow efficiency while managing computational complexity.
3Device complexity
If the vehicle uses a fixed branching point based on road markings, then the control system remains simple, but the vehicle cannot adapt to surrounding vehicles outside the lane
Solution Approach 1:
The branching point determination mechanism serves multiple functions: it can operate based on preset road markings for normal conditions, and it can dynamically adjust to detect surrounding vehicles and generate virtual routes when necessary. This multi-functionality allows the system to maintain simplicity while gaining adaptability.

AI summary
The present invention provides a vehicle control device in which it is possible to modify the travel trajectory of a vehicle in response to the presence of an obstruction in the vehicle perimeter. In the present invention, the vehicle control device 1 recognizes the surroundings of the vehicle, detects a first branching point in a first route that is preset on a road, and in cases in which a prescribed condition is met by the presence of an obstruction detected from the recognized surroundings when the vehicle is to move along a travel trajectory that is based on at least one second route from among a plurality of second routes that branch from the first branching point, generates a virtual route which branches from the first route at a second branching point differing from the first branching point toward the selected second route, and modifies the travel trajectory on the basis of the generated virtual route.
