Automatic Driving Control for Tollgate Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic driving control systems for vehicles face challenges in effectively navigating through tollgates, particularly when the road width increases or becomes unrecognizable, making it difficult to maintain automatic driving control.
Innovation Solution
An automatic driving control apparatus that includes an outside environment recognizer, a traveling information detector, a positioning device, and a controller, which determines the presence of a tollgate and adjusts the vehicle's operation mode to a tollgate passing mode by setting a target path based on tollgate position information and map data, allowing the vehicle to pass through tollgates smoothly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle travels through a tollgate section where road width increases or becomes unrecognizable, then the automatic driving control may fail or become ineffective, but maintaining regular traveling mode cannot handle the special road geometry at tollgates
Solution Approach 1:
The system dynamically switches between regular traveling mode and tollgate passing mode based on detection of tollgate sections. When the road width increases or becomes unrecognizable, the controller transitions to tollgate passing mode, which uses predetermined target paths instead of real-time road shape recognition, thereby maintaining automatic driving control effectiveness throughout the tollgate section.
2Ease of operation
If the system uses road shape recognition to determine traveling path, then normal automatic driving control works effectively, but it fails when the road width becomes unrecognizable at tollgates
Solution Approach 1:
The system pre-establishes target paths for tollgate sections based on map information before the vehicle reaches the tollgate. When in tollgate passing mode, the controller guides the vehicle along these predetermined paths without relying on real-time road shape recognition, thus avoiding the difficulty of detecting unrecognizable road widths at tollgates.
3Device complexity
If the vehicle maintains regular traveling mode through tollgates, then the control system remains simple, but the vehicle cannot properly navigate the increased road width and unrecognizable road shape
Solution Approach 1:
The control system is segmented into two distinct modes: regular traveling mode for normal sections and tollgate passing mode for tollgate sections. This segmentation allows the system to use simple road shape recognition during normal travel while switching to a specialized tollgate passing mode that uses predetermined paths and ignores road shape, thereby maintaining both simplicity and reliability in appropriate contexts.

AI summary
An automatic driving control apparatus includes a controller. Upon execution of an automatic driving control of a vehicle, the controller determines, on the basis of a result of positioning and map information, presence or absence of a tollgate within a predetermined distance from the vehicle. The controller makes a transition to a tollgate passing mode, on a condition that the presence of the tollgate is determined within the predetermined distance and an increase in width of the road is further recognized on the basis of a result of recognition of an outside environment. In the tollgate passing mode, the controller sets a first target path on the basis of position information, of the tollgate, that is recognized on the basis of the result of the recognition of the outside environment. The first target path is a target path along which the vehicle is to pass through the tollgate.
