Vehicle Stop Control Using Feedback Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle stop control systems, unexpected position deviations can occur, especially when similar environments are involved, leading to interference with other vehicles and traffic disruptions, despite existing technologies failing to effectively address these deviations.
Innovation Solution
A vehicle control apparatus that performs stop control using past information, comprising a first executor for initial stop control, a second executor for subsequent stop control, and a corrector that adjusts control contents based on positional deviations from the first stop control to minimize position deviations in the second stop control.

Engineering Contradiction Analysis
1Measurement precision
If stop control is performed using conventional methods, then the vehicle can be stopped at a target position, but position deviation occurs leading to interference with other vehicles and traffic disruptions
Solution Approach 1:
The system obtains difference information between the target stop position and the actual stop position from past stop control operations, and uses this feedback to correct the control contents of subsequent stop controls. This closed-loop feedback mechanism continuously improves positioning accuracy by learning from previous deviations, thereby reducing traffic interference caused by position errors.
Solution Approach 2:
The system corrects the control contents of the second stop control based on past deviation data before the actual second stop control is executed. By performing preliminary correction using historical information, the system proactively prevents position deviation from occurring in the first place, rather than merely reacting to it after the fact.
2Reliability
If stop control is performed without using past information, then the control system remains simple, but similar position deviations are repeatedly generated in similar environments
Solution Approach 1:
The system stores difference information from past stop controls and retrieves it for correcting future operations. This feedback loop enables the system to maintain high reliability and consistency across multiple stop control operations in similar environments, as each operation benefits from corrections based on previously observed deviations.
Solution Approach 2:
The system copies the deviation pattern observed in the first stop control and applies the learned correction to the second stop control. By replicating the successful correction strategy from past experience, the system ensures consistent performance without requiring complex real-time analysis.

AI summary
A vehicle control apparatus is configured to perform a stop control for stopping a vehicle at a target stop position. The vehicle control apparatus is provided with: a first executor configured to perform a first stop control as the stop control such that a first vehicle is stopped at a first target stop position, which is the target stop position; a second executor configured to perform a second stop control as the stop control such that a second vehicle is stopped at a second target stop position after obtaining a difference between the first target stop position and a first actual stop position at which the vehicle is stopped in the first stop control; and a corrector configured to correct control contents of the second stop control on the basis of the difference, before the second vehicle is stopped at the second target stop position.
