Lane Deviation Alarm Control Using Driver Steering Intent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems may excessively execute lane deviation control, failing to perform appropriate deviation suppression based on the driver's situation.
Innovation Solution
A vehicle control system that includes a recognizer to detect surroundings, a steering operation detector to identify lane keeping maneuvers, and a controller to suppress deviation alarms when appropriate steering operations are detected, particularly in curved road conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system outputs deviation alarms when the vehicle is likely to deviate from the travel lane, then lane deviation prevention is improved, but false alarms increase and driver comfort deteriorates
Solution Approach 1:
The system performs preliminary detection of lane keeping steering operations before the vehicle actually deviates from the lane. By detecting the driver's intent to correct lane position through steering torque analysis in advance, the system can suppress alarms that would otherwise be triggered by predicted deviation, thereby reducing false alarms while maintaining safety.
Solution Approach 2:
The system continuously monitors steering torque and provides feedback about driver steering operations. This feedback mechanism allows the system to distinguish between intentional lane keeping maneuvers and actual lane deviation attempts, enabling intelligent suppression of false alarms while maintaining reliable deviation detection.
2Object-affected harmful factors
If the system detects lane keeping steering operations to suppress false alarms, then driver comfort is improved, but detection precision may deteriorate due to torque range filtering
Solution Approach 1:
The system applies different detection criteria to different steering torque ranges. By identifying specific torque ranges characteristic of lane keeping operations and applying targeted detection logic to these local ranges, the system can accurately distinguish lane keeping maneuvers from actual deviation attempts without compromising overall detection precision.
Solution Approach 2:
The system changes the detection parameters dynamically based on the steering torque magnitude and rate of change. By adjusting detection thresholds and criteria according to the specific torque range and operational context, the system maintains high detection precision while effectively identifying lane keeping operations for false alarm suppression.

AI summary
A vehicle control device includes a recognizer configured to recognize surroundings of a vehicle, a steering operation detector configured to detect a steering operation of the vehicle by a driver of the vehicle, a determiner configured to determine whether the vehicle is likely to deviate from a travel lane on the basis of a result of recognition by the recognizer, and a controller configured to output a deviation alarm to the driver when the determiner determines that the vehicle is likely to deviate from the travel lane, in which the controller suppresses an output of the deviation alarm when a lane keeping steering operation for keeping the vehicle in a lane is detected by the steering operation detector.
