Solution Overview

Problem

Existing autonomous driving technologies face misjudgment issues with demarcation lines due to temporary construction lines that may not match camera and map information, leading to potential errors in vehicle navigation.

Innovation Solution

A vehicle control system that includes a first recognizer for detecting surrounding demarcation lines and a second recognizer for map demarcation lines, with a judger to assess matching reliability and adjust driving controls based on predetermined conditions, ensuring accurate lane following and obstacle avoidance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If camera demarcation line and map demarcation line are used for lane recognition, then lane positioning accuracy is improved, but misjudgment occurs in construction zones with temporary demarcation lines

Engineering Contradiction:
Improvelane positioning accuracyVSAvoiddemarcation line judgment reliability
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent introduces different vehicles as intermediary objects to verify the correctness of demarcation lines. By detecting whether other vehicles are traveling along the same demarcation line, the system indirectly validates the reliability of the demarcation line before using it for lane positioning, thus resolving the contradiction between positioning accuracy and judgment reliability in construction zones

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system establishes a feedback mechanism where the traveling behavior of different vehicles is used to verify demarcation line correctness. When multiple vehicles consistently follow the same demarcation line, this feedback confirms its reliability; when demarcation lines diverge or other vehicles behave inconsistently, the system identifies potential misjudgments and adjusts its lane recognition accordingly

Inventive Principle:
Principle #23Feedback

AI summary

A vehicle control device of an embodiment includes a first recognizer recognizing a first demarcation line and a different vehicle present around a host vehicle based on detection device, a second recognizer recognizing a second demarcation line demarcating a lane around the host vehicle from map, and a judger judging whether or not the first demarcation line and the second demarcation line match each other. When a plurality of first demarcation lines on one side of the first demarcation lines present on the left and right sides of the host vehicle are recognized, a first one side first demarcation line included in the plurality of recognized one side first demarcation lines and the second demarcation line match each other, and predetermined conditions are satisfied, the judger reduces a reliability of matching information between the first one side first demarcation line and the second demarcation line which have matched each other.
