Solution Overview

Problem

Existing automated vehicle control systems face challenges in ensuring smooth driving at intersections due to inadequate recognition of surrounding situations, leading to inconsistent control and potential safety issues.

Innovation Solution

A vehicle control device and method that includes a recognition unit to assess the intersection situation, determining if it can be recognized at a predetermined level, and a driving control unit that adjusts steering and informs external vehicles accordingly to manage turns and stops at intersections, ensuring safe and smooth navigation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the vehicle switches to manual operation mode at intersections, then the driver can handle complex situations, but smooth automated driving control cannot be realized

Engineering Contradiction:
Improvesafety at intersectionVSAvoidautomated driving control
Core Design Contradiction:
ReliabilityVSExtent of automation

Solution Approach 1:

The vehicle performs preliminary positioning actions before reaching the intersection. When the recognition determination unit determines that the intersection situation can be recognized, the driving control unit performs control to move the vehicle toward the turning direction before reaching the intersection, rather than waiting at the stop line. This preliminary action ensures smooth automated driving while maintaining safety.

Principle #10Preliminary action

2Ease of operation

If the vehicle moves toward the turning direction before the intersection, then smooth driving control is achieved, but safety cannot be ensured when the intersection situation cannot be recognized

Engineering Contradiction:
Improvesmooth driving controlVSAvoidsafety at intersection
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system dynamically adjusts driving behavior based on recognition conditions. When the intersection situation can be recognized, the vehicle moves toward the turning direction before the intersection for smooth control. When recognition is insufficient, the vehicle maintains standard stopping behavior. This dynamic adaptation resolves the contradiction between smooth control and safety.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The recognition determination unit continuously assesses whether the intersection situation can be recognized and provides feedback to the driving control unit. This feedback mechanism enables the system to switch between different driving modes (preliminary positioning vs. standard stopping) based on real-time recognition quality, ensuring both smooth control and safety.

Inventive Principle:
Principle #23Feedback

3Reliability

If the vehicle stops before the intersection when recognition is insufficient, then safety is maintained, but driving continuity is disrupted

Engineering Contradiction:
Improvesafety at intersectionVSAvoiddriving continuity
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system performs preliminary positioning actions before reaching the intersection when recognition is sufficient, allowing the vehicle to begin moving toward the turning direction early. This reduces waiting time at the intersection and maintains driving continuity while ensuring safety through the recognition verification process.

Inventive Principle:
Principle #10Preliminary action

AI summary

A vehicle control device includes a recognition unit, an intersection road recognition determination unit, and a driving control unit. When a subject vehicle turns in a first direction that is one of left and right directions at an intersection road, in a case where it is determined that a situation of the intersection road is able to be recognized at a predetermined degree or more by the intersection road recognition determination unit, the driving control unit performs control of moving the subject vehicle toward a side of the first direction in front of the intersection road, and in a case where it is determined that the situation of the intersection road is not able to be recognized at the predetermined degree or more, the driving control unit suppresses the control of moving the subject vehicle toward the side of the first direction in front of the intersection road.
